Os objetivos do presente estudo foram: 1) Verificar se há associação entre o nível de desempenho esportivo, maturação biológica e o gênero na Percepção Subjetiva de Esforço (PSE) do treinamento; 2) Verificar se treinadores conseguem estimar com precisão a PSE dos atletas na sessões de treinamento. Participaram do estudo 75 atletas de atletismo, com idade de 14,4 ± 0,8 anos, massa corporal de 55,8 ± 11,7 kg e estatura de 165,6 ± 9,0 cm. Todos tinham, pelo menos, seis meses de prática de atletismo e a maior parte treinava de 5 a 6 vezes por semana. O protocolo experimental durou 7 dias consecutivos, os seguintes testes foram utilizados para avaliar o desempenho esportivo no primeiro dia: Corridas de 75, 250 e 1000 metros, salto em distância e arremesso do peso. 48 horas depois foram prescritas e acompanhadas 5 sessões de treinamento de atletismo, uma para cada teste de desempenho, com intervalo de 24 horas entre elas. O estágio de maturação biológica foi avaliado pelo método do percentual da estatura matura predita (% EMP). Não houve associação estatisticamente significativa entre o nível de desempenho esportivo e a PSE; não houve diferença da PSE entre os grupos normaturos e avançados (meninos) atrasados e normaturos (meninas). Meninas indicam maior valor de PSE nos treinos de 250 e 1000 metros, quando comparadas aos meninos. Não houve diferença na PSE dos atletas com a estimada pelos treinadores (meninos, meninas e grupo todo), entretanto, não ocorreu também a concordância relativa as intensidades leve, moderada e pesada. Não houve concordância entre as intensidades em cada sessão. Treinadores de atletismo subestimam a intensidade leve e superestimam as intensidades moderada e pesada, quanto as meninas tem maior dificuldade para estimar as cargas. Os resultados indicam que a PSE não é influenciada pelo nível de desempenho esportivo e estágio maturacional, em atividades com característica de resistências de velocidade e aeróbia meninas indicam maiores valores de PSE e os treinadores não conseguem estimar com precisão a PSE dos atletas nas sessões de treinamento. / The sports training of young athletes need to be subsidized by accurate and reliable information on the intensity of training, biological maturity stage and how different groups react to training stimuli. The objectives of this study were: 1) Verify if there is an association between the level of sports performance, biological maturity and gender in Rate Perceived Exertion (RPE) training; 2) Make sure coaches can accurately estimate the RPE of athletes in training sessions. The study enrolled 75 athletes from track and field, aged 14.4 ± 0.8 years, body weight 55.8 ± 11.7 kg and 165.6 ± 9.0 cm tall. All were at least six months track and field practice and most practiced 5 to 6 times per week. The experimental protocol lasted 7 consecutive days, the following tests were used to evaluate sports performance on the first day: 75 races, 250 and 1000 meters, long jump and shot put. 48 hours were prescribed and monitored 5 track and field training sessions, one for each performance test, with 24-hour interval between them. The biological maturity stage was evaluated by the percentage of the method of predicted mature height (% PMH). There was no statistically significant association between the level of sports performance and the RPE; there was no difference between the RPE normaturos and advanced groups (boys) and late normaturos (girls). Girls RPE indicate greater value in training of 250 and 1000 meters, compared to boys. No differences in RPE athletes with estimated by the coaches (boys, girls and whole group), however, did not also occur to agreement on the mild, moderate and heavy intensities. There was no agreement between the intensities at each session. Track and Field trainers underestimate and overestimate mild moderate and heavy intensities, the girls find it more difficult to estimate loads. The results indicate that the RPE is not influenced by the level of sports performance and maturity stage, in activities with characteristic speed of resistance and aerobic girls indicate higher RPE values and the coaches can not accurately estimate the RPE athletes in training sessions .

