    Laboratory analyses in sports medicine are relevant for three reasons: 1. In actively exercising individuals laboratory analysis are one of the central elements in the diagnosis of diseases and overreaching. 2. Regularly done laboratory analysis in competitive athletes with high load of training and competition may help to detect certain deficiencies early on. 3. Physical activity in general and competitive exercise training specifically do change certain routine laboratory parameters significantly although not reflecting pathological changes. These so-called preanalytic variations should be taken into consideration while interpreting laboratory data in medical emergency and routine diagnostics. This article intends to help the physician to interprete laboratory data of actively exercising sportsmen.

    Whilst in recent years the sociology of sport has taken to heart vociferous calls ‘to bring the body back in’ to analyses of sporting activity, the ‘promise of phenomenology’ signalled by Kerry and Armour (2000), remains under-realised with regard to sporting embodiment. Surprisingly, given the focus of study, relatively few accounts are truly grounded in the corporeal realities of the lived, sensuous sporting body. Phenomenology offers us a powerful framework for such analysis and has been a...

  3. The Technology to Train Techniques in Sports

    Full Text Available The training session of technical techniques is proposed to conduct on the playing ground where computer-controlled light emitters create allowed and unallowed light dynamic zones. Each athlete is to be placed in one of the allowed zones and to execute with an implement some techniques directed with his breast on the light guide mark created outside the allowed zone. The athlete holding an implement is not allowed to go out of the permitted area. In the course of the training session unpredictably for an athlete the position, the shape and the area of the permitted and unallowed zones is changed. The athlete’s going into the unallowed zone or performing techniques in the position not-oriented on the guide mark is considered to be an error. If the errors are none, the allowed zone area is reduced and the intensity of the session is increased until the athlete commits an error. By the minimum square of the allowed zone, the maximum speed of its movement that the athlete performing the exercise does not commit any errors, they evaluate the athlete’s technical skill. The proposed technology facilitates in faster mastering the play technique, unlocking the individual technical features and enhancing them at any stage of the professional career. The technology can be used for the technical training of athletes of different professional profiles specializing in football, hockey, handball, basketball and other sports that require implement handling.

    As increasing attention is paid to the cost of health care delivered in the United States (US), cost-effectiveness analyses (CEAs) are gaining in popularity. Reviews of the CEA literature have been performed in other areas of medicine, including some subspecialties within orthopaedics. Demonstrating the value of medical procedures is of utmost importance, yet very little is known about the overall quality and findings of CEAs in sports medicine. To identify and summarize CEA studies in orthopaedic sports medicine and to grade the quality of the available literature. Systematic review. A systematic review of the literature was performed to compile findings and grade the methodological quality of US-based CEA studies in sports medicine. The Quality of Health Economic Studies (QHES) instrument and the checklist by the US Panel on Cost-effectiveness in Health and Medicine were used to assess study quality. One-sided Fisher exact testing was performed to analyze the predictors of high-quality CEAs. Twelve studies met inclusion criteria. Five studies examined anterior cruciate ligament reconstruction, 3 studies examined rotator cuff repair, 2 examined autologous chondrocyte implantation, 1 study examined hip arthroscopic surgery, and 1 study examined the operative management of shoulder dislocations. Based on study findings, operative intervention in sports medicine is highly cost-effective. The quality of published evidence is good, with a mean quality score of 81.8 (range, 70-94). There is a trend toward higher quality in more recent publications. No significant predictor of high-quality evidence was found. The CEA literature in sports medicine is good; however, there is a paucity of studies, and the available evidence is focused on a few procedures. More work needs to be conducted to quantify the cost-effectiveness of different techniques and procedures within sports medicine. The QHES tool may be useful for the evaluation of future CEAs. © 2014 The Author(s).

    2013-01-01

    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.

  11. Team Sports Performance Analysed Through the Lens of Social Network Theory: Implications for Research and Practice.

    Science.gov (United States)

    Ribeiro, João; Silva, Pedro; Duarte, Ricardo; Davids, Keith; Garganta, Júlio

    2017-02-15

    This paper discusses how social network analyses and graph theory can be implemented in team sports performance analyses to evaluate individual (micro) and collective (macro) performance data, and how to use this information for designing practice tasks. Moreover, we briefly outline possible limitations of social network studies and provide suggestions for future research. Instead of cataloguing discrete events or player actions, it has been argued that researchers need to consider the synergistic interpersonal processes emerging between teammates in competitive performance environments. Theoretical assumptions on team coordination prompted the emergence of innovative, theoretically driven methods for assessing collective team sport behaviours. Here, we contribute to this theoretical and practical debate by re-conceptualising sports teams as complex social networks. From this perspective, players are viewed as network nodes, connected through relevant information variables (e.g. a ball-passing action), sustaining complex patterns of interaction between teammates (e.g. a ball-passing network). Specialised tools and metrics related to graph theory could be applied to evaluate structural and topological properties of interpersonal interactions of teammates, complementing more traditional analysis methods. This innovative methodology moves beyond the use of common notation analysis methods, providing a richer understanding of the complexity of interpersonal interactions sustaining collective team sports performance. The proposed approach provides practical applications for coaches, performance analysts, practitioners and researchers by establishing social network analyses as a useful approach for capturing the emergent properties of interactions between players in sports teams.

  14. Analysing CMS transfers using Machine Learning techniques

    CERN Document Server

    Diotalevi, Tommaso

    2016-01-01

    LHC experiments transfer more than 10 PB/week between all grid sites using the FTS transfer service. In particular, CMS manages almost 5 PB/week of FTS transfers with PhEDEx (Physics Experiment Data Export). FTS sends metrics about each transfer (e.g. transfer rate, duration, size) to a central HDFS storage at CERN. The work done during these three months, here as a Summer Student, involved the usage of ML techniques, using a CMS framework called DCAFPilot, to process this new data and generate predictions of transfer latencies on all links between Grid sites. This analysis will provide, as a future service, the necessary information in order to proactively identify and maybe fix latency issued transfer over the WLCG.

    Full Text Available In Genetic Algorithm (GA, the fitness or quality of individual solutions in the initial population plays a significant part in determining the final optimal solution. The traditional GA withrandom population seeding technique is simple and proficient however the generated population may contain poor fitness individuals, which take long time to converge to the optimal solution. On the otherhand, the hybrid population seeding techniques, which have the benefits of generating good fitness individuals and fast convergence to the optimal solution. Researchers have proposed several populationseeding techniques using the background knowledge on the problem taken to solve. In this paper, we analyse the performance of different population seeding techniques for the permutation coded genetic algorithm based on the quality of the individuals generated. Experiments are carried out using the famous Travelling Salesman Problem (TSP benchmark instances obtained from the TSPLIB, which isthe standard library for TSP problems. The experimental results show the order of performance of different population seeding techniques in terms of Convergence Rate (% and Error Rate (%.

  20. Central neuronal motor behaviour in skilled and less skilled novices - Approaching sports-specific movement techniques.

    Research on motor behavioural processes preceding voluntary movements often refers to analysing the readiness potential (RP). For this, decades of studies used laboratory setups with controlled sports-related actions. Further, recent applied approaches focus on athlete-non-athlete comparisons, omitting possible effects of training history on RP. However, RP preceding real sport-specific movements in accordance to skill acquisition remains to be elucidated. Therefore, after familiarization 16 right-handed males with no experience in archery volunteered to perform repeated sports-specific movements, i.e. 40 arrow-releasing shots at 60s rest on a 15m distant standard target. Continuous, synchronised EEG and right limb EMG recordings during arrow-releasing served to detect movement onsets for RP analyses over distinct cortical motor areas. Based on attained scores on target, archery novices were, a posteriori, subdivided into a skilled and less skilled group. EMG results for mean values revealed no significant changes (all p>0.05), whereas RP amplitudes and onsets differed between groups but not between motor areas. Arrow-releasing preceded larger RP amplitudes (p<0.05) and later RP onsets (p<0.05) in skilled compared to less skilled novices. We suggest this to reflect attentional orienting and greater effort that accompanies central neuronal preparatory states of a sports-specific movement.

  1. Statistical technique for analysing functional connectivity of multiple spike trains.

    Masud, Mohammad Shahed; Borisyuk, Roman

    2011-03-15

    A new statistical technique, the Cox method, used for analysing functional connectivity of simultaneously recorded multiple spike trains is presented. This method is based on the theory of modulated renewal processes and it estimates a vector of influence strengths from multiple spike trains (called reference trains) to the selected (target) spike train. Selecting another target spike train and repeating the calculation of the influence strengths from the reference spike trains enables researchers to find all functional connections among multiple spike trains. In order to study functional connectivity an "influence function" is identified. This function recognises the specificity of neuronal interactions and reflects the dynamics of postsynaptic potential. In comparison to existing techniques, the Cox method has the following advantages: it does not use bins (binless method); it is applicable to cases where the sample size is small; it is sufficiently sensitive such that it estimates weak influences; it supports the simultaneous analysis of multiple influences; it is able to identify a correct connectivity scheme in difficult cases of "common source" or "indirect" connectivity. The Cox method has been thoroughly tested using multiple sets of data generated by the neural network model of the leaky integrate and fire neurons with a prescribed architecture of connections. The results suggest that this method is highly successful for analysing functional connectivity of simultaneously recorded multiple spike trains.

  2. The role of ecological dynamics in analysing performance in team sports.

    2012-01-01

    Performance analysis is a subdiscipline of sports sciences and one-approach, notational analysis, has been used to objectively audit and describe behaviours of performers during different subphases of play, providing additional information for practitioners to improve future sports performance. Recent criticisms of these methods have suggested the need for a sound theoretical rationale to explain performance behaviours, not just describe them. The aim of this article was to show how ecological dynamics provides a valid theoretical explanation of performance in team sports by explaining the formation of successful and unsuccessful patterns of play, based on symmetry-breaking processes emerging from functional interactions between players and the performance environment. We offer the view that ecological dynamics is an upgrade to more operational methods of performance analysis that merely document statistics of competitive performance. In support of our arguments, we refer to exemplar data on competitive performance in team sports that have revealed functional interpersonal interactions between attackers and defenders, based on variations in the spatial positioning of performers relative to each other in critical performance areas, such as the scoring zones. Implications of this perspective are also considered for practice task design and sport development programmes.

  3. Requirements Analyses Integrating Goals and Problem Analysis Techniques

    2007-01-01

    One of the difficulties that goal-oriented requirements analyses encounters is that the efficiency of the goal refinement is based on the analysts' subjective knowledge and experience. To improve the efficiency of the requirements eiicitation process, engineers need approaches with more systemized analysis techniques. This paper integrates the goal-oriented requirements language i* with concepts from a structured problem analysis notation, problem frames (PF). The PF approach analyzes software design as a contextualized problem which has to respond to constraints imposed by the environment. The proposed approach is illustrated using the meeting scheduler exemplar. Results show that integration of the goal and the problem analysis enables simultaneous consideration of the designer's subjective intentions and the physical environmental constraints.

    Short peak rainfall intensities cause sewer systems to overflow leading to flooding of streets and houses. Due to climate change and densification of urban areas, this is expected to occur more often in the future. Hence, next to their minor (i.e. sewer) system, municipalities have to analyse their major (i.e. surface) system in order to anticipate urban flooding during extreme rainfall. Urban flood modelling techniques are powerful tools in both public and internal communications and transparently support design processes. To provide more insight into the (im)possibilities of different urban flood modelling techniques, simulation results have been compared for an extreme rainfall event. The results show that, although modelling software is tending to evolve towards coupled one-dimensional (1D)-two-dimensional (2D) simulation models, surface flow models, using an accurate digital elevation model, prove to be an easy and fast alternative to identify vulnerable locations in hilly and flat areas. In areas at the transition between hilly and flat, however, coupled 1D-2D simulation models give better results since catchments of major and minor systems can differ strongly in these areas. During the decision making process, surface flow models can provide a first insight that can be complemented with complex simulation models for critical locations.

  5. Promoting Social Inclusion through Sport for Refugee-Background Youth in Australia: Analysing Different Participation Models

    2017-06-01

    Full Text Available Sports participation can confer a range of physical and psychosocial benefits and, for refugee and migrant youth, may even act as a critical mediator for achieving positive settlement and engaging meaningfully in Australian society. This group has low participation rates however, with identified barriers including costs; discrimination and a lack of cultural sensitivity in sporting environments; lack of knowledge of mainstream sports services on the part of refugee-background settlers; inadequate access to transport; culturally determined gender norms; and family attitudes. Organisations in various sectors have devised programs and strategies for addressing these participation barriers. In many cases however, these responses appear to be ad hoc and under-theorised. This article reports findings from a qualitative exploratory study conducted in a range of settings to examine the benefits, challenges and shortcomings associated with different participation models. Interview participants were drawn from non-government organisations, local governments, schools, and sports clubs. Three distinct models of participation were identified, including short term programs for refugee-background children; ongoing programs for refugee-background children and youth; and integration into mainstream clubs. These models are discussed in terms of their relative challenges and benefits and their capacity to promote sustainable engagement and social inclusion for this population group.

  7. Techniques for analyses of trends in GRUAN data

    Directory of Open Access Journals (Sweden)

    G. E. Bodeker

    2014-12-01

    Full Text Available The Global Climate Observing System (GCOS Reference Upper Air Network (GRUAN provides reference quality RS92 radiosonde measurements of temperature, pressure and humidity. A key attribute of reference quality measurements, and hence GRUAN data, is that each datum has a well characterised and traceable estimate of the measurement uncertainty. The long-term homogeneity of the measurement records, and their well characterised uncertainties, make these data suitable for reliably detecting changes in global and regional climate on decadal time scales. Considerable effort is invested in GRUAN operations to (i describe and analyse all sources of measurement uncertainty to the extent possible, (ii quantify and synthesize the contribution of each source of uncertainty to the total measurement uncertainty, and (iii verify that the evaluated net uncertainty is within the required target uncertainty. However, if the climate science community is not sufficiently well informed on how to capitalize on this added value, the significant investment in estimating meaningful measurement uncertainties is largely wasted. This paper presents and discusses the techniques that will need to be employed to reliably quantify long-term trends in GRUAN data records. A pedagogical approach is taken whereby numerical recipes for key parts of the trend analysis process are explored. The paper discusses the construction of linear least squares regression models for trend analysis, boot-strapping approaches to determine uncertainties in trends, dealing with the combined effects of autocorrelation in the data and measurement uncertainties in calculating the uncertainty on trends, best practice for determining seasonality in trends, how to deal with co-linear basis functions, and interpreting derived trends. Synthetic data sets are used to demonstrate these concepts which are then applied to a first analysis of temperature trends in RS92 radiosonde upper air soundings at the GRUAN

  8. Split Hopkinson pressure bar technique: Experiments, analyses and applications

    Science.gov (United States)

    Gama, Bazle Anwer

    A critical review of the Hopkinson bar experimental technique is performed to identify the validity and applicability of the classic one-dimensional theory. A finite element model of the Hopkinson bar experiment is developed in three-dimensions and is used in detailed numerical analyses. For a small diameter hard specimen, the bar-specimen interfaces are non-planar, which predicts higher specimen strain and, thus, lower initial modulus in the linear elastic phase of deformation. In such cases, the stress distribution in the specimen is not uni-axial and a chamfered specimen geometry is found to provide better uni-axial stress condition in the specimen. In addition, a new Hopkinson bar with transmission tube is found suitable for small strain measurement of small diameter specimens. A one-dimensional exact Hopkinson bar theory considering the stress wave propagation in an equal diameter specimen has been formulated which predicts physically meaningful results in all extreme cases as compared to classic theory. In light of the theoretical and numerical investigations, an experimental methodology for rate dependent modulus and strength is developed. Quasi-static and dynamic behavior of plain weave (15 x 15) S-2 glass/SC15 composites has been investigated. A new circular-rectangular prism specimen (C-RPS) geometry is found suitable for testing laminated composites in the in-plane directions. Rate sensitive strength, non-linear strain and elastic modulus parameters for plain-weave (15 x 15) S-2 glass/SC15 composites have been experimentally determined.

    Kay, Richard G; Creaser, Colin S

    2010-04-01

    Mass spectrometry-based proteomic approaches have been used to develop methodologies capable of detecting the abuse of protein therapeutics such as recombinant human erythropoietin and recombinant human growth hormone. Existing detection methods use antibody-based approaches that, although effective, suffer from long assay development times and specificity issues. The application of liquid chromatography with tandem mass spectrometry and selected reaction-monitoring-based analysis has demonstrated the ability to detect and quantify existing protein therapeutics in plasma. Furthermore, the multiplexing capability of selected reaction-monitoring analysis has also aided in the detection of multiple downstream biomarkers in a single analysis, requiring less sample than existing immunological techniques. The flexibility of mass spectrometric instrumentation has shown that the technique is capable of detecting the abuse of novel and existing protein therapeutics, and has a vital role in the fight to keep sports drug-free.

    DNA fingerprinting is a genetic typing technique that allows the analysis of the genomic relatedness between samples, and the comparison of DNA patterns. The analysis of DNA gel fingerprint images usually consists of five consecutive steps: image pre-processing, lane segmentation, band detection, normalization and fingerprint comparison. In this article, we firstly survey the main methods that have been applied in the literature in each of these stages. Secondly, we focus on lane-segmentation and band-detection algorithms-as they are the steps that usually require user-intervention-and detect the seven core algorithms used for both tasks. Subsequently, we present a benchmark that includes a data set of images, the gold standards associated with those images and the tools to measure the performance of lane-segmentation and band-detection algorithms. Finally, we implement the core algorithms used both for lane segmentation and band detection, and evaluate their performance using our benchmark. As a conclusion of that study, we obtain that the average profile algorithm is the best starting point for lane segmentation and band detection.

    The applications of ultrasound in managing the clinical care of athletes have been expanding over the past decade. This review provides an analysis of the research that has been published regarding the use of ultrasound in athletes and focuses on how these emerging techniques can impact the clinical management of athletes by sports medicine physicians. Electronic database literature searches were performed using the subject terms 'ultrasound' and 'athletes' from the years 2003 to 2012. The following databases were searched: PubMed, Web of Science, Cochrane Library, CINAHL, and SPORTDiscus™. The search produced 617 articles in total, with a predominance of articles focused on cardiac and musculoskeletal ultrasound. 266 of the studies involved application of ultrasound in evaluating the cardiovascular properties of athletes, and 151 studies involved musculoskeletal ultrasound. Other applications of ultrasound included abdominal, vascular, bone density and volume status. New techniques in echocardiography have made significant contributions to the understanding of the physiological changes that occur in the athlete's heart in response to the haemodynamic stress associated with different types of activity. The likely application of these techniques will be in managing athletes with hypertrophic cardiomyopathy, and the techniques are near ready for application into clinical practice. These techniques are highly specialized, however, and will require referral to dedicated laboratories to influence the clinical management of athletes. Investigation of aortic root pathology and pulmonary vascular haemodynamics are also emerging, but will require additional studies with larger numbers and outcomes analysis to validate their clinical utility. Some of these techniques are relatively simple, and thus hold the potential to enter clinical management in a point-of-care fashion. Musculoskeletal ultrasound has demonstrated a number of diagnostic and therapeutic techniques

    2016-03-01

    To investigate on-ice repeated-sprint and sports-specific-technique abilities and the relationships to aerobic and anaerobic off-ice capacities in world-class ice sledge hockey players. Twelve Norwegian national team players performed 8 repeated maximal 30-m sprints and a sports-specific-technique test while upper-body poling on ice, followed by 4 maximal upper-body strength tests and 8-s peak power and 3-min peak aerobic-capacity (VO2peak) tests while ergometer poling. The fastest 30-m sprint time was 6.5 ± 0.4 s, the fastest initial 10-m split-time 2.9 ± 0.2 s, and the corresponding power output 212 ± 37 W. Average 30-m time during the 8 repeated sprints was 6.7 ± 0.4 s, and the sprint-time decrement was 4.3% ± 1.8%. Time to execute the sport-specific-technique test was 25.6 ± 2.7 s. Averaged 1-repetition-maximum strength of the 4 exercises correlated with the fastest 30-m sprint time (r = -.77), the fastest initial 10-m split time (r = -.72), the corresponding power output (r = .67), and the average 30-m sprint time (r = -.84) (all P sprint test correlated with the highest initial 10-m power (r = .83, P sprint time (r = -.68, P sprint-time decrement. All off-ice variables except VO2peak correlated with technique-test time (r = -.58 to .73, all P ability to sprint fast and rapid execution of a technically complex test, whereas mode-specific endurance capacity is particularly important for maintenance of sprint ability in ice sledge hockey.

    2016-06-01

    The main novelty of this paper is presenting the adaptation of Gesture Description Language (GDL) methodology to sport and rehabilitation data analysis and classification. In this paper we showed that Lua language can be successfully used for adaptation of the GDL classifier to those tasks. The newly applied scripting language allows easily extension and integration of classifier with other software technologies and applications. The obtained execution speed allows using the methodology in the real-time motion capture data processing where capturing frequency differs from 100 Hz to even 500 Hz depending on number of features or classes to be calculated and recognized. Due to this fact the proposed methodology can be used to the high-end motion capture system. We anticipate that using novel, efficient and effective method will highly help both sport trainers and physiotherapist in they practice. The proposed approach can be directly applied to motion capture data kinematics analysis (evaluation of motion without regard to the forces that cause that motion). The ability to apply pattern recognition methods for GDL description can be utilized in virtual reality environment and used for sport training or rehabilitation treatment.

    The discrimination between therapeutic and abusive use of drugs in sports is performed using threshold concentrations or reporting levels, and the detection of the substances in a sample is only reported as an adverse analytical finding when the concentration exceeds the threshold or the reporting level. In this paper, the strategies of discrimination and the analytical methods used for the main groups of substances where the distinction is needed (β-2 agonists, ephedrines, glucocorticoids and morphine) will be reviewed. Nowadays, LC-MS is the method of choice for the analysis of these substances and, in most of the cases, a simple dilution of the urine sample is performed before the chromatographic analysis.

  11. Application of digital-image-correlation techniques in analysing cracked cylindrical pipes

    Shih-Heng Tung; Chung-Huan Sui

    2010-10-01

    Cracks induced by external excitation on a material that has defects may generate the stress concentration phenomenon. The stress concentration behaviour causes local buckling, which will induce the damage of the members made of this material. Thus, developing techniques to monitor the strain variation of a cracked member is an important study. The traditional technique (such as strain gauge) can only measure the average strain of a region. The strain variation within this region cannot be determined. Therefore, it cannot sufficiently reflect the mechanical behaviour surrounding the crack. The Digital image correlation technique recently developed is an image identification technique to be applied for measuring the object deformation. This technique is capable of correlating the digital images of an object before and after deformation and further determining the displacement and strain field of an object based on the corresponding position on the image. In this work, this technique is applied to analyse the mechanics of a cylindrical pipe experiencing crack destruction. The fixing device is used to avoid shaking the specimen during the pressurizing process. The image capture instruments are fixed on the stable frame to measure the deformation of specimen accurately. Through the cylindrical pipe cracking test, the capacity of the digital image correlation technique for surveying the strain variation in a tiny region is validated. Then, the experimental results obtained using the digital image correlation analysis is used to demonstrate the crack development tendency in defect materials and the stress concentration zone.

    The mechanisms for speed performance improvement from sprint training and plyometrics training, especially relating to stance kinetics, require investigation in field sport athletes. This study determined the effects of sprint training and plyometrics training on 10-m sprint time (0-5, 5-10, and 0-10 m intervals), step kinematics (step length and frequency, contact and flight time), and stance kinetics (first, second, and last contact relative vertical [VF, VI], horizontal [HF, HI], and resultant [RF, RI] force and impulse; resultant ground reaction force angle [RFθ]; ratio of horizontal to resultant force [RatF]) during a 10-m sprint. Sixteen male field sport athletes were allocated into sprint training (ST) and plyometrics training (PT) groups according to 10-m sprint time; independent samples t-tests (p ≤ 0.05) indicated no between-group differences. Training involved 2 sessions per week for 6 weeks. A repeated measures analysis of variance (p ≤ 0.05) determined within- and between-subject differences. Both groups decreased 0-5 and 0-10 m time. The ST group increased step length by ∼15%, which tended to be greater than step length gains for the PT group (∼7%). The ST group reduced first and second contact RFθ and RatF, and second contact HF. Second contact HI decreased for both groups. Results indicated a higher post-training emphasis on VF production. Vertical force changes were more pronounced for the PT group for the last contact, who increased or maintained last contact VI, RF, and RI to a greater extent than the ST group. Sprint and plyometrics training can improve acceleration, primarily through increased step length and a greater emphasis on VF.

