    ACL rupture is more common in females than in males. The injury can result in chondral and meniscal damage or chronic instability. Most often ACL rupture occurs during landing after throwing and jumping in ball sports. Many studies have reported on incidence, mechanism of injury and predisposing factors in professional athletes. In contrast, we have investigated the impact of mass sports on predisposing factors for the female ACL rupture. In an empirical analytical study leg-axis dynamics, proprioception and foot load of 44 women participating either in regular mass sports or in no sports were investigated by video analysis and on the Biodex-Stability Platform. Our study demonstrates that mass sports improves proprioception of the knee joint. Non-sportive subjects had an increased valgus leg axis during landing in comparison with mass sport participants. Here, we show to the best of our knowledge for the first time that moderate sports activity has a positive effect on predisposing factors of the female ACL rupture. We conclude that prevention programmes focussed on jumping and proprioception can lower the incidence of female ACL ruptures.

    Balance control improvement is one of the most important goals in sports and exercise. Better balance is strongly positively associated with enhanced athletic performance and negatively associated with lower limb sports injuries. Proprioception plays an essential role in balance control, and ankle proprioception is arguably the most important. This paper reviews ankle proprioception and explores synergies with balance control, specifically in a sporting context. Central processing of ankle proprioceptive information, along with other sensory information, enables integration for balance control. When assessing ankle proprioception, the most generalizable findings arise from methods that are ecologically valid, allow proprioceptive signals to be integrated with general vision in the central nervous system, and reflect the signal-in-noise nature of central processing. Ankle proprioceptive intervention concepts driven by such a central processing theory are further proposed and discussed for the improvement of balance control in sport.

    Full Text Available Realisation of sport activities always demanded certain conditions. Among those, sports facilities are certainly necessary. Since there were important changes in the process of training itself and successful performance, as well as, the results achieved by the sportsmen; there is a need for adequate sports facilities, that include whole variety of systems,equipment and necessities. Nowadays, Sport facilities are not only “the place of event”, but also a condition/necessity in achieving best sport results. It is demanded that these facilities are comfortable, absolutely secure and that they can accommodate transmissions: an opening, the course of sports activities and the announcement of the winner. The kind of sport activity, age, sex; so the “sports level” of the competitors is emphasising the specific demands to wards sports facilities.

    Kinesiology tape has gained significant popularity in recent years and is widely used as an adjunct for treatment and prevention of musculoskeletal injuries. However, evidence regarding its influence on knee proprioception is scarce. The purpose of this study was to evaluate the effect of Kinesiology tape on knee proprioception after physical activity in healthy women. It was hypothesized that Kinesiology tape enhances knee proprioception. Longitudinal analysis, pretest-posttest design. Twelve young women with healthy knees were tested for knee proprioception without the use of Kinesiology tape and wearing Kinesiology tape at the knee. The joint position sense was measured at the start and after a 30-min uphill walking protocol on a treadmill. Outcome was the knee angle deviation. No significant difference of proprioceptive performance between the application with Kinesiology tape and without Kinesiology tape was found after uphill walking (p > 0.05). However, when the participants' results for knee angle deviation were graded into good ( 6.1°), Kinesiology tape significantly enhanced those with poor proprioceptive ability after uphill walking, compared to the untaped knee (p = 0.002). This study has shown that the application of Kinesiology tape did not improve knee proprioception in a group of healthy young women. However, it also has demonstrated that Kinesiology tape provided significant proprioceptive enhancement at the knee joint after uphill walking in healthy women with poor proprioceptive ability. This may support its use in sports medicine for preventing knee injuries. Copyright © 2014 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

    Proprioception, or kinesthesia, is the sense of orientation responsible for perception of body and relative position of its parts. Kinaesthesia is received by receptors located in muscles and tendons. In this study a set of proprioception developing exercises was presented. Proprioception should be restored in case of musculoskeletal and neurological disorders. Proprioception training can also be used as a prophylaxis before starting various sporting activities. Proprioception developing exercises have significant meaning for the elderly, who are at risk of balance disorders. These exercises help developing motor memory and at the same time protect from falls.

    The dramatic advances in efferent neural interfaces over the past decade are remarkable, with cortical signals used to allow paralyzed patients to control the movement of a prosthetic limb or even their own hand. However, this success has thrown into relief, the relative lack of progress in our ability to restore somatosensation to these same patients. Somatosensation, including proprioception, the sense of limb position and movement, plays a crucial role in even basic motor tasks like reaching and walking. Its loss results in crippling deficits. Historical work dating back decades and even centuries has demonstrated that modality-specific sensations can be elicited by activating the central nervous system electrically. Recent work has focused on the challenge of refining these sensations by stimulating the somatosensory cortex (S1) directly. Animals are able to detect particular patterns of stimulation and even associate those patterns with particular sensory cues. Most of this work has involved areas of the somatosensory cortex that mediate the sense of touch. Very little corresponding work has been done for proprioception. Here we describe the effort to develop afferent neural interfaces through spatiotemporally precise intracortical microstimulation (ICMS). We review what is known of the cortical representation of proprioception, and describe recent work in our lab that demonstrates for the first time, that sensations like those of natural proprioception may be evoked by ICMS in S1. These preliminary findings are an important first step to the development of an afferent cortical interface to restore proprioception.

    Full Text Available Sports and economy have discovered each other, hoping to serve common interests. In view of transferring in a more efficient way the information about their products or services to consumers, the business operator finances sports activities for advertising purposes. A company involved in sports sponsorship can instantly transmit the message about its products to millions of potential buyers, thus increasing the market share and hence the profit that it generates. By sponsoring sport it is meant any agreement / convention, under which one party the sponsor makes available to the beneficiary the material resources, financial and / or other benefits in exchange for its association with a sport or sportsman and especially the promise to use this association with sport or sportsman for the purpose of advertising, especially TV advertising. The growing use of athletes as spokespersons for a product is largely due to the ability of athletes to attract public attention and the credibility they enjoy.

    Proprioception plays an important role in the complex mechanism of joint control. Contemporary sport activities impose extremely high physical demands on athletes. Winter sports are played in areas with excessively low temperatures. Moreover, many athletes are subjected to treatments that involve local lowering of the body temperature before, during, and after physical activity. This work reviews the current knowledge regarding the influence of local cryotherapy on the proprioception system. The reviewed literature identified several tests that evaluate different aspects of proprioception. There is no universally agreed protocol, or clear set of criteria for test conditions. The outcomes of different tests and assessments of cryotherapy procedures using different cold modalities are poorly correlated. In general, the published results on the mechanism of cryotherapy effects on proprioception are not uniquely conclusive and are frequently contradictory. Additional high-quality research is required to explicitly answer the following questions: (1) whether local cryotherapy influences all aspects of proprioception; (2) whether the current methods of evaluation are adequate for the exploration of the relationship between cryotherapy and proprioception; and (3) whether the application of local cryotherapy is safe for athletes regarding proprioception. The review clearly showed that there is no comprehensive model relating cryotherapy and proprioception.

  15. Eyelid Opening with Trigeminal Proprioceptive Activation Regulates a Brainstem Arousal Mechanism.

    Directory of Open Access Journals (Sweden)

    Kiyoshi Matsuo

    Full Text Available Eyelid opening stretches mechanoreceptors in the supratarsal Müller muscle to activate the proprioceptive fiber supplied by the trigeminal mesencephalic nucleus. This proprioception induces reflex contractions of the slow-twitch fibers in the levator palpebrae superioris and frontalis muscles to sustain eyelid and eyebrow positions against gravity. The cell bodies of the trigeminal proprioceptive neurons in the mesencephalon potentially make gap-junctional connections with the locus coeruleus neurons. The locus coeruleus is implicated in arousal and autonomic function. Due to the relationship between arousal, ventromedial prefrontal cortex, and skin conductance, we assessed whether upgaze with trigeminal proprioceptive evocation activates sympathetically innervated sweat glands and the ventromedial prefrontal cortex. Specifically, we examined whether 60° upgaze induces palmar sweating and hemodynamic changes in the prefrontal cortex in 16 subjects. Sweating was monitored using a thumb-mounted perspiration meter, and prefrontal cortex activity was measured with 45-channel, functional near-infrared spectroscopy (fNIRS and 2-channel NIRS at Fp1 and Fp2. In 16 subjects, palmar sweating was induced by upgaze and decreased in response to downgaze. Upgaze activated the ventromedial prefrontal cortex with an accumulation of integrated concentration changes in deoxyhemoglobin, oxyhemoglobin, and total hemoglobin levels in 12 subjects. Upgaze phasically and degree-dependently increased deoxyhemoglobin level at Fp1 and Fp2, whereas downgaze phasically decreased it in 16 subjects. Unilateral anesthetization of mechanoreceptors in the supratarsal Müller muscle used to significantly reduce trigeminal proprioceptive evocation ipsilaterally impaired the increased deoxyhemoglobin level by 60° upgaze at Fp1 or Fp2 in 6 subjects. We concluded that upgaze with strong trigeminal proprioceptive evocation was sufficient to phasically activate sympathetically

    To establish whether proprioception and varus-valgus laxity moderate the association between muscle strength and activity limitations in patients with early symptomatic knee osteoarthritis. A cross-sectional study. A sample of 151 participants with early symptomatic knee osteoarthritis from the Cohort Hip and Cohort Knee study. Regression analyses were performed to establish the associations between muscle strength, proprioception (knee joint motion detection threshold in the anterior--posterior direction), varus-valgus laxity and activity limitations (self-reported and performance-based). Interaction terms were used to establish whether proprioception and laxity moderated the association between muscle strength and activity limitations. Proprioception moderated the association between muscle strength and activity limitations: the negative association between muscle strength and activity limitations was stronger in participants with poor proprioception than in participants with accurate proprioception (performance-based activity limitations p = 0.02; self-reported activity limitations p = 0.08). The interaction between muscle strength and varus-valgus laxity was not significantly associated with activity limitations. The results of the present study support the theory that in the absence of adequate proprioceptive input, lower muscle strength affects a patient's level of activities to a greater degree than in the presence of adequate proprioceptive input.

    The patients diagnosed with Ehlers-Danlos Syndrome Hypermobility Type (EDS-HT) are characterized by pain, proprioceptive inacuity, muscle weakness, potentially leading to activity limitations. In EDS-HT, a direct relationship between muscle strength, proprioception and activity limitations has never been studied. The objective of the study was to establish the association between muscle strength and activity limitations and the impact of proprioception on this association in EDS-HT patients. Twenty-four EDS-HT patients were compared with 24 controls. Activity limitations were quantified by Health Assessment Questionnaire (HAQ), Six-Minute Walk test (6MWT) and 30-s chair-rise test (30CRT). Muscle strength was quantified by handheld dynamometry. Proprioception was quantified by movement detection paradigm. In analyses, the association between muscle strength and activity limitations was controlled for proprioception and confounders. Muscle strength was associated with 30CRT (r = 0.67, p = Proprioception was associated with 30CRT (r = 0.55, p proprioceptive inacuity confounded this association. Muscle strength is associated with activity limitations in EDS-HT patients. Joint proprioception is of influence on this association and should be considered in the development of new treatment strategies for patients with EDS-HT. Implications for rehabilitation Reducing activity limitations by enhancing muscle strength is frequently applied in the treatment of EDS-HT patients. Although evidence regarding treatment efficacy is scarce, the current paper confirms the rationality that muscle strength is an important factor in the occurrence of activity limitations in EDS-HT patients. Although muscle strength is the most dominant factor that is associated with activity limitations, this association is confounded by proprioception. In contrast to common belief proprioception was not directly associated with activity limitations but confounded this association

    2016-05-27

    The aim of this work was to compare cortical beta oscillatory activity between young (YA) and older (OA) adults during the assessment of ankle proprioception. We analyzed the response time (RT) to kinesthetic perception and beta event-related desynchronization/synchronization (ERD/ERS) in response to passive ankle movement applied at a slow speed, 0.5°/s. The relationship between ERD/ERS and RT was investigated by classifying the signals into fast-, medium-, and slow-RT. The results showed a temporal relationship between beta oscillation changes and RT for both groups, i.e., earlier ERD and ERS were obtained for trials with faster response time. ERD was larger and delayed in OA compared to the YA, and beta ERS was present only for OA. These findings suggest that a less efficient proprioceptive signaling reaching the brain of OA requires a higher level of brain processing and hence the differences in ERD potentials between YA and OA. Furthermore, the occurrence of ERS in OA might represent a compensatory strategy of active cortical resetting for adequate sensorimotor behavior due to the age-related reduced peripheral input and neuromuscular impairments. Altered balance between excitatory and inhibitory intracortical activity in older adults presumably explains the changes in beta oscillations. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available People with epilepsy are prone to be sedentary compared with the general population. The causes of inactivity are ignorance, prejudice, overprotection, fear and shame. There is no scientific evidence supporting a limitation of physical exercise in persons with epilepsy. The benefits of exercise in these patients are huge. Positive aspects are: physical conditioning, prevention of seizures, emotional wellbeing, social interaction, drug treatment adherence, osteoporosis prevention and better quality of life for patients and their families. Having in mind the individual characteristics, physical exercise should be prescribed and guided. Available evidence underlies the complementary therapeutic effects of physical activity with large positive results at a low cost. Sports or regular physical activity should be a standard indication for persons with epilepsy.

    2012-06-01

    Patellar taping is a common treatment modality for physical therapists managing patellofemoral pain. However, the mechanisms of action remain unclear, with much debate as to whether its efficacy is due to a change in patellar alignment or an alteration in sensory input. The purpose of this study was to investigate the sensory input hypothesis using functional magnetic resonance imaging when taping was applied to the knee joint during a proprioception task. This was an observational study with patellar taping intervention. Eight male volunteers who were healthy and right-leg dominant participated in a motor block design study. Each participant performed 2 right knee extension repetitive movement tasks: one simple and one proprioceptive. These tasks were performed with and without patellar taping and were auditorally paced for 400 seconds at 72 beats/min (1.2 Hz). The proprioception task without patellar taping caused a positive blood oxygenation level-dependant (BOLD) response bilaterally in the medial supplementary motor area, the cingulate motor area, the basal ganglion, and the thalamus and medial primary sensory motor cortex. For the proprioception task with patellar taping, there was a decreased BOLD response in these regions. In the lateral primary sensory cortex, there was a negative BOLD response with less activity for the proprioception task with taping. Limitations This study may have been limited by the small sample size, a possible learning effect due to a nonrandom order of tasks, and use of a single-joint knee extension task. This study demonstrated that patellar taping modulates brain activity in several areas of the brain during a proprioception knee movement task.

    The purpose of the study was to assess the influence of below-knee compression garments on proprioception accuracy under, information processing constraints designed to cause high or low conscious attention to the task. In a counterbalanced, single-blinded, crossover trial, 44 healthy participants (26 male/18 female) with a mean age of 22.7±6.9 years performed an active joint repositioning task using their nondominant and their dominant leg, with and without below-knee compression and with and without conducting a secondary task. Analysis of variance revealed no main effect of leg dominance and no interactions (p's>0.05). However, a main effect was evident for both compression (F 1, 43 =84.23, pknee proprioception under differential information processing constraints. We conclude that proprioception accuracy of the knee joint is significantly enhanced post application of below-knee compression garments and when a secondary task is conducted concurrently with active joint repositioning. The findings suggest that below-knee compression garments may improve proprioception of the knee, regardless of leg dominance, and that secondary tasks that direct attention away from proprioceptive judgments may also improve proprioception, regardless of the presence of compression. Clinical implications are discussed with respect to proprioception in modern.sports and rehabilitation settings. Copyright © 2016 Elsevier B.V. All rights reserved.

    Joint arthroplasty is one of the commonest surgical procedures in orthopedic surgery. In recent years there was an increase in the number of procedures, patient satisfaction and implant survival. Originally, these operations were designed for old patients in order to relieve pain and to enable ambulation. Over the past few years, these operations have become common in younger patients which desire to return to activity, including sports activities. The importance of physical activity is a well known fact. In recent years it became clear that with the proper physical activity the outcomes of the operations are better. There are several types of arthroplasty. Many factors influence the outcome of the operation apart from the post-surgery physical activity. These factors include patient factors, surgical technique and type of arthroplasty. This review summarizes the recommendations for sports activities after hip and knee arthroplasties. These activities are evaluated according to surgeons' recommendations, stress applied on the implant and long term outcomes. The recommended sports activities after joint arthroplasties are walking, swimming and cycling. Soccer, basketball and jogging are not advised. Tennis, downhill skiing and horse riding are recommended with previous experience. There are many more sports activities that patients can participate in, and it is important that the patient discuss the different options prior to the operation. Since these operations are so common, many non-orthopedic physicians encounter these patients in their practice. They should be acquainted with the recommendations for sports activities and encourage them.

    A proprioceptive stimulus consisting of a weight change of a handheld load has recently been shown to elicit an evoked potential. Previously, somatosensory gamma oscillations have only been evoked by electrical stimuli. We conjectured that a natural proprioceptive stimulus also would be able...... contralateral to stimulus side and additionally an unexpected 20 Hz activity was observed slightly lateralized in the frontal central region. The gamma phase locking may be a manifestation of early somatosensory feature integration. The analyses suggest that the high frequency activity consists of two distinct...

    The purpose of the current work was to (1) determine whether low back cutaneous sensitivity could be reduced through the use of a topical lidocaine-prilocaine anesthetic (EMLA(®)) to mirror reductions reported in chronic lower back pain (CLBP) patients, as well as to (2) identify whether reductions in cutaneous sensitivity resulted in decreased lumbar spine proprioception, neuromuscular control and dynamic stability. Twenty-eight healthy participants were divided equally into matched EMLA and PLACEBO treatment groups. Groups completed cutaneous minimum monofilament and two-point discrimination (TPD) threshold tests, as well as tests of sagittal and axial lumbar spine active repositioning error, seated balance and repeated lifting dynamic stability. These tests were administered both before and after the application of an EMLA or PLACEBO treatment. Results show that low back minimum monofilament and TPD thresholds were significantly increased within the EMLA group. Skin sensitivity remained unchanged in the PLACEBO group. In the EMLA group, decreases in low back cutaneous sensitivity had minimal effect on low back proprioception (active sagittal and axial repositioning) and dynamic stability (seated balance and repeated lifting). These findings demonstrate that treating the skin of the low back with an EMLA anesthetic can effectively decrease the cutaneous sensitivity of low back region. Further, these decreases in peripheral cutaneous sensitivity are similar in magnitude to those reported in CLBP patients. Within this healthy population, decreased cutaneous sensitivity of the low back region has minimal influence on active lumbar spine proprioception, neuromuscular control and dynamic stability.

    2010-11-01

    To investigate the effectiveness of a multistation proprioceptive exercise program for the prevention of ankle injuries in basketball players using a prospective randomized controlled trial in combination with biomechanical tests of neuromuscular performance. A total of 232 players participated in the study and were randomly assigned to a training or control group following the CONSORT statement. The training group performed a multistation proprioceptive exercise program, and the control group continued with their normal workout routines. During one competitive basketball season, the number of ankle injuries was counted and related to the number of sports participation sessions using logistic regression. Additional biomechanical pre–post tests (angle reproduction and postural sway) were performed in both groups to investigate the effects on neuromuscular performance. In the control group, 21 injuries occurred, whereas in the training group, 7 injuries occurred. The risk for sustaining an ankle injury was significantly reduced in the training group by approximately 65%. [corrected] The corresponding number needed to treat was 7. Additional biomechanical tests revealed significant improvements in joint position sense and single-limb stance in the training group. The multistation proprioceptive exercise program effectively prevented ankle injuries in basketball players. Analysis of number needed to treat clearly showed the relatively low prevention effort that is necessary to avoid an ankle injury. Additional biomechanical tests confirmed the neuromuscular effect and confirmed a relationship between injury prevention and altered neuromuscular performance. With this knowledge, proprioceptive training may be optimized to specifically address the demands in various athletic activities.

    We recently reported that right-side dominance of the inferior parietal lobule (IPL) in self-body recognition (proprioceptive illusion) task emerges during adolescence in typical human development. Here, we extend this finding by demonstrating that functional lateralization to the right IPL also develops during adolescence in another self-body (specifically a self-face) recognition task. We collected functional magnetic resonance imaging (fMRI) data from 60 right-handed healthy children (8-11 years), adolescents (12-15 years), and adults (18-23 years; 20 per group) while they judged whether a presented face was their own (Self) or that of somebody else (Other). We also analyzed fMRI data collected while they performed proprioceptive illusion task. All participants performed self-face recognition with high accuracy. Among brain regions where self-face-related activity (Self vs. Other) developed, only right IPL activity developed predominantly for self-face processing, with no substantial involvement in other-face processing. Adult-like right-dominant use of IPL emerged during adolescence, but was not yet present in childhood. Adult-like common activation between the tasks also emerged during adolescence. Adolescents showing stronger right-lateralized IPL activity during illusion also showed this during self-face recognition. Our results suggest the importance of the right IPL in neuronal processing of information associated with one's own body in typically developing humans.

    Proprioception is somatic sensation that allows us to sense and recognize position, posture, and their changes in our body parts. It pertains directly to oneself and may contribute to bodily awareness. Likewise, one's face is a symbol of oneself, so that visual self-face recognition directly contributes to the awareness of self as distinct from others. Recently, we showed that right-hemispheric dominant activity in the inferior fronto-parietal cortices, which are connected by the inferior branch of the superior longitudinal fasciculus (SLF III), is associated with proprioceptive illusion (awareness), in concert with sensorimotor activity. Herein, we tested the hypothesis that visual self-face recognition shares brain regions active during proprioceptive illusion in the right inferior fronto-parietal SLF III network. We scanned brain activity using functional magnetic resonance imaging while twenty-two right-handed healthy adults performed two tasks. One was a proprioceptive illusion task, where blindfolded participants experienced a proprioceptive illusion of right hand movement. The other was a visual self-face recognition task, where the participants judged whether an observed face was their own. We examined whether the self-face recognition and the proprioceptive illusion commonly activated the inferior fronto-parietal cortices connected by the SLF III in a right-hemispheric dominant manner. Despite the difference in sensory modality and in the body parts involved in the two tasks, both tasks activated the right inferior fronto-parietal cortices, which are likely connected by the SLF III, in a right-side dominant manner. Here we discuss possible roles for right inferior fronto-parietal activity in bodily awareness and self-awareness. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Full Text Available Sport involvement among children and adolescents has been a central field of research in sport science since years. This paper documents the participation of 11- to 15-year-olds in sport clubs and informal sport activities in Liechtenstein and examines possible gender- and age-specific differences. The analysis is based on four cross-sectional studies from 2004 to 2015 and includes the data of 1’262 children in primary (5th grade and secondary (7th and 9th grades school. According to our findings sports and exercise are considered to be one of the main leisure-time activities for all school levels (irrespective of gender. The percentage of fully sport-abstinent adolescents by 11- and 13-year-olds is about 5 %; by 15-year-olds is around 10 %. The culmination of sports club membership (with current 84.7 % appears to be at the age of 11 (5th grade. After the switch to secondary school the sports club commitment tends to decrease, while the high attendance of the informal sport activities (>85 % shows relatively stable age development. In contrast to other child and youth studies, our data indicates a levelling tendency and dissolution of classic gender differences not only in sports club commitment but also in informal sports among girls and boys.

    Full Text Available Starting from the definition of sport, the author has presented the possibilities its application in the prevention of crime and delinquency. In that context, the author analyzes the rate of juvenile delinquency in specific countries, such as Canada, and underlines the fact that the classical criminal measures do not give adequate results. The author points out that it is, therefore, necessary to apply some other preventive measures, which embody the application of sports and physical activity. The author provides examples of good practice in the states which has achieved the best results in the development of such programs. Finally, in view of the increasing number of reported criminal offences committed by both juveniles and adults, the author highlights the need for developing such programs in the Republic of Serbia.

    2017-03-01

    To explore the effects of kinesiology taping (KT) and athletic taping (AT) on ankle proprioception when tested in functional, full weight-bearing stance. Cross-sectional study. Twenty-four healthy university students participated. Proprioception was measured using the Active Movement Extent Discrimination Apparatus (AMEDA). The three testing conditions: no-taping, KT, AT, and foot tested were randomly assigned. Perceived comfort, support and proprioceptive performance under two taping conditions were recorded. Proprioceptive discrimination scores with 95% CIs for no-taping, KT and AT were 0.81 (0.79-0.84), 0.81 (0.79-0.83), and 0.79 (0.77-0.81). Repeated measures ANOVA showed neither any significant difference associated with taping compared with no-taping (p=0.30), nor any difference between KT and AT (p=0.19). The group was then divided, according to their no-taping scores, into two sub-groups: with scores below the no-taping mean (n=13), and above the mean (n=11). ANOVA revealed a significant interaction (p=0.008) indicating that above-average no-taping performers proprioception scores were worse when taped, whereas below-average performers improved. For both KT and AT, only ratings of perceived comfort when taped were significantly associated with actual proprioceptive performance (both r>0.44, p≤0.03). Other perception ratings (support and performance) were significantly inter-correlated (both r>0.42, p0.31). Taping of the foot and ankle may amplify sensory input in a way that enhances proprioception of poor performers but produces an input overload that impairs proprioception in those who originally performed well when no-taping. Screening of ankle proprioception may identify those who would benefit most from taping. Copyright © 2016 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

  2. Predictive Modeling by the Cerebellum Improves Proprioception

    Because sensation is delayed, real-time movement control requires not just sensing, but also predicting limb position, a function hypothesized for the cerebellum. Such cerebellar predictions could contribute to perception of limb position (i.e., proprioception), particularly when a person actively moves the limb. Here we show that human cerebellar patients have proprioceptive deficits compared with controls during active movement, but not when the arm is moved passively. Furthermore, when healthy subjects move in a force field with unpredictable dynamics, they have active proprioceptive deficits similar to cerebellar patients. Therefore, muscle activity alone is likely insufficient to enhance proprioception and predictability (i.e., an internal model of the body and environment) is important for active movement to benefit proprioception. We conclude that cerebellar patients have an active proprioceptive deficit consistent with disrupted movement prediction rather than an inability to generally enhance peripheral proprioceptive signals during action and suggest that active proprioceptive deficits should be considered a fundamental cerebellar impairment of clinical importance.

    The current review and meta-analysis systematically investigated the effect of joint stabilizers on proprioception, postural stability, and neurological activity. Systematic identification of published literature was performed on online databases; Scopus, PEDro, SportDiscus, and EMBASE, followed by a critical PEDro methodological quality appraisal. Data from the studies were extracted and summarized in a tabular format. Of 2954 records, 50 studies, involving 1443 participants met our inclusion criteria. In the included studies, 60% of studies reported significant enhancements (p  0.05) and 21% of studies reported no effects of joint stabilizers on proprioception and/or postural stability. Meta-analysis of pooled studies demonstrated beneficial effects of joint stabilizers on the knee (95% CI: 0.35°-0.61°) and ankle (at 10: 0.1°-0.65°) joint proprioception, and negligible effects on postural stability (-0.28°-0.19°). The pooled evidence suggests that application of joint stabilizers enhances joint proprioception and stability by not merely altering the mechanical stability of the underlying musculoskeletal structures but by also causing subtle changes in cerebral haemodynamics and musculoskeletal activation. These findings support clinical implications of joint stabilizers as a prophylactic and rehabilitation measure in modern sports and rehabilitation settings. Copyright © 2016 Elsevier Ltd.

    The continuity hypothesis in its general form states that dreams reflect waking life: concerns, thoughts, and experiences (G. W. Domhoff, 1996; M. Schredl, 1999; I. Strauch & B. Meier, 1996). For example, athletes and sport students dream about sports more often than do psychology students, presumably reflecting their engagement in sport activities and sport theory (D. Erlacher & M. Schredl, 2004). In the present study, the authors tested the previously unexamined hypothesis that differences in dream content would directly reflect individuals' differing amounts of waking sport activities. As expected, the amount of time that individuals spent engaged in an activity (sports or reading) was directly related to their percentage of corresponding dreams. Also, individuals reported reading dreams less frequently than they did sport dreams, although reading was more prominent in their waking lives than were sport activities. The findings also indicated that other factors such as emotional involvement and associated worries might be of importance in explaining the relation between waking activities and dream events. Future studies using longitudinal designs would shed more light on this relation and would help derive a more precise formulation of the continuity hypothesis.

The works encompass methodological developments substantiated by investigations of healthy volunteers and two clinical studies of schizophrenia spectrum patients. American psychiatrist Sandor...... Rado (1890-1972) suggested that one of two un-reducible deficits in schizophrenia was a disorder of proprioception. Exploration of proprioceptive information processing is possible through the measurement of evoked and event related potentials. Event related EEG can be analyzed as conventional time......-series averages or as oscillatory averages transformed into the frequency domain. Gamma activity evoked by electricity or by another type of somatosensory stimulus has not been reported before in schizophrenia. Gamma activity is considered to be a manifestation of perceptual integration. A new load stimulus...

    Proprioceptive knee braces have been shown to improve knee mechanics, however much of the work to date has focused on tasks such as slow step down tasks rather than more dynamic sporting tasks. This study aimed to explore if such improvements in stability may be seen during faster sports specific tasks as well as slower tasks. Twelve subjects performed a slow step down, single leg drop jump and pivot turn jump with and without a silicone web brace. 3D kinematics of the knee were collected using a ten camera Qualisys motion analysis system. Reflective markers were placed on the foot, shank, thigh and pelvis using the Calibrated Anatomical Systems Technique. A two way ANOVA with repeated measures was performed with post-hoc pairwise comparison to explore the differences between the two conditions and three tasks. Significant differences were seen in the knee joint angles and angular velocities in the sagittal, coronal and transverse planes between the tasks. The brace showed a reduction in knee valgum and internal rotation across all tasks, with the most notable effect during the single leg drop jump and pivot turn jump. The transverse plane also showed a significant reduction in the external rotation knee angular velocity when wearing the brace. The brace influenced the knee joint kinematics in coronal and transverse planes which confirms that such braces can have a significant effect on knee control during dynamic tasks. Further studies are required exploring the efficacy of proprioceptive braces in athletic patient cohort. Copyright © 2016 Elsevier B.V. All rights reserved.

    Modern therapy options offer haemophiliacs more and more possibilities for an active participation in sports. The purpose of the present study was to investigate the attitude of these patients towards sports, their participation in school and leisure time sports activities, and differences between juveniles and adults. We investigated 44 children and adolescents (aged from 4 to 16 years) and 27 adults (aged from 18 to 72 years) with haemophilia by means of a questionnaire. 79.6% of the juvenile patients participated always or almost always in school sports, while this percentage was significantly (P Sports play an important or very important role in leisure time activities for 75% of the adolescent and 55.5% of the adult haemophiliacs (P sports. There were only slight differences between both groups, regarding their motivation to participate in sports activities. The main reasons involved social aspects and having fun. The results show that the modern therapy of haemophilia probably leads to a more positive attitude towards sports and to a wider spectrum of practised sports. This, however, may be associated with an increasing potential of health risks, which require a high level of sports medical care.

    This systematic review investigated the effect of proprioceptive and balance exercise on outcomes following injury and surgical reconstruction of the anterior cruciate ligament (ACL). Five studies of high quality that offered empirical evidence by comparing one rehabilitation program to another were included in this review. There is some evidence that proprioceptive and balance exercise improves outcomes in individuals with ACL-deficient knees. Improvements in joint position sense, muscle strength, perceived knee joint function, and hop testing were reported following proprioceptive and balance exercise. Only one included study investigated proprioceptive exercise following ACL reconstruction. Benefits were noted in the proprioceptive group for measures of strength and proprioception; however, no benefits were noted for any measures of activity. No detrimental effects--such as increased passive joint laxity or decrease in strength--were noted when compared with standard rehabilitation programs for both ACL-deficient and ACL-reconstructed individuals. Further research is required to determine if proprioceptive and balance exercise improves long-term outcomes such as return to sport.

    2013-09-01

    Anaerobic capacity/anaerobically attributable power is an important parameter for athletic performance, not only for short high-intensity activities but also for breakaway efforts and end spurts during endurance events. Unlike aerobic capacity, anaerobic capacity cannot be easily quantified. The 3 most commonly used methodologies to quantify anaerobic capacity are the maximal accumulated oxygen deficit method, the critical power concept, and the gross efficiency method. This review describes these methods, evaluates if they result in similar estimates of anaerobic capacity, and highlights how anaerobic capacity is used during sporting activities. All 3 methods have their own strengths and weaknesses and result in more or less similar estimates of anaerobic capacity but cannot be used interchangeably. The method of choice depends on the research question or practical goal.

    Common concerns of patients undergoing total hip arthroplasty are whether they can continue with certain recreational and sporting activities or even commence new ones after the procedure. The present paper describes preoperative and postoperative activities, the numbers participating and the time to resume these activities. Between 1 and 2 years after total hip arthroplasty, 216 patients, who had undergone a total of 235 arthroplasties, were surveyed by postal questionnaire to ascertain how the arthroplasty had affected their recreational and sporting ability. Their preoperative and postoperative activity along with the time to resume was recorded. A general hip score and estimate of physical activity was also collected. The number of patients participating in sport increased from 188 preoperatively to 196 postoperatively. Patients stated that the surgery had a beneficial effect on their performance of sporting activities although the number of sporting events decreased. By multiplying individuals by the number of sports they participated in, there were 434 occurrences of sport preoperatively giving a mean for the group of 1.9 sports per patient. Postoperatively this had reduced to 382, giving a mean of 1.7. Five sports showed a significant change for individual patients from pre to postoperation. Those which showed an increase were exercise walking, where 38 patients (16.8%) who did not walk before surgery took up walking afterwards (P aqua aerobics, where 15 took up this activity postoperatively for the first time (P = 0.002). There were three sports which decreased significantly from pre to postoperation. They were, golf where 13 out of 39 (P = 0.005), tennis 13 out of 14 (P = 0.01) and jogging where six out of seven (P = 0.01) patients stopped participating. This study has shown that patients are adopting lower impact activities to participate in after total hip arthroplasty. The total number of patients performing a sport increases postoperatively but the

    Regular exercise reduces cardiovascular and overall mortality. Participation in sports is an important determinant of cardiovascular health and fitness. Regular sports activity is associated with a smaller risk of sudden cardiac death (SCD). However, there is a small risk of sports-related SCD. Sports-related SCD accounts for approximately 5% of total SCD. SCD among athletes comprises only a fraction of all sports-related SCD. Sport-related SCD has a male predominance and an average age of affliction of 45 to 50 years. Survival is better than for other SCD. This review summarizes links between sports and SCD and discusses current knowledge and controversies. Copyright © 2017 Elsevier Inc. All rights reserved.

    Models of sport development often support the assumption that young athletes' psychosocial experiences differ as a result of seemingly minor variations in how their sport activities are designed (eg, participating in team or individual sport; sampling many sports or specialising at an early age). This review was conducted to systematically search sport literature and explore how the design of sport activities relates to psychosocial outcomes. Systematic search, followed by data extraction and synthesis. The Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were applied and a coding sheet was used to extract article information and code for risk of bias. Academic databases and manual search of peer-reviewed journals. Search criteria determined eligibility primarily based on the sample (eg, ages 7 through 17 years) and study design (eg, measured psychosocial constructs). 35 studies were located and were classified within three categories: (1) sport types, (2) sport settings, and (3) individual patterns of sport involvement. These studies represented a wide range of scores when assessed for risk of bias and involved an array of psychosocial constructs, with the most prevalent investigations predicting outcomes such as youth development, self-esteem and depression by comparing (1) team or individual sport participants and (2) youth with varying amounts of sport involvement. As variations in sport activities impact youth sport experiences, it is vital for researchers to carefully describe and study these factors, while practitioners may use the current findings when designing youth sport programmes.

    Full Text Available The anterior cruciate ligament (ACL is an important structure maintaining stability of the knee joints. Deficits in physical stability and the proprioceptive capabilities of the knee joints are observed, when the ACL is damaged. Additionally, a unilateral ACL injury can affect bilateral knee proprioception; therefore, proprioception of the ACL may play a key role in stability. Electroacupuncture therapy has a definite effect nerve regeneration. In this study, cynomolgus monkeys were randomly divided into 4 groups: the model control group, intervention of the injured knee with electroacupuncture (IIKE group, intervention of the bilateral knees with electroacupuncture (IBKE group, and the blank control group. The unilateral ACL injury model was developed in IIKE and IBKE groups; acupuncture points around the knees underwent intervention similarly in the IIKE and IBKE groups. Then, mRNA and protein expressions of NT-3 and TrkC in the dorsal root ganglion and of growth-associated protein-43 in the ACL increased according to reverse-transcription quantitative polymerase chain reaction and Western blotting results. Decreased incubations and increased amplitudes were found for somatosensory-evoked potentials and motor nerve conduction velocity. The finding indicates that electroacupuncture may play an important role in the recovery of proprioception in the ACL by activating the NT-3/TrkC signalling pathway.

    There is a lack of detailed information about habitual physical activity levels and the sports participation of patients after total ankle arthroplasty. The proportion of sports active patients increases after total ankle arthroplasty, and the majority of patients will meet current recommendations for health-enhancing physical activity. Case series; Level of evidence, 4. The authors assessed the pre- and postoperative participation in sports and recreational activities of 101 patients at a mean of 3.7 years after total ankle arthroplasty. Activity levels were determined with use of the University of California at Los Angeles (UCLA) activity scale. The International Physical Activity Questionnaire (IPAQ) was used to quantify habitual physical activity levels and to calculate the proportion of patients meeting current guidelines for health-enhancing physical activity. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used as the clinical outcome measure. Radiographs were studied for tibial and talar radiolucencies, and any association between radiolucencies, activity levels, and sports participation was determined. Preoperatively, 62.4% of the patients were active in sports; 66.3% were active after surgery (P=.56). The patients were active in 3.0 +/- 1.8 different sports and recreational activities preoperatively and in 3.0 +/- 1.6 activities after surgery (P =1.0). The sports frequency remained unchanged, with 2.0 +/- 1.6 sessions per week before total ankle arthroplasty and 2.3 +/- 1.7 sessions per week postoperatively (P=.19). Overall, the patients were active in sports and recreation for 3.9 +/- 3.8 hours per week pre-operatively, and for 4.7 +/- 3.9 hours per week after surgery (P=.14). The most common disciplines after total ankle arthroplasty were swimming, cycling, and fitness/weight training. Sixty-five percent of the patients stated that surgery had improved their sports ability. The UCLA activity levels increased significantly from

    To evaluate the association between sports activities and allergic symptoms, especially rhinitis, among schoolchildren. This longitudinal survey of schoolchildren collected data from questionnaires regarding allergic symptoms based on the International Study of Asthma and Allergies in Childhood (ISAAC) program and sports participation that were distributed to the parents of children at all 12 public primary schools in Ohmi-Hachiman City, Shiga Prefecture, Japan. Data were collected annually from 2011 until 2014, when the children reached 10 years of age. Blood samples were obtained in 2014, and the levels of immunoglobulin (Ig)E specific to four inhalant allergens were measured. Data from 558 children were analyzed. At 10 years of age, prevalence of asthma and eczema did not differ significantly, while rhinitis was significantly higher (p = 0.009) among children who participated in sports. Prevalence of rhinitis increased as the frequency or duration of sports participation increased (p sports (p = 0.03). Among those who participated in continuous sports activities, the prevalence of rhinitis was significantly higher with prolonged eczema (p = 0.006). Sports activities did not increase sensitization to inhalant allergens. Sports activities enhance the prevalence of rhinitis in schoolchildren. Prolonged eczema, together with sports participation, further promotes the symptoms. The mechanisms of these novel findings warrant further investigation. © 2015 John Wiley & Sons A/S.

