Comparação entre os efeitos de diferentes protocolos de treinamento resistido sobre parâmetros cardiovasculares clínicos e ambulatoriais de idosos hipertensos

Introduction: Resistance training (RT) promotes numerous musculoskeletal and functional benefits and is recommended for elderly hypertensive subjects. The effects of RT with blood flow restriction (BFR) have been little investigated in this population. Objective: To compare the effects of RT recommended by the Brazilian Guidelines for Arterial Hypertension and RT with RFS on clinical and ambulatory cardiovascular variables of elderly hypertensive subjects. Methodology: Hypertensive elderly subjects were randomly divided into two experimental groups: Without RFS (N=14) and With RFS (N=13). The groups underwent an intervention period (10 weeks of RT, 2 sessions/week, 4 exercises performed unilaterally, 3 sets until moderate fatigue, with a 90s interval between sets). The Without RFS Group performed RT at an intensity of 50% of 1RM. The With RFS Group performed RT at an intensity of 30% of 1RM and with cuffs inflated to 70% of the total blood flow occlusion pressure. Before and after the intervention period, the volunteers underwent assessment of blood pressure and heart rate in clinical and ambulatory conditions. Results: Compared to pre-intervention values, none of the RT types promoted clinical and ambulatory cardiovascular changes (P>0.05). No significant differences were observed between the two experimental groups (P>0.05). Conclusions: It is concluded that none of the intervention types promoted clinical and ambulatory cardiovascular changes, so there was no difference between the effects of RT recommended by the Brazilian Guidelines for Arterial Hypertension and RT with RFS in elderly hypertensive subjects.
