Efeitos agudos do body weight training na frequência cardíaca

Objective: To analyze the acute effects of body weight training on heart rate. Methods: Twenty volunteers (10 men and 10 women), aged between 21 and 33 years (27±6), practicing physical exercise regularly for at least six months participated in this study. All participants performed a 20-minute body weight training session, performed in circuit format without interval. For the statistical analysis, we used SPSS software (version 22.0) and the level of significance was 5%. Results: The initial rest phase presented values significantly (p < 0.05) lower (77 ± 6) than that found in the other instants; (p < 0.05) higher values (97 ± 18) than the initial rest phase, but smaller (p < 0.05) in relation to the other phases; the main phase values significantly (p < 0.05) higher (152 ± 6) in relation to the other phases; the phase of return to calm values significantly (p < 0.05) smaller (129 ± 5) than the main phase, but larger (p < 0.05) in relation to the other phases; and the final resting phase (129 ± 5) identical to phase behavior returns to calm. Conclusion: The practice of body weight training is a means of training predominantly in the aerobic zone (76% to 81% HRmax). Key-words: resistance training, exercise, gymnastics, heart rate. 179 Revista Brasileira de Fisiologia do Exercício 2018;17(3):178-184
