A Review of Ageing Effects on Skeletal Muscles

In recent decades, along with industrialization, improvements in public health and subsequently higher life expectancy indices, population of elderly people has been increased. The elderly ages are very important years of human life, because of progressive degeneration of human body tissues and its very deep impacts on physical performance. One of the most impressive changes is muscular tissue decrement and atrophy of skeletal muscles, so called “sarcopenia”. The disease is so debilitating and causes sever dysfunction, quality of life, and life expectancy of patients. In this article, most important aspects of ageing and muscle fiber changes and training effects on strength, endurance and composition of muscle fibers of elderly people are reviewed.
