Impact of occlusion manoeuvre on arterial blood flow intensity at onset of exercise

Abstract

We tested the hypothesis that it would be possible to decrease the so called “blood debt” which appears at the beginning of the intensive work, and in this way to increase muscle working capacity. Fourteen middle distance runners participated in the study. e aim of this study.We conducted the following studies trying to reach the stated objectives: 1 –  influence of the short term occlusion on the dynamics of the arterial circulation in calf muscles; II – influence of  the short term preliminary occlusion on the  working capacity of the calf  muscles; III – influence of a short term preliminary occlusion on the dynamics of the arterial blood flow at onset of calf exercise. The results have shown that a exposure of short term preliminary occlusion decreased so called “blood debt” which appears at the beginning of the intensive work, and in the same way increased muscle working capacity. Our findings demonstrate that a local response, i.e. vasodilation in skeletal muscles plays an important role in the development of functional hyperaemia at the onset of exercise. In conclusion, a short term preliminary occlusion improves muscle blood flow and as a result local muscle working capacity is improved.
