IMPACT OF ISOLATED AND COMBINED RESISTANCE TRAINING AND PLYOMETRIC TRAINING ON STRENGTH AND POWER OUTPUTS

"SHAFEEQ, V. A.; DHINU, M. R.; JACKSON, P.; SHINE SINGH, J. P. Impact of isolated and combined resistance training and plyometric training on strength and power outputs. Brazilian Journal of Biomotricity. v. 7, n. 2, p. 117-127, 2013.The present investigation intended to determine the impact of resistance training, plyometric training and combined resistance and plyometric training on strength and power out puts in young boys. Sixty physically active students, aged between 17-20 years (mean age +/-1.9 years) participated in the study and they were randomly assigned into four equal groups with fifteen subjects each. Group I was involved with resistance training, group II plyometric training , group III combined resistance and plyometric training and group IV acted as control group. The experimental groups underwent their respective experimental treatment for eight weeks, 3 days a week and one session per day. Control group was not exposed to any specific training apart from their regular activities. Leg strength, elastic strength and explosive power were taken as variables for this investigation. The pre and post tests were conducted one day before and after the experimental treatment. The collected data were treated with Analysis of Covariance and Scheffe’s test was applied as a post hoc test to determine which of the paired means differed significantly. The result of the study revealed that all the three trainings such as resistance training, plyometric training and combined resistance and plyometric training produced significant improvement on leg strength, elastic strength and explosive power (p < 0.05) as compared to control group. It was concluded that the combinatory training protocol produced greater impact than resistance and plyometric training given alone."