    Common concerns of patients undergoing total knee arthroplasty (TKA) are whether they can continue with certain recreational and sporting activities or even commence new ones after the procedure. The present study was designed to determine preoperative and postoperative activities, the numbers participating and the time to resume these activities. Between 1 and 2 years after TKA, patients who had undergone 144 arthroplasties, were surveyed by postal questionnaire to ascertain how the arthroplasty had affected their recreational and sporting ability. Their preoperative and postoperative activity along with the time to resume was recorded. The Oxford knee score and estimate of physical activity was also collected. Out of the 144 TKA performed, 122 participated in sport and recreational activity preoperatively and 108 participated postoperatively. Patients stated that the surgery had a beneficial effect on their performance of sporting and recreational activities although the number of sporting events decreased. By multiplying individuals by the number of activities they participated in, there were 254 occurrences of sport and recreational activities preoperatively giving a mean for the group of 1.76 sports/patient. Postoperatively this had reduced to 204, giving a mean of 1.41. Three activities showed a significant change for individual patients from pre- to postoperation. Those which showed an increase were exercise walking, where 19 patients (13.2%) who did not walk before surgery took up walking afterwards (P aqua aerobics, where five took up aqua aerobics postoperatively for the first time (P < 0.025). Golf was the only sport which had a significant fall in participation from pre- to postoperation, with 10 out of 19 golfers giving up (P < 0.025). The present study has shown that patients are adopting lower impact activities to participate in after TKA. The total number of patients performing a sport decreases postoperatively and the total amount of sport played

    For the past few years, children affected by an inherited channelopathy have been counseled to avoid (recreational) sports activities and all competitive sports so as to prevent exercise-induced arrhythmia and sudden cardiac death. An increased understanding of the pathophysiological mechanisms, better anti-arrhythmic strategies, and, in particular, more epidemiological data on exercise-induced arrhythmia in active athletes with channelopathies have changed the universal recommendation of "no sports," leading to revised, less strict, and more differentiated guidelines (published by the American Heart Association/American College of Cardiology in 2015). In this review, we outline the disease- and genotype-specific mechanisms of exercise-induced arrhythmia; give an overview of trigger-, symptom-, and genotype-dependent guidance in sports activities for children with long QT syndrome (LQTS), Brugada syndrome (BrS), catecholaminergic polymorphic ventricular tachycardia (CPVT), or short QT syndrome (SQTS); and highlight the novelties in the current guidelines compared with previous versions. While it is still recommended for patients with LQT1 and CPVT (even when asymptomatic) and all symptomatic LQTS patients (independent of genotype) to avoid any competitive and high-intensity sports, other LQTS patients successfully treated with anti-arrhythmic therapies and phenotype-negative genotype-positive patients may be allowed to perform sports at different activity levels - provided they undergo regular, sophisticated evaluations to detect any changes in arrhythmogenic risk.

    Full Text Available The transmission of positive values between parents and children is generally considered to be the hallmark of successful socialization. As this issue has been widely discussed but surprisingly little researched - especially with reference to core sport values - in this study we aimed to: 1 analyze adolescent athletes’ acceptance of the sport values their parents want to transmit to them (i.e., parental socialization values and 2 examine the relationship between parental involvement in children’s sportive activity and adolescents’ acceptance of their parents’ socialization values. One hundred and seventy-two Italian adolescents (48.3% male, 51.7% female who regularly practice team sports were asked to fill out a questionnaire which included the Youth Sport Values Questionnaire – 2 and the Parental Involvement in Sport Questionnaire. The dyadic correlations revealed that young athletes are in general willing to accept their parents’ socialization values in regards to sport. Moreover, from the relative weight analysis (a relatively new data analysis strategy, it emerged that parental involvement characterized by praise and understanding is the most important predictor of adolescents’ willingness to accept their parents’ sport values. Implications of these results and further expansion of the study are discussed.

    We here ask whether childhood sport participation is positively correlated with adult labour-market outcomes. There are many potential channels for this effect, although, as usual, identifying a causal relationship is difficult. We appeal to two widely-separated waves of Add Health data to map out the correlation between childhood sports and a number of adult labour-market outcomes. We show that different types of childhood sports are associated with both managerial responsibilities and autonomy at work when adult. We take the endogeneity of sport seriously, and appeal to a variety of techniques, including the use of data on siblings, in order to obtain estimates that are as close to unbiased as possible. Last, we compare the effect of sporting activities to that of other leisure activities.* PMID:28798886

  7. Quality of life and sports activities in patients with haemophilia.

    VON Mackensen, S

    2007-09-01

    Quality of life (QoL) is a multidimensional construct pertaining to an individual's physical, emotional, mental, social and behavioural components of well-being and functioning. QoL can be assessed using both generic and disease-specific instruments. QoL assessment in haemophilia is a relatively new area of study; the first data were published in 1990 using generic QoL questionnaires. Only recently have haemophilia-specific questionnaires been developed, first for children and then for adults. Because sports activities include not only physical and functional aspects, but also have an impact on an individual's self-esteem and social interactions, they should play an essential role in QoL assessment. Until the 1970s, persons with haemophilia were advised to avoid any kind of physical activity because of the risk of bleeds. Nowadays, however, the attitude towards sports for patients with haemophilia has changed, and the World Federation of Haemophilia has formulated recommendations concerning physical activities for patients with haemophilia. Although sports activities are recommended, their importance as an integral element in haemophilia management has not yet been widely recognized. Awareness of the importance of sports activities for this patient group has increased, and several sports projects are ongoing. For example, a twice-annual sports camp for adult patients has been held in Germany for the past 2 years; and physical improvements, QoL and subjective training effects are being measured. Another study is investigating the prevalence of sports activities in Italian children with haemophilia and their attitudes towards sports and is also assessing QoL. In Israel, a study is planned in which haemophilic children will participate in a karate training programme, and a QoL evaluation will be added to the physical assessment. In conclusion, sports activities can improve not only physical well-being, but also the emotional and social well-being of persons with

    Full Text Available Background: Regular physical activity is the crucial factor in treating lifestyle diseases. The age of adolescence is considered as the important period of person's life for creation and further maintaining healthy lifestyle habits. We assume that the level of physical activities of young people could be influenced by the possibilities to perform the preferred sporting activities. Objective: The aim of the presented study was to estimate the total amount of performed physical activity and the structure of sport preferences in West Bohemian adolescents. Further to find out the existence of relationships between preferred sport branches and composition of weekly physical activities of girls and boys. Methods: The research was conducted at five selected secondary schools of the Pilsen region, under the total participation of 382 boys and 529 girls. The level of physical activity (PA and sporting preferences was assessed by means of the IPAQ questionnaire and questionnaire of sports preferences, with the use of the internet system INDARES. For the statistical processing of the gained data, the Kruskal-Wallis ANOVA test, crosstabulation tables, and Spearman correlation analysis were used. Results: The results showed that the preference of fitness activities is associated with a higher level of PA in spare time of boys (p = .006, and with intensive PA of boys (p = .014 and girls (p = .044, compared to those, who do not prefer these activities. In addition, in case of boys, we have found statistically significant correlations (p = .022 between the preference of team sports and PA at school. 51.8% of boys and 37.7% of girls, who prefer fitness activities, comply with the recommendation of at least 3 × 20 minutes of intensive PA during one week (out of those, who do not prefer, only 30.5% of boys and 18.1% of girls.

    The purpose of this study was to examine the effect of proprioceptive neuromuscular facilitation (PNF) stretching on musculotendinous unit (MTU) stiffness of the ankle joint. Twenty active women were assessed for maximal ankle range of motion, maximal strength of planter flexors, rate of force development, and ankle MTU stiffness. Subjects were randomly allocated into an experimental (n = 10) group or control group (n = 10). The experimental group performed PNF stretching on the ankle joint 3 times per week for 4 weeks, with physiological testing performed before and after the training period. After training, the experimental group significantly increased ankle range of motion (7.8%), maximal isometric strength (26%), rate of force development (25%), and MTU stiffness (8.4%) (p < 0.001). Four weeks of PNF stretching contributed to an increase in MTU stiffness, which occurred concurrently with gains to ankle joint range of motion. The results confirm that MTU stiffness and joint range of motion measurements appear to be separate entities. The increased MTU stiffness after the training period is explained by adaptations to maximal isometric muscle contractions, which were a component of PNF stretching. Because a stiffer MTU system is linked with an improved the ability to store and release elastic energy, PNF stretching would benefit certain athletic performance due to a reduced contraction time or greater mechanical efficiency. The results of this study suggest PNF stretching is a useful modality at increasing a joint's range of motion and its strength.

    Cross-sectional analyses show a lower incidence of hypertension among endurance athletes compared to the general population, but not among strength athletes or high-performance swimmers. The favorable influence of increased physical activity of the endurance type on cardiovascular regulation is based on peripheral adaptation processes with a reduction in sympathetic tone and elevation of parasympathetic tone. The results are a reduction in catecholamine release, in heart rate, and in mean arterial pressure at the same exercise level. Following chronic strength training there is also a slight reduction in catecholamine levels at the same time the vagal activity decreases, so that no reduction in heart rate and pressure, and thus no economization of cardiac work results. Thus, endurance training is suited for prevention and also for the reduction of blood pressure in primary hypertension and for cardiac relief, while strength training is not. In the case of hypertension, physical activity may only be engaged in when the cardiac functional status and other organ impairments are known. The stages of cardiac adaptation and damage, particularly the differentiation between concentric and eccentric hypertrophy, are particularly important. Exercise ECG and echocardiography are therefore obligatory measures prior to initiating physical activity and for continuous monitoring of hypertension. In primary hypertension Stage I (70-80% according to WHO), in which no cardiac hypertrophy is present, endurance training may be started without drug therapy if diastolic pressure is not greater than 104 mmHg and systolic pressure up to 170 mmHg (mild hypertension). Additional drug therapy does not show any convincing advantages. Higher pressures require adjuvant drug therapy. In concentric cardiac hypertrophy (Stage II), there is clear indication for the use of hypotensive drugs. An endurance sport is to be recommended additionally after normalization of blood pressure; the regression of

    In a context of stagnation of the level of health-enhancing physical activity in Europe, this study examines the geographical stratification of sports participation and physical activity (PA) at the regional level in 28 European countries. While previous research has focused on the national approach, this study considers the regional level across 208 European regions. Individual survey data from the Eurobarometer 80.2 is combined with a regional-level approach to the 208 regions to quantify sports participation and PA at the regional level. The results show important differences and a geographical stratification of sports participation and PA among the European regions, albeit following different patterns. In particular, a north-south gap is identified in terms of PA rates and an east-west gap is detected in terms of sports participation levels. Applying the cluster technique, a taxonomy of four different European regions is developed considering both types of indicators. Finally, the existence of sports spatial spillovers among regions is verified, obtaining a positive autocorrelation among neighbouring regions for being involved in PA and sporting activities. The results may have significant implications in terms of policy measures to improve health through PA and sports participation at the regional level in Europe.

    Full Text Available Objective: Decreased proprioception in Obstetric Brachial Plexus Injury (OBPI reduces the quality of functional movement. Hence, the aim of our study was to evaluate the effects of exercise training with additional proprioceptive equipments on the functional status and proprioceptive sense in children with OBPI. Methods: Forty children with OBPI were randomly divided into two groups. Passive, active and active-assisted range of motion and stretching exercises were included in home-based program (HP group while additional exercises with proprioceptive equipments were also added in the proprioceptive training (PT group. After 6 weeks, proprioceptive perception and functional level were compared to pre-treatment results. Results: Proprioceptive perception at the beginning and at the end of the movement increased in both groups (p<0,05. The Active Movement Scale (AMS scores increased significantly only in some movements in both groups (p<0,05. AMS scores of shoulder abduction and external rotation in PT group were better than HP group (p<0,05. Conclusion: Home exercise program and proprioceptive exercise training both improve proprioceptive sense and functional status in children with OBPI. The proprioceptive exercise training seems to be more beneficial in improving functional movements of shoulder.

    To examine the effect of kinesiology tape (KT) on shoulder strength, proprioception, and scapular kinematics in healthy and Subacromial Impingement Syndrome (SAIS) subjects. Placebo-controlled quasi-experimental study. Research laboratory. A total of 30 physically active subjects participated. Ten healthy subjects with no previous history of shoulder pathology received KT on the dominant shoulder. Twenty subjects with shoulder pain for a minimum of two weeks and presenting with clinical signs of impingement were allotted to receive KT (n = 10) or placebo taping (PT, n = 10) on the involved shoulder. All participants were tested pre- and post-application. Shoulder internal/external rotation (IR/ER) strength was assessed with isokinetic dynamometry (average peak torque/body weight). Shoulder IR/ER proprioception was assessed through threshold to detect passive motion (mean absolute error in degrees). Scapular position at 90° and 120° of shoulder abduction during arm raising/lowering were assessed using a 3D motion analysis system. No significant within group or between group differences were demonstrated for any measure. Taping does not appear to aid/impair shoulder strength, shoulder proprioception, or scapular kinematics. Future research should explore if the effects of KT are time-dependent and similar in other pathologies. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2018-03-01

    This study investigated whether parental participation in organized and unorganized physical activity (PA) was associated with children's participation in extracurricular sport. The sample comprised 834 parents and their children (aged 6-10 years), living in central Portugal. Questionnaires assessed parental PA (organized and unorganized) and extracurricular sport participation in children (number of sports and frequency of participation). Multinomial logistic regression was applied to assess associations between parental and child physical behaviors. Having both parents active was significantly associated with frequent participation in more sports both in girls and boys but a strong relation according to gender was found. The odds of boys practicing more than one sport and more times per week were higher if they had an active father. Girls with physically active mothers, particularly with mothers practicing organized PA in a regular way, were engaged in more sports and practiced sport more times per week. The type of PA practiced by the parents was not related to boys' participation in sport. Future interventions should be family-based and focus on the promotion of higher levels of parental PA, including organized, in order to improve their children's active behaviors.

    Background Sports-associated sudden cardiac arrests (SCAs) occur mostly during middle age. We sought to determine burden, characteristics, and outcomes of SCA during sports among middle aged residents of a large US community. Methods and Results SCA cases aged 35–65 years were identified in a large, prospective, population-based study (2002–2013), with systematic and comprehensive assessment of their lifetime medical history. Of the 1,247 SCA cases, 63 (5%) occurred during sports activities at a mean age of 51.1±8.8 years, yielding an incidence of 21.7 (95%CI 8.1–35.4) per million per year. The incidence varied significantly based on sex, with a higher incidence among men (RR 18.68 95%CI 2.50–139.56) for sports SCA, as compared to all other SCA (RR 2.58, 95%CI 2.12–3.13). Sports SCA was also more likely to be a witnessed event (87 vs. 53%, Psports-associated SCA (23.2 vs. 13.6%, P=0.04). Sports SCA cases presented with known pre-existing cardiac disease in 16%, ≥1 cardiovascular risk factor in 56%, and overall, 36% of cases had typical cardiovascular symptoms during the week preceding SCA. Conclusions Sports-associated SCA in middle age represents a relatively small proportion of the overall SCA burden, reinforcing the idea of the high benefit-low risk nature of sports activity. Especially in light of current population aging trends, our findings emphasize that targeted education could maximize both safety and acceptance of sports activity in the older athlete.

    The present study evaluated effects of exercise training on the proprioception sensitivity, postural stability, and the likelihood of slip-induced falls. Eighteen older adults (6 in balance, 6 in weight, and 6 in control groups) participated in this study. Three groups met three times per week over the course of eight weeks. Ankle and knee proprioception sensitivities and postural stability were measured. Slip-induced events were introduced for all participants before and after training. The results indicated that, overall, strength and postural stability were improved only in the training group, although proprioception sensitivity was improved in all groups. Training for older adults resulted in decreased likelihood of slip-induced falls. The study suggested that proprioception can be improved by simply being active, however, the results suggested that training would aid older adults in reducing the likelihood of slip-induced falls.

    Full Text Available Abstract Attitude is one of the most important predictor variables in relation to behavioral intentions regarding physical activity. Thus, this study aims to determine the influence of attitudes towards physical activity. The study comprised a sample of 1129 individuals (507 men and 622 women age between 12 and 58 years ( = 18 sd = 4.03. To collect the data, the Scale of Attitudes Towards Physical Activity and Sports (Dosil, 2002 was based on the Portuguese version (Cid, Alves, & Dosil, 2008. The results show that attitudes towards physical activity and sports are more positive in younger male individuals, who do not attend higher education, who regularly engage in physical activity and whose parents engage in physical/sports activity themselves.

    Increased sport facility proximity is associated with higher likelihood of meeting physical activity (PA) recommendations in western studies, but it is uncertain whether the findings can be generalized to the Chinese population. From September 2012 to December 2012, 3926 participants drawn from China using a multi-stage sampling strategy were invited to participate in the Study of Community Sports in China. Participants' demographics, commuting time to the nearest sport facility and PA levels were assessed. Among 3926 participants included (51.2% female) in the final analysis, 878 (22.4%) of them met the PA recommendation. Participants who spent ≥30 minutes in commuting time had 80% odds [odds ratio (OR): 0.80 (95% CI: 0.65-0.98)] of meeting the PA recommendation compared to those who spent less than 10 minutes. For every 10-minute increment in commuting time, the odds reduced by 6% [OR = 0.94 (0.88-0.99)]. The observed associations were not appreciably modified by age, gender or education level. In this cross-sectional community-based study, we found that residents in China were less likely to meet the PA recommendation if they needed more commuting time to the nearest sport facility. Increasing sport facility proximity may be effective in improving the PA levels in the Chinese population.

    The increase in quality and life expectancy, often leads to many patients asking the glaucoma specialist whether some sports, activities or hobbies would affect their illness. The aim of this article is to establish guidelines for patients, based on the scientific evidence of published papers. Review of all published articles on glaucoma and sports or other activities. The papers were classified according to the level of scientific evidence based on the Oxford Centre for Evidence-Based Medicine classification. Aerobic sports are beneficial for the patient. Yoga indoor sports or relaxation techniques should be avoided if Valsalva manoeuvres are performed or the head is placed very low. Also, the patients must avoid sudden changes in height. Intense heat does not seem to lead to progression of glaucoma, but intense cold can affect patients with vascular dysregulation. Activities using the near vision slightly reduce the intraocular pressure. The use of wind instruments may raise intraocular pressure, depending on the technique used. Certain sports and activities may have an influence on the onset or progression of glaucoma. Glaucoma specialists should have adequate information about the scientific evidence in the publications, in order to properly advise the patients. Copyright © 2017 Sociedad Española de Oftalmología.

    The aim of this research was to compare the levels of perceived health literacy among adolescents who do or do not participate in sports club activities. Organized sport club activities reach a high proportion of adolescents, and have the potential to contribute to the development of their health literacy. The cross-sectional data on health literacy among school children in Finland (aged 13 and 15, n=3852) were measured, as a part of the Health Behaviour in School-Aged Children (HBSC) study, using the Health Literacy for School-aged Children (HLSAC) instrument. Sports club participation and its association with health literacy were examined in relation to age, gender, family affluence, school achievement, and physical activity. The statistical analyses included cross-tabulation and the multilevel mixed-effects logistic regression analyses. Perceived health literacy was higher among adolescents who participated in sports club activities. This conclusion was valid for boys and girls, for both age groups, among those who were physically active 6-7 days a week, had at least moderate school achievement, and those who belonged to the middle or high affluence families. From the health literacy perspective, participation in sports club activities was especially beneficial for those having low or moderate school achievement level. The sports club setting may work towards equalizing health literacy differences related to school achievement. However, the clubs should ensure that access is available to as many adolescents as possible; by this means they may spread beneficial influences, supporting the development of health literacy among broader population groups.

    The purpose of this study was to evaluate the validity and interrater reliability of the Observational System for Recording Activity in Children: Youth Sports (OSRAC:YS). Children (N = 29) participating in a parks and recreation soccer program were observed during regularly scheduled practices. Physical activity (PA) intensity and contextual factors were recorded by momentary time-sampling procedures (10-second observe, 20-second record). Two observers simultaneously observed and recorded children's PA intensity, practice context, social context, coach behavior, and coach proximity. Interrater reliability was based on agreement (Kappa) between the observer's coding for each category, and the Intraclass Correlation Coefficient (ICC) for percent of time spent in MVPA. Validity was assessed by calculating the correlation between OSRAC:YS estimated and objectively measured MVPA. Kappa statistics for each category demonstrated substantial to almost perfect interobserver agreement (Kappa = 0.67-0.93). The ICC for percent time in MVPA was 0.76 (95% C.I. = 0.49-0.90). A significant correlation (r = .73) was observed for MVPA recorded by observation and MVPA measured via accelerometry. The results indicate the OSRAC:YS is a reliable and valid tool for measuring children's PA and contextual factors during a youth soccer practice.

    [Purpose] The purpose of this study was to compare two methods for the muscle stabilization of the trunk of patients with chronic low back pain. The methods comprised combination patterns of proprioceptive neuromuscular facilitation (PNF) and ball exercise. [Subjects and Methods] The subjects were 40 volunteers who had low back pain. All subjects were randomly assigned to either a group which received proprioceptive neuromuscular facilitation or a group which performed ball exercise. Measurements were taken four times in total, at pre-intervention, two weeks later, four weeks later, and six weeks later. The main measurement methods used were the visual analogue scale (VAS) for pain and electromyography (EMG) for muscle activity. [Results] VAS and EMG activity were significantly reduced in the PNF combination pattern group and the ball exercise group. A comparison of the groups showed significant differences. In VAS and EMG activity; in particular, the combination pattern group using PNF increased EMG activity more than the ball exercise group did after six weeks of intervention. [Conclusion] This study showed that PNF combination pattern training for six weeks was more effective for patients with low back pain than performing ball exercise.

    The NASA Short-term Prediction Research and Transition (SPoRT) program is a partner with the GOES-R Proving Ground (PG) helping prepare forecasters understand the unique products to come from the GOES-R instrument suite. SPoRT is working collaboratively with other members of the GOES-R PG team and Algorithm Working Group (AWG) scientists to develop and disseminate a suite of proxy products that address specific forecast problems for the WFOs, Regional and National Support Centers, and other NOAA users. These products draw on SPoRT s expertise with the transition and evaluation of products into operations from the MODIS instrument and the North Alabama Lightning Mapping Array (NALMA). The MODIS instrument serves as an excellent proxy for the Advanced Baseline Imager (ABI) that will be aboard GOES-R. SPoRT has transitioned and evaluated several multi-channel MODIS products. The true and false color products are being used in natural hazard detection by several SPoRT partners to provide better observation of land features, such as fires, smoke plumes, and snow cover. Additionally, many of SPoRT s partners are coastal offices and already benefit from the MODIS sea surface temperature composite. This, along with other surface feature observations will be developed into ABI proxy products for diagnostic use in the forecast process as well as assimilation into forecast models. In addition to the MODIS instrument, the NALMA has proven very valuable to WFOs with access to these total lightning data. These data provide situational awareness and enhanced warning decision making to improve lead times for severe thunderstorm and tornado warnings. One effort by SPoRT scientists includes a lightning threat product to create short-term model forecasts of lightning activity. Additionally, SPoRT is working with the AWG to create GLM proxy data from several of the ground based total lightning networks, such as the NALMA. The evaluation will focus on the vastly improved spatial

    Full Text Available The main aim of this study was to examine the differences in motivation to participate in sport activities among sports students from three different countries. On a sample of 390 sports students from Slovenia, Croatia and Germany we studied what motivates an interest in being sports active. The sample was stratified across the choice to attend table tennis lessons at all three institutions and all students have completed the Participation Motivation Questionnaire (PMQ. The results revealed that the latent structure of the types of sports students' motives consisted of six factors (sport action with friend, popularity, fitness & health, social status, sports events, relaxation through sports. We also found significant sex differences in motivation to participate in sport activities for all sports students from the three different countries. We did not find relevant age-based differences among the students, and this is the only initial hypothesis that we can reject.

    An adequate level of physical activity has a substantial effect on both mental and physical human health. Physical activity is largely dependent on the function of the musculoskeletal and articular system. One of the most frequent diseases of this system is degenerative joint disease. Due to the changing and more demanding lifestyles and patients' willingness to be involved in sports activity, the expectations of hip joint arthroplasty are becoming increasingly high. Alleviating pain ceases to be the only reason for which patients choose surgical interventions, while the expectations often include involvement in various sports. Only few studies contain recommendations concerning the frequency, type and intensity of sports activity which are acceptable after hip joint arthroplasty. The aim of the study was to evaluate function and physical activity of people following cementless short-stem hip joint arthroplasty in the observation of at least five years. The study group comprised 106 patients who underwent total hip arthroplasty due to degenerative joint diseases, chosen according to inclusion criteria. Patients underwent routine physical examinations following the Harris Hip Score protocol, responded to the UCLA scale and questionnaires concerning pre-surgical and current physical activity. Our results demonstrated that hip joint arthroplasty in people suffering from degenerative joint diseases has a beneficial effect on their level of functioning and physical activity. Although physical activity and the level of functioning obviously reduced as a person aged, the level of physical activity continued to be very high in both groups, with function of the hip joint evaluated as very good.

    It was first suggested that disordered proprioception was a core feature of schizophrenia by Sandor Rado in 1953. Using a recently designed proprioceptive event-related potential paradigm based on a change of load, we studied 12 unmedicated male out-patients with schizophrenia and 24 controls....... In the patients, the early contralateral parietal activity was delayed and later central activity had increased amplitude, but gating was unaffected. The results could be understood within the "deficiency of corollary discharge" model of schizophrenia but not within the "filtering" theory. Further studies...

    2008-06-01

    The Out of School Hours Sports Program (OSHSP) aimed to provide structured sporting experiences and community links to local clubs for children in Out of School Hours Care (OSHC). The OSHSP involved 17 State Sporting Associations (SSAs), 71 OSHC Services and local club representatives. This study explored children's participation in sport in and outside the OSHSP and parental intention for participation in sport in and outside the OSHSP. Surveys were received from 211 children (76 girls and 125 boys; mean age=7.9 years, S.D.=1.7) and their parents/guardians (37.9% response rate). OSHC is characterised by freedom of choice of participation in activities by children. The OSHSP was used to provide an opportunity to choose to participate in a sport while attending OSHC. At the OSHC Services surveyed, between 7.1 and 100% of the children attending OSHC chose to participate in the OSHSP. Of those children who chose to participate, 85% were participating in a sport, usually a different sport to the one offered in the OSHSP. This participation was largely club-based (49.8%), most often once a week for training and competition (55.2%). Parental intentions for children's participation in the OSHSP sports varied with respect to the number of years attending the OSHSP, where children played and trained in their main sport, and how many times a week a child played and trained in their main sport. Older children tended to play and train for sport more times per week and had been attending the OSHC for more years than younger children.

    Coracoid fractures sustained during sporting activities are rare. Previous reports are limited to individual case reports, small case series, and retrospective analyses. To systematically review the literature and identify coracoid fractures sustained during sporting activities to determine fracture prevalence, sporting activities/mechanisms, management, and time to return to sport. Systematic review. A systematic review was conducted investigating all studies in the literature published between January 1970 and April 2017 that reported on athletes sustaining coracoid fractures during sporting activity. The systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and used PubMed, Biosis Previews, SPORTDiscus, PEDro, and EMBASE databases. Inclusion criteria were studies detailing (1) coracoid fractures with reported sporting activity causing injury, (2) fracture management (operative vs nonoperative), and (3) patient outcome. Exclusion criteria were (1) studies concerning fractures secondary to nonsporting activities (mechanical falls, motor vehicle accidents) and (2) studies not reporting fracture management or patient outcomes. Sporting activities, the presence or absence of associated acromioclavicular (AC) joint injury, fracture management, patient outcomes, and time to return to sport were analyzed. A total of 21 cases of coracoid fractures sustained during sporting activity were identified; acute trauma was responsible for 71% (n = 15/21) of fractures, and the remaining injuries were secondary to fatigue fractures. Concurrent AC joint injury was present in 60% (n = 9/15) of athletes sustaining acute trauma and in no athlete with fatigue fractures. Fractures were treated conservatively in 76% (n = 16/21) of patients, with only 19% (n = 3/16) of athletes reporting complications. Mean overall time to return to sport was 2.8 ± 2.0 months; no significant differences in return to sport were noted in

    Proprioception can be impaired in gradual-onset musculoskeletal pain disorders and following trauma. Understanding of the role of proprioception in sensorimotor dysfunction and methods for assessment and interventions is of vital importance in musculoskeletal rehabilitation. In Part 1 of this two-part Masterclass we presented a theory-based overview of the role of proprioception in sensorimotor control, causes and findings of altered proprioception in musculoskeletal conditions, and general principles of assessment and interventions. The aim of this second part is to present specific methods for clinical assessment and interventions to improve proprioception in the spine and extremities. Clinical assessment of proprioception can be performed using goniometers, inclinometers, laser-pointers, and pressure sensors. Manual therapy, taping, and bracing can immediately enhance proprioception and should be used to prepare for exercise interventions. Various types of exercise (active joint repositioning, force sense, co-ordination, muscle performance, balance/unstable surface, plyometric, and vibration training) should be employed for long-term enhancement of proprioception.

    Sports activity after surgical AC joint stabilisation has not been comprehensively evaluated to date. The aim of this study was to determine rate, level and time to return to sports after AC joint stabilisation and to identify the influence of overhead sports on post-operative sports activity. In this retrospective case series, a total of 68 patients with a high-grade AC joint dislocation (Rockwood type V) were stabilised using a single TightRope technique. Fifty-five patients (80.9 %) with median age of 42.0 (range, 18-65) years completed questionnaires regarding sports activity before and after surgery. Clinical outcome and complications were also evaluated. Forty-three patients participated in sports regularly before injury. Their sports activity was rated according to Allain, and non-overhead and overhead sports were differentiated. At median follow-up of 24 (18-45) months, 41 of 43 patients (95.3 %) had returned to sports. 63 % returned to the same sports activity as before injury. 16.3 % needed to adapt the type of sports to reduce demanding activities. 11.6 % reduced the frequency and 32.5 % the intensity of sports. The median time to return to sports was 9.5 (3-18) months. Overhead athletes (Allain Type III and IV) had to reduce their sports activity significantly more often (11.8 vs. 53.8 %; p = 0.011) and needed more time to return to sports (9.5 vs. 4.5 months; p = 0.009). After stabilisation of AC joint dislocation, the majority of patients returned to sports after a substantial period of time. Overhead athletes, in particular, required more time and had to considerably reduce their sports activity. The findings impact therapeutic decision-making after AC joint injury and help with the prognosis and assessment of rehabilitation progress. IV.

    2017-12-01

    The study examined developmental participation patterns of international top athletes. Pairs of 83 international medallists (including 38 Olympic/World Champions) and 83 non-medallists were matched by sport, age and gender. A questionnaire recorded their volume of organised (coach-led) practice/training in their respective main sport and in other sports through childhood, adolescence and adulthood, and also involvement in non-organised (peer-led) sport activity. Analyses revealed that the medallists started practice/training in their main sport at an older age than non-medallists and accumulated slightly, but significantly less main-sport practice/training through childhood/adolescence. But they participated in more practice/training in other sports, particularly before entering their main sport. The medallists also maintained engagement in other sports over more years and specialised later than the non-medallists. Other sports engaged in were mostly unrelated to an athlete's main sport. The results were robust across different types of sports. The observations are reflected against tenets of the "deliberate practice" and "Developmental Model of Sport Participation" frameworks. Early diversified practice and learning experiences are discussed relative to the expansion of youngsters' potential for future long-term learning. In elite athletes, interaction of sport-specific practice/training with early other-sports participation mostly facilitates long-term attainment of international senior medals.

    Full Text Available An adequate level of physical activity has a substantial effect on both mental and physical human health. Physical activity is largely dependent on the function of the musculoskeletal and articular system. One of the most frequent diseases of this system is degenerative joint disease. Due to the changing and more demanding lifestyles and patients’ willingness to be involved in sports activity, the expectations of hip joint arthroplasty are becoming increasingly high. Alleviating pain ceases to be the only reason for which patients choose surgical interventions, while the expectations often include involvement in various sports. Only few studies contain recommendations concerning the frequency, type and intensity of sports activity which are acceptable after hip joint arthroplasty. The aim of the study was to evaluate function and physical activity of people following cementless short-stem hip joint arthroplasty in the observation of at least five years. The study group comprised 106 patients who underwent total hip arthroplasty due to degenerative joint diseases, chosen according to inclusion criteria. Patients underwent routine physical examinations following the Harris Hip Score protocol, responded to the UCLA scale and questionnaires concerning pre-surgical and current physical activity. Our results demonstrated that hip joint arthroplasty in people suffering from degenerative joint diseases has a beneficial effect on their level of functioning and physical activity. Although physical activity and the level of functioning obviously reduced as a person aged, the level of physical activity continued to be very high in both groups, with function of the hip joint evaluated as very good.

  1. Eye muscle proprioception is represented bilaterally in the sensorimotor cortex

    2016-01-01

    The cortical representation of eye position is still uncertain. In the monkey a proprioceptive representation of the extraocular muscles (EOM) of an eye were recently found within the contralateral central sulcus. In humans, we have previously shown a change in the perceived position of the right eye after a virtual lesion with rTMS over the left somatosensory area. However, it is possible that the proprioceptive representation of the EOM extends to other brain sites, which were not examined in these previous studies. The aim of this fMRI study was to sample the whole brain to identify the proprioceptive representation for the left and the right eye separately. Data were acquired while passive eye movement was used to stimulate EOM proprioceptors in the absence of a motor command. We also controlled for the tactile stimulation of the eyelid by removing from the analysis voxels activated by eyelid touch alone. For either eye, the brain area commonly activated by passive and active eye movement was located bilaterally in the somatosensory area extending into the motor and premotor cytoarchitectonic areas. We suggest this is where EOM proprioception is processed. The bilateral representation for either eye contrasts with the contralateral representation of hand proprioception. We suggest that the proprioceptive representation of the two eyes next to each other in either somatosensory cortex and extending into the premotor cortex reflects the integrative nature of the eye position sense, which combines proprioceptive information across the two eyes with the efference copy of the oculomotor command.

    Athletes participating in upper-extremity-dominant sports such as softball and volleyball are at increased risk for glenohumeral-joint pain and injury. For these athletes, an integral part of many injury-prevention and -rehabilitation programs includes improving joint proprioception. One way to measure joint proprioception is through the reproduction of joint angles, or joint-reposition sense (JRS). Kinesiology tape is purported to enhance neuromuscular feedback; therefore, it may influence JRS. However, conflicting findings and the lack of research in the upper extremity warrant further investigation. To determine the effects of kinesiology tape on shoulder-joint proprioception by actively reproducing joint angles, or measurement of JRS. Randomized controlled trial. College laboratory. 9 men and 7 women 24 ± 3 y old. SpiderTech kinesiology tape precut Shoulder Spider was applied to the shoulder of participants block randomized to the experimental group, following product-specific instructions, to measure its influence on JRS compared with a control group. JRS-error scores in shoulder flexion, extension, internal rotation, and external rotation (ER). There was a significant interaction between groups pre- to postintervention resulting in decreased JRS errors in flexion (P = .04) and ER (P = .03) in the experimental compared with the control group. The 95% confidence intervals suggest a clinically relevant difference in the variability of JRS errors between postintervention movements for the experimental group in flexion and ER, such that the control group demonstrated much more variability in JRS errors than the experimental group. After the application of kinesiology tape the JRS errors were smaller in flexion and ER. This may be of clinical significance in improving proprioception and thus improving joint stability. Additional research should determine the effectiveness of kinesiology tape in reducing joint injury.

    Full Text Available Torrance tests of creative thinking have been widely used to measure the impact of different items such as creativity on different groups of children. In this study, we perform an empirical study to measure the effects of endurance, power-based and flexibility on a group of children's creativity, originality and flexibility. The study chooses a sample of 341 from 2978 preschool children and distributes a questionnaire among them where 153 were female and 188 of them were male. Cronbach alpha for creativity, originality and fluency were calculated as 0.814, 0.822 and 0.788, respectively. The results of our study indicate that there are some positive and meaningful relationship among three components of creativity, originality and fluency before and after accomplishing test. The impact of test was measured for three types of sport activities including endurance, power-based and flexibility tests. After applying 32 sessions of sporting games, flexibility games represent a mean value of 32.40, which is higher than the other two tests and it maintains meaningful value compared with two other sporting tests of endurance and power base tests.

    Full Text Available The modern world imposes strict conditions on people in various types of activities. A huge amount of processed information, tight timelines and other factors may cause people’s inability to cope with their tasks. Thus, there is a popular habit to put off the work without thinking about the consequences. This trait called procrastination is inherent to a million people all over the world. The problem of procrastination is just beginning to develop in Russia. Nowadays lots of foreign research and foreign questionnaires are being translated and approbated. The aim of this research is to identify the level of athletes’ procrastination, and define the differences of procrastination patterns in individual and team sports athletes. Also we want to study the relationship between procrastination and athletes’ personal characteristics such as extroversion, neuroticism, control over the actions, motivation to success, anxiety, time perspective and decision-making style (coping, and also indicators of state anxiety using a sample of individual athletes (boxing, unarmed self-defence, judo, karate, kickboxing, wrestling, taekwondo and teams (hockey, football, volleyball. Correlation analysis shows structural differences of procrastination manifestations in different types of sport. Regression analysis shows that in athletes of individual sports (model: p = 0,002, adjusted R2 = 0,368 there is only one significant predictor of procrastination - the negative past (p = 0,007, β = 0,495.

