Question

• How do diet and exercise affect muscle size?​

Answer 1

To make gains you have to have the right nutrients in your body to construct muscle. This means that what you eat, and how much, is essential in making muscle gains. Lifting and doing strength training without adequate nutrition, especially without enough protein, can actually lead to loss of muscle tissue.

Muscle tone referring to the activity of the muscle, not toned muscles in the traditional sense decreases and the interstitial fluid and blood pumped into the muscles during the workout disperses, causing your muscles to appear smaller. But again, it takes a long time for you to actually lose muscle size.

Answer 2

Resistance exercise affects muscles by increasing the formation of myofibrils, thereby increasing the thickness of muscle fibers

Step-by-step explanation:

This added structure causes hypertrophy, or the enlargement of muscles, exemplified by the large skeletal muscles seen in body builders and other athletes.
