Full Text Available The research is done in order to describe student’s attitudes on volunteering in sport. The sample consists of 231 students from Serbia, average age 21,06±3,12years. They were from eight colleges and faculties. For nominal and ordinal variables, frequencies were determined. Many of examined students have volunteering experiences. The results confirm that students believe that we live in a society which his generally thought only to its own benefit; they think that volunteering can not solve the problems in society; that people do not have enough experience with volunteering and people do not have time to volunteering; volunteering is for young people; in their family and among friends, there are no volunteers; everyone could be volunteer only if that wishes; do not believe that volunteering is a waste of time and it helps in future career. The prevalent number of students, regardless of the Faculty which they belong, rarely volunteered in areas outside of sport. Results also shows that students from sport faculties have less experience in volunteering in sport than students from other faculties, but this difference is not dramatic.
Full Text Available Purpose: to investigate the level of communicative competence of sport volunteers. Material & Methods: students of Kharkov state academy of physical culture (2–4 courses who are engaged in sports volunteering.

Practitioners of martial arts have long seen a need for a precise method of measuring the power of a karate kick or a boxer's punch in training and competition. Impax sensor is a piezoelectric film less than one thousandth of an inch thick, yet extremely durable. They give out a voltage impulse when struck, the greater the force of impact, the higher the voltage. The impulse is transmitted to a compact electronics package where voltage is translated into a force-pounds reading shown on a digital display. Impax, manufactured by Impulse Technology, Inc. is used by martial arts instructors, practitioners, U.S. Olympic Committee Training Center, football blocking sleds, and boxers as well as police defensive tactics, providing a means of evaluating the performance of recruits.
Full Text Available Purpose: identification of the main structural components and content of sports volunteer activities. Material & Methods: used analysis of literature and documents, organizational analysis. Result: basic structural components of sports volunteer activity are defined. The content of sports volunteer activity is disclosed. Conclusion: sports volunteer activity includes the following structural components: subject, object, purpose, motivation, means, actions; subject is a sports volunteer, the object is a sports competition, the goal is to provide gratuitous assistance for a quality competition, the means are the special knowledge, skills, communication abilities of sports volunteers, actions should be understood as types of volunteer activities and functions that volunteers perform during the preparation and conduct of competitions. Main types of sports volunteer activity are: 1 organizational; 2 judiciary; 3 coaching; 4 legal; 5 medical. Functions that volunteers perform in the competition system are general and special. Content of the functions of sports volunteering depends on the specifics of the sports, the rank of the competition, the specifics of the competition for people with special needs.

This article analyses the conditions influencing volunteering in sports clubs. It focuses not only on individual characteristics of volunteers but also on the corresponding structural conditions of sports clubs. It proposes a model of voluntary work in sports clubs based on economic behaviour theory. The influences of both the individual and context levels on the decision to engage in voluntary work are estimated in different multilevel models. Results of these multilevel analyses indicate that volunteering is not just an outcome of individual characteristics such as lower workloads, higher income, children belonging to the sports club, longer club memberships, or a strong commitment to the club. It is also influenced by club-specific structural conditions; volunteering is more probable in rural sports clubs whereas growth-oriented goals in clubs have a destabilising effect.

Full Text Available Understanding personality characteristics of volunteers are important for their recruitment and retention in sport associations. This study compared self-concept as a personality characteristic between volunteer and non-volunteer students in sport associations. The method of this research was survey and descriptive. The statistical population consisted of volunteer and non-volunteer students in sport associations of Iran universities. Two hundred and fifty two students (120 volunteers and 132 non-volunteers from 10 universities were selected as subjects by using random clustered sampling method. Pyryt and Mandaglio Self Perceived Survey (PMSPS was used to collect the data. The content and face reliability of questionnaire was checked and confirmed. Cronbach’s alpha coefficient was used to test the reliability of the questionnaire (alfa=0.90. Independent t test and U Mann-Whitney test were used for comparison of the factors between volunteers and non-volunteers. Findings of this study indicated that there was a significant difference between volunteer and non-volunteer students in social and athletic self-concept. The mean of scientific and value factors were higher in volunteers than non-volunteers, however, they were not statistically significant. We concluded that the nature of sport (active and sport volunteering (social encourage students who have higher self-concept for volunteering. Moreover, the characteristics of sport associations can increase self-concept in sport volunteers.
Full Text Available Studies three concepts of transformational, transactional and laissez-faire leaderships as three independent and individual dimensions. This field study is descriptive and correlative. Statistical population of this study is the volunteer students in universities' sport associations of 10 regions of the country. Among 73 universities, 17 had active sport associations. Based on Morgan table, 231 students were selected as statistical sample (n=231 from which the results of 208 questionnaires were analyzed. Bass and Avolio (1995 Multifactor Leadership Questionnaire (MLQ was used to measure managers' leadership style of the universities' sport administrations. This questionnaire includes 41 questions with 5-value Lickert scale (1=never to 5=always. Choosing satisfaction from experiencing as the most important dimension of satisfaction shows volunteers' high level of satisfaction from experiences they have acquired in universities sport associations. The reason of this fact is that sport activity in the association is long term in nature. Sport association provides the students an opportunity to experience and use their experiences in their sport and work life. This study illustrates that girls are more satisfied than boys in all satisfaction dimensions (especially acquiring experience, career, commitment, and material in sport associations. Researches show that female students' satisfaction is more than male students' satisfaction and women's job satisfaction is more than men's job satisfaction. Thus, the higher degree of job satisfaction and experiencing in female students seems more justifying. Also, it's been cleared that sport students were more satisfied than other students in all satisfaction dimensions (especially acquiring experience, career, purposeful, and commitment

Currently more than 5800 hospice organizations operate in the United States. 1 Hospice organizations are required by the Centers for Medicare and Medicaid Services (CMS) to use volunteers for services provided to patients. 2 Although CMS regulates the amount of hours hospice volunteers should provide, there are currently no national requirements for objectives of training. 3 The purpose of this study was to gather information from a sample of hospices regarding volunteer coordinator background, current training for volunteers, importance of training objectives, and any comments regarding additional objectives. Representative state hospice organizations were contacted by e-mail requesting their participation and distribution of the survey throughout their member hospices. The survey asked demographical questions, along with ratings of training components based on perceived level of importance and time spent on each objective. A total of 90 surveys were received, and the response rate was undeterminable. Results showed the majority of hospices were nonprofit, had less than 100 currently trained volunteers, and maintained an average daily patient census of less than 50. Questions regarding training programs indicated that most use live lecture methods of approximately 19 hours or less in duration. Overall, responding hospice organizations agreed that all objectives surveyed were important in training volunteers. The small number of respondents to this survey makes generalization nationwide difficult, however it is a strong starting point for the development of further surveys on hospice volunteer training and achieving a standardized set of training objectives and delivery methods.

The principle of training can be reduced to a simple "dose-response" relationship. The "response" in this relationship can be measured as a change in performance or the adaptation of a physiological system. The "dose" of training, or physiological stress associated with the training load, is more difficult to measure as there is no absolute "gold standard" which can be used in the field, making it difficult to validate procedures. Attempts have been made to use heart rate as a marker of intensity during training, but the theoretical attractiveness of this method is not supported by the accuracy and the practicality of using this method during training or competition. The session RPE, based on the product of training duration and perceived intensity is more practical and can be used in a variety of sports. However, the score depends on a subjective assessment, and the intersubject comparisons may be inaccurate. The demands of different sports vary and therefore the methods of assessing training need to vary accordingly. The time has come to reach consensus on assessing training accurately in different sports. There is a precedent for this consensus approach with scientists having already done so for the assessment of physical activity, and for defining injuries in rugby, football and cricket. Standardizing these methods has resulted in the quality of research in these areas increasing exponentially.

Although the role of volunteers is at the heart of hospice care, little is known about hospice volunteer training and volunteer activity. A survey was used to assess current training programs for hospice volunteers. Hospices were invited to participate in the study from a link on the website for the Hospice Volunteer Association and Hospice Educators Affirming Life Project. Survey results revealed that the majority of volunteer work is in patient care, with most hospice agencies requiring a minimum 12-month volunteer commitment and an average 4-hour volunteer shift per week. Volunteer training is separate from staff training, is provided by paid agency staff, and costs approximately $14,303 per year. Communication and family support are considered important curriculum topics. Revisions to current volunteer training curriculum and format are suggested.

We surveyed volunteers from 8 hospices in the Delaware Valley regarding training, perceived needs, and role satisfaction. Results were consistent with previous studies: satisfaction with preservice training and with volunteering was very high; respondents reported feeling very prepared and confident about doing hospice work as a result of their volunteer training. In addition, longer volunteer preservice training was associated with higher levels of overall satisfaction with training; levels of volunteer satisfaction and fulfillment tended to be lower during the first year of volunteering; and participation in volunteer support teams was associated with finding volunteer work rewarding and with feeling a part of the hospice team. Implications for preservice training and ongoing support and education of hospice volunteers are discussed.

An optimal psychologic state for peak athletic performance is strongly documented in the sport psychology literature. A wealth of peer-reviewed studies also strongly supports the role that mental skills training (MST) plays in the development of this state. However, some disagreement exists in the sport psychology community over how best to deliver the MST tools and skills necessary for optimal sport performance. Mental training consultants and intervention researchers have recently suggested that periodization of mental training may be the next major leap forward in applied sport psychology program delivery. This new method of "training the mind" is presented and discussed.

The adaptive response to training is determined by the combination of the intensity, volume, and frequency of the training. Various periodized approaches to training are used by aquatic sports athletes to achieve performance peaks. Nutritional support to optimize training adaptations should take periodization into consideration; that is, nutrition should also be periodized to optimally support training and facilitate adaptations. Moreover, other aspects of training (e.g., overload training, tapering and detraining) should be considered when making nutrition recommendations for aquatic athletes. There is evidence, albeit not in aquatic sports, that restricting carbohydrate availability may enhance some training adaptations. More research needs to be performed, particularly in aquatic sports, to determine the optimal strategy for periodizing carbohydrate intake to optimize adaptations. Protein nutrition is an important consideration for optimal training adaptations. Factors other than the total amount of daily protein intake should be considered. For instance, the type of protein, timing and pattern of protein intake and the amount of protein ingested at any one time influence the metabolic response to protein ingestion. Body mass and composition are important for aquatic sport athletes in relation to power-to-mass and for aesthetic reasons. Protein may be particularly important for athletes desiring to maintain muscle while losing body mass. Nutritional supplements, such as b-alanine and sodium bicarbonate, may have particular usefulness for aquatic athletes' training adaptation.

The goal was better understanding of the motivational factors of volunteers in non-profit sport organizations. The roles of two factors provided by supervisors to their subordinates were examined: autonomy support, i.e., the encouragement of self-initiation and emphasis on choice rather than control, and structure, i.e., the introduction of order, definite procedures, and rules. 489 sport volunteers (289 men, 200 women; M age = 31.2 yr., SD = 7.4) were administered questionnaires assessing their perceived autonomy support, structure, and motivation. Regression analysis indicated that perceived autonomy support predicted motivation. Structure also mediated the effect of perceived autonomy support on motivation. Supervisors of sport organizations should provide adequate structure for their volunteers.

Statistical populations of this study included the whole volunteer students in sport associations of countries decimal zones universities. The sample of the study consisted of 231 volunteers who were selected by Morgan Table (n=231, which the results of 208 questionnaires were statistically analyzed. After verifying the validity of questionnaires by the experts, their reliability were calculated as (α=0.91 and α=0.88 respectively for leadership style and Satisfaction questionnaires by Cronbach's alpha coefficient in a pilot study. Data were analyzed with parametric tests at P0.05. Also, There was negative significant relationship between laissez-faire leadership style and volunteers' satisfaction (r= -0.355, sig=0.001. Furthermore, there was a significant difference between preferences of managers' leadership styles. Thus, transformational style (3.723+0.683 was in first and the transactional (3.476+0.572 and laissez-faire (2.827+0.833 styles were in next preferences. Also, from volunteer students' perspective, Satisfaction of acquiring experience, career and social were the most important dimensions, and material Satisfaction was the least important factor. According to research results, It seems that managers of Physical Education offices universities can increase the amount of volunteers' Satisfaction and provide background of their more and most effective attendance in sport association with transformational and inspiration leadership styles, appropriate incentive policies and converting sport association environment to a place in which easier accessibility to individuals' volunteer incentives becomes possible.

While the sinking of the Tenyo Maru and resultant oil spill off Washington's Olympic Peninsula in July 1991 was tragic, it fostered the birth of a cooperative effort by federal and state agencies to train volunteer responders prior to another oil spill. This effort, under the auspices of an Oregon nonprofit group known as SOLV (Stop Oregon Littering and Vandalism), is known as the SOS (SOLV Oil Spill) Steering committee. The purpose of the group is to train volunteer responders to aid federal, state, and local agencies in future oil spill cleanup activities. For the first time in the nation, governmental agencies have joined with corporations and environmental organizations in coordinating educational programs involving citizens in oil spill remediation efforts before the advent of a major spill that could affect coastal areas or inland waterways. Free classes meeting federal and state hazardous waste training criteria are offered quarterly to citizens interested in either volunteer wildlife rehabilitation or beach cleanup. The four-hour course was developed by the US Coast Guard, Oregon State Department of Environmental Quality, and Oregon OSHA. Topics covered include agency responsibilities, site safety plans, general safety, toxicology, material safety data sheets, personal protective equipment, decontamination, heat stress, helicopter safety, and wildlife safety. In addition to course materials, participants receive a certificate and identification card verifying their training. A 1-800 number, computer data base, and newsletter are used to maintain contact with graduates. So far more than 600 volunteers have been trained and are ready to assist should the need arise

Full Text Available The sport training is a process that, by means of the physical exercise, tends to reach a more or less high level according to the proposed objectives, causing a modification of the physical, motor, cognitive and affective state on the athletes with the aim to obtain competitive results. It can also be defined as the main form of putting into practice the sportsman's preparation, being the most important features the fact that it represents an organized didactic process which is characterized by the rigorous use of all teaching, education and selfeducacion process factors, as well as a methodological system of the physical exercises that constitutes the base of the sport training with the purpose of achieving the biggest effect in the development, whenever it is possible to direct the process of sport improvement fully. The personality is a concrete person in all his/her social and psychological particularities diversity; it is the subject of the social activity and of the social relationships. One of the most characteristic aspects in the human personality is his/her individuality, understanding it as a group, only in his/her gender, with psychological particularities that makes each individual different from the other ones, in relation with the character, the temperament, the peculiarities to reflect the psychic processes, the group of feelings and reasons for the activity. The understanding and the consideration of the individual particularities have a great importance in the sportsman's practical life during the training. Starting from the inadequacies detected in the trainings and competitions connected with the athletes’ preparation, assimilation and application of the received knowledge, we propose the present material about personalized training, like tool for trainers´ development in order to achieve the sportsman's more complete preparation, taking into account the contemporary training direction.

Several research programs are tackling the use of Wireless Sensor Networks (WSN) at specific fields, such as e-Health, e-Inclusion or e-Sport. This is the case of the project "Ambient Intelligence Systems Support for Athletes with Specific Profiles", which intends to assist athletes in their training. In this paper, the main developments and outcomes from this project are described. The architecture of the system comprises a WSN deployed in the training area which provides communication with athletes' mobile equipments, performs location tasks, and harvests environmental data (wind speed, temperature, etc.). Athletes are equipped with a monitoring unit which obtains data from their training (pulse, speed, etc.). Besides, a decision engine combines these real-time data together with static information about the training field, and from the athlete, to direct athletes' training to fulfill some specific goal. A prototype is presented in this work for a cross country running scenario, where the objective is to maintain the heart rate (HR) of the runner in a target range. For each track, the environmental conditions (temperature of the next track), the current athlete condition (HR), and the intrinsic difficulty of the track (slopes) influence the performance of the athlete. The decision engine, implemented by means of (m, s)-splines interpolation, estimates the future HR and selects the best track in each fork of the circuit. This method achieves a success ratio in the order of 80%. Indeed, results demonstrate that if environmental information is not take into account to derive training orders, the success ratio is reduced notably.

Team sports are increasingly popular, with millions of participants worldwide. Athletes engaged in these sports are required to repeatedly produce skilful actions and maximal or near-maximal efforts (eg, accelerations, changes in pace and direction, sprints, jumps and kicks), interspersed with brief recovery intervals (consisting of rest or low-intensity to moderate-intensity activity), over an extended period of time (1–2 h). While performance in most team sports is dominated by technical and tactical proficiencies, successful team-sport athletes must also have highly-developed, specific, physical capacities. Much effort goes into designing training programmes to improve these physical capacities, with expected benefits for team-sport performance. Recently, some team sports have introduced altitude training in the belief that it can further enhance team-sport physical performance. Until now, however, there is little published evidence showing improved team-sport performance following altitude training, despite the often considerable expense involved. In the absence of such studies, this review will identify important determinants of team-sport physical performance that may be improved by altitude training, with potential benefits for team-sport performance. These determinants can be broadly described as factors that enhance either sprint performance or the ability to recover from maximal or near-maximal efforts. There is some evidence that some of these physical capacities may be enhanced by altitude training, but further research is required to verify that these adaptations occur, that they are greater than what could be achieved by appropriate sea-level training and that they translate to improved team-sport performance.

Conclusion: These findings indicate that the mode of sport training, which results in either high cardiovascular or high motor fitness, bears no relationship to measures of general cognition in elite athletes. The present findings suggest that coaches and athletic trainers should be encouraged to monitor athletes' stress levels during training in order to maximize the beneficial effects of such training on general cognitive performance.

Today, vulnerable populations expand as the threats of homelessness and communicable diseases continue to grow. Volunteers are moved to serve in areas in which they may not be well prepared. We identify the caring needs of high-risk, vulnerable populations and the needs of volunteers; we also conceptualize, develop, implement, and evaluate a training program for volunteers who serve homeless persons and families. This training program and the imperatives that undergird it are presented as a model applicable to the training of volunteers serving high-risk, vulnerable populations.

Field-based team sport matches are composed of short, high-intensity efforts, interspersed with intervals of rest or submaximal exercise, repeated over a period of 60-120 minutes. Matches may also be played at moderate altitude where the lower oxygen partial pressure exerts a detrimental effect on performance. To enhance run-based performance, team-sport athletes use varied training strategies focusing on different aspects of team-sport physiology, including aerobic, sprint, repeated-sprint and resistance training. Interestingly, 'altitude' training (i.e. living and/or training in O(2)-reduced environments) has only been empirically employed by athletes and coaches to improve the basic characteristics of speed and endurance necessary to excel in team sports. Hypoxia, as an additional stimulus to training, is typically used by endurance athletes to enhance performance at sea level and to prepare for competition at altitude. Several approaches have evolved in the last few decades, which are known to enhance aerobic power and, thus, endurance performance. Altitude training can also promote an increased anaerobic fitness, and may enhance sprint capacity. Therefore, altitude training may confer potentially-beneficial adaptations to team-sport athletes, which have been overlooked in contemporary sport physiology research. Here, we review the current knowledge on the established benefits of altitude training on physiological systems relevant to team-sport performance, and conclude that current evidence supports implementation of altitude training modalities to enhance match physical performances at both sea level and altitude. We hope that this will guide the practice of many athletes and stimulate future research to better refine training programmes.

Sports specialization is becoming the norm in youth sports for a variety of reasons. When sports specialization occurs too early, detrimental effects may occur, both physically and psychologically. If the timing is correct and sports specialization is performed under the correct conditions, the athlete may be successful in reaching specific goals. Young athletes who train intensively, whether specialized or not, can also be at risk of adverse effects on the mind and body. The purpose of this clinical report is to assist pediatricians in counseling their young athlete patients and their parents regarding sports specialization and intensive training. This report supports the American Academy of Pediatrics clinical report "Overuse Injuries, Overtraining, and Burnout in Child and Adolescent Athletes."

To overview a framework that provides a theoretically-grounded approach to predicting the types of modified perceptual training tasks that will stimulate transfer of improved perceptual skills to sport performance environments. Modified perceptual training (MPT) collectively describes on- or off-field sports training tasks that are specifically designed to develop visual and perceptual-cognitive skill. Traditional training approaches in sport include sports vision training and perceptual-cognitive training, while recently, new technologies have enabled a broad range of additional MPT tools to become available to coaches and athletes. Short literature review and opinion article. Literature in the fields of sports vision training and perceptual-cognitive training are summarised and contrasted. A selection of emerging MPT technologies are then overviewed. This leads to the identification of three interacting factors of MPT task design that may influence the task's capacity to transfer improved training performance to actual competition: (i) the targeted perceptual function, (ii) stimulus correspondence, and (iii) response correspondence, which are assimilated with key tenets of representative learning design. These three theoretically-grounded differences are adopted to support and justify the structure of the Modified Perceptual Training Framework which sets out predictions for future research to test in order to clarify the transfer effect of MPT tools. The application of the Modified Perceptual Training Framework may assist in future testing, design and selection of beneficial training tools in sport and as such, is predicted to have significant impact in empirical and practical settings.

A prevailing theory (and practical application) is that elite performance requires early childhood skill development and training across various domains, including sport. Debate continues whether children specializing early (ie, training/competition in a single sport) have true advantage compared with those who sample various sports early and specialize in a single sport later (adolescence). Retrospective data and case studies suggest either model yields elite status depending upon the sport category (ie, situational: ball games, martial arts, fencing; quantitative: track and field, swimming, skiing; or qualitative: gymnastics, diving, figure skating). However, potential risks of early specialization include greater attrition and adverse physical/emotional health outcomes. With the advent of the IOC Youth Olympic Games, increased emphasis on global youth competition has unknown implications but also represents a potential platform for investigation. Modification of youth competition formats should be based upon multidisciplinary research on psychophysiological responses, and technical-tactical behaviors during competition. The assumption that a simple scaled-down approach of adult competitions facilitates the development of technical/tactical skills of youth athletes is not necessarily substantiated with field-based research. Relatively little evidence exists regarding the long-term effects of rigorous training and competitive schedules on children in specific sports. It is clear that more prospective studies are needed to understand the training dose that optimally develops adaptations in youth without inducing dropout, overtraining syndrome, and/or injury. Such an approach should be sport specific as well as gender based. Until such evidence exists, coaches and sport administrators will continue to rely upon their sport-specific dogma to influence programmatic development of our most vulnerable population.
Full Text Available BACKGROUND: Together with the increase of importance of sport as a social phenomenon importance of optimizing the system of sports training of talented athletes is growing. OBJECTIVES: The aim of this study was to obtain information on the activities of coaches, training process, and conditions under which they are realized in volleyball youth sports centers in the Czech Republic (SpS. METHODS: We have created a survey focused on six topical areas of sports training in volleyball. This paper deals with the analysis of areas "Coaches and their activities" and "training process". The questionnaire was sent to 18 coaches of male teams incorporated to SpS, 18 coaches responded (response rate 100%. RESULTS: We found a statistically significant relationship (rpb = 0.41; p < 0.05 between long-term performance and competences of coaches. The research shows that activity in particular SpS in most areas is consistent with current knowledge and trends in youth training. Reserves exist primarily in the number of coaches working with individual teams (in 13 cases only 1 coach and in regeneration. In some SpS a unified training strategy is missing and training process is not properly structured. CONCLUSIONS: The study allowed partial evaluation of conditions, quality and content of the training process in the SPS. The acquired knowledge can contribute to the improvement of SpS functioning.

There is emerging evidence supporting the use vision training, including light board training tools, as a concussion baseline and neuro-diagnostic tool and potentially as a supportive component to concussion prevention strategies. This paper is focused on providing detailed methods for select vision training tools and reporting normative data for comparison when vision training is a part of a sports management program. The overall program includes standard vision training methods including tachistoscope, Brock's string, and strobe glasses, as well as specialized light board training algorithms. Stereopsis is measured as a means to monitor vision training affects. In addition, quantitative results for vision training methods as well as baseline and post-testing *A and Reaction Test measures with progressive scores are reported. Collegiate athletes consistently improve after six weeks of training in their stereopsis, *A and Reaction Test scores. When vision training is initiated as a team wide exercise, the incidence of concussion decreases in players who participate in training compared to players who do not receive the vision training. Vision training produces functional and performance changes that, when monitored, can be used to assess the success of the vision training and can be initiated as part of a sports medical intervention for concussion prevention.

The question of whether altitude training can enhance subsequent sea-level performance has been well investigated over many decades. However, research on this topic has focused on athletes from individual or endurance sports, with scant number of studies on team-sport athletes. Questions that need to be answered include whether this type of training may enhance team-sport athlete performance, when success in team-sport is often more based on technical and tactical ability rather than physical capacity per se. This review will contrast and compare athletes from two sports representative of endurance (cycling) and team-sports (soccer). Specifically, we draw on the respective competition schedules, physiological capacities, activity profiles and energetics of each sport to compare the similarities between athletes from these sports and discuss the relative merits of altitude training for these athletes. The application of conventional live-high, train-high; live-high, train-low; and intermittent hypoxic training for team-sport athletes in the context of the above will be presented. When the above points are considered, we will conclude that dependent on resources and training objectives, altitude training can be seen as an attractive proposition to enhance the physical performance of team-sport athletes without the need for an obvious increase in training load.

Full Text Available Over the past years, the role of physical education and sports in youth health improvement has deteriorated, the public status of physical training for purposes of health improvement and promotion has fallen. The article outlines the results of a study of attitudes to physical education and sports among 310 senior grades in secondary schools of the town of Zhukovsky in Moscow region under the program of research into health-saving behaviours in adolescents. Along with a low sports activity most adolescents of both sexes do not do morning exercises at all. At the same time, their overall motor performance is also at a very low level. The sedentary life style becomes a dominant feature in the development of younger generation.Key words: adolescents, attitude to sports, motor performance.

Weight-training sports, including weightlifting, powerlifting, bodybuilding, strongman, Highland Games, and CrossFit, are weight-training sports that have separate divisions for males and females of a variety of ages, competitive standards, and bodyweight classes. These sports may be considered dangerous because of the heavy loads commonly used in training and competition. Our objective was to systematically review the injury epidemiology of these weight-training sports, and, where possible, gain some insight into whether this may be affected by age, sex, competitive standard, and bodyweight class. We performed an electronic search using PubMed, SPORTDiscus, CINAHL, and Embase for injury epidemiology studies involving competitive athletes in these weight-training sports. Eligible studies included peer-reviewed journal articles only, with no limit placed on date or language of publication. We assessed the risk of bias in all studies using an adaption of the musculoskeletal injury review method. Only five of the 20 eligible studies had a risk of bias score ≥75 %, meaning the risk of bias in these five studies was considered low. While 14 of the studies had sample sizes >100 participants, only four studies utilized a prospective design. Bodybuilding had the lowest injury rates (0.12-0.7 injuries per lifter per year; 0.24-1 injury per 1000 h), with strongman (4.5-6.1 injuries per 1000 h) and Highland Games (7.5 injuries per 1000 h) reporting the highest rates. The shoulder, lower back, knee, elbow, and wrist/hand were generally the most commonly injured anatomical locations; strains, tendinitis, and sprains were the most common injury type. Very few significant differences in any of the injury outcomes were observed as a function of age, sex, competitive standard, or bodyweight class. While the majority of the research we reviewed utilized retrospective designs, the weight-training sports appear to have relatively low rates of injury compared with common team

The purposes of this review are to identify the factors that contribute to the transference of strength and power training to sports performance and to provide resistance-training guidelines. Using sprinting performance as an example, exercises involving bilateral contractions of the leg muscles resulting in vertical movement, such as squats and jump squats, have minimal transfer to performance. However, plyometric training, including unilateral exercises and horizontal movement of the whole body, elicits significant increases in sprint acceleration performance, thus highlighting the importance of movement pattern and contraction velocity specificity. Relatively large gains in power output in nonspecific movements (intramuscular coordination) can be accompanied by small changes in sprint performance. Research on neural adaptations to resistance training indicates that intermuscular coordination is an important component in achieving transfer to sports skills. Although the specificity of resistance training is important, general strength training is potentially useful for the purposes of increasing body mass, decreasing the risk of soft-tissue injuries, and developing core stability. Hypertrophy and general power exercises can enhance sports performance, but optimal transfer from training also requires a specific exercise program.

A plethora of investigations examining fluid intake before, during, and after training and competition have suggested that a lack of adequate fluid intake will impair or decrease physical performance. Depending upon the type of training or competition, individuals training for prolonged endurance events should drink fluids containing carbohydrates and electrolytes during and after training or competition. Inadequate hydration will cause significant decrements in performance, increase thermal stress, reduce plasma volume, accelerate fatigue, and possibly cause injuries associated with fluid and sweat loss. However, overdrinking may cause Na+ depletion and in some cases lead to hyponatremia. Maintaining proper hydration before, during, and after training and competition will help reduce fluid loss, maintain performance, lower submaximal exercise heart rate, maintain plasma volume, and reduce heat stress, heat exhaustion, and possibly heat stroke.

Exercise is recommended as a lifestyle intervention in preventing hypertension based on epidemiological findings. However, previous intervention studies have presented mixed results. This discrepancy could be associated with shortcomings related to sample sizes or the inclusion of normotensive participants. The aim of this prospective cohort study (N = 463) was to compare the chronic effect of increasing sports training time on resting blood pressure for normotensives and hypertensives. We assessed systolic blood pressure, diastolic blood pressure, body mass index (BMI), and homeostasis model assessment for insulin resistance (HOMA-IR) for 69 untreated hypertensive patients (age 20.6 +/- 0.1 years, systolic blood pressure >140 mmHg) and 394 normotensive controls (age 20.6 +/- 0.1 years) before training and at follow-up visits at 12 months. All participants enrolled in various sports training lessons for 8 hours a week. The baseline BMI and HOMA-IR in the hypertensive group were significantly higher than those in the control group. For the normotensive control group, no significant changes in systolic and diastolic blood pressure were observed after training. However, for the hypertensives, systolic and diastolic blood pressure were significantly reduced after training by approximately 15 mmHg and approximately 4 mmHg, respectively, and HOMA-IR was reduced by approximately 25%. In conclusion, the effect of sports training to lower blood pressure was confined to the group of hypertensives, which may account for the overall minimal reduction in blood pressure observed in previous intervention studies.
When athletes consult sports outpatient or orthopedic clinics it is possible to undergo drug treatment with the medical staff having prior knowledge of that patient being an athlete. However, if athletes seek any other diagnosis and treatment as an ordinary patient, the possibility of medical staff realizing the potential for imposing a doping issue on the athlete is extremely low. As a result, if the athlete fails to provide medical staff with information regarding anti-doping regulations when receiving clinical treatment, drug treatment administered as part of medical practices could be viewed as doping, resulting in the athlete being disciplined. In order to avoid this, pharmacist should participate in training in order to be able to provide information for anti-doping purposes. It is my personal opinion that knowledge regarding anti-doping is something that should be shared by all pharmacists, as pharmacists are educated in the fields of pharmacology and pharmacokinetics during the pharmacy education process, and sports pharmacology is a part of this. However, in order for pharmacists to understand sports pharmacology, it is necessary to provide education not only on the benefits and adverse effects of pharmaceutical products, but also on the concept of banned substances. It can be considered one of the pharmacist's duties to protect athletes who purchase drugs at a pharmacy or consult medical institutions as patients. With this, I would like to propose considering the potential for introducing sports pharmacology to pharmaceutical education, and specialist pharmacist training in the sports spectrum.