    A majority of sports science research is undertaken in universities and dedicated research centres, such as institutes of sport. Reviews of literature analysing and categorising research have been carried out, but categories identified have been limited to research design and data gathering techniques. Hence there is a need to include categories such as discipline, subjects and targeted sport. A study was conducted using document analysis method to gather data that described and categorised performance-based sports science research projects in Australian universities and institutes of sport. An instrument was designed that could be used by researchers to analyse and profile research in the area of sports science. The instrument contained six categories: targeted sport, primary study area, participant type, research setting, methodology and data gathering techniques. Research documents analysed consisted of 725 original unpublished research reports/theses. Results showed that over two-thirds of research projects were targeted to specific sports and, of this group, nearly half involved four sports: cycling, rowing, athletics and swimming. Overall, physiology was the most researched scientific discipline. The most frequently used research method was experimental design, and the most frequently used data gathering technique was physiological (performance) measures. Two-thirds of research was conducted in laboratory settings, and nearly half of the research was conducted with elite or sub-elite athletes as participants/subjects. The findings of this study provide an overall synopsis of performance-based sports science research conducted in Australia over the last 20 years, and should be of considerable importance in the ongoing development of sports science research policy in Australia.

    2017-04-01

    Short-term ocean analyses for Sea Surface Temperature SST in the Mediterranean Sea can be improved by a statistical post-processing technique, called super-ensemble. This technique consists in a multi-linear regression algorithm applied to a Multi-Physics Multi-Model Super-Ensemble (MMSE) dataset, a collection of different operational forecasting analyses together with ad-hoc simulations produced by modifying selected numerical model parameterizations. A new linear regression algorithm based on Empirical Orthogonal Function filtering techniques is capable to prevent overfitting problems, even if best performances are achieved when we add correlation to the super-ensemble structure using a simple spatial filter applied after the linear regression. Our outcomes show that super-ensemble performances depend on the selection of an unbiased operator and the length of the learning period, but the quality of the generating MMSE dataset has the largest impact on the MMSE analysis Root Mean Square Error (RMSE) evaluated with respect to observed satellite SST. Lower RMSE analysis estimates result from the following choices: 15 days training period, an overconfident MMSE dataset (a subset with the higher quality ensemble members), and the least square algorithm being filtered a posteriori.

    Full Text Available The misalignment in the orbital angular momentum- (OAM- based system would distort the radiation patterns of twisted beams carrying OAM, consequently making the OAM-based communication infeasible. To tackle the misalignment problem, a radio OAM steering technique based on a uniform circular array (UCA is illustrated. Subsequently, simulations are conducted to explore the influence of the OAM steering on the OAM mode quality and transmission performance. Furthermore, UCAs working at Ka-band with formulated feeding networks are designed and fabricated to analyze the performance of the OAM steering. The influences of OAM steering on mode quality and orthogonality are then evaluated in the experiment. Overall, the analyses of OAM steering technique are beneficial for the development of radio OAM study.

    This article describes the utilisation of an unsupervised machine learning technique and statistical approaches (e.g., the Kolmogorov-Smirnov test) that assist cycling experts in the crucial decision-making processes for athlete selection, training, and strategic planning in the track cycling Omnium. The Omnium is a multi-event competition that will be included in the summer Olympic Games for the first time in 2012. Presently, selectors and cycling coaches make decisions based on experience and intuition. They rarely have access to objective data. We analysed both the old five-event (first raced internationally in 2007) and new six-event (first raced internationally in 2011) Omniums and found that the addition of the elimination race component to the Omnium has, contrary to expectations, not favoured track endurance riders. We analysed the Omnium data and also determined the inter-relationships between different individual events as well as between those events and the final standings of riders. In further analysis, we found that there is no maximum ranking (poorest performance) in each individual event that riders can afford whilst still winning a medal. We also found the required times for riders to finish the timed components that are necessary for medal winning. The results of this study consider the scoring system of the Omnium and inform decision-making toward successful participation in future major Omnium competitions.

    The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player's technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13-18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual's overall skill - as well as their performance in their best task - was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.

    This work aims to discriminate among different species of the genus Cistus, using seed parameters and following the scientific plant names included as accepted in The Plant List. Also, the intraspecific phenotypic differentiation of C. creticus, through comparison with three subspecies (C. creticus subsp. creticus, C. c. subsp. eriocephalus and C. c. subsp. corsicus), as well as the interpopulation variability among five C. creticus subsp. eriocephalus populations was evaluated. Seed mean weight and 137 morphocolorimetric quantitative variables, describing shape, size, colour and textural seed traits, were measured using image analysis techniques. Measured data were analysed applying step-wise linear discriminant analysis. An overall cross-validated classification performance of 80.6% was recorded at species level. With regard to C. creticus, as case study, percentages of correct discrimination of 96.7% and 99.6% were achieved at intraspecific and interpopulation levels, respectively. In this classification model, the relevance of the colorimetric and textural descriptive features was highlighted, as well as the seed mean weight, which was the most discriminant feature at specific and intraspecific level. These achievements proved the ability of the image analysis system as highly diagnostic for systematic purposes and confirm that seeds in the genus Cistus have important diagnostic value. © 2016 German Botanical Society and The Royal Botanical Society of the Netherlands.

  16. The totally extraperitoneal method versus Lichtenstein's technique for inguinal hernia repair: a systematic review with meta-analyses and trial sequential analyses of randomized clinical trials.

    Directory of Open Access Journals (Sweden)

    G G Koning

    Full Text Available BACKGROUND: Lichtenstein's technique is considered the reference technique for inguinal hernia repair. Recent trials suggest that the totally extraperitoneal (TEP technique may lead to reduced proportions of chronic pain. A systematic review evaluating the benefits and harms of the TEP compared with Lichtenstein's technique is needed. METHODOLOGY/PRINCIPAL FINDINGS: The review was performed according to the 'Cochrane Handbook for Systematic Reviews'. Searches were conducted until January 2012. Patients with primary uni- or bilateral inguinal hernias were included. Only trials randomising patients to TEP and Lichtenstein were included. Bias evaluation and trial sequential analysis (TSA were performed. The error matrix was constructed to minimise the risk of systematic and random errors. Thirteen trials randomized 5404 patients. There was no significant effect of the TEP compared with the Lichtenstein on the number of patients with chronic pain in a random-effects model risk ratio (RR 0.80; 95% confidence interval (CI 0.61 to 1.04; p = 0.09. There was also no significant effect on number of patients with recurrences in a random-effects model (RR 1.41; 95% CI 0.72 to 2.78; p = 0.32 and the TEP technique may or may not be associated with less severe adverse events (random-effects model RR 0.91; 95% CI 0.73 to 1.12; p = 0.37. TSA showed that the required information size was far from being reached for patient important outcomes. CONCLUSIONS/SIGNIFICANCE: TEP versus Lichtenstein for inguinal hernia repair has been evaluated by 13 trials with high risk of bias. The review with meta-analyses, TSA and error matrix approach shows no conclusive evidence of a difference between TEP and Lichtenstein on the primary outcomes chronic pain, recurrences, and severe adverse events.

    We developed an approach for analysing the effects of two crossed factors A and B on the functional, taxonomic or phylogenetic composition of communities. The methodology, known as crossed-DPCoA, defines a space where species, communities and the levels of the two factors are organised as a set of points. In this space, the Euclidean distance between two species-specific points is a measure of the (functional, taxonomic or phylogenetic) dissimilarity. The communities are positioned at the centroid of their constitutive species; and the levels of two factors at the centroid of the communities associated with them. We develop two versions for crossed-DPCoA, the first one moves the levels of factor B to the centre of the space and analyses the axes of highest variance in the coordinates of the levels of factor A. It is related to previous ordination approaches such as partial canonical correspondence analysis and partial non-symmetrical correspondence analysis. The second version projects all points on the orthogonal complement of the space generated by the principal axes of factor B. This second version should be preferred when there is an a priori suspicion that factor A and B are associated. We apply the two versions of crossed-DPCoA to analyse the phylogenetic composition of Central European and Mediterranean bird communities. Applying crossed-DPCoA on bird communities supports the hypothesis that allopatric speciation processes during the Quaternary occurred in open and patchily distributed landscapes, while the lack of geographic barriers to dispersal among forest habitats may explain the homogeneity of forest bird communities over the whole western Palaearctic. Generalizing several ordination analyses commonly used in ecology, crossed-DPCoA provides an approach for analysing the effects of crossed factors on functional, taxonomic and phylogenetic diversity, environmental and geographic structure of species niches, and more broadly the role of genetics on

  6. Partial differential equation techniques for analysing animal movement: A comparison of different methods.

    Wang, Yi-Shan; Potts, Jonathan R

    2017-03-07

    Recent advances in animal tracking have allowed us to uncover the drivers of movement in unprecedented detail. This has enabled modellers to construct ever more realistic models of animal movement, which aid in uncovering detailed patterns of space use in animal populations. Partial differential equations (PDEs) provide a popular tool for mathematically analysing such models. However, their construction often relies on simplifying assumptions which may greatly affect the model outcomes. Here, we analyse the effect of various PDE approximations on the analysis of some simple movement models, including a biased random walk, central-place foraging processes and movement in heterogeneous landscapes. Perhaps the most commonly-used PDE method dates back to a seminal paper of Patlak from 1953. However, our results show that this can be a very poor approximation in even quite simple models. On the other hand, more recent methods, based on transport equation formalisms, can provide more accurate results, as long as the kernel describing the animal's movement is sufficiently smooth. When the movement kernel is not smooth, we show that both the older and newer methods can lead to quantitatively misleading results. Our detailed analysis will aid future researchers in the appropriate choice of PDE approximation for analysing models of animal movement. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The aims were to evaluate the effects of different additives on the adaptation of mineral trioxide aggregate (MTA) plugs before and after different backfilling techniques and analyze the interference of filling procedures on the fracture resistance of simulated immature teeth. The apical parts of 60 teeth were filled with MTA mixed with distilled water (DW), propylene glycol (PG) or calcium chloride (CaCl2) and backfilled with cold lateral condensation (CLC) or warm vertical compaction (WVC). The specimens were subjected to adaptation analysis and fracture testing. CaCl2 addition resulted in poor marginal adaptation, while PG addition significantly decreased the fracture values (pMTA-CaCl2 plugs and decreased the fracture values of teeth with MTA-PG plugs (pMTA with DW can be recommended as apical plug when the remaining root canal space is going to be filled with either CLC or WVC techniques.

    2012-12-01

    This paper provides an overview of the ethical issues pertaining to the use of genetic insights and techniques in sport. Initially, it considers a range of scientific findings that have stimulated debate about the ethical issues associated with genetics applied to sport. It also outlines some of the early policy responses to these discoveries from world leading sports organizations, along with knowledge about actual use of gene technologies in sport. Subsequently, it considers the challenges with distinguishing between therapeutic use and human enhancement within genetic science, which is a particularly important issue for the world of sport. Next, particular attention is given to the use of genetic information, which raises questions about the legitimacy and reliability of genetic tests, along with the potential public value of having DNA databanks to economize in health care. Finally, the ethics of gene transfer are considered, inviting questions into the values of sport and humanity. It argues that, while gene modification may seem conceptually similar to other forms of doping, the requirements upon athletes are such that new forms of enhancement become increasingly necessary to discover. Insofar as genetic science is able to create safer, more effective techniques of human modification, then it may be an appealing route through which to modify athletes to safeguard the future of elite sports as enterprises of human excellence.

  9. Analyses of Effects of Cutting Parameters on Cutting Edge Temperature Using Inverse Heat Conduction Technique

    Directory of Open Access Journals (Sweden)

    Marcelo Ribeiro dos Santos

    2014-01-01

    Full Text Available During machining energy is transformed into heat due to plastic deformation of the workpiece surface and friction between tool and workpiece. High temperatures are generated in the region of the cutting edge, which have a very important influence on wear rate of the cutting tool and on tool life. This work proposes the estimation of heat flux at the chip-tool interface using inverse techniques. Factors which influence the temperature distribution at the AISI M32C high speed steel tool rake face during machining of a ABNT 12L14 steel workpiece were also investigated. The temperature distribution was predicted using finite volume elements. A transient 3D numerical code using irregular and nonstaggered mesh was developed to solve the nonlinear heat diffusion equation. To validate the software, experimental tests were made. The inverse problem was solved using the function specification method. Heat fluxes at the tool-workpiece interface were estimated using inverse problems techniques and experimental temperatures. Tests were performed to study the effect of cutting parameters on cutting edge temperature. The results were compared with those of the tool-work thermocouple technique and a fair agreement was obtained.

  10. Techniques useful in two-dimensional correlation and codistribution spectroscopy (2DCOS and 2DCDS) analyses

    Science.gov (United States)

    Noda, Isao

    2016-11-01

    Certain techniques useful in enhancing the features of two-dimensional correlation and codistribution spectra (2DCOS and 2DCDS) are reviewed. 2DCOS sorts out the coordinated or sequential variations of spectral intensities induced by an external perturbation applied to a sample system. 2DCDS is designed to determine the order of the presence of individual species. Pareto scaling of data helps to regulate overwhelmingly strong signal contributions, which may obscure the fine features of 2DCOS and 2DCDS spectra. Pearson unit-variance scaling has some limitations by itself but is useful in some applications. Modified forms of asynchronous 2D spectrum combine the features of both synchronous and asynchronous spectra and can be used as a stand-alone 2D map for the streamlined determination of the sequential order of spectral intensity variations. Null-space projection simplifies congested 2D spectra by eliminating select features, such as contribution from a specific component. Node attenuation is a band narrowing technique suitable for 2D analysis, because it does not produce opposite-sign side lobes. Performance of each technique in enhancing the features of 2D spectra is demonstrated with a model set of experimental spectra.

  11. Wavelet-based spatial comparison technique for analysing and evaluating two-dimensional geophysical model fields

    Directory of Open Access Journals (Sweden)

    S. Saux Picart

    2011-11-01

    Full Text Available Complex numerical models of the Earth's environment, based around 3-D or 4-D time and space domains are routinely used for applications including climate predictions, weather forecasts, fishery management and environmental impact assessments. Quantitatively assessing the ability of these models to accurately reproduce geographical patterns at a range of spatial and temporal scales has always been a difficult problem to address. However, this is crucial if we are to rely on these models for decision making. Satellite data are potentially the only observational dataset able to cover the large spatial domains analysed by many types of geophysical models. Consequently optical wavelength satellite data is beginning to be used to evaluate model hindcast fields of terrestrial and marine environments. However, these satellite data invariably contain regions of occluded or missing data due to clouds, further complicating or impacting on any comparisons with the model. A methodology has recently been developed to evaluate precipitation forecasts using radar observations. It allows model skill to be evaluated at a range of spatial scales and rain intensities. Here we extend the original method to allow its generic application to a range of continuous and discontinuous geophysical data fields, and therefore allowing its use with optical satellite data. This is achieved through two major improvements to the original method: (i all thresholds are determined based on the statistical distribution of the input data, so no a priori knowledge about the model fields being analysed is required and (ii occluded data can be analysed without impacting on the metric results. The method can be used to assess a model's ability to simulate geographical patterns over a range of spatial scales. We illustrate how the method provides a compact and concise way of visualising the degree of agreement between spatial features in two datasets. The application of the new method, its

    Full Text Available Prior value studies in sport settings have been focused on participation rather than spectatorship. This study is an initial step in examining the values associated with spectator sports. Interviews and focus groups were utilized in this qualitative study within four progressive phases for triangulation, transferability, and constant comparative assessment. A total of 54 individuals participated in the study. Because values were subjectively perceived at the highest level of abstraction reflecting desirable preference experiences, the interviews were designed to include seven categories of questions: Three categories dealt with observed behaviors and implied metaphors, and four categories including questions comparing spectator sports and sport participation, religion, other leisure activities, and substitutes. Grounded data techniques guided the coding procedure. Using the transcriptions and notes from 26 interviews and three focus groups, five coders were used to provide evidence of interrater reliability. Based on the results of the data analyses, a 10-value-type framework was developed in relation to spectator sports: (a Enjoyment (pleasure and satisfaction, (b Sociability (social interaction through sport spectating, (c Identity (enhancing self-esteem, (d Status (pursuing social recognition, (e Moral, (f Spirituality (inner peace, strength, meaning, and purpose in life, (g Epistemic, (h Aesthetics, (i Ritual (sports spectating becomes a series of formal and serious acts followed regularly and invariably as end-experience, and (j no or negative values. Different from Kahle’s (1983, Maslow’s (1970a, and Schwartz’ (1992 value theories, the framework was specifically associated with spectator sports and is expected to better predict spectator sport behavior than does a scale measuring motivations of sports fans.

    A new flow analysis paradigm and a novel technique to enhance scarfed nozzle thrust are presented. The new paradigm, the space-time Conservation Element and Solution Element (CESE) method, a truly unsteady and genuinely multi-dimensional flow solver that provides accurate solutions for Euler and Navier-Stokes flows, is well suited for next generation flow analyses.In this study, the space-time CESE method was applied to solve scarfed nozzles flow-fields. Nozzle scarfing is frequently used for vectoring control of a space propulsion sub-system; it reduces nozzle weight and length and lowers nozzle thrust. A novel technique to enhance scarfed nozzles' thrust is discussed and investigated. Results of 2D and 3D flow analyses are presented.

    High-density genomic data is often analyzed by combining information over windows of adjacent markers. Interpretation of data grouped in windows versus at individual locations may increase statistical power, simplify computation, reduce sampling noise, and reduce the total number of tests performed. However, use of adjacent marker information can result in over- or under-smoothing, undesirable window boundary specifications, or highly correlated test statistics. We introduce a method for defining windows based on statistically guided breakpoints in the data, as a foundation for the analysis of multiple adjacent data points. This method involves first fitting a cubic smoothing spline to the data and then identifying the inflection points of the fitted spline, which serve as the boundaries of adjacent windows. This technique does not require prior knowledge of linkage disequilibrium, and therefore can be applied to data collected from individual or pooled sequencing experiments. Moreover, in contrast to existing methods, an arbitrary choice of window size is not necessary, since these are determined empirically and allowed to vary along the genome. Simulations applying this method were performed to identify selection signatures from pooled sequencing FST data, for which allele frequencies were estimated from a pool of individuals. The relative ratio of true to false positives was twice that generated by existing techniques. A comparison of the approach to a previous study that involved pooled sequencing FST data from maize suggested that outlying windows were more clearly separated from their neighbors than when using a standard sliding window approach. We have developed a novel technique to identify window boundaries for subsequent analysis protocols. When applied to selection studies based on F ST data, this method provides a high discovery rate and minimizes false positives. The method is implemented in the R package GenWin, which is publicly available from CRAN.

    Purpose: Currently, the chromosome translocation study is the best method to estimate the dose of an old radiation exposure. Fluorescent In Situ Hybridization (F.I.S.H.) technique allows an easy detection of this kind of aberrations. However, as only a few number of chromosomes is usually painted, some bias could skew the result. To evaluate the advantage of using full genome staining (M-F.I.S.H. technique) compared with three chromosomes labelling (F.I.S.H.-3 painting), we compared translocation yields in radiotherapy treated patients. Methods: Chromosome aberration analyses were performed on peripheral blood lymphocyte cultures of two patients treated for a throat cancer by radiotherapy. Blood samples were obtained, before, along the treatment and six or four months later. For each sample, a dicentrics analysis was performed together with translocation analysis either with F.I.S.H.-3 painting or M-F.I.S.H.. Results: By confronting results from the F.I.S.H.-3 painting technique and the M-F.I.S.H. technique, significant differences were revealed. The translocations yield seemed to be stable with the F.I.S.H.-3 painting technique whereas it is not the case with the M-F.I.S.H. technique. This difference in results was explained by the bias induced by F.I.S.H.-3 Painting technique in the visualisation of complex aberrations. Furthermore, we found the presence of a clone bearing a translocation involving a painted chromosome. Conclusions: According to the potential bias of F.I.S.H.-3 painting on translocations study, the M-F.I.S.H. technique should provide more precise and reproducible results. Because of its more difficult implement, it seems hardly applicable to retrospective dosimetry instead of F.I.S.H.-3 painting technique. (authors)

    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

    An important and not well-understood problem in the Reversed Field Pinch configuration is the anomalous ion heating. In all Ohmically heated RFPs, the ion temperature has been experimentally observed to be higher than can be accounted for by equilibration of energy from an Ohmically heated electron population. The mechanism driving the ions to such high energies is still debated. Different possible explanations have been investigated: kinetic Alfven waves turbulence, MHD relaxation processes and the excitation of an ion electrostatic wave by supra-thermal electrons. The measurement of the ion temperature is important in order to evaluate confinement. Furthermore, measurements can provide information on the mechanism behind the anomalous ion heating. The ion temperature is calculated from the neutral particles energy spectrum obtained by a neutral particles energy analyser based on the time of flight specifically developed for EXTRAP - T2R and here described in detail.

  20. The strut-and-tie models in reinforced concrete structures analysed by a numerical technique

    Directory of Open Access Journals (Sweden)

    V. S. Almeida

    Full Text Available The strut-and-tie models are appropriate to design and to detail certain types of structural elements in reinforced concrete and in regions of stress concentrations, called "D" regions. This is a good model representation of the structural behavior and mechanism. The numerical techniques presented herein are used to identify stress regions which represent the strut-and-tie elements and to quantify their respective efforts. Elastic linear plane problems are analyzed using strut-and-tie models by coupling the classical evolutionary structural optimization, ESO, and a new variant called SESO - Smoothing ESO, for finite element formulation. The SESO method is based on the procedure of gradual reduction of stiffness contribution of the inefficient elements at lower stress until it no longer has any influence. Optimal topologies of strut-and-tie models are presented in several instances with good settings comparing with other pioneer works allowing the design of reinforcement for structural elements.

  1. Who is responsible for the team’s results? Media framing of sports actors’ responsibility in major sports competitions

    Full Text Available Media are no longer just a witness to sports events, facilitating our access to them, but have become the most powerful judging platform for sports competitions, serving as a guide for their interpretation and evaluation. The present study focuses on media framing of sports actors’ responsibility when it comes to major sports competitions. Who is responsible for the team’s performance and results? In analysing media discourse, framing effects of sports events coverage will be examined from two inter-correlated dimensions, textually and visually. Based on an event-related corpus of on-line press articles from four national newspapers, this case study covers two major sports events: 2010 European Women’s Handball Championship and 2011 World Women’s Handball Championship. The discursive analysis of the press articles shows that, if winning competitive settings favour the emergence of a personification effect, building up sports heroes on both textual and visual dimensions, the responsibility of failure is rather diffused towards a collective referent. However, the visual component of press articles, along with the indirect strategy of addressing the responsibility issue throughout reported speech techniques, works as an alternative to the personification effect.

    Position data of players and athletes are widely used in sports performance analysis for measuring the amounts of physical activities as well as for tactical assessments in game sports. However, positioning sensing systems are applied in sports as tools to gain objective information of sports behavior rather than as components of intelligent spaces (IS). The paper outlines the idea of IS for the sports context with special focus to game sports and how intelligent sports feedback systems can benefit from IS. Henceforth, the most common location sensing techniques used in sports and their practical application are reviewed, as location is among the most important enabling techniques for IS. Furthermore, the article exemplifies the idea of IS in sports on two applications.

    Surface Plasmon Resonance (SPR) based on Mach-Zehnder interferometer (MZI) is a very accurate tool for the detection and analysis of molecular interactions. The performance of the proposed SPR phase sensor is dependent upon multiple performance parameters that include sensitivity, repeatability, drift and the induction speed of fluid into the flow cell. The SPR Mach-Zehnder interferometer is tested for different glycerin-water concentrations to check its performance based on the different parameters. This paper highlights the enhancement of the performance of SPR phase technique based on MZI that is influenced by different parameters, measured using glycerin solutions. These four performance parameters can affect the performance of SPR based on MZI and have a particular impact on the sensor output. It also provides us information about suitable working conditions for the SPR Mach-Zehnder interferometer sensor. The experiment data shows that the sensor's sensitivity is high for small concentrations of glycerin-water mixtures. Also, any change in drift as well as in induction speed of fluid can affect the performance of SPR Mach-Zehnder interferometer. The sensitivity of SPR phase sensor is high as it can measure glycerin concentration as low as 0.05%.

