Abstract

The aim of the work was to study the effect of laser exposure on the morphometric parameters of myosatellitocytes and myocytes during swimming training. Material and methods. The experiment was performed on 18 rats, divided into groups: 1) control, 2) swimming training 3) swimming training with infrared laser action on the muscles of the hind limbs. Samples of the biceps femoris were fixed with formalin and histological sections were prepared. A morphometric analysis of the digital image of objects was carried out. Results. Swimming training led to an increase in the number of myosatellites, the area of the nuclei of myosatellites and myocytes, and the cross-section of muscle fibers. Laser effect on muscle tissue during training contributed to a significantly greater increase in the studied parameters and an increase in the number of myocytes. Findings. The laser effect during swimming training stimulates the proliferative capabilities of muscle tissue.
