Although a few studies examined the effects of plyometric exercise on cardiovascular responses and symptoms of muscle damage, the data about the different types of plyometric exercise such as eccentric-based vs. concentric-based exercise is scarce. The purpose of the present investigation was to compare the effects of eccentric and concentric-based plyometric exercises on post-exercise systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR) and symptoms of muscle damage. Nineteen healthy men volunteered to participate in this study and were randomly assigned to two groups: Depth jump group (DJG; N=9; Eccentric) and Box jump group (BJG; N=10; Concentric). After plyometric exercise SBP, DBP and HR were measured every 10 min for a period of 90 min post-exercise. Also, muscle soreness, vertical jump and 10-m sprint were assessed at 24, 48, and 72 h post-exercise. There were no significant changes in SBP and DBP, and no significant differences between groups in SBP and DBP, whereas the DJG showed greater increases in HR when compared with BJG. Both the groups indicated significant differences in muscle soreness, vertical jump and 10-m sprint at 24, 48 and 72 h post-exercise without significant differences between them. The findings of this study demonstrated that there were no differences in SBP and DBP between groups and both groups showed increases in symptoms of muscle damage following plyometric exercise.
