Abstract
The purpose of the study was to find out the effect of plyometric training on bio-motor abilities such as speed and leg strength among college athletes. To achieve this, thirty male athletes studying in the Bharath Niketan College of Engineering, Andipatti, Tamilnadu, in the age group of 18 to 25 years were selected as subjects at random with their consent. The selected subjects were divided into two equal groups of fifteen subjects each namely plyometric training group and control group. The selected criterion variables were assessed using standards tests and procedures, before and after training regimen. Speed and leg strength were tested before [pre] and after [post] the training program for both experimental and control group by using 50 meters dash and leg llft with dynamometer respectively. The selected subjects had undergone the plyometric training for eight weeks, with three days per week in alternate days..after 10 to 15 minutes of warm-up the subjects underwent their respective plyometric training programmed and the subjects performed 6to 12 repetitions of plyometric exercises namely hopping, hurdles exercises, depth jumps, medicine ball throws, with a recovery distance of 20 to 40 meters or one to three minutes between repetitions. The control group did not participate in any specialized training during the period of study. The result of the study indicates that the plyometric training group had significantly improved the selected dependent variables namely speed and leg strength.