    This overview reports published data about the interaction between physical activity and sport during and after cancer on one hand and improvement in psychological parameters, survival and biological mechanisms underlying this effect on the other hand. Practising physical activity and sport during cancer modifies parameters assessing fatigue and quality of life and reduces symptoms of depression. An association also exists between the practise of physical activity and sport and overall and cancer-specific survivals, especially after breast cancer, colon cancer and prostate cancer. These benefits seem to be mediated by a modification of circulating levels of estrogens, insulin, IGF-1 and by a decrease in insulin-resistance, by alterations in the secretion of adipokines, and by a reduction in chronic inflammation through decreased levels of cytokines. There exist some obstacles to the practise of physical activity. These obstacles are mainly related to a fear of pain induced by physical activity and to overweight. These programmes of physical activity and sport cannot be offered to all patients since there are several contra-indications, with some being present since the initial visit and others appearing during cancer management either due to disease progression or related to iatrogenic effects. Whereas benefits from physical activity and sport among cancer patients seem obvious, there are still several pending clinical and biological issues. Copyright © 2014 Elsevier Ireland Ltd.

    2012-06-01

    Full Text Available The low level of physical fitness of intellectually disabled individuals is most often the result of a sedentary lifestyle and the lack of the possibility for these individuals to take part in various forms of physical activity, and as a consequence these individuals are often unable to take part in any form of planned physical activities, are unable to adequately perform everyday activities and have limited abilities for performing workrelated duties. Regular physical activity can have a preventive effect, can reduce health risks and prevent the onset of various illnesses, as well as to promote an active lifestyle and increase physical and work capacities among the members of this particular population. Sport can play an important role in the life of individuals with intellectual disability as it represents a good basis for the development of physical and cognitive abilities. Team sports, which include interaction among a large number of people, a decision-making processes in a variety of situations and the understanding of the game itself in its constituent parts can be used as an effective and practical treatment of individuals with intellectual disability.

    Full Text Available Advertising is an attractive promotional tool for marketers who can use it to strengthen communication with consumers and persuade them to purchasing certain product or service (Bjelica et al., 2014; Muratović et al., 2014. Hence, there is nececity to analyse their general attitudes among various questions, while this research was aimed at gaining relevant knowledge about the attitudes of Serbian consumers toward advertising through sport among the question how often they participate in sports activities. Methods: The sample included 127 respondents, divided into six subsample groups: consumers who do not participate in sport activities at all, then consumers who participate in sport activities less than ones a month, next 1–4 a month, 5–10 a month, 11–20 a month, as well as consumers participate in sport activities more than 20 times a months. The sample of variables contained the system of three general attitudes which were modeled by seven-point Likert scale. The results of the measuring were analyzed by multivariate analysis (MANOVA and univariate analysis (ANOVA and Post Hoc test. Results: Based on the statistical analyses it was found that significant differences didn’t occur at multivariate level, as well as between all three variables at a significance level of p=.05. Hence, it is interesting to highlight that it was found there are no significant differences showed up between the consumers who participate in various sports activities. Discussion: These results are so important for the marketers, mostly due to the reason they can merge all the potential consumers who participate in various sports activities into one homogenious group. This wasn’t the case in previous investigations (Popović et al., 2011 and this observation presents relevant information.

  13. The effect of knee brace and knee sleeve on the proprioception of the knee in young non-professional healthy sportsmen.

    2013-12-01

    Proprioception has been defined as the capacity to feel the position of a joint in space as sensed by the central nervous system. Prophylactic knee braces are supposed to help in knee injury prevention not just with a mechanical support of the joint but also improving proprioception. The main aim of this study was to determine the effects of a knee brace and a knee sleeve on knee proprioception. The secondary aim was to determine if different starting angles of the knee and different movement directions influence knee proprioception. We tested a group of twenty healthy male sport students without knee injuries. They were tested with the brace, with the sleeve and without support. The threshold of detection of passive knee movement with a starting knee angle of 30° and 60°, both in flexion and extension was determined. We did not find any statistically significant change in the threshold of detection of passive knee movement wearing the brace or the sleeve compared to the unsupported condition (p=0.462, α=0.05). We found a significantly lower proprioceptive sensitivity starting at the more flexed knee angle (p=0.005, α=0.05) and moving in extension than in the other test situations (p=0.001, α=0.05). Movement direction and starting position appear to influence the threshold of detection of passive knee movement. The results of this study also suggest that knee supports do not influence either positively or negatively knee proprioception of uninjured active subjects. Copyright © 2013 Elsevier B.V.

    This study quantified activation of 8 muscles of the shoulder, trunk, and back during standing performance of (a) arm abduction in the plane of the scapula (scaption), (b) proprioceptive neuromuscular facilitation (PNF) diagonal 1 flexion (D1F), and (c) PNF diagonal 2 flexion (D2F) while lifting a dumbbell with the dominant hand. Twelve men (26.1 ± 4.4 years) and 13 women (24.5 ± 1.9 years) volunteered to participate. Electromyographic signals were collected with DE-3.1 double-differential surface electrodes at a sampling frequency of 1,000 Hz. Electromyographic signals were normalized to peak activity in the maximum voluntary isometric contraction (MVIC) trial and expressed as a percentage. One-way repeated-measures analysis of variance with Bonferroni corrections (α = 0.05) examined muscle activation patterns across the 3 conditions. For the middle trapezius, average activation was greater (p 60% MVIC) with the exception of the lower trapezius (55% MVIC). In contrast, erector spinae and external oblique muscles exhibited moderate activation (21-40% MVIC) during arm elevation. The 6 muscles of the shoulder complex displayed high to very high muscle activation at a level appropriate for strength training during all 3 exercise conditions.

    Proprioception is a vital aspect of motor control and when degraded or lost can have a profound impact on function in diverse clinical populations. This systematic review aimed to identify clinically related tools to measure proprioceptive acuity, to classify the construct(s) underpinning the tools, and to report on the clinimetric properties of the tools. We searched key databases with the pertinent search terms, and from an initial list of 935 articles, we identified 57 of relevance. These articles described 32 different tools or methods to quantify proprioception. There was wide variation in methods, the joints able to be tested, and the populations sampled. The predominant construct was active or passive joint position detection, followed by passive motion detection and motion direction discrimination. The clinimetric properties were mostly poorly evaluated or reported. The Rivermead Assessment of Somatosensory Perception was generally considered to be a valid and reliable tool but with low precision; other tools with higher precision are potentially not clinically feasible. Clinicians and clinical researchers can use the summary tables to make more informed decisions about which tool to use to match their predominant requirements. Further discussion and research is needed to produce measures of proprioception that have improved validity and utility. © The Author(s) 2015.

    Although expert groups have developed guidelines for fluid intake during sports, there is debate about their real-world application. We reviewed the literature on self-selected hydration strategies during sporting competitions to determine what is apparently practical and valued by athletes. We found few studies of drinking practices involving elite or highly competitive athletes, even in popular sports. The available literature revealed wide variability in fluid intake and sweat losses across and within different events with varied strategies to allow fluid intake. Typical drinking practices appear to limit body mass (BM) losses to ~2 % in non-elite competitors. There are events, however, in which mean losses are greater, particularly among elite competitors and in hot weather, and evidence that individual participants fail to meet current guidelines by gaining BM or losing >2 % BM over the competition activity. Substantial (>5 %) BM loss is noted in the few studies of elite competitors in endurance and ultra-endurance events; while this may be consistent with winning outcomes, such observations cannot judge whether performance was optimal for that individual. A complex array of factors influence opportunities to drink during continuous competitive activities, many of which are outside the athlete's control: these include event rules and tactics, regulated availability of fluid, need to maintain optimal technique or speed, and gastrointestinal comfort. Therefore, it is questionable, particularly for top competitors, whether drinking can be truly ad libitum (defined as "whenever and in whatever volumes chosen by the athlete"). While there are variable relationships between fluid intake, fluid balance across races, and finishing times, in many situations it appears that top athletes take calculated risks in emphasizing the costs of drinking against the benefits. However, some non-elite competitors may need to be mindful of the disadvantages of drinking beyond

    Several important research questions have been addressed: (1) What are the cross-sectional associations between sports club participation, objectively measured physical activity, and adiposity? (2) Do measures of physical activity and adiposity predict subsequent sports club participation? (3) Does sports club participation predict subsequent measures of physical activity and adiposity? and (4) Do changes in sports club participation predict changes in objective measures of physical activity and adiposity? Longitudinal and cross-sectional. Data from the Gateshead Millennium Study birth cohort (n=609 at age 7 years) were analysed for associations between adiposity, sports club participation and accelerometer-measured physical activity from ages 7y to 9y to 12y. Seventy-two per cent of 9 year olds and 63% of 12 year olds took part in a sports club. Sports club participation was significantly associated with overall accelerometer-measured physical activity at 12y (coefficient=0.0.09; 95% CI: 0.01-0.16) but not 9y. An inverse relationship between fat mass (estimated from bioelectric impedance) and sport club participation, and between fat mass and accelerometer-measured physical activity was observed at 12y, but not 9y. Sports club participation at 9y was highly predictive of participation at 12y. Sports club participation was significantly associated with socioeconomic status; fewer children from poorer areas took part. Sports club participation in adolescence may be associated with decreased levels of adiposity. Furthermore, the potential benefits of sports club participation for adiposity are likely generated from continuous participation in sports, rather than any long-term protective effects.

    Prevention of ankle sprain, the most common sporting injury, is only possible once risk factors have been identified. Voluntary strength, proprioception, postural sway, and range of motion are possible risk factors. A systematic review was carried out to investigate these possiblities. Eligible studies were those with longitudinal design investigating ankle sprain in subjects aged ⩾15 years. The studies had to have measured range of motion, voluntary strength, proprioception, or postural sway...

    Relatively few studies have been reported that document how proprioception varies across the workspace of the human arm. Here we examined proprioceptive function across a horizontal planar workspace, using a new method that avoids active movement and interactions with other sensory modalities. We systematically mapped both proprioceptive acuity (sensitivity to hand position change) and bias (perceived location of the hand), across a horizontal-plane 2D workspace. Proprioception of both the left and right arms was tested at nine workspace locations and in 2 orthogonal directions (left-right and forwards-backwards). Subjects made repeated judgments about the position of their hand with respect to a remembered proprioceptive reference position, while grasping the handle of a robotic linkage that passively moved their hand to each judgement location. To rule out the possibility that the memory component of the proprioceptive testing procedure may have influenced our results, we repeated the procedure in a second experiment using a persistent visual reference position. Both methods resulted in qualitatively similar findings. Proprioception is not uniform across the workspace. Acuity was greater for limb configurations in which the hand was closer to the body, and was greater in a forward-backward direction than in a left-right direction. A robust difference in proprioceptive bias was observed across both experiments. At all workspace locations, the left hand was perceived to be to the left of its actual position, and the right hand was perceived to be to the right of its actual position. Finally, bias was smaller for hand positions closer to the body. The results of this study provide a systematic map of proprioceptive acuity and bias across the workspace of the limb that may be used to augment computational models of sensory-motor control, and to inform clinical assessment of sensory function in patients with sensory-motor deficits.

    As major actors in sports activities, sports coaches can play a significant role in health education and contribute to the psychological well-being of young people. However, not all participants in sports activities experience sports positively, which reduces the potential benefits for health. The present study investigates if coaches' efforts to promote health increase young athletes' enjoyment, self-esteem and perceived health in daily life and decrease sport dropout. To control for the variability between teams and between clubs, multilevel modeling was applied. A sample of 342 young football players completed questionnaires assessing their perceptions of coaches' Health Promotion (HP) activities, enjoyment of sports, dropout intentions, self-esteem and perceived health in daily life. HP general score was positively related to enjoyment and perceived health as well as negatively dropout intentions. Players perceiving their coaches as promoting fair and play (Respect for oneself and others) scored higher on their perceptions of enjoyment in sport, self-esteem and self-reported health, and lower on dropout intentions. Moreover, players recognizing their coaches as encouraging their healthy lifestyle also reported higher perceptions of sport enjoyment, whereas player's perceived coaches' activities on substance use were associated with lower participants' enjoyment. These results support the importance of developing HP in sports clubs. Especially, promoting respect of oneself and others seems to be the more beneficial to sport participants.

    To assess the efficacy of critical metabolic power derived from variable-speed movement for classifying intensity in team sport activity. Elite male hockey players (n = 12) completed a series of time trials (100 yd, 400 yd, 1500 yd) and a 3-min all-out test to derive both critical speed (CS) and critical power (CP). Heart rate (HR), blood lactate (BLa) and rating of perceived exertion (RPE) were measured during each protocol. Participants (n = 10) then played 2 competitive hockey matches. Time spent >85% of HRmax was compared to time spent above CS (from the time trials) and CP (from the 3-min test). Between protocols, there was a moderate and non-significant association for CS (r = 0.359, P = 0.252), and a very large association for CP (r = 0.754, P = 0.005); the association was very large for peak HR (r = 0.866, P 85% HRmax and time spent above both CS (r = 0.719, P < 0.001) and CP (r = 0.867, P < 0.001). This relationship was stronger for CP compared to CS (Z = 3.29, P = 0.0007). Speed is not an appropriate parameter for the classification of team-sport activity comprising continual changes in speed and direction, however, critical metabolic power derived from variable-speed activity appears useful for this purpose.

    Full Text Available Clinicians and researchers often need to measure proprioception (position sense, for example to monitor the progress of disease, to identify the cause of movement or balance problems, or to ascertain the effects of an intervention. While researchers can use sophisticated equipment to estimate proprioceptive acuity with good precision, clinicians lack this option and must rely on the subjective and imprecise methods currently available in the clinic. Here we describe a novel technique that applies psychometric adaptive staircase procedures to hand proprioception with a simple tablet-style apparatus that could easily be adapted for the clinic. We report test-retest reliability, inter-rater reliability, and construct validity of the adaptive staircase method vs. two other methods that are commonly used in clinical settings: passive motion direction discrimination (PMDD and matching. As a first step, we focus on healthy adults. Subjects ages 18-82 had their proprioception measured with each of the three techniques, at the metacarpophalangeal joint in the second finger of the right hand. A subset completed a second session in which the measures were repeated, to assess test-retest reliability. Another subset had the measurements done by two different testers to assess inter-rater reliability. Construct validity was assessed using stepwise regression on age and activity level, and correlations calculated across the three methods. Results suggest that of the three methods, the adaptive staircase method yields the best test-retest reliability, inter-rater reliability, and construct validity. The adaptive staircase method may prove to be a valuable clinical tool where more accurate assessment of proprioception is needed.

    Full Text Available BACKGROUND: An effort to promote participation in any type of PA is more effective when it is aimed at needs, interests and preferences of particular target group. Current evidence emphasizes the insufficiency of PA in all age groups. OBJECTIVE: The purpose of the study was to analyze and describe the structure of sport activity preferences of high school students and to contribute to prospective improvement of sports and physical activity programs. METHODS: Two standardized questionnaires were used – 1. sport preferences questionnaire, 2. international physical activity questionnaire (IPAQ. The research sample (N = 333 consisted of high school students from the Czech Republic. RESULTS: Our results confirm that the differences between girls and boys are not as great as they were few decades ago. There is a visible dynamic in the development of sport preferences structure. Despite this fact there is a spectrum of sports that are constantly preferred – soccer, volleyball, aerobics and swimming. Acquired results indicate that the range of PA amount in girls varies from 2,372 MET-min/week (15 year old girls to 4,467 MET-min/week (17 year old girls, while acquired results in boys varies from 2,535 MET-min/week (16 year old boys to 4,973 MET-min/week (17 year old boys. The results, if properly applied, could increase the total amount of PA in high school students and improve the effectiveness of school PE.

    Full Text Available Exertional heat stroke (EHS is one of the leading causes of sudden death in sport and physical activity. In American Football alone, there have been 46-documented EHS fatalities in the United States between 1995-2010.  In 2003, National Collegiate Athletics Association mandated pre-season heat acclimatization guidelines, which successfully decreased the number of heat stroke fatalities in collegiate American football. However, despite the advancement in modern medical care and increased awareness in heat safety, lack of appropriate on-site medical care is still contributing to EHS seen especially in the youth level. It is well established in scientific literature that fatalities as a result of EHS are largely preventable with proper education on the knowledge of recognition, treatment, and prevention of EHS. This document provides a review of the current best medical practices and evidence on the epidemiology, pathophysiology, risk factors, recognition, treatment, prevention, and return to play recommendations for EHS, specifically as they relate to sport and physical activity.

    The aim was to investigate and compare the effects of proprioceptive neuromuscular facilitation (PNF) and static stretching (SS) on maximal voluntary contraction (MVC) and muscle activation in indoor soccer players. Thirty-three young adult men were divided into two groups: (i) sedentary and (ii) trained. Each group completed three different experimental trials: SS, PNF and no stretching (NS). The MVC of knee extension was evaluated before and immediately after each condition along with electromyography from the vastus lateralis (VL) and rectus femoris (RF) muscles of the dominant leg. PNF or SS techniques induced no decrease on MVC and muscle electromyographical activity in indoor soccer players (P>0·05). The electromyography of the RF and VL was lower after SS only in the sedentary group (P≤0·05). Short-duration PNF or SS has no effect on isometric MVC and muscle activity in indoor soccer players. © 2013 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    Introduction Extracurricular school sports programs can provide adolescents, including those who are economically disadvantaged, with opportunities to engage in physical activity. Although current models favor more exclusionary interscholastic sports, a better understanding is needed of the potential effects of providing alternative school sports options, such as more inclusive intramural sports. The purpose of this study was to simulate the potential effect of implementing intramural sports programs in North Carolina middle schools on both the rates of sports participation and on energy expenditure related to physical activity levels. Methods Simulations were conducted by using a school-level data set developed by integrating data from multiple sources. Baseline rates of sports participation were extrapolated from individual-level data that were based on school-level characteristics. A regression model was estimated by using the simulated baseline school-level sample. Participation rates and related energy expenditure for schools were calculated on the basis of 2 policy change scenarios. Results Currently, 37.2% of school sports participants are economically disadvantaged. Simulations suggested that policy changes to implement intramural sports along with interscholastic sports could result in more than 43,000 new sports participants statewide, of which 64.5% would be economically disadvantaged students. This estimate represents a 36.75% increase in economically disadvantaged participants. Adding intramural sports to existing interscholastic sports programs at all middle schools in North Carolina could have an annual effect of an additional 819,892.65 kilogram calories expended statewide. Conclusion Implementing intramural sports may provide economically disadvantaged students more access to sports, thus reducing disparities in access to school sports while increasing overall physical activity levels among all children.

    The aim of the present study was to compare the acute effects of active (AC), ballistic (BA), passive (PA), proprioceptive neuromuscular facilitation stretching (PNF) methods on performance in vertical jumping, sit and reach, and sprinting in young soccer players. Twelve trained soccer players (17.67 ± 0.87 years) participated in the study. The jump height (H), peak power (PP), and relative power (RP) in the squat jump (SJ) and countermovement jump (CMJ), the range of motion (ROM), the rate of perceived exertion (RPE), and time (s) in 10-20-30 m sprints were evaluated. Significant differences (p <0.05) in H were found in the comparisons between the PA and control condition (CO) for the SJ. For the CMJ, differences in H were observed between the PA and CO, and PNF with CO and BA, and in the PP between the PNF and CO, AC, and BA, as well as in the RP between the PNF and BA. Significant increases in ROM were found in the AC, BA, PA, and PNF, compared to the CO. In relation to RPE, higher scores were reported in the PA and PNF conditions compared to the AC and BA. No significant differences were found in 10-20-30 m sprints. Therefore, the AC and BA methods can be used prior to vertical jump and sprint activities, with the aim of increasing flexibility. However, the PA and PNF methods should be avoided, due to subsequent negative effects on vertical jump performance.

Randomized controlled trial. Rehabilitation clinics. A total of 53 participants with chronic low back pain were randomized into the CORE group and the control group. CORE group participants underwent the 30-minute CORE programme, five times per week, for eight weeks, with additional use of hot-packs and transcutaneous electrical nerve stimulation, while the control group used only hot-packs and transcutaneous electrical nerve stimulation. Participants were evaluated pretest, posttest, and two months after the intervention period to measure resting and movement-induced pain, pressure pain as secondary pain, active range of pain-free motion, and trunk proprioception. Pain intensity at rest (35.6 ±5.9 mm) and during movement (39.4 ±9.1 mm) was significantly decreased in the CORE group following intervention compared with the control group.

Questions about satisfaction with physical activity, participation in organized physical activity and competitions, or watching competitions were asked. Two EUROFIT tests were used, the 20-m endurance shuttle-run and sit-and-reach, plus the sum of 9 skinfold thicknesses. Children who participated in organized physical activity and in competitions had a higher Physical Activity Index. Passive watching of competitions was not related to children's physical activity or their perceived or measured motor abilities.

    Research suggests participation in youth sport does not guarantee physical activity (PA) guidelines are met. Studies indicate few children achieve recommended levels of moderate-to-vigorous physical activity (MVPA) during their youth sport involvement, and habitual levels of MVPA are below the recommended 60 min per day. Informed by self-determination theory, this study examined whether the coach-created social environment and related player motivation predict variability in objectively measured MVPA within the youth sport setting. Seventy three male youth sport footballers (Mean age = 11.66 ± 1.62) completed a multisection questionnaire assessing their perceptions of the social environment created in youth sport (autonomy supportive and controlling) and motivation towards their football participation (autonomous and controlled). Intensity of PA during youth sport was measured using accelerometers (GT3X, ActiGraph). Results supported a model in which perceptions of autonomy support significantly and positively predicted autonomous motivation towards football, which in turn significantly and positively predicted youth sport MVPA (% time). A significant indirect effect was observed for perceptions of autonomy support on youth sport %MVPA via autonomous motivation. Results have implications for optimising MVPA engagement during youth sport and increasing daily MVPA towards recommended and health-enhancing levels on youth sport days.

    The accommodation of 324 school children aged 10 to 16 years was studied before and after a 12-minute reading session. One hundred and twenty children (81 girls and 39 boys) were wind instrument players in school bands, 93 children (48 girls and 45 boys) trained in an individual sport, and 111 children (65 girls and 46 boys) having no such activities were studied as a control group. At the end of the reading session, decreased accommodation (7 diopters or less) was found in 19 (15.8%) of the musicians, in six (6.5%) of the athletes, and in six (5.4%) of the control group. The difference was significant between the musicians and the control group, but not significant between the athletes and the control group. The majority of the children with low accommodation were girls; there was only one boy with decreased accommodation in each of the three groups.

    Neurological injuries such as stroke can lead to proprioceptive impairment. For an informed diagnosis, prognosis, and treatment planning, it is essential to be able to distinguish between healthy performance and deficits following the neurological injury. Since there is some evidence that proprioception declines with age and stroke occurs predominantly in the elderly population, it is important to create a healthy reference model in this specific age group. However, most studies investigate age effects by comparing young and elderly subjects and do not provide a model within a target age range. Moreover, despite the functional relevance of the hand in activities of daily living, age-based models of distal proprioception are scarce. Here, we present a proprioception model based on the assessment of the metacarpophalangeal joint angle difference threshold in 30 healthy elderly subjects, aged 55-80 years (median: 63, interquartile range: 58-66), using a robotic tool to apply passive flexion-extension movements to the index finger. A two-alternative forced-choice paradigm combined with an adaptive algorithm to define stimulus magnitude was used. The mixed-effects model analysis revealed that aging has a significant, increasing effect on the difference threshold at the metacarpophalangeal joint, whereas other predictors (eg, tested hand or sex) did not show a significant effect. The adaptive algorithm allowed reaching an average assessment duration proprioception at the level of the hand. The established age-based model of proprioception in elderly may serve as a reference model for the proprioceptive performance of stroke patients, or of any other patient group with central or peripheral proprioceptive impairments. Furthermore, it demonstrates the potential of such automated robotic tools as a rapid and quantitative assessment to be used in research and clinical settings.

  2. Role of genetic markers in sport and recreational physical activity

    Full Text Available The genetic and environmental factors and their interaction contribute to sports performance. So far, it has been identified a large number of genetic markers associated with sports performance and risk of sports injuries. Sports genomics is a relatively young scientific discipline and the necessary additional complex research on a large number of participants is required before scientific results in this field could be applicable in practice. At present, the application of tests based on genetic information for sport talent identification or recommendations for personalized training, in order to achieve optimal sport performance, is not scientifically justified. It is also necessary to carefully consider all the ethical issues related to such testing in children.

    To compare the immediate and medium-term effects of three stretching methods on the knee flexion range in people with a total knee replacement. Randomized clinical trial. Rehabilitation hospital. 117 patients were recruited and 100 (mean age: 68.43 ± 7.95 years) of them completed the study. Patients receiving total knee replacement due to knee osteoarthritis were randomly assigned into 3 groups of: active stretching (group 1, n =32), passive stretching (group 2, n =35) and proprioceptive neuromuscular facilitation stretching (group 3, n =33). The immediate change in both active and passive knee flexion range after the first treatment session and the pattern of change in these ranges throughout the 2-week study period were compared among the three groups. All groups demonstrated significant improvement in knee ranges with time. The active range of group 1 improved by 19.9°, group 2 by 25.3° and group 3 by 22.5° throughout the 2-week period, whereas the improvements in the passive range were 18.8°, 24.5° and 22.7°, respectively. For between-group comparisons, no significant difference was found in both active (P = 0.647) and passive (P = 0.501) knee range immediately after stretching. For the changes at 2 weeks, there was also no significant difference among the groups in both active (P = 0.716) and passive (P = 0.959) knee ranges. This study revealed that all three modes of stretching were associated with an increase in the knee flexion range of patients after total knee replacement, with no statistically significant differences between the changes seen.

    Full Text Available Abstract Background The purpose of this paper is to review relationships of academic performance and some of its determinants to participation in school-based physical activities, including physical education (PE, free school physical activity (PA and school sports. Methods Linkages between academic achievement and involvement in PE, school PA and sport programmes have been examined, based on a systematic review of currently available literature, including a comprehensive search of MEDLINE (1966 to 2007, PSYCHINFO (1974 to 2007, SCHOLAR.GOOGLE.COM, and ERIC databases. Results Quasi-experimental data indicate that allocating up to an additional hour per day of curricular time to PA programmes does not affect the academic performance of primary school students negatively, even though the time allocated to other subjects usually shows a corresponding reduction. An additional curricular emphasis on PE may result in small absolute gains in grade point average (GPA, and such findings strongly suggest a relative increase in performance per unit of academic teaching time. Further, the overwhelmingly majority of such programmes have demonstrated an improvement in some measures of physical fitness (PF. Cross-sectional observations show a positive association between academic performance and PA, but PF does not seem to show such an association. PA has positive influences on concentration, memory and classroom behaviour. Data from quasi-experimental studies find support in mechanistic experiments on cognitive function, pointing to a positive relationship between PA and intellectual performance. Conclusion Given competent providers, PA can be added to the school curriculum by taking time from other subjects without risk of hindering student academic achievement. On the other hand, adding time to "academic" or "curricular" subjects by taking time from physical education programmes does not enhance grades in these subjects and may be detrimental to health.

    The aim of this study was to provide initial evidence of validity and reliability of scores derived from the Activity Context in Youth Sport Questionnaire (ACYSQ), an instrument designed to offer a comprehensive assessment of the activities adolescents take part in during sport practices. Two studies were designed for the purposes of item development and selection, and to provide evidence of structural and criterion validity of ACYSQ scores, respectively (N = 334; M age = 14.93, SD = 1.76 years). Confirmatory factor analysis (CFA) supported the adequacy of a 20-item ACYSQ measurement model, which was invariant across gender, and comprised the following dimensions: (1) stimulation; (2) usefulness-value; (3) authenticity; (4) repetition-boredom; and (5) ineffectiveness. Internal consistency reliability estimates and composite reliability estimates for ACYSQ subscale scores ranged from 0.72 to 0.91. In regression analyses, stimulation predicted enjoyment and perceived competence, ineffectiveness was significantly associated with perceived competence and authenticity emerged as a predictor of commitment in sport. These findings indicate that the ACYSQ displays adequate psychometric properties and the use of the instrument may be useful for studying selected activity-based features of the practice environment and their motivational consequences in youth sport.

    The present study asses the prevalence of depressive symptoms among college students in Split, Croatia, and positive influence of sport activity on decreasing the depression symptoms. Authors screened all 664 college students of the first year of study. All of them were over the 18 years and the mean age was 19.4 +/- 1.2 years. There were 466 females (70.2%) and 178 (26.8%) males. They answered The Beck Depression Inventory (BDI) and questionnaire about their sport activity (no sport activity, recreational and active in sports). For the purpose of the analysis depressive symptoms were defined as a score of > 11. Chi-square and Mann-Whitney test were used for data analysis. 9.4% of the students had significant depression symptoms (score > 11). No one student had score > 26 (symptoms of major depression). Statistically significant lower score on BDI have students who are active in sports (score median = 3) compared to group of recreational (score median = 4) and in correlation to group who are not active in sports (score median = 5) (Kruskal-Wallis: p depressions symptoms, while in the group of non active in sports (N = 60) are 18 depressive (chi2-test: p = 0,005). Females are statistically more depressed than males (chi2-test: p = 0.01). In the female group 49 (10.5%) are depressed, and in the male group are 9 (5%). Compared to gender in separate analysis we did not find correlation of decreasing depression symptoms and sport activity among males (chi2-test: p = 0.47), while in females we find that sport activity has significant effect (chi2-test: p = 0.026). Our results shoved moderate values of depression symptoms among college population in Split, Croatia. More females than males experienced depressive symptoms. While sport activity did not have significant influence on the depression in male population, it has significant influence in reducing the depression symptoms among females.

    2015-01-01

    Understanding factors that influence throwing speed and accuracy is critical to performance in baseball. Shoulder proprioception has been implicated in the injury risk of throwing athletes, but no such link has been established with performance outcomes. The purpose of this study was to describe any relationship between shoulder proprioception acuity and throwing speed or accuracy. Twenty healthy elite adolescent male baseball players (age, 19.6 ± 2.6 years), who had represented the state of New South Wales in the past 18 months, were assessed for bilateral active shoulder proprioception (shoulder rotation in 90° of arm abduction moving toward external rotation using the active movement extent discrimination apparatus), maximal throwing speed (MTS, meters per second measured via a radar gun), and accuracy (total error in centimeters determined by video analysis) at 80 and 100% of MTS. Although proprioception in the dominant and nondominant arms was significantly correlated with each other (r = 0.54, p proprioception and performance. Shoulder proprioception was not a significant determinant of throwing performance such that high levels of speed and accuracy were achieved without a high degree of proprioception. There is no evidence to suggest therefore that this particular method of shoulder proprioception measurement should be implemented in clinical practice. Consequently, clinicians are encouraged to consider proprioception throughout the entire kinetic chain rather than the shoulder joint in isolation as a determining factor of performance in throwing athletes.

    Maintenance of motor activity by autonomic nervous system is adjusted, mainly, by congenital reflexes. But alongside with inborn reactions to muscular work at formation of motor skill the specific vegetative components are formed to the given kind of sport activity. The aim of our research was revealing those physiological features which are characteristic for an organism of the high skilled sportsmen, with large experience of training and competitive activity. At tested football players have been measured some parameters of external respiration and cardiovascular system. In our investigation it is shown, that programming of the same productivity of work and the same effect are achieved by unequal vegetative support and a different combination of separate components of the general vegetative reaction. Definition and a due estimation of these intermediate parameters in conditions of rest and at physical loading enables objective judgement about a functional condition of the sportsman, about weak parts in system of maintenance of a homeostasis of an organism and directions of accomplish the functioning of the basic effectors.

    Overweight and obesity in Australia is an emerging health concern. Obesity prevention initiatives must consider both physical activity and nutrition to be effective. Community sports venues have the capacity to promote healthy lifestyles through physical activity as well as healthy food choices. A telephone survey was conducted on parents of children aged 5-17 years in NSW to determine the nature of food and beverages purchased by children at community sporting venues and to determine parent's perception of the role that government should play in regulating the types of food and beverages sold at these outlets. The majority of canteens at children's sporting venues were considered to sell mostly unhealthy food and beverages (53%). Very few parents reported that canteens sold mostly healthy food and beverages. Parents reported that their child's most frequently purchased food and beverage items at outdoor sports fields were water, chocolate and confectionery, soft drink and sports drinks, and ice cream. At community swimming pools the most frequently purchased items were ice cream, followed by snack foods, including chips, cakes and biscuits. Most parents (63%) agreed that government should restrict the types of food and beverages that can be sold at children's sporting venues. Children are receiving inconsistent health messages at sporting venues, with healthy lifestyles being promoted through sports participation, but unhealthy dietary choices being provided at sports canteens.

  16. Wrist proprioception: amplitude or position coding?

    2016-10-01

    Full Text Available This work examines physiological mechanisms underlying the position sense of the wrist, namely the codification of proprioceptive information related to pointing movements of the wrist towards kinesthetic targets. Twenty-four healthy subjects participated to a robot-aided assessment of their wrist proprioceptive acuity to investigate if the sensorimotor transformation involved in matching targets located by proprioceptive receptors relies on amplitude or positional cues. A joint position matching test was performed in order to explore such dichotomy. In this test, the wrist of a blindfolded participant is passively moved by a robotic device to a preset target position and, after a removal movement from this position, the participant has to actively replicate and match it as accurately as possible. The test involved two separate conditions: in the first the matching movements started from the same initial location; in the second one the initial location was randomly assigned. Target matching accuracy, precision and bias in the two conditions were then compared. Overall results showed a consistent higher performance in the former condition than in the latter, thus supporting the hypothesis that the joint position sense is based on vectorial or amplitude coding rather than positional.

    Proprioceptive mechanoreceptors provide neural feedback for position in space and are critical for three-dimensional interaction. Proprioception is decreased with osteoarthritis of the knees, which leads to increased risk of falling. As the prevalence of osteoarthritis increases so does the need for total knee arthroplasty (TKA), and knowing the effect of TKA on proprioception is essential. This article reviews the literature regarding proprioception and its relationship to balance, aging, osteoarthritis, and the effect of TKA on proprioception. Knee arthroplasty involving retention of the cruciate ligaments is also reviewed, as well the evidence of proprioception in the posterior cruciate ligament after TKA. Copyright © 2016 Elsevier Inc.

  4. Three people can synchronize as coupled oscillators during sports activities.

    2011-10-01

    Full Text Available We experimentally investigated the synchronized patterns of three people during sports activities and found that the activity corresponded to spatiotemporal patterns in rings of coupled biological oscillators derived from symmetric Hopf bifurcation theory, which is based on group theory. This theory can provide catalogs of possible generic spatiotemporal patterns irrespective of their internal models. Instead, they are simply based on the geometrical symmetries of the systems. We predicted the synchronization patterns of rings of three coupled oscillators as trajectories on the phase plane. The interactions among three people during a 3 vs. 1 ball possession task were plotted on the phase plane. We then demonstrated that two patterns conformed to two of the three patterns predicted by the theory. One of these patterns was a rotation pattern (R in which phase differences between adjacent oscillators were almost 2π/3. The other was a partial anti-phase pattern (PA in which the two oscillators were anti-phase and the third oscillator frequency was dead. These results suggested that symmetric Hopf bifurcation theory could be used to understand synchronization phenomena among three people who communicate via perceptual information, not just physically connected systems such as slime molds, chemical reactions, and animal gaits. In addition, the skill level in human synchronization may play the role of the bifurcation parameter.

    AIM: The main aim of this study was to examine differences in sport participation motives, the frequency of engaging in sports activities according to gender, region and field of study, but also the association between the incidence of engaging in sports activity and the motivation for sports activity of students at the University of Ljubljana. MATERIAL AND METHODS: Five thousand two hundred seventy-one students completed The Exercise Motivations Inventory (EMI-2), with additional questions about 12 socio-demographic parameters. RESULTS: The results reveal that most of the students are engaged in unorganized sports activities. Male students engage in sports activity more often than female students do. For male students, dominant participation motives are enjoyment, challenge, social recognition, affiliation, competition and strength but also endurance, for female students these are: stress and weight management, revitalisation, ill-health avoidance, positive health, appearance and nimbleness. Gender differences in participation motives are partly reflected also in differences according to the field of study. The correlations between the frequency of engaging in sports activity and the participation motives are mainly statistically significant. We did not find any significant differences in participation motives by region. CONCLUSION: In spite of these discouraging findings, increasing physical activity among students continues to be a national priority. PMID:29104693

    The main aim of this study was to examine differences in sport participation motives, the frequency of engaging in sports activities according to gender, region and field of study, but also the association between the incidence of engaging in sports activity and the motivation for sports activity of students at the University of Ljubljana. Five thousand two hundred seventy-one students completed The Exercise Motivations Inventory (EMI-2), with additional questions about 12 socio-demographic parameters. The results reveal that most of the students are engaged in unorganized sports activities. Male students engage in sports activity more often than female students do.

Gender differences in participation motives are partly reflected also in differences according to the field of study. The correlations between the frequency of engaging in sports activity and the participation motives are mainly statistically significant. We did not find any significant differences in participation motives by region. In spite of these discouraging findings, increasing physical activity among students continues to be a national priority.

    To examine how social support, participation in intramurals, varsity and community sports are associated with physical activity among Ontario secondary school students, and explore gender differences in the prevalence of physical activity and participation in school- and community-based sports. Data from 25,416 students (grades 9-12) attending 76 Ontario secondary schools were collected using the School Health Action, Planning, and Evaluation System (SHAPES). Logistic regression analyses examined how social support and school- and community-based sports participation were associated with physical activity. Males and females with low social support for physical activity were less likely to be active than their lower-risk peers (males: OR 0.61; females: OR 0.72). Males and females were more likely to be active if they participated in intramural activities (males: OR 1.92; females: OR 1.55), varsity sports (males: OR 1.93; females: OR 1.77), or community sports (males: OR 2.84; females: OR 2.90). Since students with low social support for physical activity were less likely to be active, interventions to increase support and engagement in physical activity should be targeted to these students. In addition, considering that participation in school- and community-based sports increases the likelihood that students were active, practitioners should seek to enhance opportunities for participation in and access to these programs in order to increase the level of activity obtained by students.