The current study examined the relative efficacy of behavioral sports training, medication, and their combination in improving sports competence among youth with attention deficit/hyperactivity disorder (ADHD). Participants were 73 youth (74% male; 81% Hispanic) between the ages of 5 and 12 diagnosed with Diagnostic and Statistical Manual of Mental Disorders (4th ed.) ADHD enrolled in a Summer Treatment Program (STP). The study consisted of a 2 (medication: methylphenidate, placebo) × 2 (sports training: instruction and practice, recreational play) between-groups design and was conducted over a 3-week period during the STP. Sports training was conducted with a novel sport, badminton, to limit previous sport knowledge and to differentiate it from concurrent sports training that occurred within the STP. Objective and subjective measures of sports skills, knowledge, and behavior were collected. Results indicated that, relative to recreational play, brief sports training improved observed and counselor-rated measures of sports competence including sports skills, knowledge, game awareness, effort, frustration, and enjoyment. During sports training, medication incrementally improved children's observed rule following behavior and counselor-rated sportsmanship relative to placebo. In the absence of sports training, medication improved behavior, effort, and sport knowledge. Training in sports skills and rules produced the largest magnitude effects on sports-related outcomes. Therefore, skills training, rather than medication alone, should be used in conjunction with behavioral intervention to teach sports to youth with ADHD. It is recommended that medication be used only as an adjunct to highly structured sports skills training for youth who display high rates of negative behavior during sports activities.

Volunteers from Peter MacCallum Cancer Centre (Peter Mac) Patient Information and Support Centre (PISC) assist the Cancer Support Nurse by helping patients and families/carers find information and provide face-to-face peer support. Benefits of shared personal experiences between volunteer and patient are clearly different from professional support. Volunteers require specific skill sets and detailed preparation for this role. Volunteers completed a 3-day training programme adapted from the Cancer Council Victoria's 'Cancer Connect Telephone Peer Support Volunteer' training programme. The focus was role expectations and boundaries for peer support volunteers, debriefing, communication skills training, support services, complementary and alternative therapies and internet information. Assessment included a quiz and observation for a range of competencies. Role-play with simulated patients developed appropriate support skills. Eight volunteers participated. Pre-training questionnaires revealed all volunteers highly self-rated existing skills supporting people affected by cancer. During training, volunteers recognised these skills were inadequate. All agreed that role-play using an actor as a 'simulated patient' helped develop communication skills; however, the experience proved challenging. Post-training all reported increased knowledge of role definition and boundaries, supportive communication skills, supports available for patients and families/carers and importance of self-care. Facilitators recommended seven of the eight participants be accredited PISC Peer Support Volunteers. One volunteer was assessed unsuitable for consistently overstepping the boundaries of the peer support role and withdrew from training. Success of the programme resulted in a trained 'face-to-face peer support volunteer' group better equipped for their role. Sixteen months following training, all who completed the programme remain active volunteers in the PISC. Planned educational updates
Full Text Available Deciphering the human genome, and further development of omics technologies, have opened new opportunities in studying the molecular mechanisms underlying the sport success. According to modern concepts of functional genomics, it is believed that individual differences in the degree of development of physical and mental qualities, as well as in the susceptibility to different diseases of athletes are largely due to DNA polymorphisms. Genetic markers associated with the development and manifestation of physical qualities (speed, strength, endurance, agility, flexibility can be used in the sports selection system, to clarify sports specialization and to optimize the training process. Other molecular markers (methyl groups, transcripts, telomerase activity, telomeres, circulating DNA, metabolites, proteins, etc. in addition to predicting athletic performance, allow assessing the current functional state of the athlete, including the phenomenon of overtraining. The purpose of this review is to provide data on the use of genomic, epigenetic, transcriptomic, proteomic and metabolic methods in sports talent identification, assessing the current functional status of athletes and in the prescription of personal training and nutrition programs. Future research, including multicentre genome-wide association studies and whole-genome sequencing in large cohorts of athletes with further validation and replication, will substantially contribute to the discovery of large numbers of the causal genetic variants (mutations and DNA polymorphisms that would partly explain the heritability of athlete status and related phenotypes.

To determine the feasibility and acceptability of using trained volunteers as mealtime assistants for older hospital inpatients. Poor nutrition among hospitalised older patients is common in many countries and associated with poor outcomes. Competing time pressures on nursing staff may make it difficult to prioritise mealtime assistance especially on wards where many patients need help. Mixed methods evaluation of the introduction of trained volunteer mealtime assistants on an acute female medicine for older people ward in a teaching hospital in England. A training programme was developed for volunteers who assisted female inpatients aged 70 years and over on weekday lunchtimes. The feasibility of using volunteers was determined by the proportion recruited, trained, and their activity and retention over one year. The acceptability of the training and of the volunteers' role was obtained through interviews and focus groups with 12 volunteers, nine patients and 17 nursing staff. Fifty-nine potential volunteers were identified: 38 attended a training session, of whom 29 delivered mealtime assistance, including feeding, to 3911 (76%) ward patients during the year (mean duration of assistance 5·5 months). The volunteers were positive about the practical aspects of training and ongoing support provided. They were highly valued by patients and ward staff and have continued to volunteer. Volunteers can be recruited and trained to help acutely unwell older female inpatients at mealtimes, including feeding. This assistance is sustainable and is valued. This paper describes a successful method for recruitment, training and retention of volunteer mealtime assistants. It includes a profile of those volunteers who provided the most assistance, details of the training programme and role of the volunteers and could be replicated by nursing staff in other healthcare units. © 2014 John Wiley & Sons Ltd.

There is growing interest among emergency physicians to seek additional training in Sports Medicine (SM) and to add it to their clinical practice. This presents unique training and practice management issues. The majority of Primary Care SM fellowship programs list that they will accept emergency physicians, and approximately one-third have already had an emergency physician as an SM fellow. The objective of this article is to provide an overview of the key elements for emergency physicians to consider as they pursue SM career goals. Training needs such as continuity of care as it pertains to the athlete, SM skills development, and practice management are reviewed. Practice challenges such as malpractice insurance and billing issues are discussed. Examples of several practice models are presented. Evolving trends in SM practice and training opportunities for emergency physicians are discussed as well. Sports Medicine is a viable career option for emergency physicians and may complement their skills set in the management of acute injuries. Practice and training opportunities will continue to evolve as this pathway into the practice of SM gains further recognition. Copyright © 2013 Elsevier Inc. All rights reserved.

This research project examined the effects of a training program that focused on helping youth volunteers create a learner-centered interaction at an Aquarium. This study explored whether this learner centered training resulted in an increased ability to identify learner-centered engagement as well as reported changes in practice. Most research on training programs and professional development, that introduces learner-centered strategies examines adult teachers working in formal environments. This study examined youth volunteer staff in an informal science institution that participated in a weekly one-hour training for four weeks during their eight week long summer volunteer program. The data showed that some of topics introduced in the learner centered training, such as the importance of visitors' prior knowledge and the use of objects, were identified more often as good practice after the training. In addition, participants seemed to hold on to some of their original perceptions of good practices, such as providing positive reinforcement and modifying their physical posture to make the visitors feel comfortable. The investigation also revealed that conversation patterns changed in some participants' practice as a result of the training.

The eccentric utilization ratio (EUR), which is the ratio of countermovement jump (CMJ) to static jump (SJ) performance, has been suggested as a useful indicator of power performance in athletes. The purpose of the study was to compare the EUR of athletes from a variety of different sports and during different phases of training. A total of 142 athletes from rugby union, Australian Rules Football, soccer, softball, and field hockey were tested. Subjects performed both CMJ and SJ on a force plate integrated with a position transducer. The EUR was measured as the ratio of CMJ to SJ for jump height and peak power. The rugby union, Australian Rules Football, and hockey athletes were tested during off-season and preseason to provide EUR data during different phases of training. For men, EUR for soccer, Australian Rules Football, and rugby was greater than softball (effect size range, 0.83-0.92). For women, EUR for soccer was greater than field hockey and softball (0.86- 1.0). There was a significant difference between the jump height and peak power method for the Australian Rules Football, rugby, and field hockey tests conducted preseason (p sports such as soccer, rugby union, and Australian Rules Football appear to have higher EUR values, which reflects the greater reliance on stretch shortening activities in these sports. It does appear that EUR can be used to track changes in training with the values significantly increasing from off-season to preseason. The EUR provides the practitioner with information about the performance of athletes and appears to be sensitive to changes in the type of training being undertaken.

The overall goal of the present study was to illustrate the potential of artificial intelligence (AI) techniques in sports on the example of weight training. The research focused in particular on the implementation of pattern recognition methods for the evaluation of performed exercises on training machines. The data acquisition was carried out using way and cable force sensors attached to various weight machines, thereby enabling the measurement of essential displacement and force determinants during training. On the basis of the gathered data, it was consequently possible to deduce other significant characteristics like time periods or movement velocities. These parameters were applied for the development of intelligent methods adapted from conventional machine learning concepts, allowing an automatic assessment of the exercise technique and providing individuals with appropriate feedback. In practice, the implementation of such techniques could be crucial for the investigation of the quality of the execution, the assistance of athletes but also coaches, the training optimization and for prevention purposes. For the current study, the data was based on measurements from 15 rather inexperienced participants, performing 3-5 sets of 10-12 repetitions on a leg press machine. The initially preprocessed data was used for the extraction of significant features, on which supervised modeling methods were applied. Professional trainers were involved in the assessment and classification processes by analyzing the video recorded executions. The so far obtained modeling results showed good performance and prediction outcomes, indicating the feasibility and potency of AI techniques in assessing performances on weight training equipment automatically and providing sportsmen with prompt advice. Key pointsArtificial intelligence is a promising field for sport-related analysis.Implementations integrating pattern recognition techniques enable the automatic evaluation of data

Predictive Evaluation (PE) uses a four-step process to predict results then designs and evaluates a training intervention accordingly. In 2012, the Sustainable Management Development Program (SMDP) at the Centers for Disease Control and Prevention used PE to train Stop Transmission of Polio (STOP) program volunteers. Stakeholders defined specific beliefs and practices that volunteers should demonstrate. These predictions and adult learning practices were used to design a curriculum to train four cohorts. At the end of each workshop, volunteers completed a beliefs survey and wrote goals for intended actions. The goals were analyzed for acceptability based on four PE criteria. The percentage of acceptable goals and the beliefs survey results were used to define the quality of the workshop. A postassignment adoption evaluation was conducted for two cohorts, using an online survey and telephone or in-person structured interviews. The results were compared with the end of workshop findings. The percentage of acceptable goals across the four cohorts ranged from 49% to 85%. In the adoption evaluation of two cohorts, 88% and 94% of respondents reported achieving or making significant progress toward their goal. A comparison of beliefs survey responses across the four cohorts indicated consistencies in beliefs that aligned with stakeholders' predictions. Goal statements that participants write at the end of a workshop provide data to evaluate training quality. Beliefs surveys surface attitudes that could help or hinder workplace performance. The PE approach provides an innovative framework for health worker training and evaluation that emphasizes performance.
Traditionally, balance training has been used as part of the rehabilitation programme for ankle injuries. More recently, balance training has been adopted to try and prevent injuries to the ankle and knee joints during sport. The purpose of this review is to synthesise current knowledge in the area of balance ability, training and injury risk, highlight the findings and identify any future research needs. A number of studies have found that poor balance ability is significantly related to an increased risk of ankle injuries in different activities. This relationship appears to be more common in males than females. Multifaceted intervention studies that have included balance training along with jumping, landing and agility exercises have resulted in a significant decrease in ankle or knee injuries in team handball, volleyball and recreational athletes. It is unknown which component of the multifaceted intervention was most effective and whether the effects are additive. As a single intervention, balance training has been shown to significantly reduce the recurrence of ankle ligament injuries in soccer, volleyball and recreational athletes; however, it has not been clearly shown to reduce ankle injuries in athletes without a prior ankle injury. Balance training on its own has also been shown to significantly reduce anterior cruciate ligament injuries in male soccer players. Surprisingly, it was also found to be significantly associated with an increased risk of major knee injuries in female soccer players and overuse knee injuries in male and female volleyball players. The studies with the contrasting findings differed in aspects of their balance training programmes. It would appear that balance training, as a single intervention, is not as effective as when it is part of a multifaceted intervention. Research is required to determine the relative contribution of balance training to a multifaceted intervention so as to generate an effective and efficient preventative

The aim of this study was to carry out a comparative study of water balance and water protein composition of the blood during exposure to acute (abrupt restriction of motor activity) and ordinary rigorous bed rest of 7 days. The studies were performed on 30 long distance runners aged 22-25 years old who had a VO 2 max of 66 ml kg -1·min -1 on the average. The volunteers were divided into three equal groups: the volunteers in the 1st group were under a normal ambulatory life conditions (control subjects), the volunteers of the 2nd group subjected to an acute bed rest (abrupt restriction of motor activity) regime (acute bed rested subjects) and the volunteers of the 3rd group were submitted to ordinary and rigorous bed rest (rigorous bed rested subjects). All volunteers were on an average of 13.8 km/day before taking part in this investigation. The 2nd and 3rd groups of volunteers were kept under a rigorous bed rest regime for 7 days. During the prebed rest period and actual bed rest period plasma volume (PV), total protein and protein fractions (albumins and globulins) and hematocrit were measured. Exposure to acute bed rest conditions induced a significant increase in hematocrit, hemoglobin concentration, protein fractions and marked decrease in (PV) and water balance which were significantly more pronounced than during exposure to ordinary rigorous bed rest. It was concluded that exposure to acute bed rest conditions induces significantly greater changes in water balance and water-protein concentration of the blood of endurance trained volunteers than exposure to ordinary rigorous bed rest conditions.
Full Text Available The paper substantiates the design of the training process of athletes in team sports during an annual training cycle on the basis of model training tasks. The model training tasks are developed along with micro-and mesocycles, periods, and annual cycle for preparation of elite female volleyball players. The ratio of the training means and various types of training loads in the periods of macrocycle were determined. Introduction of model training tasks into the training process in team sports allows to efficiently plan and optimize the preparation of athletes, as well as to implement the principle of individualization in the development of a coherent team.

The increasing understanding of the genetic influences in sport has prompted an association study between the athletic performances and the polymorphisms of the angiotensin-converting enzyme (ACE), the α-actinin-3 (ACTN3), and the vitamin D receptor genes. The details of these gene polymorphisms can provide useful information to improve and plan new modern training programs for elite athletes. Eighty Italian male high level gymnasts were trained and tested for gymnastic-specific exercises and tested in all the men's artistic gymnastic apparatus (floor, pommel horse, rings, vault, parallel bars, and horizontal bar), and then genotyped. The training parameters of volume, intensity, and density of each gymnast were periodically measured during the season in each apparatus from the tests performed, and the seasonal average values were calculated. Gene polymorphisms were determined by polymerase chain reaction restriction fragment length polymorphism assay and studied in association with the performance results. The performances of ACE II gymnasts were significantly lower than that of the ACE ID/DD gymnasts in the apparatus expressing power features, confirming the predisposition of these athletes toward power-oriented sport. Gymnasts with ACTN3 RR/RX genotypes did not show a predisposition to the power-oriented apparatus, having worse performances compared with that of the ACTN3 XX gymnasts. Similarly, gymnasts with ACE II + ACTN3 RR/RX combined genotypes showed lower performances in comparison with that of the other gymnasts. Vitamin D receptor polymorphisms showed no significant association with the athletic performances. Because ACE insertion/deletion (I/D) and ACTN3 R577X polymorphisms heavily affect the physical performance of elite male gymnasts, the Italian Gymnastic Federation trainers have started to customize the current high-level training programs.

Agility is an important characteristic of team sports athletes. There is a growing interest in the factors that influence agility performance as well as appropriate testing protocols and training strategies to assess and improve this quality. The objective of this systematic review was to (1) evaluate the reliability and validity of agility tests in team sports, (2) detail factors that may influence agility performance, and (3) identify the effects of different interventions on agility performance. The review was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We conducted a search of PubMed, Google Scholar, Science Direct, and SPORTDiscus databases. We assessed the methodological quality of intervention studies using a customized checklist of assessment criteria. Intraclass correlation coefficient values were 0.80-0.91, 0.10-0.81, and 0.81-0.99 for test time using light, video, and human stimuli. A low-level reliability was reported for youth athletes using the video stimulus (0.10-0.30). Higher-level participants were shown to be, on average, 7.5% faster than their lower level counterparts. Reaction time and accuracy, foot placement, and in-line lunge movement have been shown to be related to agility performance. The contribution of strength remains unclear. Efficacy of interventions on agility performance ranged from 1% (vibration training) to 7.5% (small-sided games training). Agility tests generally offer good reliability, although this may be compromised in younger participants responding to various scenarios. A human and/or video stimulus seems the most appropriate method to discriminate between standard of playing ability. Decision-making and perceptual factors are often propositioned as discriminant factors; however, the underlying mechanisms are relatively unknown. Research has focused predominantly on the physical element of agility. Small-sided games and video training may offer effective

Points of dispensing (PODs) are deployed for medical countermeasure mass dispensing. However, infection prevention and vaccine administration pre-event training offered and just-in-time (JIT) education planned for POD workers have not been assessed. Disaster planners were sent an online questionnaire in 2013. McNemar tests compared training offered to staff versus volunteers and pre-event training versus JIT training. In total, 301 disaster planners participated. The most frequent pre-event training included hand hygiene (59.1% and 28.0%) and personal protective equipment (PPE) selection (52.1% and 24.1%) for staff and volunteers, respectively. Few provided pre-event training on the cold chain technique (14.8% and 5.1%) or smallpox vaccine administration (4.7% and 2.3%) for staff or volunteers. For all topics except smallpox vaccine administration, more staff than volunteers received pre-event training (P training includes hand hygiene (79.8% and 73.5%) and PPE selection (79.4% and 70.0%) to staff and volunteers. For all topics, more JIT education is planned for staff than volunteers (P training is planned than has been given pre-event for all topics (P training is needed on infection prevention and vaccine administration to ensure safe and successful POD deployment.

Disadvantaged childbearing women experience barriers to accessing health and social care services and face greater risk of adverse medical, social and emotional outcomes. Support from doulas (trained lay women) has been identified as a way to improve outcomes; however, in the UK doula support is usually paid-for privately by the individual, limiting access among disadvantaged groups. As part of an independent multi-site evaluation of a volunteer doula service, this study examined women's experiences of one-to-one support from a trained volunteer doula during pregnancy, labour and the post-natal period among women living in five low-income communities in England. A mixed methods multi-site evaluation was conducted with women (total n = 137) who received the service before December 2012, using a combination of questionnaires (n = 136), and individual or group interviews (n = 12). Topics explored with women included the timing and nature of support, its impact, the relationship with the doula and negative experiences. Most women valued volunteer support, describing positive impacts for emotional health and well-being, and their relationships with their partners. Such impacts did not depend upon the volunteer's presence during labour and birth. Indeed, only half (75/137; 54.7%) had a doula attend their birth. Many experienced volunteer support as a friendship, distinct from the relationships offered by healthcare professionals and family. This led to potential feelings of loss in these often isolated women when the relationship ended. Volunteer doula support that supplements routine maternity services is potentially beneficial for disadvantaged women in the UK even when it does not involve birth support. However, the distress experienced by some women at the conclusion of their relationship with their volunteer doula may compromise the service's impact. Greater consideration is needed for managing the ending of a one-to-one relationship with a volunteer

Winter sports events routinely take place at low to moderate altitudes, and nearly all Winter Olympic Games have had at least one venue at an altitude >1000 m. The acute and chronic effects of altitude can have a substantial effect on performance outcomes. Acutely, the decline in oxygen delivery to working muscle decreases maximal oxygen uptake, negatively affecting performance in endurance events, such as cross-country skiing and biathlon. The reduction in air resistance at altitude can dramatically affect sports involving high velocities and technical skill components, such as ski jumping, speed skating, figure skating and ice hockey. Dissociation between velocity and sensations usually associated with work intensity (ventilation, metabolic signals in skeletal muscle and heart rate) may impair pacing strategy and make it difficult to determine optimal race pace. For competitions taking place at altitude, a number of strategies may be useful, depending on the altitude of residence of the athlete and ultimate competition altitude, as follows. First, allow extra time and practice (how much is yet undetermined) for athletes to adjust to the changes in projectile motion; hockey, shooting, figure skating and ski jumping may be particularly affected. These considerations apply equally in the reverse direction; that is, for athletes practising at altitude but competing at sea level. Second, allow time for acclimatization for endurance sports: 3-5 days if possible, especially for low altitude (500-2000 m); 1-2 weeks for moderate altitude (2000-3000 m); and at least 2 weeks if possible for high altitude (>3000 m). Third, increase exercise-recovery ratios as much as possible, with 1:3 ratio probably optimal, and consider more frequent substitutions for sports where this is allowed, such as ice hockey. Fourth, consider the use of supplemental O(2) on the sideline (ice hockey) or in between heats (skating and Alpine skiing) to facilitate recovery. For competitions at sea

Adequate hydration status in the sport is essential for good health, yet the relationship between hydration, proteinuria and sports is little studied. To analyze the influence of an isotonic sports drink as rehydration strategy on the hydration status and proteinuria after karate training. Ten athletes participated in this study. In the first session of standard training, called observation training session (STO), the athletes hydrated themselves according to their habits, and in the second session of standard training, called nutritional intervention training session (STIN), an ideal practice of hydration protocol was followed, using an isotonic sports drink as a rehydration liquid during the training. The hydration status was verified by monitoring the body weight before and after training, the urine specific gravity pre-and post-training and the urine volume post-training. To observe the influence of practice of hydration on the renal function post exercise proteinuria was measured. We observed a statistically significant difference in urine density between the samples pre- and post-exercise only on STIN (p = 0.047). When we compare the sessions, there was a lower variation in body weight (p = 0.011) and higher urinary volume (p training. In STO, there was a higher percentage of athletes who showed proteinuria (70%) compared to the STIN (50%) in the urine sample after training. The use of isotonic sports drink as practice of hydration by karate athletes promoted rehydration during one session of training and reduce post-training proteinuria.

Advancements in wearable and ubiquitous computing technologies have radically increased the possibilities for designing full-body human-computer interactions. Among this multitude of new bodily interaction possibilities are sports training technologies and bodily games. In terms of sports training...... activity as a control mechanism or the core game mechanic. While sports training technologies and bodily games build upon similar technologies and emanate from sports, they do not share focus. One focuses on measuring, monitoring and skill acquisition, while the other focuses on motivation, engagement...... and enjoyment. Thus, despite being two coexisting research areas, they do not extend or contribute to one another per se. However, bridging this gap by combining skill acquisition knowledge from sports training technologies with motivational game mechanics from bodily games holds great potential for designing...

In Spain there are around 25,000 cardiac arrests, many of them in the presence of non-medical personnel. In less than 25% of the cardio-respiratory arrests witnessed, witnesses began cardiopulmonary resuscitation. Soccer is a contact sport with multiple physical characteristics and requirements which pushes your body to the limit, thus leading to a higher chance of developing multiple lesions, including cardio-respiratory arrest. Therefore, our goal was to know the actual situation on training in basic life support in soccer. A literature review was performed on different databases both national (IME, CUIDEN, ENCUENTR@, ENFERMERÍA AL DÍA, ISOC) and international (PUBMED, SCOPUS, CINAHL), with different MESH descriptors related to the topic. A total of 395 references were identified. 17 studies were selected; 8 of them had like main theme cardiopulmonary resuscitation and the remaining 9 spoke on the use of semi-automatic defibrillators. There is a lack of research on this topic in soccer. This strikes our attention because in this area there could be situations requiring immediate rescue action. Therefore, we emphasize the importance of early cardio-respiratory resuscitation because training in basic life support and semi-automatic defibrillators in soccer are fundamental.

With the evolving boundaries of sports science and greater understanding of the driving factors in the human performance physiology, one of the limiting factors has now become the technology. The growing scientific interest on the practical application of hypoxic training for intermittent activities such as team and racket sports legitimises the development of innovative technologies serving athletes in a sport-specific setting. Description of a new mobile inflatable simulated hypoxic equipment. The system comprises two inflatable units-that is, a tunnel and a rectangular design, each with a 215 m(3) volume and a hypoxic trailer generating over 3000 Lpm of hypoxic air with FiO₂ between 0.21 and 0.10 (a simulated altitude up to 5100 m). The inflatable units offer a 45 m running lane (width=1.8 m and height=2.5 m) as well as a 8 m × 10 m dome tent. FiO₂ is stable within a range of 0.1% in normal conditions inside the tunnel. The air supplied is very dry-typically 10-15% relative humidity. This mobile inflatable simulated hypoxic equipment is a promising technological advance within sport sciences. It offers an opportunity for team-sport players to train under hypoxic conditions, both for repeating sprints (tunnel configuration) or small-side games (rectangular configuration).

Team sports are increasingly popular, with millions of participants worldwide. Athletes engaged in these sports are required to repeatedly produce skilful actions and maximal or near-maximal efforts (eg, accelerations, changes in pace and direction, sprints, jumps and kicks), interspersed with brief recovery intervals (consisting of rest or low-intensity to moderate-intensity activity), over an extended period of time (1–2 h). While performance in most team sports is dominated by technical an...

To determine whether medical students and faculty perceive differences in the effectiveness of interactions with real patients versus simulated patients (SPs) in communication skills training. In 2008, the authors recruited volunteer outpatients (VOs) from the Johns Hopkins University School of Medicine internal medicine practice to participate in communication skills training for all first-year medical students. VOs and SPs were assigned to clinic rooms in the simulation center. Each group of five students and its preceptor rotated through randomly assigned rooms on two of four session days; on both days, each student interviewed one patient for 15 minutes, focusing on past medical and family history or social history. Patients used their own histories, not scripts; students were not blinded to patient type. Students and faculty then rated aspects of the interview experience. Generalized linear latent and mixed-models analysis was used to compare ratings of communication skills training with VOs versus SPs. All 121 first-year students participated in 242 interviews, resulting in 237 usable questionnaires (98%). They rated their experiences with VOs significantly higher than those with SPs on comfort, friendliness, amount of learning, opportunity to build relationships, and overall meeting of communication skills training needs. The 24 faculty preceptors' ratings of the 242 interactions did not differ significantly between VOs and SPs. Use of VOs was well received by students and faculty for teaching communication skills. Expanding and further studying VOs' participation will allow greater understanding of their potential role in communication skills training of preclinical medical students.

This study examined General Practitioner's (GP) knowledge, practice and training requirements in relation to doping in sport in Ireland. All 2083 GPs on the Irish College of General Practitioners (ICGP) register received a postal questionnaire, yielding a 37% response rate (N=771, 63% male, average age 46.2 +/- 9SD, range 28-74 years). Results revealed that 14% (112) deemed their knowledge of doping agents to be good or very good, 12% (94) had completed specific training modules in doping or sport, and 24% (183) were connected with a specific sport as a team doctor/advisor. Over one in four (28%: 217) had been consulted for advice on doping in Sport, 33% (256) possessed the current list of prohibited substances, and 25% (190) knew of the Irish Sports Council's drug-testing procedures. The current initiatives to discourage doping in sport were felt to be ineffective, and although 92% (716) indicated that GPs had a role to play in the prevention of doping in sport, only 9% (66) felt adequately trained for such a role. There was overwhelming support for further training among GPs, although the most appropriate method of providing training is complex and requires strategic planning.

Identifying and quantitatively analysing social determinants affecting disabled teenagers' inclusion/exclusion in high-performance sports. This was a descriptive cross-sectional study involving 19 12- to 19-year-old athletes suffering physical and sensory disability and 17 staff from the District Institute of Recreation and Sport. Likert-type rating scales were used, based on four analysis categories, i.e. social structure, socio-economic, educational and living condition determinants. Social inequity pervades the national paralympic sports' system. This is because 74 % of individuals only become recognised as sportspeople when they have obtained meritorious results in set competition without appropriate conditions having been previously provided by such paralympic sports institution to enable them to overcome structural and intermediate barriers. The social structure imposed on district-based paralympic sport stigmatises individuals regarding their individual abilities, affects their empowerment and freedom due to the discrimination experienced by disabled teenagers regarding their competitive achievements.

The US Department of Homeland Security identified college sport venues as terrorist targets due to the potential for mass casualties and catastrophic social and economic impact. Therefore, it is critical for college sport safety and security personnel to implement effective risk management practices. However, deficiencies have been identified in the level of preparedness of college sport event security personnel related to risk management training and effective emergency response capabilities. To address the industry need, the National Center for Spectator Sports Safety and Security designed, developed, and evaluated a national sport event risk management training program for National Collegiate Athletic Association command groups. The purpose of this article was to provide an overview of the design, development, and evaluation process.

Full Text Available The bodyboard is a surfing discipline whose growth has been considerably since the 60s, so it is considered one of the fastest growing aquatic sport in the world. Despite this, scientific research of this discipline has been reflected poorly compared to other sports. As in any other sport, the bodyboarder requires of specific physical and physiological conditions to help it to practice the sport effectively as it does not follow a specific training or develop conditioning programs. Therefore, this article comes up with the idea of providing a basis for determining the most appropriate training based on study objectives and bodyboard actions to improve physical, technical and psychological condition of the bodyboarders based on the particularities of their own sport and the athlete, taking into account scientific studies in the field at hand: the Bodyboard.

Previous research has indicated that training in the martial arts leads to a reduction in levels of hostility. However, such research has only compared hostility within martial arts groups. The present research compares two martial arts groups and two other sporting groups on levels of assaultive, verbal and indirect hostility. Moderated multiple regression analyses revealed a significant interaction between length of training in the respondent's stated sport and whether that sport was a martial art in predicting assaultive and verbal hostility. The form of the interaction suggests that participation in the martial arts is associated, over time, with decreased feelings of assaultive and verbal hostility. PMID:1422642

Full Text Available This study aimed to analyze the effects of power training using traditional vertical resistance exercises versus direction specific horizontal inertial flywheel training on performance in common sport-related tasks. Twenty-three healthy and physically active males (age: 22.29 ± 2.45 years volunteered to participate in this study. Participants were allocated into either the traditional training (TT group where the half squat exercise on a smith machine was applied or the horizontal flywheel training (HFT group performing the front step exercise with an inertial flywheel. Training volume and intensity were matched between groups by repetitions (5-8 sets with 8 repetitions and relative intensity (the load that maximized power (Pmax over the period of six weeks. Speed (10 m and 20 m, countermovement jump height (CMJH, 20 m change of direction ability (COD and strength during a maximal voluntary isometric contraction (MVIC were assessed before and after the training program. The differences between groups and by time were assessed using a two-way analysis of variance with repeated measures, followed by paired t-tests. A significant group by time interaction (p=0.004 was found in the TT group demonstrating a significantly higher CMJH. Within-group analysis revealed statistically significant improvements in a 10 m sprint (TT: −0.17 0.27 s vs. HFT: −0.11 0.10 s, CMJH (TT: 4.92 2.58 cm vs. HFT: 1.55 2.44 cm and MVIC (TT: 62.87 79.71 N vs. HFT: 106.56 121.63 N in both groups (p < 0.05. However, significant differences only occurred in the 20 m sprint time in the TT group (−0.04 0.12 s; p = 0.04. In conclusion, the results suggest that TT at the maximal peak power load is more effective than HFT for counter movement jump height while both TT and HFT elicited significant improvements in 10 m sprint performance while only TT significantly improved 20 m sprint performance.

Elite sporting performance results from the combination of innumerable factors, which interact with one another in a poorly understood but complex manner to mould a talented athlete into a champion. Within the field of sports science, elite performance is understood to be the result of both training and genetic factors. However, the extent to which champions are born or made is a question that remains one of considerable interest, since it has implications for talent identification and management, as well as for how sporting federations allocate scarce resources towards the optimisation of high-performance programmes. The present review describes the contributions made by deliberate practice and genetic factors to the attainment of a high level of sporting performance. The authors conclude that although deliberate training and other environmental factors are critical for elite performance, they cannot by themselves produce an elite athlete. Rather, individual performance thresholds are determined by our genetic make-up, and training can be defined as the process by which genetic potential is realised. Although the specific details are currently unknown, the current scientific literature clearly indicates that both nurture and nature are involved in determining elite athletic performance. In conclusion, elite sporting performance is the result of the interaction between genetic and training factors, with the result that both talent identification and management systems to facilitate optimal training are crucial to sporting success.