    It is only since the late 20th century that Sport and Exercise Medicine has emerged as a distinct entity in health care. In Israel, sports medicine is regulated by a State Law and a sport physician is certified after graduating a structured program. In the past, sports medicine was related to the diagnosis and treatment of injuries encountered by top athletes. In recent years, the scope of sport medicine has broadened to reflect the awareness of modern society of the dangers of physical inactivity. In this perspective the American College of Sport Medicine (ACSM) recently launched a program--"Exercise is Medicine", to promote physical activity in order to improve health and well-being and prevention of diseases through physical activity prescriptions. This program is from doctors and healthcare providers, adjusted to the patient or trainee. The sport physician does not replace a medical specialist, but having a thorough understanding about the etiology of a sport-related injury enables him to better focus on treatment and prevention. Therefore, Team Physicians in Elite Sport often play a role regarding not only the medical care of athletes, but also in the physiological monitoring of the athlete and correcting aberrations, to achieve peak physical performance. The broad spectrum of issues in sport and exercise medicine cannot be completely covered in one issue of the Journal. Therefore, the few reports that are presented to enhance interest and understanding in the broad spectrum of issues in sports and exercise medicine are only the tip of the iceberg.

    Full Text Available Travel time forecasting is an interesting topic for many ITS services. Increased availability of data collection sensors increases the availability of the predictor variables but also highlights the high processing issues related to this big data availability. In this paper we aimed to analyse the potential of big data and supervised machine learning techniques in effectively forecasting travel times. For this purpose we used fused data from three data sources (Global Positioning System vehicles tracks, road network infrastructure data and meteorological data and four machine learning techniques (k-nearest neighbours, support vector machines, boosting trees and random forest. To evaluate the forecasting results we compared them in-between different road classes in the context of absolute values, measured in minutes, and the mean squared percentage error. For the road classes with the high average speed and long road segments, machine learning techniques forecasted travel times with small relative error, while for the road classes with the small average speeds and segment lengths this was a more demanding task. All three data sources were proven itself to have a high impact on the travel time forecast accuracy and the best results (taking into account all road classes were achieved for the k-nearest neighbours and random forest techniques.

The relation has transformed in a stable relation, the two forces – the sponsor and the sponsored – transforming into two companions of journey. The effort undertaken in this work was focused on analyzing the modern aspects of the partnership generated through sports sponsorship.The current issue and sport sponsorship has come a long way since the first action of its kind until now. Based on the presentation of new concepts on the development efforts in sport sponsorship, content provides a detailed analysis of the actual specifics of this type of activity. Analysis of influence vectors sponsorship process gives us a picture of the forces that can act on this. At the end of our research we focused attention on elements that empowers sports portfolio in terms of corporate interest, the potentiation commercial message and image association. This technique of promotional community for and through sports is maybe the one that manifests the most “laic” status among the promotional forms. This epithet implies a metaphorical approach given by the possibility of accomplishing some objectives that can have some more obvious “corporality” than in the case of the other forms of promotion used in the sports industry. Sports sponsorship has been an early ally of sports, and has remained a basic communicational technique. This fact is due to some determination in double sense: on the one hand, sport has adapted permanently to the dynamics of the range of sponsorship techniques and, on the other hand, the sponsorship tried to use the chameleon-like offer of the sports potential.

    Full Text Available Participation in sports activities combined with unique sports resources can provide people with extraordinary experiences. It is especially true for tourism where sports activities are an important content of stay. The aim of this paper is to analyse how sports experiences could be planned and managed for the tourism purposes from the aspect of sports facility managers. In addition, the interrelations within the four realms of an experience were analysed and supported by proposed management models and examples. Results of the analysis indicate that it is possible for a facility to provide a full spectrum of experiences but only if it meets the standards of professional sports. Recommendations suggested by the paper provide new insight on organising the sports offer in the destination, and can be used by sports facility managers in order to better serve sports and sports tourism needs

    Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

  15. Application of infrared thermography in sports science

    CERN Document Server

    2017-01-01

    This book addresses the application of infrared thermography in sports, examining the main benefits of this non-invasive, non-radiating and low-cost technique. Aspects covered include the detection of injuries in sports medicine, the assessment of sports performance due to the existing link between physical fitness and thermoregulation and the analysis of heat transfer for sports garments and sports equipment. Although infrared thermography is broadly considered to be a fast and easy-to-use tool, the ability to deliver accurate and repeatable measurements is an important consideration. Furthermore, it is important to be familiar with the latest sports studies published on this technique to understand its potential and limitations. Accordingly, this book establishes a vital link between laboratory tests and the sports field. .

    1975-08-01

    The bioenergetics of Simulium spp. and Cheumatopsyche analis from Rattlesnake Springs and Snively Creek, respectively, Benton County, Washington and Tricorthodes minutus from Deep Creek, Oneida County, Idaho were studied using a variety of techniques. Ingestion rates were measured using food sources (diatoms, finely ground watercress, bacteria, and blue-green algae) labelled with /sup 51/Cr and /sup 14/C. Theoretical ingestion rates were calculated from analyses of gut weights and digestion times. Assimilation efficiencies (AE) were determined using the /sup 14/C and dual-label (/sup 51/Cr, /sup 14/C) methods and the ash-ratio technique. The dual-label method provided reliable results when leaching of isotopes from food and feces were not significant. Provided the /sup 51/Cr activity density of food is sufficient, the time required for digestion can also be more accurately determined with /sup 51/Cr than with /sup 14/C. The ash-ratio method provided a wide range of AE values and is not as reliable as the dual-label method because mineral assimilationis unpredictable. Assimilation rates were derived for these animals using the ingestion rate and AE, by several methods employing /sup 14/C uptake curves, and by differences in /sup 51/Cr- and /sup 14/C-derived accumulation values. Methods used to measure other energy budget components are also given. A system was developed for combusting biological samples containing /sup 14/C and determining cpm /sup 14/C and total carbon from a single sample. This method employs Van Slyke wet oxidation, forced circulation and scrubbing of the gases of combustion, and collection of CO/sub 2/ in ethanolamine. Radioactivity in this system was determined by scintillation counting and total carbon by a gravimetric precipitation method. (auth)

    From the view of sports industry, dance sport market can be divided into following types: market for dance sport competition; market for dance sport entertainment; market for dance sport goods; marker for training professionals; and market for dance sport media. From the analyses and discussions we can concluded: 1.Chinese dance sport experienced single event period, multiple development period and reformation period. Nowadays,top quality events have becoming more and more mature and the effectiveness of Dance Sport marketization development has been highlighted. 2.The motive force of the development of market mode for the sports dance competition are deeply innovation and the construction of the primitive flat, the support by the rapid and benign socioeconomic environment,the foundation for the future development given by the improvement of life condition and the change of consumption patterns from survival form to enjoying and developing form, the huge consumer market of sports dance, the culture quality of the sports dance and the broad influence in the world. 3.Under the management of CDSF, there are three types of typical events: Chinese sport dance title matches, club league matches, and international open matches or tournaments. 4.The general adoption of market principle for Sports Dance competition is the club mode and proefssionalization. Therefore, it is necessary for us to found the professional united companies certified by practice. 5.Operations for the market mode of other athletic competitions can provide experience for the construction of market structural mode of dance sport competitions. We should study these successful experience and improve the education for the reserve forces of sports dance persistently. And then construct a more reasonable, more normative competition mechanism to promote the development of sports dance in a healthy and mature way.

    Due to the high importance of the material vestiges for a culture of a nation, the Brazilian Council for Environment determined that the license to establish new enterprises are subjected to a technical report concerning environmental impact, including archaeological sites affected by that enterprise. Therefore, answering the report related to the Program for Prospection and Rescue of the Archaeological Patrimony of the Areas impacted by the installation of the Second Line of Samarco Mining Pipeline, the archaeological interventions were carried out along the coast of Espirito Santo. Tupi-Guarani Tradition vestiges were found there, where the main evidence was a interesting ceramics. Archaeology can fill the gap between ancient population and modern society elucidating the evidences found in archaeological sites. In this context, several ceramic fragments found in the archaeological sites - Hiuton and Bota-Fora - were analyzed by neutron activation technique, {sub k}0-standardization method, at CDTN using the TRIGA MARK I IPR-R1 reactor, in order to characterize their elemental composition. The elements As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Ga, Hf, K, La, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb, Zn and Zr were determined. Applying R software, a robust multivariate statistical analysis, the results pointed out that the pottery from the sites was made with clay from different sources. The X-ray powder diffraction analyses were carried out to determine the mineral composition and Moessbauer spectroscopy was applied to provide information on both the degree of burning and atmosphere in order to reconstruct the Indian burning strategies temperature used on pottery production.

    Six middle-aged lactovegetarians (three men and three women) collected copies of four 24-h diets using the duplicate portion sampling technique. By chemical analyses, the nutrient composition of the lactovegetarian diet was determined in detail and compared with that of a mixed Swedish diet (normal) and a vegan diet (vegan) studied previously. The nutrient composition of the lactovegetarian diet expressed per 1000 kcal represented an average between normal and vegan diets. It was in closer agreement with Swedish recommended dietary allowances than the normal Swedish diet. Thus, the lactovegetarian diet contained 35% of the energy as fat and was rich in polyunsaturated fatty acids, especially linoleic acid, which resulted in a polyunsaturated/saturated fat ratio of 0.6. The lactovegetarian diet had a cholesterol concentration only half of that of a normal diet. Protein content and amino acid composition were well above recommendations. The lactovegetarian diets contained less sucrose than normal and vegan diets, but the sum of the intake of low molecular weight carbohydrates was comparable to normal and vegan diets. Dietary fiber was three times higher than in a normal diet. Essential minerals and trace elements, ie, Ca, Mg, Na, K, Fe, Zn, Cu, Se, satisfied current requirements. The intake of vitamin B12 by the lactovegetarians was around 1.4 micrograms daily, which is below the recommendations. The intake of folates was high, 300 to 400 micrograms daily. The clinical and biochemical investigation of the subjects revealed no signs of nutritional deficiency. Their plasma lipoproteins and the blood pressures were low for their age, in agreement with observations made earlier in a group of vegans.

    Linking model and data, we detail the LANL diving reduced gradient bubble model (RGBM), dynamical principles, and correlation with data in the LANL Data Bank. Table, profile, and meter risks are obtained from likelihood analysis and quoted for air, nitrox, helitrox no-decompression time limits, repetitive dive tables, and selected mixed gas and repetitive profiles. Application analyses include the EXPLORER decompression meter algorithm, NAUI tables, University of Wisconsin Seafood Diver tables, comparative NAUI, PADI, Oceanic NDLs and repetitive dives, comparative nitrogen and helium mixed gas risks, USS Perry deep rebreather (RB) exploration dive,world record open circuit (OC) dive, and Woodville Karst Plain Project (WKPP) extreme cave exploration profiles. The algorithm has seen extensive and utilitarian application in mixed gas diving, both in recreational and technical sectors, and forms the bases forreleased tables and decompression meters used by scientific, commercial, and research divers. The LANL Data Bank is described, and the methods used to deduce risk are detailed. Risk functions for dissolved gas and bubbles are summarized. Parameters that can be used to estimate profile risk are tallied. To fit data, a modified Levenberg-Marquardt routine is employed with L2 error norm. Appendices sketch the numerical methods, and list reports from field testing for (real) mixed gas diving. A Monte Carlo-like sampling scheme for fast numerical analysis of the data is also detailed, as a coupled variance reduction technique and additional check on the canonical approach to estimating diving risk. The method suggests alternatives to the canonical approach. This work represents a first time correlation effort linking a dynamical bubble model with deep stop data. Supercomputing resources are requisite to connect model and data in application.

    In order to investigate the behaviour of athletes in choosing sports, we analyse data from part of the We-Sport database, a vertical social network that links athletes through sports. In particular, we explore connections between people sharing common sports and the role of age and gender by applying "network science" approaches and methods. The results show a disassortative tendency of athletes in choosing sports, a negative correlation between age and number of chosen sports and a positive correlation between age of connected athletes. Some interesting patterns of connection between age classes are depicted. In addition, we propose a method to classify sports, based on the analyses of the behaviour of people practising them. Thanks to this brand new classifications, we highlight the links of class of sports and their unexpected features. We emphasise some gender dependency affinity in choosing sport classes.

    Full Text Available The article is devoted to the study of cultural and mental specificity of language units in the sport communication. The study was conducted on the material of English, Russian and German analytical articles, thematically related to tennis. Using the technique of cross-language comparison it is revealed significant characteristic parameters of sports discourse. The proposed comparative procedure consists in three stages of analysis: linguistic, cognitive-communicative and linguistic-cultural. During the analysis at each step there were identified certain criteria specific to the sport discourse in three linguasocieties. Sport communication reflects not only the specificity and originality of the language, but also the traditions, history, mentality, culture, and behavior patterns of modern professional sport community. Comparative study of sport discourse reveals the cultural, linguistic and cognitive features of sublanguage sports and allows to get a common view of the structure of sport analytical articles.

    Participation in fantasy sports increases annually. Wagering on fantasy sports is a form of gambling and researchers have found that fantasy sports participants are more likely to engage in other forms of sports betting than non-fantasy players; however, no published studies have examined whether there is a relationship between fantasy sports participation and gambling-related problems. Our study examined whether fantasy sports participation is associated with gambling-related problems among college students. We assessed fantasy sports participation and endorsement of DSM-5 gambling disorder (GD) criteria among a large convenience sample (N=1556) of college students via an online health survey. We found that 11.5% of respondents participated in fantasy sports in the past year, the majority of which were males. Logistic regression analyses indicated that males who play fantasy sports for money and females who play fantasy sports (for money or not) were more likely to experience gambling-related problems.

    Use pattern-centered methods to examine how adolescents' alcohol use and sports activities are related both to childhood sport and problem behavior and to heavy drinking in early adulthood. The data used in this study come from four waves of the Michigan Study of Adolescent Life Transitions (MSALT) that began in 1983, when participants were approximately age 12, and continued into early adulthood, when participants were approximately age 28. Sixty per cent of the approximately 1000 MSALT youth living in south-eastern Michigan were females and 97% were European American. Approximately 28% of one or both parents held at least a college degree, and 45% held a high school diploma or lower. Pattern-centered analyses revealed that the relation between adolescent sport activity and age 28 heavy alcohol use obtained primarily for sport participants who were also using more than the average amount of alcohol and other drugs at age 18. Similarly, children who were characterized by relatively high levels of sport participation, aggression and other problem behavior at age 12 were more likely than expected by chance to become sport participants who used more than the average amount of alcohol and other drugs at age 18. The results indicate that childhood problem behavior and adolescent sport participation can, but do not necessarily, presage heavy drinking in adulthood and that pattern-centered analytical techniques are useful for revealing such theoretically generated predictions.

    A strict vegetarian diet [vegan diet (VD)] was investigated. Six middle-aged vegans (three men and three women) collected copies of 24-h diets using the duplicate portion sampling technique. By chemical analyses, the nutrient composition was determined in detail and compared with corresponding figures of a normal mixed Swedish diet. In the VD 30% of the energy originated from fat compared with 40% in normal Swedish mixed diet (MD). Linoleic acid was the dominant fatty acid (60% of total fat in VD versus 8% in MD). The VD contained 24 g protein/1000 kcal compared to 30 g/1000 kcal in MD, but the intake of essential amino acids by the vegans exceeded the recommendations. Dietary fiber was about 5 times higher in the vegan diet (29 versus 6 g/1000 kcal) and sucrose similar to MD (18 versus 21 g/1000 kcal). Among the inorganic nutrients the concentration of calcium (351 versus 391 mg/1000 kcal) and sodium (53 versus 49 mmol/1000 kcal) were similar in both types of diets but the amount of potassium (56 versus 30 mmol/1000 kcal, magnesium (300 versus 110 mg/1000 kcal), iron (9 versus 6.5 mg/1000 kcal), zinc (6.5 versus 4.7 mg/1000 kcal), and copper (2 versus 0.7 mg/1000 kcal) were nearly doubled. Iodine (39 versus 156 micrograms/1000 kcal and selenium (5 versus 17 micrograms/1000 kcal) were much lower in the VD, selenium even being undetectable in several 24-h diets. The VD was rich in folic acid (301 versus 90 micrograms/1000 kcal in MD) but the intake of vitamin B12 was only 0.3 to 0.4 microgram/day (MD: 3 to 4 micrograms/day). No clinical signs of nutritional deficiency were observed in the vegans. Serum protein levels of the vegans as well as their serum lipoproteins were near the lower range of the reference group. In addition, none of the vegans was overweight and their blood pressures were low for their age.

    Tennis may be considered a static and dynamic form of exercise with many well-demonstrated health benefits. Tennis has similar rates of injury to other individual recreational sports and junior competitive sports, without the catastrophic risk of contact/collision sports. Classifying tennis players into junior and elite categories versus adult recreational players may help in outlining volume of play recommendations, exposure risk, and types of injuries. Junior and elite players tend to tolerate higher volumes, have more acute and lower extremity injuries, and have more serious overuse stress injuries. Adult recreational players tend to tolerate lower volumes, have more overuse and upper extremity injuries, and more conditions that are degenerative. Many tennis players also develop asymmetric musculoskeletal adaptations, which may increase risk of specific injury. Tennis-specific evaluations may identify these at-risk segments, help guide preventive strategies including technical errors, and assist in developing return-to-play recommendations. Other racket sports such as squash, badminton, and racquetball have less data available but report both acute and traumatic injuries less commonly seen in tennis.

    Femoral shaft fractures can be treated using retrograde interlocking nailing systems; however, fracture nonunion still occurs. Dynamic fixation techniques, which remove either the proximal or distal locking screws, have been used to solve the problem of nonunion. In addition, a surgical rule for dynamic fixation techniques has been defined based on past clinical reports. However, the biomechanical performance of the retrograde interlocking nailing systems with either the traditional static fixation technique or the dynamic fixation techniques has not been investigated by using nonlinear numerical modeling. Three-dimensional nonlinear finite element models were developed, and the implant strength, fixation stability, and contact area of the fracture surfaces were evaluated. Three types of femoral shaft fractures (a proximal femoral shaft fracture, a middle femoral shaft fracture, and a distal femoral shaft fracture) fixed by three fixation techniques (insertion of all the locking screws, removal of the proximal locking screws, or removal of the distal locking screws) were analyzed. The results showed that the static fixation technique resulted in sufficient fixation stability and that the dynamic fixation techniques decreased the failure risk of the implant and produced a larger contact area of the fracture surfaces. The outcomes of the current study could assist orthopedic surgeons in comprehending the biomechanical performances of both static and dynamic fixation techniques. In addition, the surgeons could also select a fixation technique based on the specific patient situation using the numerical outcomes of this study.

  20. Proximity to sports facilities and sports participation for adolescents in Germany.

    Full Text Available To assess the relationship between proximity to specific sports facilities and participation in the corresponding sports activities for adolescents in Germany.A sample of 1,768 adolescents aged 11-17 years old and living in 161 German communities was examined. Distances to the nearest sports facilities were calculated as an indicator of proximity to sports facilities using Geographic Information Systems (GIS. Participation in specific leisure-time sports activities in sports clubs was assessed using a self-report questionnaire and individual-level socio-demographic variables were derived from a parent questionnaire. Community-level socio-demographics as covariates were selected from the INKAR database, in particular from indicators and maps on land development. Logistic regression analyses were conducted to examine associations between proximity to the nearest sports facilities and participation in the corresponding sports activities.The logistic regression analyses showed that girls residing longer distances from the nearest gym were less likely to engage in indoor sports activities; a significant interaction between distances to gyms and level of urbanization was identified. Decomposition of the interaction term showed that for adolescent girls living in rural areas participation in indoor sports activities was positively associated with gym proximity. Proximity to tennis courts and indoor pools was not associated with participation in tennis or water sports, respectively.Improved proximity to gyms is likely to be more important for female adolescents living in rural areas.

    Extremely low weight and rapid changes in weight and body composition have become major concerns in many sports, but sufficiently accurate field methods for body composition assessment in athletes are missing. This study aimed to explore the use of ultrasound methods for assessment of body fat content in athletes. 19 female athletes (stature: 1.67(± 0.06) m, weight: 59.6(± 7.6) kg; age: 19.5(± 3.3) years) were investigated by three observers using a novel ultrasound method for thickness measurement of uncompressed subcutaneous adipose tissue and of embedded structures. Two observers also measured skinfold thickness at eight International Society for the Advancement of Kinanthrometry (ISAK) sites; mean skinfold values were compared to mean subcutaneous adipose tissue thicknesses measured by ultrasound. Interobserver reliability of imaging and evaluation obtained by this ultrasound technique: intraclass correlation coefficient ICC=0.968 (95% CI 0.957 to 0.977); evaluation of given images: ICC=0.997 (0.993 to 0.999). Skinfold compared to ultrasound thickness showed that compressibility of subcutaneous adipose tissue depends largely on the site and the person: regression slopes ranged from 0.61 (biceps) to 1.59 (thigh) and CIs were large. Limits of agreement ranged from 2.6 to 8.6 mm. Regression lines did not intercept the skinfold axis at zero because of the skin thickness being included in the skinfold. The four ISAK trunk sites caused ultrasound imaging problems in 13 of 152 sites (8 ISAK sites, 19 athletes). The ultrasound method allows measurement of uncompressed subcutaneous adipose tissue thickness with an accuracy of 0.1-0.5 mm, depending on the probe frequency. Compressibility of the skinfold depends on the anatomical site, and skin thickness varies by a factor of two. This inevitably limits the skinfold methods for body fat estimation. Ultrasound accuracy for subcutaneous adipose tissue measurement is limited by the plasticity of fat and furrowed tissue

    For several years, new analysis and observation techniques have been developed, which have considerably improved material research. Almost all these techniques are based on the interaction of a beam of `primary particles` (electrons, photons, ions, particles, etc) with target. Correct and appropriate use of these techniques requires a good knowledge of these interactions and their consequences (emissions of `secondary particles`, modifications of the primary beam and target, etc). The first part of this report deals with the radiation/material interactions according to the nature of the radiation and its energy. The nature and consequences of the interaction of an electromagnetic wave, a beam of electrons, ions and neutrons are examined over an extended range of energy from MeV to MeV. Certain notions such as the analysis area, spatial resolutions or limits of detection can also be defined. In the second part, some of the most important and widespread techniques of analysis and observation are compared in terms of properties and performance. In particular, there is a brief principle of the technique, nature of the data obtained, spatial resolution, and the limits of detection with today`s methods permit.

    Organized sport provides one option for children to be physically active. However, there is a paucity of information about the relationship between children's participation in organized sport and their diet, and specifically their sports drink consumption. Therefore, the relationship between sports participation in children and the consumption of sports drinks, sugar-sweetened beverages (SSBs) and other components of diet was examined. A cross-sectional descriptive study was conducted using baseline data from the Action Schools! BC Dissemination study cohort (n = 1421; 9.90 (0.58) y; 736 girls, 685 boys). The differences between the dietary behaviours of children participating in organized sport (sport) versus those that did not participate (non-sport) was examined. A modified Physical Activity Questionnaire for Older Children (PAQ-C) was used to measure physical activity levels and participation in organized sport. A Food Frequency Questionnaire (FFQ) and 24-hour dietary recall were used to assess eating behaviour and macronutrient intake (including protein, fat, and carbohydrate as well as sugar, fibre and total calories). Fruit, vegetable and beverage quantities were hand-tallied from the dietary recall. Fruit, vegetable and beverage frequency was assessed using the FFQ. Analysis of covariance (ANCOVA) was used to analyse differences between groups and a chi-square test of association was use to determine if participation in sport was significantly associated with the proportion of children consuming sports drinks and SSBs, and with gender. Children involved in sport had a lower body mass index (BMI) and were more physically active than children in the non-sport group (p sports drinks and no difference in consumption of sports drink between sport and non-sport participants (p > .05) was observed. However, children involved in organized sport consumed more total calories, fat, fibre, fruit, vegetables and non-flavoured milk (p sport children. Children

    Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome characterized by an excessive prenatal and postnatal growth, macrosomia, macroglossia, and hemihyperplasia. The molecular basis of this syndrome is complex and heterogeneous, involving genes located at 11p15.5. BWS is correlated with assisted reproductive techniques. BWS in individuals born following assisted reproductive techniques has been found to occur four to nine times higher compared to children with to BWS born after spontaneous conception. Here, we report a series of 187 patients with to BWS born either after assisted reproductive techniques or conceived naturally. Eighty-eight percent of BWS patients born via assisted reproductive techniques had hypomethylation of KCNQ1OT1:TSS-DMR in comparison with 49% for patients with BWS conceived naturally. None of the patients with BWS born via assisted reproductive techniques had hypermethylation of H19/IGF2:IG-DMR, neither CDKN1 C mutations nor patUPD11. We did not find differences in the frequency of multi-locus imprinting disturbances between groups. Patients with BWS born via assisted reproductive techniques had an increased frequency of advanced bone age, congenital heart disease, and decreased frequency of earlobe anomalies but these differences may be explained by the different molecular background compared to those with BWS and spontaneous fertilization. We conclude there is a correlation of the molecular etiology of BWS with the type of conception. © 2016 Wiley Periodicals, Inc.