    The role of sports in decreasing the prevalence of many diseases has led to a growing interest in the field of sport and exercise medicine. But sport and exercise medicine still remains new to the Arab world, waiting to be explored. The aim of this study is to describe and characterise sport and exercise medicine research activity in the Arab world between 2002 and 2016. The PubMed database was used to search for publications related to sport and exercise medicine. Publications were classified according to the country of origin and filtered to include publications between 2002 and 2016. Research output was analysed with respect to gross domestic product (GDP) and population of each country. A total of 1148 papers related to sport and exercise medicine were found to be published in the Arab countries between 2002 and 2016. Sport-and-exercise-medicine-related publications constituted 0.86% of the total biomedical research papers published in the Arab world and 0.49% of the world's sport and exercise medicine literature. The number of sport-and-exercise-medicine-related publications per country ranged from zero to 352, with Qatar occupying the top spot. Tunisia ranked first with respect to publications per average GDP, while Qatar ranked first with respect to publications per average population. Comoros, Mauritania, Somalia, Sudan and Yemen were found to have no publications related to sport and exercise medicine. Sport and exercise medicine is a novel field in the Arab world. Recognising the barriers facing sport and exercise medicine research and exploring them meticulously remains an essential part of the plan to improve the Arab world's output and contribution in this field.

    Full Text Available The purpose of this study was to examine the participation motives of youth from different sport branches and examine the differences with respect to different demographic variables. The study was conducted on 85 girls and 202 boys from different sport branches in Turkey. The average age of the participants were 14.29 years (SD=1.1. The “Participation Motivation Questionnaire (PMQ” (Gill, Gross and Huddleston (1983 was administered on the participants. The reliability and validity of the PMQ was tested by Oyar, Aşçı, Çelebi and Mülazımoğlu (2001. The scale consisted of 30 items and 8 subscales. All items were measured and sorted using a three-point Likert scale. Descriptive statistics and were performed on all variables including means and standard deviations. Independent Samples t-test was also used to determine differences between the scores acquired from the scale and some independent variables. Analysis indicated significant differences in achievement/status (t= 2.71; p < 0.05, team affiliation (t= 2.12; p < 0.05 and friendship (t= 3.81; p < 0.01 subscales between girls and boys. Boys had higher scores than the girls. There were significant differences in achievement/status (t= 2.52; p < 0.01, team affiliation (t= 2.33; p < 0.01, energy release/fitness (t= 2.33; p < 0.05 and competition (t= 2.50; p < 0.01 subscales with regard to sport experience. Less experienced participants had lower scores than the more experienced. As a result, it can be concluded that based on the mean ratings of each of the 30 participation motives, “improve my skills” and “to raise my sport branch” were the most important participation motives for the participants.

    Human proprioception is essential for motor control, yet its central processing is still debated. Previous studies of passive movements and illusory vibration have reported inconsistent activation patterns related to proprioception, particularly in high-order sensorimotor cortices. We investigated brain activation specific to proprioception, its laterality, and changes following stroke. Twelve healthy and three stroke-affected individuals with proprioceptive deficits participated. Proprioception was assessed clinically with the Wrist Position Sense Test, and participants underwent functional magnetic resonance imaging scanning. An event-related study design was used, where each proprioceptive stimulus of passive wrist movement was followed by a motor response of mirror ­copying with the other wrist. Left (LWP) and right (RWP) wrist proprioception were tested separately. Laterality indices (LIs) were calculated for the main cortical regions activated during proprioception. We found proprioception-related brain activation in high-order sensorimotor cortices in healthy participants especially in the supramarginal gyrus (SMG LWP z = 4.51, RWP z = 4.24) and the dorsal premotor cortex (PMd LWP z = 4.10, RWP z = 3.93). Right hemispheric dominance was observed in the SMG (LI LWP mean 0.41, SD 0.22; RWP 0.29, SD 0.20), and to a lesser degree in the PMd (LI LWP 0.34, SD 0.17; RWP 0.13, SD 0.25). In stroke-affected participants, the main difference in proprioception-related brain activation was reduced laterality in the right SMG. Our findings indicate that the SMG and PMd play a key role in proprioception probably due to their role in spatial processing and motor control, respectively. The findings from stroke-­affected individuals suggest that decreased right SMG function may be associated with decreased proprioception. We recommend that clinicians pay particular attention to the assessment and rehabilitation of proprioception following right hemispheric

    To evaluate the prevalence of urinary stress incontinence (USI) in menstruating women practising recreational sports activity, to detect specific sports with a stronger association with urinary incontinence (UI) and to evaluate risk factors possibly related to this condition. Epidemiological study. Non-competitive sports organisations in the province of Varese, Italy. 679 women of fertile age, practising recreational sports activity. Anonymous questionnaire on UI. The questionnaire included questions about patients' general characteristics, occurrence of UI in relation to sport or daily general activities, time of onset of this condition, frequency of leakage episodes, correlation of incontinence with types of movements or sports, subjective impression of being limited on such occasions and/or necessity to modify the type of sport. UI was reported by 101 women (14.9%). Of these, 32 (31.7%) complained of UI only during sports activity, 48 (47.5%) only during daily life and 21 (20.8%) in both circumstances. Body mass index and parity were significantly associated with the risk of UI. Looking at the different sports activities, a higher rate of incontinence was found in women participating in basketball (16.6%), athletics (15%), and tennis or squash (11%). 10.4% of women abandoned their favourite sport, because of USI, and a further 20% limited the way they practised their favourite sport to reduce leakage episodes. Female UI affects a significant proportion of young women practising non-competitive sports activity; it can cause abandonment of the sport or limitation of its practice.

    We examined the demographic, medical and behavioral correlates of participation and interest in extreme sport/adventure activities (ESAA) in gynecologic cancer survivors. A random sample of 621 gynecologic cancer survivors in Alberta, Canada, completed a mailed self-report questionnaire assessing medical, demographic, and behavioral variables and participation and interest in ESAA. Multivariate analyses revealed that gynecologic cancer survivors were more likely to participate in ESAA if they met aerobic exercise guidelines (OR=1.75 [95%CI:1.02-2.99]), had better general health (OR=1.71 [95%CI: 1.01-2.90]), had cervical or ovarian cancer (OR=1.95 [95%CI:0.97-3.93]), were employed (OR=1.71 [95%CI:0.95-3.08]), and were of healthy weight (OR=1.58 [95%CI:0.93-2.68]). Moreover, gynecologic cancer survivors were more likely to be interested in trying an ESAA if they had cervical or ovarian cancer (OR=1.76 [95%CI:0.94-3.27]) and were meeting the strength exercise guidelines (OR=1.68 [95%CI:0.95-2.98]). Medical, demographic, and behavioral variables correlate with participation and interest in ESAA in gynecologic cancer survivors. The pattern of correlates suggests that gynecologic cancer survivors are more likely to participate in ESSA if they have the physical capability and financial resources. Interventions to promote ESAA in gynecologic cancer survivors need to address these 2 key barriers.

    We re-examined children who had previously been declared eligible to participate in competitive sports activities for cardiac disorders, using cardiac investigation protocol. Total of 250 children (224 males [89.6%], and 26 females [10.4%]) between the ages of 8 and 17 years who had just started or were already engaged in sports activities were included in the study. Participants had detailed physical examination evaluated by a pediatric cardiologist. Those with findings suggesting cardiac disorder in their history and/or physical examinations, and/or 12-channel electrocardiography (ECG) were examined with echocardiography (ECHO), 24-hour Holter monitoring, and exercise test. Mean duration of participation in sports activities was 13 months. Among all, 10.4% of the children had abnormalities on ECG. ECHO demonstrated cardiomyopathy in 1, mitral valve prolapse in 2, tricuspid insufficiency in 2, and mitral insufficiency in 1 participant. Holter monitoring revealed non-sustained ventricular tachycardia attacks in 1, and supraventricular tachycardia in another child. Three were ultimately disqualified from partaking in competitive sports. Sports and medical communities must work together to establish study protocols to prevent sudden death related to sports and to make these activities safer for athletes. Pediatric cardiology consultation for young athletes before they start sports activities is needed.

    Full Text Available The main purpose of this research was to analyse the gender differences among students at the University of Ljubljana concerning the popularity of sports and participation in different types and modes of sport activities. The research was done in the 2013 academic year on a random sample of 3% of the students (N=1390. A questionnaire about students’ lifestyles was used (Majerič, 2013. In this study, two variables were analysed: the popularity of different sport activities, and different types and modes of sport activities. The data of the variables were analysed with SPSS for Windows. The basic statistical parameters for both variables were calculated. To calculate the gender differences, a t-test for independent samples and a Mann-Whitney U test were run. An analysis of the popularity of different sport activities showed that gender differences were statistically significant in jogging (p=0.000, walking (p=0.000, football (p=0.000, basketball (p=0.000, fitness (p=0.001, aerobics (p=0.002, and dance activities (p=0.009. Analysis of the types and modes of sport activities among students showed that 63.90% of male students and 68.10% of female students were engaged in unorganized types of sport. Gender differences were found to be statistically significant in two types of sport activities: engaged organized in clubs–competitive out of faculty (p=0.000 and engaged in sport organized at the faculty–competitive (p=0.000. Our findings and conclusions provide useful guidance for the closer and wider professional public.

    Wireless inertial sensors enable quantified feedback, which can be applied to evaluate the efficacy of therapy and rehabilitation. In particular eccentric training promotes a beneficial rehabilitation and strength training strategy. Virtual Proprioception for eccentric training applies real-time feedback from a wireless gyroscope platform enabled through a software application for a smartphone. Virtual Proprioception for eccentric training is applied to the eccentric phase of a biceps brachii strength training and contrasted to a biceps brachii strength training scenario without feedback. During the operation of Virtual Proprioception for eccentric training the intent is to not exceed a prescribed gyroscope signal threshold based on the real-time presentation of the gyroscope signal, in order to promote the eccentric aspect of the strength training endeavor. The experimental trial data is transmitted wireless through connectivity to the Internet as an email attachment for remote post-processing. A feature set is derived from the gyroscope signal for machine learning classification of the two scenarios of Virtual Proprioception real-time feedback for eccentric training and eccentric training without feedback. Considerable classification accuracy is achieved through the application of a multilayer perceptron neural network for distinguishing between the Virtual Proprioception real-time feedback for eccentric training and eccentric training without feedback.

    The primary aim of this study is to investigate the effect of the use of a patellar strap on knee joint proprioception in both healthy participants and in patients with patellar tendinopathy (PT). Secondary aims are to examine whether there is a difference in effectiveness of the use of a patellar strap between participants with low and high proprioceptive acuity and if possible predictors of effectiveness can be determined. Case-control. The threshold to detect passive motion with and without a patellar strap was assessed in 22 healthy participants and 21 unilateral PT patients. The results from the mixed model analysis show that in both groups of participants a small but statistically significant improvement in proprioception was found, primarily in those who had low proprioceptive acuity. A notable finding was that in the symptomatic leg of the PT group no improvement in proprioception by wearing a strap could be determined. Male gender and having fewer symptoms were possible predictors of effectiveness in PT patients. As proprioception plays a role in optimising movements and reducing load to joint-related structures like tendons and ligaments, it is considered an important protection mechanism. Although the improvements in proprioception as a result of wearing the strap are small, it might be that the use of a patellar strap can potentially play a role in injury prevention since poor proprioception can be a risk factor for (re)-injury.

    Full Text Available Sufficient and regular physical activity is considered a protective factor, reducing the onset of secondary disability conditions in adolescents with chronic diseases and functional limitations. The aim of this study was to explore whether participation in organized sport may be associated to higher levels of physical activity in adolescents with functional limitations, based on a national representative sample. Data from the Health Behaviour in School-aged Children (HBSC study collected in Finland from two data collection rounds (2002 and 2010 were conducted and pooled from adolescents aged between 13 and 15 years old with functional limitations (n = 1041. Differences in self-reported physical activity over the past week and participation in organized sport activity were analysed for each function. Overall, four in ten (n = 413 participated in organized sport and were significantly (p < 0.001 more physically active (mean = 4.92days, SD = 1.81 than their non-participating (mean = 3.29, SD = 1.86 peers with functional limitations. Despite low population prevalence, adolescents with epilepsy or visual impairments were the least active if they were not participating in organized sport, yet were the most active if they were involved in organized sport. Participating in organized sport appears to be an important factor promoting resources for maintaining recommended levels of physical activity in Finnish adolescents with functional limitations.

    This microeconometric study analyzes the effects of individual leisure sports participation on long-term labour market variables, health and subjective well-being indicators for West Germany based on individual data from the German Socio-Economic Panel study (GSOEP) 1984-2006. Econometric problems due to individuals choosing their own level of sports activities are tackled by combining informative data and flexible semiparametric estimation methods with a specific way to use the panel dimension of the data. The paper shows that sports activities have sizeable positive long-term labour market effects in terms of earnings and wages, as well as positive effects on health and subjective well-being.

    2017-09-01

    To date, studies examining physical activity (PA) levels have largely been dedicated to the school setting, while there is little known about the activity levels of children who participate in traditional or summer day camps. Participants were 83 11- to 12-year-old campers who partook in either Sport Education or traditional instruction at a large residential summer camp. All lessons were video recorded and coded using the System for Observing Fitness Instruction Time (SOFIT), which categorizes PA levels as well as contextual characteristics. Results indicated that campers who participated in Sport Education spent a higher percentage of time (61.6%) engaged in moderate to vigorous activity than campers in the traditional activity unit (42.2%). In addition, campers spent less time idly within Sport Education (27.9%), than its counterpart (39.5%). These findings indicate that utilizing the Sport Education model may provide campers with higher levels of PA within this context.

    The contribution of sports related factors to predicting long-term physical activity (PA) are unclear. The purpose of this study is to examine tracking of PA during key transition periods in youth and to determine the longitudinal associations between sports club participation and PA. Participants (n = 873, baseline age 10 to 18 years) completed self-report surveys in 2009 and 2014 that included the PACE+ PA tool and sports club participation questions. Spearman correlations assessed PA tracking. ANCOVA analyses examined predictors (sports participation at baseline) of PA (follow-up), adjusting for (a) age and sex; and (b) age, sex, and baseline PA. Tracking of PA was weak-to-moderate (ρ = .16 to .47). Greater sports participation frequency at baseline significantly predicted PA at follow-up (P sports at an elite level had a medium-to-large effect on PA levels 5 years later [d = .75 adjusting for (a); d = .60 adjusting for (b)]. PA should be promoted in youth as tracking coefficients suggest it can, to an extent, continue into later life. The standard achieved in sport has a role in predicting later PA. PA promotion strategies should include frequent, high quality opportunities for sports participation.

    This study described how the Dutch and Canadian governments promote high performance sports, recreational sports, and physical activity (PA) among adults with disabilities on a national level. An internet-based study was conducted to identify and select relevant documents and websites containing information about the national approach to promote disability sports and physical activities in the Netherlands and Canada. Both governments promote high performance sports in similar ways, but use different strategies to promote recreational sports and physical activities. The Dutch approach is characterized by using time-limited programs focusing on enhancement of sports infrastructure and inter-sector collaboration in which municipalities have key roles. The Canadian government promotes recreational sports in disabled populations by supporting programs via bilateral agreements with provinces and territories. Furthermore, the level of integration of disability sports into mainstream sports differs between countries. The findings of this study may inspire policy makers from different countries to learn from one another's policies in order to optimize national approaches to promote disability sports and PA on all levels. Implications for rehabilitation It is recommended for policy makers of national governments to develop and implement policy programs that promote sports and physical activities among people with disabilities because of its potential impact on functioning, participation, quality of life, and health. Insight into national approaches to promote sport and physical activities is relevant for rehabilitation practice to understand ongoing opportunities for people with disabilities to stay physically active after rehabilitation through participation in home and/or community-based sport and physical activities. It seems worthwhile to integrate activities to promote sport and physical activities in rehabilitation in such a way that it fits with the current

  6. Proprioceptive information processing in schizophrenia

    Arnfred, Sidse M H

    Rado (1890-1972) suggested that one of two un-reducible deficits in schizophrenia was a disorder of proprioception. Exploration of proprioceptive information processing is possible through the measurement of evoked and event related potentials. Event related EEG can be analyzed as conventional time...... of the left somatosensory cortex and it was suggested to be in accordance with two theories of schizophrenic information processing: the theory of deficiency of corollary discharge and the theory of weakening of the influence of past regularities. No gating deficiency was observed and the imprecision...... and amplitude attenuation was not a general phenomenon across the entire brain response. Summing up, in support of Rado's hypothesis, schizophrenia spectrum patients demonstrated abnormalities in proprioceptive information processing. Future work needs to extend the findings in larger un-medicated, non...

    Full Text Available Sport and related physical activity education are not being employed in the best possible ways in the developed world because the decision-makers in society don’t truly understand the situation. Illogically, people of all ages in the developed world are not getting sufficient physical activity, whereas those in the undeveloped world are getting too much! In addition, the author questions the vast overemphasis on highly competitive sport at the various levels including the Olympic Games. Further, the situation for the majority of “special-needs” people is poor including those who are exploited by sport competition overemphasis. Six different types of selected competencies are recommended for all children and youth within the educational-system experience. Finally, the author asks five specific questions that should be considered as we seek to improve the overall situation. Keywords: sport and physical activity education, memes, the Olympic Games

    Study Design Controlled laboratory study, cross-sectional. Background Deficits in ankle proprioceptive acuity have been reported in persons with functional instability of the ankle. Passive stiffness has been proposed as a possible mechanism underlying proprioceptive acuity. Objective To compare proprioceptive acuity and passive ankle stiffness in persons with and without functional ankle instability, and to assess the influence of passive joint stiffness on proprioceptive acuity in persons with functional ankle instability. Methods A sample of 18 subjects with and 18 without complaints of functional ankle instability following lateral ankle sprain participated. An isokinetic dynamometer was used to compare motion perception threshold, passive position sense, and passive ankle stiffness between groups. To evaluate the influence of passive stiffness on proprioceptive acuity, individuals in the lateral functional ankle instability group were divided into 2 subgroups: "high" and "low" passive ankle stiffness. Results The functional ankle instability group exhibited increased motion perception threshold when compared with the corresponding limb of the control group. Between-group differences were not found for passive position sense and passive ankle stiffness. Those in the functional ankle instability group with higher passive ankle stiffness had smaller motion perception thresholds than those with lower passive ankle stiffness. Conclusion Unlike motion perception threshold, passive position sense is not affected by the presence of functional ankle instability. Passive ankle stiffness appears to influence proprioceptive acuity in persons with functional ankle instability. J Orthop Sports Phys Ther 2017;47(12):899-905.

    Studies have shown participation in sport is lower among girls than boys, decreases as students matriculate through high school, is lowest among Black and Hispanic girls and has a positive relationship with SES. With sport recognized as a contributor to physical activity and health in adolescents, consideration of diminishing rates of participation appears warranted. The purpose of this study was to identify patterns related to differences in self-reported sport participation between genders, ethnic groups, grades and SES. This study was a cross-sectional, secondary analysis of data collected for a sport interest survey. All students in grades 8-11 attending middle and high schools were provided an opportunity to participate in the survey. Data from 49,832 students were analyzed. Among the participants, Black girls participated more and White girls participated less than expected. Black boys participated more while White and Asian boys participated less than expected. Reported sport participation was high compared with national data when analyzed by gender and ethnic group. Sport participation was higher in low SES schools compared with high SES schools. The importance of sport as a source of physical activity in underserved groups is significant.

    The increased prevalence of childhood obesity has also been attributed to low physical activity (PA) levels. Understanding factors affecting child PA levels is especially important considering the benefits PA offers to youth. This study therefore examined different correlates affecting habitual PA and sports participation in primary school children. Height and weight were measured during a school visit in 1714 children (7.1 ± .6 years). PA and behavioural correlates were assessed by parental questionnaire. The effect of various correlates on PA as well as participation in organized sports was assessed using logistic regression analysis. Significant correlates of PA and sports participation were engagement in sporting activities outside of clubs and children's weight status. Playing outdoors for more than 60 min/day was significant for PA, having well educated parents and being male. Participation in sports was influenced by children's media consumption, active travel to school and having active parents. No influence was found for migration, income, parental weight status and health consciousness. In this study, a multiplicity of independent correlates of PA and sports participation, which require a broad approach to promote an active lifestyle, have been considered. Understanding these factors might support the development of effective health-promoting interventions. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available A case – control study of 257 women with breast cancer and 565 control women was conducted to investigate the effect of life-time sport activity on breast cancer risk. Information was collected by questionnaire about sports played, frequency of participation and duration. The activity levels were determined using frequency variable weighted for metabolic equivalents of energy expenditure (MET. Multivariate logistic regression analyses were used to compute odds ratios (ORs and 95% confidence intervals (CIs. A full assessment of confounding and effect modification was undertaken. The odds ratios for increasing tertiles of sport activity were 1.00 (referent, 0.50 (CI: 0.33-0.76 and 0.44 (CI: 0.28-0.64, respectively (P-trend = 0.000. Comparing sport active women to inactive women the OR was 0.49 (CI: 0.35-0.69. Models stratified according to body mass index, age at menarche, age at first full term pregnancy, intake of vegetables and fruits, and experience of stress were examined. In models stratified the risks of breast cancer were also reduced with higher levels of activity in sport. The conclusion is that women who participated in sports have a reduced risk of breast cancer.

The accessibility of sports facilities is reported to have considerable association with the amount of physical activity a person participates in. Therefore, we investigated the association between subjectively assessed accessibility of sports facilities and physical activity among Korean adults. Methods We obtained data from the 2012 Community Health Survey. Physical activity was measured based on weekly metabolic equivalent task (MET hours according to the International Physical Activity Questionnaire (IPAQ. Sociodemographic, economic, and health variables were used as covariates in a logistic regression model. Results A total 201,723 participants were included in this study. Participants with easy access to sports facilities participated in physical activity more often than those without easy access (OR = 1.16, 95 % CI 1.13–1.20. More physical activity was generally observed if participants had a history of depression or if participants were among the white-collar or urban subgroups. Conclusion Our results showed that the accessibility of sports facilities is associated with physical activity. Therefore, it is crucial to consider the accessibility of sports facilities when promoting an environment conducive to physical activity or designing programs for enhancing physical activity.

    Full Text Available Abstract Background Since knee complaints are common among athletes and are frequently presented in general practice, it is of interest to investigate the type of knee complaints represented in general practice of athletes in comparison with those of non-athletes. Therefore, the aim of this study is to investigate the differences in type of knee complaints between sport participants, in this study defined as athletes, and non-sport participants, defined as non-athletes, presenting in general practice. Further, differences in the initial policy of the GP, medical consumption, and outcome at one-year follow-up were also investigated. Methods Patients consulting their GP for a new episode of knee complaints were invited to participate in this prospective cohort study. From the total HONEUR knee cohort population (n = 1068 we extracted patients who were athletes (n = 421 or non-athletes (n = 388. Results The results showed that acute distortions of the knee were significantly more diagnosed in athletes than in non-athletes (p = 0.04. Further, more athletes were advised by their GP to 'go easy on the knee' than the non-athletes (p Conclusion There are no major differences in the diagnosis and prognosis of knee complaints between athletes and non-athletes presented to the GP. This implies that there are no indications for different treatment strategies applied in both groups. However, athletes are more often advised to 'go easy on the knee' and to rest than non-athletes. Further, there is a trend towards increased medical consumption among athletes while functional disability and pain are lower than among the non-athletes.

    A danger for patients with idiopathic scoliosis results not only from push but also from bendstress. For this reason patients treated with a brace should wear it in sports except swimming. Sports with permanent unilateral torsion are to be avoided. Sports with an extremely lordotic or kyphotic effect may be positive in patients with severe kyphosis or lordosis. The patients should take part in school sport activities.

    The relationship between sport participation and BMI in children and adolescents is unclear, with some studies showing no association at all and others suggesting that sport is linked to lower BMI. Another possibility, however, is that this relationship is bidirectional, with sport leading to lower BMI but BMI also influencing sport participation. Here, we examine the direction of this association by analyzing a longitudinal dataset. Data come from the Physical Health Activity Study Team (...

    To explore the perceptions of health and physical activity, and the associations between these two areas from a theoretical lifestyle perspective. Data was collected by means of a self-administered questionnaire, among 3019 adults attending centres for preventive medicine in France. Correspondence analysis examined the significance of the relationships between perceptions of health and perceptions of sports and physical activity. Four principal types of subjects emerged from the factor analyses expressing four different lifestyle patterns. "Non physically active lifestyle: a feeling of not being healthy", "Physically active lifestyle, pleasure/leisure-oriented", "Necessarily physically active lifestyle, regardless of health", "Physically active lifestyle aimed at stress relief". The sociological approach helps tackle sports and physical activity as behaviour patterns but also and especially as a health orientation connected with the socio-economical climate. This approach also gives sports practice back its meaningful cultural dimension.

    Full Text Available Background: Football is the world's most popular sport. There are over 240 million registered players worldwide and many more recreational footballers. The knee is a complex joint with many components making it vulnerable to a variety of injuries. The study has investigated the effect of knee proprioception error on injured and uninjured male professional footballers. Methods: This was a cross sectional comparative study with hundred and six (106 male professional footballers were selected for the study as per the selection criteria. Hundred and eighteen injured and ninety four uninjured knee samples were analysed for this study. Photographic analysis method was used to evaluate proprioception error at inner, middle and outer range of knee joint. Proprioception error of knee joint was measured at inner range, middle range and outer range for injured and uninjured groups. Data analysis found that there is significant difference in proprioception error between the groups. Result: Comparative study was performed using independent t’ test for proprioception error between knee injured and uninjured groups. P<0.05 were considered as significant difference in effect for this study. The means of knee injured and uninjured groups were 6.08 and 5.55 respectively with t’ value 2.21 and degree of freedom 634. The study found that proprioception error has significant difference in effect on knee injury, with P< 0.03*. Conclusion: The study concluded that proprioception error was varied between knee injured and uninjured groups. Proprioception error of knee joint was more among injured male professional footballers compared to the uninjured footballers.

    Full Text Available This paper examines the responses of state and third sector agencies to the emergence of child abuse in sport since the mid-1980s. As with other social institutions such as the church, health and education, sport has both initiated its own child protection interventions and also responded to wider social and political influences. Sport has exemplified many of the changes identified in the brief for this special issue, such as the widening of definitional focus, increasing geographic scope and broadening of concerns to encompass health and welfare. The child protection agenda in sport was initially driven by sexual abuse scandals and has since embraced a range of additional harms to children, such as physical and psychological abuse, neglect and damaging hazing (initiation rituals. Whereas in the 1990s, only a few sport organisations acknowledged or addressed child abuse and protection (notably, UK, Canada and Australia, there has since been rapid growth in interest in the issue internationally, with many agencies now taking an active role in prevention work. These agencies adopt different foci related to their overall mission and may be characterised broadly as sport-specific (focussing on abuse prevention in sport, children’s rights organisations (focussing on child protection around sport events and humanitarian organisations (focussing on child development and protection through sport. This article examines how these differences in organisational focus lead to very different child protection approaches and “solutions”. It critiques the scientific approaches used thus far to inform activism and policy changes and ends by considering future challenges for athlete safeguarding and welfare.

    The aim of the study was to investigate the effects of sport activity on health-related quality of life (HRQoL) of solid organ transplant recipients participating in sports competitions. A group of 168 sportive transplanted patients (STP), a group of 97 nonsportive transplanted patients (NSTP), and a group of 152 sportive healthy controls (SHC) were compared on the eight scales of the SF-36 questionnaire. STP and NSTP reported significantly lower scores than SHC on the physical functioning scale. STP did not differ from SHC in the Role-Physical, General Health, and Vitality scales, while NSTP reported significantly lower scores. STP obtained higher scores than NSTP and SHC on Mental Health. Among STP, the effect of quantity of sport activity was significant on General Health and Role Emotional, with more sport activity associated with higher HRQoL. Organ failure and post-transplant therapies may have negative consequences on HRQoL. Sports activities and participation in sports competitions can reduce this impact, improving general and psychological functioning of solid organ transplant recipients.

Material & Methods: the special surveys of students and teachers of KhSAPC, and also students, who train in sports club "Politekhnik", and the students who are engaged in sports sections NLA were conducted for the solution of purposes. Results: the most important qualities of the personality which sports activities influence are: formation of "confidence", "emotional stability", and "orientation to achievement" at sportsmen. According to most of the interviewed sportsmen and experts, the authority of the coach is not significant factor which influences the identity of sportsmen. Conclusions: it is established as a result of the conducted researches that sports activities most of all influence the formation of confidence, emotional stability and orientation to achievement at sportsmen. Results of the research demonstrate also that the identity of the sportsman is most influenced by the competitive relationship which develops in the course of competitive activity. Results of the research also indicate disturbing tendency which is shown that most of sportsmen connect the end of their sports career with injuries.

    We examined the long-term effects of youth leisure time physical activity (LTPA) and sports participation on the prevalence of chronic work stress in adulthood. Participants (326 men and 338 women) aged 9 to 18 years were initially enrolled in 1980 and followed until 2007. Data were collected using questionnaires and bicycle ergometry in a subgroup. High youth LTPA and sports participation predicted lower chronic job strain in both sexes. The association was mediated by type A leadership. Participation and persistence in organized youth sports followed a similar pattern. In the subgroup, adult physical fitness only partly accounted for the association. Sustained involvement in youth physical activity and sport lasting at least 3 years is associated with reduced chronic job strain in adulthood. The association was partially explained by type A leadership and physical fitness.

    Because sustained physical activity is important for a healthy life, this paper examined whether a greater diversity of sport activities during adolescence predicts higher levels of leisure-time physical activity (LTPA) in adulthood. From sport activity participation reported by 17-year-old twins, we formed five groups: 1, 2, 3, 4, and 5+ different sport activities. At follow-up in their mid-thirties, twins were divided into four activity classes based on LTPA, including active commuting. Multinomial regression analyses, adjusted for several confounders, were conducted separately for male (N=1288) and female (N=1770) participants. Further, conditional logistic regression analysis included 23 twin pairs discordant for both diversity of sport activities in adolescence and LTPA in adulthood. The diversity of leisure-time sport activities in adolescence had a significant positive association with adulthood LTPA among females. Membership in the most active adult quartile, compared to the least active quartile, was predicted by participation in 2, 3, 4, and 5+ sport activities in adolescence with odds ratios: 1.52 (P=.11), 1.86 (P=.02), 1.29 (P=.39), and 3.12 (P=5.4e-05), respectively. Within-pair analyses, limited by the small sample of twins discordant for both adolescent activities and adult outcomes, did not replicate the association. A greater diversity of leisure-time sport activities in adolescence predicts higher levels of LTPA in adulthood in females, but the causal nature of this association remains unresolved. © 2017 John Wiley & Sons A/S.

  9. Associations between proprioceptive neural pathway structural connectivity and balance in people with multiple sclerosis

    Full Text Available Mobility and balance impairments are a hallmark of multiple sclerosis (MS, affecting nearly half of patients at presentation and resulting in decreased activity and participation, falls, injuries, and reduced quality of life. A growing body of work suggests that balance impairments in people with mild MS are primarily the result of deficits in proprioception, the ability to determine body position in space in the absence of vision. A better understanding of the pathophysiology of balance disturbances in MS is needed to develop evidence-based rehabilitation approaches. The purpose of the current study was to 1 map the cortical proprioceptive pathway in-vivo using diffusion weighted imaging and 2 assess associations between proprioceptive pathway white matter microstructural integrity and performance on clinical and behavioral balance tasks. We hypothesized that people with MS (PwMS would have reduced integrity of cerebral proprioceptive pathways, and that reduced white matter microstructure within these tracts would be strongly related to proprioceptive-based balance deficits. We found poorer balance control on proprioceptive-based tasks and reduced white matter microstructural integrity of the cortical proprioceptive tracts in PwMS compared with age-matched healthy controls. Microstructural integrity of this pathway in the right hemisphere was also strongly associated with proprioceptive-based balance control in PwMS and controls. Conversely, while white matter integrity of the right hemisphere’s proprioceptive pathway was significantly correlated with overall balance performance in healthy controls, there was no such relationship in PwMS. These results augment existing literature suggesting that balance control in PwMS may become more dependent upon 1 cerebellar-regulated proprioceptive control, 2 the vestibular system, and/or 3 the visual system.

    To compare the associations between weight status and different forms of physical activity among adolescents. We conducted telephone surveys with 1718 New Hampshire and Vermont high school students and their parents as part of a longitudinal study of adolescent health. We surveyed adolescents about their team sports participation, other extracurricular physical activity, active commuting, physical education, recreational activity for fun, screen time, diet quality, and demographics. Overweight/obesity (BMI for age ≥ 85th percentile) and obesity (BMI for age ≥ 95 percentile) were based on self-reported height and weight. Overall, 29.0% (n = 498) of the sample was overweight/obese and 13.0% (n = 223) were obese. After adjustments, sports team participation was inversely related to overweight/obesity (relative risk [RR] = 0.73 [95% confidence interval (CI): 0.61, 0.87] for >2 sports teams versus 0) and obesity (RR = 0.61 [95% CI: 0.45, 0.81] for >2 sports teams versus 0). Additionally, active commuting to school was inversely related to obesity (RR = 0.67 [95% CI: 0.45, 0.99] for >3.5 days per week versus 0). Attributable risk estimates suggest obesity prevalence would decrease by 26.1% (95% CI: 9.4%, 42.8%) if all adolescents played on 2 sports teams per year and by 22.1% (95% CI: 0.1%, 43.3%) if all adolescents walked/biked to school at least 4 days per week. Team sport participation had the strongest and most consistent inverse association with weight status. Active commuting to school may reduce the risk of obesity, but not necessarily overweight, and should be studied further. Obesity prevention programs should consider strategies to increase team sport participation among all students.

    Television (TV) viewing has been associated with obesity although the effects of specific TV content on health and other behaviours remains unknown. We examined the association between watching sport on TV, physical activity levels, and risk of obesity. We studied 6,733 (aged 64.9 ± 9.2 yrs) men and women from the English Longitudinal Study of Ageing, a prospective study of community dwelling older adults. Data were collected on self reported TV time and content, and physical activity. Nurses measured height and weight for the calculation of body mass index. On average, participants reported viewing TV for 5.3 ± 4.1 hours per day and 30.3% of the sample watched sport on TV at least twice a week. There was no association between watching sport and physical activity levels. Participants that watched sports every day were at higher risk of obesity [odds ratio = 1.39, 95% CI, 1.15, 1.68) after adjustment for age, sex, smoking, alcohol, physical activity, total TV time, disability, and self-rated health. Watching elite athletes may have no role in the promotion of physical activity in older adults, which has implications for staging large sporting events with physical activity legacy promises.

    Physical activity has been associated with widespread anatomical and functional brain changes that occur following acute exercise or, in the case of athletes, throughout life. High levels of physical activity through the practice of sports also lead to better general health and increased cognitive function. Athletes are at risk, however, of suffering a concussion, the effects of which have been extensively described for brain function and anatomy. The level to which these effects are modulated by increased levels of fitness is not known. Here, we review literature describing the effects of physical activity and sports concussions on white matter, grey matter, neurochemistry and cortical excitability. We suggest that the effects of sports concussion can be coufounded by the effects of exercise. Indeed, available data show that the brain of athletes is different from that of healthy individuals with a non-active lifestyle. As a result, sports concussions take place in a context where structural/functional plasticity has occurred prior to the concussive event. The sports concussion literature does not permit, at present, to separate the effects of intense and repeated physical activity, and the abrupt removal from such activities, from those of concussion on brain structure and function.

    2014-01-01

    Background Television (TV) viewing has been associated with obesity although the effects of specific TV content on health and other behaviours remains unknown. We examined the association between watching sport on TV, physical activity levels, and risk of obesity. Methods We studied 6,733 (aged 64.9 ± 9.2 yrs) men and women from the English Longitudinal Study of Ageing, a prospective study of community dwelling older adults. Data were collected on self reported TV time and content, and physical activity. Nurses measured height and weight for the calculation of body mass index. Results On average, participants reported viewing TV for 5.3 ± 4.1 hours per day and 30.3% of the sample watched sport on TV at least twice a week. There was no association between watching sport and physical activity levels. Participants that watched sports every day were at higher risk of obesity [odds ratio = 1.39, 95% CI, 1.15, 1.68) after adjustment for age, sex, smoking, alcohol, physical activity, total TV time, disability, and self-rated health. Conclusions Watching elite athletes may have no role in the promotion of physical activity in older adults, which has implications for staging large sporting events with physical activity legacy promises.

For an informed diagnosis, prognosis, and treatment planning, it is essential to be able to distinguish between healthy performance and deficits following the neurological injury. Since there is some evidence that proprioception declines with age and stroke occurs predominantly in the elderly population, it is important to create a healthy reference model in this specific age group. However, most studies investigate age effects by comparing young and elderly subjects and do not provide a model within a target age range. Moreover, despite the functional relevance of the hand in activities of daily living, age-based models of distal proprioception are scarce. Here, we present a proprioception model based on the assessment of the metacarpophalangeal joint angle difference threshold in 30 healthy elderly subjects, aged 55–80 years (median: 63, interquartile range: 58–66, using a robotic tool to apply passive flexion–extension movements to the index finger. A two-alternative forced-choice paradigm combined with an adaptive algorithm to define stimulus magnitude was used. The mixed-effects model analysis revealed that aging has a significant, increasing effect on the difference threshold at the metacarpophalangeal joint, whereas other predictors (eg, tested hand or sex did not show a significant effect. The adaptive algorithm allowed reaching an average assessment duration <15 minutes, making its clinical applicability realistic. This study provides further evidence for an age-related decline in proprioception at the level of the hand

    To examine cross-sectional and longitudinal associations between socioeconomic status (SES), gender, sports participation and moderate-to-vigorous physical activity (MVPA) in adolescents. Project EAT (Eating Among Teens), a population-based longitudinal study followed a socioeconomically and ethnically diverse sample of 1709 adolescents in 1998-1999 (Time 1) and 2003-2004 (Time 2). Mixed model regression analyses were used to examine longitudinal trends in MVPA as a function of SES and previous sports involvement. For both genders, participation in organized sports and weekly hours of MVPA were positively associated with SES. On average, MVPA decreased between high school and young adulthood for both genders. Adolescents who participated in sports during high school showed a steeper decline in weekly hours of MVPA than their non-sports-participating counterparts. SES had a significant moderating effect on the change in MVPA over time for boys who participated in organized sports, with low SES boys showing a steeper decline in MVPA between time periods than higher SES boys. Although on average, a statistically significant difference in MVPA between previous sports participants and nonparticipants remained at Time 2, for all SES groups and both genders, the gap between hours of MVPA was either overcome or significantly narrowed by young adulthood. Increased dependence on organized sports for MVPA may be insufficient to meet the needs of youth following high school, especially for low SES youth. Designing physical activity promotions that reach and address the unique needs of lower SES youth and families is a public health priority.

