Background: The balance in the upright position becomes considerably more complex due to different changes, such as the decrease in the size of the support base and changes in the center of pressure (COP). However, there are no studies that relate differences between sex and ischemic preconditioning protocol (IPC).
Objective: The purpose of this investigation was to compare differences in plantar pressure distribution and center of pressure between males and females practitioners of resistance exercise.
Methods: All participants (male, n=16; female, n=15) were practitioners of resistance exercise and underwent four tests in the baropodometry platform before and after IPC protocol in static and dynamic conditions. The IPC protocol consists of 4 × 5-min occlusion 220 mmHg/reperfusion 0 mmHg in thighs.
Results: The forefoot and hindfoot pressures showed significant difference (p<0.001) between before vs. after intervention in the right plantar surface area in males. On the other hand, hindfoot pressures were significantly higher that forefoot before vs. after intervention in the right plantar surface area in females (p<0.01). Student’s t-test showed that during dynamic conditions occurred decrease significant (p<0.02) before vs. after intervention in the left plantar surface area maximal pressure in males. In contrast, the right plantar surface area mean pressure showed significant difference (p<0.01) during static conditions in males. The COP showed decrease significant (p<0.03) after intervention only left side in males.
Conclusion: This study showed decrease of the plantar surface area pressure and COP in dynamic and static conditions in the males after IPC protocol.