O processo de recuperação pós-exercício é mediado por uma complexidade de fenômenos fisiológicos. Devido à diversidade de fenômenos fisiológicos envolvidos na recuperação autonômica cardíaca, tais como, catecolaminas, concentração de lactato, pH, amônia, temperatura, volume plasmático, etc., esse parâmetro tem sido utilizado como um indicador de recuperação no âmbito desportivo. Sabe-se que fatores como aptidão aeróbia e treinamento influenciam na recuperação autonômica cardíaca. Na presente dissertação, focou-se no estudo da recuperação autonômica cardíaca de jogadores de futsal. No primeiro estudo, investigou-se a influência do lastro do treinamento de futsal na recuperação da modulação autonômica cardíaca. Participaram deste estudo jogadores de futsal e indivíduos ativos com praticamente o mesmo nível de aptidão física dos atletas, com VO2máx de 49,4 ± 3,4 e de 50,1 ± 5,8 ml.kg.min-1, respetivamente. Avaliou-se a recuperação da modulação autonômica cardíaca nos cinco primeiros minutos de recuperação com a utilização do índice RMSSD30s normalizado, índice relacionado à atividade vagal. Observou-se que os jogadores de futsal apresentaram recuperação da modulação autonômica maior do que os indivíduos ativos a partir dos 90 s de recuperação (LnRMSSD30s 0,84 ± 0,43 e 0,64 ± 0,17 ms respectivamente). Neste estudo se observou, também, que os jogadores de futsal apresentaram reativação vagal, enquanto os indivíduos ativos apresentaram supressão vagal durante todos os cinco minutos da recuperação. Conclui-se que o treinamento do futsal, devido à dinâmica do jogo, aprimora a recuperação da modulação autonômica cardíaca. No segundo estudo, investigamos se o treinamento específico de curta duração, a pré-temporada, seria capaz de influenciar a recuperação autonômica cardíaca de jogadores de futsal. Foram avaliados nove jogadores de futsal, antes e após a prétemporadade quatro semanas. Neste estudo, avaliamos a recuperação do tônus vagal, identificada pela frequência cardíaca de recuperação (FCrec) e da modulaçãoautonômica cardíaca, identificada pela recuperação da variabilidade da frequência cardíaca (recVFC).A FCrec foi avaliada através dos valores absolutos de cada 30 segundos, enquanto que a recVFC foi avaliada pelo índice LnRMSSD2-5min. Observou-se que, após a pré-temporada, os atletas diminuíram a FCmáx em 7 bpm, diferença que foi percebida em quase todos os cinco minutos da recuperação. Além disso, a recVFC melhorou após a prétemporada o LnRMSSD2-5min no início da pré-temporada era de 1,00 ± 0,45 ms e passou para 1,29 ± 0,63 ms ao final da pré-temporada. Concluiu-se que a pré-temporada de treinamento específico e de curta duração em jogadores de futsal melhorou a recuperação autonômica cardíaca. / Indoor soccer is an intermittent sport with many pauses and substitutions during the match, which allows the recovery of physiological parameters during these moments, providing the player, to play at high intensity. The recovery process after the exercise is mediated by complex physiological phenomena. Due to the diversity of physiological phenomena involved in the recovery cardiac autonomic such as catecholamines, lactate concentration, pH, ammonia, temperature, plasma volume, etc. This parameter has been used as an indicator of recovery in sports. It is known that factors such as aerobic fitness and training influence the cardiac autonomic recovery. This dissertation focused on the study of cardiac autonomic recovery of indoor soccer players. In the first study, we investigated the influence of the coverage indoor soccer training on the recovery of cardiac autonomic modulation. Participated for the study indoor soccer players and active individuals with similar fitness level of athletes with VO2max of 49.4 ± 3.4 and 50.1 ± 5.8 ml.kg.min-1, respectively. We evaluated the recovery of cardiac autonomic modulation in the first five minutes of recovery using the index RMSSD30s normalized index related to vagal activity. It was observed that the soccer players showed recovery of autonomic modulation greater than active individuals from the 90 s recovery (LnRMSSD30s 0.84 ± 0.43 and 0.64 ± 0.17 ms respectively). In this study it was also noted that the soccer players showed vagal reactivation, as the active subjects had vagal suppression during all five minutes of recovery. We conclude that the training of indoor soccer, due to the dynamics of the game, improves recovery of cardiac autonomic modulation. In the second study, we investigated whether the specific training of short duration, the preseason, could influence the recovery of cardiac autonomic of futsal players. We evaluated nine players of indoor soccer, before and after the preseason of four weeks. In this study, we evaluated the recovery of vagal tone, identified by recovery heart rate (HRrec) and cardiac autonomic modulation, identified by the recovery of heart rate variability (recHRV). The HRrec was evaluated by the absolute values of every 30 seconds, while recHRV was evaluated by the index LnRMSSD2-5min. It was observed that after the preseason, athletes decreased in HRmax 7 bpm, difference has been seen in almost all five minutes of recovery. Moreover, recHRV improved after the preseason LnRMSSD2-5min early preseason was 1.00 ± 0.45 ms and increased to 1.29 ± 0.63 ms at the end of the preseason. It was concluded that specific and short-period preseason training in indoor soccer players improved cardiac autonomic recovery.

