Using of Paired Pulses of Light to Assess the Operability of Physical Training and Sports

Abstract

Itwasdevelopedamethodofevaluationofindividualefficiencyduringphysicaltrainingandsports, allowing to increase the accuracy of its diagnosis. The method is based on determining the time of using the pair of excitation light pulses indicative of the speed of excitation in the central nervous system. It was described the results of evaluation of physical performance of athletes aged 20 to 22 years, specializing in cyclic sports: long-distance runners and skiers. Qualification of testee is I discharge and candidates master of sports. Probationers were pre-trained in a certain threshold pulse interval (PI) , in which two pulses in a pair merge into one. When bicycle exercise load equal to 75% of maximal oxygen consumption due, subject periodically determines the threshold PI. According to the obtained values of the threshold PI plotted in the coordinates of its dynamics «the threshold PI - the testing time». Testing was repeated after two days of rest to the load increased by 50 W until the threshold PI dynamics graph will have a downward trend.The level of physical performance is determined by the previous graph threshold PS having a «plateau», the volume of work performed by formula: ? = W·t ,whereW – load power, W; t – testing time, sec.
