The Effects of Eight Weeks Resistance Training and Low Caloric Diet on Body Composition, Serum's Relaxin and Lipid Profiles of Postmenopausal Women

The onset of menopause is associated with the discontinuation of various hormones and women are susceptible to various diseases. The aim of this study was to investigate the effect of resistance training and low-calorie diet on body composition and serum's Relaxin & lipid profiles in postmenopausal women.

In this research 20 post-menopausal women were purposefully selected and randomly placed into experimental group (11 person by age 56.67 ± 2.87yr) and control group (9 person by age 56.67 ± 2.87yr. Both groups followed a low calorie diet. Experimental group training for 8 weeks, every week 2 days with the intensity of 20-30% 1RM In eight stations. The control group did their daily activities. The Relaxin, body composition and lipid profile in both groups was measured for effectiveness of the independent variable in postmenopausal women in 2-stage, one week before the start of the training program and 48 hours after the last training session in fasting state. The analysis covariance and dependent t test were used for data analysis at
significance level of p≤0.05.

The resistance training and low-calorie diet significantly decreased body weight and serum's relaxin & lipid profiles. But had no significant effect on abdominal obesity indices (Waist
Circumference, hip and WHR).

The post-menopausal women can use resistance training and lowcalorie diet for weight loss and improved serum's Relaxin and lipid profile and avoid the complications of
menopause.
