Modulating infl uence of lills on energy exchange of CNS at the execution of specifi c physical load of sportsmen-players

Abstract

Purpose. To assess effects of low-level laser irradiation ( LLLI ) at the energetic activity of cortical cells under physical loading in athletes so as to correct their functional state. Materials and methods. High-class athletes, representing game sports (football – Smolensk Football Club – 24 subjects, ice-hockey club «Slavutich» – 31 subject). Equipment: hardware and software complex for topographic mapping of brain electrical activity «Neuro-KM»; laser therapeutic apparatuses «Uzor-3K» and «Uzor-3KS». Results. Low-level laser irradiation under specifi c physical loading caused a reliable overall group decrease in the level of constant potentials in the lower-frontal region as compared with the effect of isolated physical loading leading to a signifi cant increase of this parameter. In the remaining regions, one can only trace a tendency of the studied parameter to move toward the initial level as a reaction to LLLI. Conclusion. Low-level laser light has a positive effect at the central nervous system which corrects functional state of athletes during their trainings; and the level of constant potentials in this case is an informative indicator.
