No caso do judô, como desporto acíclico com elevada exigência física, é importante mensurar tal esforço empregado pelos judocas de alto rendimento, para que tais indícios possam servir de ferramenta para uso dos técnicos, durante o cotidiano de trabalho. Sendo assim, o objetivo principal da pesquisa é de formular novo processo de avaliação física do atleta, denominado TC3 e TC15, de modo a responder às especificidades da modalidade, através de relações com o Special Judo Fitness Test (SJFT), proposta validada por Sterkowicz (1995) e situação de Luta, sendo esta a mais próxima da situação competitiva propriamente dita. O desempenho de 11 atletas, subdivididos em dois grupos, com diferentes desempenhos competitivos, foi mensurado através de quatro situações específicas do judô (SJFT, Luta, TC3 e TC15). Através da análise do desempenho motor (marcador externo) e da cinética da concentração do lactato sanguíneo ([Lac], marcador interno) pós-testes, postulou-se que tais variáveis possam explicar a condição física entre os atletas nessas situações. Os resultados mostraram que: houve diferença significante entre os grupos no desempenho do TC3 e TC15 e [Lac] no TC3; não houve diferença significante entre o desempenho no SJFT, mostrando que o SJFT não discriminou grupos de atletas com desempenho competitivo diferenciado, conforme afirma Sterkowicz (1995); TC3 apresentou alta fidedignidade; TC3 e TC15 apresentou correlação e concordância com resultados apresentados pelo SJFT. Através desses resultados, concluiu-se que as novas propostas de avaliação físicas são aplicáveis e que podem ser utilizadas como parâmetro do desempenho de atletas de judô / Abstract: In the actual sporting scenery, the need to establish a reliable method of controlling the athlete training is one of the main concerns of science sports researches. In the case of judo, a sport with a high physical demand is important to measure the effort required by the high-performance athlete so that the sign can be used as a tool for the coach during their work. As a consequence, the most important point of this research is to formulate a new physical evaluation process, denominated TC3 and TC 15. To answer all specifications of its classification through the relations with Special Judo Fitness Test (SJFT), this proposal was validated by Sterkowicz (1995), and fight simulation, being the closest to the competitive situation. The performance of 11 athletes, divided in 2 groups, with different competitive performance, was mentioned by 4 specific situations of judo (SJFT, fight, TC3 and TC15) through the analysis of performance (external marker) and kinetics of blood lactate concentration (internal marker) tests concluded that such variable could explain the physical condition among athletes. The outcome showed that: there was a significant difference among the performance of groups TC3 and TC15, but there wasn¿t a significant difference among SJFT groups. Therefore, SJFT didn¿t make distinction on those groups with a better competitive performance, according to Sterkowicz (1995); TC3 had a high reliability; TC3 and TC15 showed correlation and harmony with the results presented by SJFT. According to this, we can conclude that the new proposals of physical evaluation are applicable and can be used as a reference to the athlete¿s performance / Mestrado / Ciencia do Desporto / Mestre em Educação Física

The problem addressed is the lack of empirical research describing the delivery of individualized learning material in a secure and mobile manner. The goal was to investigate the effectiveness of deploying training materials to National Football League (NFL) players during a recent NFL season. Over the past few seasons, NFL teams have started to deliver player training material to mobile devices. The training material is sensitive and includes planning documents for upcoming games. An effort was made to survey a representative at each of the 32 NFL teams in order to gain insight on effectiveness, security, and process. Nearly half of the league responded with 14 of the 32 franchises reporting back. The results demonstrate that mobile devices can be an effective means to distribute educational materials to individuals in secure manner. The iPad was identified as a suitable platform for delivery of instructional material. Security elements such as encryption and using mobile security products should be strongly considered. The results are discussed in detail. A set of standards and guidelines were created based on the responses provided by club employees.

