AIMS: Adequate physical fitness contributes to the prevention of obesity and improvement of quality of life, and hormones play an important metabolic role in this regard. Obese individuals often hesitate when choosing the type of exercise for weight loss and health improvement. Therefore, the present study aimed to investigate the effect of twelve weeks of strength and plyometric training on IGF-1, IGFBP-3, and the inflammatory marker IL-6 in inactive obese men.
MATERIALS AND METHODS: This was a semi-experimental study with a pretest–posttest design, a control group, and random allocation. The statistical population consisted of 60 inactive obese men with a mean age of 28.23±1.75 years with a mean body mass index of 32.11±1.32, who were randomly divided into three groups of 20: strength training, plyometric training, and control. The training groups performed a conventional training program under the supervision of the researchers for 12 weeks, three sessions per week. Blood samples were collected 24 hours before the start of training and 24 hours after the last session. Normality of data distribution was assessed using the Shapiro–Wilk test, and changes were analyzed using mixed analysis of variance and t-test in SPSS26 (p<0.05).
FINDINGS: Plyometric training significantly increased IGF-1 and IGFBP-3 compared with the control group (p<0.05). Strength training significantly increased IL-6 and IGFBP-3 compared with the control group (p<0.05), whereas plyometric training had no significant effect on IL-6.
CONCLUSION: Given the nature of the exercises, plyometric training had a more favorable effect on growth hormone–related factors; since it did not significantly affect IL-6, these exercises can be appropriately and regularly incorporated into the exercise program of inactive obese men to improve health indicators.
