    Opis:
    Sports Medicine (SM) is a new specialty in India which has been often projected, dealing only with treating musculoskeletal (MSK) sports injuries. With adequate training in medical and clinical physiology, SM physicians have an important role to play as an essential part of the multidisciplinary and multispecialty team in the fight against the rise of physical inactivity, sedentary lifestyle and non-communicable diseases. Dope-free sports performance enhancement is another important aspect, which needs beyond the MSK centric approach of sports medicine. There is need for awareness and overall development of this unique specialty, with contribution from government side and non-government organizations.

    Opis:
    Learned helplessness is often studied as a consequence of repetitive failure in a performance domain and is usually associated with the experience of uncontrollability over future outcomes. The premise of this review article is first to establish initial support towards the notion of learned helplessness seen in the context of sports performance. Furthermore, the role of performance anxiety and maladaptive perfectionism will be introduced to strengthen the idea that thinking traits impact motor performance especially when these traits moderate the effects of consecutive failure experience. Finally the paper will focus on a typical profile of an athlete who would be susceptible to choking under pressure as an outcome of perceived uncontrollability and performance anxiety. Burnout and potential interventions will be discussed later.

    Opis:
    The objective of this study was to evaluate the reliability and validity of two alternative systems used for jumping performance measurement. Methods: Two groups of subjects were tested. The first group consisted of 15 male adults (21.3 ± 1.7 years ) and the second group consisted of 16 female volleyball players (17.2 ± 0.9 years). We used three different systems of data collection in the study. Two of the used systems are based on optoelectric components. The Optojump Next system is referred to as the optoelectric system, and BTS Smart-E is refered to as the video system. Concurrent validity of these systems was verified with the use of “gold standard” which is force platform. All systems were used to estimate the height of vertical jumps. Results: Both optoelectric systems occurred to be highly reliable with the ICCs=0.98 for Optojump and 0.9 for BTS Smart. Their concurrent validity with the force platform data was also very high r=0.99 and r=0.97 respectively. Conclusions: Comparison of these two systems shows distinct differences between them where Optojump system is more suitable for quick and reliable sports testing, when BTS-Smart for research and clinical testing.

    Opis:
    The aim of this study was to compare the player positions, situations, techniques, and efficacy in defence between practice and competition for a women’s professional volleyball team. The sample was a Spanish professional women’s volleyball team. The defence actions carried out in three sessions of the competitive season and two in-season matches were studied (794 rallies in practice and 166 rallies in competition). The variables studied were: actions done, defence zone, player role, type of attack, court defence technique, game phase, situations, level of execution of the defence team system, block efficacy, defence efficacy, and result of the rally for the analysed team. Descriptive and inferential analyses of the data were done (Mann-Whitney U, and Chi-Square Test and likelihood ratio). Differences in defence systems and efficacies were found between practice and competition. A higher collective efficacy was found in competition, and higher levels of individual block and defence efficacies were found in practice. The results show the need to reconsider the way match analysis is done. Consideration should not only be given to the actions done with the ball when analysing players’ performance.

    Opis:
    Proper diet is a well-established factor influencing the effectiveness of training. to assess the knowledge of young sportspeople from Wrocław about sport nutritional strategies an online survey was distributed to Wrocław sport schools and clubs. the respondents were asked to answer questions regarding their sport activity, diet and the knowledge of nutrition strategies. the answers were then compared with the recommended strategies of international Society of Sports Nutrition (iSSN) and other research on this topic.147 answers were analyzed. 38% of the respondents modified their diet due to training. their most popular strategy was an additional pre-workout meal. in the group that did not modify the diet, the majority (82%) heard of some sport nutrition strategy. 52% of the respondents consumed a protein peri-workout meal. estimated 30% consume the amount of protein recommended by iSSN. Percentage of young sportspeople adjusting diet to training seems to be low, taking into account both established importance of such proceedings and awareness of sport nutrition strategies in this group. interestingly, more men than women do so. Group of respondents following well-documented iSSN recommendations is comparably modest. Perhaps the topic of nutrition strategies should be given more emphasis in schools and sport associations.

