Ischemic Preconditioning Contribute to Improving the Static and Dynamic Stability of Male Trained

Q: What was the study objective regarding ischemic preconditioning protocol (IPC)?

To compare differences in plantar pressure distribution and center of pressure between males and females who practice resistance exercise.

Q: How was the IPC protocol administered in this study?

Participants underwent IPC consisting of 4×5-minute thigh occlusion at 220 mmHg followed by reperfusion at 0 mmHg.

Q: What were the main findings about plantar pressure and COP after IPC?

In males, plantar surface area pressure and COP decreased in both dynamic and static conditions after IPC; changes also differed by sex and by forefoot/hindfoot measures.

Background: Balance in the upright position becomes more complex with changes such as a smaller support base and shifts in the center of pressure (COP), and evidence comparing sex differences under ischemic preconditioning protocol (IPC) is lacking. Objective: Compare plantar pressure distribution and COP between males and females resistance-exercise practitioners. Methods: Baropodometry platform tests (static and dynamic) before and after IPC; IPC was 4×5-min thigh occlusion (220 mmHg) with reperfusion (0 mmHg). Results: Significant plantar pressure and COP changes occurred in a sex- and condition-dependent manner. Conclusion: IPC reduced plantar pressure area and COP in males under both static and dynamic conditions.

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.

Hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischemia (e.g., blood flow restriction), thus, promote greater shear stress against blood vessel walls on restoration of blood flow that occurs with release of occlusive pressure that contribute with a vasodilatation by increase in blood flow to a tissue due to the presence of metabolites (adenosine, prostaglandins, and oxide nitric) and myogenic effects [1-3] .
The ischemic preconditioning (IPC) protocol consists of alternating periods of blood flow occlusion/reperfusion of limbs through a pneumatic tourniquet applied around the upper thighs or arms regions. This idea was based on clinical | experimental research, where the effects of IPC protocol were related to an intervention that also affects organs other than those where it is applied [1,2] . Since IPC had shown positive protection effects on myocardial cells for events of limited blood
