Abstract :
AbstractAim: The aim of this study was to investigate the effect of eight weeks of resistance training and whey protein supplementation on female serum hyperlipidemia. Methods: The research method was semi-experimental. 18 overweight women aged 20 to 35 years and a body mass index of more than 25 were randomly selected and randomly divided into two experimental (8) and control (10) groups. Both groups practiced resistance training for eight weeks based on the principle of overload. During this time, the experimental group consumed 1.2 mg for per kilogram of body weight whey protein supplementation, per day, and the control group consumed the same amount of maltodextrin. Blood samples were taken before and after the period of eight weeks. Data were analyzed using an Kolmogram-Smirnov test, independent and dependent t test at a level α<0.5. Results: The results showed that resistance training and whey protein supplementation had a significant effect on LDL ‐ C, but trigliceride, total cholesterol, HDL ‐ C serum did not have a significant effect. The results obtained from the dependent t between pre-test and post-test in the experimental group were significant only in blood cholesterol and low-density lipoprotein, and there was no significant difference in other indicators. Conclusion: Whey supplementation and strength training improve body composition and fat profile, but more time (more than 12 weeks) is needed for significant changes.
