The Effect of Protein and Carbohydrate Consumption During 10-Week Strength Training on Maximal Strength and Body Composition

Abstract

In this study, it was aimed to examine the effect of protein and carbohydrate consumption on repetitive maximal strength and body composition during the 10-week strength training. The mean age and height of the groups are as follows; experimental group CAR: (n=10) 20.04 +/- 1.38 years, 173.44 +/- 4.62 cm, PR (n=10) 21.29 +/- 2.44 years, 177.24 +/- 4.22 cm and placebo group; PLA (n=10) 20.14 +/- 2.19 years, 174.15 +/- 5.12 cm in total and 30 inactive male individuals participated in the evaluation. The research was conducted as a single blind study. Scitec Isolate Whey Protein and Hardline Carbopure supplementation was given to the experimental groups under the researcher supervision for 10 weeks in appropriate for daily use type and dose. 0.75 g/kg protein was given to the PR group two hours before the training, 0.75 g/kg protein was given immediately after the training and totally 1.5 g/kg 500ml water and protein supplement was given on the days of training. In carbohydrate supplementation, carbohydrate supplements were applied as 3.0 g/kg two hours before the training and 3.0 g/kg immediately after the training, and a total of 6 g/kg 500m1 water on the days of training. In the research, synthetic colorant, which does not increase blood sugar, was given to the PLA group with 500m1 water in equal amounts to the given supplement. As a result; while the use of carbohydrate and protein supplements in the 10-week strength training performed 4 days a week provided positive improvements on body composition and 1MT, especially the use of protein provided more positive developments on fat percentage and lean body mass.
