Abstract:
The purpose of this study was to find out influence of moderate intensity interval training on selected physical fitness variables among school boys. To achieve the purpose of this study thirty (n=30) school boys were selected from Chennai, Tamil Nadu. The selected subject’s age ranged between 14 to 17 years. Further they were classified at random in two equal groups of 15 (n=15) subjects each. Group - I (Experimental Group) underwent high interval training for thrice in a week of six weeks, and each section lasted 45minutes and the Group – II - acted as a control group (CG) they did not participate in any kind of training programme apart from the daily activities. The selected physical fitness variables such as speed and cardio respiratory endurance were measured by 50m and 12min run and walk test. The collected data were analysed statistically through analyse of covariance (ANCOVA) to find the significance difference. The results of the study showed that selected physical fitness variables were significantly improved due to interval training of school boys.