Full Text Available The primary purpose of this study was to explore the influences of training on specific quality of work outcomes of job satisfaction, pay satisfaction, and intentions to leave within high school sports officials. Evidence suggests that there is a shortage of high school officials in all categories of high school sport. Via a web-based survey, we explored the effects of training on the individual outcomes under study. Results indicated that the level of training had a significant effect on job satisfaction, pay satisfaction, and turnover intentions. Analyses indicated that officials with less training had higher turnover intentions and lower job satisfaction than officials who had more training. Conversely, officials who engaged numerous training hours had lower pay satisfaction. This exploratory study supports the importance of training high school officials but, more importantly, provides an initial assessment on the reverse effects of training on pay satisfaction.
Full Text Available Abstract Introduction: Adequate hydration status in the sport is essential for good health, yet the relationship between hydration, proteinuria and sports is little studied. Objective: To analyze the influence of an isotonic sports drink as rehydration strategy on the hydration status and proteinuria after karate training. Methods: Ten athletes participated in this study. In the first session of standard training, called observation training session (STO, the athletes hydrated themselves according to their habits, and in the second session of standard training, called nutritional intervention training session (STIN, an ideal practice of hydration protocol was followed, using an isotonic sports drink as a rehydration liquid during the training. The hydration status was verified by monitoring the body weight before and after training, the urine specific gravity pre-and post-training and the urine volume post-training. To observe the influence of practice of hydration on the renal function post exercise proteinuria was measured. Results: We observed a statistically significant difference in urine density between the samples pre- and post-exercise only on STIN (p = 0.047. When we compare the sessions, there was a lower variation in body weight (p = 0.011 and higher urinary volume (p < 0.001, on nutritional intervention training. In STO, there was a higher percentage of athletes who showed proteinuria (70% compared to the STIN (50% in the urine sample after training. Conclusion: The use of isotonic sports drink as practice of hydration by karate athletes promoted rehydration during one session of training and reduce post-training proteinuria.
Full Text Available Introduction: Over the past years, a few review papers about possibilities of using motion analysis systems in sport were published, but there are no articles that discuss this problem in the field of combat sports and martial arts. Aim: This study presents the diversity of contemporary motion analysis systems both, those that are used in scientific research, as well as those that can be applied in daily work of coaches and athletes in combat sports and martial arts. An additional aim is the indication of example applications in scientific research and range of applications in optimizing the training process. It presents a brief description of each type of systems that are currently used in sport, specific examples of systems and the main advantages and disadvantages of using them. The presentation and discussion takes place in the following sections: motion analysis utility for combat sports and martial arts, systems using digital video and systems using markers, sensors or transmitters. Conclusions: Not all types of motion analysis systems used in sport are suitable for combat sports and martial arts. Scientific studies conducted so far showed the usefulness of video-based, optical and electromechanical systems. The use of research results made with complex motion analysis systems, or made with simple systems, local application and immediate visualization is important for the preparation of training and its optimization. It may lead to technical and tactical improvement in athletes as well as the prevention of injuries in combat sports and martial arts.

Anterior cruciate ligament reconstruction (ACLR) is standard practice for athletes that wish to return to high-level activities; however functional outcomes after ACLR are poor. Quadriceps strength weakness, abnormal movement patterns and below normal knee function is reported in the months and years after ACLR. Second ACL injuries are common with even worse outcomes than primary ACLR. Modifiable limb-to-limb asymmetries have been identified in individuals who re-injure after primary ACLR, suggesting a neuromuscular training program is needed to improve post-operative outcomes. Pre-operative perturbation training, a neuromuscular training program, has been successful at improving limb symmetry prior to surgery, though benefits are not lasting after surgery. Implementing perturbation training after surgery may be successful in addressing post-operative deficits that contribute to poor functional outcomes and second ACL injury risk. 80 athletes that have undergone a unilateral ACLR and wish to return to level 1 or 2 activities will be recruited for this study and randomized to one of two treatment groups. A standard care group will receive prevention exercises, quadriceps strengthening and agility exercises, while the perturbation group will receive the same exercise program with the addition of perturbation training. The primary outcomes measures will include gait biomechanics, clinical and functional measures, and knee joint loading. Return to sport rates, return to pre-injury level of activity rates, and second injury rates will be secondary measures. The results of this ACL-Specialized Post-Operative Return To Sports (ACL-SPORTS) Training program will help clinicians to better determine an effective post-operative treatment program that will improve modifiable impairments that influence outcomes after ACLR.

Performance in most sports is determined by the athlete's technical, tactical, physiological and psychological/social characteristics. In the present article, the physical aspect will be evaluated with a focus on what limits performance, and how training can be conducted to improve performance. Specifically how intensified training, i.e., increasing the amount of aerobic high-intensity and speed endurance training, affects physiological adaptations and performance of trained subjects. Periods of speed endurance training do improve performance in events lasting 30 s-4 min, and when combined with aerobic high-intensity sessions, also performance during longer events. Athletes in team sports involving intense exercise actions and endurance aspects, such as soccer and basketball, can also benefit from intensified training. Speed endurance training does reduce energy expenditure and increase expression of muscle Na(+), K(+) pump α subunits, which may preserve muscle cell excitability and delay fatigue development during intense exercise. When various types of training are conducted in the same period (concurrent training), as done in a number of sports, one type of training may blunt the effect of other types of training. It is not, however, clear how various training modalities are affecting each other, and this issue should be addressed in future studies. © 2015 John Wiley & Sons A/S.

The aim of this study was to investigate whether a sports vision training program improves the visual performance of youth male field hockey players, ages 12 to 16 years, after an intervention of six weeks compared to a control group with no specific sports vision training. The choice reaction time task at the D2 board (Learning Task I), the functional field of view task (Learning Task II) and the multiple object tracking (MOT) task (Transfer Task) were assessed before and after the intervention and again six weeks after the second test. Analyzes showed significant differences between the two groups for the choice reaction time task at the D2 board and the functional field of view task, with significant improvements for the intervention group and none for the control group. For the transfer task, we could not find statistically significant improvements for either group. The results of this study are discussed in terms of theoretical and practical implications.

Approximately 90% of current orthopaedic graduates are engaging in fellowship training, with sports medicine being the most commonly chosen specialty. The purpose of this study was to evaluate the impact of fellowship training on clinical decision-making by fellowship-trained sports medicine surgeons. A survey was designed to assess the importance of fellowship on common clinical decisions made in the nonoperative and surgical treatment of knee, shoulder, and elbow disorders. The survey also included questions for the respondents on their comfort level with a variety of routine and complex surgical procedures. The survey was sent to alumni of 113 orthopaedic sports medicine programs across the United States. Completed surveys were returned by 310 surgeons who had been in practice for an average of 9.0 years. They represented alumni of twenty-nine orthopaedic sports medicine fellowship programs across sixteen states. Fellowship was considered very important for surgical decision-making in the knee and shoulder. For nonoperative treatment, fellowship had a greater impact on shoulder disorders than on knee or elbow disorders. Fellowship was significantly more important than residency (p sports surgeons should consider seeking additional training in the treatment of multi-ligamentous knee injuries, posterior cruciate ligament injuries, shoulder instability with bone loss, and elbow disorders. The current findings were limited by the relatively small respondent pool, which represented only 26% of sports medicine fellowship programs in the United States.

Over the past two decades, intermittent hypoxic training (IHT), that is, a method where athletes live at or near sea level but train under hypoxic conditions, has gained unprecedented popularity. By adding the stress of hypoxia during 'aerobic' or 'anaerobic' interval training, it is believed that IHT would potentiate greater performance improvements compared to similar training at sea level. A thorough analysis of studies including IHT, however, leads to strikingly poor benefits for sea-level performance improvement, compared to the same training method performed in normoxia. Despite the positive molecular adaptations observed after various IHT modalities, the characteristics of optimal training stimulus in hypoxia are still unclear and their functional translation in terms of whole-body performance enhancement is minimal. To overcome some of the inherent limitations of IHT (lower training stimulus due to hypoxia), recent studies have successfully investigated a new training method based on the repetition of short (training in hypoxia (RSH). The aims of the present review are therefore threefold: first, to summarise the main mechanisms for interval training and repeated sprint training in normoxia. Second, to critically analyse the results of the studies involving high-intensity exercises performed in hypoxia for sea-level performance enhancement by differentiating IHT and RSH. Third, to discuss the potential mechanisms underpinning the effectiveness of those methods, and their inherent limitations, along with the new research avenues surrounding this topic.

The study was undertaken to evaluate the education and training background of Canadian registered dietitians (RDs) practising in sport and exercise nutrition, as well as learning opportunities in the practice area. A secondary analysis of a 2009 Dietitians of Canada (DC) Sport Nutrition Network survey of members (n=70) was conducted to describe members' educational background. Through the use of publicly available information, Canadian dietetic internship, undergraduate, and graduate sport nutrition educational opportunities were identified. Most (72.9%) respondents indicated they had some type of formal education in sport nutrition; learning from undergraduate courses and conference sessions was cited most frequently. The majority (86.7%) of accredited universities offered undergraduate courses in sport/exercise nutrition. No DC-accredited internship program offered sport nutrition as a mandatory rotation, while 15.8% of graduate programs in Canada had faculty with research interests in the area. Among respondents, 91.4% felt sport nutrition education in Canada was inadequate; all expressed interest in participating in more formal learning experiences, and 97.1% were interested in a specialized credential. Canadian dietitians working in sport and exercise nutrition have diverse educational backgrounds and must direct their own learning. Improved career development pathways and more available formal education are desired and needed.

The aim of this review was to identify the main variables for load monitoring in training and competition situations in wheelchair sports. Studies were identified from a systematic search of three databases (PubMed, Web of Science, and SportDiscuss), with search phrases constructed from MeSH terms, alone or in combination, limited to English-language literature, and published up to January 2016. Our main findings were that variables related to external load (distance, speed, and duration) are used to monitor load in competition. In training situations, researchers have used variables related to internal load (heart rate and VO 2 ); in both training and competition situations, researchers used internal load measurements (training impulse and ratings of perceived exertion). We conclude that the main variables for load monitoring in competitive situations were distance, speed, and duration, whereas the variables for training situations were heart rate, VO 2 , training impulse, and ratings of perceived exertion.

Youth have very high participation and injury rates in sport. Sport is the leading cause of injury in youth. Sport injury reduces future participation in physical activity which adversely affects future health. Sport injury may lead to overweight/obesity and post-traumatic osteoarthritis. The objective of the systematic review and meta-analysis was to evaluate the efficacy of injury prevention neuromuscular training strategies in youth sport. Three electronic databases were systematically searched up to September 2014. Studies selected met the following criteria: original data; analytic prospective design; investigated a neuromuscular training prevention strategy intervention(s) and included outcomes for injury sustained during sport participation. Two authors assessed the quality of evidence using Downs and Black (DB) criteria. Meta-analyses including randomised controlled trials only (RCTs) to ensure study design homogeneity were completed for lower extremity and knee injury outcomes. Of 2504 potentially relevant studies, 25 were included. Meta-analysis revealed a combined preventative effect of neuromuscular training in reducing the risk of lower extremity injury (incidence rate ratio: IRR=0.64 (95% CI 0.49 to 0.84)). Though not statistically significant, the point estimate suggests a protective effect of such programmes in reducing the risk of knee injury (IRR=0.74 (95% CI 0.51 to 1.07)). There is evidence for the effectiveness of neuromuscular training strategies in the reduction of injury in numerous team sports. Lack of uptake and ongoing maintenance of such programmes is an ongoing concern. A focus on implementation is critical to influence knowledge, behaviour change and sustainability of evidence informed injury prevention practice. Published by the BMJ Publishing Group Limited.

Cardiovascular effects of an artificial gravity (AG) countermeasure on deconditioned male volunteers were studied. In two groups of men we measured cardiovascular parameters at rest and in response to 30 minutes of 80 deg. head up tilt (HUT) before, at the end of, and four days following 21 days of 6 deg. head down bed rest (HDBR). One group (N=7) underwent no countermeasure while the other (N=8) received a daily, one hour, dose (2.5 gz at the foot, decreasing to 1.0 gz at the heart) of AG training on the Johnson Space Center short radius centrifuge. Cardiovascular parameters measured included heart rate, blood pressure, stroke volume, cardiac output, peripheral vascular resistance, plasma volume shifts, and vasoactive hormones. Untrained subjects exhibited shorter tilt survival (on average 8 minutes shorter) compared to trained subjects. By the end of bed rest, mean heart rate (MHR) was elevated in both groups (both supine and during tilt). In addition, treated subjects demonstrated lower, tilt-induced, increases in MHR four days following HDBR, indicating a more rapid return to pre bed rest conditions. Results from an index of autonomic balance (percentage of MHR spectral power in the respiratory frequency range) in control of heart rate are consistent with the interpretation that parasympathetic nervous system withdrawal was responsible for both tilt- and bed rest-induced increases in MHR. Our data support our pre-study hypothesis that AG treatment would lessen cardiovascular effects of deconditioning in bed rested men and suggest that AG should be further pursued as a space flight countermeasure.

Influence of gender and sports training on QT variables such as QT interval and dispersion (QT dispersion: QTD) in young elite athletes were evaluated. Subjects included 104 male and 97 female Japanese elite athletes (mean age 21.6 years). Sports included basketball, fencing, gymnastics, judo, swimming, tennis, track and field and volleyball. Age-matched healthy non-athletes (32 men and 20 women) were enrolled as controls. QT measurements were manually obtained from a 12-lead resting electrocardiogram and QTD was calculated as the difference between the longest and shortest QT intervals. A corrected QT interval (QTc) was obtained using Bazett's formula. Subjects were divided into two groups; an endurance training group and a static training group on the basis of their training types. Maximum and minimum QTc were significantly longer in female athletes than in male athletes (max: 414.2 vs. 404.5 ms, min: 375.1 vs. 359.2 ms, ptraining group compared with non-athletes, and QTcDs in the static training group were prolonged compared with the endurance training group. However, no significant difference was observed in the female group. In conclusion, both gender and different characteristics of sports training may affect QT variables even in young elite athletes. Vigorous static exercise training may independently prolong QT variables.

An effective training plan is an important factor in sports training to enhance athletic performance. A poorly considered training plan may result in injury to the athlete, and overtraining. Good training plans normally require expert input, which may have a cost too great for many athletes, particularly amateur athletes. The objectives of this research were to create a practical cycling training plan that substantially improves athletic performance while satisfying essential physiological constraints. Adaptive Particle Swarm Optimization using ɛ-constraint methods were used to formulate such a plan and simulate the likely performance outcomes. The physiological constraints considered in this study were monotony, chronic training load ramp rate and daily training impulse. A comparison of results from our simulations against a training plan from British Cycling, which we used as our standard, showed that our training plan outperformed the benchmark in terms of both athletic performance and satisfying all physiological constraints.

Plyometric training (PT) is a very popular form of physical conditioning of healthy individuals that has been extensively studied over the last decades. In this article, we critically review the available literature related to PT and its effects on physical fitness in team sport athletes. We also considered studies that combined PT with other popular training modalities (e.g. strength/sprint training). Generally, short-term PT (i.e. 2-3 sessions a week for 4-16 weeks) improves jump height, sprint and agility performances in team sport players. Literature shows that short PT (plyometric exercises and the bilateral and unilateral jumps could improve these performances more than the use of single plyometric drills or traditional PT. Thus, the present review shows a greater effect of PT alone on jump and sprint (30 m sprint performance only) performances than the combination of PT with sprint/strength training. Although many issues related to PT remain to be resolved, the results presented in this review allow recommending the use of well-designed and sport-specific PT as a safe and effective training modality for improving jumping and sprint performance as well as agility in team sport athletes.

Regular participation in organized youth sports does not ensure adequate exposure to skill- and health-related fitness activities; and sport training without preparatory conditioning does not appear to reduce risk of injury in young athletes. Recent trends indicate that widespread participation in organized youth sports is occurring at a younger age, especially in girls. Current public health recommendations developed to promote muscle strengthening and bone building activities for youth aged 6 and older, along with increased involvement in competitive sport activities at younger ages, has increased interest and concern from parents, clinicians, coaches and teachers regarding the optimal age to encourage and integrate more specialized physical training into youth development programs. This review synthesizes the latest literature and expert opinion regarding when to initiate neuromuscular conditioning in youth and presents a how to integrative training conceptual model that could maximize the potential health-related benefits for children by reducing sports-related injury risk and encouraging lifelong regular physical activity.

In order to guarantee an effective and punctual medical intervention to injured people involved in health emergency situations, where usually both professional and non-professional health operators are involved, a fast and accurate treatment has to be carried out. In case of catastrophic or very critical situations, non-professional operators who did not receive proper training (volunteers are among them) could be affected by psychological inhibitions. Their performances could slow down in such way that would affect the quality of the treatment and increase both direct and indirect costs. Our virtual reality system that is currently in use at the health care emergency center of San Martino Hospital in Genoa, Italy, has been designed and developed to check health emergency operators' capabilities to adopt correct decision-making procedures, to make optimal use of new technological equipment and to overcome psychological barriers. Our system is composed of (1) a high-end simulation PC, whose main functions are execution of the main software module, rendering of 3D scenes in stereo mode, rendering of sound, and control of data transmission from/to VR devices; (2) a low-end control PC, which controls the VR simulation running on the simulation PC, manages medical emergency simulation scenarios, introduces unexpected events to the simulation and controls the simulation difficulty level; (3) a magnetic-based motion tracking device used for head and hand tracking; (4) a wireless pair of shutter glasses together with a cathode ray tube wall projector; and (5) a high-end surround sound system. The expected benefits have been verified through the design and implementation of controlled clinical trials.

Recommendations exist to encourage safe youth participation in sport. These recommendations include not specializing in 1 sport, limiting participation to less than 8 months per year, and limiting participation to fewer hours per week than a child's age. However, limited evidence exists to support or refute these recommendations. High levels of specialization will be associated with a history of injuries and especially overuse injuries, independent of age, sex, or weekly sport training hours. Athletes who exceed current sport volume recommendations will be more likely to have a history of injuries and overuse injuries. Case-control study; Level of evidence, 3. Youth athletes (n = 2011; 989 female and 1022 male; 12-18 years of age) completed a questionnaire regarding their specialization status, yearly and weekly sport participation volume, and injury history. Specialization was classified as low, moderate, or high using a previously utilized 3-point scale. Athletes were classified into groups based on either meeting or exceeding current volume recommendations (months per year and hours per week). Odds ratios (ORs) and 95% CIs were calculated to investigate associations of specialization and volume of participation with a history of sport-related injuries in the past year ( P ≤ .05). Highly specialized athletes were more likely to report a previous injury of any kind ( P sport more than 8 months of the year were more likely to report an upper extremity overuse injury ( P = .04; OR, 1.68; 95% CI, 1.06-2.80) or a lower extremity overuse injury ( P = .001; OR, 1.66; 95% CI, 1.22-2.30). Athletes who participated in their primary sport for more hours per week than their age (ie, a 16-year-old athlete who participated in his or her primary sport for more than 16 h/wk) were more likely to report an injury of any type ( P = .001; OR, 1.34; 95% CI, 1.12-1.61) in the previous year. High levels of specialization were associated with a history of injuries, independent of age

Due to the broad spectrum of physical characteristics necessary for success in field sports, numerous training modalities have been used develop physical preparedness. Sports like rugby, basketball, lacrosse, and others require athletes to be not only strong and powerful but also aerobically fit and able to recover from high-intensity intermittent exercise. This provides coaches and sport scientists with a complex range of variables to consider when developing training programs. This can often lead to confusion and the misuse of training modalities, particularly in the development of aerobic and anaerobic conditioning. This review outlines the benefits and general adaptations to 3 commonly used and effective conditioning methods: high-intensity interval training, repeated-sprint training, and small-sided games. The goals and outcomes of these training methods are discussed, and practical implementations strategies for coaches and sport scientists are provided.

Leadership development programs are common in sports, but seldom evaluated; hence, we have limited knowledge about what the participants actually learn and the impact these programs have on sports clubs' daily operations. The purpose of the current study was to integrate a transfer of training model with self-determination theory to understand predictors of learning and training transfer, following a leadership development program among organizational leaders in Swedish sports clubs. Bayesian multilevel path analysis showed that autonomous motivation and an autonomy-supportive implementation of the program positively predicted near transfer (i.e., immediately after the training program) and that perceiving an autonomy-supportive climate in the sports club positively predicted far transfer (i.e., 1 year after the training program). This study extends previous research by integrating a transfer of training model with self-determination theory and identified important motivational factors that predict near and far training transfer.

The purpose of this study was to determine the level of knowledge that current and preservice high school (HS) physical educators and sport coaches possess regarding the principles and methods involved in youth resistance training (RT) and to determine if that knowledge was acceptable based on a predetermined criterion (passing score). A panel of 10 experts in RT or sport pedagogy used a Delphi technique to create a 90-question assessment (examination) that was administered to 287 HS physical educators and sport coaches and 140 university physical education teacher education (PETE) students. An analysis of the results revealed that neither group demonstrated the minimal knowledge necessary to design, implement, and supervise RT programs based on a passing score of 75%: HS physical educators/coaches, mean = 59.30, SD = 14.30, 95% confidence interval (CI) = 57.64-60.96], t(286) = -18.61, p = 0.000; university PETE students, mean = 56.61, SD = 16.59, 95% CI = 53.84-59.38, t(139) = -13.12, p = 0.000. The pass rate for physical educators and sport coaches was 14.3% and for university PETE students it was 20.7%. The results of this study indicate that both current and preservice physical educators and sport coaches need additional education and training specific to the design and implementation of RT programs for HS students. Given that school districts typically require their educators attend in-service training programs, it may be advisable to develop an in-service program that allows both current and preservice HS physical educators and sport coaches to earn an RT certification that specifically addresses the unique physical and psychosocial needs of school-aged youth.

Cardiopulmonary resuscitation (CPR) is a sudden emergency procedure that requires a rapid and efficient response, and personnel training in lifesaving procedures. Regular practice and training are necessary to improve resuscitation skills and reduce anxiety among the staff. As one of the most important skills mastered by medical volunteers serving for Mt. Taishan International Mounting Festival, we randomly selected some of them to evaluate the quality of CPR operation and compared the result with that of the untrained doctors and nurses. In order to evaluate the functions of repeating standard CPR training on performance qualities of medical volunteers for Mt. Taishan International Mounting Festival, their performance qualities of CPR were compared with those of the untrained medical workers working in emergency departments of hospitals in Taian. The CPR performance qualities of 52 medical volunteers (Standard Training Group), who had continually taken part in standard CPR technical training for six months, were tested at random and were compared with those of 68 medical workers (Compared Group) working in emergency departments of hospitals in Taian who hadn't attended CPR training within a year. The QCPR 3535 monitor (provided by Philips Company) was used to measure the standard degree of single simulated CPR performance, including the chest compression depth, frequency, released pressure between compressions and performance time of compression and ventilation, the results of which were recorded in the table and the number of practical compression per minute was calculated. The data were analyzed by x2 Test and t Test. The factors which would influence CPR performance, including gender, age, placement, hand skill, posture of compression and frequency of training, were classified and given parameters, and were put to Logistic repression analysis. The CPR performance qualities of volunteers were much higher than those of the compared group. The overall pass rates

Binocular vision is the most important visual cue for spatial orientation in many sports. In this study, we investigated how binocular vision was influenced by an eye training program that may be used to improve individual's oculomotor function. The experiment involved twenty-four female student athletes from team ball sports (soccer, basketball, handball). After an initial testing session, 12 participants were randomly allocated to the experimental group. Optometric investigation which included synoptophore testing and a test of dissociated horizontal phoria based on the Maddox method was performed three times: before the experiment, after eight weeks of eye training (3 times a week for 20 minutes), and four weeks after the experiment was terminated. Eye exercise methodology was based on orthoptic, sport and psychological aspects of performance. The phoria screening examination showed that exophoria was the most frequent disorder of binocular vision. Low fusional vergence range was also observed. Following the training period, 3 of the 6 oculomotor variables improved. The greatest effect was observed in near dissociated phoria (χ(2) =14.56, p=0.001 for the right eye; χ(2) =14.757, p=0.001 for the left eye) and fusional convergence (χ(2) =8.522, p=0.014). The results of the retention test conducted four weeks after the experiment confirmed the effectiveness of the vision training program. The results of the study suggest that binocular functions are trainable and can be improved by means of appropriate visual training.
Full Text Available Plyometric training (PT is a very popular form of physical conditioning of healthy individuals that has been extensively studied over the last decades.

We also considered studies that combined PT with other popular training modalities (e.g. strength/sprint training. Generally, short-term PT (i.e. 2-3 sessions a week for 4-16 weeks improves jump height, sprint and agility performances in team sport players. Literature shows that short PT (<8 weeks has the potential to enhance a wide range of athletic performance (i.e. jumping, sprinting and agility in children and young adult amateur players. Nevertheless, 6 to 7 weeks training appears to be too short to improve physical performance in elite male players. Available evidence suggests that short-term PT on non-rigid surfaces (i.e. aquatic, grass or sand-based PT could elicit similar increases in jumping, sprinting and agility performances as traditional PT. Furthermore, the combination of various plyometric exercises and the bilateral and unilateral jumps could improve these performances more than the use of single plyometric drills or traditional PT. Thus, the present review shows a greater effect of PT alone on jump and sprint (30 m sprint performance only performances than the combination of PT with sprint/strength training. Although many issues related to PT remain to be resolved, the results presented in this review allow recommending the use of well-designed and sport-specific PT as a safe and effective training modality for improving jumping and sprint performance as well as agility in team sport athletes.

There is overwhelming evidence, particularly from echocardiography, that the heart of competitive athletes may differ from that of nonathletes, matched for age, gender, and body size. A larger left ventricular mass has been shown in athletes performing predominantly dynamic aerobic and anaerobic sports, in athletes engaged in static training, and in players of ball sports. Enlargement of the left ventricular internal diameter was most pronounced and reached about 10% in athletes performing predominantly dynamic sports; mainly strength training athletes had a lesser increase of the internal dimension, which was limited to 2.5%. Also the left ventricular wall appeared to be thickened in all types of athletes compared with controls. In sports with high dynamic and low static demands, wall thickness was proportionate or slightly disproportionate to the size of the internal diameter so that relative wall thickness was not different from controls or slightly increased (predominantly eccentric hypertrophy). In strength athletes, the disproportionate increase of wall thickness averaged about 12% (predominantly concentric hypertrophy). In sports with high dynamic and high static demands and requiring prolonged training, such as cycling, the increases of absolute and relative wall thickness reached 29% and 19% and were more pronounced than in runners (mixed hypertrophy). A plausible interpretation of these results is that the development of so-called eccentric or concentric left ventricular hypertrophy according to the type of sports cannot be regarded as an absolute or dichotomous concept because training regimens and sports activities are not exclusively dynamic or static and because the load on the heart is not purely of the volume or the pressure type. Most studies agree that left ventricular systolic and diastolic function is normal in the athlete at rest, whereas diastolic function seems to be enhanced in the exercising endurance athlete. The consistency of the results

Full Text Available The high demand in athletes creates the need to control the process of adaptation to training. The aim of this review is to analyze the biochemical parameters of utility for biological control of the athlete, and provide tools to sports dietitian-nutritionist in the follow-up of the training.Glucose and lipid profile parameters are widely used but insufficient to control training. The lactic acid level in the plasma is the most common tool to assess training load, where values higher than 4 mmol/l, suggest an intensive training. Other enzymes in high concentrations such as creatine kinase (CK, lactate dehydrogenase (LDH and two transaminases: glutamic oxaloacetic transaminase (GOT or aspartate transaminase (AST or aspartate aminotransferase (AAT and glutamic pyruvic transaminase (GPT or alanine transaminase or aminotransferase (ALT suggest that the training load was high producing microscopic tearing of the muscle fibers. Determination of other substrates such as ammonia, glutamine, or testosterone/cortisol ratio, used to detect a possible overtraining syndrome. Likewise the latest research suggest that high cortisol levels decrease the immune system.Moreover, an increase of urea, alanine or ketone bodies are related to muscle glycogen stores depleted. Therefore, the information provided by these parameters is useful for the sports dietitian-nutritionist for dietary and nutritional interventions to achieve more effective in function of the training goals.

The principal source of increased turnover of erythrocytes in athletes is sport hemolysis, the intravascular hemolysis that characteristically occurs with athletic performance in sport. The use of the parameter mean sphered cell volume (MSCV), automatically measured by means of the Coulter LH750, could be useful for diagnosing the presence of sport hemolysis. We studied the behavior of MSCV and mean corpuscular volume (MCV) in 30 top-level rugby players who underwent a heavy training session followed by 3 different recovery methods, administered to 3 subgroups of 10 athletes. We tested the use of active recovery consisting of cold water (5 degrees C) immersion of legs for 10 minutes either before (n = 10) or after (n = 10) cycling at 180 W for 10 minutes. In the whole group of athletes, measurements performed at rest and after training session and recovery showed no differences in MCV and MSCV values. The difference between MCV and MSCV was significant in the whole group and in the subgroup performing passive recovery, whereas the difference was not significant in the subgroups performing active recovery. This finding indicates that the use of active recovery in the top-level rugby players prevented the modifications of erythrocyte volume and shape. We outline that the values of the difference between MCV and MSCV was significantly modified in the whole group but the variations were not significant in the active recovery subgroups. The use of an index of erythrocyte shape modification (MCV - MSCV) can be very useful for evaluating sport hemolysis.

Hamstring strain injuries are endemic in running-based sports. Given the economic and performance implications of these injuries, a significant body of research has emerged in recent years in an attempt to identify risk factors and develop or optimise injury prevention strategies. Surveys of injury prevention practices among medical and conditioning staff in elite sport suggest that many sporting clubs invest significant efforts in eccentric hamstring conditioning and lumbo-pelvic or trunk stability programmes. The purpose of this narrative review was to critically evaluate the evidence underpinning these practices. Single-exercise eccentric training interventions have proven effective in the prevention of primary and recurrent hamstring strains, when compliance is adequate. However, despite its almost universal acceptance, the authors are aware of only one, very recent, prospective risk factor study examining the effect of lumbo-pelvic motion during sprinting on hamstring injury risk. Furthermore, the interventions exploring the effect of lumbo-pelvic training on hamstring injury rates have not measured stability in any way. An improved understanding of the evidence underpinning commonly employed hamstring injury prevention practices may enable clinicians and coaches to better prioritise effective strategies in the increasingly complex environment of elite sport.

Previous research has shown a weak relationship between intended and actual training load in various sports. Due to variety in group and content, this relationship is expected to be even weaker during group rehabilitation. The goal of this study was to examine the relationship between intended and actual training load during sport-specific rehabilitation in a group setting. Observational study. Three outdoor rehabilitation sessions. Nine amateur soccer players recovering from lower limb injury participated in the study (age 22 ± 3 y, height 179 ± 9 cm, body mass 75 ± 13 kg). We collected physiotherapists' ratings of intended exertion (RIE) and players' ratings of perceived exertion (RPE). Furthermore, Zephyr Bioharness 3 equipped with GPS-trackers provided heart rate and distance data. We computed heart rate-based training loads using Edwards' method and a modified TRIMP. Overall, we found weak correlations (N = 42) between RIE and RPE (r = 0.35), Edwards' (r = 0.34), TRIMP MOD (r = 0.07), and distance (r = 0.26). In general, physiotherapists tended to underestimate training loads. To check whether intended training loads are met, it is thus recommended to monitor training loads during rehabilitation.

