Abstract EN
Objective.
To investigate the independent and additive effects of resistance training (RT) and soy isoflavone (ISO) on body composition in postmenopausal women (PW).
Method.
This study used a placebo-controlled, double-blind (soy), randomized (ISO versus placebo) × (RT versus No RT) design.
A total of 80 PW, aged 45–70 years, were randomly (71 completed 9-months intervention): RT + ISO (n=15), No RT + ISO (n=20), RT + placebo (n=18), and No RT + placebo (n=18).
ISO received 100 mg a day of isoflavone; and to RT attended supervised resistance training sessions.
At baseline and 9-months, fat and muscle mass were estimated by DXA.
ANOVA and test t were used.
Results.
RT groups showed significantly increased muscle strength (35.2%) and muscle mass (1.4%).
Exercising attenuated gains in fat trunk and % body fat (P<.05).
Significant decreases in muscle mass (−1.8%) and increases in fat mass of the whole-body (1.6%) and trunk (9.7%) was found in no-RT groups (P<.05).
In ISO groups, there were no differences in body composition and muscle strength.
ISO and RT had no additive effects.
Conclusion.
In PW: RT improved muscle mass and strength and attenuated gain of fat mass; ISO did not alter body composition and muscle strength; there were no additive effects of RT and ISO.