    The purpose of this study was to investigate whether Danish children from immigrant backgrounds are less physically active than children from the ethnic majority, and to investigate the possible reasons for any differences found. Accelerometer measures of physical activity as well as questionnaire data about organised sports, family demography, resources and values were collected from 594 children of whom 67 had other ethnic background than Danish. Data were collected when the children were 6-7 years old and again later when the children were 9-10 years old. It was found that children from immigrant backgrounds were not less physically active than other children when their amounts of daily physical activity were measured by direct objective measures, despite their participation rate in organised sports being much lower. Using multiple logistic regression modelling, this study showed that lack of parental experience with organised sports and lack of economic/material resources explained much of the difference in sports participation. Children of immigrant background had significant lower participation in club sports but this did not affect their overall physical activity level.

    This study reports the positive physical, emotional and psychosocial changes induced by sport activity in a Paralympic swimmer with Charcot-Marie-Tooth (CMT) type 4A. When we compared evaluations before initiating sport activity with those after five years of competitive activity, we found: i) increased proximal muscles strength of upper limbs; ii) augmented ability to propel wheelchair independently; iii) improved quality of life; iv) reduced trait anxiety and striking improvement of depression; v) enhanced self-esteem. Longitudinal studies in large cohorts to evaluate the positive effects of sport activity are needed to support provision of evidence-based advice to patients and families.

    We investigated knee functions and a return to sports in 50 competitive athlete patients treated with arthroscopic anterior cruciate ligament reconstruction using double-looped STG augmented by woven polyester at a 1-year follow-up. There were 25 males and 25 females with a mean age of 24.3 years (range: 19-39 years). The majority of preinjury sports were basketball, volleyball and soccer. Athletic rehabilitation including agility training and sports-specific training was started at 12 weeks. Fourty patients (80%) was rated as normal or nearly normal on the assessment of International Knee Documentation Commitee postoperatively. Fourty-eight patients (96%) obtained full range of motion, and the mean quadriceps muscle strength of the injured side was 91.3%of that of the uninjured side. As for a return to sports, 46 patients (92%) were able to do fully competitive sports at a mean of 8.1 postoperative months. These results suggest that arthroscopic reconstruction using augmented double-looped STG allows early athletic rehabilitation, and lead satisfactory outcome as well as a reliable and early return to preinjury level of sport activity for the majority of the competitive athlete patients.

    1. To determine whether individuals with chronic ankle instability (CAI) have lower proprioception sensitivity scores from a test on the Active Movement Extent Discrimination Apparatus (AMEDA). 2. To determine whether individuals with CAI can improve proprioception sensitivity scores with repeated active movement testing using the AMEDA. 3. To assess the test-retest reliability of the AMEDA. A cohort study comparing those with CAI or healthy ankles. University clinical laboratory. 61 healthy university students, 36 with CAI, 25 with stable ankles. A 2-way ANOVA was conducted to compare performance of CAI and stable ankle groups, over 3 test repetitions on the AMEDA. The reliability intra-class correlation coefficient (ICC) was obtained for test repetitions. The scores improved in both groups when the AMEDA test was repeated (p = proprioception test scores differed, with the CAI group showing a slower learning rate than the stable ankle group (p = 0.047). The ICC for the whole group across the three trials was 0.80 (95% CI = 0.69 to 0.87, p = proprioception scores more slowly upon repeated AMEDA testing, suggesting differences in learning strategies.

    2016-04-01

    Exercise is an important therapeutic tool in the management of diabetes in older people. Aim of this study was to assess the relationship among type II diabetes, sport, overweight, and symptomatic Achilles tendinopathy in elderly subjects. Thirty-eight patients suffering from Achilles tendinopathy and thirty-eight controls were enrolled. The prevalence of diabetes and sport practice as well as BMI and Glycated Hemoglobin (HbA1c) values were registered. An ultrasound evaluation of Achilles tendon was performed. Patients showed an increased prevalence of diabetes (42 vs. 13.1 %, p = 0.004), and practice of sport (60.5 vs. 28.9 %, p = 0.0001), and higher BMI values (26.8 ± 3 vs. 24.8 ± 2.3, p = 0.001). Sonographic abnormalities, being diagnostic criteria, were present in all the patients with Achilles tendinopathy, but signs of degeneration were also found in 36.8 % of asymptomatic controls. Symptomatic subjects with diabetes, compared to those without, showed a higher prevalence of severe degeneration (75 vs. 36.3 %, p = 0.01). HbA1c values were significantly lower in sport practitioners, both diabetics and non-diabetics. Moreover, patients practicing sport showed a trend towards lower BMI values, compared to the sedentary counterpart. Sport practice in elderly diabetics provides relevant metabolic advantages, reducing HbA1c and BMI. However, some sport activities (e.g., speed walking, jogging or tennis) can expose to the risk of Achilles tendinopathy. So, sport practice should be encouraged, but practitioners should follow individual training programs and be submitted to periodic sonographic controls.

  2. Organized Sports and Unstructured Active Play as Physical Activity Sources in Children From Low-Income, Chicago Households.

    2016-08-01

    This study tested associations of organized sports participation and unstructured active play with overall moderate and vigorous physical activity (MVPA) in low-income children and examined factors associated with participation frequency. Research staff visited 88 low-income Chicago households with children ages 6-13 years. MVPA was assessed through 7-day accelerometry. Researchers documented the home availability of physical activity equipment. Caregivers reported on child participation in organized sports and unstructured active play, family support for physical activity, perceived neighborhood safety, and access to neighborhood physical activity venues. Despite similar participation in organized sports and unstructured active play, boys accumulated more MVPA than girls. MVPA was predicted by an interaction between gender and unstructured active play. Boys accumulated 23-45 additional minutes of weekday MVPA and 53-62 additional minutes of weekend MVPA through unstructured active play, with no such associations in girls. Higher reported neighborhood safety and family support for physical activity were associated with engagement in unstructured active play for both genders, and with participation in organized sports for girls. Physical activity interventions for low-income, urban children should emphasize unstructured active play, particularly in boys. Fostering family support for physical activity and safe play environments may be critical intervention components.

    Abstract Physical activity has multiple health benefits but may also increase the risk of developing musculoskeletal pain (MSP). However, the relationship between physical activity and MSP has not been well characterized. This study examined the dose–response relationship between sports activity and MSP among adolescents. Two school-based serial surveys were conducted 1 year apart in adolescents aged 12 to 18 years in Unnan, Japan. Self-administered questionnaires were completed by 2403 students. Associations between time spent in organized sports activity and MSP were analyzed cross-sectionally (n = 2403) and longitudinally (n = 374, students free of pain and in seventh or 10th grade at baseline) with repeated-measures Poisson regression and restricted cubic splines, with adjustment for potential confounders. The prevalence of overall pain, defined as having pain recently at least several times a week in at least one part of the body, was 27.4%. In the cross-sectional analysis, sports activity was significantly associated with pain prevalence. Each additional 1 h/wk of sports activity was associated with a 3% higher probability of having pain (prevalence ratio = 1.03, 95% confidence interval = 1.02-1.04). Similar trends were found across causes (traumatic and nontraumatic pain) and anatomic locations (upper limbs, lower back, and lower limbs). In longitudinal analysis, the risk ratio for developing pain at 1-year follow-up per 1 h/wk increase in baseline sports activity was 1.03 (95% confidence interval = 1.02-1.05). Spline models indicated a linear association (P sports, the more likely they were to have and develop pain. PMID:26894915

    To determine whether adolescent attitudes towards sports, exercise, and fitness predict moderate-to-vigorous physical activity 5 and 10 years later. A diverse group of 1902 adolescents participating in Project Eating and Activity in Teens, reported weekly moderate-to-vigorous physical activity and attitudes toward sports, exercise, and fitness in Eating and Activity in Teens-I (1998-99), Eating and Activity in Teens-II (2003-04), and Eating and Activity in Teens-III (2008-09). Mean moderate-to-vigorous physical activity was 6.4, 5.1, and 4.0 hours/week at baseline, 5-year, and 10-year follow-up, respectively. Attitudes toward sports, exercise, and fitness together predicted moderate-to-vigorous physical activity at 5 and 10 years. Among the predictors of 5- and 10-year moderate-to-vigorous physical activity, attitude's effect size, though modest, was comparable to the effect sizes for sports participation and body mass index. Adolescents with more-favorable attitudes toward sports, exercise, and fitness engaged in approximately 30%-40% more weekly moderate-to-vigorous physical activity at follow-up (2.1 hour/week at 5 years and 1.2 hour/week at 10 years) than those with less-favorable attitudes. Adolescents' exercise-related attitudes predict subsequent moderate-to-vigorous physical activity independent of baseline behavior suggesting that youth moderate-to-vigorous physical activity promotion efforts may provide long-term benefits by helping youth develop favorable exercise attitudes.

    The purpose of this study was to provide comprehensive long-term data about sports activity levels in patients following total knee arthroplasty (TKA) and to determine the impact of pre-operative function, pain and specific performed sports on the results. 236 patients who have undergone TKA for severe osteoarthritis of the knee were asked to provide specific information regarding exercised types of sports before surgery and after at least 10 years following TKA. Pre- and postoperative function and pain were evaluated by the use of Tegner-, WOMAC- and VAS Score. After a mean of 14.9 years, a significant improvement regarding pain and function was observed. Pre-operative Tegner- and WOMAC scores revealed significant positive correlations with the post-operative Tegner-Score. Accordingly, a high percentage of patients (70.9%) stayed actively involved in sports. Nevertheless, the number of performing patients has decreased according to the sports impact. 71.3% continued practising low-impact-, 43.7% intermediate-impact sports whereas only 16.4% kept performing high impact sports. We conclude that TKA is highly effective in long-time pain reduction as well as improvement of function. Additionally, we found considerable sports activities preserved in the investigated series. However, sports activities in particular, seem to decrease according to the impact of sports.

    In outdoor activities, it seems reasonable that the longer children spend in spontaneous physical activity (PA), the higher the probability of being active. Indeed, the time spent outdoor has been identified as a variable consistently associated with the children's PA. Outdoor playing, such as the organized sports practice, appears associated with healthier lifestyle standards. All the recommendations mention the importance of increasing daily PA practice in children and teenagers, but few studies highlight the relationship between outdoor play and the recommended PA levels. The purpose of this study is to investigate the relationships between the frequency of outdoor play, the frequency of the organized sports practice, and the compliance of the recommendations for PA practice in children in the inner city area of Porto. The sample of this study is composed of 422 individuals (mean age of 11.6 years). Two hundred and twenty-five of them were girls and 197 were boys from the sixth grade (elementary schools located in the inner city area of Porto). PA was objectively evaluated using accelerometers. Participants reported frequency of participation in different PA contexts, such as sports practice and outdoor play. The results show a predictor effect of participating in sports three or more times per week on compliance of PA guidelines. In conclusion, organized sports practice seems more effective than outdoor play to reach the recommended levels of PA in children.

    Adult physical activity scales are used with children but may not be valid in this population. This study assesses the appropriateness and comprehensibility of currently used physical activity scales in children, identifies sources of response errors, and suggests scale modifications. Cognitive interviews were conducted with 30 children who had a lower extremity injury, purposefully sampled based on age and sex. Interviews were conducted to identify children's comprehension of 6 physical activity questionnaires: Tegner activity scale, Cincinnati Knee Rating System, KOOS-Child, Marx activity scale, HSS Pedi-FABS, and KOS sports activity scale. The Tegner scale uses complex activity level descriptions (eg, competitive vs. recreational sports, types of sports and inclusion of work-related physical activity). Activity frequency, description of movement, and sport type in the Cincinnati Knee Rating System led to response mapping issues in many children. Most children felt the KOOS-Child pictures depicting activities were helpful, but not all found the 7-day timeframe relevant. Whereas, most children found the Marx scale and HSS Pedi-FABS items clear, concise, and easy to answer. Children reported difficulties differentiating between endurance and duration items used in the HSS Pedi-FABS. The consistent response format of the KOS sports activity scale was considered a positive attribute although children had trouble comprehending terms such as grating and grinding. Children found some scales too difficult to answer, whereas others required modifications, particularly in general instruction, language, question format, and mapping (matching an answer to potential options) to adapt to the specific needs of children.

    Recently, proprioception deficits of the rotator cuff and the deltoid muscles have been suggested to play a pivotal role in the subacromial impingement syndrome (SIS). To date, there are no study has been found where the kinesthesia and joint position senses have been evaluated together in SIS. To investigate the shoulder proprioception in patients with SIS. Sixty-one patients with SIS and 30 healthy controls, aging between 25 and 65 years, were included in the study. Main outcome measure was proprioception, assessed with an isokinetic dynamometer. Kinesthesia, active and passive joint repositioning senses were tested at 0° and 10° external rotation. All tests were repeated 4 times and the mean of angular errors were obtained. The mean age was 49.14 ± 10.27 and 48.80 ± 11.09 years in patient group and in control group respectively. No significant difference was found between two groups in terms of age, gender and dominance. When involved and uninvolved shoulders of the patient group were compared, kinesthesia, active and passive joint position senses were significantly impaired in involved shoulders at all angles (P shoulders of the patient group were compared to the control group, kinesthesia, active and passive joint position senses were significantly impaired in involved shoulders in patient group at all angles (P shoulders of the patient group were compared to the control group, kinesthesia at 10° was significantly impaired (P shoulder proprioception was impaired in patients with SIS. This proprioceptive impairment was found not only in involved shoulders but also in uninvolved shoulders in patients with SIS.

    [Purpose] To investigate possible cross effects of proprioception training on proprioception repositioning accuracy of the knee joint and on balance in healthy subjects. [Subjects and Methods] Sixty healthy college students and faculty members from faculty of physical therapy, Cairo University were recruited to participate. Participants were randomly assigned to training group (n=30) and control group (n=30). The training group received proprioceptive training program only for the dominant leg while the control group did not receive any kind of training. Outcome measures were twofold: (1) proprioception repositioning accuracy quantified through the active repositioning test for the non-dominant knee; and (2) balance stability indices determined through using Biodex balance system. Measurements were recorded before and after 8 weeks of proprioception training. [Results] There were significant decrease in the error of repositioning accuracy and the stability indices including anterposterior stability index, mediolateral stability index, and overall stability index of training group, measured post training, compared with control group. [Conclusion] Proprioception training has significant cross training effects on proprioception repositioning accuracy of the knee joint and on balance among healthy subjects.

    Full Text Available ABSTRACTInjuries to the knee, including intra-articular fractures, ligamentous ruptures, and meniscal and articular cartilage lesions, are commonplace within sports. Despite advancements in surgical techniques and enhanced rehabilitation, athletes returning to cutting, pivoting, and jumping sports after a knee injury are at greater risk of sustaining a second injury. The clinical utility of objective criteria presents a decision-making challenge to ensure athletes are fully rehabilitated and safe to return to sport. A system centered on specific indicators that can be used to develop a comprehensive profile to monitor rehabilitation progression and to establish return to activity criteria is recommended to clear athletes to begin a progressive and systematic approach to activities and sports. Integration of a sports knee injury performance profile with return to activity criteria can guide clinicians in facilitating an athlete's safe return to sport, prevention of subsequent injury, and life-long knee joint health.

    Full Text Available Purpose. To evaluate the lower limb proprioceptive sensation in patients with femoral amputation who received an artificial joint. Materials and Methods. 22 patients (18 men, 4 women, 24–65 years old (mean: 42, who had undergone above-the-knee joint amputation and underwent evaluation of proprioception using joint reposition in a predetermined angle of 15° knee flexion. The measurements were applied using a conventional goniometer to both amputated and healthy knees. The last ones were used as internal control. All patients performed an active knee flexion from hyperextension to 15° in a closed kinetic chain in order to evaluate proprioceptive sensation of the knee joint using the joint position sense (JPS method during specific controllable circumstances very close to normal gait. Results. JPS at 15° flexion for the amputated knee was calculated to be equal to 13.91 (SD = ±4.74, and for the healthy side it was equal to 14.15 (SD = ±2.61. No statistically significant differences were detected between the amputated and the healthy limb (. Conclusions. The proprioceptive information of the stumps did not appear to be affected significantly after thigh amputation and application of artificial prosthesis when JPS at 15° was evaluated. It seems that these patients compensate the loss of the knee sensory receptors via alternative mechanisms.

    Anterior cruciate ligament (ACL) tears are common injuries in adolescent athletes, especially in those who bear high stress on their knees due to shearing forces. The goal of the surgical procedures in skeletally immature patients is to restore joint stability avoiding the adverse effects on the growth process. The aim of this study was to verify the return of the skeletally immature professional athletes to sports in the long-term, following ACL reconstruction with the original all-inside technique and with manual drilling. This study included 24 athletes (14 boys, 10 girls; mean age: 13.15 years, range: 9-14 years) who had radiographic evidence of open physes, were less than 14 years of age at the time of surgery and those with a minimum follow-up of eight years. All patients completed a questionnaire, the IKDC subjective knee evaluation form, and Tegner Activity Scale. Biomechanical outcomes of the KT-1000 arthrometer, gait analysis, and stabilometric and isokinetic results were also evaluated. A plain radiograph of both lower limbs was taken to obtain a precise measurement of the limb length and mechanical axis angles. The patients returned to sport activities in a mean time of 6.43 months. No rerupture or resurgery due to growth abnormalities was observed. The mean difference in length between the operated and contralateral legs was 0.4 (range: -0.2 to 0.7) cm. The mean side-to-side difference measured with the KT-1000 arthrometer was 5.2 (range: 3.5 to 7) mm in the preoperative and 0.8 (range: 0 to 2.5) mm in the postoperative measurements. In conclusion, the original all-inside technique with manual drilling with a half tunnel and short graft seems to be a very effective technique for the surgical management of ACL injuries in pediatric/adolescent athletes. A good rate of return to sports at pre-injury levels or higher, high patient satisfaction and a decent motor and proprioceptive function is possible as shown by our analysis.

    The last few decades have seen substantial growth in the populations of competitive athletes and highly active people (CAHAP). Although vigorous physical exercise is an effective way to reduce the risk of cardiovascular (CV) disease, CAHAP remain susceptible to inherited and acquired CV disease, and may be most at risk for adverse CV outcomes during intense physical activity. Traditionally, multidisciplinary teams comprising athletic trainers, physical therapists, primary care sports medicine physicians, and orthopedic surgeons have provided clinical care for CAHAP. However, there is increasing recognition that a care team including qualified CV specialists optimizes care delivery for CAHAP. In recognition of the increasing demand for CV specialists competent in the care of CAHAP, the American College of Cardiology has recently established a Sports and Exercise Council. An important primary objective of this council is to define the essential skills necessary to practice effective sports cardiology. Copyright © 2017. Published by Elsevier Inc.

    Science.gov (United States)

    2014-05-01

    The practice of combat sports creates a potential for training- and sports-related injuries among military members. During the 4-year surveillance period, there were 12,108 cases of injuries associated with combat sports among active component service members; the overall incidence rate was 21.0 per 10,000 person-years (p-yrs). The rates were higher among service members who were male, Hispanic, in the youngest age groups, in the Army, junior enlisted, and in combat-specific occupations. The rate among recruit/ trainees (779.4 per 10,000 p-yrs) was more than 165 times the rate among all other active component service members (non-recruits) (4.7 per 10,000 p-yrs). Sprains, strains, and contusions accounted for more than one-half of the primary (first-listed) diagnoses associated with combat sports cases. More serious conditions such as concussions/head injuries and skull/face fractures/intracranial injuries were reported among 3.9% and 2.1% of all cases and were more common among boxing-related cases. Hand/wrist fractures were also common among boxing cases. Wrestling had comparatively greater proportions of dislocations and open wounds. Although the combat sport training provides many physical and mental benefits to the individual, safety practices should be enforced to reduce the most frequent and serious injuries.

    Moderate to Vigorous Physical Activity (MVPA), including sport participation, is an important component of a healthy lifestyle. Scholars have devoted considerable attention to understanding the impact of parenthood on MVPA, albeit only for women. As the impact of fatherhood on men's lives is drawing more and more scholarly and societal attention, the aim of the current article is to provide an systematic overview of studies examining the impact of fatherhood on MVPA. A systematic review was conducted in Google Scholar, Web of Science and Web of Knowledge, using (combinations of) the search terms: father(hood), parent(hood), exercise, physical activity, sport and leisure time. This resulted in 54 papers reporting differences in MVPA and/or sport between fathers and childless men or within men that became father, of which 13 were included. Our overview of findings suggested that fathers spent less time on MVPA compared with childless men, but that fathers did not differ from their childless counterparts on the subarea of sport participation. Differences in time spent on MVPA were strongest between childless men and fathers with young children (< 6 yrs). Our systematic review revealed that fathers spent less time on MVPA compared to childless men, especially when they had young children. Interestingly, linkages between parental status and the subarea of sport participation were not found, which suggests that fathers cut back on other areas of MVPA. Given the impact of MVPA on a healthy lifestyle, future research in this field is warranted.

In the quantitative technique. the final sample comprised 1978 subjects, 51.7% girls and 48.3% boys. Descriptive analysis, inferential analysis (Cramer’s V, and multinomial regression analysis were performed on the data collected with the questionnaire.In the qualitative technique, four focus groups (n = 41were employed: parents, Physical Education teachers, teachers from other areas, and adolsescents. Results show that girls’ dropout rate is three times higher than that of the boys, and they are four times more likely to abandon this lifestyle than boys.The peer group is one of the most powerful informal education agents to influence adolescents’ physical-sport practice, but its influence varies by sex. If friends grant much, some, or very much importance to physical-sport practice, girls are less likely to drop out of such practice, but when boys’ friends grant no importance to physical-sport activity, they are five times more likely to drop out.

    Sports and energy drinks are being increasingly consumed and contain large amounts of sugars, which are known to increase Streptococcus mutans biofilm formation and metabolic activity. The purpose of this in vitro study was to investigate the effects of sports and energy drinks on S. mutans biofilm formation and metabolic activity. S. mutans UA159 was cultured with and without a dilution (1:3 ratio) of a variety of sports and energy drinks in bacterial media for 24 hours. The biofilm was washed, fixed, and stained. Biofilm growth was evaluated by reading absorbance of the crystal violet. Biofilm metabolic activity was measured by the biofilm-reducing XTT to a water-soluble orange compound. Gatorade Protein Recovery Shake and Starbucks Doubleshot Espresso Energy were found to significantly increase biofilm (30-fold and 22-fold, respectively) and metabolic activity (2-fold and 3-fold, respectively). However, most of the remaining drinks significantly inhibited biofilm growth and metabolic activity. Several sports and energy drinks, with sugars or sugar substitutes as their main ingredients inhibited S. mutans biofilm formation. Among the drinks evaluated, Gatorade Protein Recovery Chocolate Shake and Starbucks Doubleshot Energy appear to have cariogenic potential since they increased the biofilm formation and metabolic activity of S. mutans.

    Whereas the links between eye movements and the shifts in visual attention are well established, less is known about how eye position affects the prioritization of visual space. It was recently observed that visual sensitivity varies with the direction of gaze and the level of excitability...... target when the right eye was rotated leftwards as compared with when it was rotated rightwards. This effect was larger after S1(EYE)-rTMS than after rTMS of a control area in the motor cortex. The neural response to retinally identical stimuli in this area could be predicted from the changes in visual...... detectability observed previously, but not from the location of the visual targets relative to the body. These results strongly argue for a modulatory connection from the eye proprioceptive area in the somatosensory cortex to the higher-order visual cortex.

    To determine the frequency of sports physical activity in the urban population of Peru and to identify the sociodemographic, economic, and environmental factors associated with that activity. This study utilized information collected by the country's National Household Survey (Encuesta Nacional de Hogares) in the second quarter of 1997. That Survey is overseen by Peru's National Institute of Statistics and Informatics (Instituto Nacional de Estadística e Informática). The Survey was based on a probabilistic, multistage sample that was stratified for all the urban areas of the country, which was divided into eight geographic regions: metropolitan Lima, northern coast, central coast, southern coast, northern mountains, central mountains, southern mountains, and jungle. In total, 14 913 homes were visited and 45 319 people at least 15 years of age were interviewed. The frequency of engaging in sports physical activity was classified as daily, every other day, weekly, or occasional. "Regular sports activity" (RSA) was defined as engaging in sports either every day or every other day. The preferences for and obstacles to sports practice were also examined. A descriptive analysis of the levels of RSA was carried out for gender, using the chi-square test. The factors associated with RSA were analyzed through conditional multiple logistic regression and analysis of residuals, multicollinearity, and interactions. The level of significance was set at P jungle (15.3%), central mountains (12.8%), and central coast (12.1%). RSA was least common in two regions: southern mountains (9.7%) and metropolitan Lima (10.6%). The income bracket was not associated with RSA. However, other variables associated indirectly with the socioeconomic level - such as having more formal education, being employed, and having access to the Internet or cable television - and consumption of sports information were significantly and directly associated with RSA.

    Abstract Riva, D, Bianchi, R, Rocca, F, and Mamo, C. Proprioceptive training and injury prevention in a professional men's basketball team: A six-year prospective study. J Strength Cond Res 30(2): 461–475, 2016—Single limb stance instability is a risk factor for lower extremity injuries. Therefore, the development of proprioception may play an important role in injury prevention. This investigation considered a professional basketball team for 6 years, integrating systematic proprioceptive activity in the training routine. The purpose was to assess the effectiveness of proprioceptive training programs based on quantifiable instability, to reduce ankle sprains, knee sprains, and low back pain through developing refined and long-lasting proprioceptive control. Fifty-five subjects were studied. In the first biennium (2004–2006), the preventive program consisted of classic proprioceptive exercises. In the second biennium (2006–2008), the proprioceptive training became quantifiable and interactive by means of electronic proprioceptive stations. In the third biennium (2008–2010), the intensity and the training volume increased while the session duration became shorter. Analysis of variance was used to analyze the differences in proprioceptive control between groups, years, and bienniums. Injury rates and rate ratios of injury during practices and games were estimated. The results showed a statistically significant reduction in the occurrence of ankle sprains by 81% from the first to the third biennium (p proprioceptive control improved significantly by 72.2% (p proprioceptive control in single stance may be a key factor for an effective reduction in ankle sprains, knee sprains, and low back pain.

    Ankylosing spondylitis is a chronic inflammatory rheumatic disease that primarily affects the sacroiliac joints and spine, although it may involve entheses, peripheral joints and extraarticular organs. Disease treatment is directed toward the suppression of the inflammatory process and the improvement of the musculoskeletal system function. There are several treatment modalities: education of the patient and members of the family, pharmacological treatment, physical therapy and, in some cases, surgical treatment. An important segment of various modalities of physical therapy belongs to kinesitherapy, sports and recreation whose duration and intensity largely depends not only on the actual functional impairments, but also on the presence of some other disease or contraindications. Kinesitherapy is directed toward maintenance and improvement of the function of the spine, thoracic cavity and large synovial joints as well as the prevention of deformities or contractures. Kinesitherapy and sports programmes may involve individual or group approach. Patients are encouraged to participate in sports activities that may imitate or substitute specific forms of exercises.

    Systematic review with meta-analysis. To identify risk factors for osteoarthritis (OA) of the knee, hip, and ankle, including joint injury, sport, physical activity, overweight/obesity, and occupational activity, in all age groups. OA is a significant health problem worldwide, affecting up to 10% of men and 18% of women over 60 years of age. There has not been a comprehensive review examining modifiable physical risk factors associated with the onset of OA. This evidence is important to inform the physiotherapy management of individuals following onset of OA. Twelve electronic databases were systematically reviewed. The studies selected met the following criteria: (1) original data; (2) joint injury, sport activity, physical activity, overweight/obesity, and/or occupational activity investigated as risk factors; (3) outcomes included OA (hip, knee, and/or ankle); and (4) analytic component of study design. The data extracted included study design, years of follow-up, study population, OA definition, risk factors, and results (effect estimates reported or calculated where available). The quality of evidence was assessed based on a modified version of the Downs and Black checklist. Joint injury, obesity, and occupational activity were associated with an increased risk of OA of the knee and hip. Sport and physical activity produced inconsistent findings. Joint injury was identified as a significant risk factor for knee OA (combined odds ratio = 3.8; 95% confidence interval: 2.0, 7.2) and hip OA (combined odds ratio = 5.0; 95% confidence interval: 1.4, 18.2), as was previous meniscectomy with or without anterior cruciate ligament injury for knee OA (combined odds ratio = 7.4; 95% confidence interval: 4.0, 13.7). There is a paucity of research examining risk factors associated with ankle OA; this review identified only 2 studies with this outcome. Joint injury, obesity, and occupational activity are associated with an increased risk of knee and hip OA. Some findings

    Full Text Available ICT cause and accelerate the processes of getting and developing knowledge, facilitate the process of modernization of education. Active video games, which involve physical movement of the player’s body, are used to increase the efficiency of perception of the educational material connected with motor activity and to raise the level of motor activity of young people Active video games which require the display of strength, coordination and flexibility are included into the curriculum of physical education, combining physical education with a game. These games use the player’s body movements as a controller, thus providing an alternative to static games and helping to preserve health. The study is the analysis of publications on the use of ICT, namely active video games (exergames in the field of physical culture and sports. The study has found that the use of active video games in educational and training process promotes physical qualities, improves cognitive functions, improves socialization and motivation to exercise. It has been proved that the use of exergames motivation increases motor activity of students and adults. Specially selected exergames help to familiarize students with various types of sports activities, such as those that are difficult to practice in the gym. Rational use of active video games in the classroom optimizes the educational process. Modern mobile exergames on one platform include several sports and can be used outside sports facilities, encouraging more people to exercise. Exergames personalize elements of the game, the level of difficulty, type of physical activity, have a system of evaluation of changes in the user’s preparedness, increase motivation to exercise.

    Multicultural scholarship in sport and exercise psychology should help us understand and apply cultural competencies for all to be physically active. In the present study, two Asian countries, Japan and Singapore, were chosen. The participation rate for physical activities among adolescent girls tends to be lower than that of boys in both countries. Thus, the purpose of the project was to gain knowledge and understanding about sociocultural factors that may explain adolescent girls' perceptions and behaviors toward sport, physical activity, and physical education (PE). A qualitative approach using semi-structured interviews with focus groups was used to understand meanings of physical activity among Buddhist Japanese, and Hindu Indians and Christian Chinese from Singapore. Each focus group consisted of four or five girls and female researchers. Based on the analysis, we created four themes which were "cultural identities," "Asian girls and sport/physical activities," "PE experiences," "motivation for future involvement." The Buddhist Japanese, Hindu Indian, and Christian Chinese participants each reported unique physical activity experiences, and all the participants were aware of how Asian culture may affect being physically active. Experiences of PE classes were similar but perceptions of their PE attire were different for Christian Chinese and Hindu Indian adolescent girls. Based on the results, the importance of nurturing cultural competencies and ways to encourage girls to be physically active throughout life were discussed.

    Glenohumeral translations have been mainly investigated during static poses while shoulder rehabilitation exercises, activities of daily living, and sports activities are dynamic. Our objective was to assess glenohumeral translations during shoulder rehabilitation exercises, activities of daily living, and sports activities to provide a preliminary analysis of glenohumeral arthrokinematics in a broad range of dynamic tasks. Glenohumeral translations were computed from trajectories of markers fitted to intracortical pins inserted into the scapula and the humerus. Two participants (P1 and P2) performed full range-of-motion movements including maximum arm elevations and internal-external rotations rehabilitation exercises, six activities of daily living, and five sports activities. During range-of-motion movements, maximum upward translation was 7.5mm (P1) and 4.7mm (P2). Upward translation during elevations was smaller with the arm internally (3.6mm (P1) and 2.9mm (P2)) than neutrally (4.2mm (P1) and 3.7mm (P2)) and externally rotated (4.3mm (P1) and 4.3mm (P2)). For activities of daily living and sports activities, only anterior translation during reach axilla for P1 and upward translation during ball throwing for P2 were larger than the translation measured during range-of-motion movements (108% and 114%, respectively). While previous electromyography-based studies recommended external rotation during arm elevation to minimize upward translation, measures of glenohumeral translations suggest that internal rotation may be better. Similar amplitude of translation during ROM movement and sports activities suggests that large excursions of the humeral head may be caused not only by fast movements, but also by large amplitude movements.

    Full Text Available Abstract Background There is strong evidence that athletes have a twofold risk for re-injury after a previous ankle sprain, especially during the first year post-injury. These ankle sprain recurrences could result in disability and lead to chronic pain or instability in 20 to 50% of these cases. When looking at the high rate of ankle sprain recurrences and the associated chronic results, ankle sprain recurrence prevention is important. Objective To evaluate the effect of a proprioceptive balance board training programme on ankle sprain recurrences, that was applied to individual athletes after rehabilitation and treatment by usual care. Methods/Design This study was designed as a randomized controlled trial with a follow-up of one year. Healthy individuals between 12 and 70 years of age, who were actively participating in sports and who had sustained a lateral ankle sprain up to two months prior to inclusion, were eligible for inclusion in the study. The intervention programme was compared to usual care. The intervention programme consisted of an eight-week proprioceptive training, which started after finishing usual care and from the moment that sports participation was again possible. Outcomes were assessed at baseline and every month for 12 months. The primary outcome of this study was the incidence of recurrent ankle injuries in both groups within one year after the initial sprain. Secondary outcomes were severity and etiology of re-injury and medical care. Cost-effectiveness was evaluated from a societal perspective. A process evaluation was conducted for the intervention programme. Discussion The 2BFit trial is the first randomized controlled trial to study the effect of a non-supervised home-based proprioceptive balance board training programme in addition to usual care, on the recurrence of ankle sprains in sports. Results of this study could possibly lead to changes in practical guidelines on the treatment of ankle sprains. Results will

    Sports activity increases the risk of maxillofacial fractures. The aim of this study was to analyze trends and characteristics of maxillofacial fractures sustained during sports activity to develop more effective treatments and possibly to prevent injury. Data of 248 patients with maxillofacial fractures sustained during sports activity were retrospectively analyzed based on their clinical records and radiographs. The patients were 226 males (91.1%) and 22 females (8.9%). Their ages ranged from 6 to 70 years and the majority were in their second decade. The fractures were sustained in various sports which included baseball in 85 patients (34.3%), rugby in 40 (16.1%), soccer in 30 (12.1%), softball in 22 (8.9%), golf in 10 (4.0%), hockey in 8 (3.2%), combat sports in 28 (11.3%), and others in 29 (11.7%). The cause of injuries was collision with another player in 97 patients (39.1%), hit by a ball in 89 (35.9%), intended attack in 20 (8.1%), hit by equipment of another player in 15 (6.0%), a fall in 14 (5.6%), and collision with ground equipment in 13 (5.2%). The site of fractures was the mandible in 145 patients (58.5%), midface in 100 (40.3%), and both in 3 (1.2%). Among 210 fracture sites in the mandible, 77 (36.6%) were in the angle, 68 (32.4%) in the symphysis, and 65 (30.9%) in others. Among 103 fractures in the midface, 58 (56.3%) were in the zygoma, 26 (25.2%) in alveolar bone, and 19 (18.4%) in others. Treatment was observation in 67 patients (27.0%), maxillomandibular fixation in 64 (25.8%), open reduction and internal fixation in 63 (25.4%), intramaxillary splinting in 40 (16.1%), transcutaneous reduction in 10 (4.0%), and other procedures in 4 (1.6%). Maxillofacial fractures sustained during sports activity showed characteristic features dependent on the type of sport and cause of injury. This article is protected by copyright.

    The next generation geostationary satellite, GOES-R, will carry two new instruments with unique atmospheric and surface observing capabilities, the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM), to study short-term weather processes. The ABI will bring enhanced multispectral observing capabilities with frequent refresh rates for regional and full disk coverage to geostationary orbit to address many existing and new forecast challenges. The GLM will, for the first time, provide the continuous monitoring of total lightning flashes over a hemispherical region from space. NOAA established the GOES-R Proving Ground activity several years ago to demonstrate the new capabilities of these instruments and to prepare forecasters for their day one use. Proving Ground partners work closely with algorithm developers and the end user community to develop and transition proxy data sets representing GOES-R observing capabilities. This close collaboration helps to maximize refine algorithms leading to the delivery of a product that effectively address a forecast challenge. The NASA Short-term Prediction Research and Transition (SPoRT) program has been a participant in the NOAA GOES-R Proving Ground activity by developing and disseminating selected GOES-R proxy products to collaborating WFOs and National Centers. Established in 2002 to demonstrate the weather and forecasting application of real-time EOS measurements, the SPoRT program has grown to be an end-to-end research to operations activity focused on the use of advanced NASA modeling and data assimilation approaches, nowcasting techniques, and unique high-resolution multispectral data from EOS satellites to improve short-term weather forecasts on a regional and local scale. Participation in the Proving Ground activities extends SPoRT s activities and taps its experience and expertise in diagnostic weather analysis, short-term weather forecasting, and the transition of research and experimental

    Physical activity is important for youth with inflammatory bowel diseases (IBD), and sports participation is a common way in which youth are physically active. Yet, studies examining sports participation in youth with IBD and barriers to sports participation are lacking. This study examined the role of disease complications, body mass index (BMI), subjective physical health, and psychosocial functioning in influencing sports participation in a large sample of youth with IBD participating in the Crohn's and Colitis Foundation of America Partners (CCFA Partners) Kids and Teens Registry. CCFA Partners Kids and Teens is an internet-based cohort study in which participants and their parents self-report demographics, disease characteristics, anthropometrics, and validated assessments of physical health, psychosocial functioning, and perceived impairment in sports participation. We performed a cross-sectional analysis of 450 cohort participants, age 12-17 years. Nearly two-thirds of the sample reported that their IBD resulted in some impairment in sports participation. IBD disease activity was associated with perceived impairment in sports participation. In a forward regression analysis controlling for disease activity, fatigue, pain, and past IBD-related surgery emerged as the most salient correlates of impairment in sports participation. Disease activity and subjective physical health symptoms were the most salient correlates of impairment in sports participation. Whether these barriers interfere with physical activity more generally deserves further study, as does replication of these findings longitudinally. Ultimately, a greater understanding of potential barriers to sports participation may be useful for generating targeted physical activity recommendations for youth with IBD.