Small-sided games (SSGs) incorporating skills, sport-specific movements, at intensities sufficient to promote aerobic adaptations, are being increasingly implemented in professional team sport environments. Small-sided games are often employed by coaches based on the premise that the greatest training benefits occur when training simulates the specific movement patterns and physiological demands of the sport. At present, there is relatively little information regarding how SSG can best be used to improve physical capacities and technical and tactical skills in team sports. It is possible that with some modifications (e.g., number of players, pitch size, coach encouragement, and wrestling), such games may be physiologically beneficial for athletes with relatively high initial aerobic fitness levels. For instance, it has been shown that 3-a-side soccer SSG resulted in higher intensity (i.e., greater overall distance, less jogging and walking, higher heart rate, and more tackling, dribbling, goal attempts, and passes) than 5-a-side SSG. Likewise, when player numbers were kept constant, a larger playing area increased the intensity of the SSG with a smaller playing area having the opposite effect. It has also been demonstrated that energy expenditure was similar between badminton and volleyball courts, but lower than that obtained in a basketball court. Moreover, it has been demonstrated in rugby that wrestling can increase the physical demands of SSG. Consistent coach encouragement can also increase training intensity, although most rule changes have trivial or no effect on exercise intensity. Further research is required to examine the optimal periodization strategies of SSG training for the long-term development of physiological capacity, technical skill, and tactical proficiency, while also minimizing the associated risk of injuries.
Full Text Available Objectives. This paper aims at exploring the effects of GUASHA on heart rate variability between healthy volunteers under normal condition and weightlifters after training sessions. Methods. Ten healthy male volunteers under normal condition and 15 male weightlifters after weightlifting training sessions were recruited into two groups. Electrocardiography was recorded before and immediately after 20-minute GUASHA. HRV was calculated in both the time domain and the frequency domain. Results. Stress index was reduced, while standard deviation of N-N intervals (SDNN, proportion derived by dividing the number of interval differences of successive N-N intervals greater than 50 ms, and root mean square of successive differences (RMSSD were enhanced after GUASHA therapy in the two groups. The changes in SDNN and RMSSD were higher in the healthy men group than in the weightlifters group. In addition, low frequency was decreased whereas high frequency was significantly increased in healthy men after the GUASHA session. Conclusions. GUASHA therapy facilitates the parasympathetic nervous activity and modulates the balance between parasympathetic and sympathetic activities in both healthy men under normal condition and weightlifters after training sessions as indicated. Although the changes of the HRV parameters were similar in both groups, the responsiveness was more pronounced in healthy men than in male weightlifters.

Full Text Available The aim of the study was to compare oxidative/antioxidative status in obese and sport trained children and to correlate obtained redox markers with anthropometrical measurements, body composition parameters, and adipokines levels. 78 (44 males obese (SG and 80 (40 males normal weight sport trained (CG children matched for age and Tanner stage were recruited for the study. Body composition parameters and basal metabolic rate (BMR were assessed by bioelectrical impedance analysis (BIA. Oxidative/antioxidative status was evaluated in plasma by total oxidative status (PerOX, oxidized-LDL cholesterol (oxLDL, total antioxidative capacity (ImAnOx, and glutathione peroxidase activity (GPx. Leptin and adiponectin levels and adiponectin/leptin ratio (A/L were also investigated. OxLDL was higher in SG versus CG (P < 0.05, but ImAnOx and GPx were reduced in SG versus CG (P < 0.01. Redox markers correlated significantly with BMI Z-score, WHR, WHtR, body composition parameters, leptin (in boys only, and A/L ratio (in boys only in SG and in a whole studied population. PerOX significantly correlated with BMR in the CG. Antioxidative/oxidative status in obese children is significantly impaired and related adipose tissue excess and its hormonal activity. Oxidative status assessed by PerOx is also high in sport trained children but antioxidative defense is significantly more efficient with no overproduction of oxidized LDL.
Full Text Available Introduction. Gaining insight into the mechanisms and scope of possible adaptations of visual functions to the conditions determined by the demands imposed by sports training seems to be very interesting not only from a cognitive point of view, but also with respect to the practical applications of the findings of such investigations in the training process. The aim of the study was to assess the function of early visual processing in athletes representing different sports disciplines with varying training experience. Material and methods. The study involved 95 athletes practising football (n = 24, volleyball (n = 22, boxing (n = 26, and rowing (n = 23. The bioelectric function of the visual pathway was assessed based on recordings of visual evoked potentials (VEPs. The regions which were stimulated were the peripheral and central areas of the retina. During the test, we recorded the amplitude (μV and latency (ms of the P100 component of the VEP waveform for both monocular stimulation (for the dominant and non-dominant eye and binocular stimulation. Results. Lower VEP P100 amplitude values were found for the peripheral and central locations for monocular and binocular viewing in more experienced volleyball players and rowers (p 0.05 in intragroup variability in VEP P100 latency in relation to training experience in any of the sports disciplines examined. Conclusions. Training experience has an influence on the early stage of sensory processing with respect to neural activity. Training experience has been found to differentiate athletes in terms of the temporal parameters of the visual evoked potentials recorded in the current study only to a limited extent.

The purpose of this meta-analysis was to study the short-term adaptations on sprint and vertical jump (VJ) performance following Complex Training (CT) in team-sports. CT is a resistance training method aimed at developing both strength and power, which has a direct effect on sprint and VJ. It consists on alternating heavy resistance training exercises with plyometric/power ones, set for set, on the same workout. A search of electronic databases up to July 2016 (PubMed-MEDLINE, SPORTDiscus, Web of Knowledge) was conducted. Inclusion criteria: 1) at least one CT intervention group; 2) training protocols ≥4-wks; 3) sample of team-sport players; 4) sprint or VJ as an outcome variable. Effect sizes (ES) of each intervention were calculated and subgroup analyses were performed. A total of 9 studies (13 CT groups) met the inclusion criteria. Medium effect sizes (ES) (ES = 0.73) were obtained for pre-post improvements in sprint, and small (ES = 0.41) in VJ, following CT. Experimental-groups presented better post-intervention sprint (ES = 1.01) and VJ (ES = 0.63) performance than control-groups. large ESs were exhibited in younger athletes (training programs >12 total sessions (ES = 0.74). Large ESs in programs with >12 total sessions (ES = 0.81). Medium ESs obtained for under-Division I individuals (ES = 0.56); protocols with intracomplex rest intervals ≥2 min (ES = 0.55); conditioning activities with intensities ≤85% 1RM (ES = 0.64); basketball/volleyball players (ES = 0.55). Small ESs were found for younger athletes (ES = 0.42); interventions ≥6 weeks (ES = 0.45). CT interventions have positive medium effects on sprint performance and small effects on VJ in team-sport athletes. This training method is a suitable option to include in the season planning.

Team Sports has been suggested as a suitable environment to investigate creative behavior. This study's purpose was two-fold: first, it intended to identify the effects of the Skills4Genius sports-bases training program in thinking, motor, and in-game creative behavior in team sports. Second, it aimed to investigate the relationship between creative thinking and in-game creativity. Forty children from primary school were allocated into control (n = 18, age: 9.2±0.4) and experimental (n = 22, age: 9.5±0.7) groups. The experimental group participated in a five-month training program involving either creative thinking, diversification, physical literacy, and nonlinear pedagogy approaches (Skills4Genius). Variables in the study included: a) creative thinking; b) motor performance (vertical jump, speed, and agility); c) in-game individual creative behavior (attempts, fluency, and versatility); and d) in-game collective behavior (positional regularity). The results suggested that the Skills4Genius program fostered creative thinking, agility, and speed performance. Moreover, it stretched the in-game individual creative behavior mainly through the improvement of the attempts and versatility of the player's actions. Lastly, it nurtured a better learning of the tactical principles, whereas the children were more coordinated with their teammates' and opponents' positioning. Additionally, this study presents a positive correlation linking creative thinking and in-game creative performance. These findings highlighted that creativity is facilitated while players become more thinking and game-skilled. Coaches and educators may apply this functional environment to inspire children's disposition to move outside the box and trigger a creative spark in team sports players. Notwithstanding, the sports environment is ideally suited for fostering creative behavior, a higher-order disposition that will go on to differentiate the everyday life of a child.

This paper examines the phenomenon of training teachers of Physical Education and Sports (PES) in Turkey with respect to its dimensions of student quotas, graduates, and employment; and performs analytical evaluations through the numeric data. In the last five years, the number of labor force participants in PES teaching posts was 14,459 on average and the average employment volume was 10.29%, which means that a great number of graduates have accumulated against employment. Thus, this indicates that no realistic planning was done in the past years "so as to create a supply-demand equilibrium between training and employment of PES teachers".

Full Text Available Athletes' performances are influenced by internal and external factors, including their psychological state and environmental factors, especially during competition. As a consequence, current training programs include stress management. In this paper, we explore whether highly immersive systems can be used for such training programs. First, we propose methodological guidelines to design sport training scenarios both on considering the elements that a training routine must have, and how external factors might influence the participant. The proposed guidelines are based on Flow and social-evaluative threat theories. Second, to illustrate and validate our methodology, we designed an experimental setup reproducing a ten meter Olympic pistol shooting. We analyzed whether changes in the environment are able to induce changes in user performance, physiological responses and the subjective perception of the task. The simulation included stressors in order to raise a social-evaluative threat, such as aggressive public behavior or unforced errors, increasing the pressure while performing the task. The results showed significant differences in their subjective impressions, trends in the behavioral and physiological data were also observed. Taken together, our results suggest that highly immersive systems could be further used for training in sports.
Training quantification is basic to evaluate an endurance athlete's responses to training loads, ensure adequate stress/recovery balance, and determine the relationship between training and performance. Quantifying both external and internal workload is important, because external workload does not measure the biological stress imposed by the exercise sessions. Generally used quantification methods include retrospective questionnaires, diaries, direct observation, and physiological monitoring, often based on the measurement of oxygen uptake, heart rate, and blood lactate concentration. Other methods in use in endurance sports include speed measurement and the measurement of power output, made possible by recent technological advances such as power meters in cycling and triathlon. Among subjective methods of quantification, rating of perceived exertion stands out because of its wide use. Concurrent assessments of the various quantification methods allow researchers and practitioners to evaluate stress/recovery balance, adjust individual training programs, and determine the relationships between external load, internal load, and athletes' performance. This brief review summarizes the most relevant external- and internal-workload-quantification methods in endurance sports and provides practical examples of their implementation to adjust the training programs of elite athletes in accordance with their individualized stress/recovery balance.

To compare the effects of combining high-intensity training (HIT) and sport-specific drill training (MT) versus sportspecific drill training alone (DT) on fitness performance characteristics in young tennis players. Twenty young tennis players (14.8 ± 0.1 y) were assigned to either DT (n = 10) or MT (n = 10) for 8 wk. Tennis drills consisted of two 16- to 22-min on-court exercise sessions separated by 3 min of passive rest, while MT consisted of 1 sport-specific DT session and 1 HIT session, using 16-22 min of runs at intensities (90-95%) related to the velocity obtained in the 30-15 Intermittent Fitness Test (V IFT ) separated by 3 min of passive rest. Pre- and posttests included peak oxygen uptake (VO 2 peak), V IFT , speed (20 m, with 5- and 10-m splits), 505 Agility Test, and countermovement jump (CMJ). There were significant improvements after the training period in VO 2 peak (DT 2.4%, ES = moderate; MT 4.2%, ES = large) and V IFT (DT 2.2%, ES = small; MT 6.3%, ES = large) for both DT and MT, with no differences between training protocols. Results also showed a large increase in the 505 Agility Test after MT, while no changes were reported in the other tests (sprint and CMJ), either for MT or DT. Even though both training programs resulted in significant improvements in aerobic performance, a mixed program combining tennis drills and runs based on the V IFT led to greater gains and should be considered the preferred training method for improving aerobic power in young athletes.

We recorded eye movements of eight elite junior basketball players. We hypothesized that a more stable gaze is correlated to a better shot rate. Upon preliminary testing we invited male juniors whose eyes could be reliably tracked in a game situation. To these ends, we used a head-mounted video-based eye tracker. The participants had no record of ocular or other health issues. No significant differences were found between shots made with and without the tracker cap, Paired samples t-test yielded p= .130 for the far and p=..900 > .050 for the middle range shots. The players made 40 shots from common far and middle range locations, 5 and 4 meters respectively for aged 14 years As expected, a statistical correlation was found between gaze fixation (in milliseconds) for the far and middle range shot rates, r=.782, p=.03. Notably, juniors who fixated longer before a shot had a more stable fixation or a lower gaze dispersion (in tracker's screen pixels), r=-.786, p=.02. This finding was augmented by the observation that the gaze dispersion while aiming at the basket was less (i.e., gaze more stable) in those who were more likely to score. We derived a regression equation linking fixation duration to shot success. We advocate infra-red eye tracking as a means to monitor player selection and training success.

We assessed the feasibility and impact on knowledge, attitudes, and reported practices of psychological first-aid (PFA) training in a sample of Medical Reserve Corps (MRC) members. Data have been limited on the uptake of PFA training in surge responders (eg, MRC) who are critical to community response. Our mixed-methods approach involved self-administered pre- and post-training surveys and within-training focus group discussions of 76 MRC members attending a PFA training and train-the-trainer workshop. Listen, protect, connect (a PFA model for lay persons) focuses on listening and understanding both verbal and nonverbal cues; protecting the individual by determining realistic ways to help while providing reassurance; and connecting the individual with resources in the community. From pre- to post-training, perceived confidence and capability in using PFA after an emergency or disaster increased from 71% to 90% (P training. Brief training was feasible, and while results were modest, the PFA training resulted in greater reported confidence and perceived capability in addressing psychological distress of persons affected by public health threats. PFA training is a promising approach to improve surge responder confidence and competency in addressing postdisaster needs.

Residency training clearly impacts physicians' approach toward fellowship in Primary Care Sports Medicine. Although the Accreditation Council for Graduate Medical Education sets strict standards for all programs, family medicine and emergency medicine training differ a great deal in general and provide physicians from both backgrounds varied perspectives and skill sets. The family physician acquires a substantial amount of experience in continuity of care and integration of health care into a patient's everyday life. On the other hand, the emergency physician receives exceptional training in the management of acutely ill and injured patients and leadership of a large health care team. Furthermore, while the emergency physician may be skilled in procedures such as fracture reduction and diagnostic ultrasound, the family physician is proficient in developing patient rapport and compliance with a treatment plan. Although physicians from different backgrounds may start with many differences, fellowship training is essential in bridging those gaps.

(The conceptual and empirical foundations of empowering coaching TM : Setting the stage for the PAPA project. International Journal of Sport and Exercise Psychology, 11, 311-318. doi:10.1080/1612197X.2013.839414), the aim of the current study was to observe empowering and disempowering features of the multidimensional motivational coaching environment in training and competition in youth sport. Seventeen grass-roots soccer coaches were observed and rated in training and competitive settings using the multidimensional motivational climate observation system (MMCOS; Smith, N., Tessier, D., Tzioumakis, Y., Quested, E., Appleton, P., Sarrazin, P., … Duda, J. L. (2015). Development and validation of the multidimensional motivational climate observation system (MMCOS). Journal of Sport and Exercise Psychology, 37, 4-22. doi:10.1123/jsep.2014-0059). In line with our hypotheses, coaches created different motivational environments in the two contexts. More specifically, coaches were observed to create a less empowering and more disempowering environment in competition compared to in training. The observed differences were underpinned by distinctive motivational strategies used by coaches in the two contexts. Findings have implications for the assessment of the coach-created motivational environment and the promotion of quality motivation for young athletes taking part in grass-roots-level sport.

Extensive exercise increases the plasma content of IL-6, IL-8, IL-15, leukemia inhibitory factor (LIF), and several other cytokines via their augmented transcription in skeletal muscle cells. However, the relative impact of aerobic and resistant training interventions on cytokine production remains poorly defined. In this study, we compared effects of dynamic and static load on cytokine plasma content in elite strength- and endurance-trained athletes vs. healthy untrained volunteers. The plasma cytokine content was measured before, immediately after, and 30 min post-exercise using enzyme-linked immunosorbent assay. Pedaling on a bicycle ergometer increased IL-6 and IL-8 content in the plasma of trained athletes by about 4- and 2-fold, respectively. In contrast to dynamic load, weightlifting had negligible impact on these parameters in strength exercise-trained athletes. Unlike IL-6 and IL-8, dynamic exercise had no impact on IL-15 and LIF, whereas static load increases the content of these cytokines by ~50%. Two-fold increment of IL-8 content seen in athletes subjected to dynamic exercise was absent in untrained individuals, whereas the ~50% increase in IL-15 triggered by static load in the plasma of weightlifting athletes was not registered in the control group. Thus, our results show the distinct impact of static and dynamic exercises on cytokine content in the plasma of trained athletes. They also demonstrate that both types of exercises differentially affect cytokine content in plasma of athletes and untrained persons.

Improving cognition in people with neuropsychiatric disorders remains a major clinical target. By themselves pharmacological and non-pharmacological approaches have shown only modest effects in improving cognition. In the present study we tested a recently-proposed methodology to combine CT with a 'cognitive-enhancing' drug to improve cognitive test scores and expanded on previous approaches by delivering combination drug and CT, over a long intervention of repeated sessions, and used multiple tasks to reveal the cognitive processes being enhanced. We also aimed to determine whether gains from this combination approach generalised to untrained tests. In this proof of principle randomised-controlled trial thirty-three healthy volunteers were randomised to receive either modafinil or placebo combined with daily cognitive training over two weeks. Volunteers were trained on tasks of new-language learning, working memory and verbal learning following 200 mg modafinil or placebo for ten days. Improvements in trained and untrained tasks were measured. Rate of new-language learning was significantly enhanced with modafinil, and effects were greatest over the first five sessions. Modafinil improved within-day learning rather than between-day retention. No enhancement of gains with modafinil was observed in working memory nor rate of verbal learning. Gains in all tasks were retained post drug-administration, but transfer effects to broad cognitive abilities were not seen. This study shows that combining CT with modafinil specifically elevates learning over early training sessions compared to CT with placebo and provides a proof of principle experimental paradigm for pharmacological enhancement of cognitive remediation.

Session ratings of perceived exertion (session RPE) are commonly used to assess global training intensity for team sports. However, there is little research quantifying the intensity of field-based training protocols for speed development. The study's aim was to determine the session RPE of popular training protocols (free sprint [FST], resisted sprint [RST], and plyometrics [PT]) designed to improve sprint acceleration over 10 m in team sport athletes. Twenty-seven men (age = 23.3 ± 4.7 years; mass = 84.5 ± 8.9 kg; height = 1.83 ± 0.07 m) were divided into 3 groups according to 10-m velocity. Training consisted of an incremental program featuring two 1-hour sessions per week for 6 weeks. Subjects recorded session RPE 30 minutes post training using the Borg category-ratio 10 scale. Repeated measures analysis of variance found significant (p sports conditioning program.

The purpose of this study was to clarify training-related risk factors for overuse injuries. This was twelve-month retrospective study which was done by self-reported postal questionnaire. The study group consisted of 446 men and women top-level Finnish athletes representing three different endurance sports (cross-country skiing, swimming, long-distance running) between the ages of 15-35. Self-reported anthropometric and training-related variables (such as starting age of training, years of active training, hours trained yearly, competition hours and weekly resting days) and occurrence of overuse injuries. Athletes with less than 2 rest days per week during the training season had 5.2-fold risk (95% confidence intervals [CI] 1.89-14.06, P=0.001) for an overuse injury, and athletes who trained more than 700 hours during a year had 2.1-fold risk (95% CI 1.21-3.61, P=0.008) for an overuse injury compared to the others. Athletes who reported a tendon injury were on average two years older than athletes without such an injury (Ptraining are training-related risk factors for overuse injuries in top-level endurance athletes. The higher number of tendon overuse injuries in older than younger athletes may indicate that age-related degeneration plays an important role in the etiology of tendon injuries. These findings should be taken into account when planning exercise programs for endurance athletes.
Full Text Available Competitive athletes frequently use altitude training (AT to improve sea-level performance. ATbecame interesting for sport scientists and athletes since Olympic Games in Mexico City in 1968. Exercise ataltitude may increase the training stimulus and enlarge the effects of endurance training. The first notedadaptation induced by staying at altitude is an increase in red blood cell mass that improves aerobic power andsea-level performance. Currently, there are several types of AT modalities: traditional ‘live high-train high’,contemporary ‘live high-train low’, intermittent hypoxic exposure during rest, live low-train high andintermittent hypoxic exposure during continuous session. Despite several substantial differences between thesemethods of hypoxic all of them have the same goal: to stimulate an improvement in athletic performance at sealevel. A proper distinction must be made between altitude acclimatization during preparation for competitions ataltitude and AT and acclimatization for improvement of the sea-level performances. Former scientific researchesidentified two longer phases of enhanced work capacity after AT. First phase of enhanced work capacityoccurring between days 3-7 and 12-13, while the best results are achieved during 18 and 20 days after AT.Second phase of enhanced work capacity is reported between days 36 and 48 after AT. The further developmentof practical knowledge in area of AT should predominantly include recommendations about application ofdifferent AT methods in training periodization in different sports. Improvement of the work capacity andduration of enhanced work capacity at the sea level after AT stimuli are the main questions opened for futurescientific researches.

This paper addresses practical and ethical considerations regarding genetic tests to predict performance and/or risk of exercise-related injury or illness. Various people might wish to conduct sport-related genetic tests for a variety of reasons. For example, an individual might seek personal genetic information to help guide their own sport participation. A sports coach might wish to test young athletes to aid team selection or individualize training. A physician might want to predict the risk of injury or illness in athletes and advise regarding selection or preventative measures. An insurance company might seek to estimate the risk of career-threatening injury for athletes based partly on genetic information. Whilst this information is, in part, encoded in our DNA sequence, the available tests allow generally only a poor prediction of the aforementioned variables. In other words, the current genetic tests and analysis methods are not powerful enough to inform important decisions in sport to a substantial degree. It is particularly disappointing that more than half of the commercially available genetic tests related to exercise and sport do not appear to identify publicly the genetic variants they assess, making scrutiny by academic scholars and consumers (or their representatives) impossible. There are also challenging ethical issues to consider. For example, the imposition of genetic tests on individuals (especially young people) by third parties is potentially susceptible to abuse. Scientists and practitioners should understand the limitations of the tests currently available, the ethical concerns and the importance of counselling before and after testing so that they are only used in a responsible manner. © 2016 S.

Post-industrial societies have to face the problem of physical inactivity and inappropriate lifestyles. Programs to promote physical activity are strongly supported by supranational, national and local institutions and organizations. These programs can be developed in sport facilities but also in places that are not institutionally dedicated to sport. The use of urban and working sites has the advantage of better reach the various segments of the population, but at the same time requires coordination between various professionals in structuring an effective intervention.

Several guidelines and regulations face the problem of safety in sport environments. The context is in rapid evolution and directions are provided by public health authorities. Graduates in Sport and Physical Activity, represent an additional resource in terms of: prevention and safety in the workplace, health education, application of preventive and adapted physical activities in the territory. These tasks can be integrated in all prevention stages: e.g. childhood and primary prevention programs in school, adapted physical activity for the elderly. The contribution of public health specialists is strategic in the surveillance and coordination of integrated projects. At the same time, graduates in Physical Education appear to be pivots for health promotion and qualified resources for institutions in the territory. Their training should always include contents related to prevention and safety, regulations on sport and working environments, along with bases of preventive medicine related to the context of physical activity.

Support from a doula is known to have physical and emotional benefits for mothers, but there is little evidence about the experiences of volunteer doulas. This research aimed to understand the motivation and experiences of volunteer doulas who have been trained to support women during pregnancy, birth and the postnatal period. A postal questionnaire survey was sent to volunteer doulas at five volunteer doula projects working in low-income areas in England. Quantitative and qualitative data were analysed in parallel using summary statistics and content analysis respectively. Eighty-nine volunteer doulas (response rate 34.5 %) from diverse backgrounds responded to the survey. Major motivators for volunteering included a desire to help others and, to a lesser extent, factors related to future employment. Most reported that the training was effective preparation for their role. They continued volunteering because they derived satisfaction from the doula role, and valued its social aspects. Their confidence, skills, employability and social connectedness had all increased, but many found the ending of the doula-mother relationship challenging. For a minority, negative aspects of their experience included time waiting to be allocated women to support and dissatisfaction with the way the doula service was run. Most respondents found the experience rewarding. To maintain doulas' motivation as volunteers, services should: ensure doulas can start supporting women as soon as possible after completing the training; consider the merits of more flexible endings to the support relationship; offer opportunities for ongoing mutual support with other doulas, and ensure active support from service staff for volunteers.

Data are lacking regarding the independent risk of injury related to intense single-sport training or growth rate in young athletes. To determine whether sports specialization, weekly training volumes, and growth rates are associated with increased risk for injury and serious overuse injury in young athletes. Case-control study; Level of evidence, 3. Injured athletes aged 7 to 18 years were recruited from 2 hospital-based sports medicine clinics and compared with healthy controls from affiliated primary care clinics undergoing sports physicals (2010-2013). Participants completed surveys reporting hours per week spent in organized sports, physical education class, and free play, as well as degree of sports specialization and Tanner stage. Heights and weights were measured. Injury details were obtained from athlete surveys and electronic medical records. Of 1214 athletes enrolled, 1190 (50.7% male) had data satisfactory for analysis. There were 822 injured participants (49.5% male; unique injuries, n = 846) and 368 uninjured participants (55% male). Injured athletes were older than uninjured athletes (14.1 ± 2.1 vs. 12.9 ± 2.6 years; P sports activity (11.2 ± 2.6 vs. 9.1 ± 6.3 h/wk; P sports activity spent per week, sports-specialized training was an independent risk for injury (odds ratio [OR], 1.27; 95% CI, 1.07-1.52; P sports per week than number of age in years (OR, 2.07; 95% CI, 1.40-3.05; P sports to free play time was >2:1 hours/week had increased odds of having a serious overuse injury (OR, 1.87; 95% CI, 1.26-2.76; P sports. There is an independent risk of injury and serious overuse injury in young athletes who specialize in a single sport. Growth rate was not related to injury risk. The study data provide guidance for clinicians counseling young athletes and their parents regarding injury risks associated with sports specialization. © 2015 The Author(s).

Introduction: A Canadian sports chiropractic research agenda has yet to be defined. The Delphi method can be utilized to achieve this purpose; however, the sample of experts who participate can influence the results. To better inform sample selection for future research agenda development, we set out to determine if differences in opinions about research priorities exist between chiropractors who have their sports specialty designation and those who do not. Methods: Fifteen sports clinical practice chiropractors who have their sports fellowship designation and fifteen without, were interviewed with a set of standardized questions about sports chiropractic research priorities. A centering resonance analysis and cluster analysis were conducted on the interview responses. Results: The two practitioner groups differed in their opinions about the type of research that they would like to see conducted, the research that would impact their clinical practice the most, and where they believed research was lacking. However, both groups were similar in their opinions about research collaborations. Conclusion: Sports clinical practice chiropractors, with their sports specialty designation and those without, differed in their opinions about sports chiropractic research priorities; however, they had similar opinions about research collaborations. These results suggest that it may be important to sample from both practitioner groups in future studies aimed at developing research agendas for chiropractic research in sport. PMID:28065995

Knowledge of abundance and survival of humpback whales, white-beaked dolphins and minke whales are essential to manage and conserve these species in Icelandic coastal shelf waters. Our main goal was to test the feasibility of employing inexpensive research methods (data collected by trained-scientist volunteers onboard opportunistic vessels) to assess abundance and apparent survival. No previous studies in Iceland have investigated these two demographic parameters in these three cetacean species using open capture-recapture models accounting for imperfect and possibly heterogeneous detection. A transient effect was accounted for whenever required to estimate the population of resident individuals. Identification photographs were collected by scientist-trained volunteers for 7 years (2006-2013) from onboard commercial whale-watching vessels in the coastal waters of Faxaflói (southwest coast, 4400 km2) and Skjálfandi (northeast coast, 1100 km2), Iceland. We estimated an average abundance of 83 humpback whales (Mn; 95% confidence interval: 54-130) in Skjálfandi; 238 white-beaked dolphins (La; [163-321]) in Faxaflói; and 67 minke whales (Ba; [53-82]) in Faxaflói and 24 (14-31) in Skjálfandi. We also found that apparent survival was constant for all three species (Mn: 0.52 [0.41-0.63], La: 0.79 [0.64-0.88], Ba-Faxaflói: 0.80 [0.67-0.88], Ba-Skjálfandi: 0.96 [0.60-0.99]). Our results showed inter-annual variation in abundance estimates which were small for all species, and the presence of transience for minke whales. A significant increase in abundance during the study period was solely found in minke whale data from Skjálfandi. Humpback whales and white-beaked dolphins showed lower apparent survival rates compared to similar baleen whale and dolphin populations. Our results show data collected by trained-scientist volunteers can produce viable estimates of abundance and survival although bias in the methods we employed exist and need to be addressed.

To describe the epidemiology of competition and training-based surf sport-related injury in Australia in the years 2003-2011. A retrospective epidemiological review. Information on surf sport-related injuries was obtained from Surf Life Saving Australia's SurfGuard Incident Reporting Database during 1 January 2003 to 20 August 2011. There were 2645 surf sport-related competition or training-related incidents. Males and females experienced similar proportions of injury by activity type, with older individuals experiencing a higher proportion of injuries during training than younger individuals. Minor first aid was required for 54.5% of the competition and 43.7% of the training-related incidents, with major first aid required in just over 10% of both incident types. Overall, inflatable rescue boats, beach flags, and surf boats were the most common activities performed at the time of the incident, with returning to shore and negotiating the break the most common possible contributing factors to surf boat incidents. Bruises/contusions, strains, inflammation/swelling, and sprains were the most common types of injuries that occurred during both competition and training. RICE--Rest-Ice-Compression-Elevation--was the most common form of initial treatment for the injury during both competition and training. Participation in surf sports is not without risk of injury. Information from this study will inform injury prevention efforts for surf sport and act as a guide for future research in this area, and towards improved injury surveillance for surf sport-related injuries.

Although there are many studies demonstrating a high percentage of adult athletes who start exercise in suboptimal hydration state, limited data concerning hydration levels in athletic youth exist. The purpose of this study was to identify the hydration status of elite young athletes of different sports, during a typical day of training. Fifty-nine young elite male athletes from different sports (basketball, gymnastics, swimming, running, and canoeing) participated in the study (age: 15.2 ± 1.3 years; years of training: 7.7 ± 2.0). Hydration status was assessed in the morning, before and immediately after practice. Data collection took place at the same time of the day, with mean environmental temperature and humidity at the time of the measurements at 27.6 ± 0.9° C and 58 ± 8%, respectively. All athletes trained for approximately 90 minutes, and they were consuming fluids ad libitum throughout their practice. Over 89% of the athletes were hypohydrated (urine specific gravity [USG] ≥1.020 mg·dl) based on their first morning urine sample. Pretraining urine samples revealed that 76.3% of the athletes were hypohydrated, whereas a significant high percent remained hypohydrated even after training according to USG values ≥1.020 mg·dl (74.5%) and urine color scale: 5-6 (76.3%). Mean body weight loss during training was -1.1 ± 0.07%. We concluded that the prevalence of hypohydration among elite young athletes is very high, as indicated by the USG and urine color values. The majority of the athletes was hypohydrated throughout the day and dehydrated even more during practice despite fluid availability.
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.

