    Aim. This study aims to compare the perception of the intensity of the training load planned by a coach with the training intensity perception of youth swimmers. Methods. The subjects were 17 athletes with a mean age of 15.2±0.57 years, body mass 59.7±5.7 kg and height 170.1±6.3 cm. Every day before the training session, the coach answered the Ratio of Perceived Exertion (RPE) scale for his workout planned for that day, and at the end of each session, the athletes answered the same scale. The training sessions were divided as proposed by Foster et al.,8 according to the desired intensity by the coach as follows:RPE<3, lightweight training; 3-5, moderate training; > 5, heavy training. The statistical program SPSS (version 19.0) and a significance level of 5% were used for all analyses. Results. The results indicate that, despite a team of young competitive swimmers who were presented with a consistent and carefully planned training program, there may be differences between the coach’s and athletes’ perceptions, especially in moderate intensity sessions and during tapering. Conclusion. These data reinforce the need for the careful monitoring/control of training loads in order to avoid major differences between these perceptions.

    The present study aimed to evaluate the effect of a school soccer competition with consecutive day games on the recovery status of U-19 players. Thirty-one school athletes (17.1±1.1 years) who played a U-19 school soccer competition (composed of two groups of four soccer teams each, followed by semifinals and final) were randomly evaluated. Games lasted 70 min (two periods of 35 min with 15 min rest interval), and they were played on consecutive days with 24 h between each game. Delayed onset muscle soreness (DOMS) and Total Quality Recovery (TQR) were measured before group phase games (n= 31) and semifinals games (n= 18). The internal game load was measured by the session rate of perceived exertion (session-RPE) method. TQR was higher before the first game when compared to the other games (p< 0.001). DOMS increased after the first game and did not return to baseline before the fourth game. Both session-RPE and internal load of the fourth game were higher than in the other games (p< 0.001). In addition, there was no correlation between internal game load and TQR (p> 0.05). The monotony observed during the evaluated period was 3.1±2.0 AU. The results indicate that the 24 h rest period seems to be insufficient for complete recovery of U-19 soccer school athletes, suggesting the organization of U-19 school soccer competitions with higher rest interval between games and search for methods to increase the recovery rate.

    Improvement of physical performance, hormonal profile, recovery-stress balance and increase of muscle damage in a specific futsal pre-season planning.
    (2018) Nogueira, Francine Caetano de Andrade; Freitas, Victor Hugo de; Nogueira, Ruan Alves; Dias, Bernardo Miloski; Werneck, Francisco Zacaron; Bara Filho, Maurício Gattás
    Objective: The aim of this study was to verify the effects of a specific pre-season planning on physical performance, recovery-stress state, hormonal and muscle damage markers in high-level futsal players. Method: Fifteen male futsal players, members of a high level Brazilian futsal team participated in this study. Before and after four weeks of pre-season, blood samples were collected, the Recovery Stress Questionnaire for Athletes was applied, and vertical jump tests and Yo-Yo Intermittent Recovery Level 2 tests were performed. The Internal Training Load was measured in alltraining sessions. Repeated measure ANOVA was used to compare the Total Weekly Training Load between different weeks. To compare the differences between pre- and post-training of all other dependent variables (except the Recovery Stress Questionnaire for Athletes scales) the Student’s t-test and the magnitude based inference were used. Results: The futsal pre-season improved performance in the Yo-Yo Intermittent Recovery Level 2 and Squat Jump tests. The improvement in performance tests was accompanied by an increase in testosterone, creatine kinase, testosterone/creatine kinase ratio and in the majority of the Recovery Stress Questionnaire for Athletes scales. Cortisol and the social recovery and general well-being of Recovery Stress Questionnaire for Athletes scales decreased during the futsal pre-season. Conclusions: In summary, players improved their performance in the Yo-Yo Intermittent Recovery Level 2 and Squat Jump tests in response to a futsal pre-season. Furthermore, the Internal Training Load behavior of the futsal training promoted a favorable hormonal anabolic environment and did not promote a negative disturbance in creatine kinase or stress/recovery balance, suggesting that futsal players did not report fatigue accumulation after this pre-season design.