There exist a wide variety of metabolic responses to different types of carbohydrates and their influence on metabolism during endurance training. Recent studies revealed that the physiological responses to food are far more complex than was previously appreciated. The rapid release of insulin and the decline in blood sugar levels during the first stages of endurance training are linked to the Glycemic Index of foods. Researchers cannot still make use of the old distinction between starchy and sugary food or simple and complex carbohydrates. These distinctions are based on the chemical analysis of the food, which does not totally reflect the effects of these foods on the body. The Glycemic Index is a more reliable guideline to apply in nutritional management for endurance athletes. The major object of the study was to indicate the importance of utilizing the Glycemic Index (GI) as part of the nutritional preparation for endurance events. The study investigated the advantages of ingesting a Low Glycemic Index meal prior to exercise and compared it with the ingestion of a High Glycemic Index meal. A pretest-posttest design was used. Twelve healthy, male and female cyclists participated in the study. Subjects were selected according to their level of training. The total test period consisted of 14 days, which included two different dietary interventions of 7 days each. Diet -and training analysis were done on the subjects prior to the commencement of the study. Each subject completed three exercise trials. The first exercise trial consisted of a V02max test until exhaustion. Two submaximal trials (65 - 70 % of V02max) followed and were preceded by two dietary interventions. The dietary interventions (7 days each) had the same amount of CHO, fat and protein but differed in the Glycemic Index of the pre-exercise meals. The first pre-exercise meal was a High Glycemic Index (HGI) meal. The second pre-exercise meal was a Low Glycemic Index (LGI) meal. The results of the study indicated the advantages of ingesting a Low Glycemic Index meal prior to endurance exercise. The drop in blood glucose levels significantly differed (p<0.05) with an average of 0.68 mmol/L between the two tests after 10 minutes of cycling. It took 20 minutes for the blood sugar level of the first testto reach the same level of the blood sugar level of the second test. After the ingestion of the High Glycemic Index meal in Test 1, the blood lactate levels were significantly higher (p<0.05) during the first 15 minutes. The total distance covered by the subjects was 22.86 km after the first dietary intervention (High glycemic Index food) and 27.43 km after the second dietary intervention (Low glycemic Index food) although it is not statistically significant due to the small sample size. The difference in the distance covered of the two tests is 4.57 km in a period of 50 minutes. Subjects indicated that they experienced more physical strain (higher RPE values) in Test 1 (High Glycemic Index food) than in Test 2 (Low Glycemic Index food) (p<0.05). The study results support the fact that Low glycemic index food may confer an advantage when eaten prior to prolonged strenuous exercise by providing a slow¬releasing source of glucose to the blood without causing extensive hypoglycemia. Proper preparation and the correct choice of the pre-exercise meal can exclude the occurrence of sudden drops in the blood sugar levels. The Glycemic Index can also be successfully applied during and after events to improve performance. / Dissertation (MA (MHS))--University of Pretoria, 2007. / Arts, Languages and Human Movement Studies Education / unrestricted

Its largest part is dedicated to the training of goalkeepers in the age group 9 - 11 years, aiming to design the most suitable training program that would help them improve the level of their movement skills. The effectiveness of the training plan will be verified by motoric tests and the achieved results of the training sample will be compared with the results of the control sample.

In the first stages of long-term athlete development, the so-called multilateral development is recommended. It means that children should engage in a variety of different sports during their formative years. Multilateral development in children's sports training is associated with many benefits, such as injury prevention, psychosocial benefits, or transfer of motor skills. It is assumed that children with a higher level of multilateral development acquire specific sport skills faster and more easily than children with a lower level of multilateral development. However, there is a lack of prospective longitudinal studies that would prove or disprove the importance of multilateral development in children's sports training for specific sport skill acquisition. This dissertation aims to investigate the relationship between multilateral development and specific sport skill acquisition, specifically in ice hockey and athletics. This project is based on non-experimental longitudinal research and uses the tools of correlation analysis. We defined multilateral development indicators according to the study by Perič and Ružbarský (2019). For the proband selection, we used a purposive non-probability sampling method. In the first phase of the research, we assessed multilateral development in six- to...