Despite the limited research on the effects of altitude (or hypoxic) training interventions on team-sport performance, players from all around the world engaged in these sports are now using altitude training more than ever before. In March 2013, an Altitude Training and Team Sports conference was held in Doha, Qatar, to establish a forum of research and practical insights into this rapidly growing field. A round-table meeting in which the panellists engaged in focused discussions concluded this conference. This has resulted in the present position statement, designed to highlight some key issues raised during the debates and to integrate the ideas into a shared conceptual framework. The present signposting document has been developed for use by support teams (coaches, performance scientists, physicians, strength and conditioning staff) and other professionals who have an interest in the practical application of altitude training for team sports. After more than four decades of research, there is still no consensus on the optimal strategies to elicit the best results from altitude training in a team-sport population. However, there are some recommended strategies discussed in this position statement to adopt for improving the acclimatisation process when training/competing at altitude and for potentially enhancing sea-level performance. It is our hope that this information will be intriguing, balanced and, more importantly, stimulating to the point that it promotes constructive discussion and serves as a guide for future research aimed at advancing the bourgeoning body of knowledge in the area of altitude training for team sports.

Resistance training in untrained adolescents can positively effect health-related fitness as well as improve muscular power and sports performance. The impact of resistance training on adolescent athletes is less clear. The purpose of this review is to determine the effectiveness of resistance training programs on muscular power and sports performance in adolescent athletes. Systematic review and meta-analysis of previously published studies investigating resistance training in adolescent athlete populations. A systematic search of Medline, Embase, and SPORTDiscus databases was conducted on 21st March 2011 to identify studies evaluating resistance training programs on power and sports performance in adolescent athletes. Thirty-four studies were identified. All but two of the studies reported at least one statistically significant improvement in an alactic muscular power outcome. The most common indicators of alactic power were vertical jump (25 studies) and sprint running (13 studies) performance. Fourteen studies provided data to allow for pooling of results in a meta-analysis. A positive effect was detected for resistance training programs on vertical jump performance (mean difference 3.08 [95% CI 1.65, 4.51], Z=4.23 [Ptraining interventions can improve muscular power in adolescent athletes. A positive effect on sports performance attributable to participation in resistance training was reported by almost half the included studies, however limited objective evidence to support these claims was found. Improvements in motor performance skills, such as jumping, are widely stated as indicators of improvements in sporting performance. Copyright © 2012 Sports Medicine Australia.

Adolescent student-athletes face time constraints due to athletic and scholastic commitments, resulting in habitually shortened nocturnal sleep durations. However, there is a dearth of research on the effects of sleep debt on student-athlete performance. The study aimed to (i) examine the habitual sleep patterns (actigraphy) of high-level student-athletes during a week of training and academic activities, (ii) ascertain the effects of habitual sleep durations experienced by high-level student-athletes on psychomotor performance, and (iii) examine the impact of sport training intensities on the sleep patterns of high-level student-athletes that participate in low and high intensity sports. Sleep patterns of 29 high-level student-athletes (14.7 ± 1.3 yrs) were monitored over 7 days. A psychomotor vigilance task was administered on weekdays to ascertain the effects of habitual sleep durations. Weekend total sleep time was longer than weekdays along with a delay in bedtime, and waketimes. Psychomotor vigilance reaction times on Monday were faster than on Thursday and Friday, with reaction times on Tuesday also faster than on Friday. False starts and lapses were greater on Friday compared with Monday. There was a negative impact of sleep debt on student-athletes' psychomotor performance.

To determine the 1-year self-reported incidence of overuse and traumatic sport injuries and risk factors for injuries in children participating in a summer sports camp representing seven different sports. 4363 children, 11 to 15 years old participating in a summer camp in seven different sports answered a questionnaire. Injury in this cross-sectional study was defined as a sport-related trauma or overload leading to pain and dysfunction preventing the person from participation in training or competition for at least 1 week. A number of risk factors for injury were investigated such as sex, age, number of hours spent on training in general, and on resistance training with weights. Nearly half [49%, 95% confidence interval (CI) 48-51%] of the participants had been injured as a result of participation in a sport during the preceding year, significantly more boys than girls (53%, 95% CI 50-55% vs 46%, 95% CI 43-48%; P sport injuries: age, sex, and resistance training with weights. Time spent on resistance training with weights was significantly associated with sport injuries in a logistic regression analysis. In children age 11 to 15 years, the risk of having a sport-related injury increased with age and occurred more often in boys than in girls. Weight training was the only modifiable risk factor that contributed to a significant increase in the incidence of sport injuries. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In recent years, biofeedback has become increasingly popular for its proven success in peak performance training - the psychophysiological preparation of athletes for high-stakes sport competitions, such as the Olympic games. The aim of this research was to test whether an 8-week period of exposure to biofeedback training could improve the psychophysiological control over competitive anxiety and enhance athletic performance in participating subjects. Participants of this study were highly competent athletes, each training in different sport disciplines. The experimental group consisted of 18 athletes (4 women, 14 men), whereas the Control group had 21 athletes (4 women, 17 men). All athletes were between 16 and 34 years old. The biofeedback device, Nexus 10, was used to detect and measure the psychophysiological responses of athletes. Athletes from both groups (control and experimental) were subjected to stress tests at the beginning of the study and once again at its conclusion. In between, the experimental group received training in biofeedback techniques. We then calculated the overall percentage of athletes in the experimental group compared with those in the control group who were able to control respiration, skin conductance, heart rate, blood flow amplitude, heart rate variability, and heart respiration coherence. One year following completion of the initial study, we questioned athletes from the experimental group, to determine whether they continued to use these skills and if they could detect any subsequent enhancement in their athletic performance. We demonstrated that a greater number of participants in the experimental group were able to successfully control their psychophysiological parameters, in comparison to their peers in the control group. Significant results (p biofeedback - psycho-regulation skills. Furthermore, these participants uniformly reported believing that these skills had enhanced their athletic performance and general well-being.

Full Text Available Aim: The use of external and internal load is an important aspect of monitoring systems in team sport. The aim of this study was to validate a novel measure of training load by quantifying the training-performance relationship of elite Australian footballers.Methods: The primary training measure of each of 36 players was weekly load derived from a weighted combination of Global Positioning System (GPS data and perceived wellness over a 24-week season. Smoothed loads representing an exponentially weighted rolling average were derived with decay time constants of 1.5, 2, 3, and 4 weeks. Differential loads representing rate of change in load were generated in similar fashion. Other derived measures of training included monotony, strain and acute:chronic ratio. Performance was a proprietary score derived from match performance indicators. Effects of a 1 SD within-player change below and above the mean of each training measure were quantified with a quadratic mixed model for each position (defenders, forwards, midfielders, and rucks. Effects were interpreted using standardization and magnitude-based inferences.Results: Performance was generally highest near the mean or ~1 SD below the mean of each training measure, and 1 SD increases in the following measures produced small impairments: weekly load (defenders, forwards, and midfielders; 1.5-week smoothed load (midfielders; 4-week differential load (defenders, forwards, and midfielders; and acute:chronic ratio (defenders and forwards. Effects of other measures in other positions were either trivial or unclear.Conclusion: The innovative combination of load was sensitive to performance in this elite Australian football cohort. Periods of high acute load and sustained increases in load impaired match performance. Positional differences should be taken into account for individual training prescription.

Recently, high-intensity interval training (HIIT) has received much attention as a promising exercise option not only to improve aerobic fitness, but also to prevent and improve lifestyle-related diseases. Epidemiological studies have shown that the exercise volume, as determined by the product of exercise intensity, duration, and frequency, has been shown to be important for improvements in muscle mitochondrial activity and subsequent improvements in aerobic fitness, insulin sensitivity, and metabolic variables. Therefore, continuous moderate-intensity training has been widely recommended. On the other hand, the main contributor of HIIT to improvements in aerobic fitness and metabolic variables is its high-intensity nature, and many recent studies have shown results favoring HIIT when compared with conventional continuous training, despite its shorter exercise duration and smaller exercise volume. In this review, we aim to show the possible universal application of HIIT in a hospital setting, where athletes, sports lovers, and patients have sought medical advice and have the opportunity to undergo detailed evaluations, including an exercise stress test. For athletes, HIIT is mandatory to achieve further improvements in aerobic fitness. For patients, though higher levels of motivation and careful evaluation are required, the time constraints of HIIT are smaller and both aerobic and resistance training can be expected to yield favorable results because of the high-intensity nature of HIIT.

Use of Web-based data recording systems has received little attention in sport. An "online" training diary could provide a valuable alternative to pen-paper methods in the regular assessment of physical activity and illness occurrence in athletes. The objective of this study was to design and implement a user-friendly and efficient system to monitor incidences of illness in team sport athletes. Prospective monitoring study over a 48-week rugby season. Players were asked to register presence/absence of weekly illness symptoms with medical staff and also use an online training diary. Submitted self-reported diary illness data were compared with illness complaint data recorded by medical staff. Diary response rates were calculated from the number of completed diary entries against the number of available/required entries over the season. Web-based training diary. Thirty professional rugby union players. Comparison of gastrointestinal and upper respiratory illnesses (URIs) reported by players using an online diary and to medical staff. Incidences of URIs. The diary response rate in the reporting of weekly illnesses was 79% over the study period. Discrepancy existed between the number of self-reported URIs by players using the diary (118 URI incidences) compared with those reported to medical staff (23 URI incidences). Totaling all URI episodes (those self-reported + those registered by medical staff) revealed that players reported just 19% of URI episodes to medical staff. Players tend to underreport incidences of banal infections. Closer monitoring of self-reported illnesses using a similar system in the present study may provide a better alternative to previous methods in nonclinical illness assessment.

Full Text Available ABSTRACT This study aimed to provide baseline data for the serum biochemical parameters of Brazilian sport horses undergoing physical training for eventing to be used as a practical guide. A total of 139 blood samples were collected by vacuum venipuncture of the jugular vein from healthy horses in training. Tubes without anticoagulant were used for biochemical analysis. Means and standard deviations were determined for aspartate aminotransferase (AST (306.27±84.66 U/L, creatine kinase (CK (181.06±80.38 U/L, urea (29.51±5.82 mg/dL, creatinine (1.44±0.20 mg/dL, gamma glutamyl transferase (GGT (14.58±6.55 U/L, calcium (13.22±0.59 mg/dL, and albumin (2.86±0.16 g/dL. The specific reference ranges were: AST, 197-454 U/L; CK, 116-290 U/L; urea, 22-42 mg/dL; creatinine, 1.2-1.8 mg/dL; GGT, 9-26 U/L; calcium, 12.2-14.2 mg/dL; and albumin, 2.6-3.1 g/dL. Beneficial effects of the training program on the horses were observed and these effects did not lead to any changes in the biochemical parameters studied. The environment may influence the serum biochemical parameters, particularly AST and CK, of Brazilian sport horses.

The Indonesian Ministry of Health relies on a network of over a million kader (community health volunteers) to bring primary health care to the village level. In West Java, the Department of Health's Control of Diarrhoeal Disease (CDD) Program recently carried out an extensive research and development effort to produce effective job aids for the kader in CDD and a training programme to teach their use. A set of counselling cards was produced to provide kader with a tool to diagnose and treat diarrhoea and teach the proper use of ORS. Researchers conducted a controlled evaluation in which they measured the cards' effectiveness through observations of kader performance and interviews with mothers they had counselled. In the intervention group, 15 kader underwent two days training in the use of the cards when diagnosing and advising treatment for cases of diarrhoea in their villages. The 16 control kader received comparable CDD training without the cards. Each group provided lists of local mothers they pledged to counsel during the coming weeks. Follow-up interviews were held with these mothers to test their level of knowledge on CDD and to observe their ability to mix ORS properly. Significant performance differences between the intervention kader and mothers, and the control kader and mothers, were demonstrated. The intervention kader were consistently more accurate in their diagnoses and recommendations for treatment with a mean of 83% accuracy vs 68% for the control kader. Mothers counselled by the intervention kader also prepared ORS significantly better than the mothers counselled by the control kader, with 97 vs 74% accuracy.

Regular participation in organized youth sports does not ensure adequate exposure to skill- and health-related fitness activities, and sport training without preparatory conditioning does not appear to reduce risk of injury in young athletes. Current trends indicate that widespread participation in organized youth sports is occurring at a younger age, especially in girls. Current public health recommendations developed to promote muscle strengthening and bone building activities for youth aged 6 yr and older, along with increased involvement in competitive sport activities at younger ages, has increased interest and concern from parents, clinicians, coaches, and teachers regarding the optimal age to encourage and integrate more specialized physical training into youth development programs. This review synthesizes the latest literature and expert opinion regarding when to initiate neuromuscular conditioning in youth and presents a how-to integrative training conceptual model that could maximize the potential health-related benefits for children by reducing sports-related injury risk and encouraging lifelong, regular physical activity.

To document neuromuscular training (NMT) availability and its relationship to anterior cruciate ligament (ACL) injuries in 4 major high school sports by gender, sport, and rural/urban geography, with the hypothesis that increased exposure to NMT would be associated with fewer ACL injuries. A retrospective cohort study. All Minnesota high schools identified in the Minnesota State High School League (MSHSL) database for fall 2014 boys' football and soccer, and girls' volleyball and soccer. All high school athletic directors were surveyed to report their school's fall 2014 experience; 53.5% returned the survey reporting experience with one or more of the sports. Athletic directors documented each sport's preseason and in-season exposure to NMT (plyometric exercises, proximal/core muscle strengthening, education and feedback regarding proper body mechanics, and aerobics) and licensed athletic trainers. Reported ACL injuries by sport, gender and rural/urban. More than two-thirds of teams incorporated facets of NMT into their sport. Among male athletes, soccer players exposed to licensed athletic trainers experienced significantly fewer ACL injuries (P < 0.005), and NMT was associated with significantly fewer ACL injuries in football (P < 0.05) and soccer (P < 0.05). Female athletes did not demonstrate similar associated improvements, with volleyball injuries associated with increased NMT (P < 0.001), and soccer injuries not associated with NMT. However, girl soccer players in rural settings reported fewer ACL injures compared with urban teams (P < 0.001). Most fall high school sports teams were exposed to NMT, which was associated with fewer ACL injuries for male, but not for female athletes. Improved gender- and sport-specific preventive training programs are indicated.

Many young people look forward to volunteering abroad and overlook the ample volunteer opportunities at home. There are several advantages to volunteering at home: you help people in your own community; you can make a long-term commitment; and you have continuity of care for your patients. There are >1200 free clinics in the United States whose main goal is to provide care to the indigent population. These free clinics are always looking for volunteers with specialized medical training. This article reviews the medically related and unrelated volunteer opportunities available in the United States. Volunteering at home is a worthwhile experience, and I encourage the otolaryngology community to explore these opportunities. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

In the wake of recent wars, some military personnel face considerable physical and mental health problems. In this article I explore the effects of an adapted sport and inclusive adventurous training course for military personnel who have experienced physical injury and/or psychological trauma. Using a dialogical narrative approach, I analyzed stories shared by six soldiers during the course to explore the effects of involvement. Participation in the course seemed to facilitate a narrative transformation or opening corresponding to a broadening identity and sense of self. Story plots progressed from a failing monological narrative, through a chaos narrative, toward a dialogical quest narrative prioritizing immersion in an intense present, a developing self, and a relational orientation. On the basis of narrative theory, I suggest this transformation holds positive consequences for the health and well-being of military personnel who have experienced injury and/or trauma. © The Author(s) 2014.

Cervical cancer is known as one of the most prevalent types of cancers and a major public health problem in developing countries which can be detected by Pap test, prevented, and treated. Despite the effective role of Pap test in decreasing the incidence and mortality due to cervical cancer, it is still one the most common causes of cancer-related deaths among women, especially in developing countries. Thus, this study aimed to examine the effect of educational interventions implemented by health volunteers based on protection motivation theory (PMT) on promoting Pap test use among women. This quasi-experimental study was conducted on 60 health volunteers and 420 women. The study participants were divided into an intervention and a control group. Data were collected using a valid self-reported questionnaire including demographic variables and PMT constructs which was completed by both groups before and 2 months after the intervention. Then, the data were entered into the SPSS statistical software, version 19 and were analyzed using Chi-square test, independent T-test, and descriptive statistical methods. PPap test use also increased by about 62.9% among the study women. This study showed a significant positive relationship between PMT-based training and Pap test use. The results also revealed the successful contribution of health volunteers to training cervical cancer screening. Thus, training interventions based on PMT are suggested to be designed and implemented and health volunteers are recommended to be employed for educational purposes and promoting the community's, especially women's, health.

Introduction: Psychological distress is among physical and mental health threats, and health volunteers can play a critical role in empowerment of women. However, evidence has revealed a decline in health volunteers’ activities. Therefore, the present study aimed to investigate the challenges faced by health volunteers in empowerment of women. Methods: The participants’ knowledge level was assessed using a written test. Their perceived skills were also measured using Coping Inventory for Stressful Situations by Endler and Parker and Chesney’s Coping Self-efficacy Scale, respectively. The study data were entered into the SPSS statistical software, version 11.5 and were analyzed using chi-square, sample t-test, and Pearson’s correlation coefficient. Results: The results showed a considerable increase in the intervention group health volunteers’ knowledge about stress, as well as their self-efficacy. Besides, a significant correlation was observed between self-efficacy and task-oriented strategy scores. However, no significant increase was found in this group’s coping strategies. The results also indicated a significant increase in the intervention group women’s knowledge about stress, but no significant change was observed in other constructs. Some challenging factors, such as managerial, personal, and interpersonal factors, were also detected that might have affected the results. Discussion: This study caused no considerable change in coping with stress, except for increasing the women’s knowledge in this regard. Considering the challenges identified in this study, programs should be developed for researchers and health center managers to improve this condition in future. Creative Commons Attribution License

Full Text Available The modern sports movement is going through a process of differentiation. New activities have developed and are still developing. New values and new organizational forms and methods of sports training can replace older ones. Sport is a part of modern lifestyle and various subcultures show the diversity of modern sport. In this paper we try to introduce some experiences about the new philosophy of changing values in modern society and try to give a description of process of value differentiation in sport. We used the methods, methodological principles and means of experienced learning through the pedagogical experiment (special training camps that were a part of long time preparation of some groups of young athletes in Wild water slalom. The used programmes (icebreakers, contact games, trust games, initiative and team games, strategic games, social and dramatic games, communication and cooperation games, environmental games, overcoming obstacles, rope courses….. were firstly opportunities for self-development as well as for learning a great deal about teamwork. There are not exact quantitative results but our experiences show a considerable qualitative development in cohesion of the whole team and positive communication among team and coaches. The success of the Czech team at Junior World and European Championships probably reflects the personal development (selfconfidence, self-respect, self-fulfilment, high spirit of competitors.

The aim of this short review was to summarize data pertaining to the rating of perceived exertion (RPE) methods (RPE value and session-RPE) during combat sport-specific activities (i.e., competition and training) based on many factors, including contest type (i.e., official vs. simulated vs. training), combat rounds, age of participants and muscle groups, and their correlation with physiological variables (i.e., blood lactate concentration [La] and heart rate [HR]). The current review shows higher RPE in a match of mixed martial arts (MMAs) than Brazilian jiu-jitsu and kickboxing matches and during the competitive period compared with the precompetitive period. This could be explained by the longer duration of bouts, the higher percentage contribution of aerobic metabolism in MMA than other combat sports and contest type differences (simulated vs. official matches). Thus, this review found significant correlations between RPE or session-RPE, [La] and HR. Particularly, there was a stronger correlation between RPE and [La] during official striking (r = 0.81) than grappling combat sports matches (r = 0.53). In addition, a variation of correlation (moderate to large) between session-RPE and HR-based methods has been reported (i.e., Edwards' training load [r ranged between 0.58 and 0.95] and Banister training impulse [r ranged between 0.52 and 0.86]). Specifically, stronger correlation was apparent in combat sport competition that required a much higher percentage contribution of aerobic metabolism (e.g., karate) and in adult athletes than anaerobic-based combat sports (e.g., taekwondo) and young athletes, respectively. Indeed, the current review highlights that the correlations between session-RPE and HR-based methods were higher during official competition than training sessions. Session-RPE was affected by participants' competitive level, the intensity of session (high vs. low), the training modalities (tactical-technical vs. technical-development vs. simulated

Full Text Available The purpose of the study was to determine the efficacy of a 22- week prescribed sports specific balance training programme on the incidence of lateral ankle sprains in basketball players. A controlled clinical trial was set up. In total 54 subjects of six teams participated and were assigned to either an intervention (IG or a control group (CG. The IG performed a prescribed balance training programme on top of their normal training routine, using balance semi-globes. The programme consisted of 4 basketball skills each session and its difficulty was progressively thought-out. The intervention lasted 22 weeks and was performed 3 times a week for 5 to 10 minutes. Efficacy of the intervention on the incidence of lateral ankle sprains was determined by calculating Relative Risks (RR, including their 95% Confidence Intervals or CI and incidence rates expressed per 1000h. RR (95% CI showed a significantly lower incidence of lateral ankle sprains in the IG compared to the CG for the total sample (RR= 0.30 [95% CI: 0.11-0.84] and in men (RR= 0.29 [95% CI: 0.09-0.93]. The difference in RR was not confirmed when examining the incidence rates and their 95%CI's, which overlapped. The risk for new or recurrent ankle sprains was slightly lower in the IG (new: RR= 0.76 [95% CI: 0.17-3.40]; re-injury: RR= 0.21 [95% CI: 0.03-1.44]. Based on these pilot results, the use of balance training is recommended as a routine during basketball activities for the prevention of ankle sprains

Healthy female college going students (N=186, sportswomen, 90; controls 96) in the age group of 18-21 yr, residing in New Delhi (India) were evaluated for anthropometry, biochemistry (serum total and ionic calcium, phosphorus, total alkaline phosphatase, 25-hydroxyvitamin D & parathyroid hormone), diet, physical activity and lifestyle. Bone mineral density (BMD) at hip, forearm and lumbar spine were studied using central DXA. Sports related physical activity (3 vs. 0 h/day, P direct sunlight exposure (120 vs. 30 min/day, P < 0.001) were significantly higher in sportswomen than in controls with sedentary lifestyle. Significantly higher intake of all macronutrients (energy, protein, carbohydrates and fat) and dietary calcium was noted in the diets of sportswomen. Mean serum 25(OH)D levels were significantly higher (53.0 ± 18.9 vs. 12.9 ± 7.7 nmol/l; P < 0.001) while PTH (35.3 ± 17.6 vs. 51.7 ± 44.9 pg/ml; P < 0.001) and ALP levels (194.0 ± 51.0 vs. 222.1 ± 51.4 IU/l; P<0.001) were significantly lower in sportswomen when compared to controls. No significant difference was found in ionized calcium and inorganic phosphorus in the two groups. Significantly higher (P < 0.001) total BMD and BMD at all sites except femur neck were found in sportswomen than controls (P < 0.001). Physical activity, optimal nutrition and adequate sun exposure are vital for attaining peak bone mass.

There is a need for easy-to-use methods to assess training progress in sports and rehabilitation research. The present review investigated whether cardiac acceleration at the onset of physical exercise (HRonset) can be used as a monitoring variable. The digital databases of Scopus and PubMed were searched to retrieve studies investigating HRonset. In total 652 studies were retrieved. These articles were then classified as having emphasis on HRonset in a sports or rehabilitation setting, which resulted in 8 of 112 studies with a sports application and 6 of 68 studies with a rehabilitation application that met inclusion criteria. Two co-existing mechanisms underlie HRonset: feedforward (central command) and feedback (mechanoreflex, metaboreflex, baroreflex) control. A number of studies investigated HRonset during the first few seconds of exercise (HRonsetshort), in which central command and the mechanoreflex determine vagal withdrawal, the major mechanism by which heart rate (HR) increases. In subsequent sports and rehabilitation studies, interest focused on HRonset during dynamic exercise over a longer period of time (HRonsetlong). Central command, mechanoreflexes, baroreflexes, and possibly metaboreflexes contribute to HRonset during the first seconds and minutes of exercise, which in turn leads to further vagal withdrawal and an increase in sympathetic activity. HRonset has been described as the increase in HR compared with resting state (delta HR) or by exponential modeling, with measurement intervals ranging from 0-4 s up to 2 min. Delta HR was used to evaluate HRonsetshort over the first 4 s of exercise, as well as for analyzing HRonsetlong. In exponential modeling, the HR response to dynamic exercise is biphasic, consisting of fast (parasympathetic, 0-10 s) and slow (sympathetic, 1-4 min) components. Although available studies differed largely in measurement protocols, cross-sectional and longitudinal training studies showed that studies analyzing HRonset

In the process of medical rehabilitation muscular endurance training is the main focus. Unfortunately, outpatient rehabilitation opportunities are limited and specialized pulmonary exercise groups ("lung sport groups") rarely available. Therefore we developed an outpatient endurance sports program for patients with respiratory diseases and evaluated its effectiveness. In this feasibility study 31 patients (50 ± 15 years) with diverse respiratory diseases were included. By professional functional exercise testing (incl. CPET and lactate measurement according to the standards of DGP and DGSP) the patients optimal training zone was determined and an individualized 12 week lasting aerobic endurance training with ≥ 3 sessions of 20 - 60 min/week realized. After completion of the exercise training program a significant improvement in dyspnoea (Borg-Scale: 65.7 ± 12.2 vs. 62.2 ± 12.6, p = 0.013), body constitution (BMI: 25.7 ± 3.3 vs. 24.3 ± 3.2 kg/m(2), p = 0.018; portion of body fat: 24.8 ± 5.8 vs. 23.8 ± 6.4 %, p = 0.043) as well as physical capacity (VO2 at 4 mmol/l Laktat: 24.2 ± 6.9 vs. 26.5 ± 7.6 ml/min/kg, p mental and physical quality of life (quality of life questionnaire SF-36: physical score + 9.7 points, mental score + 4.5 points). The evaluated exercise program can easily be trained by the patient in a self-dependent setting and was seen to be an effective sports medical treatment in patients with diverse pulmonary diseases. © Georg Thieme Verlag KG Stuttgart · New York.

Purpose To examine the subjective perception of daily acute fasting on sports performance, training, sleep and dietary patterns of Muslim athletes during the Ramadan month. Methods Seven hundred and thirty-four (411 male and 323 female) Malaysian Junior-level Muslim athletes (mean age 16.3 ± 2.6 y) participated in the survey which was designed to establish the personal perception of their sport performance, sleep pattern, food and fluid intake during Ramadan fasting. The survey was conducted during and immediately after the month of Ramadan in 2009. Results Twenty-four percent of the athletes perceived that there was an adverse effect of the Ramadan fast on their sporting performance and 29.3% reported that quality of training during Ramadan was also negatively influenced. Majority (48.2%) of the athletes stated that Ramadan fasting did not affect their normal sleep pattern but 66.6% of them complained of sleepiness during the daytime. Half of the athletes (41.4%) maintained the caloric intake during Ramadan as they normally would with the majority of them (76.2%) reporting that they consumed more fluids during Ramadan. Conclusions Overall, Malaysian Junior-level Muslim athletes showed diverse views in their perception of changes in their training, sleep and dietary patterns during Ramadan fast. These individual differences probably indicate differences in the athletes’ adaptability and coping strategies during fasting and training in Ramadan. PMID:22375236

Newton's second law of motion describes the acceleration of an object as being directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to its mass (a = F/m). With respect to linear motion, mass is also a numerical representation of an object's inertia, or its resistance to change in its state of motion and directly proportional to the magnitude of an object's momentum at any given velocity. To change an object's momentum, thereby increasing or decreasing its velocity, a proportional impulse must be generated. All motion is governed by these relationships, independent of the exercise being performed or the movement type being used; however, the degree to which this governance affects the associated kinematics, kinetics and muscle activity is dependent on the resistance type. Researchers have suggested that to facilitate the greatest improvements to athletic performance, the resistance-training programme employed by an athlete must be adapted to meet the specific demands of their sport. Therefore, it is conceivable that one mechanical stimulus, or resistance type, may not be appropriate for all applications. Although an excellent means of increasing maximal strength and the rate of force development, free-weight or mass-based training may not be the most conducive means to elicit velocity-specific adaptations. Attempts have been made to combat the inherent flaws of free weights, via accommodating and variable resistance-training devices; however, such approaches are not without problems that are specific to their mechanics. More recently, pneumatic-resistance devices (variable) have been introduced as a mechanical stimulus whereby the body mass of the athlete represents the only inertia that must be overcome to initiate movement, thus potentially affording the opportunity to develop velocity-specific power. However, there is no empirical evidence to support such a contention. Future research should

This internal instability is often observed by researchers investigating circadian rhythms (hormone secretion, temporal series (heart rate and behavior (hunger and satiety, who argue in favor of substituting the theory of homeostasis by the concept of allostasis (allo = different; stasis = stable. Indeed, these researchers suggest that the objective of regulation and control is not stability. There are two consequences for Physical Education and Sport if allostasis is accepted as a physiological paradigm: 1. Selye’s concept of stress requires a new defi nition and interpretation, with a clear impact on the concept of load and overload; 2. Noakes’ central governor hypothesis to explain the fatigue resulting from intense physical exercise loses its relevance, as will be discussed in this paper. Furthermore, it is very diffi cult for the model of stability by staying the same to explain why performance is improved by physical training or why we have a predisposition for this type of recognizedly anti-homeostatic activity. We intend to demonstrate the possibility that the allostatic concept of stability through change can explain these contradictions.

This study compared the use of sand and grass training surfaces throughout an 8-week conditioning programme in well-trained female team sport athletes (n = 24). Performance testing was conducted pre- and post-training and included measures of leg strength and balance, vertical jump, agility, 20 m speed, repeat speed (8 × 20 m every 20 s), as well as running economy and maximal oxygen consumption (VO2max). Heart rate (HR), training load (rating of perceived exertion (RPE) × duration), movement patterns and perceptual measures were monitored throughout each training session. Participants completed 2 × 1 h conditioning sessions per week on sand (SAND) or grass (GRASS) surfaces, incorporating interval training, sprint and agility drills, and small-sided games. Results showed a significantly higher (P < 0.05) HR and training load in the SAND versus GRASS group throughout each week of training, plus some moderate effect sizes to suggest lower perceptual ratings of soreness and fatigue on SAND. Significantly greater (P < 0.05) improvements in VO2max were measured for SAND compared to GRASS. These results suggest that substituting sand for grass training surfaces throughout an 8-week conditioning programme can significantly increase the relative exercise intensity and training load, subsequently leading to superior improvements in aerobic fitness.
Full Text Available An investigation of factors that facilitate the utilization of research evidence among faculty, staff, and volunteers in the 4-H Youth Development Program is presented in this paper. Participants (N= 368; 86 4-H faculty, 153 staff, and 129 volunteers represented 35 states; structural equation modeling was utilized in the analyses. Results of the path analysis explained 56% of variance in research utilization and 28% in research utilization self-efficacy. Among the factors impacting research utilization, self-efficacy played the most important role. In turn, self-efficacy for research utilization was positively influenced by participants’ learning goal orientation, frequency of 4-H training during the last 12 months, education in research-related areas, and investigative career interests. In addition, 4-H staff who were exposed to research at higher levels reported higher research utilization self-efficacy. The findings reinforce the importance of fostering research utilization self-efficacy among 4-H faculty, staff, and volunteers. Among the suggestions presented are regular 4-H training opportunities and on-going exposure to program evaluation and program improvement experiences.

White cell counts at rest might be lower in athletes participating in selected endurance-type sports. Here, we analysed blood tests of elite athletes collected over a 10-year period. Reference ranges were established for 14 female and 14 male sports involving 3,679 samples from 937 females and 4,654 samples from 1,310 males. Total white blood cell counts and counts of neutrophils, lymphocytes and monocytes were quantified. Each sport was scaled (1-5) for its perceived metabolic stress (aerobic-anaerobic) and mechanical stress (concentric-eccentric) by 13 sports physiologists. Substantially lower total white cell and neutrophil counts were observed in aerobic sports of cycling and triathlon (~16% of test results below the normal reference range) compared with team or skill-based sports such as water polo, cricket and volleyball. Mechanical stress of sports had less effect on the distribution of cell counts. The lower white cell counts in athletes in aerobic sports probably represent an adaptive response, not underlying pathology.

