A amostra foi constituída de 10 atletas (25 ± 4 anos) que participaram do XI Campeonato Brasileiro de Basquetebol Feminino. Foram avaliados o comportamento da frequência cardíaca (FC) e a percepção subjetiva de esforço (PSE) em resposta à partida. A carga interna foi calculada pelo método de Edwards e pelo método de Foster. Além disso, foram analisados os parâmetros de desempenho técnico na partida. A carga interna estimada pelo método de Edwards e Foster foram 255±62 e 321±127 unidades arbitrárias, respectivamente. Foi detectada correlação moderada entre os dois métodos utilizados (Edwards e Foster; r = 0,64;-p<0,05). Também foram detectadas correlações significativas (p<0,05) entre a carga interna estimada pelo método de Edwards e o número de pontos marcados na partida (r = 0,53), o número de rebotes (r = 0,67), o número de assistências (r = 0,59), o número de recuperações de posse de bola (r = 0,70) e o somatório de todas as ações (r = 0,64). Os resultados obtidos no presente estudo sugerem que a carga interna da partida avaliada foi moderada e que o número de ações realizadas pelas atletas na partida influencia a carga interna. Palavras-chave: Percepção subjetiva do esforço; Frequência cardíaca; Basquetebol.

High-school wrestlers (females: n = 16, 13 6 2 years; males: n = 15, 13 6 2 years) participated in this study. The official weigh-in was conducted 24 hours before competition. Immediately after the official weigh-in, wrestlers completed a hydration habits and a standardized weight loss questionnaires. Twenty-four hours later, wrestlers took part in an unofficial prematch weigh-in. Sodium, potassium, chloride, hematocrit, and hemoglobin were measured immediately before the first competitive match by iSTAT Blood Gas Analyzer. A significant body mass increase was observed from the official weigh-in to the prematch weigh-in (females: 2.7 6 1.4 kg and males: 1.5 6 0.9 kg; p # 0.05) with significantly greater body mass increase in females (6.3%) vs. males (3.1%) (p # 0.05). Rapid weight loss practices were exercised by 42.0% of the wrestlers. Furthermore, 46.2% of those who performed RWL practices reported side effects, which they perceived negatively altered past performance. Despite RWL and subsequent body mass increase, all biomarkers (sodium, potassium, chloride, hematocrit, and hemoglobin) were in the normal range at the prematch weigh-in. The majority (82.0%) of the athletes agreed that hydration habits are important to health and performance. It seems that although wrestlers acknowledge negative performance effects due to RWL, the practice is still exercised among both female and male wrestlers. Therefore, educational programs should be implemented in high-school athletes to discourage RWL and provide information for exercise and nutritional strategies to maintain a healthy body mass and avoid chronic health issues.

Seventy individuals with ages ranging from 20 and 30 years with no previous flexibility training participated in this study. Randomly, 10 subjects composed the control group (CG) and the others were equally divided into three groups according to the duration of the stimulus, namely: 10 seconds (G10), 60 seconds (G60) and 120 seconds (G120). Later, each group was subdivided in relation to the number of series, namely: one (G10A, G60A, G120A) and three series (G10B, G60B, G120B). Flexibility was measured through an universal goniometer and the observations occurred shortly after, 90 minutes after and 24 hours after stimulation. The analysis of variance ANOVA identified significant association between the time of stimulus and the other variables (p = 0.042). No differences of flexibility were verified between experimental groups, but all groups exhibited values higher than CG. The temporal comparison of absolute values of flexibility for groups submitted to the same stimulus duration and number of series revealed significant differences only for G120A, G60B and G120B, between the first observation and 24 hours after. On the other hand, the analysis of the percentile values showed that the stimulation time and the number of series were associated with the duration of the flexibility acute increment. In this case, no differences between groups were verified, except between G60A and G60B in the observation after 24 hours. One concludes that stimulus duration may provide higher initial flexibility, regardless the number of series. However, the immediate gains of flexibility could not be maintained after 24 hours. No one knows, however, if progressive long-duration stimuli would provide long-term higher amplitude if compared with stretching exercises performed in shorter periods of time.

