Background and Aim: As age increases, problems related to decrease of muscle mass and strength, so-called sarcopenia, increase as well. The aim of this study was to determine the effect of eight weeks of resistance training and Leucine supplements on muscle mass in elderly men with sarcopenia.
Material and Method: A total of 40 elderly men residing in the elderly welfare center were randomly divided into four groups including: resistance training with Leucine supplement, resistance training, Leucine supplement, and control. Resistance training was performed eight weeks with %35-70 of one repetition maximum intensity for 20-45 minutes. Leucine supplement group consumed three grams of Leucine in each meal. One day before starting the protocol and 72 hours after the last training session, muscle mass, hand grip strength, and gait speed were measured. Two-way analysis of variance repeated measure was used to analyze within- and between-group changes. Bonferroni post hoc test was used to determine the differences among groups.
Results: Muscle mass increased significantly after eight weeks of resistance training compared to the control group (p=0.02). There was a significant increase in muscle strength in the resistance training and supplement group compared to the control group (p=0.001). There was also a significant difference in gait speed between the resistance training group and the control group (p=0.003).
Conclusion: Eight weeks of resistance training resulted in increased protein synthesis and muscle strength in elderly men with sarcopenia. Resistance training can be an effective way to prevent or reduce sarcopenia in the elderly.
