Changes of the maximal muscle torque in women training Power Yoga (Astanga Vinyasa)

Abstract

Purpose. The aim of the study was to examine the changes of the maximal muscle torque in females during a six-month Power Yoga (Astanga Vinyasa) training. It was assumed that Power Yoga training caused changes of the maximal muscle torque in females during six months, but the topography of all muscle groups did not follow these changes. Basic procedures. Twelve untrained female subjects took part in the study. They practiced Power Yoga twice a week for six months. Muscle torque measurements in static conditions were performed on two dates: before the commencement of Power Yoga training and after its completion. Ten muscle groups were studied: flexors and extensors of the trunk, as well as flexors and extensors of the shoulder, elbow, hip and knee. Main findings. The differences between muscle torque values for flexors and extensors of the shoulder, elbow and hip, as well as flexors of the knee on the right side of the body were statistically significant between the 1st and 2nd measurement. On the left side of the body, only the muscle torque of the elbow extensors increased significantly. For flexors and extensors of the trunk, the changes were not significant. No changes of the flexors–extensors ratio for the shoulder, elbow, hip, knee joints and trunk were observed during the six months of training, with the exception of left shoulder muscles and right knee muscles. Conclusions. Power Yoga training caused changes of the maximal muscle torque in females after six months, but the changes in the muscle topography were also significant.
