This study aimed to compare six weeks of weight training with HMB and creatine supplementation and two weeks of non-training on body composition and muscle function factors in male powerlifting athletes Thirty-two male athletes aged 21 to 30 years were randomly divided into four groups of 8 people creatine, HMB, HMB + Cr, and weight training. The training program was designed for 6 weeks and four sessions per week. The HMB group had 3 grams of the supplement on training days and 1 gram on non-training days, the creatine group on training days in 3 servings of 5 grams and 5 grams on non-training days, HMB + Cr group HMB supplement in 3 grams per day, and Creatine was consumed in the same way as the creatine group. During the two weeks of training, the HMB group received 1 gr of the supplement daily, the creatine group received 5 gr of the supplement, and the HMB + Cr group received 1 gr of the HMB supplement daily and 5 gr of the creatine supplement. A Two-way analysis of variance with repeated measures was used to test the hypotheses. Comparison between groups showed that there was not a significant difference in body fat percentage, lower body muscle strength, and muscle endurance between the four groups of weight training, creatine supplementation, HMB supplementation, and HMB + Cr supplementation in the post-test and two weeks of non-training. Also, the comparison between the groups showed that There was a significant difference in upper body muscle strength in the post-test, between the HMB + Cr group and the weight training group, the HMB + Cr group and the creatine group, the HMB + Cr group and the HMB group and Also in two weeks of non-training, between HMB + Cr group and weight training group, HMB + Cr group and creatine group, HMB + Cr group and HMB group, also comparison between groups showed that in two weeks of non-training, there was a significant difference in lower body muscle endurance between the weight training group, and HMB, the weight training group and HMB + Cr. It seems that six weeks of weight training with a combination of HMB and creatine supplements and two weeks of non-training can lead to a reduction in body fat percentage and improved muscle function factors in male powerlifters.
