EFFECT OF VARIED INTENSITY INTERVAL TRAINING ON SELECTED MOTOR FITNESS COMPONENTS AMONG HIGHER SECONDARY SCHOOL BOYS

The purpose of this study was to compare interval training programmes of different intensity on selected motor fitness components among college boys. For this purpose 45 college boys from karaikal, aged 18 to 21 years took part in the study. Subjects were randomly assigned to three groups of 15 each. Group-I underwent intensive interval training, group-II followed extensive interval training and group-III acted as control subjects. The training regimen lasted for eight weeks. The strength endurance, cardiorespiratory endurance and speed were selected as criterion variables, and they were assessed using standard tests and procedures, before and after the training regimen. Analysis of Covariance (ANCOVA) was used to determine the significant difference existing between pre and post test on selected criterion variables. The analysis of data revealed that both the experimental treatments had significant impact on chosen motor fitness components, however there was significant difference in the level of effectiveness of intensive and extensive interval training on cardio respiratory endurance and speed
