Muscle weakness is sneaky. It often appears gradually and makes once-simple tasks harder — like having to rock back and forth to get out of a chair or tug a few times on the car door to open it. More than an inconvenience, muscle weakness has a domino effect on health. It slows your metabolism how fast your body burns energy, puts more pressure on your joints, hurts your posture, throws off your balance, and limits your mobility. You walk slower and become dependent on others to do things. Physical limitations lead to social limitations, and there’s a downward spiral from there,” says Marian Hannan, professor of medicine at Harvard Medical School and co-director of the Musculoskeletal Research Center at Hebrew SeniorLife’s Institute for Aging Research. Sudden muscle weakness could be a sign of a stroke — the interruption of blood flow to the brain that occurs when a blood vessel is blocked or ruptures. Stroke weakness usually occurs on one side of the body, especially in the face, arm, or leg. It may also be accompanied by at least one of the following. If any of these symptoms occur, call immediately. Do not attempt to drive yourself or someone else with these symptoms to the hospital.

Dieting muscles will weaken
The saying goes there are two certainties in life: death and taxes. But men should also add loss of muscle mass to the list. Age-related muscle loss, called sarcopenia, is a natural part of aging. Less muscle means greater weakness and less mobility, both of which may increase your risk of falls and fractures. A report from the American Society for Bone and Mineral Research found that people with sarcopenia had 2. But just because you lose muscle mass does not mean it is gone forever. Thomas W. Storer, director of the exercise physiology and physical function lab at Harvard-affiliated Brigham and Women’s Hospital. One possible contributor to sarcopenia is the natural decline of testosterone, the hormone that stimulates protein synthesis and muscle growth.