The concern about the training load control is actually intrinsic both to the academic community and the professionals who participate in the Sports routine. Undoubtedly, the search for solutions for the reliable monitoring of the training load, in a more accessible and coherent with the demands of a practice based on evidence, is a crucial issue. Six points have been mentioned in the letter which will be treated accordingly, following the order they were presented. We also thank for the opportunity to clarify and explain some aspects which may have not been suitably presented/ discussed in the original article. Before we start the discussion on the six topics, it is first important to mention that we did not intend to question in any moment the quality of the prescribed training by the coaches who participated in our study 1 . The success of this modality in the international scenario (World Championships and Olympic Games) is unquestionable. Judo is responsible for considerable number of Olympic medals won by Brazil, and was behind only Sailing. Therefore, it is necessary to clarify that the results interpretation presented in our article 1 does not go through reflexion/ judgment on the quality of the Judo training, not only for not being the aim in our study but also for its delimitations would not enable such inferences and generalizations. In the Letter to the Editor it is suggested that “the conclusion is at first surprising”; however, we do not understand the reason for the “surprise”. This excerpt of the Letter to the Editor seems to reflect much more a personal and specific opinion of its authors rather than effectively a hypothesis. The formulation of a reasonable hypothesis, based on previous investigation on the theme, would be existence of incompatibility in the perception concerning the training load intensity between coaches and athletes. Studies previously published in other sports modali

A amostra foi composta por quatro técnicos e 40 atletas da Seleção Brasileira de Judô. A comparação entre a intensidade planejada e a intensidade experienciada foi realizada através da aplicação do método da percepção subjetiva do esforço (PSE) da sessão durante um training camp. Também foram realizadas coletas de sangue para determinação da concentração de lactato sanguíneo. A intensidade da carga de treinamento reportada pelos atletas superou a intensidade planejada pelos técnicos em todas sessões de treinamento. Com relação à concentração de lactato, houve aumento no período pós-treino em todas as sessões do training camp, não havendo diferença entre as sessões. Os resultados do presente estudo demonstram que, embora o programa de treinamento tenha sido elaborado por técnicos experientes, fo...

This study evaluated the biochemical and hematological responses of a male world-class athlete in sailing who is ranked among the top athletes on the official ISAF ranking list of windsurfing, class RS:X. The results describe the metabolic adaptations of this athlete in response to exercise in two training situations: the first when the athlete was using the usual training and dietary protocol, and the second following training and nutritional interventions based on a careful analysis of his diet and metabolic changes measured in a simulated competition. The intervention protocol for this study consisted of a 3-month facility-based program using neuromuscular training (NT), aerobic training (AT), and nutritional changes to promote anabolism and correct micronutrient malnutrition. Nutritional and training intervention produced an increase in the plasma availability of branched-chain amino acids (BCAAs), aromatic amino acids (AAAs), alanine, glutamate, and glutamine during exercise. Both training and nutritional interventions reduced ammonemia, uricemia, and uremia. In addition, we are able to correct a significant drop in potassium levels during races by correct supplementation. Due to the uniqueness of this experiment, these results may not apply to other windsurfers, but we nonetheless had the opportunity to characterize the metabolic adaptations of this athlete. We also proposed the importance of in-field metabolic analyses to the understanding, support, and training of world-class elite athletes.

Fourteen female basketball players each performed an endurance scheme (ES-4 sets of 12 reps, 60% of 1 repetition maximum (1RM) load, 1-minute rest periods), a strength-hypertrophy scheme (SHS-1 set of 5RM, 1 set of 4RM, 1 set of 3RM, 1 set of 2RM, and 1set of 1RM with 3-minute rest periods, followed by 3 sets of 10RM with 2-minute rest periods) and a power scheme (PS-3 sets of 10 reps, 50% 1RM load, 3-minute rest periods) using the same exercises (bench press, squat, and biceps curl). Saliva samples were collected at 07:30 hours, pre-exercise (Pre) at 09:30 hours, postexercise (Post), and at 17:30 hours. Matching samples were also taken on a nonexercising control day. The samples were analyzed for testosterone, cortisol (C), and immunoglobulin A concentrations. The total volume of load lifted differed among the 3 schemes (SHS &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; ES &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; PS, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). Postexercise C concentrations increased after all schemes, compared to control values (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). In the SHS, the postexercise C response was also greater than pre-exercise data (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). The current findings confirm that high-volume resistance exercise schemes can stimulate greater C secretion because of higher metabolic demand. In terms of practical applications, acute changes in C may be used to evaluate the metabolic demands of different resistance exercise schemes, or as a tool for monitoring training strain.