    A surgical approach with plaque incision and graft (PIG) to correct Peyronie's disease is the best method for complex, large deviations. However, the geometric and mechanical consequences of this intervention are poorly understood. The aim of this study was to analyze the geometric and mechanical consequences of PIG on penile straighten surgery. A tridimensional penile simile model with a curvature of 85° was created to test all of the most common PIG techniques. PIG with double-Y, H-shape, and Egydio techniques were used to rectify the curved penile model. The results that differed from a rectified cylinder shape were highlighted. All of the analyzed techniques created a geometric distortion that could be linked to poor surgical results. We suggest a new technique to resolve these abnormalities. Current techniques designed to correct penile deviation using PIG present geometric and mechanical imperfections with potential consequences to the postoperative success rate. The new technique proposed in this report could be a possible solution to solve the geometric distortion caused by PIG. © 2014 International Society for Sexual Medicine.

    Procedures for identifying patterns in scatterplots generated in Monte Carlo sensitivity analyses are described and illustrated. These procedures attempt to detect increasingly complex patterns in scatterplots and involve the identification of (i) linear relationships with correlation coefficients, (ii) monotonic relationships with rank correlation coefficients, (iii) trends in central tendency as defined by means, medians and the Kruskal-Wallis statistic, (iv) trends in variability as defined by variances and interquartile ranges, and (v) deviations from randomness as defined by the chi-square statistic. A sequence of example analyses with a large model for two-phase fluid flow illustrates how the individual procedures can differ in the variables that they identify as having effects on particular model outcomes. The example analyses indicate that the use of a sequence of procedures is a good analysis strategy and provides some assurance that an important effect is not overlooked.

    DIANA-LUIZA DUMITRIU

    2014-12-01

    Full Text Available This paper analyses the social field of sports within the general frame of social dramaturgy, by using three metaphors that are grounded on Goffman’s conceptual field: sport as play, sport as game and sport as ritual. After discussing “what”, “how” and “to what extent” can Goffman’s concepts be re-contextualized in understanding the dynamics of the sport acts, I went further and integrated the three metaphors into a more comprehensive analytic model. The multidimensional model of sport dramaturgy that I have built around Goffman’s hard-core concepts covers: the dramaturgical dimension, the strategic dimension and the ritual dimension of sport acting as complementary elements that can provide an integrative perspective upon the sport dynamics. Every dimension of this interactional model implies a specific definition for the competitive situation, for the sport actor and for his dispositional orientation when faced with a competitive situation

    2016-06-01

    Full Text Available The text presents and analyses manifestations of modernity and postmodernity in the field of competitive and recreational sport, physical education, leisure, and tourism. The paper builds upon an extensive literature survey and presents the concept and key features of postmodern societies and the modernity-postmodernity debate in sports with reference to postmodern tendencies in tourism. We have attempted to determine the proportions of tradition, modernity, and postmodernity in contemporary sport and tourism, keeping in mind that, similarly to contemporary societies as a whole, sport is undoubtedly a mixture of traditional, modern, and Fordist elements with postmodern and post-Fordist features. We present and discuss the prevailing belief that the key elements of leisure sport are mostly postmodern and focused on the notion of individualisation and freedom expressed especially in alternative sports, while commercialised mainstream sport follows the regular mass-media show-business development path, maintaining a significant amount of modern concepts, such as the importance of national identities. Special attention is also paid to the Olympic Games as a specific and very efficient mixture of modernity and postmodernity. More so than at any point in the past, and despite the actual proportions of modernity and postmodernity that it contains, contemporary sport has become an integral part of postmodern societies and their lifestyle, with technology-determined individualisation of sport consumption and leisure sport participation.

    The number of systematic reviews published in the orthopaedic literature has increased, and these reviews can help guide clinical decision making. However, the quality of these reviews can affect the reader's ability to use the data to arrive at accurate conclusions and make clinical decisions. To evaluate the methodological and reporting quality of systematic reviews and meta-analyses in the sports medicine literature to determine whether such reviews should be used to guide treatment decisions. The hypothesis was that many systematic reviews in the orthopaedic sports medicine literature may not follow the appropriate reporting guidelines or methodological criteria recommended for systematic reviews. Systematic review. All clinical sports medicine systematic reviews and meta-analyses from 2009 to 2013 published in The American Journal of Sports Medicine (AJSM), The Journal of Bone and Joint Surgery (JBJS), Arthroscopy, Sports Health, and Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) were reviewed and evaluated for level of evidence according to the guidelines from the Oxford Centre for Evidence-Based Medicine, for reporting quality according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, and for methodological quality according to the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Analysis was performed by year and journal of publication, and the levels of evidence included in the systematic reviews were also analyzed. A total of 200 systematic reviews and meta-analyses were identified over the study period. Of these, 53% included evidence levels 4 and 5 in their analyses, with just 32% including evidence levels 1 and 2 only. There were significant differences in the proportion of articles with high levels of evidence (P Sports Health and KSSTA on the PRISMA and AMSTAR.

    Hurling in Cornwall, la soule in Britanny, Shrovetide football in England: Popular games have normally been treated as forerunners of modern sport, sport having regulated the space and the time of the game, the (non-) violence of behaviour, the control of results, the planning, strategy, tactics......, techniques and evaluation of the competitive action. This is told as a story of social improvement and progress--and about turning unhealthy wildness into civilized 'healthy' sport activity. What sociological analysis of game-playing tended to ignore was the laughter of the participants. With the seriousness...... of modern sport, as it was established in the nineteenth century, a culture of laughter disappeared.

    Extracurricular school-based sports are considered to be an ideal means of reaching children who are not active in community sports. The purposes of this study were to examine the extent to which pupils not engaging in community sports do participate in extracurricular school-based sports, and to assess whether extracurricular school-based sports participants are more physically active and/or more autonomously motivated towards sports in daily life than children who do not participate in extracurricular school-based sports. One thousand forty-nine children (53.7% boys; M age = 11.02 years, SD = 0.02) out of 60 classes from 30 Flemish elementary schools, with an extracurricular school-based sports offer, completed validated questionnaires to assess physical activity (Flemish Physical Activity Questionnaire) and motivation (Behavioral Regulations in Physical Education Questionnaire). Multilevel regression analyses were conducted to examine the data generated from these questionnaires. More than three quarters of the children (76%) reported participating in extracurricular school-based sports during the current school year and 73% reported engaging in organized community sports. Almost two third of the children (65%) not participating in community sports stated that they did participate in extracurricular school-based sports. Extracurricular school-based sports participants were significantly more physically active than children not participating in extracurricular school-based sports (β = 157.62, p sports participation × community sports participation) were found for autonomous motivation, with boys engaging in extracurricular school-based sports but not in community sports being significantly more autonomously motivated towards sports than boys not engaging in community or extracurricular school-based sports (β = 0.58, p = 0.003). Such differences were not noted among girls. If extracurricular school-based sports are offered at school, the vast majority of

With this aim, we set out to determine the most frequent errors made by 44 students when performing this technique and how these mistakes relate. In order to do so, an observational analysis was carried out using the OSJUDO-UKG instrument and the data were registered using Match Vision Studio (Castellano, Perea, Alday and Hernández, 2008.

    In the present work, the data assimilation problem in meteorology and physical oceanography is re-examined using the variational optimal control approaches in combination with regularization techniques in inverse problem. Here the estimations of the initial condition,boundary condition and model parameters are performed simultaneously in the framework of variational data assimilation. To overcome the difficulty of ill-posedness, especially for the model parameters distributed in space and time, an additional term is added into the cost functional as a stabilized functional. Numerical experiments show that even with noisy observations the initial conditions and model parameters are recovered to an acceptable degree of accuracy.

    Sample data in the Earth and environmental sciences are limited in quantity and sampling location and therefore, sophisticated spatial modeling techniques are indispensable for accurate imaging of complicated structures and properties of geomaterials. This paper presents several effective methods that are grouped into two categories depending on the nature of regionalized data used. Type I data originate from plural populations and type II data satisfy the prerequisite of stationarity and have distinct spatial correlations. For the type I data, three methods are shown to be effective and demonstrated to produce plausible results: (1) a spline-based method, (2) a combination of a spline-based method with a stochastic simulation, and (3) a neural network method. Geostatistics proves to be a powerful tool for type II data. Three new approaches of geostatistics are presented with case studies: an application to directional data such as fracture, multi-scale modeling that incorporates a scaling law,and space-time joint analysis for multivariate data. Methods for improving the contribution of such spatial modeling to Earth and environmental sciences are also discussed and future important problems to be solved are summarized.

    Differentiation of bone marrow mesenchymal stem cells (BMSCs) into neural cells has received significant attention in recent years. However, there is still no practical method to evaluate differentiation process non-invasively and practically. The cellular quality evaluation method is still limited to conventional techniques, which are based on extracting genes or proteins from the cells. These techniques are invasive, costly, time consuming, and should be performed by relevant experts in equipped laboratories. Moreover, they cannot anticipate the future status of cells. Recently, cell morphology has been introduced as a feasible way of monitoring cell behavior because of its relationship with cell proliferation, functions and differentiation. In this study, rat BMSCs were induced to differentiate into neurons. Subsequently, phase contrast images of cells taken at certain intervals were subjected to a series of image processing steps and cell morphology features were calculated. In order to validate the viability of applying image-based approaches for estimating the quality of differentiation process, neural-specific markers were measured experimentally throughout the induction. The strong correlation between quantitative imaging metrics and experimental outcomes revealed the capability of the proposed approach as an auxiliary method of assessing cell behavior during differentiation.

The purpose of this study was to compare advertising and sales promotion strategies, the effects of different strategies in sport production companies to retain or to gain market share among selected firms, which were active in Iran. The method of survey was descriptive – analytical and some questionnaires were used for collecting data in Likert scale. The validity of the questionnaire were estimated by interview with professors and exports in marketing and sport marketing and the reliability was assessed by using Cronbach's alpha (α= 0.89. Statistical population of the study includes Sport Goods-Producing companies in Iran (N= 180 and 122 firms formed the study sample. For testing the hypothesis, we have used Paired Samples T-Test. The analysis of findings showed that there was a meaningful difference between using advertising and sales promotion strategies. In general, we can say, there are some limited applications of using techniques and methods of sales promotion strategies in Iranian sport industry and methods of advertising. Consequently, regarding the intense competition among companies as well as fast growth of markets and fast changes in consumer’s behavior, identifying the best methods for corresponding relationship to customer would be required.

    Endothelial dysfunction is considered to be a key factor in the development of atherosclerosis, and the measurement of flow-mediated vasodilation (FMD) in brachial and other conduit arteries has become a common method to assess the status of endothelial function in vivo. Based on the direct relationship between the FMD response and local shear stress on the conduit brachial artery endothelium, we hypothesize that measuring relevant changes in the brachial wall strain tensor would provide a non-invasive tool for assessing vascular mechanics during post-occlusion reactive hyperemia. Direct measurement of the wall strain tensor due to FMD has not yet been reported in the literature. In this work, a noninvasive direct ultrasound-based strain tensor measuring (STM) technique is presented to assess changes in the mechanical parameters of the vascular wall during post-occlusion reactive hyperemia and/or FMD, including local velocities and displacements, diameter change, local strain tensor and strain rates. The STM technique utilizes sequences of B-mode ultrasound images as its input with no extra hardware requirement, and its algorithm starts with segmenting a region of interest within the artery and providing the acquisition parameters. Then a block matching technique based on speckle tracking is employed to measure the frame-to-frame local velocities. Displacements, diameter change, local strain tensor and strain rates are then calculated by integrating or differentiating velocity components. The accuracy of the STM algorithm was assessed in vitro using phantom studies, where an average error of 7% was reported using different displacement ranging from 100 µm to 1000 µm. Furthermore, in vivo studies using human subjects were performed to test the STM algorithm during pre- and post-occlusion. Good correlations (|r| >0.5, P < 0.05) were found between the post-occlusion responses of diameter change and local wall strains. Results indicate the validity and versatility of

    Experimental division of soil organic matter (SOM) into functional pools has the potential to improve soil C modelling. Soil physical fractionation techniques seek to quantify these pools, however the fractions isolated vary in number, size, ecological role and composition. The use of different techniques to quantify soil C fractions in different studies presents a question - do similar fractions isolated by different methods fit the same conceptual definition? This study examined a sandy loam from the south-west of Scotland, sampled in summer, which had been under grassland management for at least 20 years. We compared average 14C ages of SOM fractions isolated using three published and frequently applied physical fractionation methods (1) a density separation technique isolating three fractions - free light (FLF) 1.8 g cm 3 (Sohi et al, 2001); (2) a combined physical and chemical separation isolating five fractions: sand and aggregates (S+A) > 63 µm and > 1.8 g cm-3, particulate organic matter (POM) > 63 µm and 45 µm, residual organic carbon (rSOC) the residue left after s+c is oxidised with NaOCl, and dissolved organic carbon (DOC) 4000 years BP for DOC and POM. Both Method 3 fractions were dominated by modern C. The average 14C ages of FLF, IALF, DOC and POM were surprisingly higher than the mineral bound fractions, although they made up a relatively small proportion of the total organic C (8.4 and 12.4 % for Methods 1 and 2 respectively). These results will be discussed alongside data from FTIR and UV-vis spectroscopy. The characterisation of physically separated organic matter pools is likely to provide improved opportunities for modelling the long term behaviour of SOM on the basis of defined chemical and physical properties.

  20. Enhancement in Sport, and Enhancement outside Sport.

    2007-12-01

    Sport is one of the first areas in which enhancement has become commonplace. It is also one of the first areas in which the use of enhancement technologies has been heavily regulated. Some have thus seen sport as a testing ground for arguments about whether to permit enhancement. However, I argue that there are fairness-based objections to enhancement in sport that do not apply as strongly in some other areas of human activity. Thus, I claim that there will often be a stronger case for permitting enhancement outside of sport than for permitting enhancement in sport. I end by considering some methodological implications of this conclusion.

  1. Sports Culture and Sports in Turkey

    Full Text Available Sports culture indicates all kinds of morals, products, and behavior. This study aims to argue sports as a cultural element and its appearence in Turkey. This is a descriptive study based on theoretical argument. It is periodic since it is limited to a given term and it is also relied upon literature review. People's adaptations to living conditions are related to culture. We can specify this, “all the patt erns of living and behavior which are special to small units within a large and structurally developed society.” ( Erdemli , 2002In Turkey; it’s more accurate to say that, it’s understood football when you think about sports and sport culture is football culture. This condition can not only induce cultural diversity and wealth but it also leads to a transformation into a society who likes watching sports, talking about sports (saying more precisely football rather than doing sports. Sport magazine has sur passed the sport itself. Representation of sport in media does not make a favorable contribution. Sport media invites violence with its manner of representation of news by acting with the concerns of rating and curcilation although they, at every turn, dec lare that they are against violence. Discourses which include violence, nationalism, sexism, and slang has increased in media as an extensive research also suggested ( Talimciler , 2003.Culture, is a phenomenon which is considerably about quality and accumu lation. Processes are as important as results; sometimes even more. In this sense sport is much more than the score. In a country, a sport branch can be attracting more attention than the other ones; however, Limiting sports to football, also limiting fo otball to several football clubs, and ignoring many of sports branches, those who are interested in them, and who are amateurs is an unfair and reductive approach. On the other hand; sports opportunities could not be created for millions of young and adul t people in our country

  2. Mutual Information Analyses of Neuron Selection Techniques in Synchronous Exponential Chaotic Tabu Search for Quadratic Assignment Problems

    The tabu search was implemented on a neural network with chaotic neuro-dynamics. This chaotic exponential tabu search shows great performance in solving quadratic assignment problems (QAPs). To exploit inherent parallel processing abilities of analog hardware systems, a synchronous updating scheme, where all the neurons in the network are updated at the same time, was proposed. However, several neurons may fire simultaneously with the synchronous updating. As a result, we cannot determine only one candidate for the 2-opt exchange from the many fired neurons. To solve this problem, several neuron selection methods, which select one specific neuron among the fired neurons, were proposed. These neuron selection methods improved the performance of the synchronous updating scheme. In this paper, we analyze the dynamics of the chaotic neural network with the neuron selection methods by means of the spatial and temporal mutual information. Through the analyses, the network solution search dynamics of the exponential chaotic tabu search with different neuron selection methods are evaluated.

    Sport participation is especially important for patients with asthma in that it decreases psychosocial and physiological problems associated with inactivity. However, adolescents with asthma seem to participate less in sports compared to their non-asthmatic peers. The current study tested the direct associations between maternal sport-specific factors and sport club participation of early adolescents with asthma and the indirect effect through adolescent's sport-specific cognitions. During home visits, 261 adolescents (aged 10-15) completed questionnaires about self-efficacy, beliefs regarding sport participation, and their actual sport club participation. Their mothers reported their sport-specific support, beliefs about offspring's and own sport participation, their own levels of physical activity, and their self-efficacy to stimulate offspring to participate in sports. Path analyses were used to examine the direct and indirect associations of maternal sport-specific factors with adolescents sport club participation via adolescent sport-specific cognitions. Analyses showed that maternal sport-specific support (β = 0.20, P = 0.007) and self-efficacy to stimulate offspring to participate in sports (β = 0.20, P = 0.027) related positively to adolescents' sport club participation. Adolescents' self-efficacy (indirect effect = 0.09, SE = 3.01, P sport and adolescents' participation in sport clubs. Maternal sport-specific factors related to adolescents' sport club participation directly and indirectly through adolescents' sport-specific cognitions.

    Background: Capitellar osteochondritis dissecans (OCD) is commonly managed surgically in symptomatic adolesent throwers and gymnasts. Little is known about the impact that surgical technique has on return to sport. Purpose: To evaluate the clinical outcomes and return-to-sport rates after operative management of OCD lesions in adolescent athletes. Study Design: Systematic review; Level of evidence, 4. Methods: The PubMed, CINAHL, EMBASE, SPORTDiscus (EBSCO), and Cochrane Central Register of Controlled Trials databases were queried for studies evaluating outcomes and return to sport after surgical management of OCD of the capitellum. Two independent reviewers conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies reporting patient outcomes with return-to-sport data and minimum 6-month follow-up were included in the review. Results: After review, 24 studies reporting outcomes in 492 patients (mean age ± SD, 14.3 ± 0.9 years) were analyzed. The overall return-to-sport rate was 86% at a mean 5.6 months. Return to the highest preoperative level of sport was most common after osteochondral autograft procedures (94%) compared with debridement and marrow stimulation procedures (71%) or OCD fixation surgery (64%). Elbow range of motion improved by 15.9° after surgery. The Timmerman-Andrews subjective and objective scores significantly improved after surgery. Complications were low (<5%), with 2 cases of donor site morbidity after osteoarticular autograft transfer (OAT) autograft harvest. The most common indications for reoperation were repeat debridement/loose body removal. Conclusion: A high rate of return to sport was observed after operative management of capitellar OCD. Patients were more likely to return to their highest level of preoperative sport after OAT autograft compared with debridement or fixation. Significant improvements in elbow range of motion and patient outcomes are

    Advances in technology have allowed research in cognitive neuroscience to contribute significantly to the discipline of sport psychology. In most cases, the research has become more rigorous and has directed current thinking on the mechanisms subserving a number of psychological theories and models of practice. Currently, the three most common neuroscience techniques informing sport and exercise research are electroencephalography, transcranial magnetic stimulation and functional magnetic resonance imaging. In this review, we highlight and discuss the contributions to sport psychology that have been made in recent years by applying these techniques, with a focus on the development of expertise, motor cognition, motor imagery and action observation.

    Full Text Available Purpose. We investigated acute endophthalmitis incidence following cataract surgery vis-a-vis the current technological and postoperative care changes in higher and lower socioeconomic categories of patients in South India. Methods. In a retrospective case control study, we analyzed 62 cases of acute endophthalmitis and 5 controls for each endophthalmitis case from 46,095 cataract surgeries done between years 1993 and 1998. The time period covered the transition of surgical technique and after care. In addition, we analyzed systemic diseases, surgeon factor, habitat, and socioeconomic status. Results. Clinical and culture positive endophthalmitis incidence were 0.13% and 0.07%, respectively. Differential incidence of 0.10% and 0.17% for in- and ambulatory care surgeries, respectively, was close to statistical significance (=0.054. Lower economy category ambulatory patients had higher risk of infection. Conclusion. Ambulatory cataract surgery carried additional risk for post-operative infection in lower socioeconomic group. Improved health education could ensure greater safety.

    2013-09-01

    Full Text Available Community-based management research is a collaborative effort between management, academics and communities in need with the specific goal of achieving social change to foster social justice. Because it is designed to promote and validate joint methods of discovery and community-based sources of knowledge, community-based management research has several unique characteristics, which may affect its execution. This article describes the process of a community-based management research project which is descriptive in nature and uses quantitative techniques to examine school efficiencies in low-income communities in a developing country – Bolivia. The article describes the partnership between a US-based university and a Bolivian not-for-profit organisation, the research context and the history of the research project, including its various phases. It focuses on the (yet unpublished process of the community-based research as opposed to its content (which has been published elsewhere. The article also makes the case that the robust partnership between the US-based university and the Bolivian NGO has been a determining factor in achieving positive results. Strengths and limitations are examined in the hope that the experience may be helpful to others conducting descriptive quantitative management research using community-engaged frameworks in cross-cultural settings. Keywords: international partnership, community-engaged scholarship, education efficiency, multicultural low-income education.

    Full Text Available Particles formed upon photo-oxidation of CH2I2 and particles of I2O5 and HIO3 have been studied using a Volatilisation and Humidification Tandem Differential Mobility Analyser (VH-TDMA system. Volatilization and hygroscopic behaviour have been investigated as function of temperature (from 25 to 400°C, humidity (RH from 80 to 98%, initial aerosol sizes (from 27 to 100 nm mobility diameter and in nitrogen or air as the sheath gasses. The volatility behaviour of particles formed upon photo-oxidation of CH2I2 is more similar to that of HIO3 particles in a filtered sheath air than in nitrogen, with the particle shrinkage occurring at 190°C and accompanied by hygroscopic growth. Despite its high solubility, HIO3 was found not to be hygroscopic at room temperature with no significant growth displayed until the thermodenuder temperature reached 200°C or above when the particles have transformed into I2O5. Diiodopentaoxide (I2O5 particles exhibit relatively low hygroscopic growth factors of 1.2–2 in the humidity range investigated. Scanning Electron Microscopy (SEM of particles formed upon photo-oxidation of CH2I2 shows that their primary elemental components were iodine and oxygen in a stoichiometric ratio of approximately 1:2 with 10% error. Both Raman spectra and SEM show poor crystallinity for all the aerosols produced.

Os resultados, expostos e discutidos a partir de três categorias articuladoras, revelam que o esporte, em articulação com a técnica e a juventude, temas que frequentemente aparecem inscritos no mesmo nexo interpretativo em Ortega, pode ser lido no contexto de sua obra como uma espécie de metáfora significadora do caráter lúdico e não-utilitarista da vida humana, interpretação em conformidade com as grandes questões que delineiam o núcleo central do arcabouço filosófico orteguiano. Conclui-se destacando o pioneirismo das análises de Ortega sobre o nascente processo de expansão do esporte e sua crescente importância social nas primeiras décadas do século XX, assim como a necessidade de se considerar a juventude como problemática filosófica e sociológica.This paper presents results of a research whose aim was to investigate sport by the Spanish Philosopher José Ortega y Gasset. The sources are the twelve volumes of his Complete Writings.

