ABSTRACT:
The purpose of the study was to find out the effect of intensive and extensive interval training on maximal oxygen uptake (Vo₂ max) among kho-kho players. To achieve the purpose of the study, thirty male Kho-Kho players studying varies department, Annamalai University, Chidambaram, Tamil Nadu, India, were randomly selected and divided into three groups of ten each. The age of the subjects, ranged from 18 to 25 years. This study consisted of two experimental variables intensive interval training and extensive interval training. The allotment of groups was done at random, thus Group-I underwent intensive interval training, Group-II underwent extensive interval training for three days per week for twelve weeks, Group-III acted as control. The selected dependent variable was maximal oxygen uptake (Vo₂ max) and was appraised using methods and instruments of scientific standards. The experimental groups underwent their respective training programme for three days a week for twelve weeks. To statistically analyse the changes on criterion variables, ‘ANCOVA’ and Scheffé S test were used. The analysis of data revealed significant improvement on selected criterion variables as a result of experimental treatments. while extensive interval training maximal oxygen uptake (Vo₂ max). These results suggest that interval training of varied intensity may be adopted according to the need of the player.
