This study was designed to determine the effects of resistance training (RT) on prevention of sarcopenia in elderly women. 20 postmenopausal women aged over 50 were randomly divided into two groups of control (C) and experimental (RT). The subjects performed the resistance training three times a week for 12 weeks. The charts for the Thera-Band resistance colors sequence were used to determine the force produced by Thera-Band. skinfold thickness of the two groups was measured by a caliper and BF%, BMI and FFM were determined. Independent and paired t tests were used to analyze the data. The results showed significant difference in BMI and caloric intake in both groups. There was a significant difference in 1-RM and relative strength in RT group. BMI, %BF, skin fold thickness and FFM significantly decreased in RT and increased in C. There were significant differences between RT and C groups in skin fold thickness of triceps and %BF. In conclusion, resistance training with Thera-Band in elderly women may contribute to prevent disability induced by sarcopenia.