    Influência das cargas de treinamento sobre o rendimento e os níveis de recuperação em nadadores.
    (2015) Nogueira, Francine Caetano de Andrade; Nogueira, Ruan Alves; Dias, Bernardo Miloski; Cordeiro, André Henrique de Oliveira; Werneck, Francisco Zacaron; Bara Filho, Maurício Gattás
    Este estudo verificou o comportamento do estado de recuperação e dos níveis de rendimento em função das cargas externas e internas em atletas juvenis de natação. Participaram do estudo 17 atletas pertencentes a um clube de Minas Gerais. Para testar as diferenças entre as quatro semanas analisadas, entre o rendimento e entre os valores do RESTq, foi utilizada ANOVA para medidas repetidas e entre o estado de recuperação dos atletas nas duas fases, foi utilizado o teste t de Student para amostras pareadas. Utilizou-se o programa estatístico Statistica (versão 8.0) e nível de significância de 5%. Os resultados mostraram que as variáveis de carga interna e de carga externa diminuíram da Fase da Transformação para a Fase de Polimento. Ao contrário, os níveis de recuperação aumentaram. Entretanto, o rendimento não se alterou entre as três competições e, durante a competição principal, não houve alteração significativa na relação recuperação-estresse do RESTq.

    Relationship between training volume and ratings of perceived exertion in swimmers.
    (2016) Nogueira, Francine Caetano de Andrade; Freitas, Victor Hugo de; Dias, Bernardo Miloski; Cordeiro, André Henrique de Oliveira; Werneck, Francisco Zacaron; Nakamura, Fábio Yuzo; Bara Filho, Maurício Gattás
    The markers of external training load (ETL), distance and intensity, do not take into account the athletes’ psychophysiological stress, i.e., internal training load (ITL). Thus, the aim of this study was to evaluate the relationship between ETL and ITL using the rating of perceived exertion (RPE) and session-RPE in swimmers. Seventeen young swimmers (10 male, 15.8 0.87 yr and 7 female, 15.1 0.46 yr) belonging to one national level youth team took part in this study over 4 wk. The external training load was planned using swimming distance (in meters) at seven different training intensities. Swimmers’ RPE was assessed 30 min after each training session. Session-RPE was calculated by multiplying RPE by session duration (min). The relationship between the variables was analyzed with Pearson correlations and a multiple linear regression was performed to predict the session-RPE as a function of the independent variables (aerobic and anaerobic volume). The swimming distance at different intensities correlated strongly with RPE and very largely with session-RPE (.64, p<.05 and .71, p<.05, respectively). Regression analysis indicated that the aerobic and anaerobic volumes together explained more than 50% of the ITL variability. In conclusion, the swimming distance in each training session was significantly associated with RPE and session-RPE in swimmers. In other words, based on these results, the use of high-volume training at lower intensities affects the RPE and Session-RPE more than the anaerobic volume.

    (2020) Debien, Paula Barreiros; Dias, Bernardo Miloski; Werneck, Francisco Zacaron; Timoteo, Thiago Ferreira; Ferezin, Camila; Bara Filho, Maurício Gattás; Gabbett, Tim J.
    Context: Rhythmic gymnastics requires a high level of complexity and perfection of technical gestures, associated with well-developed physical and artistic capacities. The training-load and recovery profiles of rhythmic gymnasts across a season are unknown. Objective: To analyze the training load and recovery of professional rhythmic gymnasts during 1 season. Design: Cohort study. Setting: Brazilian National Training Center of Rhythmic Gymnastics and competition facilities. Patients or Other Participants: Eight gymnasts from the Brazilian national senior rhythmic gymnastics group. Main Outcome Measure(s): Session rating of perceived exertion (session-RPE) and total quality recovery (TQR) scores were collected daily for 43 weeks. We obtained the session-RPE after each session and TQR score before the first session of the day. Performances during 5 competitions were also recorded. The season was divided into 8 periods. Total weekly internal training load (wITL), training intensity, frequency, duration, recovery, and acute : chronic workload ratio were calculated for analysis. Results: The season mean wITL was 10 381 6 4894 arbitrary units, mean session-RPE score was 5.0 6 1.6, and mean TQR score was 12.8 6 1.3. The gymnasts trained an average of 8.7 6 2.9 sessions per week, with a mean duration of 219 6 36 minutes. Each competitive period showed increased wITL compared with the previous period. Trainingload variables (wITL and session-RPE) and recovery were inversely correlated. Gymnasts were poorly recovered (TQR , 13) during 50.9% of the season (n ¼ 167 times), especially during competitive weeks. Spikes in load (acute : chronic workload ratio 1.5) occurred across 18.1% of the season (n ¼ 55 times). Conclusions: The training-load variables and recovery changed throughout a professional rhythmic gymnastics group season, mainly during competitive periods. The correct distribution of training load is critical to ensure that gymnasts are entering competitions in a recovered state.
