Effects of Varied Modalities of Sports Specific Training on Speed and Explosive Power of Collegiate Male Handball Players

Sixty collegiate male handball players were randomly assigned from karnataka state elite collegiate handball players represented in inter collegiate tournaments, the aged range from 18 - 24(± 6 month) years.
Background Previous research has shown that collegiate male players can increase their speed and explosive power as a result of regular participation in a progressive sports specific training program. However, the most effective exercise prescription regarding the number of repetitions remains questionable.
Objective To compare the effects of a sports specific training-I and Sports Specific training-II on the development of speed and explosive power in collegiate male handball players. Intervention Sixty were divided in to three equal group. Experimental group I (n=20) under went sports specific training-I the players performed plyometric and heavy load resistance with skill practice (Experimental group II (n=20) under went sports specific training-II the players performed plyometric and moderate load resistance with skill practice and control group did not go any specific training. In 4 days session per week of sports specific training for 8 weeks, The control group did not practice any specific training. Sargent Vertical Jump test for measuring the explosive power and 50 meter dash for measuring the speed.
Results varied Sports specific training 50 meter dash test significantly increased speed in both training groups compared with that in the control subjects. Increases of 8.65 % and 6.80 %, respectively, for the plyometric and heavy load resistance with skill practice. Polymeric and moderate load groups resistance with skill practice were observed. Sargent vertical jump test significantly increased explosive power in both exercise groups compared with that in the control subjects, Increases of 14.99 % and 10.82 %, respectively, although gains resulting from high repetition-moderate load training (6.54 ± 0.43 repetitions) were significantly greater than those resulting from low repetition-heavy load training (6.71 ± .40 repetitions). On the speed exercise, only the plyometric and heavy load resistance with skill practice group made gains in 50 meter dash (8.65 %) and explosive power (14.99 %) that were significantly greater than gains in the control subjects. Conclusion These findings support the concept that speed and explosive power can be improved during the varied modalities of sports specific training on collegiate male handball players.
