Long-term bodybuilding exercises can develop muscles and increase strength; improve and improve the function level of internal organs such as the cardiovascular system, respiratory system, and digestive system; increase the function level of the central nervous system; regulate mental activities and cultivate good sentiment; improve body shape, Correct deformities, etc.
1. Muscular
The human organs of movement are composed of muscles, bones, joints and ligaments. In accordance with the natural law of "use advancement and disuse retreat", various action methods in bodybuilding exercises have a positive effect on sports organs, so that muscle fibers gradually become stronger and stronger, and muscle strength is enhanced. Long-term bodybuilding exercises can increase the physiological cross-section of muscles and make muscles full. At the same time, it can promote the metabolism of bones, improve the tensile and torsion resistance of bones, and play a good role in promoting the growth and development of joints and ligaments.
2. Improve the functional level of internal organs such as the cardiovascular system, respiratory system, and digestive system
(1) Cardiovascular system
Fitness and bodybuilding exercise can increase the capacity of the heart and increase the elasticity of blood vessels, thereby making the heartbeat stronger, increasing the stroke output, and reducing the heart rate (<60 beats); it can also increase the number of red blood cells in the blood, thereby increasing the body's absorption Nutritional capacity. Fitness and bodybuilding exercises have significant effects on cardio training. It is mainly manifested as: in a quiet state, the number of heartbeats is reduced, and the circulating blood increases and the contraction of the heart muscle become more powerful. Each time the heart contracts, the heart itself can be completely emptied, and the stroke volume and heart output capacity increase. Generally, the decrease in heart rate when completing a prescribed amount of exercise is used as a sign of training performance. ①The improvement of cardiac efficiency can make more blood flow to each part of the muscles, thereby providing more fuel and oxygen, so that athletes have the ability to achieve higher levels of exercise. ②The training effect of the cardiovascular system can enable athletes to recover their heart rate and blood pressure faster after stopping the exercise, reaching the level before the exercise. ③Bodybuilding training can reduce the demand for oxygen by the muscles in exercise, thereby reducing the demand for blood, which can ensure that the heart can fully supply the demand for blood of other organs in the body
(2) Respiratory system
Fitness and bodybuilding exercises can increase the depth of breathing, increase the amount of gas exchange during each breath, and improve the function of the respiratory system, so as to ensure that the needs of gas exchange during intense exercise are met, and the functional level is improved. During training, the respiratory frequency characteristic curve will also be improved. Generally speaking, as the efficiency of the cardiovascular system increases, the efficiency of the respiratory system also increases accordingly.
(3) Digestive system
Fitness trowel can also improve the function of the digestive system. Because muscle activity consumes a large number of nutrients, it needs to be supplemented in time, and muscle activity can increase gastrointestinal motility, increase digestive juice secretion, and improve digestion and absorption.
3. Improve the functional level of the motor nervous system
In the central nervous system, the structure that regulates posture and movement is called the motor nervous system. It is mainly composed of three hierarchical ladder structures (the spinal cord, brainstem, and cerebral cortex) and two auxiliary monitoring systems (cerebellum, basal ganglia). These brain areas have interactive circuits, which are both distributed and parallel processing and processing of motion and posture parameters. Long-term bodybuilding exercises can enhance the accuracy of the exercise system in regulating human muscles, enhance the accuracy and coordination of human movements, and prevent human body injuries during exercise.
4. Improve body shape, correct deformity
Bodybuilding has a special healing effect on correcting certain deformities or defects of the human body. Whether it is due to congenital or acquired body shape or defects, such as chicken breasts, breasts, or local muscle contractions caused by diseases, muscle weakness, etc., they can be targeted to achieve a certain therapeutic effect through fitness training. For this role of exercise, certain actions have been further used in medical sports.
5. Adjust psychological activities and cultivate good sentiments
Human mental activity is the reflection of the human brain to external objective things. The body will become tired after intense physical or mental work. The tense rhythm of modern life can make people feel depressed or other bad emotions. Regular bodybuilding exercises can be used to regulate mental activities and cultivate sentiment, and make people have a healthy mentality of working hard and seeking a better future.