During congested fixture periods in team sports, limited recovery time and increased travel hinder the implementation of many recovery strategies; thus alternative methods are required. We examined the impact of a neuromuscular electrical stimulation device on 24-h recovery from an intensive training session in professional players. Twenty-eight professional rugby and football academy players completed this randomised and counter-balanced study, on 2 occasions, separated by 7 days. After baseline perceived soreness, blood (lactate and creatine kinase) and saliva (testosterone and cortisol) samples were collected, players completed a standardised warm-up and baseline countermovement jumps (jump height). Players then completed 60 m × 50 m maximal sprints, with 5 min recovery between efforts. After completing the sprint session, players wore a neuromuscular electrical stimulation device or remained in normal attire (CON) for 8 h. All measures were repeated immediately, 2 and 24-h post-sprint. Player jump height was reduced from baseline at all time points under both conditions; however, at 24-h neuromuscular electrical stimulation was significantly more recovered (mean±SD; neuromuscular electrical stimulation -3.2±3.2 vs. CON -7.2±3.7%; P0.05). Neuromuscular electrical stimulation improves recovery from intensive training in professional team sports players. This strategy offers an easily applied recovery strategy which may have particular application during sleep and travel. Copyright © 2014 Sports Medicine Australia. Published by Elsevier Ltd.

J Strength Cond Res 30(7): 1834-1842, 2016-Volleyball and basketball players can be considered as a population at risk for patellar tendinopathy. Given the paradox that eccentric training elicits therapeutic benefits yet might provoke such injury, we investigated the influence of a weekly bout of inertial squat resistance exercise offering eccentric overload on lower limb muscle power and patellar tendon complaints. Players of 8 (4 basketball and 4 volleyball) teams (38 women and 43 men) were randomly assigned to either the intervention (IG) or control (CG) group. Although IG and CG maintained scheduled in-season training routines over 24 weeks, IG, in addition, performed 1 weekly session of eccentric overload by 4 sets of 8 repetitions of the squat using flywheel inertial resistance. Victorian Institute of Sports Assessment patellar tendinopathy questionnaire (VISA-p), vertical countermovement jump, and squat power, both concentric (Squat-Con) and eccentric (Squat-Ecc), tests were performed before (T1), during (T2), and after (T3) the 24 weeks of intervention. Neither group suffered from patellar tendinopathy during the study period. VISA-p displayed no differences across groups at any measurement period. Countermovement jump scores significantly (p ≤ 0.05) differed between groups in favor of the IG. Both Squat-Con and Squat-Ecc mean scores from the IG were significantly (p training bout to a regular basketball and volleyball exercise routine enhances lower limb muscle power without triggering patellar tendon complaints. Future studies, using the current exercise paradigm, aim to explore its efficacy to prevent or combat patellar tendinopathy in sports calling for frequent explosive jumps.

Family carers are crucial in enabling dying people to stay at home, but are often not prepared for their caring role, receiving little support from formal health and social care services. It is increasingly likely that any help or support family carers receive will be provided by a third sector organisation on either a voluntary basis or by untrained carer support workers. To produce a training programme designed to equip carer support workers and volunteers with the basic skills and knowledge needed to support family carers. Participatory action research, a collaborative form of working in which those who are affected by an issue take a lead role in the research, was used. Bereaved carers acting as research partners, support workers and representatives of third sector organisations took an active part in designing, developing, piloting and refining the programme in a number of interlinked stages. During development, the programme was piloted on four occasions and evaluated by 36 trainees and 3 trainers. The outcome of the project is an innovative, 1-day training programme, offering an introduction to supporting family carers who are looking after someone approaching the end of life. The use of participatory action research methods enabled the development of a programme that addresses support needs identified by bereaved carers and training needs identified by carer support workers.The finished programme includes all the materials necessary to run a training day for support workers and volunteers: facilitator's notes, trainee workbook, slides, promotional poster and pre-course reading for trainees. Knowledge of issues involved in end-of-life and palliative care is not required, although some experience in delivering training is advisable. The programme evaluated well during development, but further research is required to examine the transfer of learning into the workplace. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

This partnership has contributed to the creation of the research line ‘Physical Education, Sport and Education for Peace: conceptual, methodological and teacher training dimensions’ in Gepefe. The goal of this article is to present more specific ideas for a convergence between the educational perspectives in sport and school physical education, mediated by the issue of teacher training. When considering aspects present in the discussion on the education for peace (coexistence, conflict, violence and peace, we find specifics to consider actions in teacher training. This process emerges as Brazil is experiencing a special moment in sports, with international events planned for the coming years, thereby expanding the need for thematic reflections regarding violence and coexistence in sports. This leads to reflections on the fundamental role of sports education in forming values of coexistence and debating teacher training in physical education for that reality.

Creating a healing and healthy environment for patients, families, and staff is an ongoing challenge. As part of our hospital's Integrative Care Program, a Reiki Volunteer Program has helped to foster a caring and healing environment, providing a means for patients, family, and staff to reduce pain and anxiety and improve their ability to relax and be present. Because direct care providers manage multiple and competing needs at any given time, they may not be available to provide Reiki when it is needed. This program demonstrates that a volunteer-based program can successfully support nurses in meeting patient, family, and staff demand for Reiki services.

Context: There is increased growth in sports participation across the globe. Sports specialization patterns, which include year-round training, participation on multiple teams of the same sport, and focused participation in a single sport at a young age, are at high levels. The need for this type of early specialized training in young athletes is currently under debate. Evidence Acquisition: Nonsystematic review. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Sports specialization is defined as year-round training (greater than 8 months per year), choosing a single main sport, and/or quitting all other sports to focus on 1 sport. Specialized training in young athletes has risks of injury and burnout, while the degree of specialization is positively correlated with increased serious overuse injury risk. Risk factors for injury in young athletes who specialize in a single sport include year-round single-sport training, participation in more competition, decreased age-appropriate play, and involvement in individual sports that require the early development of technical skills. Adults involved in instruction of youth sports may also put young athletes at risk for injury by encouraging increased intensity in organized practices and competition rather than self-directed unstructured free play.

Canuck Place Children's Hospice (CPCH) is regarded as one of the leading pediatric palliative care systems in the world. Since 1995, it has been providing hospice care free of charge to children and their families living with life-threatening conditions. The pediatric palliative hospice is a relatively new practice in health care, in comparison to the longstanding adult model. As a result, development and implementation of volunteer programs in pediatric hospices is not currently represented in literature. With over 300 volunteers at present, CPCH has built a successful program that can serve as a model in pediatric volunteer services. To present the unique volunteer roles and experience at CPCH, and share ways volunteers work to support the efforts of the clinical team. Strategies to address current challenges in the volunteer program are also addressed. Descriptive design. A current CPCH volunteer discusses the volunteer program. Interviews were conducted with the founding volunteer director of CPCH and current volunteers. The volunteer program at CPCH fully embraces the life of each child and family. Volunteer selection is the groundwork for ensuring a cohesive work force, while training equips volunteers with the knowledge to carry out their role with confidence. Areas of improvement that have been recognized include offering effective feedback to volunteers and delivering adequate level of training for non-direct care roles. The talents of volunteers at CPCH are diverse, and CPCH aims to recognize and thank volunteers for their continuous contributions.

The effects of a short, high-intensity bout of exercise on cardiac systolic and diastolic function are not well understood in adolescent athletes. Consequently, the aims of the study were to evaluate global left ventricular (LV) systolic and diastolic function, as well as segmental wall motion responses (cardiac strain), prior to as well as 45 and 225 min following a simulated 5 km cross-country race. Twenty trained, adolescent males (age: 15.2 ± 0.7 years) volunteered for exercise testing. LV fractional shortening and the ratio of early (E) and late (A) peak flow velocities reflected global systolic and diastolic function, respectively. Peak longitudinal mitral annular septal tissue velocities were also determined during systole and diastole. Longitudinal strain (ε) and strain rates were determined across the LV. LV fractional shortening was significantly (P global or regional LV systolic and diastolic function in trained adolescents.

High-intensity interval training improves endurance and performance, but it is unclear whether sprint-type upper-body interval training is similarly effective. This study explored the effects of 4-week sport-specific sprint interval training on punch characteristics and endurance capacity in boxers. Experienced male amateur boxers (n = 18) participated in this 4-week training study, and were divided into an experimental group (EG) and a control group (CG) (n = 9 per group). Both groups completed standard low-intensity training. The EG also completed 3 rounds (14 sets of 3 s all-out punching with 10 s rest) of a simulated fight using a punching bag with 1 min rest between rounds 3 times per week, while the CG performed the same 3 rounds of a simulated fight at low intensity. Three rounds of 14 sets of 3 s all-out punching of a bag ergometer with 10 s rest were performed to measure punching abilities. Peak oxygen consumption and peak power were measured during progressive arm cranking before and after training. In response to training peak oxygen consumption and peak power in arm cranking test increased in EG; also, punching force increased and maintenance of punching frequency and punch force improved during the simulated fight, which resulted in greater cumulative force throughout the 3 rounds. There were no changes in the CG. The study shows that 1 month of all-out punching training (3 sessions per week with ∼2 min of all-out punching per session) improved both upper-body aerobic power and punching abilities in experienced amateur boxers.

Mirror training therapy is a promising tool to initiate neural plasticity and facilitate the recovery process of motor skills after diseases such as stroke or hemiparesis by improving the intermanual transfer of fine motor skills in healthy people as well as in patients. This study evaluated whether these augmented performance improvements by mirror visual feedback (MVF) could be used for learning a sport-specific skill and if the effects are modulated by skill level. A sample of 39 young, healthy, and experienced basketball and handball players and 41 novices performed a stationary basketball dribble task at a mirror box in a standing position and received either MVF or direct feedback. After four training days using only the right hand, performance of both hands improved from pre- to posttest measurements. Only the left hand (untrained) performance of the experienced participants receiving MVF was more pronounced than for the control group. This indicates that intermanual motor transfer can be improved by MVF in a sport-specific task. However, this effect cannot be generalized to motor learning per se since it is modulated by individuals' skill level, a factor that might be considered in mirror therapy research.

There have been considerable advances in monitoring training load in running-based team sports in recent years. Novel technologies nowadays offer ample opportunities to continuously monitor the activities of a player. These activities lead to internal biochemical stresses on the various physiological subsystems; however, they also cause internal mechanical stresses on the various musculoskeletal tissues. Based on the amount and periodization of these stresses, the subsystems and tissues adapt. Therefore, by monitoring external loads, one hopes to estimate internal loads to predict adaptation, through understanding the load-adaptation pathways. We propose a new theoretical framework in which physiological and biomechanical load-adaptation pathways are considered separately, shedding new light on some of the previously published evidence. We hope that it can help the various practitioners in this field (trainers, coaches, medical staff, sport scientists) to align their thoughts when considering the value of monitoring load, and that it can help researchers design experiments that can better rationalize training-load monitoring for improving performance while preventing injury.
Full Text Available Mirror training therapy is a promising tool to initiate neural plasticity and facilitate the recovery process of motor skills after diseases such as stroke or hemiparesis by improving the intermanual transfer of fine motor skills in healthy people as well as in patients. This study evaluated whether these augmented performance improvements by mirror visual feedback (MVF could be used for learning a sport-specific skill and if the effects are modulated by skill level. A sample of 39 young, healthy, and experienced basketball and handball players and 41 novices performed a stationary basketball dribble task at a mirror box in a standing position and received either MVF or direct feedback. After four training days using only the right hand, performance of both hands improved from pre- to posttest measurements. Only the left hand (untrained performance of the experienced participants receiving MVF was more pronounced than for the control group. This indicates that intermanual motor transfer can be improved by MVF in a sport-specific task. However, this effect cannot be generalized to motor learning per se since it is modulated by individuals’ skill level, a factor that might be considered in mirror therapy research.

The aim of this study was to examine the effects of a home-based and volunteer-administered physical training and nutritional intervention program compared with social support intervention on nutritional and frailty status in prefrail and frail community-dwelling older persons. This was a randomized controlled trial in which community-dwelling persons (mean age = 83 years) were recruited and randomly assigned to the physical training and nutritional intervention group (PTN, n = 39) and the social support group (SoSu, n = 41). The study was conducted by trained lay nonprofessionals. The community-dwelling older persons in both groups were visited twice a week by trained nonprofessional volunteers (buddies) in Vienna, Austria. Eighty prefrail and frail adults aged 65 years or older. In the PTN group, both the buddies and older persons performed 6 strength exercises within a circuit training session and discussed nutrition-related aspects. The active control group (SoSu) had the opportunity to perform cognitive training in addition to the social contact. Outcome measures as nutritional (Mini Nutritional Assessment long form [MNA-LF]) and frailty status (Frailty Instrument for Primary Care of the Survey of Health, Ageing and Retirement in Europe [SHARE-FI]) were obtained at baseline and after 12 weeks. Significant improvements in the MNA-LF score (1.54 points, 95% confidence interval [CI] 0.51-2.56; P = .004) and the SHARE-FI score (-0.71 discrete factor score values, 95% CI -1.07, -0.35; P malnutrition and frailty in older persons living at home. Furthermore, social support alone also can result in improvement. In particular, older adults with impaired nutritional status at baseline can benefit more from the intervention. Such a home visit program might also have the potential to prevent future health risks and could allay isolation and loneliness.

Context: Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before ad...

Cardiorespiratory and biochemical indicators typically used by contemporary elite athletes seem to have limited applicability. According to some recent studies, purine metabolism better reflects exercise response and muscle adaptation in this group. We propose using purine derivatives, especially plasma hypoxanthine concentration, as indicators of training status in consecutive training phases in highly trained athletes.
Full Text Available Introduction: This is an empirical article aiming at defining the changes of motor fitness in children practicing swimming at early stage of training in year-long training cycle. Proper selection of candidates to practice certain sports is a very complex process. One needs to select from the very large population of children, girls and boys, characterized by certain features, including somatic and motor features, which developed in a longstanding process of training, will lead them to become champions. The purpose of the research: The purpose of the research was to define the changes of motor fitness in girls’ practicing swimming at early stage of training in year-long training cycle. Material and Methods: The subjects to the research were 85 girls aged 7 (1st year of primary school, including 36 girls in swimming group and 49 girls in control group. 36 of them belonged to swimmers’ group- all girls were members of the Municipal Swimming Club in Szczecin. Control group consisted of 49 girls, who attended the same elementary schools. The examinations were carried out twice in the 2009-2010 academic year. The most reliable and accurate indirect test- EUROFIT Test Battery-was used. Results : The research revealed changes in both groups (Sw, C in terms of all eight tests. Examination II proved statistically significant improvement of results in both groups (Sw, C in comparison to Examination I. The dynamics of changes in general balance, flexibility, static force, functional force, running agility, was bigger in the girls who practiced swimming. As the speed of movement of upper limb, explosive force and thorax force are concerned; the differences of results in both examinations were similar in both groups (swimming group and control group. Progressive changes in motor fitness of the examined groups are a positive phenomenon in the development of child’s young organism. Conclusions: Swimming training significantly affected the dynamics of

The associations between internal and external measures of training load and intensity are important in understanding the training process and the validity of specific internal measures. We aimed to provide meta-analytic estimates of the relationships, as determined by a correlation coefficient, between internal and external measures of load and intensity during team-sport training and competition. A further aim was to examine the moderating effects of training mode on these relationships. We searched six electronic databases (Scopus, Web of Science, PubMed, MEDLINE, SPORTDiscus, CINAHL) for original research articles published up to September 2017. A Boolean search phrase was created to include search terms relevant to team-sport athletes (population; 37 keywords), internal load (dependent variable; 35 keywords), and external load (independent variable; 81 keywords). Articles were considered for meta-analysis when a correlation coefficient describing the association between at least one internal and one external measure of session load or intensity, measured in the time or frequency domain, was obtained from team-sport athletes during normal training or match-play (i.e., unstructured observational study). The final data sample included 122 estimates from 13 independent studies describing 15 unique relationships between three internal and nine external measures of load and intensity. This sample included 295 athletes and 10,418 individual session observations. Internal measures were session ratings of perceived exertion (sRPE), sRPE training load (sRPE-TL), and heart-rate-derived training impulse (TRIMP). External measures were total distance (TD), the distance covered at high and very high speeds (HSRD ≥ 13.1-15.0 km h -1 and VHSRD ≥ 16.9-19.8 km h -1 , respectively), accelerometer load (AL), and the number of sustained impacts (Impacts > 2-5 G). Distinct training modes were identified as either mixed (reference condition), skills, metabolic, or

Karate is a public sport that has athletes in various age ranges and abundant active sport clubs in Iran. The pattern of injury in this sport in Iranian athletes seems different from other countries. This study was performed with the purpose of considering the incidence and type of injury of karate athletes aged below 30 years from Tehran, Iran clubs. In a cross-sectional study, 10 karate clubs were selected in Tehran. Clubs were selected based on a cluster method from 5 different geographical regions of Tehran. All injuries were collected based on athletes' or clubs' weekly report with a designed questionnaire. The injuries were classified according to: low, medium and severe injury. Collected data was analyzed with SPSS software version 17. 620 athletes were studied totally and incidence rate of injury per athletes was 16.1% and 20.2 per 100 athletes. Ninety percent of injuries were during bout practice, 6% during fitness and 4% during kata. The rate of injury was more common in athletes with weight less than 70 kg and lower sport experience (P ≤ 0.05). The commonest locations for injury were head and neck followed by trunk, lower and upper limb, respectively. Just 2 cases needed surgical intervention and no one led to decreased level of consciousness. The most common type of injury was contusion, bruise and superficial scratch (64%). Severe injury was uncommon in this study and similar to other Iranian studies head and neck had the most injuries. Athletes with lower experience and lower weight were associated with higher injuries.

Modern approaches for emergency management promote exchange of information between local authorities and community aiming at more appropriate and effective ways to manage hydro-meteorological risks1. In this framework, risk communication should not only start during the build-up of the hazard, but also in pre-warning and 'peace' time and it contribute to better emergency preparedness. Lately, a rapid growth of interest emerges to enable citizens to inspect hazard-related processes on their territory2. From the risk managers perspective, substantial advantages of taking this citizen-based approach include (1) the opportunity to identify on a quick and 'relatively' low cost basis one or more risk components at different geographical locations and (2) the ability to provide a practical application for citizens interested in creating and communicating useful information toward establishing a better understanding of their territory. From the citizens perspectives, it provides the opportunity to generate benefit through increasing and encouraging interest for self-awareness as well as self-preparedness. However, the use of citizen-based information also bring forth the need to train and establish standardized forms, guidelines and tools, particularly if the data collected seek to be useful information for decision-making activities and emergency management3. In this research work, we address the question on the quality of data collected by volunteers for decision-making activities. This in the framework of the civil protection organization of the Friuli-Venezia-Giulia (CP-FVG) and the Italian study area of the CHANGES project, Municipality of Pontebba4.

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.

Increased rates of sport participation and sport-related injury have led to greater emphasis on and attention to medical care of student-athletes in the secondary school setting. Access to athletic training services is seen as a critical factor for delivering adequate injury prevention and medical care to student-athletes. However, few data are available regarding practice characteristics of athletic trainers (ATs) in this setting. To characterize the practices of secondary school athletic trainers (ATs). Descriptive study. Web-based survey. A total of 17 558 ATs with current National Athletic Trainers' Association membership were identified for survey distribution. Of these, 4232 ATs indicated that they practiced in the secondary school setting, and 4045 completed some part of the survey. A Web-based survey was used to obtain demographic information about ATs and their secondary schools and characteristics of athletic training practice. Descriptive data regarding the athletic trainer's personal characteristics, secondary school characteristics, and practice patterns are reported as percentages and frequencies. Most respondents were in the early stages of their careers and relatively new to the secondary school practice setting. Nearly two-thirds (62.4%; n = 2522) of respondents had 10 or fewer years of experience as secondary school ATs, 52% (n = 2132) had been certified for 10 or fewer years, and 53.4% (n = 2164) had 10 or fewer years of experience in any practice setting. The majority of respondents (85%) worked in public schools with enrollment of 1000 to 1999 (35.5%) and with football (95.5%). More than half of respondents were employed directly by their school. Most respondents (50.6%) reported an athletic training budget of less than $4000. The majority of ATs performed evaluations (87.5%) on-site all of the time, with a smaller percentage providing treatments (73.3%) or rehabilitation (47.4%) services all of the time. This is the first study to describe

To analyze the effects of 2 different eccentric-overload training (EOT) programs, using a rotational conical pulley, on functional performance in team-sport players. A traditional movement paradigm (ie, squat) including several sets of 1 bilateral and vertical movement was compared with a novel paradigm including a different exercise in each set of unilateral and multi-directional movements. Forty-eight amateur or semiprofessional team-sport players were randomly assigned to an EOT program including either the same bilateral vertical (CBV, n = 24) movement (squat) or different unilateral multidirectional (VUMD, n = 24) movements. Training programs consisted of 6 sets of 1 exercise (CBV) or 1 set of 6 exercises (VUMD) × 6-10 repetitions with 3 min of passive recovery between sets and exercises, biweekly for 8 wk. Functional-performance assessment included several change-of-direction (COD) tests, a 25-m linear-sprint test, unilateral multidirectional jumping tests (ie, lateral, horizontal, and vertical), and a bilateral vertical-jump test. Within-group analysis showed substantial improvements in all tests in both groups, with VUMD showing more robust adaptations in pooled COD tests and lateral/horizontal jumping, whereas the opposite occurred in CBV respecting linear sprinting and vertical jumping. Between-groups analyses showed substantially better results in lateral jumps (ES = 0.21), left-leg horizontal jump (ES = 0.35), and 10-m COD with right leg (ES = 0.42) in VUMD than in CBV. In contrast, left-leg countermovement jump (ES = 0.26) was possibly better in CBV than in VUMD. Eight weeks of EOT induced substantial improvements in functional-performance tests, although the force-vector application may play a key role to develop different and specific functional adaptations.

The chronic exposure to regular exercise training seems to improve antioxidant defense systems. However, the intense physical training imposed on elite athletes may lead to overtraining associated with oxidative stress. The purpose of the present study was to investigate the effect of different training loads and competition on oxidative stress, biochemical parameters and antioxidant enzymatic defense in handball athletes during 6-months of monitoring. Ten male elite handball athletes were recruited to the study. Blood samples were collected four times every six weeks throughout the season. During most intense periods of training and competitions there were significant changes in plasma indices of oxidative stress (increased TBARS and decreased thiols). Conversely, chronic adaptations to exercise training demonstrated a significant protective effect against oxidative stress in erythrocyte (decrease in TBARs and carbonyl group levels). Erythrocyte antioxidant enzyme activities were significantly increased, suggesting a training-induced antioxidant adaptation. Biomarkers of skeletal muscle damage were significantly increased during high-intensity training period (creatine kinase, lactate dehydrogenase and aspartate aminotransferase). No significant changes were observed in plasma IL-6, TNF-α and uric acid, whereas a significant reduction was found in the IL-1β concentration and gamma-glutamyl transferase activity. Oxidative stress and antioxidant biomarkers can change throughout the season in competitive athletes, reflecting the physical stress and muscle damage that occurs as the result of competitive handball training. In addition, these biochemical measurements can be applied in the physiological follow-up of athletes. © 2013.

We examined the effectiveness of video-based decision training in national youth handball teams. Extending previous research, we tested in Study 1 whether a three-dimensional (3D) video training group would outperform a two-dimensional (2D) group. In Study 2, a 3D training group was compared to a control group and a group trained with a traditional tactic board. In both studies, training duration was 6 weeks. Performance was measured in a pre- to post-retention design. The tests consisted of a decision-making task measuring quality of decisions (first and best option) and decision time (time for first and best option). The results of Study 1 showed learning effects and revealed that the 3D video group made faster first-option choices than the 2D group, but differences in the quality of options were not pronounced. The results of Study 2 revealed learning effects for both training groups compared to the control group, and faster choices in the 3D group compared to both other groups. Together, the results show that 3D video training is the most useful tool for improving choices in handball, but only in reference to decision time and not decision quality. We discuss the usefulness of a 3D video tool for training of decision-making skills outside the laboratory or gym.

Sports clubs provide an opportunity to tackle childhood obesity rates through targeted interventions. Our study aimed to investigate if coaches providing healthy snacks to participants before junior netball sessions at five clubs in Melbourne, Australia, increased consumption of healthy foods and influenced coach perceptions of participants' attention/participation levels. Coaches provided healthy snacks to participants before each netball session for one school term. Children's food consumption was observed at one session before, during and after the intervention. Parents attending the observed session completed pre- and post-intervention questionnaires. Coaches rated participants' attention/participation at the observed sessions before and during the intervention, and completed a questionnaire post-intervention. Baseline: Ice cream and cake were the most frequently consumed snacks. During intervention: Fruit, cheese and crackers and vegetables were the most frequently consumed snacks. Coaches ratings of participants' attention/participation increased significantly (baseline: 6.4 ± 0.17, intervention: 7.5 ± 0.36; p=0.02) where the same coach undertook ratings at both time points. Coaches providing healthy snacks before sessions at sports clubs increased consumption of nutrient-dense foods at the session, and may have positively affected participants' attention/participation. Implications for public health: This study highlights how a simple intervention could improve the diet of Australian children. © 2017 The Authors.

To compare sport-specific laboratory capacities and the annual training of world-class Nordic combined (NC) athletes with specialized ski jumpers (SJ) and cross-country (XC) skiers. Five world-class athletes from each sports discipline were compared. Ski jump imitations were performed on a 3-dimensional force plate in NC athletes and SJ, whereas XC skiing characteristics were obtained from submaximal and maximal roller ski skating on a treadmill in NC athletes and XC skiers. In addition, anthropometrics and annual training characteristics were determined. NC athletes demonstrated 9% higher body mass and showed 17% lower vertical speed in the ski jump imitation than SJ (all P ski-jumping-specific sessions and outdoor ski jumps compared with SJ. NC athletes performed 31% less endurance training, mainly caused by lower amounts of low- and moderate-intensity training in the classical technique, whereas high-intensity strength and speed training and endurance training in the skating technique did not differ substantially from XC skiers. To simultaneously optimize endurance, explosive, and technical capacities in 2 different disciplines, world-class NC athletes train approximately two-thirds of the XC skier's endurance training volume and perform one-half of the ski-jump-specific training compared with SJ. Still, the various laboratory capacities differed only 10-17% compared with SJ and XC skiers.

Learning surgical skills involves both fine and gross motor skills, and necessitates performance in stressful situations. This environment is similar to the environment in which an athlete performs. Mental imagery has been used successfully in training athletes of all levels of proficiency and enhances both motor skills and motivational skills of performing under stress. The literature of using mental imagery to train surgeons is limited to the teaching of simple surgical skills, but shows promise as another tool to teach technical skills.

Little research has been done on the physiological and performance effects of altitude training on team-sport athletes. Therefore, this study examined changes in 2000-m time-trial running performance (TT), hemoglobin mass (Hbmass), and intramuscular carnosine content of elite Australian Football (AF) players after a preseason altitude camp. Thirty elite AF players completed 19 days of living and training at either moderate altitude (~2130 m; ALT, n = 21) or sea level (CON, n = 9). TT performance and Hbmass were assessed preintervention (PRE) and postintervention (POST1) in both groups and at 4 wk after returning to sea level (POST2) in ALT only. Improvement in TT performance after altitude was likely 1.5% (± 4.8-90%CL) greater in ALT than in CON, with an individual responsiveness of 0.8%. Improvements in TT were maintained at POST2 in ALT. Hbmass after altitude was very likely increased in ALT compared with CON (2.8% ± 3.5%), with an individual responsiveness of 1.3%. Hbmass returned to baseline at POST2. Intramuscular carnosine did not change in either gastrocnemius or soleus from PRE to POST1. A preseason altitude camp improved TT performance and Hbmass in elite AF players to a magnitude similar to that demonstrated by elite endurance athletes undertaking altitude training. The individual responsiveness of both TT and Hbmass was approximately half the group mean effect, indicating that most players gained benefit. The maintenance of running performance for 4 wk, despite Hbmass returning to baseline, suggests that altitude training is a valuable preparation for AF players leading into the competitive season.

The Amateur Sports Act of 1978 reconstituted the U.S. Olympic Committee ( USOC ), giving it new responsibilities and opportunities as a unifying force in amateur sports, including sports medicine. Sports medicine is the sum of attentions that promote and protect the health of the active person. Olympic sports medicine includes attention to the needs of both the elite athlete and the developing athlete. In some instances the attentions are the same; in others they are not. Those in Olympic sports medicine must thereby reduce the increasing array of general concepts and issues to the applicable specifics of the respective occasion, sport, and individual. The USOC Sports Medicine Program is guided by a 15-person volunteer Sports Medicine Council and implemented by a core Sports Medicine Division staff. Services are provided at the Olympic training centers in Colorado Springs and Lake Placid and extended through a budding network of colleagues in the field to clusters of athletes across the nations. Organizationally , the Division is composed of departments of biomechanics, sports physiology, clinical services, and educational services. Special projects are developed as warranted to provide focal attention to sports psychology, nutrition, chronobiology, vision enhancement, and drug control. The USOC Drug Control Program was born at the 1983 Pan American Games in Caracas after a long gestation period. Drug education in sports has been a frequent activity for the past 20 yr. sometimes focusing on illicit drugs (e.g., marijuana and cocaine) and sometimes on sports performance drugs (e.g., amphetamines and anabolic steroids).(ABSTRACT TRUNCATED AT 250 WORDS)

Competency-based medical education as a resident-training format will move postgraduate training away from time-based training, to a model based on observable outcomes. The purpose of this study was to determine whether junior residents and senior residents could demonstrate clinical skills to a similar level, after a sports medicine rotation. All residents undertaking a three-month sports medicine rotation had to pass an Objective Structured Clinical Examination. The stations tested the fundamentals of history-taking, examination, image interpretation, differential diagnosis, informed consent, and clinical decision-making. Performance at each station was assessed with a binary station-specific checklist and an overall global rating scale, in which 1 indicated novice, 2 indicated advanced beginner, 3 indicated competent, 4 indicated proficient, and 5 indicated expert. A global rating scale was also given for each domain of knowledge. Over eighteen months, thirty-nine residents (twenty-one junior residents and eighteen senior residents) and six fellows (for a total of forty-five participants) completed the examination. With regard to junior residents and senior residents, analysis using a two-tailed t test demonstrated a significant difference (p < 0.01) in both total checklist score and overall global rating scale; the mean total checklist score (and standard deviation) was 56.15% ± 10.99% for junior residents and 71.87% ± 8.94% for senior residents, and the mean global rating scale was 2.44 ± 0.55 for junior residents and 3.79 ± 0.49 for senior residents. There was a significant difference between junior residents and senior residents for each knowledge domain, with a significance of p < 0.05 for history-taking and p < 0.01 for the remainder of the domains.

Perhaps as a consequence of increased specialism in training and support, the focus on engendering and maintaining agility as a generic quality has diminished within many contemporary sports performance programmes. Reflecting this, we outline a rationale suggesting that such a decreased focus represents an oversight which may be detrimental to maximising the potential of performers. We present an evidence-based argument that both generic and specific elements of agility performance should be consistently emphasised within long-term performance-training programmes. We contend that prematurely early specialisation in athlete development models can diminish focus on generic movement skill development with a subsequent detriment in adult performance. Especially when this is coupled with poor primary physical education and limited movement experiences. More speculatively, we propose that generic agility can play a role in operationalising movement development through facilitating skill transfer: thereby enabling the learning of new skills, reduce incidence of injury and facilitating re-learning of old skills during rehabilitation and Return-to-Play processes.