    Proprioceptive signals from peripheral mechanoreceptors form the basis for bodily perception and are known to be essential for motor control. However we still have an incomplete understanding of how proprioception differs between joints, whether it differs among the various degrees-of-freedom (DoFs) within a particular joint, and how such differences affect motor control and learning. We here introduce a robot-aided method to objectively measure proprioceptive function: specifically, we systematically mapped wrist proprioceptive acuity across the three DoFs of the wrist/hand complex with the aim to characterize the wrist position sense. Thirty healthy young adults performed an ipsilateral active joint position matching task with their dominant wrist using a haptic robotic exoskeleton. Our results indicate that the active wrist position sense acuity is anisotropic across the joint, with the abduction/adduction DoF having the highest acuity (the error of acuity for flexion/extension is 4.64 ± 0.24°; abduction/adduction: 3.68 ± 0.32°; supination/pronation: 5.15 ± 0.37°) and they also revealed that proprioceptive acuity decreases for smaller joint displacements. We believe this knowledge is imperative in a clinical scenario when assessing proprioceptive deficits and for understanding how such sensory deficits relate to observable motor impairments.

    2015-10-01

    Physical activity and exercise is the mainstay of chronic disease prevention and health maintenance for all people with and without a disability, and clear evidence exists of the benefits among various populations with neurologic disabilities. However, the potential benefits of organized sports for people with neurologic disabilities are not as well explored. In this narrative review, current evidence regarding the impact of organized sports on activity, participation, and quality of life in people with neurologic disabilities of all ages is summarized, and facilitators of and barriers to participation in sports for this population are discussed. The articles reviewed were divided into 2 sets: (1) children and adolescents and (2) adults. The subjects of almost all of the studies were persons with a spinal cord injury. Children and adolescents with a disability who engaged in sports reported self-concept scores close to those of able-bodied athletes, as well as higher levels of physical activity. Adults with a spinal cord injury who engaged in organized sports reported decreased depression and anxiety, increased life satisfaction, and increased opportunity for gainful employment compared with nonathletic persons with disabilities. General facilitators, regardless of age, were fitness, fun, health, competence, and social aspects, whereas overall barriers were lack of or inappropriate medical advice and facilities, decreased self-esteem, poor finances, dependency on others, and views held by others. The importance of this topic for further research is highlighted, and suggestions for future studies are proposed. Copyright © 2015 American Academy of Physical Medicine and Rehabilitation.

    We study the dynamics of a slender inertial swimmer accounting for hydrodynamics, mechanics, muscle activity and sensory feedbacks. Our theory elucidates how elastic properties and proprioception contribute to selecting swimming speed and locomotion gait. Swimmers are shown to take advantage of resonance phenomena to enhance speed and efficiency. Furthermore, we demonstrate how a minimal proprioceptive model, in which the local muscle activation is function of body curvature, is sufficient to exploit hydro-mechanic properties and drive elastic instabilities associated with thrust production. Our results quantitatively agree with live fish experiments and provide a mechanistic basis for the relation U/L ~ f between the swimmer's speed U, length L and tail beat frequency f determined empirically by Bainbridge more than half a century ago.

    Full Text Available Background As a conscious activity of an individual, physical activity (PA constitutes an element of the free-time dimension. The type of goal allows us to distinguish between sport and PA: sport performance vs. psychophysical health. Drawing on the theory of the motivational function of an objective, this study examined the motivational function of an objective in physical activity and sport. Participants and procedures The sample consisted of 2141 individuals: 1163 women aged 16-64 years (M = 23.90, SD = 8.30 and 978 men aged 16-66 years (M = 24.50, SD = 9.40 who completed the Inventory of Physical Activity Objectives (IPAO, which includes the following scales: 1 motivational value, 2 time management, 3 persistence in action, and 4 motivational conflict. There are also questions that allow one to control for variables such as the variety of forms, duration, and frequency of PA, and socio-demographic variables. Results Males presented different motives of physical activity than females. Motives related to shapely body and health were more important for females. The most important motives for males were physical fitness and shapely body. The gender of participants moderates the motivational value of the specific objectives of physical activity and persistence in action. Conclusions With knowledge about the purposefulness of actions, it is possible to support and shape additional motivation experienced by an individual, by setting new, realistic objectives.

    Full Text Available Propriocepção refere-se à percepção dos mecanorreceptores para discriminar a posição do corpo e movimentos articulares, bem como tensões sobre os tendões na fase estática ou dinâmica da marcha. Objetivou-se avaliar por eletromiografia a ativação muscular do gastrocnêmio e tibial anterior em diferentes exercícios de propriocepção do tornozelo em apoio unipodal, comparando graus de dificuldade. Foram selecionados 54 voluntários, sedentários, destros, do sexo masculino (20-35 anos. Exercícios foram feitos no balancinho, prancha de equilíbrio, cama elástica e solo, à razão de três repetições de 15 segundos cada, com intervalo de 15 segundos entre as repetições. Ao final dos testes os voluntários indicaram a maior dificuldade. A atividade elétrica de ambos os músculos foi significativamente maior durante o teste no balancinho. No solo, ambos os músculos apresentaram menor atividade, mas apenas no gastrocnêmio essa diferença foi significativa. No exercício na prancha de equilíbrio e na cama elástica não se encontrou diferença quanto à ativação dos músculos. Na análise intermúsculo foi observada maior atividade do tibial anterior, exceto no balancinho. Assim, para o treino do apoio unipodal na aquisição do ganho proprioceptivo, o equipamento adotado deve ser escolhido com cuidado: no balancinho é maior o recrutamento dos músculos tibial anterior e gastrocnêmio, assim como é maior o grau de dificuldade para manutenção do equilíbrio.Proprioception refers to the ability of mechanoreceptors to discriminate body position and joint movements, as well as tensions during static or dynamic phases. The aim of this study was to assess, by means of surface electromyography, activation patterns of the gastrocnemius and tibialis anterior muscles in proprioception exercises, also comparing difficulty levels.

    To examine the possible effects of physical activity, sports, and restrained eating on the relationship between overweight and absenteeism. Using a web-based lifestyle questionnaire, responses were obtained from 3030 employees in a large banking corporation. These data were then coupled with data from the company's absenteeism register. Physical activity and sports acted as moderator variables in that they both attenuated the positive relationship between overweight and/or obesity and absenteeism. Restrained eating also moderated the relationship between overweight and absenteeism. Remarkably, the degree of overweight was more strongly related to augmented absenteeism in people with higher levels of restrained eating. To reduce absenteeism in overweight employees, it may be beneficial to focus on stimulating physical activity and not on interventions aimed at promoting dieting (restrained eating).

    Medial displacement calcaneal osteotomy with flexor digitorum longus transfer is a common treatment for the management of the adult flatfoot associated with posterior tibial tendon dysfunction. In the literature, there is a paucity of information regarding the ability of patients to return to sport and recreational activities after this surgical procedure. The purpose of this retrospective clinical study was to assess the rate and type of athletic activities that patients participated in before and after medial displacement calcaneal osteotomy with flexor digitorum longus transfer. A consecutive series of 42 patients with a mean age at surgery of 41 years (range 19-74 years) was evaluated with a minimum follow-up of 24 months (range 18-31 months). Pre- and post-operative sporting activities were assessed. At final follow-up, patients were asked to complete a Sports Athlete Foot and Ankle Score (SAFAS). Each patient was also evaluated with weight-bearing radiographs of the foot before surgery and at final follow-up. Preoperatively, 27 of 42 (64.3 %) patients were engaged in athletic activities, participating in an average of 1.4 h/week (range 0-6 h/week); post-operatively, 36/42 (85.7 %) participated in sport and recreational activities for an average of 3.5 h/week (range 0-15 h/week). Meary's angle improved significantly from 11.5 ± 6.2 degrees preoperatively to 7.0 ± 5.7 degrees at final follow-up (p < 0.01); calcaneal pitch improved significantly from 16.5 ± 4.6 degrees to 19.0 ± 5.0 degrees (p < 0.01). At final follow-up, patients demonstrated good SAFASs in symptom tolerance (86.4 %), pain tolerance (89.0 %), daily living performance (96.1 %), and sports performance (86.7 %). The majority of patients returned to sports and recreational activity after medial displacement calcaneal osteotomy and flexor digitorum longus for the treatment of adult flatfoot associated with posterior tibial tendon dysfunction.

    The relationship between sport participation and BMI in children and adolescents is unclear, with some studies showing no association at all and others suggesting that sport is linked to lower BMI. Another possibility, however, is that this relationship is bidirectional, with sport leading to lower BMI but BMI also influencing sport participation. Here, we examine the direction of this association by analyzing a longitudinal dataset. Data come from the Physical Health Activity Study Team (PHAST) study, a prospective open cohort study including 2278 children at baseline, followed from 2004 to 2010. We fit 3 lagged mixed effects models: One examining the simultaneous relationship, one regressing past BMI on present sport participation, and one regressing sport participation on present BMI. Our baseline sample included 1999 children, of whom 50% were female. Mean BMI increased over the study period from 19.0 (SD = 3.7) to 21.2 (SD = 4.1), while organized sport participation declined. Model results showed that BMI and sport are weakly associated, and that each of these variables predicts the other, which generally supports a bidirectional relationship. Consistent with some previous reports, however, the effect size in both directions is very small. At the levels of participation in our sample, activity and BMI are very weakly related. Findings should not obscure the other benefits of physical activity.

    Abstract Objectives Studying the quality of life of people with a spinal cord injury is of great importance as it allows the monitoring of both functioning and adaptation to disability. The aim of this study was to determine the difference between persons with a spinal cord injury involved in sports activities and those not involved in sports activities in relation to their quality of life and the presence of secondary health conditions (pressure ulcers, urinary infections, muscle spasms, osteoporosis, pain, kidney problems-infections, calculosis and poor circulation). Methods The study included a total of 44 participants with spinal cord injury-paraplegia of both genders; 26 of them were athletes and 18 were not athletes. The athletes were training actively for the last two years, minimally 2-3 times per week. A specially designed questionnaire, medical documentation and the Spinal Cord Injury Quality of Life Questionnaire (SCI QL-23) were used for research purposes. Chi-square test was used to analyze the differences between the groups, while multiple analysis of variance (MANOVA) was used to determine the differences between the sets of variables. Results Among the participants, the athletes perceived higher quality of life than the non-athletes (male gender psports activities significantly improves quality of life in the population of people with spinal cord injury-paraplegia. However, sports activities only partially affect secondary health conditions. PMID:27284378

    Established in 2002 to demonstrate the weather and forecasting application of real-time EOS measurements, the Short-term Prediction Research and Transition (SPoRT) program has grown to be an end-to-end research to operations activity focused on the use of advanced NASA modeling and data assimilation approaches, nowcasting techniques, and unique high-resolution multispectral observational data applications from EOS satellites to improve short-term weather forecasts on a regional and local scale. SPoRT currently partners with several universities and other government agencies for access to real-time data and products, and works collaboratively with them and operational end users at 13 WFOs to develop and test the new products and capabilities in a "test-bed" mode. The test-bed simulates key aspects of the operational environment without putting constraints on the forecaster workload. Products and capabilities which show utility in the test-bed environment are then transitioned experimentally into the operational environment for further evaluation and assessment. SPoRT focuses on a suite of data and products from MODIS, AMSR-E, and AIRS on the NASA Terra and Aqua satellites, and total lightning measurements from ground-based networks. Some of the observations are assimilated into or used with various versions of the WRF model to provide supplemental forecast guidance to operational end users. SPoRT is enhancing partnerships with NOAA / NESDIS for new product development and data access to exploit the remote sensing capabilities of instruments on the NPOESS satellites to address short term weather forecasting problems. The VIIRS and CrIS instruments on the NPP and follow-on NPOESS satellites provide similar observing capabilities to the MODIS and AIRS instruments on Terra and Aqua. SPoRT will be transitioning existing and new capabilities into the AWIIPS II environment to continue the continuity of its activities.

    While the positive effect of sports and exercise on physical and psychological well being is well documented within the general population, the effects of sports on the functional ability of a child with mental retardation are limited. To determine if sports activities have been detrimental in improving functional ability in sample of children with mental retardation based in Kolkata, a metropolis in India. Field level study. Six sports associations registered under the Sports Authority of India for training children with mental retardation were shortlisted on the basis of four criteria. From the register, every third name (gender irrespective) belonging to the second (12-15 years) and third (15-21 years) subclasses (out of the four categories laid down in the Special Olympics participation rules) against a constraint of at least two years active attendance in the sports facility for the child was selected. A sample of 31 children was drawn and the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) 12-item version was administered to the caregiver-teacher-coach team of the sample. Relative changes in scores between the point when the survey was conducted and the point when the child joined the sports facility was used as the dependent variable for regression analysis. The number of years in active sports, in school age of the respondent and base score of the children when they joined school were the independent variables. For seven of the WHODAS 2.0 12-item attributes, the number of years in sports activities was found to have a statistically significant effect (p mental retardation. The number of years in school was also another statistically significant factor (p sports activities was a significant factor responsible for improving the functioning of children with mild to moderate mental retardation.

    The importance of the sensorimotor system in maintaining a stable knee joint has been recognized. As individual entities, knee-joint proprioception, landing kinematics, and knee muscles play important roles in functional joint stability. Preventing knee injuries during dynamic tasks requires accurate proprioceptive information and adequate muscular strength. Few investigators have evaluated the relationship between knee proprioception and strength and landing kinematics. To examine the relationship between knee proprioception and strength and landing kinematics. Cross-sectional study. University research laboratory. Fifty physically active men (age = 26.4 ± 5.8 years, height = 176.5 ± 8.0 cm, mass = 79.8 ± 16.6 kg). Three tests were performed. Knee conscious proprioception was evaluated via threshold to detect passive motion (TTDPM). Knee strength was evaluated with a dynamometer. A 3-dimensional biomechanical analysis of a single-legged stop-jump task was used to calculate initial contact (IC) knee-flexion angle and knee-flexion excursion. The TTDPM toward knee flexion and extension, peak knee flexion and extension torque, and IC knee-flexion angle and knee flexion excursion. Linear correlation and stepwise multiple linear regression analyses were used to evaluate the relationships of both proprioception and strength against landing kinematics. The α level was set a priori at .05. Enhanced TTDPM and greater knee strength were positively correlated with greater IC knee-flexion angle (r range = 0.281-0.479, P range = .001-.048). The regression analysis revealed that 27.4% of the variance in IC knee-flexion angle could be accounted for by knee-flexion peak torque and TTDPM toward flexion (P = .001). The current research highlighted the relationship between knee proprioception and strength and landing kinematics. Individuals with enhanced proprioception and muscular strength had better control of IC knee-flexion angle during a dynamic task.

    Anecdotal evidence suggests compression garments (CGs) are being worn underneath normal playing attire during team sports. Wearing CGs as a baselayer could possibly increase heat storage, and so this field study investigated the effects of wearing CGs, comprising knee-length shorts and short-sleeved top underneath normal match-day attire (COMP), versus normal match-day attire alone (NORM) on thermoregulation during simulated team sport activity. Ten match-fit field hockey players twice performed 4x15min exercise bouts consisting of repeated cycles of intermittent, varied-intensity 20m shuttle running (Loughborough intermittent shuttle test), once in COMP and once in NORM. Testing was conducted in an indoor gymnasium (ambient conditions: approximately 17 degrees C, approximately 60% relative humidity). Participants acted as their own controls. Heart rate (HR), 15m sprint time, ratings of perceived exertion (RPE), blood lactate concentration, sweat rate and body core temperature (T(core)) were similar between trials (p>0.05). Mean skin temperature (T(skin)) was significantly higher in COMP than NORM (pteam sport exercise in temperate ambient conditions had no thermoregulatory benefits nor any detrimental effects on T(core), physiological performance or dehydration. However, the higher T(skin) may affect individual preference for wearing CGs as an undergarment during team sports.

    Three systematic reviews were conducted on: (i) the history of mouthguard use in sports; (ii) mouthguard material and construction; and (iii) the effectiveness of mouthguards in preventing orofacial injuries and concussions. Retrieval databases and bibliographies were explored to find studies using specific key words for each topic. The first recorded use of mouthguards was by boxers, and in the 1920s professional boxing became the first sport to require mouthguards. Advocacy by the American Dental Association led to the mandating of mouthguards for US high school football in the 1962 season. Currently, the US National Collegiate Athletic Association requires mouthguards for four sports (ice hockey, lacrosse, field hockey and football). However, the American Dental Association recommends the use of mouthguards in 29 sports/exercise activities. Mouthguard properties measured in various studies included shock-absorbing capability, hardness, stiffness (indicative of protective capability), tensile strength, tear strength (indicative of durability) and water absorption. Materials used for mouthguards included: (i) polyvinylacetate-polyethylene or ethylene vinyl acetate (EVA) copolymer; (ii) polyvinylchloride; (iii) latex rubber; (iv) acrylic resin; and (v) polyurethane. Latex rubber was a popular material used in early mouthguards but it has lower shock absorbency, lower hardness and less tear and tensile strength than EVA or polyurethane. Among the more modern materials, none seems to stand out as superior to another since the characteristics of all the modern materials can be manipulated to provide a range of favourable characteristics. Impact studies have shown that compared with no mouthguard, mouthguards composed of many types of materials reduce the number of fractured teeth and head acceleration. In mouthguard design, consideration must be given to the nature of the collision (hard or soft objects) and characteristics of the mouth (e.g. brittle incisors, more

    The aim of this study was to estimate the effect of being overweight or underweight on proprioception at rest and after muscle damaging eccentric exercise. Twelve lean, 12 overweight, and 8 underweight female participants performed an eccentric exercise session using the knee extensor muscles of the dominant leg. Muscle damage indices and proprioception were assessed up to 3 days postexercise. The results indicated that proprioception at baseline of the lean individuals was superior to that of the other 2 groups. The overweight individuals exhibited a smaller knee joint reaction angle to release than did the lean group, whereas the underweight individuals exhibited a larger reaction angle to release than did the lean group. After eccentric exercise, proprioception was affected more in the overweight and the underweight groups than in the lean group. The greater exercise-induced muscle damage appeared in the overweight group, and the deficient muscle mass of the underweight participants could explain in part the greater disturbances that appeared in proprioception in these 2 groups than for the lean counterparts. In conclusion, deviating from the normal body mass is associated with significant disturbances in the proprioception of the legs at rest and after participation in activities involving eccentric actions.

    Body ownership and agency are fundamental to self-consciousness. These bodily experiences have been intensively investigated using the rubber hand illusion, wherein participants perceive a fake hand as their own. After presentation of the illusion, the position of the participant's hand then shifts toward the location of the fake hand (proprioceptive drift). However, it remains controversial whether proprioceptive drift is able to provide an objective measurement of body ownership, and whether agency also affects drift. Using the virtual hand illusion (VHI), the current study examined the effects of body ownership and agency on proprioceptive drift, with three different visuo-motor tasks. Twenty healthy adults (29.6 ± 9.2 years old) completed VH manipulations using their right hand under a 2 × 2 factorial design (active vs. passive manipulation, and congruent vs. incongruent virtual hand). Prior to and after VH manipulation, three different tasks were performed to assess proprioceptive drift, in which participants were unable to see their real hands. The effects of the VHI on proprioceptive drift were task-dependent. When participants were required to judge the position of their right hand using a ruler, or by reaching toward a visual target, both body ownership and agency modulated proprioceptive drift. Comparatively, when participants aligned both hands, drift was influenced by ownership but not agency. These results suggest that body ownership and agency might differentially modulate various body representations in the brain.

    Physical activity is one of the key determinants of physical, mental, and social health of children and adolescents. Therefore, the early development of health-relevant behavior patterns is of high relevance. To examine the impact of selected socioeconomic factors as well as media consumption, on sports activities and the motor skills of 10- to 14-year-old secondary school students. Body height and body weight were measured. The motor skills were determined with the Deutschen Motorik Test (DMT 6‑18; German Motor Test). Information about media use, media equipment, recreational sports activities, migration status, and the parents' profession was collected by means of a standardized questionnaire. A total of 391 adolescents have been tested (male 235; female 156). Body mass index (BMI) types are evenly distributed on gender. On a weekday, the pupils spend 10.3 h using media (SD ± 9.1 h). On weekends, media use increases up to 12 h per day on average (SD ± 9.7 h). The number of available media is independent from the age of the respondents and the social status of their families. According to bivariate correlations, heavy media use, a high BMI as well as migration status correlate negatively with both sports activities and motor skills. BMI seems to have the strongest influence on athletic performance (b = 0.41). Media use is an important determinant of juvenile sports activity and motor performance, being part of a complex juvenile leisure behavior.

    Shoulder proprioception in patients with glenohumeral osteoarthritis and the effect of total shoulder arthroplasty (TSA) on proprioception have been evaluated previously. Measuring proprioception with an active angle reproduction (AAR) test, proprioception remained unchanged or deteriorated in a short follow-up period after shoulder replacement. Therefore, the purpose of this prospective study was to evaluate the influence of the preoperative Constant score (CS) on postoperative proprioceptive outcome after TSA in patients with primary osteoarthritis to address the question of whether the preoperative state of shoulder function influences postoperative proprioceptive outcome. Twenty-four patients who received total shoulder arthroplasty (TSA) (n = 24) for primary osteoarthritis of the shoulder were enrolled. After retrospectively analyzing the preoperative CS for 120 patients with primary osteoarthritis of the shoulder who received TSA, the patient group was divided into three subgroups according to preoperative functional assessment of the shoulder using the CS. Group one consisted of patients with CS 30). In all patients proprioception was examined 1 day before the operation and 3 months after surgery by 3D motion analysis with an AAR test and also CS. Postoperatively, proprioception in group one (CS proprioception [6.9° (SD 3.3)] was found in the group that had the best preoperative CS (group three, CS > 30). In conclusion, a low preoperative CS is a negative predictive factor for postoperative proprioception after TSA. We should keep that in mind when determining the best timepoint for shoulder replacement in patients with glenohumeral osteoarthritis.

    Single limb stance instability is a risk factor for lower extremity injuries. Therefore, the development of proprioception may play an important role in injury prevention. This investigation considered a professional basketball team for 6 years, integrating systematic proprioceptive activity in the training routine. The purpose was to assess the effectiveness of proprioceptive training programs based on quantifiable instability, to reduce ankle sprains, knee sprains, and low back pain through developing refined and long-lasting proprioceptive control. Fifty-five subjects were studied. In the first biennium (2004-2006), the preventive program consisted of classic proprioceptive exercises. In the second biennium (2006-2008), the proprioceptive training became quantifiable and interactive by means of electronic proprioceptive stations. In the third biennium (2008-2010), the intensity and the training volume increased while the session duration became shorter. Analysis of variance was used to analyze the differences in proprioceptive control between groups, years, and bienniums. Injury rates and rate ratios of injury during practices and games were estimated. The results showed a statistically significant reduction in the occurrence of ankle sprains by 81% from the first to the third biennium (p < 0.001). Low back pain showed similar results with a reduction of 77.8% (p < 0.005). The reduction in knee sprains was 64.5% (not significant). Comparing the third biennium with the level of all new entry players, proprioceptive control improved significantly by 72.2% (p < 0.001). These findings indicate that improvements in proprioceptive control in single stance may be a key factor for an effective reduction in ankle sprains, knee sprains, and low back pain.

    Issue addressed: Recently arrived migrants and refugees from a culturally and linguistically diverse background (CALD) may be particularly vulnerable to social exclusion. Participation in sport is endorsed as a vehicle to ease the resettlement process; however, in Australia, this is often thought as a simple matter of integration into existing sport structures (e.g. clubs). This approach fails to place actual community needs at the centre of sport engagement efforts. Methods: A consultation framework was established with South Australian CALD community leaders and organisations to scope needs for community-based alternatives to participation in traditional sport (e.g. clubs), co-design a suitable community sport program and pilot it in five communities. Interviews and questionnaire surveys were conducted with participants, community representatives, stakeholders and volunteers. Results: Regular, free soccer activities engaged 263 young people from a great variety of nationalities, including over 50% refugees, in secondary state school and community-based sites. Conclusion: Alternative community sport programs can provide a basic but valuable forum to promote physical activity and associated well being in CALD and refugee communities. So what?: Alternative approaches can extend the health benefits of sport participation to disadvantaged children and youth who are excluded from traditional sport participation opportunities.

    Exercise and sports activities can afford mechanical stimuli to the bone and joint tissues which are required to maintain the tissue properties. Moreover, physical exercise is an important part of the management of bone and joint morbidities such as osteoporosis, osteoarthritis, and low back pain. On the other hand, excessive mechanical load involved in exercise and sports activities can be harmful potentially causing overuse injuries of the musculoskeletal tissues. Especially, safety margin for the amount of acceptable mechanical stress is narrow in the elderly due to preexisting musculoskeletal problems. Preparticipation medical checkup and construction of appropriate exercise program based on the physical assessment are mandatory to prevent overload applied to the bone and joint tissues.

    This study aimed to examine the associations of birth weight with ability in school sports in adolescence and participation in leisure-time physical activity (LTPA) across adulthood and to investigate whether associations between birth weight and LTPA change with age. Study participants were British singletons born in 1946 and followed up to age 68 yr (the Medical Research Council National Survey of Health and Development). Birth weights were extracted from birth records. Teacher reports of ability in school sports were collected at age 13 yr. LTPA was self-reported at ages 36, 43, 53, 60-64, and 68 yr and categorized at each age as participating in sports, exercise, and other vigorous LTPA at least once per month versus no participation. Associations were examined using standard and mixed-effects logistic regression models. Relevant data were available for 2739 study participants (50.1% female). When compared with the low birth weight group (≤2.50 kg), those with heavier birth weights were more likely to be rated as above average or average at school sports (vs below average); fully adjusted odds ratio = 1.78 (95% confidence interval = 1.14-2.77). Across adulthood, those with heavier birth weights were more likely to participate in LTPA than those with low birth weight; fully adjusted odds ratio of LTPA across adulthood = 1.52 (95% confidence interval = 1.09-2.14). This association did not vary by age (P = 0.5 for birth weight by age interaction). Low birth weight was associated with lower ability in school sports and with nonparticipation in LTPA across adulthood. Identifying the underlying developmental and social processes operating across life for low birth weight infants may inform the design of appropriate interventions to support participation in LTPA across life.

    Context: Application of cryotherapy modalities is common after acute shoulder injury and as part of rehabilitation. During athletic events, athletes may return to play after this treatment. The effects of cryotherapy on dominant shoulder proprioception have been assessed, yet the effects on throwing performance are unknown. Objective: To determine the effects of a cryotherapy application on shoulder proprioception and throwing accuracy. Design: Single-group, pretest-posttest control session design. Setting: University-based biomechanics laboratory. Patients or Other Participants: Healthy college-aged subjects (n = 22). Intervention(s): Twenty-minute ice pack application to the dominant shoulder. Main Outcome Measure(s): Active joint position replication, path of joint motion replication, and the Functional Throwing Performance Index. Results: Subjects demonstrated significant increases in deviation for path of joint motion replication when moving from 90° of abduction with 90° of external rotation to 20° of flexion with neutral shoulder rotation after ice pack application. Also, subjects exhibited a decrease in Functional Throwing Performance Index after cryotherapy application. No differences were found in subjects for active joint position replication after cryotherapy application. Conclusions: Proprioception and throwing accuracy were decreased after ice pack application to the shoulder. It is important that clinicians understand the deficits that occur after cryotherapy, as this modality is commonly used following acute injury and during rehabilitation. This information should also be considered when attempting to return an athlete to play after treatment. PMID:17597948

    The activity of lecithin: cholesterol acyltransferase (LCAT) and the plasma lipoprotein concentrations of elite athletes from 8 selected sports (volleyball, judo, sprinting, wrestling, throwing, cycling, water polo and tennis) were determined and compared with those of a sedentary control group. Plasma LCAT activity levels in the athletes were significantly 2.2-7.0 times higher than in the controls in most sports (p less than 0.01). Judo, sprinting, wrestling and throwing had comparable LCAT values while tennis, volleyball and cycling were considerably higher. HDL-C concentration was significantly higher than controls in the water polo (p less than 0.05), cycling and volleyball (p less than 0.01) groups. Percentage lipoprotein distribution in the athletes in all sports except tennis, throwing and wrestling were similar to the controls. The differences among groups in LCAT activity may be related to the effect of physical exercise and training adaptations to lipid metabolism. This may be of importance when judging the benefit of exercise for atherosclerosis protection.

    Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.

    Full Text Available The external load of a team-sport athlete can be measured by tracking technologies, including global positioning systems (GPS, local positioning systems (LPS, and vision-based systems. These technologies allow for the calculation of displacement, velocity and acceleration during a match or training session. The accurate quantification of these variables is critical so that meaningful changes in team-sport athlete external load can be detected. High-velocity running, including sprinting, may be important for specific team-sport match activities, including evading an opponent or creating a shot on goal. Maximal accelerations are energetically demanding and frequently occur from a low velocity during team-sport matches.

    To systematically review the relationship between lumbar proprioception and low back pain (LBP). Four electronic databases (PubMed, EMBASE, CINAHL, SPORTDiscus) and reference lists of relevant articles were searched from inception to March-April 2014. Studies compared lumbar proprioception in patients with LBP with controls or prospectively evaluated the relationship between proprioception and LBP. Two reviewers independently screened articles and determined inclusion through consensus. Data extraction and methodologic quality assessment were independently performed using standardized checklists. Twenty-two studies (1203 participants) were included. Studies measured lumbar proprioception via active or passive joint repositioning sense (JRS) or threshold to detection of passive motion (TTDPM). Data from 17 studies were pooled for meta-analyses to compare patients with controls. Otherwise, descriptive syntheses were performed. Data were analyzed according to measurement method and LBP subgroup. Active JRS was worse in patients compared with controls when measured in sitting (standard mean difference, .97; 95% confidence interval [CI], .31-1.64). There were no differences between groups measured via active JRS in standing (standard mean difference, .41; 95% CI, -.07 to .89) or passive JRS in sitting (standard mean difference, .38; 95% CI, -.83 to 1.58). Patients in the O'Sullivan flexion impairment subgroup had worse proprioception than the total LBP cohort. The TTDPM was significantly worse in patients than controls. One prospective study found no link between lumbar proprioception and LBP. Patients with LBP have impaired lumbar proprioception compared with controls when measured actively in sitting positions (particularly those in the O'Sullivan flexion impairment subgroup) or via TTDPM. Clinicians should consider the relationship between sitting and proprioception in LBP and subgroup patients to guide management. Further studies focusing on subgroups, longitudinal

    Knee arthroplasty survival rate - either UKA or TKA - is currently 95%, greater than it was ten years ago, but has not been specifically evaluated in very active patients practicing sport at a high intensity.The terms and conditions of return to physical activities are decided by the surgeon, the rehabilitation or Sports Medicine doctor, who needs to make sure that postoperative rehabilitation has been conducted optimally. Specifically, range of movement must be complete, muscular strengthening has to be sufficient and balance must be recovered by proprioception. Only after this stage (i.e. three to six months after surgery) can physical activities be resumed.Return to sport must be gentle and progressive, with moderate activities limited to short sessions. Progressively the patient will be able to return to intermediate activities, provided that he/she possesses the adequate level of technique for the sport.This up-to-date review for young surgeons and residents aims to provide an informative guide for patients regarding sport following knee arthroplasty.

    The settings approach to health promotion is a world-known concept concerning settings like city, hospital, school, and workplace. The concept has also been used in some regionally specific settings, such as island, prison, or university. However, there are still many, often noninstitutional, settings that have a lot of potential but have not yet been recognized. One of the newcomers is the youth sports club, which has the potential to reach a lot of children and adolescents and is effective, via its casual educational nature based on voluntary participation. According to research, health is an important aim for most youth sports clubs, but it has not been converted into practical actions. Indeed, the clubs often recognize the importance of healthy lifestyles, but there is a lack of understanding of what to do to reinforce it within one's activities. That is why, on the basis of the results of the Health Promoting Sports Club survey in Finland, guidelines for clubs to enhance health promotion as a part of their activities were created. The aim of this article is to present the guidelines, theirs rationale, and practical examples.

    The purpose of this study was to assess participation in sport and physical activity following open reduction and internal fixation of a Lisfranc injury in a cohort of recreational athletes. This study identified all adult patients aged 55 years or younger who presented with a Lisfranc injury and underwent open reduction and internal fixation (ORIF) using a Lisfranc screw combined with bridge plating technique. Sports and physical activity participation was assessed with a new sports-specific, patient-administered questionnaire. Clinical outcomes were assessed with the Foot and Ankle Outcome Score (FAOS). Thirty-three patients qualified for the study (21 men/12 women). Mean age and follow-up were 31.2 (range, 18-55) years and 2.9 (range, 1.5-5.4) years, respectively. Postoperatively, 31 patients (94%) were able to return to some form of sport. Twenty-two patients (66%) returned to playing sport at or above their preinjury level. Of the 11 patients who played less sport, 6 had ongoing pain, and the remaining 5 were asymptomatic but were participating less frequently because of other lifestyle reasons. In addition, of the 33 patients, 11 (33%) had some degree of ongoing pain that might limit their ability to return to sports and physical activities. There was strong correlation between overall FAOS and the Sports Questionnaire. Most patients who sustained a Lisfranc injury could return to sport and physical activity after ORIF. Patients should be counseled preoperatively that about 1 in 3 might experience continued pain at the injury site Level of Evidence: Level IV, retrospective case series.

    Full Text Available ObjectiveTo investigate the effects of a school-based once-a-week sports program on physical fitness, physical activity, and cardiometabolic health in children and adolescents with a physical disability.MethodsThis controlled clinical trial included 71 children and adolescents from four schools for special education [mean age 13.7 (2.9 years, range 8–19, 55% boys]. Participants had various chronic health conditions including cerebral palsy (37%, other neuromuscular (44%, metabolic (8%, musculoskeletal (7%, and cardiovascular (4% disorders. Before recruitment and based on the presence of school-based sports, schools were assigned as sport or control group. School-based sports were initiated and provided by motivated experienced physical educators. The sport group (n = 31 participated in a once-a-week school-based sports program for 6 months, which included team sports. The control group (n = 40 followed the regular curriculum. Anaerobic performance was assessed by the Muscle Power Sprint Test. Secondary outcome measures included aerobic performance, VO2 peak, strength, physical activity, blood pressure, arterial stiffness, body composition, and the metabolic profile.ResultsA significant improvement of 16% in favor of the sport group was found for anaerobic performance (p = 0.003. In addition, the sport group lost 2.8% more fat mass compared to the control group (p = 0.007. No changes were found for aerobic performance, VO2 peak, physical activity, blood pressure, arterial stiffness, and the metabolic profile.ConclusionAnaerobic performance and fat mass improved following a school-based sports program. These effects are promising for long-term fitness and health promotion, because sports sessions at school eliminate certain barriers for sports participation and adding a once-a-week sports session showed already positive effects for 6 months.Clinical Trial RegistrationThis trial was registered with the Dutch Trial Registry (NTR

    Physical activity has a positive impact on people's well-being, and it may also decrease the occurrence of chronic diseases. Activity recognition with wearable sensors can provide feedback to the user about his/her lifestyle regarding physical activity and sports, and thus, promote a more active lifestyle. So far, activity recognition has mostly been studied in supervised laboratory settings. The aim of this study was to examine how well the daily activities and sports performed by the subjects in unsupervised settings can be recognized compared to supervised settings. The activities were recognized by using a hybrid classifier combining a tree structure containing a priori knowledge and artificial neural networks, and also by using three reference classifiers. Activity data were collected for 68 h from 12 subjects, out of which the activity was supervised for 21 h and unsupervised for 47 h. Activities were recognized based on signal features from 3-D accelerometers on hip and wrist and GPS information. The activities included lying down, sitting and standing, walking, running, cycling with an exercise bike, rowing with a rowing machine, playing football, Nordic walking, and cycling with a regular bike. The total accuracy of the activity recognition using both supervised and unsupervised data was 89% that was only 1% unit lower than the accuracy of activity recognition using only supervised data. However, the accuracy decreased by 17% unit when only supervised data were used for training and only unsupervised data for validation, which emphasizes the need for out-of-laboratory data in the development of activity-recognition systems. The results support a vision of recognizing a wider spectrum, and more complex activities in real life settings.

    Controversial results reported in past research pertaining to the effectiveness of sport-based physical activity interventions on weight loss. The purpose of this study was to assess the impact of sport-based physical activity intervention on body weight in children and adolescents using a meta-analysis. Academic Search Complete, Education Source, ERIC, Medline, ProQuest, PsycINFO and SportDiscus databases were searched from January 2000 to April 2015. Eighteen studies met following inclusion criteria: sport-based intervention studies; subjects aged 6-18 years; reported body weight; published in peer-reviewed journals written in English. The mean intervention duration was 17.72 weeks. The overall effect size (ES) was 0.52 (Cohen's d (ES) = 0.52, 95% CI = 0.08, 0.95, P = 0.021), using a random effects model. Moderator analyses results showed that the Q statistic for the sport type (individual sport or team sport, Qbetween (Q b ) = 14.52, df = 1, P = 0.001) and diet control (Qbetween (Q b ) = 8.85, df = 1, P = 0.001), explained the heterogeneity of ESs. Our study showed that there was a moderate overall effect of sport-based physical activity intervention on body weight reduction. The team sport type (ES = 1.05, 95% CI = 0.44, 1.66) and diet control group (ES = 0.84, 95% CI = 0.26, 1.41) appeared to be more effective in reducing body weight.

    To determine whether high-level athletes with patellar tendinopathy have diminished knee proprioceptive acuity. Cross-sectional study. University research laboratory (institutional). Twenty-one basketball and volleyball players with patellar tendinopathy (13 men and 8 women; mean age 24.5 ± 3.6; body mass index = 22.5 ± 2.0 kg/m) and an equal number of athletes without symptoms of patellar tendinopathy injury were included in this study. Participants underwent knee proprioception assessments on a single day. Furthermore, age, sex, height, weight, VISA-P (Victorian Institute of Sport Assessment) questionnaire sports participation, medical history, knee injuries, previous treatment, and medication were obtained. Knee proprioception was evaluated by assessing sense of resistance, using a weight discrimination protocol, and joint position sense (JPS). No significant differences were observed in JPS at 30 and 60 degrees of knee flexion between groups (P = 0.165 and 0.481, respectively). In regard to the ability to discriminate weight, significant differences between the 2 groups were found with the tendinopathy group showing a higher percentage of error (P = 0.009), namely when the set of incremental weights varied by 10% from the standard weight. Athletes with patellar tendinopathy have a diminished perception of force signals required for weight discrimination, whereas JPS remains unaffected in these athletes.

