What are the effects of exercise on the muscular system?

Answer 1

Exercise will make the muscle more effective and more efficient.

However different types of exercise will have different effects upon the muscles exercised.

For example high intensity low duration exercise will produce strength, size and power gains while low intensity long duration exercise will produce endurance type benefits. Tone; Refers to the state of readiness of a muscle. This is the state that a muscle is in when it is relaxed and how able it is to respond to its task. An unused, untrained muscle will have poor tone and will respond slowly and with greater difficulty to a task than a trained muscle. Posture; Refers to the way in which we hold our bodies when sitting, walking or running. Regular exercise performed correctly will encourage good posture which enables muscles to work efficiently and will help to prevent injuries. Hypertrophy; Is when a cell, in this case a muscle cell, increases in size through growth. Extreme hypertrophy may result in the cells splitting to create new ones. Atrophy; Is when a muscle shrinks due to injury or lack of use. Addition to the Answer There is a byproduct called Lactic Acid. This is the product that is produced as a result of exercise. It can also be the case of something that is quite serious as well, if there is Lactic Acid that is built up, and there is no active activity happening. This can be a sign of something more serious happening.
