Effects of circadian rhythm on selected factors related to performance of swimmers and Sprinters

Abstract

The purpose of the study was to find out the effects of circadian rhythm on selected factors related to sports performance of sprinters and swimmers To achieve the purpose of the study 15 male sprinters were selected from the Manonmaniam Sundaranar University Tirunelveli and 15 male swimmers were selected from the Anna University of Technology Tirunelveli randomly The age of the selected subjects ranged from 18 to 24 years Speed flexibility anaerobic power resting pulse rate skin temperature and total mood disturbance were selected as criterion variables The experimental design used was static group factorial design The first factor consisted of sports as sprinters and swimmers second factor consisted of circadian variation measured at six different times of the day Two factor analysis of variance with second factor repeated measure was used to find out the influence of each of the factor independently and also their combined influence on each of the selected variables In all the cases level of significance was fixed There was a significant variation in Circadian Rhythm between sprinters and swimmers on the selected variables such as speed anaerobic power flexibility skin temperature and total mood disturbance among different times of the day In all the selected variables it was found that the performance a suitable time for peak and highest level achievement newline