    2012-04-01

    Full Text Available Direct comparison of air–sea CO2 fluxes by open-path eddy covariance (OPEC and closed-path eddy covariance (CPEC techniques was carried out over the equatorial Pacific Ocean. Previous studies over oceans have shown that the CO2 flux by OPEC was larger than the bulk CO2 flux using the gas transfer velocity estimated by the mass balance technique, while the CO2 flux by CPEC agreed with the bulk CO2 flux. We investigated a traditional conflict between the CO2 flux by the eddy covariance technique and the bulk CO2 flux, and whether the CO2 fluctuation attenuated using the closed-path analyser can be measured with sufficient time responses to resolve small CO2 flux over oceans. Our results showed that the closed-path analyser using a short sampling tube and a high volume air pump can be used to measure the small CO2 fluctuation over the ocean. Further, the underestimated CO2 flux by CPEC due to the attenuated fluctuation can be corrected by the bandpass covariance method; its contribution was almost identical to that of H2O flux. The CO2 flux by CPEC agreed with the total CO2 flux by OPEC with density correction; however, both of them are one order of magnitude larger than the bulk CO2 flux.

    Total System Performance Assessment (TSPA) is used as a key decision-making tool for the potential geologic repository for high level radioactive waste at Yucca Mountain, Nevada, USA. Because of the complexity and uncertainty involved in a post-closure performance assessment, an important goal is to produce a transparent document describing the assumptions, the intermediate steps, the results, and the conclusions of the analyses. An important objective for a TSPA analysis is to illustrate confidence in performance projections of the potential repository given a complex system of interconnected process models, data, and abstractions. The methods and techniques used for the recent TSPA analyses demonstrate an effective process to portray complex models and results with transparency and credibility.

    2016-10-01

    Mixed martial arts (MMA) is a combat sport underpinned by techniques from other combat disciplines, in addition to strategies unique to the sport itself. These sports can be divided into two distinct categories (grappling or striking) based on differing technical demands. Uniquely, MMA combines both methods of combat and therefore appears to be physiologically complex requiring a spectrum of mechanical and metabolic qualities to drive performance. However, little is known about the physiological characteristics that distinguish higher- from lower-level MMA athletes. Such information provides guidance for training interventions, performance testing and talent identification. Furthermore, while MMA incorporates techniques from both grappling and striking sports, it is unknown precisely how these disciplines differ physiologically. Understanding the relationship between higher-level competitors in grappling and striking combat sports can provide further insight into the development of the optimal performance profile of a higher-level MMA athlete. This article aims to analyse the scientific literature on MMA and the primary combat sports underpinning it to determine the physiological adaptations that distinguish superior competitors, with a view to defining the optimal physiological profile for higher-level MMA performance. Furthermore, this article will explore the differences in these capabilities between grappling- and striking-based combat sports in the context of MMA. A literature search was undertaken via PubMed, Web of Science, SportDiscus and Google Scholar. The following sports were included for systematic review based on their relevance to MMA: mixed martial arts, boxing, Brazilian jiu-jitsu, judo, karate, kickboxing, Muay Thai and wrestling. The inclusion criteria allowed studies that compared athletes of differing competition levels in the same sport using a physiological performance measure. Only male, adult (aged 17-40 years), able-bodied competitors

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

    Full Text Available Without any doubt, sport has become a major consumer market, either we discuss about practicing any kind of sport at professional or amateur level, or we are just interested by a competition, sport organization or an athlete as a regular consumer. From this last perspective, we can distinguish between two types of behaviors, respectively the spectator and the supporter or fan. Each of these two typologies has its own characteristics which define, in a significant manner, the consumer behavior. A correct understanding and management of this phenomenon, of the factors that influence the attitudes and the decisions taken by the respective consumer, of the display manner for the consumer behavior have a major importance from the management and marketing point of view. This paper focuses on the football consumer and describes, first of all, the main characteristics of each of the typologies mentioned above from this perspective, presenting also the reasons for their transition from passive supporter to fan. Another issue we approach in the current paper refers to the changes appeared in the consumer behavior when the market segment is represented by those supporters whose teams are either relegated or liquidated, which is a global phenomenon in the football area. Having in mind this aspect and taking into consideration the influence of media (TV, press, Internet, social media etc, some individual benchmarks that influence those consumer’s behavior are identified within the context of the general typologies previously mentioned. These influences help the consumer to obtain benefits or satisfaction similar to those already lost. The findings may be used in further research focused on that particular market segment and could provide the necessary support data for further development of proper techniques and tools for reshaping and changing the respective consumer behavior.

    When an athlete is injured, the primary focus of the sports medicine team is to treat the physical effects of the injury. However, many injured athletes experience negative psychological responses that should also be addressed throughout the rehabilitation process. Sports medicine professions should use psychosocial skills to help decrease the negative consequences of the injury, such as fear of reinjury, anxiety, depression, and adherence to rehabilitation. These psychosocial skills include goal setting, imagery, relaxation techniques, motivation, and self-talk. This article addresses the negative consequences of injury, psychosocial skills used to aid in the rehabilitation process, and clinical implications of the psychological aspects of rehabilitation in sport.

    2009-11-01

    To assess the effect of technology on sport, the performance statistics for four disciplines were analysed: the 100-m sprint, pole vault, javelin, and cycling. The concept of a performance improvement index was developed to allow comparison between athletes and between sports with a higher index indicating a greater improvement in the sport. The following performance improvement indices were found: 100-m sprint, 24% over 108 years; pole vault, 86% over 94 years; javelin, 95% over 76 years; 4-km individual pursuit, 35% over 32 years; one-hour cycling record, 221% over 111 years. Around 4% of the index for the sprint was attributed to tighter, aerodynamic clothing, suggesting that general athletic improvement in sprint-type events has been around 20%. Technological developments in simple equipment such as the pole vault or javelin were seen to affect the index by around 30%, while the index associated with aerodynamic improvements in the one-hour record was around 100%. It is concluded that the performance improvement index could be extended to amateur as well as elite sport where distance or time is used as a measure of performance.

    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.

    2008-01-01

    Efforts at player motion tracking have traditionally involved a range of data collection techniques from live observation to post-event video analysis where player movement patterns are manually recorded and categorized to determine performance effectiveness. Due to the considerable time required to manually collect and analyse such data, research has tended to focus only on small numbers of players within predefined playing areas. Whilst notational analysis is a convenient, practical and typically inexpensive technique, the validity and reliability of the process can vary depending on a number of factors, including how many observers are used, their experience, and the quality of their viewing perspective. Undoubtedly the application of automated tracking technology to team sports has been hampered because of inadequate video and computational facilities available at sports venues. However, the complex nature of movement inherent to many physical activities also represents a significant hurdle to overcome. Athletes tend to exhibit quick and agile movements, with many unpredictable changes in direction and also frequent collisions with other players. Each of these characteristics of player behaviour violate the assumptions of smooth movement on which computer tracking algorithms are typically based. Systems such as TRAKUS, SoccerMan, TRAKPERFORMANCE, Pfinder and Prozone all provide extrinsic feedback information to coaches and athletes. However, commercial tracking systems still require a fair amount of operator intervention to process the data after capture and are often limited by the restricted capture environments that can be used and the necessity for individuals to wear tracking devices. Whilst some online tracking systems alleviate the requirements of manual tracking, to our knowledge a completely automated system suitable for sports performance is not yet commercially available. Automatic motion tracking has been used successfully in other domains outside

  19. Sports physicians and the doping crisis in elite sport.

    Hoberman, John

    2002-07-01

    The participation of sports physicians in the "doping" of athletes with banned drugs can be documented as far back as the 1890s. Concern about the ethics and safety of doping elite athletes appeared during the 1920s and 1930s as sport became an increasingly important form of popular culture. While organized medicine has opposed doping as a matter of policy at least since the 1950s, sports physicians have never adequately confronted the conflicts of interest that arise when they choose to work with elite athletes whose first priority is performance rather than with healing in the traditional sense. Confronted with the demands of their athlete-clients, sports physicians have divided into two factions regarding the wisdom and propriety of administering doping drugs to athletes. While most physicians are, in all likelihood, unwilling to violate laws, regulations, and medical standards by doping athletes, a significant minority of doctors has used one or more arguments to justify doping athletes: drugs are necessary to compete effectively; athletes should be free to medicate themselves as they please; drugs do not differ essentially from other performance-enhancing techniques or equipment; and medically supervised doping is safer than self-medication by athletes. Physicians can also rationalize doping as an occupational requirement of some professional athletes. In summary, physicians have played a significant, and largely unacknowledged, role in the doping of many elite athletes over the past 50 years.

    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 relationship between sport and technology is close and can be both fruitful and destructive. Technology has a constitutive function in sport as it makes the activity possible and it can enhance performance as well as the sporting experience. The use of football boots is clearly more comfortable...... and effective than playing in bare feet in a game of football. However, sport challenges its athletes by demanding the employment of less efficient means rather than more efficient means in pursuit of sport specific goals. Therefore technology can potentially subtract from the sporting experience and even...... threaten the internal logic of sport. If as an example very efficient hail cartridges were allowed for use in double trap shooting it would reduce the skills required to excel at that discipline reducing its value for participants and spectators alike.

In the first part we present developments inside left-oriented theories of sport, especially the need for critical research based on specific aspects of criticism of political economy. We then review brief the current situation in contemporary sport, mainly about parallel evolution of the capitalist commodification of sport and the emergence of the application of biopolitically directed practices, where we have tried to implement a short overview of Foucault’s concepts in the field of sport studies. The third part deals with the connection between Paolo Virno’s biopolitical studies and Marx’s labour power. In conclusion, we raise the possibility of applying Virno’s settings to treat sport practice in the context of its appropriation by capitalism, characterised by the intensification of strategies and techniques for controlling sportsman life. According to Virno’s settings we have tried to show influence to a life of sportsman in the aim of bio-potency, the ability/power to produce a labour force, while this force is treated like labour exchanged in the market in the context of capitalist commodification of modern sport.

As applied to the school setting, and with special reference to sport coaching, this article deals with the five fundamental elements of the law of delict that influence and inform the execution of the duty of care of the educator-coach. This article pays special attention to the legal aspects related to the security, on the one hand, of the learners as participants, but also the educator-coach in his or her respective roles as coach, organiser of sport events, referee and sport official on the other.The basic research question is: To what extent can educator-coaches increase their own security by ensuring safer participation of learners? How can these educators prevent or minimise the occurrence of serious injuries during practices (as coaches and during meetings, contests or matches (as officials, such as being referees? A certain amount of risk is typical of and inherent to most types of sports, especially those that involve physical contact or in which potentially dangerous implements are used. In contrast, many learners are coached by educators that do not necessarily have enough experience, skills or knowledge regarding the more advanced techniques of the specific sports code. This contrast between the inherent risks and the lack of expertise of many educator-coaches creates an amount of insecurity for both the participants and the coaches.This article includes a discussion of the application of the five fundamental elements of the South African law of delict to school sports coaching. To illustrate the ways in which courts consider sports law issues, examples from court cases related to different types of sports are analysed, and, where applicable, cases from other countries and from outside the sphere of education are also included. This discussion is followed by an overview of those legal provisions that impact on sports participation at school.The legal duty of care

    Full Text Available The model of modern sports performance asks for certain graduation in the treatment of its efficiency. Besides the coaching model, what matters is the genetic potential of the child or junior, and particularly the selection of the young talented athlete identified at the proper time and included in a proper training system, in full harmony with the education process. The sports output is determined by the simultaneous action of several factors whose influences are different. At present, there is a tendency to improve those factors on which rely sports outcomes and that need to be analysed and selected. Psychic capacity is a major factor, and mental control – the power to focus, motor intelligence, motor memory, creativity, and tactical skills play a major role in an athlete’s style. This study aims at showing the measure in which motor memory allows early and reliable diagnosis of future performance. The subjects selected are components of the mini-basket team of the Sports Club “Sport Star” from Timisoara, little girls that have played basketball since 1st grade in their free time (some of the girls have played it for four years. The research was carried out during a competitive year; we monitored the subjects both during coach lessons and minibasketball championship. To assess motor memory, we used the “cerebral module” consisting in memorising a complex of technical and tactical elements and applying them depending on the situation in the field. The research also involved monitoring the subjects in four directions considered defining in the assessment of the young athletes: somatic data, physical features, basketball features and intellectual potential. Most parameters point out a medium homogeneity of the group, except for height and commitment (great homogeneity. Half of the athletes of the tested group are above the mean of the group, which allows guiding them towards higher coaching forms (allowing them to practice basketball

    Chronic pain of the inguino-crural region or "pubalgia" explains the 0.5-6.2% of the consultations by athletes. Recently, areas of weakness in the posterior wall called "sports hernias," have been identified in some of these patients, capable of producing long-standing pain. Several authors use different image methods (CT, MRI, ultrasound) to identify the lesion and various techniques of repair, by open or laparoscopic approaches, have been proposed but there is no evidence about the superiority of one over others due to the difficulty for randomizing these patients. In our experience, diagnosis was based on clinical and ultrasound findings followed by laparoscopic exploration to confirm and repair the injury. The present study aims to assess the performance of our diagnostic and therapeutic management in a series of athletes affected by "pubalgia". 1450 athletes coming from the orthopedic office of a sport medicine center were evaluated. In 590 of them (414 amateur and 176 professionals) sports hernias were diagnosed through physical examination and ultrasound. We performed laparoscopic "TAPP" repair and, thirty days after, an assessment was performed to determine the evolution of pain and the degree of physical activity as a sign of the functional outcome. We used the U Mann-Whitney test for continuous scale variables and the chi-square test for dichotomous variables with p hernias. We found 84 "sport hernias" in 769 patients with previous diagnosis of adductor muscle strain (10.92%); on the other hand, in 127 (21.52%) of our patients with "sport hernias" US detected concomitant injuries of the adductor longus tendon, 7 of which merited additional surgical maneuvers (partial tenotomy). Compared with the findings of laparoscopy, ultrasound had a sensitivity of 95.42% and a specificity of 100%; the positive and negative predictive values were 100 and 99.4% respectively. No postoperative complications were reported. Only seven patients suffered recurrence of pain

    2015-02-01

    Sport psychology education has been shown to have a positive impact on the practice of sport injury rehabilitation professionals (SIRPs). The purpose of this paper is to review recommendations relating to such education. The paper presents a review of existing literature relating to the content and mode of delivery for a sport psychology education programme for SIRPs. The review seeks to address four questions: (1) What topic areas do researchers suggest should be integrated into the sport psychology education of SIRPs? (2) What topic areas are currently being recommended by professional bodies? (3) What are the findings of research examining the impact of sport psychology education on SIRPs? and (4) What do researchers recommend to be the most appropriate mode of delivery for sport psychology education for SIRPs? The findings of the review suggest that in order to maximise adherence amongst already qualified SIRPs sport psychology education should be delivered in a flexible short duration package. Additionally three broad areas that sport psychology education should cover emerged: (1) understanding of the psychological impact of injury, (2) interventions and psychological skills/techniques, and (3) referral and professional boundaries. This has important implications for the future training of SIRPs.

    2014-06-01

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

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

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

However, modern sports medicine has emerged with the goal of improving performance and preventing injury, and the concept of the "team physician" has become an integral part of athletic culture. With this distinction come unique ethical challenges because the customary ethical norms for most forms of clinical practice, such as confidentiality and patient autonomy, cannot be translated easily into sports medicine. The particular areas of medical ethics that present unique challenges in sports medicine are informed consent, third parties, advertising, confidentiality, drug use, and innovative technology. Unfortunately, there is no widely accepted code of sports medicine ethics that adequately addresses these issues.

    Jéssica Natuline Ianof

    Full Text Available ABSTRACT Traumatic brain injury (TBI is a major cause of lifelong disability and death worldwide. Sport-related traumatic brain injury is an important public health concern. The purpose of this review was to highlight the importance of sport-related concussions. Concussion refers to a transient alteration in consciousness induced by external biomechanical forces transmitted directly or indirectly to the brain. It is a common, although most likely underreported, condition. Contact sports such as American football, rugby, soccer, boxing, basketball and hockey are associated with a relatively high prevalence of concussion. Various factors may be associated with a greater risk of sport-related concussion, such as age, sex, sport played, level of sport played and equipment used. Physical complaints (headache, fatigue, dizziness, behavioral changes (depression, anxiety, irritability and cognitive impairment are very common after a concussion. The risk of premature return to activities includes the prolongation of post-concussive symptoms and increased risk of concussion recurrence.

    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.

    This article synthesizes existing literature to provide a summary of the ethical issues concerning patient confidentiality in sport. It outlines the medical principle of confidentiality and identifies cross-cultural ethicolegal variations that shape its implementation. Clinicians' multiple obligations, physical environments, and practice and policy contexts are discussed, and research detailing experiences of maintaining patient confidentiality in sport is reviewed. Policy recommendations for enhancing compliance with this ethical principle are summarized. It is argued that the context of sport exacerbates pressures on clinicians to break patient confidentiality, breaches occur regularly, and interventions are required to enhance ethical compliance in sports medicine.

    Background: Research productivity is considered an important factor in academic advancement in sports medicine. No study to date has evaluated academic productivity and correlates of academic rank for sports medicine fellowship faculty. Purpose: To describe the academic productivity of American Orthopaedic Society for Sports Medicine (AOSSM) fellowship program faculty and to determine the association between academic productivity, fellowship characteristics, and academic rank. Study Design: Descriptive epidemiology study. Methods: Characteristics of orthopaedic sports medicine fellowship programs were obtained from the AOSSM and program websites. Metrics of academic productivity (Hirsch index [h index], I-10 index, publications, citations, and number of publications in several journals) were obtained from Scopus. Statistical analyses were conducted to determine whether academic productivity differs with fellowship attributes and academic rank. Results: A total of 90 AOSSM sports medicine fellowship programs with 610 associated faculty members were identified. Faculty were predominantly male (94%), at academic medical centers (74%), members of AOSSM (71%), and sports medicine–fellowship trained (84%). Faculty had a median of 18 (range, 0-684) publications overall, including a median of 3 (range, 0-161) publications since 2012.

    Balagué, N; Torrents, C; Hristovski, R; Kelso, J A S

    2017-02-01

    The aim of the paper is to point out one way of integrating the supposedly incommensurate disciplines investigated in sports science. General, common principles can be found among apparently unrelated disciplines when the focus is put on the dynamics of sports-related phenomena. Dynamical systems approaches that have recently changed research in biological and social sciences among others, offer key concepts to create a common pluricontextual language in sport science. This common language, far from being homogenising, offers key synthesis between diverse fields, respecting and enabling the theoretical and experimental pluralism. It forms a softly integrated sports science characterised by a basic dynamic explanatory backbone as well as context-dependent theoretical flexibility. After defining the dynamic integration in living systems, unable to be captured by structural static approaches, we show the commonalities between the diversity of processes existing on different levels and time scales in biological and social entities. We justify our interpretation by drawing on some recent scientific contributions that use the same general principles and concepts, and diverse methods and techniques of data analysis, to study different types of phenomena in diverse disciplines. We show how the introduction of the dynamic framework in sport science has started to blur the boundaries between physiology, biomechanics, psychology, phenomenology and sociology. The advantages and difficulties of sport science integration and its consequences in research are also discussed.

  8. Sports Video Segmentation using Spectral Clustering

    Full Text Available With the rapid development of the computer and multimedia technology, the video processing technique is applied to the field of sports in order to analyze the sport video. For sports video analysis, how to segment the sports video image has become an important research topic. Nowadays, the algorithms for video image segmentation mainly include neural network, K-means and so on. However, the accuracy and speed of these algorithms for moving objects segmentation are not satisfied, and easily influenced by the irregular movement of the object and illumination, etc. In view of this, this paper proposes an algorithm for object segmentation in sports video image sequence, based on the spectral clustering. This algorithm simultaneously considers the pixel level visual feature and the edge information of the neighboring pixels to make the calculation of similarity is more intuitive and not affected by factors such as image texture. When clustering the image feature, the proposed method: (1 preprocesses video image sequence and extracts the image feature. (2Using weight function to build and calculate the similar matrix between pixels. (2 Extract feature vector. (3 Perform clustering using spectral clustering algorithm to segment the sports video image. The experimental results indicate that the method proposed in this paper has the advantages, such as lower complexity, high computational effectiveness, low computational amount, and so on. It can get better extraction effects on video image

    Measurements of Pb isotope ratios in ice containing sub-pg g(-1) concentrations are easily compromised by contamination, particularly where limited sample is available. Improved techniques are essential if Antarctic ice cores are to be analysed with sufficient spatial resolution to reveal seasonal variations due to climate. This was achieved here by using stainless steel chisels and saws and strict protocols in an ultra-clean cold room to decontaminate and section ice cores. Artificial ice cores, prepared from high purity water were used to develop and refine the procedures and quantify blanks. Ba and In, two other important elements present at pg g(-1) and fg g(-1) concentrations in Polar ice, were also measured. The final blank amounted to 0.2+/-0.2 pg of Pb with (206)Pb/(207)Pb and (208)Pb/(207)Pb ratios of 1.16+/-0.12 and 2.35+/-0.16, respectively, 1.5+/-0.4 pg of Ba and 0.6+/-2.0 fg of In, most of which probably originates from abrasion of the steel saws by the ice. The procedure was demonstrated on a Holocene Antarctic ice core section and was shown to contribute blanks of only approximately 5%, approximately 14% and approximately 0.8% to monthly resolved samples with respective Pb, Ba and In concentrations of 0.12 pg g(-1), 0.3 pg g(-1) and 2.3 fg g(-1). Uncertainties in the Pb isotopic ratio measurements were degraded by only approximately 0.2%.

Our research aimed to describe the association between SAH and sports and to identify the types of sports that were more frequently found as precipitating factors in a tertiary single-centre SAH register. Methods: We retrieved information from a prospectively collected SAH registry and reviewed discharge notes of acute SAH patients admitted to the Stroke Unit of Hospital de Santa Maria, Lisbon, between 1995 and 2014. Results: Out of 738 patients included in the analysis, 424 (57.5% cases of SAH were preceded by physical activity. Nine cases (1.2% were associated with sports, namely running (2 cases, aerobics (2 cases, cycling, body balance, dance, surf and windsurf. Patients with SAH while practicing sports were younger than controls (average age 43.1 vs. 57.0 years; p = 0.007. In 1 patient, there was a report of trauma to the neck. Patients in the sports group only had Hunt and Hess scale grades 1 (11.1% or 2 (88.9% at admission, while patients in the control group had a wider distribution in severity. Conclusions: Our findings indicate that SAH precipitated by sports is not very frequent and is uncommonly related to trauma. Patients who suffered SAH associated with sports were younger and apparently had a milder clinical presentation.

    Sports arrhythmia has gained wide attention with the mediatization of the death of famous sports stars. Sport strongly modifies the structure of the heart with the development of left ventricular hypertrophy which may be difficult to differentiate from that due to doping. Intense training modifies also the resting electrocardiogram with appearance of signs of left ventricular hypertrophy whereas resting sinus bradycardia and atrioventricular conduction disturbances usually reverts upon exertion. Accordingly, arrhythmia may develop ranging from extrasystoles to atrial fibrillation and even sudden death. Recent data suggest that if benign arrhythmia may be the result of the sole intense training and are reversible, malignant ventricular arrhythmia and sudden death mostly occur in unknown structural heart disease. Hypertrophic cardiomyopathy is amongst the most frequent post mortem diagnosis in this situation. Doping is now present in many sports and further threatens the athlete in the safe practice of sport.

    Full Text Available Mindfulness in sports is a recent field. While sport psychology relied mainly on “second wave” cognitive-behavioural interventions for the last four decades, a new approach has recently been developed in sport psychology including mindfulness: a “third wave” approach. This new approach assumes that ideal performance is a state that is not based on self-control or change in behaviour, but rather a state that arises from recognition and acceptance of thoughts, emotions and bodily sensations. Practicing mindfulness allows learns to observe and accept the thoughts, emotions, and body sensations, without making any attempt to eliminate or modify them. This paper reviews the main programs of mindfulness in sport performance both from the “third wave”: Mindful Sport Performance Enhancement (MSPE and Mindfulness-Acceptance-Commitment(MAC.

