INTRODUCTION
Aerobics is an exercise method with beautiful musical rhythm as the primary tool. Aerobics can improve the coordination of the human body while maintaining the standard posture of the human body. Aerobics sports to fitness, heart, and bodybuilding as the primary goal. It integrates music, dance, gymnastics, and aesthetics. Aerobics is known worldwide for its intrinsic values and appeal.11 Mohamed AA, Alawna M. Role of increasing the aerobic capacity on improving the function of immune and respiratory systems in patients with coronavirus (COVID-19): A review. Diabetes Metab Syndr Clin Res Rev. 2020;14(4):489-96. Aerobics is a sport that is entertaining, ornamental, graceful, rhythmic, and able to express emotions. It is widely used in physical education in colleges and universities. This article focuses on college athletes. This paper uses two different aerobics exercises, high-intensity, and low-intensity, for experiments. This paper aims to analyze the effect of two different aerobics exercise methods on improving cardiopulmonary function and promoting the development of body shape.
METHOD
Subjects
This paper uses 40 people as the research sample. The living and learning conditions of the subjects were the same. In this paper, 40 students were divided into two groups for research.22 Nikniaz L, Ghojazadeh M, Nateghian H, Nikniaz Z, Farhangi MA, Pourmanaf H. The interaction effect of aerobic exercise and vitamin D supplementation on inflammatory factors, anti-inflammatory proteins, and lung function in male smokers: a randomized controlled trial. BMC Sports Sci Med Rehabil. 2021;13(1):1-8. There were no significant differences between subjects’ age, height, and weight group.
Investigation method
A (high load group) designed an exercise regimen with a maximum heart rate of “220-age”. Volunteers first did a 5-minute prep activity and a 20-minute body posture exercise. Finally, the volunteers did 20-30 minutes of running and jumping or step aerobics. B (low-load group) designed a “195-age” maximum heart rate as an exercise regimen. Volunteers first did a 5-minute prep and a 15-minute body bar exercise.33 Alyafei A. Aerobic Capacity and Regular Physical Exercise among Tobacco Smokers. Research International Journal of Community Medicine and Public Health. 2021;2(1):1-4. Finally, the volunteers did fifteen minutes of aerobics or running and jumping exercises. The experimental and control groups were given 40-60 minutes of exercise. The entire training cycle is eight weeks. In this paper, POLAR was used to measure the kinematic performance of athletes.
MOD simulation of muscle electricity and life in sports aerobics
The contribution rate of muscle EMG activity is the percentage of the total energy of each EMG to the sum of the overall EMG values of 11 muscles.44 Duke JW, Lovering AT. Respiratory and cardiopulmonary limitations to aerobic exercise capacity in adults born preterm. J Appl Physiol. 2020;129(4):718-24. Its formula is as follows:
In this paper, the principal, side effects, and antagonistic effects E of the four experimental groups are analyzed, and the corresponding expressions are given:
The four groups of muscles were biceps and triceps, serratus anterior and lower trapezius, pectoralis major and latissimus dorsi, anterior deltoid, and infraspinatus. This paper gives a complete body characteristic parameter.55 Naik KE. Influence of aerobic exercises on cognitive abilities among children. Inter J Health, Physc Educ Computer Sci Sports. 2020;38(2):75-7. The content includes the physiological cross-sectional area of the body, the maximum stress value of the most extensive tissue, and the mathematical model of the body. The effective muscle strength formula is as follows:

Diabetes Metab Syndr Clin Res Rev. 2020;14(4):489-96. represents the cross-section of the human body. F1 indicates maximum tissue stress. L1 represents a model of muscle contraction during reverse movement. L2 represents the modality of the muscle. D1 represents the derivative of both.66 Alqahtani AS, Alajam R, Eickmeyer SM, Vardey R, Liu W. Feasibility and trend of pulmonary function in a pilot trial of aerobic walking exercise in non-ambulatory stroke survivors. Top Stroke Rehabil. 2020;27(3):190-8. The preliminary design of the model can be selected based on the model’s height, weight, age, and gender.
