Physiological principle of strength training: in muscle cells, mitochondria mainly provide energy to make muscles move. Muscle strength means that you can consume more energy to exercise, so the purpose of training strength is to make mitochondria in muscle cells grow in large numbers, thus decomposing more glucose to produce energy.
When muscles are developed, it is very difficult to pinch them with your hands. It means that there is still water in the muscles to support the bones.
Strength training is the physical foundation of all sports. Strength ability is not only manifested in the strength of physical exercise, such as the weight lifted at one time, the ability of the body to support or hold heavy objects, etc. It also reflects the ability of the nervous system to mobilize and dominate muscle participation and the energy supply of biochemical metabolism in the human body.
Strength is not only restricted by technology, but also the level of human physiology and biochemistry related to strength is the key to restrict the level of strength.
Relationship between strength and speed, endurance and flexibility: strength and speed, endurance and flexibility are inseparable. Speed, endurance and flexibility are also important hand exercises to improve strength, and strength training also includes speed, endurance and flexibility. In addition, strength training should be combined with other quality training for different purposes, which can comprehensively improve people's comprehensive quality.