    Proprioceptive neuromuscular facilitation (PNF) is a widely used rehabilitation concept, although its efficacy has not yet been demonstrated in stroke survivors. The aim of this systematic review is to identify, assess and synthesise the potential benefits of using PNF to improve the activities of daily living (ADL) and quality of life (QoL) of individuals with stroke. A systematic electronic search will be conducted in MEDLINE, Embase, CENTRAL and PEDro. We will include randomised or quasi-randomised controlled trials of PNF interventions conducted in stroke survivors up to April 2017. Two review authors will independently select relevant studies and will extract data using the Cochrane handbook for systematic reviews of interventions approach and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). The methodological quality will be assessed by using the PEDro scale. Finally, with the permitted numeric data, we will carry out a meta-analysis. Ethical considerations will not be required. Results will be disseminated in a peer-review journal. This systematic review aims to examine the effects of PNF (neurophysiological approach) in order to clarify its efficacy in improving ADL and QoL in the rehabilitation process of stroke survivors.

    Malignant disease and anticancer therapy dramatically affect daily life activities and participation in grassroots and high-performance sports. Specifically in childhood and adolescence such activities are relevant factors of individual development and social life. This review focuses on the inherent reduction of normal physical activity in pediatric oncology because this cutback additionally contributes to the level of burden of malignancies. Maintaining normality requires detailed analyses of disease-related and therapy-related restrictions and their justification. Relevant efforts should be stepped up to maintain physical activity levels during pediatric cancer therapy. Another aspect addresses direct therapeutic implications. Feasibility studies, nonrandomized as well as randomized investigations addressed therapeutic effects in acute hospital care, in bone marrow transplant settings, and in outpatient therapy. The overall summary shows positive effects on clinical and psychosocial outcome. Even if the basis of the data for children is still limited, there will be no doubt about a general impact of physical activity on acute side effects as well as late effects. In the areas of tension between context-related restrictions, the right to maintain normality wherever possible and the positive therapeutic and psychosocial perspectives of sports, strong efforts are needed to support physical activity wherever indicated, clarify contraindications, and overcome structural limitations.

    The main purpose of this study was to evaluate the differences in adolescents´ objective physical activity levels and perceived effort in physical education, school recess, and extra-curricular organized sport by motivational profiles in physical education. A sample of 102 students 11-16 yr. old completed a self-report questionnaire assessing self-determined motivation toward physical education. Subsequently, students' objective physical activity levels (steps/min., METs, and moderate-to-vigorous physical activity) and perceived effort were evaluated for each situation. Cluster analysis identified a two-cluster structure: "Moderate motivation toward physical education profile" and "High motivation toward physical education profile." Adolescents in the second cluster had higher physical activity and perceived effort values than adolescents in the first cluster, except for METs and moderate-to-vigorous physical activity in extra-curricular sport. These results support the importance of physical education teachers who should promote self-determined motivation toward physical education so that students can reach the recommended physical activity levels.

    Frailty is a common syndrome in older adults characterised by increased vulnerability to adverse health outcomes as a result of decline in functional and physiological measures. Frailty predicts a range of poor health and social outcomes and is associated with increased risk of hospital admission. The health benefits of sport and physical activity and the health risks of inactivity are well known. However, less is known about the role of sports clubs and physical activity in preventing and managing frailty in older adults. The objective of this study is to examine the role of membership of sports clubs in promoting physical activity and reducing levels of frailty in older adults. We used data from waves 1 to 7 of the English Longitudinal Study of Ageing (ELSA). Survey items on physical activity were combined to produce a measure of moderate or vigorous physical activity for each wave. Frailty was measured using an index of accumulated deficits. A total of sixty deficits, including symptoms, disabilities and diseases were recorded through self-report and tests. Direct and indirect relationships between sports club membership, levels of physical activity and frailty were examined using a cross-lagged panel model. We found evidence for an indirect relationship between sports club membership and frailty, mediated by physical activity. This finding was observed when examining time-specific indirect pathways and the total of all indirect pathways across seven waves of survey data (Est = -0.097 [95% CI = -0.124,-0.070], p = sports clubs may be useful in preventing and managing frailty in older adults, both directly and indirectly through increased physical activity levels. Sports clubs accessible to older people may improve health in this demographic by increasing activity levels and reducing frailty and associated comorbidities. There is a need for investment in these organisations to provide opportunities for older people to achieve the levels of physical activity

    As a society we are increasingly concerned about our physical appearance. For example, as much as 24% of people in developed countries admittedly exercise to improve their performance. Professional sportsmen and amateurs alike are in a constant search for new means that will enable them better sport results in shorter time. Among those means, a prominent place belongs to dietary supplements. However, the producers often advertise products whose use in sports is neither scientifically founded nor safe. This brings on an irrational use of herbal supplements which sometimes leads to unwanted side effects, but is more often of little use. Thus, the aim of this review will be to systematically evaluate some of the herbal supplements that are used as adaptogenic and ergogenic aids in sport. The review will include available data on Rhodiola rosea, Withania somnifera, Schisandra chinensis, Tribulus terrestris, Vitis vinifera, Citrus aurantium, and others. Their effects, active ingredients as well as possible adverse effects will be discussed with special focus on clinical studies.

    Full Text Available The new context competence system of vocational training requires the system-creating interdisciplinary link. However, the lack of such interrelation between the humanities, social, economic disciplines and professional subjects badly affects the training results. The quality of training process can be improved by introducing the interdisciplinary principle. In this regard, the authors carried out the research aimed at solving the above problem by developing the method of interdisciplinary correlation and analyzing its system-creating basis.The paper substantiates the possibility of developing students’ technological thinking by means of sports and physical education activity corresponding to a particular professional one according to the universal morphology classification. It is demonstrated that technological thinking can be developed in the context of sports games under several organizational and methodical conditions. One of the proposed conditions concerns the project of a sport game improvement. The given method can find its application in designing the training process related to physical education of students of different profiles.

    The role of exercise therapy in improving pain-related clinical outcomes and trunk muscle activity in patients with chronic low back pain (CLBP) has been widely reported. There is little information on the effect of proprioceptive neuromuscular facilitation (PNF) training in patients with CLBP. The purpose of the present study was therefore to investigate the persistence of the effects of PNF training on pain intensity, functional disability, patient satisfaction, health-related quality of life (HRQOL) and lower back muscle activity in patients with CLBP. Forty-two participants with CLBP were randomly assigned either to 4-week PNF training or to a control group receiving a Low back pain educational booklet. Pain-related outcomes, including pain intensity, functional disability, patient satisfaction, HRQOL and lumbar erector spinae (LES) muscle activity, were measured before and after the intervention, and at a follow-up session 12 weeks after the last intervention session. Compared with the control group, after undergoing a 4-week PNF training intervention, participants showed a significant reduction in pain intensity and functional disability, and improved patient satisfaction and HRQOL (p < 0.01). These effects were still significant at the 12-week follow-up assessment (p < 0.01). LES muscle activity in the PNF training group was significantly increased throughout the measurement periods compared with controls (p < 0.01). The study found that 4-week PNF training has positive long-term effects on pain-related outcomes, and increases lower back muscle activity in patients with CLBP.

    This study examined whether participation in school team sports, exclusively or in combination with other extracurricular activities, is associated with higher levels of psychosocial functioning and healthy behavior than participation in other extracurricular activities alone or nonparticipation. The study sample includes 50,168 ninth grade public school students who completed an anonymous, voluntary statewide survey in 2001. Students were classified into four groups based on their participation in sports and other activities (such as clubs, volunteer work, band, choir, or music lessons): neither, both, other activities only, and sports only. Odds ratios for the group involved in both types of activities were significantly higher than those for all the other groups for all healthy behaviors and measures of connectedness, and significantly lower for all but one of the unhealthy behaviors. Students involved in sports, alone or in combination with other activities, had significantly higher odds than the other two groups for exercise, milk consumption, and healthy self-image, and significantly lower odds for emotional distress, suicidal behavior, family substance abuse, and physical and sexual abuse victimization. Students involved in other activities, alone or in combination with sports, had significantly higher odds than the other two groups for doing homework and significantly lower odds for alcohol consumption, marijuana use, and vandalism. The finding that abuse victims appeared to avoid sports but not other group activities raises concern and merits further research. Considering the potential benefits of participation in sports and other activities, more research is needed to identify and overcome barriers or deterrents, particularly for youth from low-income families.

    Full Text Available Background. It is well known that meniscectomy leads to osteoarthritis of the knee and proprioception impairment. Objective. The aim of this study was to assess retrospectively the joint position sense after meniscal suture and partial medial meniscal resection and to estimate the patients’ satisfaction with knee function. Material and Methods. We evaluated the outcomes of 27 patients after meniscal repair and compared them to those of 24 patients after partial meniscal resection. We estimated the joint position sense at 30°, 45° and 60° of flexion using the Biodex system 4 Pro. All patients were assessed with the IKDC 2000 subjective knee score. Results. A statistically significant worsening in reproducing the injured joint position in comparison to the healthy limb in both groups was observed. These impairments were mostly expressed at 45° and 60° of knee flexion, and were worsening over time in the group of patients who had undergone medial meniscal resection. An average value by the IKDC 2000 scale after 24 months in the meniscorrhaphy group was 76.73 ± 11.17% and 68.93 ± 14.76% after partial medial meniscal resection. Сonclusion. The control over position of the knee is not impaired after meniscal repair. An overall satisfaction with joint function is higher in patients who undergo meniscal suture in comparison to the partial medial meniscal resection group.

    weather research and forecasting ===== The NASA Short-term Prediction Research and Transition (SPoRT) program has numerous modeling and data assimilation (DA) activities in which the WRF model is a key component. SPoRT generates realtime, research satellite products from the MODIS and VIIRS instruments, making the data available to NOAA/NWS partners running the WRF/EMS, including: (1) 2-km northwestern-hemispheric SST composite, (2) daily, MODIS green vegetation fraction (GVF) over CONUS, and (3) NASA Land Information System (LIS) runs of the Noah LSM over the southeastern CONUS. Each of these datasets have been utilized by specific SPoRT partners in local EMS model runs, with select offices evaluating the impacts using a set of automated scripts developed by SPoRT that manage data acquisition and run the NCAR Model Evaluation Tools verification package. SPoRT is engaged in DA research with the Gridpoint Statistical Interpolation (GSI) and Ensemble Kalman Filter in LIS for soil moisture DA. Ongoing DA projects using GSI include comparing the impacts of assimilating Atmospheric Infrared Sounder (AIRS) radiances versus retrieved profiles, and an analysis of extra-tropical cyclones with intense non-convective winds. As part of its Early Adopter activities for the NASA Soil Moisture Active Passive (SMAP) mission, SPoRT is conducting bias correction and soil moisture DA within LIS to improve simulations using the NASA Unified-WRF (NU-WRF) for both the European Space Agency's Soil Moisture Ocean Salinity and upcoming SMAP mission data. SPoRT has also incorporated real-time global GVF data into LIS and WRF from the VIIRS product being developed by NOAA/NESDIS. This poster will highlight the research and transition activities SPoRT conducts using WRF, NU-WRF, EMS, LIS, and GSI.

    Full Text Available In this chapter the author summarises the descriptions of proprioceptive sense from different perspectives. The importance of proprioceptive sense has been shown in developmental psychology, in both the earlier and later stages of individuum formation. The author emphasises in this chapter the role of proprioception as a basis of personality and the individual differences construct. The importance of assessing behaviour at multiple levels has been pointed out by experiments of classic and modern researchers that should include not only verbal tests that would be more important for conscious mental description, but also techniques that could assess other behavioural characteristics, including automatic unconscious and pre-reflexive behaviour. The author also describes the effects of altered proprioception in humans, such as the Pinocchio effect, and other spatial perception distortions. In this chapter the importance of proprioception in acquiring new skills (embodied knowledge as automatic and conditioned reflexive behaviour has also been highlighted. Finally, the complete picture of the individuum has been presented as a multi-layered level of a body-mind union approach.

    Actual and perceived object control (commonly ball) skill proficiency is associated with higher physical activity in children and adolescents. Active video games (AVGs) encourage whole body movement to control/play the electronic gaming system and therefore provide an opportunity for screen time to become more active. The purpose of this study was to determine whether playing sports AVGs has a positive influence on young children's actual and perceived object control skills. Two group pre/post experimental design study. Thirty-six children aged 6-10 years old from one school were randomly allocated to a control or intervention condition. The Test of Gross Motor Development-3 assessed object control skill. The Pictorial Scale of Perceived Competence for Young Children assessed perceived object control skill. The intervention consisted of 6×50min lunchtime AVG sessions on the Xbox Kinect. Two to three sport games were chosen for participants to play each session. General linear models with either perceived object control or actual object control skill as the outcome variables were conducted. Each base model adjusted for intervention status and pre-score of the respective outcome variable. Additional models adjusted for potential confounding variables (sex of child and game at home). No significant differences between the control and intervention groups were observed for both outcomes. This study found that playing the Xbox Kinect does not significantly influence children's perceived or actual object control skills, suggesting that the utility of the Xbox Kinect for developing perceived and actual object control skill competence is questionable.

    Little is known about long-term sporting activity after periosteal autologous chondrocyte implantation (ACI-P) and its correlation to clinical, morphological, and ultrastructural cartilage characteristics on magnetic resonance imaging (MRI). To evaluate long-term sporting activity after ACI-P and to correlate with clinical and MRI findings. Case series; Level of evidence, 4. Patients who underwent ACI-P for isolated cartilage defects of the knee joint between 1997 and 2001 were analyzed for sporting ability for 3 different time points: lifetime until the onset of pain, the year before ACI-P, and 11 years (range, 9.0-13.4 years) postoperatively. Sporting activity was assessed and patients' level of activity scaled using standardized questionnaires. MRI scans of the affected knee joint at follow-up were analyzed using the MOCART (magnetic resonance observation of cartilage repair tissue) score and T2 mapping. Seventy of 86 patients (81% follow-up rate) consisting of 25 female and 45 male patients, with a mean age of 33.3 ± 10.2 years at the time of surgery, mean defect size of 6.5 ± 4.0 cm 2 , and 1.17 treated defects per patient, agreed to participate in the study at a mean 10.9 ± 1.1 years after ACI-P. Fifty-nine patients (69% of total; 84% of follow-up) agreed to MRI, allowing the complete evaluation of 71 transplant sites. Before the onset of symptoms (lifetime), 95.7% of patients played a mean 6.0 sporting activities at a competitive level. In the year before ACI-P, 81.4% of patients played a mean 3.4 sporting activities in 2.4 sessions during 5.4 hours per week at a recreational level. At follow-up, 82.9% of the patients played a mean 3.0 sporting activities in 1.8 sessions during 3.0 hours per week at a recreational level. In contrast to objective factors, 65.6% of the patients felt that their subjective sporting ability had improved or strongly improved after ACI-P, whereas 12.9% felt that their situation had declined or strongly declined, and 21.4% stated

    Full Text Available The proprioception information is a prerequisite for balance, body’s navigation system, and the movement coordinator. Due to changes between the angles of ankle, knee, and hip joints the aforementioned information are important in the coordination of the limbs and postural balance. The aim of this study was to investigate therole of leg and trunk muscles proprioception on static and dynamic postural control. Thirty males students of physical education and sport sciences (age =21.23 ± 2.95 years, height = 170.4 ± 5.1 cm, and weight = 70.7 ± 5.6 kg participated in this study volunteered. Vibration (100HZ was used to disturb of proprioception. Vibrationoperated on leg muscle (gasterocnemius and trunk muscles (erector spine muscle, at L1 level. Leg stance time and Star Excursion Balance Test were used for evaluation of static and dynamic postural control respectively.Subjects performed pre and post (with operated vibration leg stance time and star excursion balance test. Paired sample test used for investigation the effect of vibration on leg and trunk muscles in static and dynamic postural control. Result of this study showed in static postural control, there is no significant difference between pre and post test (operated vibration in leg and trunk muscles (p≤0.05. In contrast there is significant difference indynamic postural control between pre and post test in leg muscles in 8 directions of star excursion balance test (p≤0.05 while there is only significant difference in trunk muscle in antrolateral and lateral of star excursion balance test (p≤0.05. During physical training such conditions like fatigue and injury can disturbproprioceptions’ information. Thus, due to the importance of this information we recommend that coaches'additionally specific trainings any sport used specific exercises to enhance the proprioception information

    We aimed to increase understanding of the link between sport specialization during childhood and adolescent physical activity (PA). The objectives were as follows: (1) describe the natural course of sport participation over 5 years among children who are early sport samplers or early sport specializers and (2) determine if a sport participation profile in childhood predicts the sport profile in adolescence. Participants ( n = 756, ages 10-11 years at study inception) reported their participation in organized and unorganized PA during in-class questionnaires administered every 4 months over 5 years. They were categorized as early sport samplers, early sport specializers, or nonparticipants in year 1 and as recreational sport participants, performance sport participants, or nonparticipants in years 2 to 5. The likelihood that a childhood sport profile would predict the adolescent profile was computed as relative risks. Polynomial logistic regression was used to identify predictors of an adolescent sport profile. Compared with early sport specialization and nonparticipation, early sport sampling in childhood was associated with a higher likelihood of recreational participation (relative risk, 95% confidence interval: 1.55, 1.18-2.03) and a lower likelihood of nonparticipation (0.69, 0.51-0.93) in adolescence. Early sport specialization was associated with a higher likelihood of performance participation (1.65, 1.19-2.28) but not of nonparticipation (1.01, 0.70-1.47) in adolescence. Nonparticipation in childhood was associated with nearly doubling the likelihood of nonparticipation in adolescence (1.88, 1.36-2.62). Sport sampling should be promoted in childhood because it may be linked to higher PA levels during adolescence. Copyright © 2017 by the American Academy of Pediatrics.

  10. Proprioceptive Feedback through a Neuromorphic Muscle Spindle Model

    2017-06-01

    Full Text Available Connecting biologically inspired neural simulations to physical or simulated embodiments can be useful both in robotics, for the development of a new kind of bio-inspired controllers, and in neuroscience, to test detailed brain models in complete action-perception loops. The aim of this work is to develop a fully spike-based, biologically inspired mechanism for the translation of proprioceptive feedback. The translation is achieved by implementing a computational model of neural activity of type Ia and type II afferent fibers of muscle spindles, the primary source of proprioceptive information, which, in mammals is regulated through fusimotor activation and provides necessary adjustments during voluntary muscle contractions. As such, both static and dynamic γ-motoneurons activities are taken into account in the proposed model. Information from the actual proprioceptive sensors (i.e., motor encoders is then used to simulate the spindle contraction and relaxation, and therefore drive the neural activity. To assess the feasibility of this approach, the model is implemented on the NEST spiking neural network simulator and on the SpiNNaker neuromorphic hardware platform and tested on simulated and physical robotic platforms. The results demonstrate that the model can be used in both simulated and real-time robotic applications to translate encoder values into a biologically plausible neural activity. Thus, this model provides a completely spike-based building block, suitable for neuromorphic platforms, that will enable the development of sensory-motor closed loops which could include neural simulations of areas of the central nervous system or of low-level reflexes.

Nowadays way of life causes reduced movement in whole population, such as in preeschool children. Reducing movement in preeschool children can result many postural disturbances and body deformities. In that case it was made systematic medical chackup in children 5-6 years old from ’’Cvrčak’’- Niš kindergarden on food deformities during last seven years (2004-2010. Received results showed desastrous level on food arch, reduced function of food muscules. The idea was that reason for that was childs` reduced body activities, from 2008. year it was made and start to realize the project „komunication and culture in sport“, in regard to grow up sport culture level in children, parents and teachers. As all of us is born having some predispozitions, it was given chance to sport clubs to present to children, teachers and parents all of sport-recreative bases. In cooperation with physical education expert service Office and coatches from sport clubs in Niš, it was made the sport-recreative Project. In one cyclus during one year children are included in next sports: rhythmic gymnastics, judo, tennis, basketball, vollyball, foodball, athledics, skating, skiing. The project gave wonderfull results: a great number of children joined sport clubs, more sport-recreative activities in children, growing right mind about body exercises needs, such as better statistic results after childrens` systematic medical chackup in 2009. and 2010. year.

    Sports medicine is a profession pertaining to primary health care of sport population (competitors, coaches, referees, participants in sports recreation). It embraces the physical and mental health protection and promotion of participants in relation to a particular sport activity and sport environment, directing athletes to a sport and adapting them to sport and the sport to them. Sports medicine takes part in selection procedure, training process planning and programming, and cares for epidemiological, hygienic, nutritional and other problems in sport. The Republic of Croatia belongs to those world states in which the field of sports medicine is regulated neither by a law or by profession. A consequence is that wide circle of physicians and paramedics work in clubs and various medical units without any legal or/and professional control not being adequately educated nor having licence for it. This review is an appeal to the Croatian Medical Chamber and the Ministry of Health to make efforts to promote the education and medical profession in sports medicine.

    Proprioception is essential for planning and controlling limb posture and movement. In our recent work, we introduced a standardized robot-aided method for measuring proprioceptive discrimination thresholds at the wrist to obtain reliable and accurate measures of proprioceptive acuity. Weber's law defines discrimination thresholds as a constant ratio between the just noticeable difference and the reference or standard stimulus. Reporting Weber's fractions thus provides the possibility of comparing results with the reports of others collected worldwide. This work aims to determine that Weber's Law holds for proprioceptive discrimination thresholds and to provide Weber's fraction for wrist joint proprioception. To this end, eight healthy subjects experienced two passive wrist movements of different amplitude and verbally indicated which was larger. An adaptive psychophysical procedure established the amplitude of the largest stimulus according to participants' responses. This comparison stimulus was then compared to a standard stimulus amplitude of 10°, 20°, 30° or 40°. The discrimination thresholds for each standard stimulus were established at the 75% correct response level. The obtained thresholds followed Weber's Law indicating that larger amplitudes were associated with higher discrimination thresholds. Based on a linear regression function the overall Weber's fraction, defined as the slope of the line, was computed to be 0.09. This result expands the present limited knowledge on wrist proprioception showing that its proprioceptive acuity follows Weber's law.

    To evaluate the associations of physical activity and sports team participation with suicidal behavior among U.S. high school students. Data were from the 2003 Youth Risk Behavior Survey (N = 10,530 respondents). Exposure variables included physical activity (inactive, insufficient, moderately intensive, regular vigorously intensive, and frequent vigorously intensive) and sports team participation. Outcome variables were suicide ideation (seriously considering and/or planning suicide) and suicide attempts. Hierarchical logistic regressions were run, controlling for age, race, smoking, alcohol use, drug use, geographic region, unhealthy weight-control practices, and body mass index/weight perceptions. Compared with inactive students or sports team nonparticipants, the odds of suicide ideation were lower among boys reporting frequent vigorous-intensity physical activity (adjusted odds ratio (AOR) = 0.48; 95% confidence interval (CI) = 0.29, 0.79) and sports team participation, respectively (AOR = 0.65; 95% CI = 0.48, 0.86). The odds of suicide attempts were also lower among frequently vigorously active boys (AOR = 0.44; 95% CI = 0.21, 0.96) and sports team participants (AOR = 0.61; 95% CI = 0.40, 0.93). The odds of suicide attempts were lower for regular vigorously active girls compared with inactive girls (AOR = 0.67; 95% CI = 0.45, 0.99) and sports team participants compared with nonparticipants (AOR = 0.73; 95% CI = 0.57, 0.94). Associations with one exposure variable generally weakened when adjustment was made for the other exposure variable, or for feeling sad and hopeless. The association of physical activity and sports team participation with suicide ideation and suicide attempts varied by sex. Further research is needed to clarify these different associations.

    The ability to recognize one's own movement visually is important for motor control and, through attribution of agency, for social interactions. Agency of actions may be decided by comparisons of visual feedback, efferent signals and proprioceptive inputs. Because the ability to identify own visual feedback from passive movements is decreased relative to active movements, or in some cases is even absent, the role of proprioception in self-recognition has been questioned. Proprioception during passive and active movements may, however, differ and so to address any role for proprioception in the sense of agency the active movement condition must be examined. Here we tested a chronically deafferented man (IW) and an age-matched group of 6 healthy controls in a task requiring judgement of the timing of action. Subjects performed finger movements and watched a visual cursor that moved either synchronously or asynchronously with a random delay, and reported whether or not they felt they controlled the cursor. Movement accuracy was matched between groups. In the absence of proprioception, IW was less able than the control group to discriminate self-from computer-produced cursor movement based on the timing of movement. In a control visual discrimination task with concurrent similar finger movements but no agency detection, IW was unimpaired, suggesting that this effect was task specific. We conclude that proprioception does contribute to the visual identification of ownership during active movements and thus to the sense of agency. PMID:17714014

    To elucidate whether extracurricular sports activity during rapid growth correlates with improved bone properties in late adolescence, a longitudinal observation was performed among 96 high-school enrollments (46 boys and 50 girls, born in 1981-1982) in metropolitan Tokyo. In each year of high school, tibial cortical speed of sound (TCSOS) was measured by quantitative ultrasonometry, and participation in extracurricular sports activity (ECSA) since primary school was examined by structured questionnaire. We calculated the number of years since peak height velocity (ysPHV) based on annual records of height from 6 to 18 y of age to indicate progression of puberty. The increase in TCSOS during high school in boys (32.5 m/s) was significantly greater than that in girls (5.4 m/s). The magnitude of positive association between ysPHV and TCSOS attenuated gradually over time. ECSA in grades 7-9 in boys and in grades 4-6 in girls were significant predictors of TCSOS throughout high school, independent of potential confounders. The bone benefits of ECSA around the growth spurt are maintainable in subsequent years. The importance of physical activities that are integrated into the ordinary lifestyle of children and adolescents during this crucial period is emphasized.

    Objective To investigate the feasibility of a knee proprioception evaluation using a dynamometer as a tool for evaluating proprioception of the lower extremities in patients with incomplete spinal cord injury (SCI), and to explore its usefulness in predicting the ambulatory outcome. Methods A total of 14 SCI patients (10 tetraplegic, 4 paraplegic; all AIS D) were included in this study. The passive repositioning error (PRE) and active repositioning error (ARE) were measured with a dynamometer, along with tibial somatosensory evoked potential (SSEP) and abductor hallucis motor-evoked potential (MEP). Ambulatory capacity was assessed with the Walking Index for Spinal Cord Injury II (WISCI-II), both at the time of the proprioception test (WISCI_i) and at least 6 months after the test (WISCI_6mo). Results The PRE showed a negative correlation with WISCI_i (r=-0.440, p=0.034) and WISCI_6mo (r=-0.568, p=0.010). Linear multiple regression showed the type of injury, lower extremities motor score, MEP, and PRE accounted for 75.4% of the WISCI_6mo variance (p=0.080). Conclusion Proprioception of the knee can be measured quantitatively with a dynamometer in patients with incomplete SCI, and PRE was related to the outcome of the ambulatory capacity. Along with the neurological and electrophysiological examinations, a proprioception test using a dynamometer may have supplementary value in predicting the ambulatory capacity in patients with incomplete SCI.

    The purpose of this study was to clarify the effect of colored lenses on visual attributes related to sports activities. The subjects were 24 students (11 females, 13 males; average age 21.0 ±1.2 years) attending a sports university. Lenses of 5 colors were used: colorless, light yellow, dark yellow, light gray, and dark gray. For each lens, measurements were performed in a fixed order: contrast sensitivity, dynamic visual acuity, depth perception, hand-eye coordination and visual acuity and low-contrast visual acuity. The conditions for the measurements of visual acuity and low-contrast visual acuity were in the order of Evening, Evening+Glare, Day, and Day+Glare. There were no significant differences among lenses in dynamic visual acuity and depth perception. For hand-eye coordination, time was significantly shorter with colorless than dark gray lenses. Contrast sensitivity was significantly higher with colorless, light yellow, and light gray lenses than with dark yellow and dark gray lenses. The low-contrast visual acuity test in the Day+Glare condition showed no significant difference among the lenses. In the Evening condition, low-contrast visual acuity was significantly higher with colorless and light yellow lenses than with dark gray lenses, and in the Evening+Glare condition, low-contrast visual acuity was significantly higher with colorless lenses than with the other colors except light yellow. Under early evening conditions and during sports activities, light yellow lenses do not appear to have an adverse effect on visual attributes.

    To describe correlates of physical activity (PA) in structured exercise and structured sports sessions among low-income, overweight children participating in a community-based PA program. A total of 93 children (55% male; 91% Hispanic) aged 8-14 years were included. Participants wore pedometers in a sample of 10 of 59 total sessions offered; mean steps per minute were calculated for structured exercise and sports sessions. Separate multivariable regression models tested associations between steps per minute in exercise and sports sessions and 5 potential correlates: baseline body mass index z-score, aerobic fitness (Progressive Aerobic Cardiorespiratory Endurance Run laps), perceived athletic competence (Harter self-perception profile), sex, and age. Only age (ß = -2.9; P = .02) significantly predicted steps per minute in exercise sessions. Age (ß = -4.3; P = .007), fitness (ß = 0.45; P = .03), and male sex (ß = 8.7; P = .02) significantly predicted steps per minute in sports. In structured exercise and sports, perceived competence may not influence overweight and obese children's PA. However, girls and older or less fit children may engage less actively, especially in sports. Copyright © 2015 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    Sports medicine covers many different aspects, ranging from clinical specialties, such as internal medicine, orthopedics or pediatrics to physiology and sports sciences. The requirements for sports medicine evolve mainly from exercise physiology (elite, leisure and health oriented physical activity), orthopedics and traumatology as well as from preventive and rehabilitative issues. In the new German curriculum, sports medicine is defined as a subspecialty. Historically, sports medicine in Germany has a federal structure with a governing body (Deutsche Gesellschaft für Sportmedizin und Prävention). Due to these facts, University Departments of Sports Medicine (which vary greatly in size and performance) are either attached to Medical or non-Medical Faculties, such as Sports Sciences. In medical schools, sports medicine can be selected as an elective subject. However, the main part of teaching sports medicine is covered by Sports Science Faculties. In an international context, the strength of German sports medicine is its clinical orientation and close cooperation with the sport itself, especially high-performance sports. In the future, like in the Anglo- American countries, sports medicine in Germany will play a major role in health prevention and rehabilitation.

    The authors asked how sport expertise modulates visual field dependence and sensory reweighting for controlling posture. Experienced soccer athletes, ballet dancers, and nonathletes performed (a) a Rod and Frame test and (b) a 100-s bipedal stance task during which vision and proprioception were successively or concurrently disrupted in 20-s blocks. Postural adaptation was assessed in the mean center of pressure displacement, root mean square of center of pressure velocity and ankle muscles integrated electromyography activity. Soccer athletes were more field dependent than were nonathletes. During standing, dancers were more destabilized by vibration and required more time to reweigh sensory information compared with the other 2 groups. These findings reveal a sport skill-specific bias in the reweighing of sensory inputs for spatial orientation and postural control.

    Eighty per cent of severe sports-related central nervous system trauma occurs as a result of collision sports, chiefly American football and rugby union football, followed by wrestling and gymnastics. Although serious head injury is uncommon, episodes of concussion are frequent; repeated concussion should be grounds for suggesting that the athlete give up collision sport. American and rugby union football are the sports mainly responsible for cervical spine injury with resultant quadriplegia.

    The clinical diagnosis and management of patients with sport-related concussion is largely dependent on subjectively reported symptoms, clinical examinations, cognitive, balance, vestibular and oculomotor testing. Consequently, there is an unmet need for objective assessment tools that can identify the injury from a physiological perspective and add an important layer of information to the clinician's decision-making process. The goal of the study was to evaluate the clinical utility of the EEG-based tool named Brain Network Activation (BNA) as a longitudinal assessment method of brain function in the management of young athletes with concussion. Athletes with concussion (n = 86) and age-matched controls (n = 81) were evaluated at four time points with symptom questionnaires and BNA. BNA scores were calculated by comparing functional networks to a previously defined normative reference brain network model to the same cognitive task. Subjects above 16 years of age exhibited a significant decrease in BNA scores immediately following injury, as well as notable changes in functional network activity, relative to the controls. Three representative case studies of the tested population are discussed in detail, to demonstrate the clinical utility of BNA. The data support the utility of BNA to augment clinical examinations, symptoms and additional tests by providing an effective method for evaluating objective electrophysiological changes associated with sport-related concussions.

    Autologous chondrocyte implantation (ACI) has been associated with satisfying results in everyday activities. Clinical results after ACI treatment of femorotibial lesions are superior in comparison with patellofemoral lesions. There is limited information regarding at which level recreational, amateur, and professional athletes can resume sports and physical activities as well as work after ACI and what parameters influence return to work and sports. Return to sports activity and work is dependent on defect characteristics such as location and size. Case series; Level of evidence, 4. A total of 130 patients with isolated full-thickness cartilage defects of the knee joint treated with ACI between June 2000 and October 2007 were retrospectively studied by an established questionnaire that assessed sports-specific questions such as frequency, duration, and intensity. Engagement in 32 different sports disciplines was evaluated. In addition, work-specific data were evaluated according to classifications established by the REFA Association. Results were evaluated depending on patient- and defect-specific parameters. The mean ± SD patient age at ACI was 36.2 ± 9.2 years, with a mean defect size of 4.4 ± 1.7 cm(2). Defects were located at the femorotibial compartment in 55.7% of cases, whereas lesions of the patellofemoral compartment were found in 44.3%. Mean duration of inability to work after ACI was 13.6 ± 11.0 weeks and did not appear to be influenced by patient age. Defect location and defect size did not appear to significantly influence return-to-work rates, but work intensity before surgery significantly influenced return-to-work rates and duration of absence from work. Workplace adaptations were necessary in only 9.2% of cases postoperatively. With regard to postoperative sports activity, 73.1% of patients were able to return to sports. Neither defect location nor size significantly influenced return to physical activity. Patients participated in a mean of 2

    The aim was to compare the effect of a simulated team sport activity circuit (reflective of the activity demands of Australian football) either with or without body 'contact' on muscle soreness, damage, and performance when the circuit was repeated 48 h later. Eleven male, team-sport athletes completed a 'non-contact' (NCON) and a 'contact' (CON) version of the team sport activity circuit in a crossover design with at least 1 week between trials. The effect of CON and NCON on repeated 15m sprint and vertical jump performance was assessed by completing the same version of the circuit 48 h after the initial trial. The effect on perceived soreness and blood markers of muscle damage and inflammation was also determined. Subsequent performance was affected to a greater extent by CON, with both best and mean sprint times significantly slower 48h following CON (psoreness and pressure sensitivity were elevated following both NCON and CON (psoreness was greater with CON (p=0.012). Both CON and NCON resulted in elevated serum creatine kinase, myoglobin and lactate dehydrogenase, while c-reactive protein increased following CON but not NCON. In conclusion, Greater perceived soreness and decrements in performance of the simulated team sport activity circuit when repeated 48 h later were observed following CON.

  14. fMRI and brain activation after sport concussion: a tale of two cases

    Full Text Available Sport-related concussions are now recognized as a major public health concern: The number of participants in sport and recreation is growing, possibly playing their games faster, and there is heightened public awareness of injuries to some high-profile athletes. However, many clinicians still rely on subjective symptom reports for the clinical determination of recovery. Relying on subjective symptom reports can be dangerous, as it has been shown that some concussed athletes may downplay their symptoms. The use of neuropsychological (NP testing tools has enabled clinicians to measure the effects and extent of impairment following concussion more precisely, providing more objective metrics for determining recovery after concussion. Nevertheless, there is a remaining concern that brain abnormalities may exist beyond the point at which individuals achieve recovery in self-reported symptoms and cognition measured by NP testing. Our understanding of brain recovery after concussion is important not only from a neuroscience perspective, but also from the perspective of clinical decision making for safe return-to-play (RTP. A number of advanced neuroimaging tools, including blood oxygen level dependent (BOLD functional magnetic resonance imaging (fMRI, have independently yielded early information on these abnormal brain functions. In the two cases presented in this article, we report contrasting brain activation patterns and recovery profiles using fMRI. Importantly, fMRI was conducted using adapted versions of the most sensitive computerized NP tests administered in current clinical practice to determine impairments and recovery after sport-related concussion. One of the cases is consistent with the concept of lagging brain recovery.

    Philippe M. Tscholl

    2013-09-01

    Full Text Available Patellofemoral instability not only involves lateral patellar dislocation, patellar mal-tracking or subluxation but can also cause a limiting disability for sports activities. Its underlying causes are known as morphological anomalies of the patellofemoral joint or the mechanical axis, femorotibial malrotation, variants of the knee extensor apparatus, and ligamentous insufficiencies often accompanied by poor proprioception. Athletes with such predisposing factors are either suffering from unspecific anterior knee pain or from slightly traumatic or recurrent lateral patellar dislocation Treatment options of patellar instability are vast, and need to be tailored individually depending on the athlete’s history, age, complaints and physical demands. Different conservative and surgical treatment options are reviewed and discussed, especially limited expectations after surgery.

