Concurrent treadmill running and strength exercise: acute effects of execution order on post-exercise hypotension

Abstract

The study analyzed systolic (SBP) and diastolic (DBP) blood pressure after two exercise bouts of concurrent exercise performed in a different order [aerobic-strength (AS), and strength-aerobic (SA)]. Fifteen normotensive subjects were submitted to two exercise bouts performed in different days in the following order: AS and SA. SBP and DBP were measured before and at each 15 min over a 60 min period of post-exercise recovery. Post-exercise hypotension (PEH) was found in SBP at the 30th (-7.4 mmHg), 45th (-12.14 mmHg) and 60th min (-15.14 mmHg) after AS when compared to rest. On SA, PEH was only observed at the 60th min (-8.34 mmHg) of recovery. The analysis of differences for SBP and DBP between both sessions showed greater PEH at the 15th, 45th, and 60th min in SBP; and at the 45th min in DBP after AS when compared to SA. Thus, performing aerobic before strength exercise elicited a higher PEH in young adults.
