In our daily life, it is necessary to exercise in order to adapt our body to our life and to keep our body physically ready for the events we will experience. It should be known how important skeletal muscle is in the successful fulfillment of different types of physical activities (eg 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 disease types; It is also effective in defining skeletal muscle function activity limitations and the extent and characteristics of the disorder.
The main function of 600 muscles in our body is to convert chemical energy (fat and carbohydrate) into mechanical energy. This creates strength. The force is transferred from the active muscle fibers to the tendons, the points where the muscles attach to the bones. The movement of the tendons on the bone also creates a movement in the joints. In principle, force can occur in a short time; The result, which is generally defined as muscle strength, occurs, or power generation may spread over a period of time. This condition is also called muscular endurance. In the clinical setting, failure to generate short-term strength is referred to as weakness, while inability to exert 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 about 50% of the total body proteins. In addition to building strength, skeletal muscles contribute to basal metabolism, generate heat to maintain core temperature, regulate blood sugar, act as a reservoir for carbohydrates, lipids and amino acids, aid in energy production 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 was associated with gait speed, balance, time to get out of a chair, ability to climb stairs, fall frequency, and survival rate. This evidence strengthens the belief that maintaining and increasing muscle strength and endurance throughout life will reduce the constraints of daily life.
