Efficacy of Intensive and Extensive Interval Training on Selected Biomotor Abilities among Schoolboys

The present study was to compare the intensive and extensive interval training effects on selected biomotor abilities among schoolboys. For this purpose, forty-five male students of Okkoor Vellayan Chettiyar Higher Secondary School, Manamadurai, Sivagangai District, in the age group of 16 to 18 years were randomly selected as subjects. The selected subjects were assigned to one of the three groups namely; intensive interval training, extensive interval training and control group of fifteen subjects each. The selected dependent variables such as cardiorespiratory endurance and speed were appraised using methods and instruments of scientific standards. The experimental groups underwent their respective training programme for three days a week for eight 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 treatment. Where, intensive interval training amplified speed significantly, while extensive interval training enhanced cardiorespiratory endurance better. These results suggest that interval training of varied intensity may be adopted according to the need of the player
