PLYOMETRICS: An Integrated Eccentric–Concentric Exercise Regime for Augmentation of Sports Performance in Young Adolescents

AbstractBackground:The type of exercise training regimen has a significant impact on athletic performance. Plyometric exercise primarily consists of an eccentric phase of ‘stretching’ the muscle which is quickly followed by a strong isometric contraction in the later phase. On the other hand, aerobic exercise enhances stamina and cardiovascular capacity.Objectives:The aim of the current study is to investigate the effects of plyometric training on the endurance and agility of school children.Materials and Methods:This quasi-experimental pilot study was conducted at Kendriya Vidyalaya in Pushp Vihar, New Delhi. Convenience sampling was used to recruit 50 school kids who were randomly split into two groups using Chit Method: plyometric and aerobics groups. The plyometric training group exercised two times a week for a minimum of 6 weeks as part of the programme and there were no plyometric exercises used in the aerobics group. Subjects must complete the agility (t test) and endurance preparatory tests (beep test). Posttests were administered after the intervention was complete.Results:Independent and paired t test revealed a significant effect P = 0.001 for the t test agility measure and endurance beep test measure.Conclusions:When compared to the aerobics group, the plyometric training group showed faster posttest times for the agility tests and showcased better VO2 max values for the endurance beep test.
