Abstract
Ischemic preconditioning has shown to be an effective performance enhancer in endurance athletes and in power. lifters; however, there is a lack of information on how this intervention affects explosive athletes in their sport. This study will test the effects of IPC on explosive, athletic movements in 18 to 24-year-old college athletes. The study will also be conducted to discover how long the possible beneficial effects of IPC last. IPC is a process of occluding blood to a limb for a short amount of time followed by a reperfusion period, all prior to engaging in exercise. In this study, we will use 80% of the limb occlusion pressure for five minutes, with a 5- or 60-minute reperfusion period, prior to engaging in the exercise testing battery. A combination of activities that measure explosive athleticism include the 40-yard dash, 5-10-5 pro shuttle, vertical jump test, and broad jump test. Participants will be college athletes, and they will be randomly assigned to one of two groups — the directly after IPC group (5-minute gap between IPC and exercise tests) and the one-hour after IPC group (60 minutes between IPC and exercise tests). Regardless of group assignment, all participants will complete a control condition of no IPC before performing the exercise tests, and the change from the control to each of the intervention conditions will allow us to assess 1) if one or both time delays from the IPC protocol are effective at improving explosive exercise performance and 2) if onetime delay (five or 60 minutes) following IPC is more effective at improving performance. We will use dependent samples t-tests to compare changes in exercise test performance between the control and intervention groups and independent-samples t-tests to compare change from control to intervention between the two intervention groups.