    Opis:
    The issue of talent selection and identification has been addressed by a variety of authors. However, few studies focus on sports recommended to be practiced by children on the basis of evaluating their performance or sports profiles. Material and Methods: The purpose of the study was to determine individual sports profiles of child athletes and nonathletes and recommend sports to be practiced. The participants were children aged 6 and 7 years who were first graders at elementary schools. Child athletes were children who participated in organized sports practice in soccer (n = 16), ice hockey (n = 29), and artistic gymnastics (n = 10). Child nonathletes (n = 26) did not participate in any organized sports practice within extracurricular activities or in sports clubs. Children performed a battery of 9 tests: sit-and-reach test, flexed arm hang (overhand grip), repeated routine with a stick, sit-ups, standing long jump, 4 x 10-meter shuttle run, rolling of three balls, 20-meter sprint and endurance shuttle run. To assess decision-making processes, children played a chasing game called "pull-the-flag" game. Results: As for the match between the sports practiced and the sports recommended to be practiced by child athletes, 20 children practiced the sports that were also recommended to be practiced on the basis of their individual sports profiles. According to their sports profiles, child nonathletes were recommended to do, in particular, rhythmic gymnastics, cycling, volleyball, tennis, and floorball. Conclusions: We may conclude that low number of children practice sports that match children's motor dispositions. Therefore, individual sports profiles need to be devised to provide children with recommendations concerning sports that match their talent.

    Opis:
    The aim was to assess an educational program about game statistics and a goal setting intervention in a community college women’s volleyball team. The sample consisted of 12 players from a Midwestern community college women’s volleyball team. A quasiexperimental design with a pre-test, post-test, and re-test was done. The dependent variable was the players’ perception and use of the game statistics. The independent variable was the educational program about game statistics and goal setting. The coaches’ and players’ perception, level of satisfaction, and completion of the task during the sessions were recorded. Data were collected through questionnaires and interviews. A descriptive and inferential analysis of the results (t-test for evidence of relationship) was done. After the educational training, the players’ perceptions of their ability to understand, analyse, and use information about game statistics and do goal setting in practice and in competition increased significantly. The players used the information significantly more in their practice for all the game actions. Players believed that the abilities they learned helped to improve their performance and the way they practiced. The players believed that the intervention was useful, that it helped them to focus in practice, and that it helped them to focus on technique and the quality of the actions, as well as to better monitor their progress. The educational program was effective with regard to increasing players’ perception and understanding about statistics and in the use of statistics and goal setting in practice for monitoring the quality of their actions and their progress.

    Opis:
    The aim of this study was to present the results of analyses conducted by means of complementary analytic tools in order to verify their efficacy and the hypothesis that Kohonen’s neural models may be applied in the classification process of swimmers. A group of 40 swimmers, aged 23 ±5 years took part in this research. For the purpose of verification of usefulness of Kohonen’s neural models, statistical analyses were carried out on the basis of results of the independent variables (physiological and physical profiles, specific tests in the water). In predicting the value of variables measured with the so called strong scale regression models, numerous variables were used. The construction of such models required strict determination of the endogenous variable (Y – results for swim distances of 200 m crawl), as well as the proper choice of variables in explaining the study’s phenomenon. The optimum choice of explanatory variables for the Kohonen’s networks was made on the grounds of regression analysis. During statistical analysis of the gathered material neural networks were used: Kohonen’s feature maps (data mining analysis). The obtained model has the form of a topological map, where certain areas can be separated, and the map constructed in this way can be used in the assessment of candidates for sports training.

