Maintaining a regular workout routine can help you look and feel great—but did you know that exercise also helps maintain your muscles and bones? People who are unable to engage in physical activity experience weakening of the muscles and bones, a condition known as locomotor frailty. Recently, researchers in Japan have identified a new drug that may aid in the treatment of locomotor frailty by inducing similar effects as exercise.
Physical inactivity can result in a weakening of the muscles (known as sarcopenia) and bones (known as osteoporosis). Exercise dispels these frailties, increasing muscle strength and promoting bone formation while suppressing bone resorption. However, exercise therapy cannot be applied to all the clinical cases. Drug therapy may be helpful in treating sarcopenia and osteoporosis, especially when the patients have cerebrovascular disease, dementia or when they have already become bedridden. However, there is no single drug that addresses both issues simultaneously....
