Muscles respond to exercise in a number of ways both during and after workout. Exercise improves your muscle, strength, speed power and endurance.
Muscle changes will start with resistance exercise. When this resistance is greater than what your body is typically encounters during the day, the process of muscle Hypertrophy or muscle building is activated.
Intense exercise causes Trauma to Muscle Fibres resulting in small microscopic tears in the tissue. The size and severity of it depends on exercise intensity. Tears in the muscle tissue activates special Satellite Cells that rushed to the damaged area. These cells replicate and mature into grown cells and fused to your muscle fibres.
This process forms new muscle protein strands. Which increases the strength and size of the muscle, resulting in overall muscle growth.
Exercising specific muscle regularly can increase their size by up to 60%. Not all forms of sports can increase muscle size. Some sports rely more on Coordination and Control than on physical power and strength.
Frequent exercise leads to improved muscle coordination. It trains the muscle to work more effectively and efficiently, by working together. As a result of long-term exercise, blood supply to the muscle increases. This improve the delivery of various Nutrients, Minerals And Vitamins to the muscles. Which makes you more effective and faster at regenerating after injury or workout.
After regular exercises, muscles store large amount of glycogen for energy. Size and quantity of Mitochondria (powerhouse of cells) also increase in muscle cells. Which results in an increased rate of energy production.
Active muscles are excellent for dealing with the food energy. Both fat and sugar enzymes involved in energy production becomes more efficient and speed up metabolism.
If you are Sedentary, the muscle becomes less able to absorb glucose. It is also less able to help burn off fat which can accumulate in the arteries, leading to an increased risk of stroke and heart diseases.
Our muscles have evolved to perform in this way, which suggests that humans are meant to be Active On Their Feet.
