Abstract:
The present study was conducted with an aim to investigate the effect of leucine supplementation in muscle growth of gym goers. 15 healthy male gym-goers ingested with 3 g/d of leucine and 15 healthy male gym goers were considered as test and placebo group, respectively. Their daily dietary intake was assessed and was told to stay on same diet and exercise routine till the completion of study period. Anthropometric measurements, body measurements and body composition were assessed on the initial day and at the end of the study period. A significant difference (p≤0.01) was observed between pre and post value of supplemented group for WHR. Medium effect size (0.7) for WHR between two groups was observed significantly which indicates that the change was moderate between the groups after supplementation. Independent t- test showed small value of effect size for visceral fat (0.3) and medium for bone mass (0.4) between two groups. These results states that 3 g/d of leucine supplementation for 45 days can enhance muscle growth and increases the strength performance of the gym persons.
