건강한 대상자에게 허혈성 전처치와 햄스트링 스트레칭, 복합적용이 운동능력에 미치는 즉각적인 효과비교

Abstract

Purpose: This study aimed to examine the effects of ischemic preconditioning (IPC), hamstring stretching, and complex approach on exercise ability and to identify the impact on the ability to recover after exercise. Methods: A total of 20 healthy adult males were included in this study. All subjects performed different interventions before exercise (nothing applied [CON], IPC, hamstring stretching, and IPC + hamstring stretching [Complex]), followed by cycling exercise, with a 5-min rest after exercise. Heart rate (HR), rate of perceived exertion (RPE), and oxygen saturation (Spo2) were measured during exercise and 5 min after exercise. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) was measured before exercise, immediately after exercise, and 5 min after exercise. Data analysis was performed using one-way repeated measures analysis of variance. Results: Exercise time was significantly different between Complex and CON and IPC conditions. RPE measured during exercise was significantly different between Complex and CON and IPC conditions. A significant difference in HR measured during exercise was observed between Complex and CON conditions. However, no significant difference in SBP, DBP, HR, Spo2, and RPE measured 5 min after exercise was observed between the conditions. Conclusion: Applying IPC and hamstring stretching together before exercise can be a particularly effective method for improving aerobic exercise capacity.
