Resistance exercise exerts particular muscles, and as a response, the muscles hypertrophy, causing them to grow larger and increase their work capacity.
not usually, usually it increases it. it really depends on the exercise you do.
Whenever you start becoming sedentary. It's less about age and more about exercise. You typically lose about a pound of muscle a year after the age of 40. This of course, as the answerer above noted, be offset by regular resistance exercise.
The long term effect of exercise is stronger muscles. With stronger muscles, your body won't tire as quickly as it used to.
in space there is very little resistance from lack of gravity so they get literally no exercise in space and they can lose muscle mass and bone density. also space suits are hard to move in.
It greatens your resistance to the pulling force of the Earth, with causes muscle cells to grow in size. This is made evident by low gravity situations on spacecraft; the low resistance causes the people to lower in muscle mass, therefore constant exercise is needed to maintain ones' own body.
exercise, muscle mass, and food intake
Not any more than other foods with complete proteins. And without resistance exercise (weightlifting), you're not going to see any appreciable increase in muscle mass, no matter how much protein you consume.
Answer: Your frame size will become larger so you will gain weight, but not from muscle mass. You can gain muscle mass from exercise.
Most likely not. Any regular activity, including exercise will maintain muscle mass in general.
Atrophy is decrease in muscle mass.
If you were talking about resistance training, the only measurable difference in size immediately after a strength training session would occur if you deliberately trained in such a way as to experience a "pump" in a muscle group. For a few minutes, that muscle group would be engorged with blood and might be slightly larger than normal. Of course, in the long term proper resistance training will increase your amount of lean muscle mass and that may (at least in men) increase the size of muscles.
Not directly. Air resistance depends on an object's shape and type of surface.
Anaerobic.Aerobic exercise involves strain being placed on the body for long periods of time. It usually builds endurance.Anaerobic exercise involves intense strain being placed on the body for short periods of time. It usually builds muscle mass.
