The purpose of the study was to examine the effect of combination of isotonic and isometric training with asanas practices on selected bio motor variables of adolescent boys. To achieve the purpose of the present study, thirty school boys from Zillaparishad high school Jajapur, Mahaboob Nagar district, Telangana state were selected as subjects at random and their age ranged from 12 to 14 years. The study was formulated as a true random group design, consisting of a pre-test and post-test. The subjects were randomly assigned to two equal groups of fifteen each and named as Group ‘A’ and Group ‘B‘. Group ‘A’ underwent Isotonic and Isometric Exercises combined with Asanas Practices and Group ‘B’ underwent no training. The experimental group had undergone training for six weeks on alternate days. The variables namely speed and flexibility the data were subjected to “t” test and analysis of covariance technique. It was found that the Isotonic and Isometric Exercises combined with Asanas Practices group showed significant improvement on speed and flexibility among school boys. It was also found that the experimental group had shown significant improvement on speed and flexibility than the control group.
