Article Synopsis
- The study investigated the relationship between testosterone levels, muscle mass, and strength in pre-menopausal females undergoing a 12-week resistance training program, finding no link with total circulating testosterone.
- Bioavailable testosterone and the localization of androgen receptors (AR) in the nucleus were positively associated with muscle mass and strength, suggesting a unique role of these factors in muscle development for females.
- In vitro experiments indicated that high doses of testosterone increased muscle cell size without activating the previously assumed Akt/mTOR pathway, instead enhancing the nuclear presence of the AR.
Older adults are at increased risk of being bedridden and experiencing negative health outcomes including the loss of muscle tissue and functional capacity. We hypothesized that supplementing daily meals with a small quantity (3-4 g/meal) of leucine would partially preserve lean leg mass and function of older adults during bed rest. During a 7-day bed rest protocol, followed by 5 days of inpatient rehabilitation, healthy older men and women (67.
