Effects of resistance training intensity, volume, and session format on the postexercise hypotensive response.

The effect of resistance exercise (RE) on the postexercise systolic and diastolic blood pressure (SBP and DBP) response in young men was investigated. Group 1 (G1) and group 2 (G2) performed three 6 repetition maximum (6RM) sets in a set repetition format for 5 and 6 exercises, respectively. G1 and G2 also performed a circuit and set repetition format session, respectively, using 50% of the 6RM for 3 sets of 12 repetitions (12-repetition protocol). SBP and DBP were determined before and up to 60 minutes postexercise. G1's postexercise SBP demonstrated a significant decrease from its preexercise SBP, lasting 50 minutes after both RE sessions. G2's postexercise SBP demonstrated a significant difference from its preexercise SBP after the 6RM and 12-repetition protocol, lasting 60 and 40 minutes, respectively. The only significant difference in the DBP from rest was at 10 minutes postexercise for G2 after the 12-repetition-per-set protocol. In summary, results indicate that RE intensity affects the duration, but not the magnitude, of the postexercise hypotensive response.
