ABSTRACT:
Aim of the study is to find out the effects of low vs moderate intensity physical activity on selected physical variables among sedentary individuals. To achieve the purpose of the study, 36 sedentary students were selected from Scott Christian College, Nagercoil, Tamil Nadu, India and their age ranged 18 to 22 years. The selected subjects were randomly assigned into three groups of (n=12) each, such as experimental and control groups. Group I (n=12) underwent low intensity physical activity training, Group II (n=12) underwent moderate intensity physical activity training and Group III (n=12) acted as control group for a duration of 12 weeks and the number of sessions per week was confined to three alternative days. Speed and explosive power were selected as dependent variables. To measure the dependent variable 50 metre run and Vertical jump test were used. Pre and post tests randomized control group design was used as experimental design. The collected data from the subjects were analysed with paired sample t-test and analysis of covariance (ANCOVA) at.05 level of significance. It was concluded that the speed and explosive power had significant improved due to low and moderate intensity physical activity and moderate intensity physical activity group had better performance than low intensity physical activity on speed and explosive power.
