Such growth increases the size of skeletal muscles and can be achieved by muscular training, increased use of muscles, and the use of some hormones such as anabolic steroids (testosterone). Some types of muscle training such as weight bearing or (2) training specifically enhance the growth of muscle fibers. Muscle (3) is a condition of decreased muscle bulk, also referred to as muscle (4). This can occur as a result of many conditions: poor nutrition or starvation, and (5) of muscles for a protracted time. Some chronic diseases and medical conditions can cause reduced muscle mass e.g., cancer, tuberculosis, AIDS, etc. A decrease in muscle mass can also be found as people grow older, and such a condition is called (6).
