چکیده مقاله :
In this study, concentrations of some blood biochemical factors in male powerlifting athletes were compared through 6 weeks of weight training with combined beta-hydroxy-beta-methylbutyrate (HMB) and creatinine (Cr) supplements and 2 weeks of non-training. Thirty-two male athletes aged 21-30 years were randomly divided into four groups of eight individuals: Cr, HMB, HMB + Cr, and weight training. The training program was designed for 6 weeks and four sessions per week. The HMB group consumed 3 g of the supplement on training days and 1g on non-training days, the Cr group consumed three servings of 5 g on training days and 5 g on non-training days, and the HMB +Cr group consumed the same amount of HMB and Cr supplements as the HMB and Cr groups. During 2 weeks of non-training, the HMB, Cr, and HMB + Cr groups received daily 1 g, 5 g, and 1 g of HMB + 5 g of Cr, respectively. The hypotheses were tested by two-way repeated-measures analysis of variance (ANOVA). Results: There were no significant differences in Cholesterol (Chol.), Triglyceride (TG), and Low-Density Lipoprotein (LDL) levels after the post-test and 2 weeks of non-training. There were significant differences in High-Density Lipoprotein (HDL) in post-test between groups of weight training and HMB (p = 0.000), weight training and HMB + Cr (p = 0.002), Cr and HMB (p = 0.000), and Cr and HMB + Cr (P = 0.001). The weight training and HMB (p = 0.000), weight training and HMB + Cr (p = 0.003), Cr and HMB (p 0.000) =), and Cr and HMB + Cr groups (p = 0.001) were significantly different in 2 weeks of non-training. Conclusion: Six-week weight training with combined HMB and Cr supplement and 2 weeks of non-training can significantly change the concentrations of some blood biochemical factors in male powerlifting athletes.
