Effectsof aerobic and resistance trainings on relation between blood biochemical parameters and body compositionwith bone turnover markers in overweight men

Abstract

Introdution: The cells rolled in the formation of bone, regulated glucose metabolism, and increased insulin secretion from pancreatic beta cells and modulated the insulin resistance. Therefore, the present study aimed to study the effects of aerobic and resistance exercises on relation between blood biochemical parameters and body composition with bone turnover markers in overweight men.

Method: In this quasi-experimental study, a total of 36 overweight, young healthy men (age range28-35 years) were randomly assigned to the control (n=14), aerobic exercise (n=11) and resistance exercise (n=11) groups. In the aerobic exercise group, excercisetraining was performedfor 8weeks, three sessions per week (at 55-85% of HRR), and in the resistance exercise group,exercise training was perfprmed in 8weeks for three sessions per week(at 55-75% of 1RM). Body composition and blood samples were assessed from fasting blood samples before and after the 8-week exercise programme. Data wereanalyzed by t-test and ANOVA by SPSS ver.25 Software.

Results: Paired t-test and one-way ANOVA showed that aerobic and resistance training cause the reduction of body composition (P <0.05), increasing the osteocalcin (P = 0.001 and P <0.001) as well as a significant decrease in blood biochemical parameters (P <0.05). Also, Pearson correlation showed that there was no correlation between osteocalcin and blood biochemical parameters and body composition (P <0.05).

Conclusion: The results of this study showed that 8 -week exercise trainings increase osteocalcin levels, which is associated with a decrease in body weight and body fat percentage, particularly lipid profiles. However, despite the differences in mean, there was no statistically significant difference between aerobic and resistance training.
