MUSCLE STRENGTH AND HYPERTROPHY FOLLOWING TWO RESISTANCE TRAINING PROTOCOLS IN EARLY POSTMENOPAUSAL WOMEN

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 testtwere 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.

Transdermal Estrogen

ContextWomen show an accelerated loss of muscle mass around menopause, possibly related to the decline in estrogen. Furthermore, the anabolic response to resistance exercise seems to be hampered in postmenopausal women.ObjectiveWe aimed to test the hypothesis that transdermal estrogen therapy (ET) amplifies the skeletal muscle response to resistance training in early postmenopausal women.DesignA double-blinded randomized controlled study.SettingDepartment of Public Health, Aarhus University, Denmark.ParticipantsThirty-one healthy, untrained postmenopausal women no more than 5 years past menopause.Intervention(s)Supervised resistance training with placebo (PLC, n = 16) or transdermal ET (n = 15) for 12 weeks.Main Outcome Measure(s)The primary outcome parameter was a cross-sectional area of quadriceps femoris measured by magnetic resonance imaging, and secondary parameters were fat-free mass (dual-energy X-ray absorptiometry), muscle strength, and functional tests.ResultsThe increase in muscle cross-sectional area was significantly greater in the ET group (7.9%) compared with the PLC group (3.9%) (p < 0.05). Similarly, the increase in whole-body fat-free mass was greater in the ET group (5.5%) than in the PLC group (2.9%) (p < 0.05). Handgrip strength increased in ET (p < 0.05) but did not change in the PLC group. Muscle strength parameters, jumping height, and finger strength were all improved after the training period with no difference between groups.ConclusionThe use of transdermal ET enhanced the increase in muscle mass in response to 12 weeks of progressive resistance training in early postmenopausal women.