Setenta indivíduos com idade entre 20 e 30 anos sem treinamento prévio em flexibilidade participaram do estudo. Aleatoriamente, 10 sujeitos compuseram o grupo controle (GC) e os demais foram divididos igualmente em três grupos, de acordo com a duração do estímulo, a saber: 10 segundos (G10), 60 segundos (G60) e 120 segundos (G120). Posteriormente, cada grupo foi subdivido em relação ao número de séries, a saber: uma (G10A, G60A, G120A) e três séries (G10B, G60B, G120B). A flexibilidade foi medida por um goniômetro universal e as observações ocorreram imediatamente após, 90 minutos após e 24 horas depois do estímulo. A ANOVA identificou associação significativa entre o tempo de estímulo e demais variáveis (p = 0,042). Não se verificaram diferenças de flexibilidade entre os grupos experimentais, ma...

A precise understanding of the TLs completed during training is crucial to achieve desirable training outcomes and to avoid overtraining. TL can be monitored in many different ways; however, we recommend the session-rate of perceived exertion (session-RPE) method for quantifying TL because of its low cost and because it is easy to understand and relatively simple to implement. In this report, we provide data regarding TLs collected during the 2008 Roland Garros Tournament. Our experience in tennis suggests the session-RPE method to be a valuable tool that can be used to control training and to avoid excessive TLs. We also believe that accurate monitoring of TL will enable the coach to better understand of the sports training process, ultimately leading to the improvement of performance.

Seventy individuals with ages ranging from 20 and 30 years with no previous flexibility training participated in this study. Randomly, 10 subjects composed the control group (CG) and the others were equally divided into three groups according to the duration of the stimulus, namely: 10 seconds (G10), 60 seconds (G60) and 120 seconds (G120). Later, each group was subdivided in relation to the number of series, namely: one (G10A, G60A, G120A) and three series (G10B, G60B, G120B). Flexibility was measured through an universal goniometer and the observations occurred shortly after, 90 minutes after and 24 hours after stimulation. The analysis of variance ANOVA identified significant association between the time of stimulus and the other variables (p = 0.042). No differences of flexibility were verified between experimental groups, but all groups exhibited values higher than CG. The temporal comparison of absolute values of flexibility for groups submitted to the same stimulus duration and number of series revealed significant differences only for G120A, G60B and G120B, between the first observation and 24 hours after. On the other hand, the analysis of the percentile values showed that the stimulation time and the number of series were associated with the duration of the flexibility acute increment. In this case, no differences between groups were verified, except between G60A and G60B in the observation after 24 hours. One concludes that stimulus duration may provide higher initial flexibility, regardless the number of series. However, the immediate gains of flexibility could not be maintained after 24 hours. No one knows, however, if progressive long-duration stimuli would provide long-term higher amplitude if compared with stretching exercises performed in shorter periods of time.

