Effect of Different Resistance Exercise Methods on Post-Exercise Blood Pressure

The aim of the present study was to evaluate the post-exercise blood pressure (BP) responses to two different methods of resistance exercise (RE, traditional multiple set and tri-set). Young adult men (n = 30, 19.6 ± 0.7 years old; 76.0 ± 2.7 kg; 178.2 ± 6.7 cm; 90.5 ± 5.8 MBP) with six months of previous experience in RE were selected. The volunteers were randomly assigned into three groups (n = 10, each group): non-exercised control group (CON); multiple set group (MS); and a tri-set group (TRI). The TRI group performed three consecutive exercises (3 sets of 10 repetitions with 70% of 1RM and 1 minute of rest interval after the three exercises for the same muscle group) in the following order: bench press, cross-over and peck-deck and lat pull-down, seated cable row and barbell row. The multiple set group performed 3 sets of 10 repetitions for the same exercises, but with 1 minute rest interval between each set and exercise. After the exercise sessions and control situation, individuals remained seated for BP measure every 5 minutes up to 90 minutes. The repeated measures analysis of variance (ANOVA) (2 groups by three time points) was used, followed by post-hoc Bonferroni test, for p≤0.05. There were no significant alterations for systolic and diastolic blood pressure compared with the CON group and in the moments after exercise. Heart rate was increased after exercise for both exercised groups in all post-exercise measures compared with baseline. RE method (MS or TRI) exerted no influence on post-exercise blood pressure. Post-exercise induced hypotension may require the recruitment of larger muscle groups, such as those of the lower limbs.