    Sports vision encompasses the visual assessment and provision of sports-specific visual performance enhancement and ocular protection for athletes of all ages, genders and levels of participation. In recent years, sports vision has been identified as one of the key performance indicators in sport. It is built on four main cornerstones: corrective eyewear, protective eyewear, visual skills enhancement and performance enhancement. Although clinically well established in the US, it is still a relatively new area of optometric specialisation elsewhere in the world and is gaining increasing popularity with eyecare practitioners and researchers. This research is often multi-disciplinary and involves input from a variety of subject disciplines, mainly those of optometry, medicine, physiology, psychology, physics, chemistry, computer science and engineering. Collaborative research projects are currently underway between staff of the Schools of Physics and Computing (DIT) and the Academy of Sports Vision (RAU).

    Although the medical complications of sports are usually traumatic in nature, infectious hazards also arise. While blood-borne pathogens such as HIV, hepatitis B, and hepatitis C, cause significant illness, the risk of acquiring these agents during sporting activities is minimal. Skin infections are more commonplace, arising from a variety of microbial agents including bacterial, fungal, and viral pathogens. Sports involving water contact can lead to enteric infections, eye infections, or disseminated infections such as leptospirosis. Mumps, measles, and influenza are vaccine-preventable diseases that have been transmitted during sporting events, both in players and in spectators. Prevention is the key to many of these infections. Players should be vaccinated and should not participate in sports if their infection can be spread by contact, airborne, or droplet transmission.

    Meek, Rosie; Lewis, Gwen

    2012-01-01

    The existing evidence base and policy context of sports-based prisoner health promotion is evaluated, and an original analysis of current provision and best practice in delivering sport to address physical, mental and substance misuse needs among prisoners across the secure estate in England and Wales is presented, with a focus on the variability of provision across different prison establishments. Inspectorate reports published by Her Majesty's Inspectorate of Prisons (n=184) were analysed to assess the extent to which health promotion objectives are being implemented through physical education in prisons across England and Wales. Examples of innovative sport-based health promoting programmes are drawn upon in order to illustrate principles of best practice. Despite health promotion being engrained in existing policy, the degree to which physical, mental health and substance misuse needs are addressed through sport in prison remains highly variable and locally contingent across the secure estate, although examples of innovative practice are evident. For sport to promote prisoner health most effectively, tailored sports provision should be embedded within multi-modal interventions which draw on internal and external partnerships and promote opportunities for ongoing sporting participation. Further research is required to delineate principles of best practice applicable to discrete prisoner populations. Sport can play a key role in addressing a multitude of prisoner health needs whilst contributing to achieving "healthy prison" objectives in practice. Sport and physical activity clearly offers a valuable way of motivating prisoners to engage in health promoting initiatives.

    2012-01-01

    Full Text Available Disability sport is growing around the world with momentum and is described as a “movement” (Bailey, 2008; DePauw & Gavron, 2005. While there are more similarities than differences with sport management for able-bodied athletes and those with disabilities, there are additional needs and considerations for persons with disabilities (DePauw & Gavron, 2005. The noticeable visibility of individuals with disabilities in society, including sport, raises concerns about the degree to which sport management academic programs have modified their curricula to ensure that individuals working in the sport management field are prepared to deal with theuniqueness of disability sport. This paper (a discusses theoretical perspectives toward understanding and thinking about disability, (b explores ways to enhance sport management curricula through infusion of disability sport, (c reflects upon current social practices for curriculum integration of athletes with disabilities in sport, and (d acknowledges infusion of disability sport businesses, organizations and events.

    Using Australian Football League (AFL) matches as a case study, we investigated the frequency, length and content of marketing strategies for sports betting during two specific settings: 1) at stadiums during four live matches; and 2) during eight televised broadcasts of matches. Census of sports betting marketing during Round 12 of the 2011 AFL premiership season. Per match, there was an average of 58.5 episodes (median 49.5, s.d 27.8) and 341.1 minutes (median 324.1 minutes and s.d 44.5) of sports betting marketing at stadiums, and 50.5 episodes (median 53.5, s.d 45.2) and 4.8 minutes (median 5.0 minutes, s.d 4.0) during televised broadcasts. A diverse range of marketing techniques were used to: a) embed sports betting within the game; b) align sports betting with fans' overall experience of the game; and c) encourage individuals to bet live during the game. There were very few visible or audible messages (such as responsible gambling or Gambler's Help messages) to counter-frame the overwhelmingly positive messages that individuals received about sports betting during the match. This study raises important questions about the impacts of saturation, integrated and impulse gambling marketing strategies in sporting matches. Future research should explore: 1) how wagering industry marketing strategies may affect the attitudes and behaviours of community sub-groups (e.g. young male sports fans, and children); and 2) which public health and policy strategies, including regulation and harm minimisation messaging, will be effective in responding to wagering industry marketing strategies during sporting matches. © 2012 The Authors.

    The report of the National Academy of Medicine named "Sport and Health" underlines the medical, social and educational dimensions of sporting activities. Various kinds of sporting practices are described: they concern the approximately 7,000 high level athletes, around 8,000 professional (licensed) sportsmen, and sporting club members (approximately 15 millions people). A large number of amateurs do not practice in any structure and therefore are neither managed in their activities nor medically followed. Some characteristics of sporting practice at various stages of life have been documented. Around 50% of the teenagers from 12 to 17 years have a sporting practice out-of-school besides the weekly three hours applied at school or college; however, the withdrawal of sporting practice by a high number of teenagers results in a sedentary lifestyle with overweight and obesity, major risks factors for health. Elderly people take a profit from a regular and medically controlled physical activity. Functional capacities are thus improved, cardiovascular risks factors among other, which results in better quality of life of the aged and delays their dependence. The benefit upon public health of sporting practice has been pointed out in the primary prevention of cardiovascular and respiratory diseases, osteoporosis, obesity, diabetes, breast and colon cancer, and mood disturbances. It is currently well acknowledged that sporting practice is an important component of public health in both primary and secondary prevention of many diseases.

Whether you refer to betting a few days in advance of the sporting event or live betting, both options have been taken into consideration. By using a clustering algorithm for analyzing both the database containing events from football matches and the odds given by bookmakers, we have obtained graphs indicating the probabilities associated with analyzed events. Given the purely informative aspect of the current paper, we have only analyzed the number of corners from a match.

    2016-01-01

    In view of the changes in and growing variety of sports-related occupations, it is highly relevant for educational institutions to know how well the educational contents of their sport science courses meet the professional requirements. This study analyses the relationship between the competencies acquired through academic sports science courses and the requirements of the relevant jobs in Switzerland. The data for this empirical analysis were drawn from a sample of n = 1054 graduates of different academic sport science programmes at all eight Swiss universities. The results show that academic sport science courses primarily communicate sports-specific expertise and practical sports skills. On the other hand, most graduates consider that the acquisition of interdisciplinary competencies plays a comparatively minor role in sport science education, even though these competencies are felt to be an important requirement in a variety of work-related environments and challenges.

    The precise geological mapping is one of the most important issues in geological studies. Documenting the spatial distribution of geological bodies and their contacts play a crucial role on interpreting the tectonic evolution of any region. Although the traditional field techniques are still accepted to be the most fundamental tools in construction of geological maps, we suggest that the integration of digital technologies to the classical methods significantly increases the resolution and the quality of such products. We simply follow the following steps in integration of the digital data with the traditional field observations. First, we create the digital elevation model (DEM) of the region of interest by interpolating the digital contours of 1:25000 scale topographic maps to 10 m of ground pixel resolution. The non-commercial Google Earth satellite imagery and geological maps of previous studies are draped over the interpolated DEMs in the second stage. The integration of all spatial data is done by using the market leading GIS software, ESRI ArcGIS. We make the preliminary interpretation of major structures as tectonic lineaments and stratigraphic contacts. These preliminary maps are controlled and precisely coordinated during the field studies by using mobile tablets and/or phablets with GPS receivers. The same devices are also used in measuring and recording the geologic structures of the study region. Finally, all digitally collected measurements and observations are added to the GIS database and we finalise our geological map with all available information. We applied this integrated method to map the Burdur-Fethiye Shear Zone (BFSZ) in the southwest Turkey. The BFSZ is an active sinistral 60-to-90 km-wide shear zone, which prolongs about 300 km-long between Suhut-Cay in the northeast and Köyceğiz Lake-Kalkan in the southwest on land. The numerous studies suggest contradictory models not only about the evolution but also about the fault geometry of this

    High school athletes are increasingly encouraged to participate in 1 sport year-round to increase their sport skills. However, no study has examined the association of competition volume, club sport participation, and sport specialization with sex and lower extremity injury (LEI) in a large sample of high school athletes. Increased competition volume, participating on a club team outside of school sports, and high levels of specialization will all be associated with a history of LEI. Girls will be more likely to engage in higher competition volume, participate on a club team, and be classified as highly specialized. Cross-sectional study. Level 3. High school athletes completed a questionnaire prior to the start of their competitive season regarding their sport participation and previous injury history. Multivariable logistic regression analyses were used to investigate associations of competition volume, club sport participation, and sport specialization with history of LEI, adjusting for sex. A cohort of 1544 high school athletes (780 girls; grades 9-12) from 29 high schools completed the questionnaire. Girls were more likely to participate at high competition volume (23.2% vs 11.0%, χ(2) = 84.7, P sport, or who were highly specialized had greater odds of reporting a previous LEI than those with low competition volume (odds ratio [OR], 2.08; 95% CI, 1.55-2.80; P sport participation (OR, 1.50; 95% CI, 1.20-1.88; P sport volume, on a club team, or being highly specialized was associated with history of LEI. Girls were more likely to participate at high volumes, be active on club teams, or be highly specialized, potentially placing them at increased risk of injury. Youth athletes, parents, and clinicians should be aware of the potential risks of intense, year-round participation in organized sports.

  6. Nutrition for winter sports.

    Meyer, Nanna L; Manore, Melinda M; Helle, Christine

    2011-01-01

    Winter sports are played in cold conditions on ice or snow and often at moderate to high altitude. The most important nutritional challenges for winter sport athletes exposed to environmental extremes include increased energy expenditure, accelerated muscle and liver glycogen utilization, exacerbated fluid loss, and increased iron turnover. Winter sports, however, vary greatly regarding their nutritional requirements due to variable physiological and physique characteristics, energy and substrate demands, and environmental training and competition conditions. What most winter sport athletes have in common is a relatively lean physique and high-intensity training periods, thus they require greater energy and nutrient intakes, along with adequate food and fluid before, during, and after training. Event fuelling is most challenging for cross-country skiers competing in long events, ski jumpers aiming to reduce their body weight, and those winter sport athletes incurring repeated qualification rounds and heats. These athletes need to ensure carbohydrate availability throughout competition. Finally, winter sport athletes may benefit from dietary and sport supplements; however, attention should be paid to safety and efficacy if supplementation is considered.

Nowadays, human evolution, including his intellectual development, proves the fact that especially the creation manpower and the employment was the solution of all life’s ambitions in society. So, the fact is that in reality, man is the most important capital of the society. Also, in an individual’s life, the practice of sport plays a significant role and that’s why the initiation, the launch and the management of sports complexes activity reveal the existence of specific management features that we will identify and explain in the current study. The aim of the research refers to the elaboration of a theoretical base of the management of the sport complexes, to the pointing of the factors that influence the efficient existence and function of a sport complex in our country and to the determination of the responsibilities that have a manager who directs successfully the activity of the sport complexes. The investigation is based on theoretical methods, such as: scientific documentation, analysis, synthesis, comparison and on empirical research methods, like: study of researched literature and observation. The results of the research indicate the fact that the profitability of a sport complex must assure a particular structure to avoid the bankruptcy risk and also, that the administration of the sport complexes activity must keep in view the reliable functions of the contemporaneous management.

    Full Text Available This article reviews developments in the use of Artificial Intelligence (AI in sports biomechanics over the last decade. It outlines possible uses of Expert Systems as diagnostic tools for evaluating faults in sports movements ('techniques' and presents some example knowledge rules for such an expert system. It then compares the analysis of sports techniques, in which Expert Systems have found little place to date, with gait analysis, in which they are routinely used. Consideration is then given to the use of Artificial Neural Networks (ANNs in sports biomechanics, focusing on Kohonen self-organizing maps, which have been the most widely used in technique analysis, and multi-layer networks, which have been far more widely used in biomechanics in general. Examples of the use of ANNs in sports biomechanics are presented for javelin and discus throwing, shot putting and football kicking. I also present an example of the use of Evolutionary Computation in movement optimization in the soccer throw in, which predicted an optimal technique close to that in the coaching literature. After briefly overviewing the use of AI in both sports science and biomechanics in general, the article concludes with some speculations about future uses of AI in sports biomechanics.

    2011-06-01

    Rhythm disorders represent the main challenge for the sport physician and cardiologist to grant the certificate of sports eligibility to the athletes. Arrhythmias that occur in athletes can be divided into two types. The most common are generally an expression of morphofunctional changes in the athlete's heart and are represented by certain forms of non-complex tachyarrhythmias and bradyarrhythmias. On the other hand you may encounter less frequently more complex arrhythmias that may be an epiphenomenon of cardiomyopathy can cause sudden death during sports activities. By collection of detailed medical history, careful examination, and in particular by the 12-lead electrocardiogram is already possible to understand the arrhythmic risk sporting population. After an analysis of main types of arrhythmias encountered in the athlete and the main diagnostic methods, this study focuses on the interplay between forms of arrhythmias, arrhythmogenic heart diseases and activity sports. Surely the increased adrenergic tone and anatomical and functional alterations sports-related favor the development of arrhythmia and sudden death risk in structural cardiomyopathies. But this is not yet resolved the question of whether sport is able to increase the incidence of ventricular arrhythmias in a normal heart. Dangerousness of the arrhythmia is variable depending on the sport is practiced with high intensity or not. Even if it is important considering the possibility of syncope in hazardous environments. Arrhythmias at risk impose the exclusion of the athlete from the practice of sport. In some cases it may be considered a drug treatment, ablation, and in rare and selected cases, the implantation of a pacemaker or an implantable defibrillator.

    Although physical activity brings a range of lifelong health benefits, it may also lead to injuries that pose a significant threat to health. It is particularly noticeable in people involved in professional sports where sport-related injuries commonly occur and are associated with intense exercise which aims to improve physical fitness. The article attempts to determine incidence of sports injuries reported by Plus League volleyball players, as well as to identify their most common types and causes. The research project involved 90 Plus League volleyball players aged 18-37 with the average age of 25.11 (SD±5.378). A method of diagnostic survey was applied to collect empirical data by means of questionnaire developed by the authors (researchers). The results were statistically analysed and verified with the analysis of variance (ANOVA) and χ2 test at the significance level (or critical P-value) of P≤0.05. Over 87% of the respondents suffered from at least one sport-related injury. In total, 362 injuries occurred, on average 4.02 injuries per one volleyball player. The most common sports injuries involved ankle or talocrural joint (46 injuries), knee and lower leg muscles (30), interphalangeal articulations of fingers (30) as well as shoulder joint. More than half of the injuries (57%) occurred twice or three times. Volleyball players commonly sustain injuries through contact with an opposing player in competition. Sport-specific injuries may also occur due to exhaustion, lack of rest and undertreated injuries. The most common volleyball-related injuries are primarily talocrural joint, hand and shoulder injuries. Common types of injuries that can affect volleyball players include muscles, joints and ligaments injuries, sprains and strains as well as bruises. Most of these injuries are caused by exhaustion, contact with an opposing player during competition and fatigue. The incidence of sport-related injuries seems to be influenced by such factors as somatic

    Full Text Available Due to the increasing financial value of sport sponsorship, the selection of a sponsorship partner and the development of the sponsorship deal are crucial issues for sports businesses. This study examines the sponsorship selection and development process between football teams and their sponsors. This study is exploratory. Nine case studies were conducted involving three professional, premier league football clubs and six sponsoring organizations, two major sponsors of each club. Results were analysed with content analysis. Findings indicate that the most important selection criteria used from both sides are fit in corporate values of the two partners; revenue opportunities, and possible image enhancement from the deal. Also, results show that both sides use a structured process for developing the sponsorship deal that includes 3 major stages, information collection; preparation and presentation of proposal, and negotiations and contract sign. Also, we find that the sport property only sends proposals whereas the sponsor only receives; the actors in each stage of the process vary, and the extent of the process is affected by the duration and quality of the relationship between the two partners. The study involves nine cases and has limited generalizability. Future research should substantiate results in other settings and using quantitative methods. The findings of this study help sport managers to structure and formalize their sport sponsorship selection and development process. This way sport entities will be able to select the best possible partners for sponsorship and exploit to the fullest extent the money involved from both sides of the partnership (sponsors and sponsees. For the first time a structured process for development of new sponsorship deals is designed. This can help sport managers in managing sponsorships effectively and fast.

    Athletic pubalgia or sports hernia is a syndrome of chronic lower abdomen and groin pain that may occur in athletes and nonathletes. Because the differential diagnosis of chronic lower abdomen and groin pain is so broad, only a small number of patients with chronic lower abdomen and groin pain fulfill the diagnostic criteria of athletic pubalgia (sports hernia). The literature published to date regarding the cause, pathogenesis, diagnosis, and treatment of sports hernias is confusing. This article summarizes the current information and our present approach to this chronic lower abdomen and groin pain syndrome.

    1993-01-01

    Studies of the dietary practices of athletes report that nutritional supplements are commonly used. Supplementation practices vary between sports and individual athletes; however, there is evidence that at least some athletes use a large number of supplements concurrently, often in doses that are very high in comparison with normal dietary intakes. In exploring supplementation practices we propose a classification system separating the supplements into dietary supplements and nutritional erogogenic aids. The dietary supplement is characterised as a product which can be used to address physiological or nutritional issues arising in sport. It may provide a convenient or practical means of consuming special nutrient requirements for exercise, or it may be used to prevent/reverse nutritional deficiencies that commonly occur among athletes. The basis of the dietary supplement is an understanding of nutritional requirements and physiological effects of exercise. When the supplement is used to successfully meet a physiological/nutritional goal arising in sport it may be demonstrated to improve sports performance. While there is some interest in refining the composition or formulation of some dietary supplements, the real interest belongs to the use or application of the supplement; i.e. educating athletes to understand and achieve their nutritional needs in a specific sports situation. The sports drink (carbohydrate-electrolyte replacement drink) is a well known example of a dietary supplement. Scientific attitudes towards the sports drink have changed over the past 20 years. Initial caution that carbohydrate-electrolyte fluids compromise gastric emptying during exercise has now been shown to be unjustified. Numerous studies have shown that 5 to 10% solutions of glucose, glucose polymers (maltodextrins) and other simple sugars all have suitable gastric emptying characteristics for the delivery of fluid and moderate amounts of carbohydrate substrate.

    2017-02-01

    Promotions for online sports betting during televised sports broadcasts are regularly viewed by millions of Australians, raising concerns about their impacts on vulnerable groups including at-risk and problem gamblers. This study examined whether responses to these promotions varied with problem gambling severity amongst 455 Australian Internet sports bettors participating in an online survey. Results indicated that young male Internet sports bettors are especially vulnerable to gambling problems, particularly if they hold positive attitudes to gambling sponsors who embed promotions into sports broadcasts and to the promotional techniques they use and this heightens the risk that alluring messages contribute to excessive gambling. As problem gambling severity increased, so too did recognition that these promotions have impacted negatively on their sports betting behaviour. Because a plethora of sports betting brands and promotions are now heavily integrated into sports coverage, social marketing efforts are needed to offset their persuasive appeal and counter the positive attitudes towards them that appear linked to excessive gambling amongst Internet sports bettors.

    The aim of the study was to investigate the prevalence and the incidence of ocular complications in contact sport disciplines in a large population of professional and amateur athletes over a period of 3 years. We performed a retrospective review of 694 medical records from athletes examinated from 2008 to 2011. The following data were collected during the routine visit for agonistic sports eligibility: medical history, age, weight, years of sport practice, approximate number of matches, head and eyes injuries during and beyond of the match and a through ocular history. All athletes underwent a detailed ophthalmological evaluation. The follow-up of each athlete was carried out during the following routine visit for agonistic sports eligibility. Most common disorders observed were: peripheral retinal degeneration, blepharitis, conjunctival and corneal diseases with a prevalence of 7%, 4%, 7% and 4% respectively. It was observed a positive correlation between peripheral retinal degeneration and age in amateur male boxers. Moreover, we noticed an incidence of 6% of laser therapeutic treatments as a result of retinal holes or degenerations, during the follow-up. Contact sport disciplines did not result in higher prevalence of severe ocular lesion. Both conjuntival diseases and peripheral retinal degenerations represented the ophthalmologic disorders with the higher prevalence in our sample. In particular, peripheral retinal degeneration is remarkable because of the increased risk of retinal detachment. Dyschromatopsie, even if quite rare, should be considered when analysing the reception of shots, since gloves in most cases are either red or blue.

    A sport-specific measure of moral disengagement was developed in 2 studies. In Study 1, a 59-item questionnaire was developed and tested with 308 athletes from 5 team sports. A series of confirmatory factor analyses (CFA) testing different models suggested the model that best fitted the data had 6 first-order factors that could be represented by 1 second-order factor. Study 2 involved 305 athletes from the same 5 sports. CFA confirmed the 6-factor, second-order structure for the final 32-item measure. Results from Study 2 supported the construct validity of the scale, providing evidence for the factorial, concurrent, convergent, and discriminant validity. The Moral Disengagement in Sport Scale (MDSS) is proposed as a valid and reliable measure of moral disengagement for use in the sport context.

    Sports injuries healing has long been an important field in sports medicine. The stimulatory effects of Low intensity laser (LIL) irradiation have been investigated in several medical fields, such as cultured cell response, wound healing, hormonal or neural stimulation, pain relief and others. The aim of this study was to evaluate whether LIL irradiation can accelerate sports injuries healing. Some experimental and clinical studies have shown the laser stimulation effects on soft tissues and cartilage, however, controversy still exists regarding the role of LIL when used as a therapeutic device. Summarizing the data of cell studies and animal experiments and clinic trials by using the biological information model of photobiomodulation, we conclude that LIL irradiation is a valuable treatment for superficial and localized sports injuries and that the injuries healing effects of the therapy depend on the dosage of LIL irradiation.

    Every year > 600,000 sports and recreation related eye injuries occur, out of which roughly 13,500 of these result in permanent loss of sight. Up to 90% of these sports related eye injuries are preventable by using adequate eye protection equipment. Protective eyewear is made of polycarbonate, a highly impact-resistant plastic which is now easily available as prescription and non-prescription eyewear and all players should be encouraged to use them. The medical officers by educating their patients regarding the risks of eye injuries in various sports and the confirmed benefits of using protective equipment have the potential to prevent injury to over thousands of eyes every year. The medical fraternity can also play a very important role in educating the coaches, parents, and children and thus put an end to unnecessary blindness and vision loss from sports related ocular injuries, therefore ensuring a lifetime of healthy vision.

    This paper provides a brief summary and commentary on the growing literature on parenting in sport, with a particular emphasis on literature from the last 2-3 years. Following a brief introduction overviewing the topic area, we firstly focus on the influence of parental involvement on children. Specifically, we examine the range of factors that influence children's perceptions of parental involvement and the consequences of different behaviors. Next we discuss the factors influencing parental involvement, such as the challenges and stressors associated with parenting children in sport and the culture within different sports. Finally, our review focuses upon the strategies developed by parents to facilitate their involvement in their children's sport, as well as the few papers focused upon parent education and support. We conclude by examining the need for further research and examination of support strategies for parents. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    In spite of the wide range of injuries in adolescents during sports activities, there are only a few studies investigating the type and frequency of sport injuries in puberty. However, this information may help to prevent, diagnose and treat sports injuries among teens. 4468 injuries in adolescent patients were treated over a ten year period of time: 66,97% were boys and 32.88% girls. The most frequent sports injuries were football (31.13%) followed by handball (8.89%) and sports during school (8.77%). The lower extremity was involved in 68.71% of the cases. Knee problems were seen in 29.79% of the patients; 2.57% spine and 1.99% head injuries. Injuries consisted primarily of distortions (35.34%) and ligament tears (18.76%); 9,00% of all injuries were fractures. We found more skin wounds (6:1) and fractures (7:2) in male patients compared to females. The risk of ligament tears was highest during skiing. Three of four ski injuries led to knee problems. Spine injuries were observed most often during horse riding (1:6). Head injuries were seen in bicycle accidents (1:3). Head injuries were seen in male patients much more often then in female patients (21:1). Fractures were noted during football (1:9), skiing (1:9), inline (2:3), and during school sports (1:11). Many adolescents participate in various sports. Notwithstanding the methodological problems with epidemiological data, there is no doubt about the large number of athletes sustain musculoskeletal injuries, sometimes serious. In most instances, the accident does not happened during professional sports and training. Therefore, school teachers and low league trainer play an important role preventing further accidence based on knowledge of individual risk patterns of different sports. It is imperative to provide preventive medical check-ups, to monitor the sport-specific needs for each individual sports, to observe the training skills as well as physical fitness needed and to evaluation coaches education.

