Then they will review the scientific research topics. Let's take a look at the opening report of the sports major in universities.

Title: Effects of Calisthenics on College Students' Cardiovascular System

Professional Name: Sports Major

Class ID: ******

Student Name: Liu **

Supervisor: Zhou **

I. Selection basis

Bodybuilding is no longer a purely competitive sport, it has gradually been accepted by college students, and has become a bright flower of the campus campus sports culture, injecting new vitality into the campus [1].

After 3 years of aerobics study, the author found that aerobics can not only satisfy college students' interest in participating in sports, but also improve physical fitness and athletic ability, especially the impact on their cardiovascular system.

The heart is the driving force in the circulatory system, which promotes blood flow, provides sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and takes away the end products of metabolism (such as carbon dioxide, urea, and uric acid, etc.), so that the cells Maintain normal metabolism and function; various endocrine hormones and some other humoral factors in the body also need to be transported to target cells through blood circulation to achieve body fluid regulation and maintain a relatively constant body environment; in addition, the realization of blood defense functions And the relatively constant regulation of body temperature also depends on the continuous circulation of blood in the blood vessels, and the circulation of blood is achieved by the role of the heart "pump".

The heart is essential for maintaining human movement and life activities, and different forms of exercise and exercise intensity also have different effects on the heart.

Exercise as a kind of stress will have a certain impact on the various systems of the body. When the body is under load, the cardiovascular system also changes accordingly under the regulation of neurohumoral fluids to meet metabolic requirements.

The response of the heart to different types of body load is different, and with the process of adapting to the body load, the shape, structure and function of the heart have corresponding compensation changes.

Significance of research purpose

I understand the current popularity of aerobics in universities, and compare students who have participated in aerobics training with untrained people through questionnaires and experiments, analyze the effects of aerobics on the cardiovascular system, and participate in aerobics for college students. Sports training provides a reference.

3. Research Status at Home and Abroad (Literature Review)

1. Current development trend of aerobics

The living standards of Chinese residents have been continuously improved, and more and more people have begun to pay attention to the improvement of the quality of life. The improvement of the quality of life requires a healthy body as a support and carrier. How to use their spare time to keep their bodies and minds healthy has become a topic of great concern to every resident.

At present, aerobics is widely developed in developed western countries as one of the ways to improve the health of domestic citizens. Among these diverse sports, aerobic exercise is the most effective way to improve people's health. Richness and economics, so that more and more people understand and participate in it, which plays an important role in improving the quality of life of people in China, cultivating a healthy lifestyle, constructing a diverse community of sports, and launching national fitness programs. effect. On the other hand, college students in our country have a heavier learning burden and less exercise time, which has led to a marked decline in health status. Therefore, formulating reasonable and effective fitness exercise prescriptions to improve the physical health of college students has become one of the hotspots [3].

Bodybuilding is an aerobic exercise, and people have reached a consensus on its fitness function. Studies have shown that people who regularly participate in aerobics exercise have a significantly higher total heart volume index than those who have not participated in exercise, and their oxygen intake has increased significantly. Aerobic exercise can develop the cardiopulmonary function of the human body most, strengthen the heart muscle, increase the vitality of the lung, and reduce cardiopulmonary respiratory diseases. Aerobics not only has the effect of aerobic exercise, but also has the function of developing the flexibility and sensitivity of the body. Therefore, experts believe that aerobics is an ideal sport for the development of overall physical fitness [4].

2. The effect of aerobics on the cardiovascular system

The heart is one of the organs of humans and vertebrates and is the driving force in the circulatory system. The role of the heart is to promote blood flow, provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and take away the end products of metabolism (such as carbon dioxide, urea, and uric acid), so that cells maintain normal metabolism And functions; various endocrine hormones and some other body fluid factors in the body also need to be transported to target cells through blood circulation to achieve body fluid regulation and maintain a relatively constant environment in the body; in addition, the realization of blood defense functions and body temperature are relatively constant The regulation of blood pressure also depends on the continuous circulation of blood in the blood vessels, and the circulation of blood is achieved by the role of the heart "pump". The heart is essential for maintaining human movement and life activities, and different forms of exercise and exercise intensity also have different effects on the heart [5].

Long-term adherence to aerobics exercises can increase the number of capillaries, improve the elasticity of blood vessels, increase the diameter of blood vessels, and reduce blood flow resistance, thereby enhancing cardiovascular function. Classmates who often adhere to aerobics exercise have significantly improved cardiovascular function and cardiopulmonary function, which is manifested by a decrease in quiet heart rate and a significant increase in vital capacity, indicating that aerobics has a significant promotion effect on the respiratory system and aerobic endurance. Cardiovascular and respiratory functions have also improved significantly. This shows that practicing aerobics can enhance the strength of the respiratory muscles, increase the maximum oxygen intake, and increase the hemoglobin content. As a result, the body's oxygen intake, oxygen transport, oxygen storage, and oxygen use have been significantly improved, and aerobic endurance has been significantly improved [6].

3. It is significant for current college students to learn aerobics training

College students are growing mature and shy, especially sensitive to adolescent body shape, envious of slenderness, do not want to gain weight, but do not like strenuous exercise (such as long-distance running), afraid of the sun, afraid of competitive and antagonistic sports; afraid of others Seeing myself in motion. And aerobics is a sport that really suits us. Its exercise intensity is medium, and the exercise intensity is suitable and easy to control. Under this exercise intensity, the heart rate can be kept within the aerobic working range for a long time. It is safe, reliable, beautiful and lively, and in terms of amount of exercise, completing a set of aerobics is no less than running a long-distance run, but it does not feel tired to perform movements with music. Aerobics not only has high exercise value, and the amount of exercise can be adjusted at will, but also is not restricted by the climate and the venue. It can help to eliminate fatigue and invigorate the whole body. It also helps to enrich the cultural life on campus, improve students' aesthetic ability, and cultivate conscious exercise Physical good habits play an important role in promoting friendly exchanges among students and further promoting the construction of spiritual civilization. Long-term adherence to aerobics exercises can enhance cardiovascular and respiratory system functions, and significantly improve various physical qualities.

Cardiopulmonary function is significantly improved, specifically as a decrease in quiet heart rate and a significant increase in vital capacity, indicating that aerobics has a significant promotion effect on the respiratory system and aerobic endurance. Cardiovascular and respiratory functions have also improved significantly. This shows that practicing aerobics can enhance the strength of the respiratory muscles, increase the maximum oxygen intake, and increase the hemoglobin content. As a result, the body's oxygen intake, oxygen transport, oxygen storage, and oxygen use have been significantly improved, and aerobic endurance has been significantly improved. At the same time, aerobics exercises have a significant effect on improving cardiac function. Myocardial tissue is like other tissues. Long-term and moderate-intensity exercise can increase its contractility, improve coronary circulation and capillary proliferation, and provide sufficient nutrition. The muscles are strong, the heart volume is enlarged, the ventricular wall is greatly thickened, and the heartbeat is slow and powerful. Therefore, it is significant for college students to learn aerobics.
