Effects of recovery type in muscular oxygenation during squat exercise

Abstract

The objective of this research is to check the changes in muscle oxygenation of the rectus muscle during squat exercise depending on the recovery type. For this purpose, 11 men subjects well-trained were randomly assigned to three experimental groups: group performing passive recovery with 2 minutes rest (GC), a group that makes active recovery to stabilizing oxygen (GA), a group that performs passive recovery up stabilizing oxygen (GP). All the squat performed up to 90º to 65% of 1RM with 80% of the nature of the effort (CE) (4x10). The results show that the time of reoxygenation (TrecSmO2) was significantly lower in GA (77.94 + - 11.08) to GC (p <0.001). In the middle slopes of execution and reoxygenation the GA obtained the lowest and highest values respectively and significantly compared to GC (p <0.001). These two variables obtained an inversely proportional relationship with r = -0.9585 (p <0.001). These results show a better reoxygenation in the group that performed actively rest. an inversely proportional relationship between the inclinations of execution and recovery so that the more rapid and complete is the deoxygenation result shown slowest reoxygenation. In addition, oxygen saturation can be a factor of neuromuscular fatigue and control during strength training could facilitate training goals.
