Examples of this are osteoporosis, a form of bone atrophy where the bone experiences a loss of minerals and proteins. Muscular atrophy is the wasting away of skeletal tissue which causes muscular weakness, a reduced capacity for aerobic metabolism, loss of flexibility, cardiovascular degeneration, with increased heart rate, decreased stroke volume, decrease V02 max, and increase of blood pressure. All of these things can be avoided or put off by exercise. Sacrcopenia which refers to the vanishing of flesh where estrogen helps moderate the production of a hormone that helps to develop and promote muscle growth.
