Abstract

The purpose of the study was to analyze the effect of eight weeks land based and sand based plyometric training on selected physical and physiological variables among inter collegiate level sportspersons pursuing their graduation under Kuvempu University. Subjects for the study were thirty (30) intercollegiate level sportspersons pursuing their graduation in Shivamogga. Their age ranged between 20 to 25 years. Purposive random sampling was observed in order to ascertain minimum levels of fitness of the sportspersons. Fifteen students each were placed randomly into plyometric training groups namely Land (N=15) and Sand (N=15) surfaces. In order to examine the efficacy of plyometric training on different surfaces following tests were conducted on all the subjects under the study. The subjects underwent these tests twice during the course of study i.e pre-test and post-test. The variables selected for the study were speed, dynamic strength, lower body explosiveness, agility, body composition and resting heart rate. Suitable standard tests were selected for assessing attributes. Paired sample ‘t’ test was used as a statistical technique apart from descriptive statistics. Within the limitations of the present investigation it is concluded that the speed aspect of physical fitness can be significantly enhanced through sand based plyometric training as compared to land based plyometric training.