    Full Text Available Brain computer interface (BCI technology has been proposed for motor neurorehabilitation, motor replacement and assistive technologies. It is an open question whether proprioceptive feedback affects the regulation of brain oscillations and therefore BCI control. We developed a BCI coupled on-line with a robotic hand exoskeleton for flexing and extending the fingers. 24 healthy participants performed five different tasks of closing and opening the hand: (1 motor imagery of the hand movement without any overt movement and without feedback, (2 motor imagery with movement as online feedback (participants see and feel their hand, with the exoskeleton moving according to their brain signals, (3 passive (the orthosis passively opens and closes the hand without imagery and (4 active (overt movement of the hand and rest. Performance was defined as the difference in power of the sensorimotor rhythm during motor task and rest and calculated offline for different tasks. Participants were divided in three groups depending on the feedback receiving during task 2 (the other tasks were the same for all participants. Group 1 (n = 9 received contingent positive feedback (participants' sensorimotor rhythm (SMR desynchronization was directly linked to hand orthosis movements, group 2 (n = 8 contingent "negative" feedback (participants' sensorimotor rhythm synchronization was directly linked to hand orthosis movements and group 3 (n = 7 sham feedback (no link between brain oscillations and orthosis movements. We observed that proprioceptive feedback (feeling and seeing hand movements improved BCI performance significantly. Furthermore, in the contingent positive group only a significant motor learning effect was observed enhancing SMR desynchronization during motor imagery without feedback in time. Furthermore, we observed a significantly stronger SMR desynchronization in the contingent positive group compared to the other groups during active and

    Hyperthermia has been shown to affect both central and peripheral nervous systems. However, the consequences of these alterations on the proprioceptive mechanisms underlying human movement control remain unclear. The aim of this study was to investigate the effect of passive hyperthermia on various measures of proprioception and balance, two key components of injury prevention and movement efficiency. After a familiarization session, 14 volunteers (8 males, 6 females) completed two experimental sessions in temperate (CON, 24°C) and hot (HOT, 44°C-50°C) conditions, in a counterbalanced order. Participants were tested for neural function (electrically evoked M-wave and Hoffman reflex, Soleus), active movement discrimination (five positions, 50 trials, dorsiflexion), dynamic balance (Star Excursion Balance Test, three directions), and static balance (single-leg stance). Both rectal (39.0°C ± 0.3°C vs 36.9°C ± 0.6°C) and mean skin (37.9°C ± 1.0°C vs 32.0°C ± 2.7°C) temperatures were significantly higher in HOT than CON (P 0.05) amplitudes, increased the mean error for active movement discrimination (0.58°± 0.13° vs 0.50° ± 0.11°, +17%, P proprioception and balance parameters measured. These observations might be due to heat-induced alterations in efferent and afferent signals to and from the muscle.

    2014-06-01

    Culturally and linguistically diverse (CALD) migrants face significant health risks as they adapt to new cultures. These risks are exacerbated by their limited participation in preventative behaviours such as sports and physical activity. The review aimed to identify studies that examined the correlates of sport and physical activity participation in migrants. The systematic review identified 72 papers, including 6 interventions, 18 qualitative and 48 quantitative studies. The 44 identified correlates highlight the complexities involved in working with migrants. The correlates were grouped in four themes using the social ecological model; acculturation, demographic, psychosocial and environmental/organisational. The social ecological model identified general correlates such as social support and safety. However, there were unique correlates relating to individuals who are facing cultural changes such as acculturation and language. Overall, there is a lack of contextualisation of CALD migrants' sport and physical activity experiences because many studies fail to consider acculturation comprehensively.

    People today are living longer and want to remain active. While obesity is becoming an epidemic, the number of patients suffering from osteoarthritis (OA) is expected to grow exponentially in the coming decades. Patients with OA of the knee are progressively being restricted in their activities. Since a knee arthroplasty (KA) is a well accepted, cost-effective intervention to relieve pain, restore function and improve health-related quality of life, indications are expanding to younger and more active patients. However, evidence concerning return to sports (RTS) and physical activity (PA) after KA is sparse. Our aim was to systematically summarise the available literature concerning the extent to which patients can RTS and be physically active after total (TKA) and unicondylar knee arthroplasty (UKA), as well as the time it takes. PRISMA guidelines were followed and our study protocol was published online at PROSPERO under registration number CRD42014009370. Based on the keywords (and synonyms of) 'arthroplasty', 'sports' and 'recovery of function', the databases MEDLINE, Embase and SPORTDiscus up to January 5, 2015 were searched. Articles concerning TKA or UKA patients who recovered their sporting capacity, or intended to, were included and were rated by outcomes of our interest. Methodological quality was assessed using Quality in Prognosis Studies (QUIPS) and data extraction was performed using a standardised extraction form, both conducted by two independent investigators. Out of 1115 hits, 18 original studies were included. According to QUIPS, three studies had a low risk of bias. Overall RTS varied from 36 to 89% after TKA and from 75 to >100% after UKA. The meta-analysis revealed that participation in sports seems more likely after UKA than after TKA, with mean numbers of sports per patient postoperatively of 1.1-4.6 after UKA and 0.2-1.0 after TKA. PA level was higher after UKA than after TKA, but a trend towards lower-impact sports was shown after both TKA

    Objective. To understand the relationships between participation in different types of leisure time sport activity and adolescent obesity, and how those relationships might differ based on race, gender, and household income. Methods. Data consisted of 6667 students that took part in the 1999 to 2006 National Health and Nutrition Examination Survey. The authors used adjusted Wald tests to examine differences in the prevalence of obesity (body mass index >95th percentile for age and sex) by sport for boys and girls separately. Results. Among adolescent youth age 12 to 19 years, 16.6% of male leisure time sport participants and 15.3% of female sport participants were obese, compared with 23.6% for male nonathlete participant-in-other-activities and 17.0% obesity rate for female nonathlete/participant-in-other-activities. For both males and females, reported participation in leisure time sports decreased between middle school and high school, and this reduction was associated with higher body mass index.

    Osteoarthritis (OA) of the knee is characterized by pain and activity limitations. In knee OA, proprioceptive accuracy is reduced and might be associated with pain and activity limitations. Although causes of reduced proprioceptive accuracy are divergent, medial meniscal abnormalities, which are highly prevalent in knee OA, have been suggested to play an important role. No study has focussed on the association between proprioceptive accuracy and meniscal abnormalities in knee OA. To explore the association between reduced proprioceptive accuracy and medial meniscal abnormalities in a clinical sample of knee OA subjects. Cross-sectional study in 105 subjects with knee OA. Knee proprioceptive accuracy was assessed by determining the joint motion detection threshold in the knee extension direction. The knee was imaged with a 3.0 T magnetic resonance (MR) scanner. Number of regions with medial meniscal abnormalities and the extent of abnormality in the anterior and posterior horn and body were scored according to the Boston-Leeds Osteoarthritis Knee Score (BLOKS) method. Multiple regression analyzes were used to examine whether reduced proprioceptive accuracy was associated with medial meniscal abnormalities in knee OA subjects. Mean proprioceptive accuracy was 2.9° ± 1.9°. Magnetic resonance imaging (MRI)-detected medial meniscal abnormalities were found in the anterior horn (78%), body (80%) and posterior horn (90%). Reduced proprioceptive accuracy was associated with both the number of regions with meniscal abnormalities (P pain, age, gender, body mass index (BMI) and duration of knee complaints. This is the first study showing that reduced proprioceptive accuracy is associated with medial meniscal abnormalities in knee OA. The study highlights the importance of meniscal abnormalities in understanding reduced proprioceptive accuracy in persons with knee OA. Copyright © 2013 Osteoarthritis Research Society International.

Method : 137 youths (82 boys and 55 girls; age 12-13 enrolled in school sport completed two self-report questionnaires- SCOFF for disordered eating and body weight satisfaction- on two separate occasions that were six months apart (T1 vs. T2. Results : Body mass index for age classifications revealed that 5.1% were severely underweight; 1.5% underweight; 88.3% acceptable weight; 4.4% overweight and 0.7% were severely overweight. Conclusions : (i the prevalence of disordered eating was 46% at baseline measurement and this remained stable at 45.3% six months later; (ii there was no sex difference for disordered eating on the two measurement occasions (T1 vs. T2, p>0.05; (iii the prevalence of youths unsure of their bodyweight satisfaction was 26.6-21.2% which compared to 88.3% adjudged to be of healthy weight; across T1 and T2, more male subjects wanted to gain bodyweight while more female subjects wanted to lose bodyweight; and (iv subjects who were dissatisfied with their bodyweight had significantly greater odds of being at risk for developing DE. Holistic education programmes based upon body image and nutrition, are recommended.

    Male fish are susceptible to developing intersex, a condition characterized by the presence of testicular oocytes. In the present study, the relationship between intersex and exposure to estrogenic endocrine active contaminants (EACs) was assessed for 2 genera of sport fish, Micropterus and Lepomis, at 20 riverine sites. Seasonal trends and relationships between EACs and intersex (prevalence and severity) were examined at varying putative sources of EACs throughout North Carolina, identified as point sources, nonpoint sources, and reference sites. Intersex was identified in both genera, which was documented for the first time in wild-caught Lepomis. Intersex was more prevalent (59.8%) and more severe (1.6 mean rank) in Micropterus, which was highly correlation to EACs in sediment. In contrast, intersex was less common (9.9%) and less severe (0.2 mean rank) in Lepomis and was highly correlated to EACs in the water column. The authors found that concentrations of polycyclic aromatic hydrocarbons, polychlorinated biphenyls, industrial EACs, and estrogens were highest at point source sites; however, no source type variation was identified in the prevalence or severity of intersex, nor were there seasonal trends in intersex or EAC concentrations. The authors’ results associate genus-specific prevalence of intersex with specific EAC classes in common sport fishes having biological, ecological, and conservation implications.

    Our baseline sample included 1999 children, of whom 50% were female. Mean BMI increased over the study period from 19.0 (SD = 3.7 to 21.2 (SD = 4.1, while organized sport participation declined. Model results showed that BMI and sport are weakly associated, and that each of these variables predicts the other, which generally supports a bidirectional relationship. Consistent with some previous reports, however, the effect size in both directions is very small. At the levels of participation in our sample, activity and BMI are very weakly related. Findings should not obscure the other benefits of physical activity.

    Of all the most frequent soft tissue disorders of the shoulder, idiopathic frozen shoulder (IFS) offers the greatest potential for studying proprioception. Studies concerning the presence of proprioception dysfunctions have failed to determine the potential for spontaneous healing of passive shoulder stabilizers (anterior and posterior capsule, middle and inferior gleno-humeral ligaments), its relationship with passive (PJPS) and active (AJPS) shoulder proprioception for internal and external rotation (IR, ER), as well as the isokinetic muscle performance of the internal and external rotators. This study investigates these dependencies in the case of arthroscopic release of IFS. The study group comprised 23 patients (average aged 54.2) who underwent arthroscopic release due to IFS and 20 healthy volunteers. The average follow-up time was 29.2 months. The Biodex system was used for proprioception measurement in a modified neutral arm position and isokinetic evaluation. The results were analysed using the T-test, Wilcoxon and interclass correlation coefficient. P-values lower than 0.05 were considered significant. Statistically significant differences were found between involved (I) and uninvolved (U) shoulders only in the cases of PJPS and AJPS, peak torque, time to peak torque and acceleration time for ER (p  0.05) for the U shoulders. The anatomical structure of anterior (capsule, middle and anterior band of inferior gleno-humeral ligament) and posterior (capsule and posterior band of inferior gleno-humeral ligament) passive shoulder restraints has no impact on the difference in PJPS values between ER and IR in a modified neutral shoulder position. The potential for spontaneous healing of the anterior and posterior passive shoulder restraints influences PJPS recovery after arthroscopic release of IFS. ER peak torque deficits negatively affect AJPS values. PJPS and AJPS of ER and IR can be measured with a high level of reproducibility using an isokinetic

    Despite common use of proprioceptive retraining interventions in people with chronic, idiopathic neck pain, evidence that proprioceptive dysfunction exists in this population is lacking. Determining whether proprioceptive dysfunction exists in people with chronic neck pain has clear implications for treatment prescription. The aim of this study was to synthesize and critically appraise all evidence evaluating proprioceptive dysfunction in people with chronic, idiopathic neck pain by completing a systematic review and meta-analysis. MEDLINE, CINAHL, PubMed, Allied and Complementary Medicine, EMBASE, Academic Search Premier, Scopus, Physiotherapy Evidence Database (PEDro), and Cochrane Collaboration databases were searched. All published studies that compared neck proprioception (joint position sense) between a chronic, idiopathic neck pain sample and asymptomatic controls were included. Two independent reviewers extracted relevant population and proprioception data and assessed methodological quality using a modified Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Thirteen studies were included in the present review. Meta-analysis on 10 studies demonstrated that people with chronic neck pain perform significantly worse on head-to-neutral repositioning tests, with a moderate standardized mean difference of 0.44 (95% confidence interval=0.25, 0.63). Two studies evaluated head repositioning using trunk movement (no active head movement thus hypothesized to remove vestibular input) and showed conflicting results. Three studies evaluated complex or postural repositioning tests; postural repositioning was no different between groups, and complex movement tests were impaired only in participants with chronic neck pain if error was continuously evaluated throughout the movement. A paucity of studies evaluating complex or postural repositioning tests does not permit any solid conclusions about them. People with chronic, idiopathic

    Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine associated with disturbed postural control. Cervical proprioception participates in controlling orthostatic posture via its influence on head stabilization. We hypothesized that patients with AIS exhibit altered cervical proprioception. We conducted a case-control study to evaluate cervical proprioception using the cervicocephalic relocation test (CRT) in 30 adolescents with AIS (15.5 ± 1.5 years; Cobb 24.8° ± 9.5°) versus 14 non-scoliotic controls (14.6 ± 2.0 years). CRT evaluates cervical proprioception by measuring the capacity to relocate the head on the trunk after active rotation of the head in the transversal plane without visual control. Each subject performed ten right and then ten left head rotations. The CRT results were pathological in 12 AIS patients (40 %). The CRT mean was significantly different between AIS patients with a pathological CRT (5° ± 1.4° for right rotation; 4.2° ± 0.9° for left rotation) compared with AIS patients with a normal CRT (2.7° ± 0.6° for right rotation; 2.9° ± 0.8° for left rotation) or with the control group (3.5° ± 2.1° for right rotation; 3.1° ± 1.2° for left rotation). Cervical proprioception is impaired in certain AIS patients. This anomaly may worsen the prognosis of AIS (headache; balance disorders; worsened spinal deformity; complication after spinal fusion). We recommend systematic screening for altered cervical proprioception in AIS patients.

  3. The role of differential delays in integrating transient visual and proprioceptive information

    Full Text Available Many actions involve limb movements towards a target. Visual and proprioceptive estimates are available online, and by optimally combining (Ernst and Banks, 2002 both modalities during the movement, the system can increase the precision of the hand estimate. The notion that both sensory modalities are integrated is also motivated by the intuition that we do not consciously perceive any discrepancy between the felt and seen hand’s positions. This coherence as a result of integration does not necessarily imply realignment between the two modalities (Smeets et al., 2006. For example, the two estimates (visual and proprioceptive might be different without either of them (e.g. proprioception ever being adjusted after recovering the other (e.g. vision. The implication that the felt and seen positions might be different has a temporal analog. Because the actual feedback from the hand at a given instantaneous position reaches brain areas at different times for proprioception and vision (shorter for proprioception, the corresponding instantaneous unisensory position estimates will be different, with the proprioceptive one being ahead of the visual one. Based on the assumption that the system integrates optimally and online the available evidence from both senses, we introduce a temporal mechanism that explains the reported overestimation of hand positions when vision is occluded for active and passive movements (Gritsenko et al., 2007 without the need to resort to initial feedforward estimates (Wolpert et al., 1995. We set up hypotheses to test the validity of the model, and we contrast simulation-based predictions with empirical data.

    The article explores the process of "sportification"--i.e., processing physical activity in a sport regulated by a set of rules and standards, legitimized by supervisory institutions--from two originals practices, parkour and urban golf. To study these practices, we crossed the contributions of urban sociology and of the contemporary sociology of sport while respecting the methodological principles of qualitative sociology. A first point concerns the process of"sport" itself, its definition, its various stages, and the role played by communication of stakeholders on public space. The cultural mediation shows us how to institutionalize the movement that represents the "sports" resulted in the same time reconfiguration of physical practices themselves. Recent events illustrate the ongoing reconfiguration, we will detail them. Finally, we show the effects produced by the process on the definition of urban culture and sports: setting sight of activities, enhanced cooperation with the media-cultural, polarization between different types of practical in the case of parkour, around a confrontation between two of the founders.

    The present study identified adolescents' motor competence (MC)-based profiles (e.g., high actual and low perceived MC), and accordingly investigated differences in motivation for physical education (PE), physical activity (PA) levels, and sports participation between profiles by using regression analyses. Actual MC was measured with the Körperkoordinationstest für Kinder. Adolescents (n = 215; 66.0% boys; mean age = 13.64 ± .58 years) completed validated questionnaires to assess perceived MC, motivation for PE, PA-levels, and sports participation. Actual and perceived MC were only moderately correlated and cluster analyses identified four groups. Two groups of overestimators (low - overestimation, average - overestimation) were identified (51%), who particularly displayed better motivation for PE when compared to their peers who accurately estimated themselves (low - accurate, average - accurate). Moreover, adolescents with low actual MC, but high perceived MC were significantly more active than adolescents with low actual MC who accurately estimated themselves. Results pointed in the same direction for organised sports participation. Underestimators were not found in the current sample, which is positive as underestimation might negatively influence adolescents' motivation to achieve and persist in PA and sports. In conclusion, results emphasise that developing perceived MC, especially among adolescents with low levels of actual MC, seems crucial to stimulate motivation for PE, and engagement in PA and sports.

    Both female athletes' participation in soccer and associated injuries have greatly increased in recent years. One issue is the 2-9 times greater incidence of noncontact anterior cruciate ligament (ACL) injuries in female athletes relative to male athletes in comparable sports. Several factors such as limb dominance and sporting history have been proposed to play a role in ACL incidence rates between male and female athletes. However, evidence about the effects of these factors and how they interact with sex is mixed, and thus no consensus exists. To quantify the effects of sports participation, limb dominance, and sex on dynamic postural control and knee-joint proprioception. Cross-sectional study. University research laboratory. 19 male soccer players, 17 female soccer players, 19 sedentary men, and 18 sedentary women. Joint-position sense was tested using reproduction of passive positioning on a Biodex isokinetic dynamometer (30°, 45°, and 60° from 90° of knee flexion). Three Star Excursion Balance Test directions were used to assess dynamic postural control. Normalized reach distance (% of leg length) in the anterior, posteromedial, and posterolateral directions on each leg quantified dynamic postural control. Average absolute error and constant error for both limbs quantified joint-position sense. Posteromedial reach distance was significantly better in soccer players than sedentary individuals (P = .006). Anterior reach distance was significantly better (P = .04) in sedentary individuals than soccer players. No limb-dominance or sex differences were identified for dynamic postural control, and no differences in absolute- or constant-error scores were identified. Sporting history has a direction-specific impact on dynamic postural control. Sporting history, sex, and limb dominance do not influence knee-joint proprioception when tested in an open kinetic chain using passive repositioning.

    Full Text Available Purpose: The objective of this article is to know if there are differences in the variables that explain the entrepreneurial intention of the Physical Activity and Sport Science students addressing academic training and gender of them. Design/methodology/approach: To know entrepreneurial intentions and the different variables related to entrepreneurship, a questionnaire previously validated was used. The questionnaire was provided to 578 students pre-graduated (1st-4th course and post-graduate of Physical Activity and Sport Science degree of Valencia. Findings: Statistically significant differences (p ≤ 0.05 in the variables that predict entrepreneurial intention of Physical Activity and Sport Science students by gender and training were found. In both genders, the attitude towards entrepreneurship and the perceived behavior control were the predictors of entrepreneurial intentions and in men also the subjective norms. Research limitations/implications: The students sample belongs only to the Physical Activity and Sport Science degree of Valencia, so the results cannot be extrapolated to the entire population. Practical implications: It should be developing the attitude toward the behavior of entrepreneurship and perceived behavioral control to promote entrepreneurship. In this way, the graduates will be more prepare for insertion into the working world. Social implications: To increase the number of entrepreneurs (male and female in the sports sector throughout the education, reducing the gender gap in entrepreneurship and improve the quality of entrepreneurship, as this is a key issue because of the positive impact that this phenomenon generates on the economy Originality/value: It is interesting to know the predictor variables of entrepreneurial intentions, and to know if there are differences based on education and gender due to the massive entry of women into the sport workplaces and low intention to undertake of the.

    Youth participation in organised sport and physical activity is important for healthy development, growth and wellbeing. In 2014, Active Healthy Kids Australia released its inaugural Report Card on Physical Activity for Children and Young People, which synthesised the best available national- and state-level data for children and young people (Sport from the 2014 Report Card, compares Australia's Organised Sport grade with other countries, identifies future directions for research and surveillance, and explores possible beneficial strategies. The Report Card highlighted that between 64% and 85% of Australians aged 5-17 years participate in organised sports, a rate higher than alternate forms of physical activity such as active transportation, active play and school based physical activity. This finding reflects Australia's position as one of the global leaders for participating in organised sport. Future research and surveillance methodologies however, need to incorporate standardised metrics that aim to capture more detailed data regarding organised sport participation. Facilitating access for all children and preventing dropout from organised sports are important initiatives to improve current levels of sport participation. However, given that 80% of Australians aged 5-17 years are not sufficiently physically active to achieve the daily recommendation, participation in sport alone is not enough to ensure that children can accrue the health benefits associated with being physically active. As such, there is a pressing need to develop strategies that engage children in other forms of physical activity such as active transportation and active play.

    2017-11-01

    This study examines the role of regional government quality in health-related participation in sport and physical activity among adults (18-64 years) in 28 European countries. The importance of the analysis rests in the relative autonomy that regional and local governments have over policy decisions connected with sport and physical activity. While existing studies have focussed on economic and infrastructural investment and expenditure, this research investigates the quality of regional governments across 208 regions within 28 European countries. The individual-level data stem from the 2013 Eurobarometer 80.2 (n = 18,675) and were combined with regional-level data from Eurostat. An individual's level of participation in sport and physical activity was measured by three variables reflecting whether an individual's activity level is below, meets, or exceeds the recommendations of the World Health Organization. The results of multi-level analyses reveal that regional government quality has a significant and positive association with individual participation in sport and physical activity at a level meeting or exceeding the guidelines. The impact is much larger than that of regional gross domestic product per capita, indicating that regional disadvantage in terms of political quality is more relevant than being disadvantaged in terms of economic wealth.

    Physical activity levels in most affluent countries are low and many people do not meet the current recommendations. Particularly for people with a low income, economic strategies seem promising to stimulate taking part in sports activities. This study investigated the importance of economic restraints for taking part in sports activities as well as perceptions of low-income people toward different pricing interventions. A qualitative study was conducted, using semistructured, individual interviews with 27 low-income men and women. The framework approach was used to analyze the transcripts of the interviews. The respondents considered finances to be an important barrier for participating in sports activities, together with some individual barriers. Promising pricing strategies are a discount on the subscription to the fitness or sports club, a 1 month free trial, and free entrance to the swimming pool once a week. Pricing strategies may be a promising intervention to increase physical activity levels of low-income people. However, this study indicates that this should be coupled with an intervention directed at individual barriers. Some pricing strategies will be used and appreciated more by low-income people than other pricing strategies. In addition, pricing strategies should be tailored to individual needs and preferences.

    This prospective study evaluated the development of proprioception over the course of 3 years after shoulder arthroplasty. Twenty-one patients were enrolled who underwent total shoulder arthroplasty (n = 10) or hemiarthroplasty (HEMI) (n = 11) for shoulder osteoarthritis. All patients were examined 1 day before the operation, 6 months and 3 years after surgery in a motion analysis study with an active angle-reproduction (AAR) test. Overall proprioception measured by the AAR deteriorated significantly 3 years after surgery [from 6.6° (SD 3.1) to 10.3° (SD 5.7); p = 0.017] and was significantly worse than in the control group [10.3° (SD 5.7) vs. 7.8° (SD 2.3); p = 0.030). In the HEMI subgroup, 3 years after shoulder replacement, there is a significant deterioration of proprioception at 30° of external rotation [from 3.1° (SD 3.5) to 12.8° (SD 10.7); p = 0.031]. On average, in the TSA subgroup proprioception deteriorated from 7.1° (SD 3.1) to 8.6° (SD 1.4) and in the HEMI subgroup from 6.1° (SD 2.1) to 12.4° (SD 8.3). The comparison of postoperative impairment of proprioception between the TSA and HEMI subgroup showed significantly worse proprioception for the HEMI subgroup at 30° of external rotation [9.8° (SD 10.1) vs. 1.6° (SD 6.3) in the TSA group; p = 0.046]. In conclusion, proprioception that was measured by an AAR test remained unchanged or deteriorated 3 years after shoulder arthroplasty. The postoperative deterioration of proprioception was more distinctive in HEMI than in TSA group.

    Proprioception can be assessed by measuring joint position sense (JPS). Most studies have focused on JPS of the knee joint while literature for other joints especially for hip JPS is scarce. Although some studies have evaluated proprioception of the knee joint, the reproducibility of methods has rarely been investigated. To estimate intrasession reliability and agreement of an active-active JPS test for hip flexion/abduction and knee flexion in healthy older adults. Nineteen healthy older adults participated in this study. The proprioception of the hip (flexion and abduction) and knee (flexion) were assessed in both legs using the "active-active" reproduction technique. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and limits of agreement (LOA) were estimated for relative angular error (RE), absolute angular error (AE), and variable angular error (VE). Reliability of our JPS test was substantial to almost perfect for the RE for both joints and legs (ICC values ranging from 0.75 to 0.93). We also found that the ICC values for AE were substantial for knee flexion and hip abduction of the left and right leg. The ICC results of VE showed poor reliability for hip and knee joints. SEM and LOA values for hip abduction were generally lower than for hip and knee flexion, indicating lower measurement error or more precise scores for the proprioception test of hip abduction. Proprioceptive acuity of the knee and hip joints in healthy older adults can be reliably assessed with an active-active procedure in a standing position with respect to relative and absolute error.

    Full Text Available Participation in regular moderate aerobic physical activity and increased physical fitness is associated with a decrease in cardiovascular mortality, which is after the age of 35 most often due to coronary events. On the other hand, moderate and vigorous physical exertion is associated with an increased risk for cardiac events, including sudden cardiac death in individuals harbouring cardiovascular disease. The risk-benefit ratio may differ in relation to the individual's age, fitness level and the presence and type of cardiovascular disease.The latest position stand of the European association of Cardiovascular Prevention and Rehabilitation on cardiovascular evaluation in middle aged/senior individuals, who are contemplating exercise or who are already engaged in nonprofessional competitive or recreational leisure sporting activity, is presented in the article. The aim of recommendations is to evaluate and encourage as many individuals as possible to participate in regular physical activity while minimizing the risk of cardiovascular adverse events. Recommendations are based on the individual's risk profile and the intended level of physical activity. Because of the large size of the population, an initial self assessment through health questionaire is proposed, relating to symptoms, risk factors for coronary artery disease and habitual exercise level. For those with positive self-assessed risk profile and those willing to perform high-intensity activities, a further risk stratification/evaluation should be performed by a qualified physician. In individuals with an increased risk for coronary events, maximal exerise is advocated and then further (cardiological evaluation when needed.

To evaluate and classify children and young people as to physical aptitude related to health through scientifically validated indicators and to relate them to socioeconomical condition. To verify compatibility between qualitative and quantitative researches. The sample of the qualitative study is composed of 22 subjects, characterizing itself as a non probabilistic sample of the causal type. Semi structured interview techniques in an individual situation and free evocation of words were used, based on the presuppositions of the Theory of Social Representations. A mixed sample, of the quantitative study, is composed of 67 children, where the possibility of relationship of the family income variable was confirmed with the variables: Body Composition and Flexibility, that compose the physical aptitude indicator related to health and the social representation of the parents. The qualitative results refer to biological aspects of health that constitute the central nucleus of the social representation of sport. In the quantitative aspect, it is verified that there was no correlation statistically, significant between the indexes of physical aptitude and the family income. The reason attributed to the physical-sport activities by the parents or relatives of the children, is based on the benefits to biological health and is shown by the children's good performance in the applied aptitude tests. There is not significant correlation between the index of physical aptitude applied to health, which reinforces the possibility of the parents social representation and the children's behavior.

    Adventure and extreme sports often involve unpredictable and inhospitable environments, high velocities, and stunts. These activities vary widely and include sports like BASE jumping, snowboarding, kayaking, and surfing. Increasing interest and participation in adventure and extreme sports warrants understanding by clinicians to facilitate prevention, identification, and treatment of injuries unique to each sport. This article covers alpine skiing and snowboarding, skateboarding, surfing, bungee jumping, BASE jumping, and whitewater sports with emphasis on epidemiology, demographics, general injury mechanisms, specific injuries, chronic injuries, fatality data, and prevention. Overall, most injuries are related to overuse, trauma, and environmental or microbial exposure. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available This study assessed whether numerical magnitude affects the setting of basic spatial coordinates and reference frames, namely the subjective straight ahead. Three tasks were given to 24 right-handed healthy participants: a proprioceptive and a visuo-proprioceptive task, requiring pointing to the subjective straight ahead, and a visual task, requiring a perceptual judgment about the straight ahead position of a light moving left-to-right, or right-to-left. A control task, requiring the bisection of rods of different lengths, was also given. The four tasks were performed under conditions of passive auditory numerical (i.e., listening to small, 2, and large, 8, numbers, and neutral auditory-verbal (blah stimulation. Numerical magnitude modulates the participants’ deviations in the visual straight ahead task, when the movement of the light is from left to right, with the small number bringing about a leftward deviation, the large number a rightward deviation. This result suggests that the spatial effects induced by the activation of the mental number line extend to an egocentric frame of reference. A similar directional modulation was found in the rod bisection task, in line with previous evidence. No effects of numerical magnitude were found on the proprioceptive and visuo-proprioceptive straight ahead tasks. These results suggest that the spatial effects induced by the activation of the mental number line extend to an egocentric frame of reference but only when a portion of horizontal space has to be actively explored.

    Slowing the decline in participation in physical activity among adolescent girls is a public health priority. This study reports the outcomes from a multi-component school-based intervention (Girls in Sport), focused on promoting physical activity among adolescent girls. Group randomized controlled trial in 24 secondary schools (12 intervention and 12 control). Assessments were conducted at baseline (2009) and at 18 months post-baseline (2010). The setting was secondary schools in urban, regional and rural areas of New South Wales, Australia. All girls in Grade 8 in 2009 who attended these schools were invited to participate in the study (N = 1769). Using a Health Promoting Schools and Action Learning Frameworks, each school formed a committee and developed an action plan for promoting physical activity among Grade 8 girls. The action plan incorporated strategies in three main areas - i) the formal curriculum, ii) school environment, and iii) home/school/community links - based on the results of formative data from target girls and staff and on individual needs of the school. A member of the research team supported each school throughout the intervention. The main outcome measure was accelerometer-derived total physical activity (TPA) spent in physical activity. Data were analyzed from December 2011 to March 2012. 1518 girls (mean age 13.6y ±0.02) were assessed at baseline. There was a significant decline in TPA from baseline to 18-month follow-up with no differences between girls in the intervention and control schools. Only one-third of schools (4/12) implemented the intervention as per their action plan. Per-protocol analyses on these schools revealed a smaller decline in percentage of time spent in MVPA among girls in the intervention group (adjusted difference 0.5%, 95% CI = -0.01, 0.99, P = 0.05). The Girls in Sport intervention was not effective in reducing the decline in physical activity among adolescent girls. Lack of implementation by most

    To determine the association between youth sport team participation and dietary behaviors among elementary school-aged children. Cross-sectional survey. Public schools in Texas during 2009-2010. A total of 5035 ethnically diverse fourth graders. Participation in organized sports teams, consumption of select food items (fruits, vegetables, beverages, sweets/snacks). Multiple logistic regression was used to assess the association between each food item (eaten at least once on the previous day) and number of sports teams as the independent class variable (0, 1 ,2, ≥3), adjusting for body mass index physical activity, socioeconomic status, and ethnicity. Significant dose-response associations were observed between number of sports teams and consumption of fruits and vegetables. For boys, the likelihood of eating fruit and fruit-flavored drinks was significantly higher and the odds of drinking soda were lower with the number of teams. For girls, the likelihood of consuming green vegetables increased as sports teams participation increased, and participation was positively associated with diet soda consumption. A positive association was observed between the number of sports teams and scores on the Healthy Food Index for boys and girls. The findings that sports participation is associated with consumption of fruits and vegetables and lower consumption of soda suggest that efforts should be focused on supporting youth team sports to promote healthier food choices. Since sports are available to all ages, sports may be an important venue for promoting healthier dietary behaviors.

    Video gaming as a therapeutic tool has largely been studied within the stroke population with some benefits reported in upper limb motor performance, balance, coordination, and cardiovascular status. To date, muscle activation of upper limb muscles in persons with spinal cord injuries (SCI) has not been studied during video game play. In this paper, we provide descriptive and comparative data for muscle activation and strength during gaming for players with tetraplegia and paraplegia, as well as, compare these results with data from traditional arm exercises (ie, biceps curl and shoulder press) with light weights which are commonly prescribed for a home program. Fourteen individuals with chronic SCI (9 tetraplegia, 5 paraplegia). We measured upper limb muscle activation with surface electromyography (EMG) during Wii Sports video game play. Muscle activation was recorded from the playing arm during 4 selected games and normalized to a maximum voluntary contraction (MVC). Heart rate and upper limb motion were recorded simultaneously with EMG. Wilcoxon signed rank tests were used to analyze differences in muscle activation between participants with paraplegia versus tetraplegia and compare gaming with traditional arm exercises with light weights. A Friedman 2-way analysis of variance identified key muscle groups active during game play. Overall muscle activation across the games was not different between those with paraplegia and tetraplegia. Heart rate during video game play for tennis and boxing were on average 10 to 20 beats/minute above resting heart rate. The magnitude of EMG was relatively greater for traditional arm exercises with light weights compared with game play. The selected Wii games were able to elicit upper extremity muscle activation and elevated heart rates for individuals with SCI that may be used to target therapeutic outcomes.

    Somatosensation plays a critical role in the dexterous manipulation of objects, in emotional communication, and in the embodiment of our limbs. For upper-limb neuroprostheses to be adopted by prospective users, prosthetic limbs will thus need to provide sensory information about the position of the limb in space and about objects grasped in the hand. One approach to restoring touch and proprioception consists of electrically stimulating neurons in somatosensory cortex in the hopes of eliciting meaningful sensations to support the dexterous use of the hands, promote their embodiment, and perhaps even restore the affective dimension of touch. In this review, we discuss the importance of touch and proprioception in everyday life, then describe approaches to providing artificial somatosensory feedback through intracortical microstimulation (ICMS). We explore the importance of biomimicry--the elicitation of naturalistic patterns of neuronal activation--and that of adaptation--the brain's ability to adapt to novel sensory input, and argue that both biomimicry and adaptation will play a critical role in the artificial restoration of somatosensation. We also propose that the documented re-organization that occurs after injury does not pose a significant obstacle to brain interfaces. While still at an early stage of development, sensory restoration is a critical step in transitioning upper-limb neuroprostheses from the laboratory to the clinic. Copyright © 2014 Elsevier Inc.

    2014-06-01

    Sport is becoming increasingly more important in our society. Due to the changing age spectrum with a greater number of elderly and substantially more active people, an increasing number of people with underlying orthopedic diseases are becoming interested in participating in sport. This article deals with the possibilities and effects of sporting activities for people with rheumatoid arthritis within the framework of a conservative therapy. A literature search was carried out using medical search engines, in particular PubMed, and also via the recommendations of specialist societies and patient help groups. The quality of life of patients with rheumatoid arthritis consists of physical, mental and social components. Sport as a means of rehabilitation influences all of these components. Sport should be comprehended as a form of therapy and be adapted to the needs of the individual patient. The willingness to actively participate in sport should always be highly rated and encouraged. Sport is therefore an important pillar of therapy in a conservative total concept. The main aspects of sport therapeutic activities are functional, pedagogical and experience-oriented aspects. The clinical symptoms, extent of damage and physical impairment must, however, be evaluated and taken into consideration for the therapeutic concept. The amount of data on the complex topic of sport and rheumatoid arthritis is low and is mainly dealt with as retrospective reviews. A prospective randomized study basis is lacking. The aim must therefore be to confirm the currently available recommendations for various types of sport in controlled studies.

    Impaired proprioception and poor muscular stabilization in the frontal plane may lead to knee instability during functional activities, a common complaint in persons with knee osteoarthritis (KOA). Understanding these frontal plane neuromechanical properties in KOA will help elucidate the factors contributing to knee instability and aid in the development of targeted intervention strategies. The study objectives were to compare knee varus-valgus proprioception, isometric muscle strength, and active muscular contribution to stability between persons with medial KOA and healthy controls. We evaluated knee frontal plane neuromechanical parameters in 14 participants with medial KOA and 14 age- and gender-matched controls, using a joint driving device (JDD) with a customized motor and a 6-axis force sensor. Analysis of covariance with BMI as a covariate was used to test the differences in varus-valgus neuromechanical parameters between these two groups. The KOA group had impaired varus proprioception acuity (1.08 ± 0.59° vs. 0.69 ± 0.49°, p varus muscle strength (1.31 ± 0.75% vs. 1.79 ± 0.84% body weight, p varus-valgus control deficits in both the afferent input (proprioceptive acuity) and muscular effectors (muscle strength and capacity to stabilize the joint).

    2018-01-01

    People with severe psychosocial disabilities have a 20-years shorter lifespan due to chronic somatic comorbidities and the long-term consequences of the side-effects of antipsychotic drugs. They often are sedentary and show lower levels of physical activity, factors which can contribute to their shorter lifespan, because of the greater cardiovascular risk. An increasing amount of evidence, including clinical trials, pointed out that sport, physical activity and structured exercise programs improve physical and psychological wellbeing of people with psychosocial disabilities, playing also an important role against their social isolation and self-stigma. The NICE and APA guidelines include exercise and physical activity for the management of depressive symptoms. Safe and effective programs require multidisciplinary teams that should always include mental health professionals, able to recognize the psychosocial needs, the impact of symptomatology, the role of secondary effects of psychotropic medication, the effect of previous exercise history, the lack of motivation, the inexperience with effort intensity and the frustration of people with psychosocial disabilities.

    This study examined the hypothesis that when students received and/or provided either support for skill improvement or support for interpersonal relations, their overall adjustment level in extracurricular activities would be higher than for students who received and/or provided neither support. Data were analyzed from 475 junior high school students (female 175, male 300) who were taking extracurricular sports activities, out of 743 research participants. The results were as follows. Students who received support mainly for skill improvement showed a statistically equivalent adjustment level as students who received support mainly for interpersonal relations. Students who received either support showed higher adjustment levels than students who received neither. Additionally, providing support showed the same results. The exchange of different types of social support showed equivalent effects on the adjustment level as the exchange of the same type of social support. These results suggest that even though the types of social support are different for skill improvement or interpersonal relations, the exchange of support positively contributes to junior high school students' adjustment level in extracurricular activities.
