Greater postexercise hypotension response in low-load and high-volume resistance training versus high-load and low-volume resistance training

The post-exercise hypotension response (PEH) has been shown to be dependent on the load and volume of a resistance training (RT) prescription.
The aim of the present study was to compare the PEH between a low-load and high-volume and a high-load and low-volume RT session.
Ten young men with more than 2 years of RT experience participated in the study. All subjects were submitted to 5 and 15 repetition maximum tests, in counterbalanced order, for the following exercises: back squat, chest press, leg press and wide grip pulldown. Then, the subjects performed two protocols (P5 and P15) that consisted of three sets to volitional failure with 2-min rest intervals between sets and exercises. Blood pressure (BP) and heart rate (HR) were measured before and after 60 min following each session at 10-min time points.
Significantly greater total training volume was observed for all exercises in P15 (p < 0.05), whereas a significantly greater load was observed in P5 (p < 0.05). It was observed that the P15 session stimulated a greater PEH, with small to large effect sizes at various time points post-exercise, while the effect sizes for the P5 session were trivial in magnitude. Additionally, a significantly greater HR response was observed for the P15 versus the P5 during the recovery period.
Low-load and high-volume RT stimulated greater PEH compared to high-load and low-volume RT, suggesting the importance of RT volume in promoting healthy BP.