Thesis (M Sport Sc)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: This study investigated the optimal training load required for peak-power production in two types of exercises, namely an Olympic-type and a ballistic exercise. The hang clean and the squat jump were selected to represent these two types of exercise. It was ascertained whether a change in strength levels and training status will have an effect on the optimal loads for peak-power production of rugby players. In addition, the influence that different playing positions have on power production was also investigated. Fifty-nine under-21 male rugby players (Mean Age 19.3yrs; SD ± 0.7yr) from two rugby academies, performed a maximal-strength test in the hang clean and squat, followed by a power test in the hang clean and squat jump with loads ranging from 30 to 90% of maximal strength (1RM). Testing was conducted in the pre-season phase and repeated during the inseason phase. Peak power for the hang clean was achieved at 90% 1RM in the pre-season and at 80% 1RM during the in-season. Peak power for the squat jump was achieved at 90% 1RM in the pre-season. However, this location of the optimal loading was not significantly higher than that of the other loadings (60, 70 and 80% 1RM). During the in-season, peak power for the squat jump was reached at 90% 1RM. Here again, the optimal-loading location was not significantly higher than that of the other loadings (50, 60, 70 and 80% 1RM). It was concluded that the optimal load for power production is 90% 1RM for the hang clean and 60-90% for the squat jump. It was found that an improvement in strength levels of the subjects affected both peak-power production and the optimal load in both exercises. During the in-season peak power in the hang clean was reached at 80% 1RM, and at 50% 1RM for the squat jump. There were no significant differences in the performances of subjects from different playing positions (forwards versus backline players). In the hang clean, peak-power production seems to be reliant on increased strength and results in peak-power output at high loads. The squat jump, on the other hand, is more reliant on velocity due to its ballistic nature and is possibly better suited to developing power at lighter loadings. Because it produces peak power at a lower percentage load than the hang clean, the squat jump could be more effective in power development for players who are inexperienced in power training. Long-term exercise periodisation in power training can therefore be employed progressively from simpler exercises (e.g., squat jump) using only the legs, to more complex exercises (e.g., Olympic-lifting) that involve the whole body. This study confirmed that the specific requirements of different sport codes should be considered meticulously before selecting and prescribing exercises and loads for power-training programmes. / AFRIKAANSE OPSOMMING: Die hooffokus van hierdie studie was op die optimale oefenlading wat vereis word vir die produsering van piek-profkrag tydens die uitvoering van twee tipes oefening, naamlik ’n Olimpiese- en ’n ballistiese oefening. Die hang clean en die squat jump is geselekteer om bogenoemde twee tipes oefening te verteenwoordig. Daar is bepaal of ’n verbetering van die krag-vlakke en oefenstatus van rugbyspelers ’n invloed het op die optimale ladings vir piek-plofkrag ontwikkeling. Verder is die moontlike rol van verskillende speelposisies ondersoek. Nege-en-vyftig onder-21 mans-rugbyspelers (M-ouderdom 19.3jr; SD ± 0.7jr) vanuit twee rugbyakademies het ’n maksimale-krag toets in die hang clean en squat uitgevoer. Dit is opgevolg deur ’n plofkrag-toets in die hang clean en squat jump met ladings wat gewissel het van tussen 30 en 90% van maksimale werkverrigting (1RM). Toetsing het plaasgevind in die voor-seisoen fase en is herhaal tydens die daaropvolgende speelseisoen. Piek-plofkrag vir die hang clean is bereik tydens ’n oefenlading van 90% 1RM in die voor-seisoen en by 80% 1RM later in die speelseisoen. Piek-plofkrag vir die squat jump is behaal by 90% 1RM in die voor-seisoen fase. Hierdie optimale lading-lokasie was egter nie beduidend hoër as by die ander ladings van 60, 70 en 80% 1RM nie. Tydens die speelseisoen is piek-plofkrag bereik in die squat jump by 90% 1RM. Die optimale lading-lokasie was weereens nie beduidend hoër as by die ander ladings van 50, 60, 70 en 80% 1RM nie. Daar is tot die gevolgtrekking gekom dat die optimale oefenlading vir die ontwikkeling van piek-plofkrag vir die hang clean 90% 1RM is, en 60% vir die squat jump. Daar is ook gevind dat ’n verbetering in kragvlakke van die toetslinge, beide piek-plofkrag-produksie en die optimale oefenbelading in albei oefeninge beïnvloed. Tydens die speelseisoen is piek-plofkrag behaal in die hang clean by 80% 1RM, en by 50% 1RM in die squat jump. Geen beduidende verskille in werkverrigting is gevind tussen toetslinge uit verskillende speelposisies (voorspelers versus agterlyn-spelers) nie. Dit blyk dat in die hang clean, die produksie van plofkrag beïnvloed word deur ’n verbetering in krag en dat dit tot hoër optimale ladings vir piek-plofkrag produksie lei. Die squat jump, in teenstelling, is meer afhanklik van snelheid en is moontlik beter geskik vir die produsering van plofkrag teen ligter oefenladings. Omdat die squat jump piek-plofkrag genereer teen laer ladings as die hang clean, kan dit meer effektief wees vir spelers met gebrekkige ervaring in krag-oefening. Lang-termyn oefen-periodisering in plofkrag-oefening kan gevolglik progressief aangewend word vanaf eenvoudiger oefeninge (bv. squat jump), waar slegs die bene gebruik word, tot meer komplekse oefeninge (bv. Olimpiese-gewigoptel) waar die hele liggaam betrek word. Hierdie studie bevestig dat die spesifieke vereistes van verskillende sportkodes deeglik oorweeg moet word alvorens oefeninge en ladings geselekteer en voorgeskryf word vir plofkrag-programme.

