More stimuli needed to build muscle in postmenopausal women: Study

Published in theย Journal of Applied Physiologyโ€‹ย and funded by global independent consulting firm Increnovo, theย randomized controlled, parallel-groupย trial examined the temporal responses of myofibrillar protein synthesis ratesย and anabolic signaling to resistance exercise alone or in combination with protein supplementation in postmenopausal women as compared to postabsorptive rates in younger women.

โ€œOur study showed that the muscle building effects of exercise and nutrition are impaired in menopausal women compared to young women,โ€ saidย Dr. Ralf Jaeger, managing member at Increnovo. โ€œAs a consequence, postmenopausal women need a greater stimulus to build muscle, either by working out harder or consuming greater amounts of protein.โ€

The nutritional supplement used in the study was provided in powdered form by Curves Japan Co. and contained whey protein isolate fortified with vitamins C, B1, B2, B3, B5, B6 and B12 and minerals calcium, magnesium, iron, zinc and potassium.ย 

Tackling postmenopausal muscleโ€‹

Age-related muscle mass loss, known as sarcopenia, is one of the more significant threats to the ability to remain healthy and function independently as people age. Decreased physical activity leads to muscle atrophy, loss of appetite resulting in nutrient deficiencies, and ultimately reduced quality of life and death, Dr. Jaeger noted.

In women, the hormonal changes in menopause have been associated with an acceleration ofย muscleย massย loss, as well as increased visceral fat and decreased bone density. Compared to aging males, postmenopausal females suffer from sarcopenia and musculoskeletal injuries at a greater rate.
