To achieve the purpose of this study forty volleyball players were randomly selected from affiliated colleges of Bharathiar University, Coimbatore and their age ranged between 18 and 25 years. All the subjects were divided into two equal groups with 20 subjects each. Group-I underwent drill based high intensity interval training for a period of sixteen weeks and group-II acted as control who did not participate in any special training other than their regular routine. The fitness variables such as muscular strength and cardiorespiratory endurance were selected as dependent variables. Muscular strength was assessed by modified sit-ups and the unit of measurement in counts, cardio respiratory endurance was assessed by cooper 12min run and walk test and the unit of measurement in meters. Pre and post-test random group design was used for this study.
