EFFECT F INFRARED LASER RADIATION AND AMINO ACID INTAKE ON THE VASCULAR BED ADAPTATION OF THE IN TERMUSCULAR CONNECTIVE TISSUE 158 TO PHYSICAL ACTIVITY

Abstract

The aim of the study was to analyze the effect of laser irradiation and branched chain amino acids (BCAAs) on the restructuring of the vascular component of m. biceps femoris during systematic swimming training. Material and methods. The experiment was conducted on 25 rats divided into 5 groups: 1) intact control, 2) dynamic control, 3) training with amino acid intake, 4) training with infrared laser exposure, 5) training with laser exposure and amino acid intake. Tissue samples of the biceps femoral muscle were fixed with formalin with further use of classical histological wiring. Morphometric analysis of the digital image of objects was carried out. Results. Exposure of infrared laser radiation, as well as the use of amino acids, contributes to a reliable increase in the area of the vascular bed relative to the area of connective tissue. When the studied factors were combined, statistically significant differences were found with isolated laser or amino acid exposure groups. Conclusions. The intake of amino acids and the use of laser radiation stimulates the increase of vascular bed area during the training cycle