The concern about the training load control is actually intrinsic both to the academic community and the professionals who participate in the Sports routine. Undoubtedly, the search for solutions for the reliable monitoring of the training load, in a more accessible and coherent with the demands of a practice based on evidence, is a crucial issue. Six points have been mentioned in the letter which will be treated accordingly, following the order they were presented. We also thank for the opportunity to clarify and explain some aspects which may have not been suitably presented/ discussed in the original article. Before we start the discussion on the six topics, it is first important to mention that we did not intend to question in any moment the quality of the prescribed training by the coaches who participated in our study 1 . The success of this modality in the international scenario (World Championships and Olympic Games) is unquestionable. Judo is responsible for considerable number of Olympic medals won by Brazil, and was behind only Sailing. Therefore, it is necessary to clarify that the results interpretation presented in our article 1 does not go through reflexion/ judgment on the quality of the Judo training, not only for not being the aim in our study but also for its delimitations would not enable such inferences and generalizations. In the Letter to the Editor it is suggested that “the conclusion is at first surprising”; however, we do not understand the reason for the “surprise”. This excerpt of the Letter to the Editor seems to reflect much more a personal and specific opinion of its authors rather than effectively a hypothesis. The formulation of a reasonable hypothesis, based on previous investigation on the theme, would be existence of incompatibility in the perception concerning the training load intensity between coaches and athletes. Studies previously published in other sports modali

A amostra foi composta por quatro técnicos e 40 atletas da Seleção Brasileira de Judô. A comparação entre a intensidade planejada e a intensidade experienciada foi realizada através da aplicação do método da percepção subjetiva do esforço (PSE) da sessão durante um training camp. Também foram realizadas coletas de sangue para determinação da concentração de lactato sanguíneo. A intensidade da carga de treinamento reportada pelos atletas superou a intensidade planejada pelos técnicos em todas sessões de treinamento. Com relação à concentração de lactato, houve aumento no período pós-treino em todas as sessões do training camp, não havendo diferença entre as sessões. Os resultados do presente estudo demonstram que, embora o programa de treinamento tenha sido elaborado por técnicos experientes, fo...

This study evaluated the biochemical and hematological responses of a male world-class athlete in sailing who is ranked among the top athletes on the official ISAF ranking list of windsurfing, class RS:X. The results describe the metabolic adaptations of this athlete in response to exercise in two training situations: the first when the athlete was using the usual training and dietary protocol, and the second following training and nutritional interventions based on a careful analysis of his diet and metabolic changes measured in a simulated competition. The intervention protocol for this study consisted of a 3-month facility-based program using neuromuscular training (NT), aerobic training (AT), and nutritional changes to promote anabolism and correct micronutrient malnutrition. Nutritional and training intervention produced an increase in the plasma availability of branched-chain amino acids (BCAAs), aromatic amino acids (AAAs), alanine, glutamate, and glutamine during exercise. Both training and nutritional interventions reduced ammonemia, uricemia, and uremia. In addition, we are able to correct a significant drop in potassium levels during races by correct supplementation. Due to the uniqueness of this experiment, these results may not apply to other windsurfers, but we nonetheless had the opportunity to characterize the metabolic adaptations of this athlete. We also proposed the importance of in-field metabolic analyses to the understanding, support, and training of world-class elite athletes.

Fourteen female basketball players each performed an endurance scheme (ES-4 sets of 12 reps, 60% of 1 repetition maximum (1RM) load, 1-minute rest periods), a strength-hypertrophy scheme (SHS-1 set of 5RM, 1 set of 4RM, 1 set of 3RM, 1 set of 2RM, and 1set of 1RM with 3-minute rest periods, followed by 3 sets of 10RM with 2-minute rest periods) and a power scheme (PS-3 sets of 10 reps, 50% 1RM load, 3-minute rest periods) using the same exercises (bench press, squat, and biceps curl). Saliva samples were collected at 07:30 hours, pre-exercise (Pre) at 09:30 hours, postexercise (Post), and at 17:30 hours. Matching samples were also taken on a nonexercising control day. The samples were analyzed for testosterone, cortisol (C), and immunoglobulin A concentrations. The total volume of load lifted differed among the 3 schemes (SHS &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; ES &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; PS, p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). Postexercise C concentrations increased after all schemes, compared to control values (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). In the SHS, the postexercise C response was also greater than pre-exercise data (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.05). The current findings confirm that high-volume resistance exercise schemes can stimulate greater C secretion because of higher metabolic demand. In terms of practical applications, acute changes in C may be used to evaluate the metabolic demands of different resistance exercise schemes, or as a tool for monitoring training strain.
