True
hypertrophy is when the cells in a muscle duplicate and cause the muscle to get larger
atrophy is a decrease in muscle mass. Hypertrophy is muscle growth.
Certain forms of muscular dystrophy are x-linked, cause weakness, and can cause muscular hypertrophy as muscle cells are replaced with fat.

Exercise and working out
Directly, I think that it doesn't cause wastage. It may cause some muscle atrophy due to lack of exercise.
In Resistance Training, concentric and eccentric contractions are two movements done by opposing muscles. Eccentric contractions are said to cause delayed onset of muscle sorennes( DOMS).
There are various ways through which exercise will effect muscle fatigue. This will enhance blood circulation which will deliver more oxygen to the fatigued muscles. Exercise will also cause lactic acid to be released.
well any exercise will cause a muscle to grow stronger but if you mean to gain volume then you want to do anaerobic exercise (less reps more weight)
The most direct cause of muscle fatigue during any exercise in direct heat is dehydration of the body system as well as excessive build up of lactic acid.
OVERHEATING
Warm-up exercise include stretching and exercices of moderate intensity that cause sweating and increase in muscle temperature.
