ABSTRACT
The objective of the study was to assess the outcome of carbohydrate loading dietary strategy on resistance exercise and muscle mass. In this prospective study, conducted at Dr DY Patil Gym and Fitness Center, Navi Mumbai (India), young healthy male resistance-trained individuals (18-25 years) were recruited randomly. The duration for entire study was three months in the year 2019. Participants were divided into two groups (n=30 each): carbohydrate loading group and control group. Participants in the carbohydrate loading group consumed carbohydrate loading diet protocol and designed exercise program for seven days. The control group consumed a regular diet with an exercise program. Resistance exercise (strength) and body circumference (muscle mass) measurements were recorded after seven days of respective assigned diet and exercise program. In the carbohydrate loading group, performance in resistance exercise was not significant from baseline to day seven (63.5±6.45 vs. 64.0±6.75 kg; p>0.05). Changes in the arm girth (p=0.3256), thigh girth (p=0.3256) and calf girth (p=0.1608) were also not significant in the carbohydrate loading group when compared from baseline to seven days. Therefore, the result indicates that the carbohydrate loading regimen had no enhanced effect on resistance exercise as well as muscle girth. This study results suggest that carbohydrate loading has no additional advantage in improving resistance exercise and muscle mass in resistance-trained individuals.