    Opis:
    Peroxisome proliferator-activated receptor α (PPARα) is a transcription factor that regulates lipid and glucose metabolism. Accumulating evidence suggests that the intron 7 C allele of the PPARA gene rs4253778 G/C polymorphism has an advantage for power-oriented athletes, presumably due to the hypertrophic effects on skeletal muscle and increase in glucose utilization in response to anaerobic exercise. The G allele, however, is said to be favorable for the endurance-oriented athletes. The metabolic demands of team sports involve aerobic and anaerobic energy pathways, as a result of the intermittent physical activity. The aim of the present study was to investigate the association between the PPARA gene polymorphism and team-sport athletic status. A total of 665 Russian athletes from 14 team sports and 1,706 controls were involved in the case-control study. We found that the frequency of the PPARA C allele was significantly higher in athletes compared to controls (20.5 vs. 16.4%, P = 0.0009), suggesting that anaerobic rather than aerobic metabolism may be crucial to the game performance in team sports. This means that our study indicates the association between the PPARA gene G/C polymorphism and team-sport athletic status. Although more replication studies are needed, the preliminary data suggest an opportunity to use the analysis of PPARA polymorphism, along with other gene variations and standard phenotypic assessment in team sports selection.

    Opis:
    In the study, we tried to point out, on the basis of comparison conclusions of several research works, how much the psycho-physiological aspects contribute to influencing the conception of sport preparation in terms of the philosophical context of preparation in traditional martial arts. We elucidated the perception of the difference between martial arts and combat sports and emphasized the psychological dimension of training in sports karate in relation to physical training. At the same time, we were looking for relationships that would give us an answer as to which of these aspects are more effective in terms of sports performance. In conclusion, on the basis of a comprehensive content analysis of the findings, we draw attention to the fact that only the mutual correlation of both selected aspects can achieve the desired results in the training of karate practitioners.
    W naszym artykule, który ma charakter przeglądowy, porównaliśmy wnioski (wyniki badań) z kilkunastu artykułów o charakterze naukowym. Staraliśmy się wskazać, w jakim stopniu aspekty psychofizjologiczne w tradycyjnych sztukach walki są zaangażowane w projektowanie (planowanie i przygotowanie) treningu sportu w karate. Próbowaliśmy zbliżyć się do postrzegania różnicy pomiędzy sztukami walki a sportami walki, podkreślając psychologiczny wymiar treningu w karate sportowym w stosunku do treningu fizycznego. Jednocześnie szukaliśmy relacji, dających nam odpowiedź, który z tych aspektów jest bardziej skuteczny pod względem osiąganych wyników sportowych. W naszej analizie treści opracowań naukowych staraliśmy się podkreślić sposoby rozwoju osobowości i motywacji sportowca w kontekście treningu sportowego w dziedzinie karate. Podsumowując te rozważania, na podstawie pogłębionej i kompleksowej analizy treści ustaleń zwracamy uwagę na fakt, że tylko wzajemna korelacja obu wybranych aspektów może dać pożądane (zamierzone) wyniki sportowe w ramach treningu sportowego w karate.

    The thermal comfort properties of different knitted fabric structures made from modal, polypropylene and micro denier polyester were studied for volleyball sportswear. Eleven knitted fabrics were produced, in which three samples were single jersey, two plated and six bi-layer knitted structures. The air permeability, water vapour permeability, thermal conductivity, wicking and drying ability of bi-layer knitted fabric made up of polypropylene as the inner layer and modal as the outer layer with one tuck point of repeat were found to be higher as compared to other bi-layer, plated and single jersey structures. Both theobjective and subjective results show that bi-layer knitted fabric with polypropylene as the inner layer and modal as the outer layer with one tuck point of repeat is mostly suitablefor sportswear. The results are discussed together with multivariate ANOVA test results ata 95% significance level.
    Badano komfort cieplny różnych struktur dzianin wykonanych z włókien modalnych, polipropylenowych i mikrowłókien poliestrowych przeznaczonych na odzież sportową dla siatkarzy. Wytworzono jedenaście rodzajów dzianin, spośród których trzy miały splot lewo-prawy, dwie były platerowane, a sześć miało strukturę dwuwarstwową. Przepuszczalność powietrza i pary wodnej, przewodnictwo cieplne, zwilżalność („wicking”) i zdolność suszenia dwuwarstwowej dzianiny wykonanej z polipropylenowej warstwy wewnętrznej i zewnętrznej warstwy wykonanej z włókien modalnych okazały się najlepsze. Wyniki zostały poddane analizie statystycznej ANOVA przy 95% poziomie istotności.
