The purpose of this study was to compare the effects of high, moderate and low intensity plyometric exercise on the post-exercise systolic and diastolic blood pressure and heart rate responses.
Ten healthy normotensive men (age, 21.1±0.9 years; height, 175.8±6 cm; and body mass, 69.1±13.6 kg) volunteered to participate in this study and were evaluated for three non-consecutive days in depth jump exercise from 20-cm box (low intensity [LI]), 40-cm box (moderate intensity [MI]) and 60-cm box (high intensity [HI]) for 5 sets of 20 repetitions. After each exercise session, systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were measured every 10 min for a period of 90 min.
No significant differences were observed among post-exercise SBP, DBP and HR when the protocols (LI, MI and HI) were compared. The LI and HI protocols showed greater reduction in SBP at 40(th)-70(th) min of post-exercise (9%), whereas the LI and MI protocols indicated greater reduction in DBP at 10(th)-50(th) min of post exercise (10%). In addition, the change in the DBP for HI was not significant and the increases in the HR were similar for all intensities.
It can be concluded that a plyometric exercise (PE) can reduce SBP and DBP post-exercise and therefore we can say that PE has significant effects for reducing BP and HR or post-exercise hypotension.
本研究旨在比较高、中、低强度增强式运动对运动后收缩压、舒张压及心率反应的影响。
10名健康的血压正常男性（年龄21.1±0.9岁；身高175.8±6厘米；体重69.1±13.6千克）自愿参与本研究，在三天内分别进行了不同强度的深度跳跃练习，即从20厘米高的箱子（低强度[LI]）、40厘米高的箱子（中等强度[MI]）和60厘米高的箱子（高强度[HI]）进行5组，每组20次跳跃。每次运动后，每隔10分钟测量一次收缩压（SBP）、舒张压（DBP）和心率（HR），共测量90分钟。
比较不同强度方案（LI、MI和HI）运动后的SBP、DBP和HR，未观察到显著差异。LI和HI方案在运动后40至70分钟时SBP下降幅度更大（约9%），而LI和MI方案在运动后10至50分钟时DBP下降幅度更大（约10%）。此外，HI方案的DBP变化不显著，所有强度下HR的增加相似。
可以得出结论，增强式运动（PE）可降低运动后的SBP和DBP，因此可以说PE对降低血压和心率或运动后低血压具有显著效果。
