Item 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 GattásObjective: 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.Item 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 GattásThe 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.
