Effect of Resistance Training with Whey Protein Isolates and Whey Protein Concentrate Supplementation on Muscular Power and Muscular Strength among Sub Junior National Weightlifter

Abstract:

The purpose of the study was to find out the effect of resistance training with Whey Protein Isolates and Whey Protein Concentrate Supplementation on Muscular power and Muscular strength among Sub Junior National Weightlifter. For this purpose, thirty weight lifters were selected at random from the Army sports institute, Pune. Their age ranged between 12 and 16 years. The selected thirty weight lifters were randomly assigned into three groups namely, resistance training with whey protein isolates supplement group (RTWPIG), resistance training with whey protein concentrate group (RTWPCG) and placebo group (PG) each consisting of ten subjects. The subjects were given resistance training with whey protein supplementation for a period of twelve weeks. The subjects were tested Muscular power and Muscular strength through using medicine ball throw and 1RM. After the experimental period, the collected data was analysed by using analysis of covariance. The level of significance was fixed at 0.05 level. The results showed that the twelve weeks of resistance training with varied nutritional supplementation had a significant improvement on the Muscular power and Muscular strength. Resistance training has been shown to improve not only the force production of a muscle, but also muscular power and strength. In addition to intense training, a proper nutrition program is also responsible for maximizing the performance of strength and power athletes.
