In our daily lives, it is necessary to exercise to adapt our body to our lives and to keep our body physically ready for the events we experience. It should be recognized how important skeletal muscle is in the successful performance of different types of physical activities (e.g. exercise, recreational, occupational and others) and participation in daily life and social obligations. In addition, skeletal muscles play an active role in primary and secondary types of diseases; It is also effective in defining skeletal and muscle function, activity limitations, and the extent and characteristics of the disorder.
The basic function of approximately 600 muscles in our body is to convert chemical energy (fat and carbohydrates) into mechanical energy. In this way, force is created. Force is transferred from active muscle fibers to tendons, that is, to the points where muscles connect to bones. The movement of tendons on the bone also creates movement in the joints. In principle, force can be built up in a short time; The result, generally defined as muscle strength, occurs or the force formation may extend over a period of time. This situation is also called muscular endurance. In the clinical setting, failure to generate short-term force is referred to as weakness, while inability to apply force is referred to as muscle fatigue. Skeletal muscle constitutes 40-45% of the total body mass, and 55% of the total muscle mass is distributed in the legs. Muscle contains approximately 50% of total body proteins. In addition to strength generation, skeletal muscles contribute to basal metabolism, generate heat to maintain core temperature, regulate blood sugar, serve as storage for carbohydrates, lipids and amino acids, assist in energy generation during exercise, and protect internal organs.
As a result, the dramatic plasticity of skeletal muscle under different conditions and environmental factors such as bed rest and exercise has made it an ideal target in treatment interventions.
Functionally, skeletal muscle strength has been associated with walking speed, balance, time to get up from a chair, ability to climb stairs, frequency of falls, and survival rate. This evidence shows that maintaining and increasing muscle strength and muscular endurance throughout life is a part of daily life. It strengthens the belief that it will reduce the cracking.
