Abstract:

Introduction: Low intensity strength training associated with blood flow restriction (STBFR) may be an effective alternative for individuals seeking neuromuscular adaptations similar to high intensity strength training (ST). Purpose: To compare hemodynamic responses between conventional strength training and strength training with blood flow restriction. Methods: Six individuals (26.0 ± 3.7 years, 70.3 ± 15.0 kg, 1.71 ± 0.10 m) underwent two strength training sessions at least 48 hours apart: ST = 3 sets of 10 repetitions at 80% of 1-RM predicted with 1 minute and 30 seconds of rest among sets; STBFR = 1 set of 30 repetitions plus 3 sets of 15 repetitions at 30% of 1-RM predicted associated with 80% of the systolic blood pressure of the exercised limb with 30 seconds of rest among sets. In both sessions, heart rate, blood pressure and double product were monitored. For data analysis, two-way ANOVA was used for repeated measures with Sidak post hoc with a significance level of 5%. Results: There was time effect for heart rate (p < 0.001), systolic blood pressure (p < 0.001), mean blood pressure (p < 0.05) and double product (p < 0.001), without difference between groups ST and STBFR. Conclusion: We concluded that both strength training sessions (ST and STBFR) presented similar behavior in relation to hemodynamic responses.
