Aim: The aim of this study is to evaluate the effects of resistance training and low calorie diet on body composition relaxin serum level of postmenopausal women.
Methods:In this research 20 post-menopausal women were purposefully selected and randomly divided into two groups (experimental group, n = 11 and control group = 9), the experimental group training for 8 weeks and every week 2 days with the intensity of 20-30% 1RM1, the control group continued their activities during a period of 2 month.
Body composition's factors by Inbody device and relaxin serum level with China's kit was measured in the fasting state, in two stages, one week before the start of the training program and 48 hours after the last training session in the eighth weeks was carried out.
The covariance and Pearson correlation test analysis were used for data analysis, level of significance was considered by SPSS 18 )p≤0/05.(
Results:The results showed that eight weeks of resistance training and low-calorie diet significantly reduced total cholesterol levels, triglycerides, LDL, relaxin and an increase in HDL values before the intervention.
Also body weight, fat mass, fat percent, lean body mass and BMI2 of the experimental group was significantly decreased, while the decrease of related indicators of abdominal obesity (waist size, hip and WHR) statistically is not significant, and also there were no significant relationship between relaxin serum levels and the components of body composition, and the relationship between relaxin serum levels and blood lipids in cholesterol serum level and LDL was significant.
Conclusion: Therefore decreased of relaxin serum levels induced by caloric restriction combined with resistance training can be effective in reducing the symptoms of menopause and affect them.