    Full Text Available This study contributes to the limited existing research on the participation patterns of Cypriots in leisure and sports. Leisure and sport are viewed collectively while adapting the notion put forth by The Council of Europe (2007 defining leisure sports as sports activities aimed at the preservation and improvement of physical condition, health and fun. The purpose of this paper is to examine the leisure sport participation patterns of Cypriots, specifically: (1 participation patterns in leisure sports, (2 reasons for participating in leisure sports, (3 cost and participation in leisure sport, (4 leisure sport spectatorship, and (5 vacationing and leisure sport experiences. Data was commissioned and collected by the Centre for Leisure, Tourism and Sports (University of Nicosia for the Cyprus Sport Organisation. A telephone-survey of 1000 Cypriots, men and women, aged 15+, from coast-to-coast in Cyprus using stratified random sampling was employed. The sample was weighted by gender, age, district and region of residence. The results indicate that: (1 almost half of the Cypriot population participates in leisure sports, (2 participation in leisure sports decreases with age, (3 participation in leisure sports tends to be driven by health benefits, (4 most Cypriots participate in leisure sport at no cost, (5 television is the most common means reported for spectatorship, and (6 some Cypriots plan their vacations around leisure sport experiences. The results indicate the relevant importance of the leisure sport culture in Cyprus while also reflecting on age and cost related factors that may influence participation in leisure sports.

    The purpose of this research was to observe the relationship among psychological variables and three important issues in sports competition: achieving success, long-term continuance and sustaining injuries. Three studies were carried out with three groups of athletes from the areas of judo, football and swimming, using the Questionnaire of Sports Performance-related Psychological Characteristics as the measuring instrument. The analyses carried out revealed significantly statistical associations between the perception of stress control and of self-confidence, and between achieving success, long-term continuance in competition sports and sustaining injuries. These results indicate the importance of psychological skills training to aid sports performance and prevent injuries, as well as the use of the above-mentioned questionnaire, which, with a limited number of items, measures a wide range of psychological variables in the specific context of sports.

    Sporting clubs play a key role in community-level physical activity. This study investigated participation trends in sport club membership. A survey of 50 State sports governing bodies in Victoria, Australia collected information on factors affecting membership trends. The records for four of these sports were analysed for the 6 years, 1998-2003. Three sports reported increases in total membership (average annual rates (AARs): 0.3, 1.9 and 12.4%), and one reported a decrease (AAR: -1.0%). There was a decrease in both the absolute number (AARs: -1.1%, -2.3%, and -3.5%) and the proportion (AARs: -0.5%, -0.7%, -1.7% and -2.3%) of adult members. The number of junior club members increased slightly over the 6-year period in two sports (AARs: 0.5% and 0.7%), increased substantially in one (AAR: 12.2%) and decreased in one (AAR: -6.7%). The number of members playing modified sports increased in two sports (AARs: 2.8% and 3.3%), increased substantially in one (AARs: 53.1%) and decreased in one (AAR: -16.3%). The introduction of modified sport for younger participants is relatively new, resulting in sports accessing a new market to maintain or increase their total membership. However, the influx of younger members was not matched by associated increases in adult members. This places increased pressure upon adult members to maintain the infrastructure to support younger members. The issues of decreased adult membership and increased junior membership need to be addressed in order to ensure that community sporting clubs can be sustained and fulfil their potential to act as a vehicle for public health initiatives.

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

    The purpose of this study was to investigate Paralympic coaches' perceptions of team cohesion. Seven head coaches of summer and winter Canadian Paralympic sport teams participated in the study. Four participants coached individual sports and 3 coached team sports. Data were collected using semistructured interviews and analyzed using thematic analysis. The results addressed the coaches' perceptions of cohesion in the Paralympic sport setting and strategies used to foster cohesion with their teams. Participants described using techniques and strategies for enhancing cohesion that were similar to those in nondisability sport, such as task-related activities, goal setting, and regularly communicating with their athletes. They also listed how cohesion was distinct to the Paralympic setting, such as the importance of interpersonal activities to build social cohesion. The implications of these results for coaching athletes with a disability are also presented.

  9. Tendinopathy in Sport

    Ackermann, Paul W.; Renström, Per

    2012-01-01

    Context: Tendinopathy is increasing in prevalence and accounts for a substantial part of all sports injuries and occupational disorders. Despite the magnitude of the disorder, high-quality scientific data on etiology and available treatments have been limited. Evidence Acquisition: The authors conducted a MEDLINE search on tendinopathy, or “tendonitis” or “tendinosis” or “epicondylitis” or “jumpers knee” from 1980 to 2011. The emphasis was placed on updates on epidemiology, etiology, and recent patient-oriented Level 1 literature. Results: Repetitive exposure in combination with recently discovered intrinsic factors, such as genetic variants of matrix proteins, and metabolic disorders is a risk factor for the development of tendinopathy. Recent findings demonstrate that tendinosis is characterized by a fibrotic, failed healing response associated with pathological vessel and sensory nerve ingrowth. This aberrant sensory nerve sprouting may partly explain increased pain signaling and partly, by release of neuronal mediators, contribute to the fibrotic alterations observed in tendinopathy. The initial nonoperative treatment should involve eccentric exercise, which should be the cornerstone (basis) of treatment of tendinopathy. Eccentric training combined with extracorporeal shockwave treatment has in some reports shown higher success rates compared to any therapies alone. Injection therapies (cortisone, sclerosing agents, blood products including platelet-rich plasma) may have short-term effects but have no proven long-term treatment effects or meta-analyses to support them. For epicondylitis, cortisone injections have demonstrated poorer long-time results than conservative physiotherapy. Today surgery is less indicated because of successful conservative therapies. New minioperative procedures that, via the endoscope, remove pathologic tissue or abnormal neoinnervation demonstrate promising results but need confirmation by Level 1 studies. Conclusions

    Full Text Available In Recent studies underline the fact that adolescents are, at many times, likely to experience serious communication problems with their families and close environments. So, the aim of this study is to determine positive impact of sport-related games, which are performed as extracurricular activities, on high school students’ communication skills. In the study, pre, & post-tests was utilized with the control group’s experimental patterns. Two participant groups were made up of totally 30 high school students, 15 of whom would be in the experimental group and the rest of whom were in the control group. The former group was given sport- related 20 applications for 10 weeks during which the latter group would not deal with any extracurricular activities. Meanwhile, before and after the applications, data was collected by means of “The Communication Skills Scale” which was developed by Korkut (1996 and then analysed through “two-way ANCOVA” test techniques. Results clarify that the considerable gap in scores of the students’ pre, & post-tests perception concerning their communication skills are clearly attributed to sport-related games and it was also established that scores of the students in the experimental group were meaningfully higher than ones in the control group. However, perception of communication skills in the both groups was not significantly different by sex of the students. Moreover, the common effect of sex and participation on sport- related games was not found statistically meaningful in terms of communication skills. Consequently, it could be said that sport-related games impact positively communication skills.

    Social media (e.g., Facebook and Twitter) use has increased considerably since its inception; however, research examining the relationship between social media use and sport has not progressed as rapidly. The purpose of the current study was to explore the prevalence rates of Facebook use among athletes around and during sport competitions and to investigate the relationships between sport anxiety and Facebook use. Two hundred and ninety-eight athletes of varying levels completed measures for sport anxiety and Facebook use, which included descriptive information about Facebook use prior to, during and following competitions. Results indicated that 31.9% of athletes had used Facebook during a competition and 68.1% had accessed Facebook within 2 h prior to competition. Time spent on Facebook prior to competition was significantly (and positively) correlated with the concentration disruption component of sport anxiety. Furthermore, regression analyses revealed that having push notifications enabled on an athletes' phone predicted 4.4% of the variability in sport anxiety. The percentage of athletes who accessed Facebook within 2 h of, or during, a competition is somewhat alarming considering the importance of psychological preparation in sport, which may compromise optimal psychological readiness and may lead to increased sport anxiety.

    Full Text Available Sport marketing involves marketing fundamentals applied in one industry, the sport business industry. The development of sport marketing fundamentals is therefore based on basic marketing principles. The practice and activities of sport marketing are also based on basic marketing activities, but are modified and adapted to the sport business industry. Therefore, sport marketing is based on its primary and parent discipline - marketing. Sport marketing is one of the most important functions of a sport business. This is because the sport marketing activities will define the business. The growth of the sport industry is phenomenal and shows no signs of slowing. Also, sport marketing is a process. A process is a continuous cycle. Therefore, marketing is a function that never ends. The sport marketing management model is an illustration of the elements and process of sport marketing. It should serve as a guide for managing the company’s marketing functions. The model illustrates the elements of marketing, the succession of elements and functions, the process of managing, and the interdependence of the elements This paper presents an overview of the model, sport marketing management, each element and the process.

    2003-02-01

    A two-months-old male infant with gastroenteritis had been given a sports drink (Aquarius) by the general practitioner as a treatment for dehydration and was referred because of ongoing vomiting and weight loss. The child recovered after reinstitution of normal bottle-feeding and administration of a regular oral rehydration solution (ORS). The sports drink was analysed and found to contain less salt than ORS. As a result, the salt:sugar ratio was not optimal. Sports drinks are therefore contraindicated in the treatment of dehydration in children.

    Full Text Available ResumenEsta investigación presenta un nuevo método para el estudio de la invarianza de escala que complementa otros métodos existentes, lo que contribuye a realizar un análisis ecléctico y multifocal de un problema importante en la investigación de marketing, y en particular en la investigación de servicios deportivos. Este método está basado en la utilización del cálculo integral y tiene una sencilla interpretación geométrica. Se describen y comparan varios procedimientos para testar la invarianza de escala, y se realiza un re-análisis de la investigación de Martínez y Martínez (2008b sobre la percepción de calidad del consumidor de servicios deportivos. Los resultados muestran cómo existen diferencias sobre las conclusiones originales de estos autores. De este modo, las escalas de siete opciones de respuesta sí son invariantes, mientras que la de cinco opciones no lo son. Finalmente, se discuten las bondades y las limitaciones del método integral, abogando por la triangulación estadística para dar robustez a los resultados empíricos.AbstractThis research introduces a new method to analyse scale invariance, which overcomes some shortcomings of other procedures. Under an eclectic perspective, this method must help to provide insights in the marketing research discipline, and specifically in the sports service management. The method is grounded on the use of definite integrals to compute the area between two functions. In addition, several procedures for testing scale invariance are depicted and compared. An empirical application is achieved by re-analysing the study of Martínez & Martínez (2008b on perceived quality in sports services. Results shows that misleading conclusions were derived from the original study of those authors. Finally, advantages and shortcomings of the new method are discussed.

    Context:  Certified athletic trainers (ATs) are responsible for integrating relevant professionals into the rehabilitation team to assist with the holistic care of injured athletes. Objective:  To explore National Collegiate Athletic Association Division I (DI) ATs' experience with sport psychology consultants (SPCs), willingness to encourage athletes to use SPCs for injury rehabilitation, and perceptions of the benefits of sport psychology services. Design:  Quantitative study. Setting:  A Web-based survey was administered to a national sample of DI ATs. Patients or Other Participants:  A total of 659 (341 men, 318 women) ATs completed the survey. Main Outcome Measure(s):  Athletic trainers' experience with SPCs, willingness to encourage athletes to seek sport psychology services, and perceptions of the benefits of those services in injury-rehabilitation settings were self-reported using a rating scale that ranged from 1 (never or not at all) to 5 (definitely or extremely). Results:  Logistic regression revealed that the availability of SPCs, previous encouragement to athletes to seek sport psychology services, and previous positive interactions with SPCs predicted the ATs' willingness to encourage athletes to use these services (P emotion, improving coping techniques, and building confidence (ie, confidence in returning to sport and building confidence). Chi-square analyses indicated that female ATs' ratings of perceived benefits were higher (P ≤ .001) than those of male ATs, and the ratings of ATs who were likely to encourage the use of SPCs were higher (P ≤ .001) than those who were unlikely to encourage SPC service use. Conclusions:  Athletic trainers in our study who had previous positive SPC experiences were most likely to use SPCs and their services during the injury-rehabilitation process. Possible implications are offered for how ATs interested in sport psychology services might call on SPCs to complement their work with injured

    Full Text Available The present paper analyses the causes that lead to violent behaviour in sport (from the social, economic, biological and psychological factors to the violent patterns promoted by mass media and it identifies the measures that could be adopted for preventing and fighting against this widespread phenomenon in today’s society. The phenomenon of violence in sport appeared subsequent to the “Sport Revolution”, which occurred in the 19th century, when sport became a mass and democratic phenomenon. Today sport is accessible to all society members for whom it has acquired cultural and economic importance; however, it is generally agreed that sport events are more or less frequently accompanied by violent behaviour on the part of most or some of its supporters. This scientific article enumerates the causes that trigger violent behaviour in society: from the inner ones (tension, fear, lack of success, incapacity to the social, biological, psychological and economic ones (lack of education, illnesses, trauma and poverty. Similarly, the present article analyses the influence of mass media upon human behaviour while taking into consideration two paradigms: there is a former paradigm, according to which mass media strongly influence human behaviour, by inculcating upon people violent reactions; there is a latter paradigm, according to which the influence of mass media on human behaviour is relatively insignificant for it is the individual that controls this influence. In this paper I have also analysed the risk factors that trigger violence and aggressiveness on stadiums, according to the inquiries made by the Ministry of Administration and Domestic Affairs. As solutions for violence prevention and deterrence, I have suggested: - the implementation of the objectives promoted by the Olympic Movement, which may contribute to the formation of a better and more peaceful world through the education of the youth in accordance with the principles and values of

    51 nonathletes, students (45 women) at a medium-sized southern university, were administered a survey containing three scales: an Interest in Sports Scale, a Belief in Sports Superstitions Scale, and Tobacyk and Milford's Paranormal Belief Scale (1983). Scores on the Interest in Sports Scale were significantly correlated with scores on the Belief in Sports Superstitions Scale, which measured adherence specifically to sports superstitions, but not with scores on the Paranormal Belief Scale, which measured a wide variety of irrational beliefs. Thus, participants with high interest in sports showed a tendency to subscribe to the type of irrational belief associated specifically with sports. Scores on the Belief in Sports Superstitions Scale were positively correlated with scores on the Paranormal Belief Scale.

    Full Text Available This study aims to investigate handgrip strengths of elite sportsmen who are involved in sport rock climbing. Study group was composed of 144 sportsmen from 22 countries who participated in Petzl Roc Trip sport rock climbing festival held in Turkey between 14 and 19 October 2014. Data were collected by using Takei Grip-D brand hand dynamometer. The data collected were analyzed and interpreted by statistical package programme (SPSS 16.0. Results show meaningful differences between sportsmen’s right handgrip strength and left handgrip strength. Sportsmen’s right handgrip strength was found to be higher. Results differed based on gender as well. Left and right handgrip strength of males was found to be higher to those of females. No significant relationships were detected based on nationality, age, history of climbing and period of experience in climbing. Relationships were observed between Turkish male and female climbers’ right and left handgrip strengths. As a result, it can be claimed that right hand is used more often in sport rock climbing compared to the left hand. It is also believed that fingers and technique are crucial in sport rock climbing. Practices to develop finger strength and techniques are suggested.

    Disability sport is growing around the world with momentum and is described as a “movement” (Bailey, 2008; DePauw & Gavron, 2005). While there are more similarities than differences with sport management for able-bodied athletes and those with disabilities, there are additional needs and considerations for persons with disabilities (DePauw & Gavron, 2005). The noticeable visibility of individuals with disabilities in society, including sport, raises concerns about the degree to which sport ma...

    Chronic groin pain is one the most complex conditions encountered in the field of sports medicine. Conservative treatment is long lasting and the result of treatment is often uncer- tain and symptom recurrences are common, which can be very frustrating for both the patient and the physician. The complex etiology and uncertainties during treatment of chronic groin pain is the reason why some authors call it the Bermuda Triangle of sports medicine. In our prospective, 7-year study, 114 athletes with chronic groin pain resistant to conservative therapy were treated surgically. In 109 athletes with sports hernia, we performed nerve neurolysis along with resection of the genital branch of the genitofemoral nerve and we also reinforced the posterior wall of inguinal canal using a modified Shouldice technique. In 26 athletes that had concomitant adductor tendinosis and in 5 athletes with isolated tendinosis we performed tenotomy. Eighty-one of 83 patients with isolated sports hernia returned to sports within a mean of 4.4 (range, 3-16) weeks. Thirty-one athletes with adductor tenotomy returned to sports activity within a mean of 11.8 (range, 10-15) weeks. If carefully diagnosed using detailed history taking, physical examination and correct imaging techniques, chronic groin pain can be treated very successfully and quickly, so it need not be a Bermuda Triangle of sports medicine.

    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.

    To determine the severity and long term sequelae of eye injuries caused by modern sports that could be responsible for significant ocular trauma in the future. Prospective observational study of 24 (25 eyes) athletes with sports related ocular injuries from health clubs, war games, adventure, radical and new types of soccer, presenting to an eye emergency department between 1992 and 2002 (10 years). Modern sports were responsible for 8.3% of the 288 total sports eye injuries reported. Squash (29.2%) was the most common cause, followed by paintball (20.8%) and motocross (16.6%). The most common diagnosis during the follow up period was retinal breaks (20%). 18 (75%) patients sustained a severe injury. The final visual acuity remained <20/100 in two paintball players. Ocular injuries resulting from modern sports are often severe. Adequate instruction of the participants in the games, proper use of eye protectors, and a routine complete ophthalmological examination after an eye trauma should be mandatory.

    The study analysed the experiences of participants on mass sport events, and explained the influence of such sport events on the lifestyle of runners. The study sample consisted of 664 participants of the 15th Ljubljana Marathon. The TRPS questionnaire was adjusted to establish the tourist roles. The role of sport tourists was assumed by 29.8% of all participants. Sport tourists who take various trips mainly for sport purposes (66.7%) participate more often in mass sport events at home and abroad and are more physically active in their leisure time. Moreover, 13 in-depth interviews were conducted with selected marathon participants. It was established that different travel behaviour and experiences from earlier sport events have influenced on their lifestyles.

    Sports psychologists play an important role in enhancing performance among athletes. In conjunction with team physicians, they can also shed light on psychological disorders common in athletes, such as mood and eating disorders, and overtraining syndrome. Sports psychologists can also lend their expertise to assist with injury prevention and recovery and compliance issues. Sports psychology has a role in helping to reverse the growing obesity epidemic among school-aged children. These professionals, working with coaches, can increase children's levels of physical activity. Cognitive-behavioral techniques could lead to enhanced enjoyment, increased participation, improved school performance, and a reduction in obesity.

    Full Text Available In sport marketing, the word promotion covers a range of interrelated activities. All of these activities are designed to attract attention, stimulate the interest and awareness of consumers, and of course, encourage them to purchase a sport product. Promotion is about communicating with and educating consumers. The purpose of a sport promotional strategy is to build brand loyalty and product credibility, develop image, and position the brand. A promotional strategy is similar to a marketing strategy, but the promotional strategy seeks short-term objectives, both direct and indirect. Promotional objectives usually include increased sales, stimulate impulse buying, raise customer traffic, and present and reinforce image. It also provides information about products and services, publicizes new stores or websites, and creates and enhances customer satisfaction.

For Chinese, the Olympics is about national pride and cultural legacy. The Chinese government hopes to make this event a morale booster for the development of the whole country. And for the world, the Olympics is not just a global sporting event, but also an important platform for promoting world harmony and communication between cultures. As editor of Contemporary International Relations, I am mindful of the connection between sport and international relations. Sport today plays a highly significant role in the world, and the impact of this global phenomenon on international relations is often underestimated.

    Introduction Sports clubs form a potential setting for health promotion, but the research is limited. The aim of the Health Promoting Sports Club (HPSC) study was to elucidate the current health promotion activities of youth sports clubs and coaches, and to investigate the health behaviours and health status of youth participating in sports clubs compared to non-participants. Methods and analysis The study design employs cross-sectional multilevel and multimethod research with aspirations to a prospective cohort study in the next phase. The setting-based variables at sports clubs and coaching levels, and health behaviour variables at the individual level, are investigated using surveys; and total levels of physical activity are assessed using objective accelerometer measurements. Health status variables will be measured by preparticipation screening. The health promotion activity of sports clubs (n=154) is evaluated by club officials (n=313) and coaches (n=281). Coaches and young athletes aged 14–16 (n=759) years evaluate the coaches’ health promotion activity. The survey of the adolescents’ health behaviours consist of two data sets—the first is on their health behaviours and the second is on musculoskeletal complaints and injuries. Data are collected via sports clubs (759 participants) and schools 1650 (665 participants and 983 non-participants). 591 (418 athletes and 173 non-athletes) youth, have already participated in preparticipation screening. Screening consists of detailed personal medical history, electrocardiography, flow-volume spirometry, basic laboratory analyses and health status screening, including posture, muscle balance, and static and dynamic postural control tests, conducted by sports and exercise medicine specialists. Ethics and dissemination The HPSC study is carried out conforming with the declaration of Helsinki. Ethical approval was received from the Ethics Committee of Health Care District of Central Finland.

Stress fractures are recorded and described up to the lower limbs. Research has been confirmed that the bones of lower leg are mostly made in injury, and with the el- derly and with the population of children and young adolescents. Occur in many sports, something to them is greater when the frequency of running and often are present in the female population. According to the results of numerous investigations, mistakes in the training are the most common cause of the emergence of stress fracture.

    Ball sports have been part of human history for thousands of years [1]. Nowadays, 13 of them are part of the Olympic games (badminton, basketball, beach volley, football/soccer, golf, handball, hockey, rugby, table tennis, tennis, volleyball, water polo, ice hockey). All these games differ by launcher (hand, club, racket, bat), ball (size, shape and mass), pitch size and number of players. These differences induce different ball velocities. Apart from the velocities and the way to maximize them, we discuss in this article the ball trajectories and their impact on the size of sports fields.

    Maxillofacial injuries occur in contact and noncontact sports. Despite advancements in protective equipment and rule changes, there is still an unacceptably high rate of maxillofacial injuries. These injuries are clinically challenging. The significant morbidity, deformity, and disability associated with these injuries can be avoided by their prompt diagnosis and appropriate management. It is important for the sports medicine professional to be competent in the correct diagnosis and management of maxillofacial injuries. This article reviews some of the major maxillofacial injuries, along with their emergent examinations and treatments.

    The automatic analyser is based on a photoelectric aerosol sensor, with continuous sampling and an on-line detection system. Traditional sampling monitoring systems consist of collecting airborne particulate on filters; the sample is then extracted, purified and analysed. It is possible to identify each compound and to determine its relative abundance in the total particulate matter, on the other hand, this method requires great complexity of analysis. Continuous monitoring systems allow getting quicker results to compare with threshold levels. It is also possible to obtain an easier correlation with factors such as traffic flows or meteorological conditions. However, such systems cannot quantify single compounds, and data are expressed as total PAH. The comparison between the results shows a satisfactory linearity between the data obtained with the two methods. The difference of about one order of magnitude between the data obtained with photoelectric aerosol sensor (PAS) system and the sum of the concentrations of selected PAHs determined with off-line methods can be explained with the different selectivity of the two methods employed. This work has been developed in Aosta, the administrative centre of the Aosta Valley district.