This study examined the effects of two distinct phases of endurance training (summer and in-season training) in previously well-trained male and female high school cross-country runners. Eleven males and 11 females from the same high school training program were recruited for the three testing sessions: post-track season (June), postsummer training (mid-August), and post-cross-country season (early-November). However, due to injury and other circumstances, only 10 males and 4 females completed all testing sessions. Thus, baseline characteristics were analyzed for both genders; however, longitudinal analysis was only conducted using the males. Submaximal measurements included running economy (RE), blood lactate concentration ([BLa]), and heart rate (HR) at three running speeds in females (6, 7, and 8 mph), and males (7, 8, and 9 mph). Maximal measurements of oxygen uptake (VO2max) and HR, neuromuscular characteristics of isokinetic knee extension strength and vertical jump height, and body composition were also measured. Baseline results showed that the males possessed a higher VO2max, greater neuromuscular characteristics, and lower submaximal [BLa] and HR values than the females. Longitudinal analysis of the males showed that there was an increased VO2max, decreased maximal HR, and decreased neuromuscular strength following summer training. In-season training precipitated further increases in VO2max, an increase in maximal and submaximal HR, and increased neuromuscular characteristics. RE and [BLa] did not significantly change (p<_ 0.05) throughout the course of the study. Likely, it is the subtle changes in these variables in previously welltrained runners which account for the slower performance times at the beginning of the cross-country season and the improvements thereafter. / School of Physical Education

Title Training and performance of a shot put thrower Aim of study The aim of study was to analyze performance development of shot put thrower Pavlína Radová in a five-year period. Analysis was focused on connection between the dynamics of athletic performance and the effect of training load during each of the two training cycles 2010/2011 and 2011/2012. Methods In this thesis, we used auto-analysis and comparison. Data for analysis of training load and performance development were obtained from the training diaries of the years 2010/2011 and 2011/2012. Results Sports performance development was majorly affected by character of training load and mental condition of the athlete in each yearly training cycle. Poorly chosen training load and insufficient regeneration lead to stagnation or decline in physical performance. Individual approach of the coach and his communication with trainee is very important. Key words Sports training, shot put, performance, analysis, training load

Title: Training and competitive activity in the age category minitenis. Objectives: Description, analysis and subsequent evaluation of the training process and competitive activity in the age category minitenis Methods: Observation, document analysis , interview with using the instructions Results: From the first part of the interview it was obvious that five of six surveyed persons recruit efficiently in a way that gets results. The second part of the interview was focused on the organization and layout of the training itself. I discovered that coaches are trying to lead their training sessions in initiative way. Composition of their training is in accordance with the general principles of sports training. From the result of the third part arise that the half of the couches do not prefer to involve such small children in competitions of individuals but rather they encourage matches played in teams.