Full Text Available The purpose of the study was to determine the physiological load tolerances of two breeds of dogs used for sports, namely the Siberian husky and the Czechoslovakian wolfdog, on the basis of measurements of surface temperature and blood lactic acid levels.Two breeds - Czechoslovakian wolfdog (10 individuals and Siberian husky (10 individuals, 20 dogs - male, 4-6 years old, were selected for the study. All the qualified animals were previously examined by a veterinarian and considered to be healthy. The dogs tested were used in dogtrekking sport competitions. For both breeds, an attempt was made to test the dogtrekking harness for 5 km of non-stop track running. The animals trotted while being led by a guide. Three attempts were made for each dog at 48 hour intervals. All dogs were tested for two parameters, first before and then after the exercise – measuring surface temperature at selected points of the body as well as lactic acid concentration. A higher and statistically significant level of lactic acid was recorded in the case of Siberian husky. Before the run, the level of lactic acid was comparable in both breeds. The second parameter was the surface temperature measured at the selected measuring points. Significant statistical differences were noted for the wolfdog breed at P≤0.05 before the exercise and 10 minutes after resting, at the neck, rump and abdominal points. In addition, the same level of statistical significance was measured by surface thermography at the abdominal point, both before and immediately after the run. The high statistically significant increase (P≤0.01 in surface temperature was noted for muscles of the so-called rump, both before and after the exertion. There was no statistically significant difference in the back thermography in the wolfdog breed. In the Siberian husky breed, statistically significant differences (P≤0.05 were observed at the neck, rump and chest points, in confrontation with the

The effect of small-sided team sport training and protein intake on muscle mass, physical function, and adaptations important for health in untrained older adults was examined. Forty-eight untrained older (72±6 (±standard deviation, SD) years men and women were divided into either a team sport group ingesting a drink high in protein (18 g) immediately and 3 h after each training session (TS-HP, n = 13), a team sport group ingesting an isocaloric drink with low protein content (3 g; TS-LP, n = 18), or a control group continuing their normal activities (CON, n = 17). The team sport training was performed as ~20 min of small-sided ball games twice a week over 12 weeks. After the intervention period, leg muscle mass was 0.6 kg higher (P = 0.047) in TS-HP, with no effect in TS-LP. In TS-HP, number of sit-to-stand repetitions increased (1.2±0.6, P = 0.054), time to perform 2.45 m up-and-go was lower (0.7±0.3 s, P = 0.03) and number of arm curl repetitions increased (3.5±1.2, P = 0.01), whereas in TS-LP only number of repetitions in sit-to-stand was higher (1.6±0.6, P = 0.01). In TS-LP, reductions were observed in total and abdominal fat mass (1.2±0.5 and 0.4±0.2 kg, P = 0.03 and P = 0.02, respectively), heart rate at rest (9±3 bpm, P = 0.002) and plasma C-reactive protein (1.8±0.8 mmol/L, P = 0.03), with no effects in TS-HP. Thus, team sport training improves functional capacity of untrained older adults and increases leg muscle mass only when ingesting proteins after training. Furthermore, team sport training followed by intake of drink with low protein content does lower fat mass, heart rate at rest and level of systemic inflammation.

Bone marrow edema (BME) at the pubic symphysis on magnetic resonance imaging (MRI) is usually associated with groin pain and stress injury of the pubic bone. Little is known of the pubic MR imaging findings of asymptomatic heavy training athletes in contact sports. Pelvic MRI of male asymptomatic soccer (n=10), ice hockey (n=10), bandy (n=10) and female floor-ball players (n=10) were compared with non-athlete controls (10 males, 10 females) without groin pain to analyse the presence of BME (on a four-point scale). To study the possible changes of BME directly following heavy physical activity, 10 bandy players underwent MRI before and immediately after a 2-h training session. Magnetic resonance imaging showed minimal BME (grade 1) at the pubic symphysis in 19 of the 40 athletes (48%). Two soccer and 2 ice hockey players (20%) had moderate grade 2 pubic edema, but severe grade 3 BME findings were not found. Also 10 out of 20 (50%) of controls had grade 1 BME. The extent of increased signal was equally distributed in the asymptomatic athletes of different contact sports and controls. A heavy 2-h training session did not cause any enhanced signal at the pubic symphysis. This study indicates that the presence of grade 1 pubic BME was a frequent finding in contact sports and comparable to that in non-athletes. Grade 2 BME was found only in asymptomatic athletes undergoing heavy training.

The aim of this study was to evaluate the effects of a standardized exercise program on sports enjoyment and leisure-time spending in adolescents with congenital heart disease and to know what the moderating impact of their baseline health behavior and disease knowledge is. Included were 93 patients, aged 10 to 25, with surgical repair for tetralogy of Fallot or with a Fontan circulation for single-ventricle physiology, of 5 participating centers of pediatric cardiology in The Netherlands. They were randomly allocated, stratified for age, gender, and type of congenital heart disease to a 12-week period with either: (1) three times per week standardized exercise training or (2) care as usual (randomization ratio 2:1). At baseline and after 12 weeks, participants completed Web-based questionnaires and were interviewed by phone. Primary analyses tested changes from baseline to follow-up in sports enjoyment and leisure-time spending in the exercise group vs. control group. Secondary analyses concerned the moderating influence of baseline health behavior and disease knowledge on changes from baseline to follow-up, and comparison with normative data. At follow-up, the exercise group reported a decrease in passive leisure-time spending (watching television and computer usage) compared with controls. Exercise training had no effect on sports enjoyment and active leisure-time spending. Disease knowledge had a moderating effect on improvement in sports enjoyment, whereas health behavior did not. Compared with normative data, patients obtained similar leisure time scores and lower frequencies as to drinking alcohol and smoking. Exercise training decreased passive, but not active, leisure-time spending. It did not influence sports enjoyment. © 2013 Wiley Periodicals, Inc.

Full Text Available This research shows the inadequacies in the training of the Badminton trainers of the province of Pinar del Río, starting from the characteristics of their preparation, defining their needs and establishing their possible solution to eliminate the insufficiencies in their knowledge. That is why they use theoretical and empirical methods such as the historical-logical, the analysis-synthesis, the induction-deduction, the observation, interview, as well as the percentage analysis. Based on the results of the diagnosis, the training needs of these trainers were determined, which will allow the subsequent design and execution of an improvement program to respond to these needs, thus contributing to the overcoming of this technical force, in for superior results.

This paper proposes a new training support method called self-coaching with humanoid robots. In the proposed method, two small size inexpensive humanoid robots are used because of their availability. One robot called target robot reproduces motion of a target player and another robot called reference robot reproduces motion of an expert player. The target player can recognize a target technique from the reference robot and his/her inadequate skill from the target robot. Modifying the motion of the target robot as self-coaching, the target player could get advanced cognition. Some experimental results show some possibility as the new training method and some issues of the self-coaching interface program as a future work.

The dependency of miRNA abundance from physiological processes such as exercises remains partially understood. We set out to analyze the effect of physical exercises on miRNA profiles in blood and plasma of endurance and strength athletes in a systematic manner and correlated differentially abundant miRNAs in athletes to disease miRNAs biomarkers towards a better understanding of how physical exercise may confound disease diagnosis by miRNAs. We profiled blood and plasma of 29 athletes before and after exercise. With four samples analyzed for each individual we analyzed 116 full miRNomes. The study set-up enabled paired analyses of individuals. Affected miRNAs were investigated for known disease associations using network analysis. MiRNA patterns in blood and plasma of endurance and strength athletes vary significantly with differences in blood outreaching variations in plasma. We found only moderate differences between the miRNA levels before training and the RNA levels after training as compared to the more obvious variations found between strength athletes and endurance athletes. We observed significant variations in the abundance of miR-140-3p that is a known circulating disease markers (raw and adjusted p value of 5 × 10(-12) and 4 × 10(-7)). Similarly, the levels of miR-140-5p and miR-650, both of which have been reported as makers for a wide range of human pathologies significantly depend on the training mode. Among the most affected disease categories we found acute myocardial infarction. MiRNAs, which are up-regulated in endurance athletes inhibit VEGFA as shown by systems biology analysis of experimentally validated target genes. We provide evidence that the mode and the extent of training are important confounding factors for a miRNA based disease diagnosis.

Context: Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before adolescence may be deleterious to a young athlete. Evidence Acquisition: PubMed and OVID were searched for English-language articles from 1990 to 2011 discussing sports specialization, expert athletes, or elite versus novice athletes, including original research articles, consensus opinions, and position statements. Results: For most sports, there is no evidence that intense training and specialization before puberty are necessary to achieve elite status. Risks of early sports specialization include higher rates of injury, increased psychological stress, and quitting sports at a young age. Sports specialization occurs along a continuum. Survey tools are being developed to identify where athletes fall along the spectrum of specialization. Conclusion: Some degree of sports specialization is necessary to develop elite-level skill development. However, for most sports, such intense training in a single sport to the exclusion of others should be delayed until late adolescence to optimize success while minimizing injury, psychological stress, and burnout.

The amphetamines can enhance athletic performance. That much seems clear from the literature, some of which is reviewed here. Increases in endurance have been demonstrated in both man and rat. Smith and Beecher, 20 years ago, showed improvement of running, swimming, and weight throwing in highly trained athletes. Laboratory analogues of such performance have also been used and similar enhancement demonstrated. The amount of change induced by the amphetamines is usually small, of the order of a few percent. Nevertheless, since a fraction of a percent improvement can make the difference between fame and oblivion, the margin conferred by these drugs can be quite important.

This paper aimed to systematically review and meta-analyse the training effects of small-sided games (SSG) on physical fitness and specific skills related to team sport according to the level of play and the period of the season. The search covered the following electronic databases (PubMed, Google Scholar, and ScienceDirect). The publications' search period ranged from 2000 to 2016. The terms (small- sided game, training, skill-based game, aerobic fitness, sprint, agility, jump and team sports) were used either singularly or combined in a systematic sequence. Appraisal of 16 articles (15 were meta-analysed) was performed after the application of exclusion criteria and quality assurance processes and the standardized mean effects were measured using random effects. The results revealed that SSG training had a large beneficial effect on maximal oxygen uptake VO2max (effect size 1.94; 95 % CL 0.15, 3.74; I2 = 94 %), agility (-1.49; 95% CL -2.27, -0.71; I2 = 80%), and repeated sprint ability (-1.19; 95% CL - 2.17, -0.21; I2= 53%).There was a moderate beneficial effect on 10- and 20-m sprint performance (-0.89; 95 % CL -1.7, -0.07; I2 =88%), jump height (0.68; 95% CL 0.03, 1.33; I2= 79%), and intermittent endurance (0.61; 95% CL 0.17, 1.05; I2= 0%). The results also showed greater positive effects on specific skills (specific endurance and agility tests and techniques) after SSG when compared with generic or agility training. Small-sided games may represent an effective strategy of multicomponent training that can induce greater positive effects on specific skills tasks when compared with interval or agility training and moderate to large improvements in team sport-related physical fitness.

Full Text Available Specialized studies show how a fighter should physically be, not just any fighter, but the one who possesses the qualities and features of the ideal model, i.e. those elements that define the near-perfect fighter. The demands of the modern battlefield impose a high quality human potential that provides a good basis for the selection and training of fighters. Resistance to physical, climate, season and weather condition demands, to the prolonged efforts fighting requires is one of the important conditions of success. The paper presents information with particular impact in optimizing exercise capacity for future officers of the land forces, emphasizing once again the idea that a high level of motric ability is an essential objective.

Context: Many coaches, parents, and children believe that the best way to develop elite athletes is for them to participate in only 1 sport from an early age and to play it year-round. However, emerging evidence to the contrary indicates that efforts to specialize in 1 sport may reduce opportunities for all children to participate in a diverse year-round sports season and can lead to lost development of lifetime sports skills. Early sports specialization may also reduce motor skill development and ongoing participation in games and sports as a lifestyle choice. The purpose of this review is to employ the current literature to provide evidence-based alternative strategies that may help to optimize opportunities for all aspiring young athletes to maximize their health, fitness, and sports performance. Evidence Acquisition: Nonsystematic review with critical appraisal of existing literature. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Based on the current evidence, parents and educators should help provide opportunities for free unstructured play to improve motor skill development and youth should be encouraged to participate in a variety of sports during their growing years to influence the development of diverse motor skills. For those children who do choose to specialize in a single sport, periods of intense training and specialized sport activities should be closely monitored for indicators of burnout, overuse injury, or potential decrements in performance due to overtraining. Last, the evidence indicates that all youth should be involved in periodized strength and conditioning (eg, integrative neuromuscular training) to help them prepare for the demands of competitive sport participation, and youth who specialize in a single sport should plan periods of isolated and focused integrative neuromuscular training to enhance diverse motor skill development and reduce injury risk factors.

The Faculty of Pharmaceutical Sciences, Setsunan University, offers the Self-improvement and Participatory Career Development Education Program: Internship and Volunteer Training Experience for Pharmacy Students to third-year students. We previously reported that the training experience was effective in cultivating important attributes among students, such as a willingness to learn the aims of pharmacists, an awareness of their own role as healthcare workers, and a desire to reflect on their future careers and lives. A follow-up survey of the participants was carried out three years after the training experience. The questionnaire verified that the training experience affected attendance at subsequent lectures and course determination after graduation. We confirmed the relationship between the participants' degree of satisfaction with the training experience and increased motivation for attending subsequent lectures. Through the training experience, participants discovered future targets and subjects of study. In addition, they became more interested in subsequent classroom lessons and their future. The greater the participants' degree of satisfaction with their training experience, the more interest they took in practical training and future courses. The present study clarified that the training experience was effective in cultivating important attributes such as a willingness to learn and an interest in future courses. Moreover, the training positively affected the course determination after graduation.
Full Text Available A long-term sports training induces morphological and functional changes in the cardiovascular system, with the activation of angiogenesis being one of the most significant ones. Aim: The aim of the study was to assess the impact of an 8-month sports training on the serum levels of vascular endothelial growth factor and the physical performance in young athletes. Material and methods: A total of 28 sports middle school students (athletics faculty aged 13 years, including 14 boys and 14 girls, were included in the study. All participants underwent clinical assessment at each stage of the study. Electrocardiographic and echocardiographic examinations were performed. Furthermore, the levels of vascular endothelial growth factor were measured and a cardiac stress test was performed, the outcome of which was used to calculate the physical working capacity (PWC170. Results: There was a statistically significant decrease (274.3 ± 195.7 vs. 193.8 ± 153.8 ng/ml, p 0.05. Conclusions: Long-term sports training results in a decrease in the levels of vascular endothelial growth factor. At the same time, physical efficiency improvement is observed, which may suggest the involvement of adaptive, exerciseinduced angiogenesis in the skeletal muscles. However, the observed changes show distinct differences depending on the sex.

Female athletes have a higher risk of anterior cruciate ligament injury than their male counterparts who play at similar levels in sports involving pivoting and landing. The competitive female basketball players who participated in a sports injury prevention training program would show better muscle strength and flexibility and improved biomechanical properties associated with anterior cruciate ligament injury than during the pretraining period and than posttraining parameters in a control group. Controlled laboratory study. A total of 22 high school female basketball players were recruited and randomly divided into 2 groups (the experimental group and the control group, 11 participants each). The experimental group was instructed in the 6 parts of the sports injury prevention training program and performed it during the first 20 minutes of team practice for the next 8 weeks, while the control group performed their regular training program. Both groups were tested with a rebound-jump task before and after the 8-week period. A total of 21 reflective markers were placed in preassigned positions. In this controlled laboratory study, a 2-way analysis of variance (2 x 2) experimental design was used for the statistical analysis (P training effects on all strength parameters (P = .004 to .043) and on knee flexion, which reflects increased flexibility (P = .022). The experimental group showed higher knee flexion angles (P = .024), greater interknee distances (P = .004), lower hamstring-quadriceps ratios (P = .023), and lower maximum knee extension torques (P = .043) after training. In the control group, no statistical differences were observed between pretraining and posttraining findings (P = .084 to .873). At pretraining, no significant differences were observed between the 2 groups for any parameter (P = .067 to .784). However, a comparison of the 2 groups after training revealed that the experimental group had significantly higher knee flexion angles (P = .023
Physical exercise is known to regulate energy balance. Important to this regulatory system is the existence of several peptides that communicate the status of body energy stores to the brain and are related to the body fatness including leptin, adiponectin and ghrelin. These hormones assist in regulating energy balance as well as somatic and pubertal growth in children. It appears that rather few studies have investigated the responses of leptin, adiponectin and ghrelin to acute exercise and these studies have demonstrated no changes in these peptides as a result of exercise. Leptin levels are decreased and may remain unchanged advancing from prepuberty to pubertal maturation in young male and female athletes. A limited number of studies indicate that adiponectin levels are not different between prepubertal and pubertal athletes and untrained controls. However, in certain circumstances circulating adiponectin could be increased in young athletes after onset of puberty as a result of heavily increased energy expenditure. Ghrelin levels are elevated in young sportsmen. However, pubertal onset decreases ghrelin levels in boys and girls even in the presence of chronically elevated energy expenditure as seen in young athletes. Ghrelin may also be used as an indicator of energy imbalance across the menstrual cycle in adolescent athletes. There are no studies with high-molecular-weight adiponectin and only very few studies with acylated ghrelin responses to acute exercise and chronic training have been performed in young athletes. Since these forms of adiponectin and ghrelin have been thought to be bioactive forms, further studies with these specific forms of adiponectin and ghrelin are needed. In conclusion, further studies should be conducted to investigate the response of these hormones to acute and chronic negative energy balance to better understand their role in regulating energy balance during growth and maturation in young athletes.

Identification of strategies to prevent spinal injury, optimize rehabilitation, and enhance performance is a priority for practitioners. Different exercises produce different effects on neuromuscular performance. Clarity of the purpose of a prescribed exercise is central to a successful outcome. Spinal exercises need to be classified according to the objective of the exercise and planned physical outcome. To define the modifiable spinal abilities that underpin optimal function during skilled athletic performance, clarify the effect of spinal pain and pathologic conditions, and classify spinal exercises according to the objective of the exercise and intended physical outcomes to inform training and rehabilitation. Qualitative study. We conducted a qualitative consensus method of 4 iterative phases. An exploratory panel carried out an extended review of the English-language literature using CINAHL, EMBASE, MEDLINE, and PubMed to identify key themes and subthemes to inform the definitions of exercise categories, physical abilities, and physical outcomes. An expert project group reviewed panel findings. A draft classification was discussed with physiotherapists (n = 49) and international experts. Lead physiotherapy and strength and conditioning teams (n = 17) reviewed a revised classification. Consensus was defined as unanimous agreement. After the literature review and subsequent analysis, we defined spinal abilities in 4 categories: mobility, motor control, work capacity, and strength. Exercises were subclassified by functionality as nonfunctional or functional and by spinal displacement as either static (neutral spinal posture with no segmental displacement) or dynamic (dynamic segmental movement). The proposed terminology and classification support commonality of language for practitioners. The spinal-exercise classification will support clinical reasoning through a framework of spinal-exercise objectives that clearly define the nature of the exercise prescription

Full Text Available We can say that sports are continuously evolving. To improve the quality of this work, changes are being made in all of these segments: development and selection of athletes, the improvement of technology for preparation and performance tactics, training methods for relaxation. On the other hand these are followed by rule changes, modern sports facilities, as well as legal regulations. One direction in the improvement of sports results is an attempt at rational spending of existing resources for athletes, regardless of whether in team or individual sports. Nanotechnology is also contributioning toward this direction. This paper points out the appearance of nanotechnology, its essence, i.e., the way it may effect the development of sports. Of course, it also points to the potential risk of applying nanotechnology to sports.

Several studies comparing adult musicians and non-musicians have provided compelling evidence for functional and anatomical differences in the brain systems engaged by musical training. It is not known, however, whether those differences result from long-term musical training or from pre-existing traits favoring musicality. In an attempt to begin addressing this question, we have launched a longitudinal investigation of the effects of childhood music training on cognitive, social and neural development. We compared a group of 6- to 7-year old children at the start of intense after-school musical training, with two groups of children: one involved in high intensity sports training but not musical training, another not involved in any systematic training. All children were tested with a comprehensive battery of cognitive, motor, musical, emotional, and social assessments and underwent magnetic resonance imaging and electroencephalography. Our first objective was to determine whether children who participate in musical training were different, prior to training, from children in the control groups in terms of cognitive, motor, musical, emotional, and social behavior measures as well as in structural and functional brain measures. Our second objective was to determine whether musical skills, as measured by a music perception assessment prior to training, correlates with emotional and social outcome measures that have been shown to be associated with musical training. We found no neural, cognitive, motor, emotional, or social differences among the three groups. In addition, there was no correlation between music perception skills and any of the social or emotional measures. These results provide a baseline for an ongoing longitudinal investigation of the effects of music training.

The present study aimed to assess the effects of two different sports training methods - traditional and maturational - on the flexibility of female rhythmic gymnasts at different levels of biological maturation. The sample consisted of 120 children, randomly divided (by draw) into six groups of 20 children (eight and nine-years old): traditional training group (TG); maturational training group (MG); and the control group (CG). These were subdivided into early, normal and late, based on biological maturation assessment by hand/wrist X-ray examination. Flexibility was evaluated by angle goniometer testing, applying the LABIFIE protocol. A Lafayette Goniometer Set and Hoorn-Brasil exercise mat were used and the following exercises were performed: external shoulder rotation (ESR) and lumbar flexion (LF). Both the TG and MG participated in twice-weekly, 45-minute rhythmic gymnastics classes over 16 weeks. The TG used the traditional sports training method while the MG executed sporting activities according to biological maturation. The CG received no special treatment. The results showed a significant improvement (P<0.001) in the subgroups (late, normal and early) for both variables (∆ESR=7.54º and ∆LF=7.51º) in the eight and nine-year age groups. Moreover, in relation to division by biological maturity, better results were recorded in the early subgroups. Thus, it can be inferred that, due to the changes in important physical parameters as a result of maturation, selecting children for physical education should not be based solely on chronological, but primarily on biological maturation.

Volunteer computing projects (VCPs) have been set up by groups of scientists to recruit members of the public who are asked to donate spare capacity on their personal computers to the processing of scientific data or computationally intensive models. VCPs serve two purposes: to acquire significant computing capacity and to educate the public about science. A particular challenge for these scientists is the retention of volunteers as there is a very high drop-out rate. This paper develops recommendations for scientists and software engineers setting up or running VCPs regarding which strategies to pursue in order to improve volunteer retention rates. These recommendations are based on a qualitative study of volunteers in a VCP (climateprediction.net). A typology of volunteers has been developed, and three particularly important classes of volunteers are presented in this paper: for each type of volunteer, the particular benefits they offer to a project are described, and their motivations for continued participation in a VCP are identified and linked to particular strategies. In this way, those setting up a VCP can identify which types of volunteers they should be particularly keen to retain, and can then find recommendations to increase the retention rates of their target volunteers.

To determine whether resistance training to improve mobility outcomes after stroke adheres to the American College of Sports Medicine (ACSM) guidelines, and whether adherence was associated with better outcomes. Online databases searched from 1975 to October 30, 2016. Randomized controlled trials examining the effectiveness of lower limb strength training on mobility outcomes in adult participants with stroke. Two independent reviewers completed data extraction. Quality of trials was determined using the Cochrane Risk of Bias Tool. Trials were scored based on their protocol's adherence to 8 ACSM recommendations. To determine if a relation existed between total adherence score and effect size, Spearman ρ was calculated, and between individual recommendations and effect size, Mann-Whitney U or Kruskal-Wallis tests were used. Thirty-nine trials met the inclusion criteria, and 34 were scored on their adherence to the guidelines. Adherence was high for frequency of training (100% of studies), but few trials adhered to the guidelines for intensity (32%), specificity (24%), and training pattern (3%). Based on the small number of studies that could be included in pooled analysis (n=12), there was no relation between overall adherence and effect size (Spearman ρ=-.39, P=.21). Adherence to the ACSM guidelines for resistance training after stroke varied widely. Future trials should ensure strength training protocols adhere more closely to the guidelines, to ensure their effectiveness in stroke can be accurately determined.

Full Text Available Abstract Background Sport drinks are ubiquitous within the recreational and competitive fitness and sporting world. Most are manufactured and artificially flavored carbohydrate-electrolyte beverages. Recently, attention has been given to coconut water, a natural alternative to manufactured sport drinks, with initial evidence indicating efficacy with regard to maintaining hydration. We compared coconut water and a carbohydrate-electrolyte sport drink on measures of hydration and physical performance in exercise-trained men. Methods Following a 60-minute bout of dehydrating treadmill exercise, 12 exercise-trained men (26.6 ± 5.7 yrs received bottled water (BW, pure coconut water (VitaCoco®: CW, coconut water from concentrate (CWC, or a carbohydrate-electrolyte sport drink (SD [a fluid amount based on body mass loss during the dehydrating exercise] on four occasions (separated by at least 5 days in a random order, single blind (subject and not investigators, cross-over design.

Full Text Available Being a significant area of human activity, sport has multiple functions. One of the more important functions of sport, especially top sport, is the inventive heuristic function. Creative work, being a process of creating new values, represents a significant possibility for advancement of sport. This paper aims at pointing at the various dimensions of human creative work, at the creative work which can be seen in sport (in a narrow sense and at the scientific and practical areas which borderline sport. The method of theoretical analysis of different approaches to the phenomenon of creative work , both in general and in sport, was applied in this paper. This area can be systematized according to various criterion : the level of creative work, different fields where it appears, the subjects of creative work - creators etc. Case analysis shows that the field of creative work in sport is widening and deepening constantly. There are different levels of creativity not only in the system of training and competition, but in a wider social context of sport as well. As a process of human spirit and mind the creative work belongs not just to athletes and coaches, but also to all the people and social groups who's creative power manifests itself in sport. The classification of creative work in sport according to various criterion allows for heuristic function of sport to be explained comprehensively and to create an image how do the sparks of human spirit improve the micro cosmos of sport. A thorough classification of creative work in sport allows for a detailed analysis of all the elements of creative work and each of it’s area in sport. In this way the progress in sport , as a consequence of innovations in both competitions and athletes’ training and of everything that goes with those activities, can be guided into the needed direction more easily as well as studied and applied.

Maximum running speed and acceleration are essential components in many sports. The identification of specific training protocols to maximize sprint speed would be useful knowledge for coaches and players. The purpose of this study was to determine the effect of a high-speed treadmill (HST) with the use of a body weight support (BWS) system in a 6-week sport acceleration program (SAP) on female soccer athlete's 40-yard sprint time and maximal isometric knee flexor and extensor strength. Two treatment groups and one control group were created. Both treatment groups participated in a 12-session SAP. The first treatment group (n = 12) used a BWS system while running on a HST; the second group (n = 12) used a standard treadmill (ST) with no BWS system. The participants of the control group (n = 8), NT, did not participate in a sports acceleration program and did not alter their exercise routines outside of the study. An analysis of covariance was performed using baseline measures as the covariate. The 40-yard sprint times for both treatment groups were shown to improve significantly compared with the control group (p strength showed a greater increase in the ST group (p = 0.026) than in the other 2 groups, whereas knee extensor strengths did not show significant differences between treatment groups and control group (p > 0.05). Participants in the ST group had a much higher rate (66%) of shin splints and foot pain throughout the study than those in the HST (8%) and NT (0%) groups. These results can help high school coaches and athletes determine the optimal treadmill training regime.

The aim of this investigation was to assess the influence of an 8-month physical training period on left ventricular voltages identified by resting ECG in relation to changes in left ventricle mass in adolescent athletes. The study encompassed 28 adolescents aged 13 years (14 boys and 14 girls) from a sports secondary school. Clinical assessment was performed on all athletes before and after 8 months of physical training. Sokolov-Lyon voltage index, Cornell voltage index, and maximum spatial QRS vector magnitude demonstrated statistically significant decline during the study period. The specific potential of the myocardium also significantly decreased during 8 months of training. The Sokolov-Lyon voltage criterion for left ventricular hypertrophy was fulfilled in 9 athletes (32.1%) at the beginning of the observation and only in 3 athletes (10.7%) at the end of the study. On the other hand, mean left ventricular mass and mean left ventricular mass index significantly increased after long-term training. No statistically significant correlations were identified between relative changes in left ventricular mass and QRS voltages. An early period of intensive physical training in young athletes is associated with a decrease in QRS amplitude and a relative voltage deficit over the left ventricle.

The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

Although hospice volunteer programs contribute to patient care, little is known about their utilization and adaptation of technology. A survey was posted to the Hospice Volunteer Association Web site to assess technology use among volunteer coordinators and volunteers. Results revealed that participants have access to computers, Internet, and e-mail at the hospice agency and routinely use cellular phones and e-mail. Despite the use of technology, communication problems with volunteers hindered the coordinator's ability to manage scheduling, training, and volunteer assignments for patient care. Coordinators and volunteers felt comfortable utilizing technology but were less comfortable using technology in the patients' home. Several areas are identified for development and integration of advanced technology in volunteer programs. Future research is needed to ease technology implementation and increase volunteer acceptance.

Altitud y deportes de equipo: métodos tradicionales desafiados por un entrenamiento innovador y específico en hipoxia. [Altitude and team sports: traditional methods challenged by innovative sport-specific training in hypoxia].
level but train under hypoxic conditions, has gained unprecedented popularity. A thorough analysis of studies including IHT, however, leads to strikingly poor benefits for sea-level performance improvement, compared to the same training method performed in normoxia. Despite positive molecular adaptations observed after various IHT modalities, the characteristics of optimal training stimulus in hypoxia are still unclear and their functional translation in term of whole-body performance enhancement is minimal. To overcome some of the inherent limitations of IHT (lower workload due to hypoxia, recent studies have successfully investigated a new training method based on the repetition of short sprints with incomplete recoveries in hypoxia; named RSH. Additionally, the growing scientific interest on the practical application of hypoxic training legitimizes the development of innovative technologies serving athletes in a sport-specific setting. The aims of the present review are therefore threefold. First, to critically analyze the results of the studies involving high-intensity exercises performed in hypoxia for sea-level performance enhancement by differentiating IHT and RSH. Second, to discuss the potential mechanisms underpinning their effectiveness and their inherent limitations. Third, to present the potentials benefits of using new technological innovation (i.e., the mobile inflatable simulated hypoxic system which will undoubtedly contribute to the understanding advancement of hypoxia-induced physiological adaptations by conducting relevant research in the most sport-specific ecological test setting.

In all, 119 hospice palliative care volunteers from 3 community-based hospice programs completed the Volunteer Retention Questionnaire (VRQ), a 33-item survey designed for this study. The VRQ asks volunteers to rate the importance of each item to their decision to continue volunteering. The items that received the highest mean importance ratings included enjoying the work they do, feeling adequately prepared/trained to perform their role, and learning from their patients' experiences/listening to their patients' life stories. Being recognized (eg, pins for years of service or being profiled in the hospice newsletter), receiving phone calls/cards from their volunteer coordinator on special occasions, and being reimbursed for out-of-pocket expenses were among the items that received the lowest mean importance ratings. Suggestions for improving volunteer retention are provided.