    Full Text Available Starting from the need to tackle in a sustainable way the new economic and social requirements particularly induced by the recent financial crisis, corporate social responsibility (CSR is one envisaged solution at community and organizational level, because of its win-win strategic potential. More than that, acknowledging the economic impact of strongly supporting social domains like education and sport, the European Union (EU has designed new measures for developing the human potential during 2014-2020 period. Following these two rationales, the main research objective is to emphasize the relationship between CSR and corporate support for educational and sport projects of top performing companies in Romania, Bulgaria and Croatia in the post-crisis period. Four main issues are investigated in detail regarding the corporate support for education and sport areas through CSR initiatives, namely existence of corporate involvement, forms of commitment, reasons for engagement, and main beneficiaries of implication. The research methodology focuses on empirical and analytical perspectives, while the results show new facets and implications of CSR initiatives in education and sport domains, but also a set of similarities and differences between the analysed EU countries. Economic and social impacts are also examined, as well as future research directions.

    2014-03-01

    As one of the purposes of anterior cruciate ligament reconstruction (ACLR) is to return athletes to their preinjury activity level, it is critical to understand variables influencing return to sport. Associations between return to sport and variables representing knee impairment, function and psychological status have not been well studied in athletes following ACLR. The purpose of this review was to summarise the literature reporting on variables proposed to be associated with return to sport following ACLR. Systematic review. Medline, EMBASE, CINAHL and Cochrane databases were searched for articles published before November 2012. Articles included in this review met these criteria: (1) included patients with primary ACLR, (2) reported at least one knee impairment, function or psychological measure, (3) reported a return to sport measure and (4) analysed the relationship between the measure and return to sport. Weak evidence existed in 16 articles suggesting variables associated with return to sport included higher quadriceps strength, less effusion, less pain, greater tibial rotation, higher Marx Activity score, higher athletic confidence, higher preoperative knee self-efficacy, lower kinesiophobia and higher preoperative self-motivation. Weak evidence supports an association between knee impairment, functional and psychological variables and return to sport. Current return to sport guidelines should be updated to reflect all variables associated with return to sport. Utilising evidence-based return to sport guidelines following ACLR may ensure that athletes are physically and psychologically capable of sports participation, which may reduce reinjury rates and the need for subsequent surgery.

  4. Sports participation of children with or without developmental delay: prediction from child and family factors.

    2015-02-01

    Sports participation is beneficial to health and socioemotional adjustment in youth across development. While there is some evidence indicating lower sports participation for children with developmental delays (DD) as compared with their typically developing (TD) peers, little is known as to the predictors of this differential participation. Given the increased risk of physical and mental health difficulties for children with DD, understanding more about this disparity is important. We examined sports participation in elementary school-aged children with or without DD and examined child and family predictors of three indices of sports participation: number of sports and highest relational sport at ages 6 and 8, and consistent sports from 6 to 8. Children with TD were significantly higher on all three indicators. Mother and child factors related significantly to sports participation indices. The number of sports related positively to mother education and positive perceptions and negatively to mother employment. Relational sports were higher in boys, children with higher social skills, and lower behavior problems. In regression analyses at child age 8 that included these other variables, delay status (DD or TD) did not have a significant effect. Perspectives on varying influences on sports participation and implications for intervention are discussed.

    Motivation is widely-researched, in both sport psychology and other fields. As rigorous measurement is essential to understanding this latent construct, a critical appraisal of measurement instruments is needed. Thus, the purpose of this review was to evaluate the six most highly cited motivation measures in sport. Peer-reviewed articles published prior to August 2016 were searched to identify the six most highly cited motivation questionnaires in sport: Sport Motivation Scale (SMS), Intrinsic Motivation Inventory (IMI), Situational Motivational Scale (SIMS), Perceptions of Success Questionnaire (POSQ), Behavioural Regulation in Sport Questionnaire (BRSQ), and Task and Ego Orientation in Sport Questionnaire (TEOSQ). The questionnaires were then evaluated and discussed in four sections: Development, Reliability, Correlates, and Summary. Bibliometric data were also calculated (average weighted impact factor) and assessed (e.g., citations per year) to evaluate the impact of the use of each questionnaire. Despite some variance in their psychometric properties, conceptualization, structure, and utility, the six questionnaires are psychometrically strong instruments for quantifying motivation that are widely supported in the literature. Bibliometric analyses suggested that the IMI ranks first and the SMS ranks sixth according to the average weighted impact factors of their original publications. Consideration of each questionnaire's psychometric strengths/limitations, and conceptualization of motivation in the context of specific research questions should guide researchers in selecting the most appropriate instrument to measure motivation in sport. The average weighted impact factor of each questionnaire is a useful value to consider as well. With these points in mind, recommendations are provided.

    Sports genetics can take advantage of lessons learned from human disease genetics. By righting past mistakes and increasing scientific rigor, we can magnify the breadth and depth of knowledge in the field. We present an outline of challenges facing sports genetics in the light of experiences from medical research. Sports performance is complex, resulting from a combination of a wide variety of different traits and attributes. Improving sports genetics will foremost require analyses based on detailed phenotyping. To find widely valid, reproducible common variants associated with athletic phenotypes, study sample sizes must be dramatically increased. One paradox is that in order to confirm relevance, replications in specific populations must be undertaken. Family studies of athletes may facilitate the discovery of rare variants with large effects on athletic phenotypes. The complexity of the human genome, combined with the complexity of athletic phenotypes, will require additional metadata and biological validation to identify a comprehensive set of genes involved. Analysis of personal genetic and multiomic profiles contribute to our conceptualization of precision medicine; the same will be the case in precision sports science. In the refinement of sports genetics it is essential to evaluate similarities and differences between sexes and among ethnicities. Sports genetics to date have been hampered by small sample sizes and biased methodology, which can lead to erroneous associations and overestimation of effect sizes. Consequently, currently available genetic tests based on these inherently limited data cannot predict athletic performance with any accuracy.

    Given the uncertainty of outcome in sport, predicting the outcome of sporting contests is a major topic in sport sciences. This study examines the accuracy of expert predictions in the German Bundesliga and compares their predictions to those of sports economists. Prior to the start of each season, a set of distinguished experts (head coaches and players) express their subjective evaluations of the teams in school grades. While experts may be driven by irrational sentiments and may therefore systematically over- or underestimate specific teams, sports economists use observable characteristics to predict season outcomes. The latter typically use team wage bills given the positive pay-performance relationship as well as other factors (average team age, tenure, appearances on national team, and attendance). Using data from 15 consecutive Bundesliga seasons, the predictive accuracy of expert evaluations and sports economists is analysed. The results of separate estimations show that relative grade and relative wage bill significantly affect relative points, while age, tenure, appearances, and attendance are insignificant. In a joint model, relative grade and relative wage bill are still statistically significant, suggesting that the two types of predictions are complements rather than substitutes. Consequently, football experts and sports economists seem to rely on completely different sources of information when making their predictions.

    Full Text Available Objectives: To learn about the coach-athlete interactions and understand the practice of leadership, motivational atmosphere generation and communication between players and sport leaders. Methodology: Mixed cohort methodology. A correlation of quantitative variables was performed and the experience and sense of sporting context were analysed with a qualitative approach. The following instruments were applied to 31 college athletes: Perceived Motivational atmosphere in Sport (PMASQ-2 Sport atmosphere (SA and ego orientation and Task in Sport. To obtain further information, semi-structured interviews were carried out to 6 athletes and 2 university coaches. Results: the sportsperson’s feeling of confidence in his/her coach is a result of his/her feeling understood and accepted by the coach. He/She generates a motivational atmosphere oriented towards ego is related to athletes with ego-goal orientations. Coaches use two opposing styles of leadership: democratic leadership (training and autocratic leadership (competitions Conclusions: When sportspeople trust the person who coaches them, they experience more satisfaction in sport. Moreover, when the coach promotes social comparison, this contributes to create rivalry among teammates and to base their performance in sport results.

    Previous research examining labour migration in sport focused on athletes in professional team sports. The purpose of this study is to analyse the factors influencing the migration probability of elite sport coaches in Germany (i.e. national coaches, state coaches, and coaches at Olympic training bases). From a theoretical perspective, labour migration of athletes is affected by economic, social, political, competitive, geographic and cultural factors. This study examines whether these factors can be applied to coaches. Primary data were collected using an online survey of elite sport coaches in Germany. Applying a conjoint design, respondents were presented with 10 migration scenarios leading to a sample size of n = 1860 for the empirical analysis. In the scenarios, the coaching position openings abroad differed in terms of income level, contract length, weekly workload, responsibility for personnel, reputation of coaching job, career perspectives, sporting performance of athletes, distance from Germany, and predominant job language. Coaches were asked for their migration probability contingent on the specific scenario. On average, migration probability was 24.2%. The results of regression analysis showed that higher income, contracts of longer duration, responsibility for personnel and speaking the respective language significantly increased the migration probability, while distances of nine flight hours and more, lower reputation and career perspectives reduced it. The findings have implications for policy-makers: they indicate in what areas the situation of coaches needs improvement to increase the likelihood of retaining elite sport coaches in the German sport system.

    Organizational stressors are particularly prevalent across sport performers' experiences and can influence their performance, health, and well-being. Research has been conducted to identify which organizational stressors are encountered by sport performers, but little is known about how these experiences vary from athlete to athlete. The purpose of this study was to examine if the frequency, intensity, and duration of the organizational stressors that sport performers encounter vary as a function of gender, sport type, and performance level. Participants (n = 1277) completed the Organizational Stressor Indicator for Sport Performers (OSI-SP; Arnold et al., 2013), and the resultant data were analyzed using multivariate analyses of covariance. The findings show that demographic differences are apparent in the dimensions of the goals and development, logistics and operations, team and culture, coaching, and selection organizational stressors that sport performers encounter. More specifically, significant differences were found between males and females, between team and individual-based performers, and between performers competing at national or international, regional or university, and county or club levels. These findings have important implications for theory and research on organizational stress, and for the development of stress management interventions with sport performers.

    We sought to evaluate frequency, characteristics, and outcomes of sudden cardiac arrest (SCA) during sports activities according to the location of occurrence (in sports facilities vs those occurring outside of sports facilities). This is an observational 5-year prospective national French survey of subjects 10 to 75 years old presenting with SCA during sports (2005-2010), in 60 French administrative regions (covering a population of 35 million people). Of the 820 SCA during sports, 426 SCAs (52%) occurred in sports facilities. Overall, a substantially higher survival rate at hospital discharge was observed among SCA in sports facilities (22.8%, 95% CI 18.8-26.8) compared to those occurring outside (8.0%, 95% CI 5.3-10.7) (P facilities were younger (42.1 vs 51.3 years, P facilities (9.3 vs 13.6, P=0.03), and the proportion of initially shockable rhythm was higher (58.8% vs 33.1%, P facilities was mainly explained by concomitant circumstances of occurrence (adjusted odds ratio 1.48, 95% CI 0.88-2.49, P = .134). Sports-related SCA is not a homogeneous entity. The 3-fold higher survival rate reported among sports-related SCA is mainly due to cases that occur in sports facilities, whereas SCA during sports occurring outside of sports facilities has the usual very low rate of survival.

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.

  14. Phospholipids and sports performance

    2007-07-01

    Full Text Available Abstract Phospholipids are essential components of all biological membranes. Phosphatidylcholine (PC and Phosphatidylserine (PS are Phosphatidyl-phospholipids that are required for normal cellular structure and function. The participation in physical activity often challenges a variety of physiological systems; consequently, the ability to maintain normal cellular function during activity can determine sporting performance. The participation in prolonged intense exercise has been shown to reduce circulatory choline concentrations in some individuals. As choline is a pre-cursor to the neurotransmitter Acetylcholine, this finding has encouraged researchers to investigate the hypothesis that supplementation with PC (or choline salts could enhance sporting performance. Although the available data that evaluates the effects of PC supplementation on performance are equivocal, acute oral supplementation with PC (~0.2 g PC per kg body mass has been demonstrated to improve performance in a variety of sporting activities where exercise has depleted circulatory choline concentrations. Short term oral supplementation with soy-derived PS (S-PS has been reported to attenuate circulating cortisol concentrations, improve perceived well-being, and reduce perceived muscle soreness after exercise. More recently, short term oral supplementation (750 mg per day of S-PS for 10 days has been demonstrated to improve exercise capacity during high intensity cycling and tended to increase performance during intermittent running. Although more research is warranted to determine minimum dietary Phospholipid requirements for optimal sporting performance, these findings suggest that some participants might benefit from dietary interventions that increase the intakes of PC and PS.

    Davis, Gavin A; Castellani, Rudolph J; McCrory, Paul

    2015-06-01

    The recent interest in concussion in sport has resulted in significant media focus about chronic traumatic encephalopathy (CTE), although a direct causative link(s) between concussion and CTE is not established. Typically, sport-related CTE occurs in a retired athlete with or without a history of concussion(s) who presents with a constellation of cognitive, mood, and/or behavioral symptoms and who has postmortem findings of tau deposition within the brain. There are many confounding variables, however, that can account for brain tau deposition, including genetic mutations, drugs, normal aging, environmental factors, postmortem brain processing, and toxins. To understand the roles of such factors in neurodegenerative diseases that may occur in athletes, this article reviews some neurodegenerative diseases that may present with similar findings in nonathletes. The article also reviews pathological changes identified with normal aging, and reviews the pathological findings of CTE in light of all these factors. While many of these athletes have a history of exposure to head impacts as a part of contact sport, there is insufficient evidence to establish causation between sports concussion and CTE. It is likely that many of the cases with neuropathological findings represent the normal aging process, the effects of opiate abuse, or a variant of frontotemporal lobar degeneration. Whether particular genetic causes may place athletes at greater risk of neurodegenerative disease is yet to be determined.

    2013-04-01

    Due to pressures within the sport environment, such as from coaches, teammates, uniforms and judges, female athletes may develop unhealthy eating practices to lose weight or change their body size/shape to become more competitive and meet societal and sport-related physique ideals. However, up until the development of the Weight Pressures in Sport for Females (WPS-F; Reel, SooHoo, Petrie, Greenleaf, & Carter, 2010) there was no way to quantify sport-specific weight pressures with female athletes. In this study, the psychometric properties of the scale were further examined using a sample of 414 female collegiate athletes. Sample 1 [n=207; M=19.27 years; SD=1.16] and Sample 2 [n=207; M=19.19 years; SD=1.66] participants were of a similar age and were used for exploratory and confirmatory analyses respectively. A two factor structure was confirmed and it was established that the scale was unique from general sociocultural pressures that all women experience, predicting female athletes' internalization, body dissatisfaction, dietary intent, and bulimic symptomatology. Specifically, the following factors, Coach and Sport Pressures about Weight (Factor 1) and Pressures Regarding Appearance and Performance (Factor 2), were found to have strong internal consistency and the emerging reliable and valid WPS-F has practical implications for screening and identifying weight-related sport pressures within female athletes. WPS-F can also serve to educate sport professionals about environmental pressures so that disordered eating and body image disturbances can be prevented.

    Despite the growing interest in Paralympic sport, the evidence base for supporting elite wheelchair sport performance remains in its infancy when compared with able-bodied (AB) sport. Subsequently, current practice is often based on theory adapted from AB guidelines, with a heavy reliance on anecdotal evidence and practitioner experience. Many principles in training prescription and performance monitoring with wheelchair athletes are directly transferable from AB practice, including the periodization and tapering of athlete loads around competition, yet considerations for the physiological consequences of an athlete's impairment and the interface between athlete and equipment are vital when targeting interventions to optimize in-competition performance. Researchers and practitioners are faced with the challenge of identifying and implementing reliable protocols that detect small but meaningful changes in impairment-specific physical capacities and on-court performance. Technologies to profile both linear and rotational on-court performance are an essential component of sport-science support to understand sport-specific movement profiles and prescribe training intensities. In addition, an individualized approach to the prescription of athlete training and optimization of the "wheelchair-user interface" is required, accounting for an athlete's anthropometrics, sports classification, and positional role on court. In addition to enhancing physical capacities, interventions must focus on the integration of the athlete and his or her equipment, as well as techniques for limiting environmental influence on performance. Taken together, the optimization of wheelchair sport performance requires a multidisciplinary approach based on the individual requirements of each athlete.

    Two in situ plane-strain deformation experiments on norcamphor and natural ice using synchronous recording of crystal c-axis orientations have been performed with an automated fabric analyser and a newly developed sample press and deformation stage. Without interrupting the deformation experiment, c-axis orientations are determined for each pixel in a 5 × 5 mm sample area at a spatial resolution of 5 μm/pixel. In the case of norcamphor, changes in microstructures and associated crystallographic information, at a strain rate of ∼2 × 10(-5) s(-1), were recorded for the first time during a complete in situ deformation-cycle experiment that consisted of an annealing, deformation and post-deformation annealing path. In the case of natural ice, slower external strain rates (∼1 × 10(-6) s(-1)) enabled the investigation of small changes in the polycrystal aggregate's crystallography and microstructure for small amounts of strain. The technical setup and first results from the experiments are presented. © 2010 The Authors Journal of Microscopy © 2010 Royal Microscopical Society.

  4. Sanctions for doping in sport

    Full Text Available Top-level sport imposes new and more demanding physical and psychological pressures, and the desire for competing, winning and selfassertion leads athletes into temptation to use prohibited substances in order to achieve the best possible results. Regardless of the fact that the adverse consequences of prohibited substances are well-known, prestige and the need to dominate sports arenas have led to their use in sports. Doping is one of the biggest issues in sport today, and the fight against it is a strategic objective on both global and national levels. World Anti-Doping Agency, the International Olympic Committee, international sports federations, national anti-doping agencies, national sports federations, as well as governments and their repressive apparatuses are all involved in the fight against doping in sport. This paper points to a different etymology and phenomenology of doping, the beginnings of doping in sport, sports doping scandals as well as the most important international instruments regulating this issue. Also, there is a special reference in this paper to the criminal and misdemeanor sanctions for doping in sport. In Serbia doping in sport is prohibited by the Law on Prevention of Doping in Sports which came into force in 2005 and which prescribes the measures and activities aimed at prevention of doping in sport. In this context, the law provides for the following three criminal offenses: use of doping substances, facilitating the use of doping substances, and unauthorized production and putting on traffic of doping substances. In addition, aiming at curbing the abuse of doping this law also provides for two violations. More frequent and repetitive doping scandals indicate that doping despite long-standing sanctions is still present in sports, which suggests that sanctions alone have not given satisfactory results so far.

    2012-01-01

    Full Text Available Objective. There are no reports comparing the protocols provided by rigid marker set (RMS and point cluster technique (PCT, which are similar in terms of estimating anatomical landmarks based on markers attached to a segment. The purpose of this study was to clarify the correlation of the two different protocols, which are protocols for knee motion in gait, and identify whether measurement errors arose at particular periods during the stance phase. Methods. The study subjects were 10 healthy adults. All estimated anatomical landmarks were which their positions, calculated by each protocol of the PCT and RMS, were compared using Pearson’s product correlation coefficients. To examine the reliability of the angle changes of the knee joint measured by RMS and the PCT, the coefficient of multiple correlations (CMCs was used. Results. Although the estimates of the anatomical landmarks showed high correlations of >0.90 (<0.01 for the Y- and Z-coordinates, the correlations were low for the X-coordinates at all anatomical landmarks. The CMC was 0.94 for flexion/extension, 0.74 for abduction/adduction, and 0.71 for external/internal rotation. Conclusion. Flexion/extension and abduction/adduction of the knee by two different protocols had comparatively little error and good reliability after 30% of the stance phase.

    The ratio of the lengths of the second to fourth digits of the hand (2D:4D) is a sexually dimorphic trait that has been proposed as a measure of prenatal testosterone exposure and a putative correlate of a variety of later behavioral and physiological outcomes including personality, fitness and sexual orientation. We present analyses of 2D:4D ratios collected from twins (1413 individuals) and their nontwin siblings (328 individuals) from 757 families. In this sample 2D:4D was measured from photocopies using digital calipers, and for a subset of participants, computer-aided measurement. Multivariate modeling of the left- and right-hand measurements revealed significant genetic and environmental covariation between hands. The two methods yielded very similar results, and the majority of variance was explained by factors shared by both measurement methods. Neither common environmental nor dominant genetic effects were found, and the covariation between siblings could be accounted for by additive genetic effects accounting for 80% and 71% of the variance for the left and right hands, respectively. There was no evidence of sex differences in the total variance, nor in the magnitude or source of genetic and environmental influences, suggesting that X-linked effects (such as the previously identified association with the Androgen receptor) are likely to be small. However, there were also nonshared environmental effects specific to each hand, which, in addition to measurement error, may in part explain why some studies within in the literature find effects for the 2D:4D ratio of one hand but not the other.

    Full Text Available The atmospheric organic aerosol composition is characterized by a great diversity of functional groups and chemical species challenging simple classification schemes. Traditional off-line chemical methods identified chemical classes based on the retention behavior on chromatographic columns and absorbing beds. Such approach led to the isolation of complex mixtures of compounds such as the humic-like substances (HULIS. More recently, on-line aerosol mass spectrometry (AMS was employed to identify chemical classes by extracting fragmentation patterns from experimental data series using statistical methods (factor analysis, providing simplified schemes for oxygenated organic aerosols (OOAs classification on the basis of the distribution of oxygen-containing functionalities. The analysis of numerous AMS datasets suggested the occurrence of very oxidized OOAs which were postulated to correspond to the HULIS. However, only a few efforts were made to test the correspondence of the AMS classes of OOAs with the traditional classification from the off-line methods.

  11. Indigenous Participation in Australian Sport: The Perils of the ‘Panacea’ Proposition

    Directory of Open Access Journals (Sweden)

    John Robert Evans

    2015-04-01

    Full Text Available The argument that participation in sport among disadvantaged populations can produce positive outcomes in wide range of areas has been a consistent theme in academic literature. It is argued that sport participation can promote women’s empowerment, sexuality, lifestyle, peacemaking, youth development, poverty reduction and conflict resolution. Similarly, in Australia, participation in sport among Indigenous Australians has been proffered as a ‘panacea’ for many Indigenous problems; from promoting better health and education outcomes, to encouraging community building, good citizenship and entrepreneurship. Parallel to this has been a focus on documenting and analysing sport participation among Indigenous Australians in elite sport which often concludes that Indigenous Australians have an innate and ‘natural ability’ in sports. These two assumptions, first, that sport participation can help realise a wide range of positive social outcomes; and second, that Indigenous Australians are natural athletes, have driven significant public investment in numerous sport focused programs. This paper questions these assumptions and outlines some of the challenges inherent with an emphasis on sport as a solution to Indigenous disadvantage. We highlight how participation in sport has often been tied to ambitious, ill-defined and, in terms of evaluation, often elusive social outcome goals. Second, we also argue that there is limited research to indicate that participation in either elite or grassroots level sport has led to any discernible social progress in addressing inequality. We contrast historical Indigenous participation in a range of sporting codes to demonstrate the influence of factors beyond the ‘natural ability’ and ‘born to play’ propositions. Finally, we outline six ‘perils’ associated with viewing sport as a panacea; including how privileging sport can not only perpetuate disadvantage by reinforcing stereotypes and also

    The contribution of sport to overall health-enhancing leisure-time physical activity (HELPA) in adults is not well understood. The aim was to examine this in a national sample of Australians aged 15+ years, and to extend this examination to other ostensibly sport-associated activities. The 2010 Exercise, Recreation and Sport Survey (ERASS) was conducted by telephone interview in four quarterly waves. Data from this survey were analysed to categorise leisure-time physical activity (LTPA) as HELPA or non-HELPA, and to categorise HELPA activities and sessions of HELPA activity by setting and frequency. The contribution of sport to HELPA was estimated, both directly through activities and settings classified as sport per se, and indirectly through other fitness activities ostensibly related to preparation for sport and enhancement of sport performance. Of 21,602 respondents, 82 % reported some LTPA in the 12 months prior to the survey. In aggregate, respondents reported 37,020 activity types in the previous 12 months, of which 94 % were HELPA. Of HELPA activities, 71 % were non-organised, 11 % were organised but not sport club-based, and 18 % were sport club-based. Of all sport activities, 52 % were HELPA. Of sport HELPA, 33 % was sport club-based and 78 % was undertaken ≥12 times/year. Sport club members were significantly more likely to have participated in running, but significantly less likely to have participated in walking or aerobics/fitness training, than non-club members. Club sport participation contributes considerably to LTPA at health enhancing levels. Health promotion policies, and more specifically physical activity policies, should emphasize the role of sport in enhancing health. Sport policy should recognise the health-promoting role of community-based sport in addition to the current predominant focus on elite pathways.
