The effect of plyometric and speed training on kinetic energy and jumping performance of college level long jumpers

Abstract

Plyometric is a conditioning technique used to increase performance in sports that require explosive speed and power along with quick change of pace–stop-and go movement. Depth Jump is the most popular and most effective method for the development of explosiveness. It is also the most effective method for developing the reactive ability of your neuromuscular system. The investigator selected 60 long jumpers of college level boys who participated in the college and inter college competition as subjects. The age group of the subjects was 18 to 25 years. there were divided in to 3 equal groups. One group was designed as control group, Experimental group I, and Experimental group II. The groups were equated on the basis of the mean and standard deviation of long jump performance. Experimental group I was applied with speed training (Wind Sprint, Harness running, interval training) Experimental group II was applied with plyometric training (Depth jump, Bounding drill, Squat jumps). In order to find out the improvement in kinetic energy and long jumping performance. ANACOVA technique used as suggested by Clark and Clarke, of the F ration was significant the scheffes post hoc test was used to find out the paired mean difference. In analysis of Co-variance, the final means were adjusted for difference in initial means and the adjusted means were tested for significance.