The study investigated the effects of a Special Olympics (SO) Unified Sport (UNS) soccer program on anthropometry, physical fitness and soccer skills of male youth athletes with and without intellectual disabilities (ID) who participated in a training group (TRG) and in a comparison group (CG) without specific training. Youth with ID (WID) were randomly selected out of all the students between the ages 12 and 15, with a diagnosis of educable mental retardation and no secondary disabilities, who were attending a special education school. Participants without ID (WoID) were randomly selected from a regular secondary school out of the same age groups of male students. All participants were given permission by their parents or guardians to participate in the study. Participants in the TRG included 23 youth WID and 23 youth WoID. Mean ages were = 14.1 (SD = 1.1) and 13.2 (SD = 0.79) respectively. Fifteen WID, and 15 WoID comprised the CG. Mean ages were 14.51 (SD = 0.81) and 13.78 (SD = 0.49) respectively. Prior to and following the program measurements were conducted, and data were collected on students' anthropometric and fitness components of the Brockport physical fitness test as well as a soccer skill performance based on the SO soccer skill test. Participants in the TRG trained 8 weeks, 1.5h per session, three times per week, in an after-school soccer program. CG did not participate in any sports program outside of the school physical education class. Dependent t tests and effect size calculations revealed that SO athletes and non-disabled partners scored significantly higher with regard to physical fitness and football skills in most variables compared with their CG. This Unified Program was successful in increasing fitness and soccer skill performance of youth WID as well as of those WoID. Copyright © 2012 Elsevier Ltd. All rights reserved.

As a sub-speciality, Sports Cardiology focuses on sport and physical training interacting with cardiac issues. Particularly, Sports Cardiology deals with the so-called "Sports Paradox", which implicates the fact the on one side regular physical training leads to a multitude of relevant health benefits. But on the other hand, exercise can also be a trigger for sudden cardiac death, particularly in case of an underlying cardiac disease. However, health benefits by regular training outweigh potential risks by far, but only if an adequate cardiac screening and individual recommendations for sports participation have been provided. This review highlights various aspects of Sports Cardiology like strategies to prevent sudden cardiac death in sports and training recommendations in patients with an underlying cardiovascular disease.

The study tested utility of self-determination and sport commitment theories to understanding young athletes' sport commitment. 343 young athletes (M= 13.5 yr., SD= +/- 1.1) from soccer, basketball, volleyball, handball, and water polo teams volunteered to participate. All completed the Sport Motivation Scale and the Sport Commitment Questionnaire. Pearson correlations showed a strong relationship between commitment and intrinsic motivation scores. In contrast, extrinsic motivation scores were not significantly correlated to commitment, whereas amotivation scores showed a negative correlation to commitment. Path analysis resulted in strong positive association of intrinsic motivation and commitment. Amotivation had small negative relation to commitment. According to the model tested, social constraints and involvement opportunities were not significant contributors to sport commitment. An alternative model supported the mediating role of enjoyment to psychological commitment. The results showed that high self-determination is supportive of sport commitment, whereas low self-determination reduces sport commitment.

While adaptation to hypoxia at natural or simulated altitude has long been used with endurance athletes, it has only recently gained popularity for team-sport athletes. To analyse the effect of hypoxic interventions on high-intensity intermittent running performance in team-sport athletes. A systematic literature search of five journal databases was performed. Percent change in performance (distance covered) in the Yo-Yo intermittent recovery test (level 1 and level 2 were used without differentiation) in hypoxic (natural or simulated altitude) and control (sea level or normoxic placebo) groups was meta-analyzed with a mixed model. The modifying effects of study characteristics (type and dose of hypoxic exposure, training duration, post-altitude duration) were estimated with fixed effects, random effects allowed for repeated measurement within studies and residual real differences between studies, and the standard-error weighting factors were derived or imputed via standard deviations of change scores. Effects and their uncertainty were assessed with magnitude-based inference, with a smallest important improvement of 4% estimated via between-athlete standard deviations of performance at baseline. Ten studies qualified for inclusion, but two were excluded owing to small sample size and risk of publication bias. Hypoxic interventions occurred over a period of 7-28 days, and the range of total hypoxic exposure (in effective altitude-hours) was 4.5-33 km h in the intermittent-hypoxia studies and 180-710 km h in the live-high studies. There were 11 control and 15 experimental study-estimates in the final meta-analysis. Training effects were moderate and very likely beneficial in the control groups at 1 week (20 ± 14%, percent estimate, ± 90% confidence limits) and 4-week post-intervention (25 ± 23%). The intermittent and live-high hypoxic groups experienced additional likely beneficial gains at 1 week (13 ± 16%; 13 ± 15%) and 4-week post

A recent study reported elevated concentrations of perfluorooctane sulfonic acid (PFOS) and other perfluoroalkyl acids (PFAAs) in surface water, snapping turtles, and amphipods in Lake Niapenco, downstream of Hamilton International Airport, Ontario, Canada. Here, our goals were to 1) determine the extent of PFAA contamination in sport fish species collected downstream of the airport, 2) explore if the airport could be a potential source, and 3) compare fish PFOS concentrations to consumption advisory benchmarks. The PFOS levels in several sport fish collected from the three locations closest to the airport (70km) were comparable to or below the average concentrations in fish as observed in the literature and were generally below the benchmarks. With regards to perfluorocarboxylates (PFCAs), there was no significant decrease in concentrations in fish with distance from the airport and levels were comparable to or below the average concentrations observed in the literature, suggesting that the airport is not a significant source of PFCAs in these fish species. PFOS-based aqueous film-forming foam (AFFF) was used at a firefighting training facility at the airport in the 1980s to mid-1990s. Taken together, our results provide evidence that the historical use of AFFF at the airport has resulted in fish PFOS concentrations that exceed the 95th percentile concentration of values reported in the literature to date.

Sport-confidence is considered a critical success factor for sport performers at all levels. Researchers have suggested that sport-confidence is a multidimensional rather than a unidimensional construct, and the sport-confidence model identified three types of sport-confidence (i.e., physical skills and training, cognitive efficiency, and resilience) that are important for success in sport. However, such multidimensionality of sport-confidence and its measurement have not been fully examined. On a large sample of sport performers with varied skill levels and characteristics, the purpose of the present study was to examine the three-factor model of sport-confidence. We tested the measurement invariance of the Sport-Confidence Inventory across 512 athletes and 1170 non-athlete sport performers. Results from the multiple group model analysis showed that the three-factor model of sport-confidence fit better for the athlete sample than for the non-athlete sample. The results implicate that the three-factor model of sport-confidence model is suitable to athletes, though sport-confidence may appear more unidimensional for non-athletes. The use of the Sport-Confidence Inventory for non-athlete sport performers demands further consideration; however, the findings implicate that it could be a useful tool to assess sport-confidence of sport performers at any levels.

Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2-3 games over a weekend road trip in others, and a tournament fixture usually involves 1-3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance. Copyright © 2011 S.

The current study investigated the effects of a pre-cooling intervention on physiological and performance responses to team-sport training in the heat. Seven male lacrosse players performed a familiarization session and 2 randomized, counterbalanced sessions consisting of a 30-minute intermittent-sprint conditioning session. Prior to the sessions, players performed a 20-minute mixed-method, part-body cooling intervention (consisting of cooling vests, cold towels to the neck, and ice packs to the quadriceps) or no cooling intervention. Performance was determined from collection of 1 Hz global positioning system (GPS) data and analyzed for distance and speed. Prior to, during, and following the sessions, core temperature, heart rate, rating of perceived exertion (RPE), and thermal sensation scale (TSS) were measured; additionally, a venous blood sample was collected before and after each session for measurement of interleukin-6 (IL-6), insulin-like growth factor (IGF-1) and insulin-like growth factor-binding protein3 (IGF-BP3). Results indicated that a greater distance was covered during the pre-cooling condition (3.35 +/- 0.20 vs. 3.11 +/- 0.13 km; p = 0.05). Further, most of this improvement was evident from a greater distance covered during moderate intensities of 7 to 14 km/h (2.28 +/- 0.18 vs. 2.00 +/- 0.24 km; p = 0.05). Peak speeds and very-high-intensity efforts (20 km/h +/-) were not different between conditions (p > 0.05). The increase in core temperature was blunted following cooling, with a lower core temperature throughout the cooling session (38.8 +/- 0.3 vs. 39.3 +/- 0.4 degrees C; p 0.05). Accordingly, the use of a mixed-method, part-body cooling intervention prior to an intermittent-sprint training session in the heat can assist in reducing thermoregulatory load and improve aspects of training performance for team sports.

This study tested a theoretical model of volunteering benefits and examined the mechanism through which volunteering benefits older adults. This is a 2-wave study of 253 older adult volunteers serving in 10 volunteer programs. Older volunteers completed the mailed surveys in 2005 and 2006. Structural equation modeling was used to define the latent variables and to test direct and indirect relationships among organizational support, socioemotional benefits, and self-reported health. Organizational support (measured by choice of volunteer activity, training, and ongoing support) had significant direct associations with 2 latent factors of socioemotional benefits, that is, perceived contribution and personal benefits. Perceived contribution was significantly related to mental health. Additionally, older volunteers with lower socioeconomic status (SES) committed more hours and perceived more personal benefits than higher SES peers. These findings suggest that volunteer programs can provide various organizational supports to older volunteers, especially to low-SES volunteers, in order to promote the socioemotional and health benefits of volunteering to older adults. Psychological well-being of older adults can be improved through engagement in meaningful volunteer activities and contribution to others.

Improvements in 180-degree COD performance was recorded at all test-points following EPE (ES = −1.32 to −0.15. Improvements in 45-degree COD performance were apparent for FAST following CON (ES = −0.96 to 0.10, but CON was deleterious for SLOW (ES = −0.60 to 1.53. Eccentric phase-emphasis strength training shows potential for sustained strength enhancement. Positive performance changes in COD tasks were category- and condition-specific. The data indicate the greatest improvement occurred at nine weeks following resistance training in these players. Performance benefits may also be specific to COD task, player category, and relative to emphasis on eccentric phase activity.

Athletes are among the groups of people who are interested in the effects of caffeine on endurance and exercise capacity. Although many studies have investigated the effect of caffeine ingestion on exercise, not all are suited to draw conclusions regarding caffeine and sports performance. Characteristics of studies that can better explore the issues of athletes include the use of well-trained subjects, conditions that reflect actual practices in sport, and exercise protocols that simulate real-life events. There is a scarcity of field-based studies and investigations involving elite performers. Researchers are encouraged to use statistical analyses that consider the magnitude of changes, and to establish whether these are meaningful to the outcome of sport. The available literature that follows such guidelines suggests that performance benefits can be seen with moderate amounts (~3 mg.kg-1 body mass) of caffeine. Furthermore, these benefits are likely to occur across a range of sports, including endurance events, stop-and-go events (e.g., team and racquet sports), and sports involving sustained high-intensity activity lasting from 1-60 min (e.g., swimming, rowing, and middle and distance running races). The direct effects on single events involving strength and power, such as lifts, throws, and sprints, are unclear. Further studies are needed to better elucidate the range of protocols (timing and amount of doses) that produce benefits and the range of sports to which these may apply. Individual responses, the politics of sport, and the effects of caffeine on other goals, such as sleep, hydration, and refuelling, also need to be considered.

Full Text Available Abstract Background With the relatively high rate of injuries to the lower extremity due to jump-landing movement patterns and the accompanied high costs, there is need for determining potential preventive programs. A program on the intervention of jump-landing technique is possibly an important preventative measure since it appeared to reduce the incidence of lower extremity injuries. In real life situations, amateur sports lack the infrastructure and funds to have a sports physician or therapist permanently supervising such a program. Therefore the current prevention program is designed so that it could be implemented by coaches alone. Objective The objective of this randomized controlled trial is to evaluate the effect of a coach supervised intervention program targeting jump-landing technique on the incidence of lower extremity injuries. Methods Of the 110 Flemish teams of the elite division, 24 teams are included and equally randomized to two study groups. An equal selection of female and male teams with allocation to intervention and control group is obtained. The program is a modification of other prevention programs previously proven to be effective. All exercises in the current program are adjusted so that a more progressive development in the exercise is presented. Both the control and intervention group continue with their normal training routine, while the intervention group carries out the program on jump-landing technique. The full intervention program has a duration of three months and is performed 2 times a week during warm-up (5-10 min. Injuries are registered during the entire season. Discussion The results of this study can give valuable information on the effect of a coach supervised intervention program on jump-landing technique and injury occurrence. Results will become available in 2011. Trial registration Trial registration number: NTR2560

Development disorders and delays are recognised as a public health priority and included in the WHO mental health gap action programme (mhGAP). Parents Skills Training (PST) is recommended as a key intervention for such conditions under the WHO mhGAP intervention guide. However, sustainable and scalable delivery of such evidence based interventions remains a challenge. This study aims to evaluate the effectiveness and scaled-up implementation of locally adapted WHO PST programme delivered by family volunteers in rural Pakistan. The study is a two arm single-blind effectiveness implementation-hybrid cluster randomised controlled trial. WHO PST programme will be delivered by 'family volunteers' to the caregivers of children with developmental disorders and delays in community-based settings. The intervention consists of the WHO PST along with the WHO mhGAP intervention for developmental disorders adapted for delivery using the android application on a tablet device. A total of 540 parent-child dyads will be recruited from 30 clusters. The primary outcome is child's functioning, measured by WHO Disability Assessment Schedule - child version (WHODAS-Child) at 6 months post intervention. Secondary outcomes include children's social communication and joint engagement with their caregiver, social emotional well-being, parental health related quality of life, family empowerment and stigmatizing experiences. Mixed method will be used to collect data on implementation outcomes. Trial has been retrospectively registered at ClinicalTrials.gov (NCT02792894). This study addresses implementation challenges in the real world by incorporating evidence-based intervention strategies with social, technological and business innovations. If proven effective, the study will contribute to scaled-up implementation of evidence-based packages for public mental health in low resource settings.

The goal of this randomized and controlled study was to examine whether whole-body vibration (WBV) training is able to reduce back pain and physical disability in seated working office employees with chronic low-back pain in a real-world setting. A total of 41 subjects (68.3% female/mean age 45.5±9.1 years/mean BMI 26.6±5.2) were randomly allocated to an intervention group (INT [n=21]) or a control group (CON [n=20]). The INT participated in WBV training 2.5 times per week for 3 months. The primary outcome was the change in the Roland and Morris disability questionnaire (RMQ) score over the study period. In addition, secondary outcomes included changes in the Oswestry Disability Index (ODI), the Work Ability Index Questionnaire, the quality of life questionnaire SF-36, the Freiburger activity questionnaire, and an isokinetic test of the musculature of the trunk. Compliance with the intervention in the INT reached a mean of 81.1%±31.2% with no long-lasting unwanted side effects. We found significant positive effects of 3 months of WBV training in the INT compared to the CON regarding the RMQ (P=.027), the ODI (P=.002), the SF-36 (P=.013), the Freiburger activity questionnaire (P=.022), the post-interventional sick-leave in the INT (P=.008), and trends regarding a positive effect of the intervention on the muscular capacity of the muscles of the trunk in flexion. WBV training seems to be an effective, safe, and suitable intervention for seated working employees with chronic low-back pain. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We examined reasons of volunteering for hospice and nonhospice organizations in a study with 125 volunteers (22-93 years) from the United States and Germany. Motives of US and German hospice volunteers revealed similarities and few differences. Hospice volunteers are involved because they seek to help others, seek new learning experiences, seek social contacts, or seek personal growth. The US hospice volunteers reported motives related to altruistic concerns, enhancement, and social influence as more influential, while German hospice volunteers rated career expectations as being more important. Comparison of German hospice with nonhospice volunteers revealed stronger differences: German hospice volunteers scored higher on altruistic motives, while German nonhospice volunteers yielded higher scores on self-serving motives. Findings contribute to improved understanding of volunteering motivation and of activating or retaining hospice volunteers. © The Author(s) 2014.

This review includes the latest findings based on experimental studies addressing sport-specific balance, an area of research that has grown dramatically in recent years. The main objectives of this work were to investigate the postural sway response to different forms of exercise under laboratory and sport-specific conditions, to examine how this effect can vary with expertise, and to provide examples of the association of impaired balance with sport performance and/or increasing risk of injury. In doing so, sports where body balance is one of the limiting factors of performance were analyzed. While there are no significant differences in postural stability between athletes of different specializations and physically active individuals during standing in a standard upright position (e.g., bipedal stance), they have a better ability to maintain balance in specific conditions (e.g., while standing on a narrow area of support). Differences in magnitude of balance impairment after specific exercises (rebound jumps, repeated rotations, etc.) and mainly in speed of its readjustment to baseline are also observed. Besides some evidence on an association of greater postural sway with the increasing risk of injuries, there are many myths related to the negative influence of impaired balance on sport performance. Though this may be true for shooting or archery, findings have shown that in many other sports, highly skilled athletes are able to perform successfully in spite of increased postural sway. These findings may contribute to better understanding of the postural control system under various performance requirements. It may provide useful knowledge for designing training programs for specific sports.

The aim of this study was to quantify and predict relationships between rating of perceived exertion (RPE) and GPS training-load (TL) variables in professional Australian football (AF) players using group and individualized modeling approaches. TL data (GPS and RPE) for 41 professional AF players were obtained over a period of 27 wk. A total of 2711 training observations were analyzed with a total of 66 ± 13 sessions/player (range 39-89). Separate generalized estimating equations (GEEs) and artificial-neural-network analyses (ANNs) were conducted to determine the ability to predict RPE from TL variables (ie, session distance, high-speed running [HSR], HSR %, m/min) on a group and individual basis. Prediction error for the individualized ANN (root-mean-square error [RMSE] 1.24 ± 0.41) was lower than the group ANN (RMSE 1.42 ± 0.44), individualized GEE (RMSE 1.58 ± 0.41), and group GEE (RMSE 1.85 ± 0.49). Both the GEE and ANN models determined session distance as the most important predictor of RPE. Furthermore, importance plots generated from the ANN revealed session distance as most predictive of RPE in 36 of the 41 players, whereas HSR was predictive of RPE in just 3 players and m/min was predictive of RPE in just 2 players. This study demonstrates that machine learning approaches may outperform more traditional methodologies with respect to predicting athlete responses to TL. These approaches enable further individualization of load monitoring, leading to more accurate training prescription and evaluation.
Full Text Available Sport with its emphasised efficiency component clearly reflects cognitive contents and the way they are linked to experience and behaviour. Beliefs, subjective judgements, attitudes, etc. define the attitude to sport, training, competition and results. Their contents can be defined by a psychological examination. We assess their meaning, appropriateness or inappropriateness. They can also be changed by using diverse cognitive-behavioural or reeducative procedures. Psychological work is carried out through systematic psychological preparation, crisis interventions and special psychological preparation within the framework of a training process. Cognitive forms of work represent a significant part of ideomotor, verbal, intellectual and situational training.

Athletes also demonstrated significant changes (p < 0.05 in muscle contractile properties, CK, and DOMS following the training program and after the recovery period. In contrast, CRP and urea remained unchanged throughout the study. Further analysis revealed that the accuracy of markers for assessment of fatigue and recovery in comparison to RSA derived from a contingency table was insufficient. Multiple regression analysis also showed no correlations between changes in RSA and any of the markers.Mean changes in measures of neuromuscular function, CK and DOMS are related to HIIT induced fatigue and subsequent recovery. However, low accuracy of a single or combined use of these markers requires the verification of their applicability on an individual basis.

Full Text Available As participation in both amateur and professional sports increases, so does the importance of sports performance and the factors influencing it. Determinants of success in sports can be classified as training, genetic, epigenetic, dietary, motivational, equipment and other environmental factors. The effect of genetics on sports performance and skill has been examined for many years. Autosomal genes, mitochondrial DNA and various genes located in the Y chromosome have all been associated with sports performance. It is not possible to link physical performance to a single genetic polymorphism. Genes that have been most extensively studied in their relation to performance include ACE, ACTN3, ADRA2A, ADRB2, PPARA, PPARGC1A, AMPD1, HIF1A, NOS3, BDKRB2, VEGFR2 and VEGFA. For the time being, genetic screening tests may be useful in determining the weaknesses and strengths of a sportsperson, but not in predicting athletic success.

Age-related degenerations in brain structure are associated with balance disturbances and cognitive impairment. However, neuroplasticity is known to be preserved throughout lifespan and physical training studies with seniors could reveal volume increases in the hippocampus (HC), a region crucial for memory consolidation, learning and navigation in space, which were related to improvements in aerobic fitness. Moreover, a positive correlation between left HC volume and balance performance was observed. Dancing seems a promising intervention for both improving balance and brain structure in the elderly. It combines aerobic fitness, sensorimotor skills and cognitive demands while at the same time the risk of injuries is low. Hence, the present investigation compared the effects of an 18-month dancing intervention and traditional health fitness training on volumes of hippocampal subfields and balance abilities. Before and after intervention, balance was evaluated using the Sensory Organization Test and HC volumes were derived from magnetic resonance images (3T, MP-RAGE). Fourteen members of the dance (67.21 ± 3.78 years, seven females), and 12 members of the fitness group (68.67 ± 2.57 years, five females) completed the whole study. Both groups revealed hippocampal volume increases mainly in the left HC (CA1, CA2, subiculum). The dancers showed additional increases in the left dentate gyrus and the right subiculum. Moreover, only the dancers achieved a significant increase in the balance composite score. Hence, dancing constitutes a promising candidate in counteracting the age-related decline in physical and mental abilities.

Increased youth participation in sports has resulted in increased injury tolls due to shifts toward participation in competitive sports at earlier ages, increased training intensity and competition schedules, as well as specialization into one sport. The physiology of the growing musculoskeletal system makes the growing athlete particularly vulnerable to specific types of injuries. Radiologists must understand the differences between pediatric and adult athletes to recognize the particular injuries to which these young athletes are prone. Imaging and pertinent clinical details of major representative acute and overuse injuries characteristic to pediatric athletes will be discussed. © RSNA, 2017.
Full Text Available This paper examines the learning experienced through participation by men in twoquite different two motor sports organisations in Western Australia. It relies oninterview data from volunteers about what they do and what they learn as aconsequence of their participation in staging complex but safe, competitive, publicevents.

Global Positioning Systems (GPS) are considered suitable to monitor the position and velocity of horses during cross-country competition or in training. Furthermore, simultaneous recording of life data such as heart rate could be useful to assess the horse's condition during exercise. To test the suitability and reliability of a commercially available GPS system with integrated heart rate recording system and with built in GSM for data transmission, the Fidelak Equipilot Type EP-2003-15/G-2.11 (EP-15/G) was evaluated first for reliability of pulse recording from a pulse generator within the physiological range of horses; furthermore distance, velocity and heart rate recordings were carried out on a standard 1000 m field track with five repetitions. Agreement (% deviation from actually measured distance and from stopwatch-distance based velocity calculations) and variability (Coefficient of Variation for distance, velocity, heart rate) were calculated. From the results it was safe to assume that the heart rate sensor recorded horse heart rates at a high degree of accuracy. Overall distances and velocities are in high agreement with actually measured values. However, overall variability expressed in terms of relative variability (C.V.) is smaller for distance recording (C.V. 0.68%) when compared to velocity (C.V. 1.01%). The system tested is suitable and reliable for simultaneously recording of distance, velocity and heart rates for horses during cross country exercise. GPS-based monitoring of movement along with simultaneous recording of physiological data and the possibility to call upon data will not only be of benefit for training horses or for surveillance during competition, it may also be suitable for distant patient monitoring and in behavioural studies as well as in veterinary medicine in general.

Athletes often are cleared to return to activities 6 months after anterior cruciate ligament (ACL) reconstruction; however, knee function measures continue to improve up to 2 years after surgery. Interventions beyond standard care may facilitate successful return to preinjury activities and improve functional outcomes. Perturbation training has been used in nonoperative ACL injury and preoperative ACL reconstruction rehabilitation, but has not been examined in postoperative ACL reconstruction rehabilitation, specifically return to sport rehabilitation. The purpose of this study was to determine whether there were differences at 1 and 2 years after ACL reconstruction between the male SAP (strengthening, agility, and secondary prevention) and SAP+PERT (SAP protocol with the addition of perturbation training) groups with respect to (1) quadriceps strength and single-legged hop limb symmetry; (2) patient-reported knee outcome scores; (3) the proportion who achieve self-reported normal knee function; and (4) the time from surgery to passing return to sport criteria. Forty men who had completed ACL reconstruction rehabilitation and met enrollment criteria (3-9 months after ACL reconstruction, > 80% quadriceps strength limb symmetry, no pain, full ROM, minimal effusion) were randomized into the SAP or SAP+PERT groups of the Anterior Cruciate Ligament-Specialised Post-Operative Return to Sports trial (ACL-SPORTS), a single-blind randomized clinical study of secondary prevention and return to sport. Quadriceps strength, single-legged hopping, the International Knee Documentation Committee (IKDC) 2000 subjective knee form, Knee Injury and Osteoarthritis Outcome Score (KOOS)-sports and recreation, and KOOS-quality-of-life subscales were collected 1 and 2 years after surgery by investigators blind to group. Athletes were categorized as having normal or abnormal knee function at each time point based on IKDC score, and the time until athletes passed strict return-to-sport

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 This article examines the history and characteristics of sport nationalism in South Korea as a step toward a comparative study in East Asia, with special emphasis on media, postcolonial history of the policies, and the ritual dimension of sport. The Korean government has sought triumphalism embodied by a focused strategy of close collaboration at the state and local levels, elitist training method, special rewards for athletes’ distinguished results, and so on. Nationwide enthusiasm promoted by media creates nationalistic solidarity. In postcolonial South Korea, sport has been used as a special tool to achieve focused political aims, such as prevailing against the anti-communist and anti-Japanese competitions. But recently, as the Korean society becomes more affluent and matured, people begin to enjoy the appeal of sport per se. The mega sport events, including public viewing, present a typical scene of Korean nationalistic enthusiasm, but it is also a good example of ritual consumption and the development of sport as art. To understand the vitality of sport in East Asia, it is important to notice the coexistence of the non-utilitarian aspect of sports with their political and ritual use.

To determine the time course for physical-capacity adaptations to intermittent hypoxic training (IHT) in team-sport athletes and the time course for benefits remaining after IHT. A pre-post parallel-groups design was employed, with 21 Australian footballers assigned to IHT (n = 10) or control (CON; n = 11) matched for training load. IHT performed eleven 40-min bike sessions at 2500-m altitude over 4 wk. Yo-Yo Intermittent Recovery Test level 2 (Yo-Yo IR2) was performed before; after 3, 6, and 11 IHT sessions; and 30 and 44 d after IHT. Repeated time trials (2- and 1-km TTs, with 5 min rest) were performed before, after, and 3 wk after IHT. Hemoglobin mass (Hb(mass)) was measured in IHT before and after 3, 6, 9, and 11 sessions. Baseline Yo-Yo IR2 was similar between groups. After 6 sessions, the change in Yo-Yo IR2 in IHT was very likely higher than CON (27% greater change, effect size 0.77, 90% confidence limits 0.20;1.33) and likely higher 1 d after IHT (23%, 0.68, 0.05;1.30). The IHT group's change remained likely higher than CON 30 d after IHT (24%, 0.72, 0.12;1.33) but was not meaningfully different 44 d after (12%, 0.36, -0.24;0.97). The change in 2-km TT performance between groups was not different throughout. For 1-km TT, CON improved more after IHT, but IHT maintained performance better after 3 wk. Hb(mass) was higher after IHT (2.7%, 0.40, -0.40;1.19). Short-duration IHT increased Yo-Yo IR2 compared with training-load-matched controls in 2 wk. An additional 2 wk of IHT provided no further benefit. These changes remained until at least 30 d posttraining. IHT also protected improvement in 1-km TT.

Over the past three decades, the world of both amateur and professional sports has expanded greatly and become more complex. In part related to these changes - and relatively unknown to sports medicine practitioners - the field of sport psychiatry has steadily evolved and grown. This paper focuses on what these changes have been. A sport psychiatrist is a physician-psychiatrist who diagnoses and treats problems, symptoms and/or disorders associated with an athlete, with their family/significant others, with their team, or with their sport, including spectators/fans. The primary aims of the specialty are to (i) optimize health, (ii) improve athletic performance, and (iii) manage psychiatric symptoms or disorders. The training includes medical training to provide knowledge and skills unique to physicians; psychiatric training to provide knowledge and skills inherent in that field, and training and/or experience in sport psychiatry to provide knowledge and skills about psychiatric aspects of sports. The sport psychiatrist first makes an individual, family-systems and phenomenological diagnosis of the clinical situation. Based on this evaluation, he sets goals for not only the athlete, but also for significant others involved. He delivers treatment based on the psychiatric disorder or problem using a combination of medication, psychotherapy or self-help group interventions plus strategies targeted to specific sport performance issues. Evolution of the International Society of Sport Psychiatry as well as the field, including incorporation into school and professional team sports, is described along with a 'typical day' for a sport psychiatrist. Case examples, a training curriculum and core literature are included.

Careful modulation of training characteristics in high-level sports optimizes performance and avoids inappropriate workloads and associated sports injury risk. The aims of this study were to compare sport participation characteristics in different youth sport categories and to investigate their relationship with injury. Prospective cohort follow-up. Young (12-19 years) high-level athletes (n=154) from a regional sport school were followed during 41 weeks regarding sport participation characteristics and traumatic and overuse sports injuries (time-loss definition). All data were self-recorded by the athletes in an electronic system "TIPPS" (Training and Injury Prevention Platform for Sports) and subject to a systematic data quality control. Volume and intensity (self-rated perceived exertion) of each sport session were used to compute weekly load, monotony and strain. Sport categories were defined as team, racket, and individual sports. All sport participation characteristics were dependent on sport category (psports were associated with lower injury risk (HR=0.37 and 0.34, p=0.001 and psports. Average sport participation characteristics were not related to injury according to the survival analysis. However, intensity during the week prior to injury was significantly higher (psport participation pattern and injury risk in young athletes. The monitoring method was sensitive to variations according to pertinent variables and might help identify athletes with increased sports injury risk. Copyright © 2013 Sports Medicine Australia.

Little effort has focused on the role of volunteer-led out-of-school time (OST) programs (ie, enrichment and sports programs) as key environments for the promotion of healthy eating and physical activity habits among school-aged children. The Healthy Kids Out of School (HKOS) initiative developed evidence-based, practical guiding principles for healthy snacks, beverages, and physical activity. The goal of this case study was to describe the methods used to engage regional partners to understand how successful implementation and dissemination of these principles could be accomplished. HKOS partnered with volunteer-led programs from 5 OST organizations in Maine, Massachusetts, and New Hampshire to create a regional "learning laboratory." We engaged partners in phases. In the first phase, we conducted focus groups with local volunteer program leaders; during the second phase, we held roundtable meetings with regional and state program administrators; and in the final phase, we conducted additional outreach to refine and finalize implementation strategies. Implementation strategies were developed based on themes and information that emerged. For enrichment programs, strategies included new patch and pin programs that were consistent with the organizations' infrastructure and usual practices. For sports programs, the main strategy was integration with online trainings for coaches. Through the engagement process, we learned that dissemination of the guiding principles in these large and complex OST organizations was best accomplished by using implementation strategies that were customized, integrated, and aligned with goals and usual practices. The lessons learned can benefit future efforts to prevent obesity in complex environments.

Anterior Cruciate Ligament (ACL) injury is an important cause of days lost in athletes. Most ACL injuries are non-contact and are associated with biomechanical risk factors that increase tension in the ACL: increased knee valgus (KV) and hip flexion (HF) and decreased flexion of knee (KF). Muscle around the knee contributes to knee stability, so fatigue produced by exercise could alter knee balance, increasing LCA tension. The aim of the study is to determine the angular behavior before and after a physical load for CF, RR and RV in children born in 2002-2003. A non-randomized clinical trial was conducted. The sample consisted of 50 students from soccer schools born between 2002 and 2003. The angular behavior of CF, RR and VR was compared, before and after performing standardized training. The angular behavior was measured by performing the DJ test with data obtained by inertial sensors. After exercise, the 3 variables increased, but only HF reached significant difference. Other important finding was the difference found in KV between the dominant leg and the support limb, at both times: rest and post exercise. It was concluded that the angular behavior of CF increases significantly in both limbs post-exercise and that preventive measures should be applied for the management of valgus in the supporting limb.