Mathematical and statistical methods
In this paper, paired and group experiments were used to conduct statistical analysis of the obtained data, and the difference value of the results was taken as 0.05. There is no need for a code of ethics for this study.77 Alawna M, Amro M, Mohamed AA. Aerobic exercises recommendations and specifications for patients with COVID-19: a systematic review. Eur Rev Med Pharmacol Sci. 2020;24(24):13049-55.
There is no need for a code of ethics for this study.
Ethical Compliance
Research experiments conducted in this article with animals or humans were approved by the Ethical Committee and responsible authorities of Minjiang University following all guidelines, regulations, legal, and ethical standards as required for humans or animals.
RESULTS
The weight and waist circumference of the students in group A decreased, but there was no statistical significance. This suggests that high-intensity fitness exercises can change weight and shape.88 Wickerson L, Brooks D, Granton J, Reid WD, Rozenberg D, Singer LG, et al. Interval aerobic exercise in individuals with advanced interstitial lung disease: a feasibility study. Physiother Theory Pract. 2021;37(9):1034-42. The weight and bust circumference of the students in group B decreased but was not statistically significant. This suggests that low-intensity training had no apparent effect on body shape. (Table 1)
The effects of exercise intensity on the heart and lungs were better. (Table 2) There was no significant change in the two experimental classes before and during the training of diastolic blood pressure.99 Kampert M, Singh T, Finet JE, Van Iterson EH. Impact of wearing a facial covering on aerobic exercise capacity in the COVID-19 era: is it more than a feeling?. Clin Res Cardiol. 2020;109(12):1595-6. After eight weeks of training, the athletes’ heart rate decreased, blood pressure decreased, and lung function returned to normal. The resting heart rate was significantly lower in both groups than before training. This shows that eight weeks of regular exercise improves output per heartbeat. At rest, the heart rate can reach the body’s regular metabolism. Reduced blood pressure is also an average change in the heart and lungs. This correlates with increased vagal tone after training.1010 İşleyen G, Dağlioğlu Ö. The effect of aerobic exercise on pulmonary function and aerobic capacity in sedentary men. IJSETS. 2020;6(3):80-7. There was a significant difference in lung activity between the two groups of volunteers after exercise (P<0.01). The results showed that both different calisthenics exercises could improve the patients’ breathing capacity.
Comparative analysis of heart rhythm and pulmonary function parameters before and after exercise in groups A and B.
DISCUSSION
Aerobics is a comprehensive and dynamic sport. During exercise, the secretion of hormones increases due to the stimulation of the sympathetic nerves. At the same time, aerobics exercise can also lead to insulin secretion and significantly increase lipoprotein lipase activity.1111 Park K, Lee S. Changes in Respiratory Function Due to Differences in Mask Blocking Grade and Effects on Cardiovascular Function during Aerobic Exercise with Mask. Phys Ther Rehabil Sci. 2021;10(3):289-96. This can speed up the body’s metabolism by speeding up the body’s consumption. One hour of aerobics can reduce the energy by about 21 kcal, 2.3 kg of heat generated by the decomposition of fat. This can reduce about a month of 1.5 kg of body weight and help people stay in shape while exercising. Aerobics exercise regularly trains all body parts, joints, and bones. Long-term aerobics can significantly reduce fat deposits. College students who regularly engage in national fitness exercises can make muscles, bones, and joints develop in harmony.
Aerobics improves the ability of the central nervous system to regulate the circulatory system and enhances the elasticity and tension of the arterioles. This lowers blood pressure.1212 Hedlund E, Lundell B. Endurance training may improve exercise capacity, lung function and quality of life in Fontan patients. Acta Paediatr. 2022;111(1):17-23. The athlete’s heart rate increases by 150 beats after doing aerobics, in which case the strength of the respiratory muscles can be increased, and the maximum oxygen intake can be increased. Increasing the hemoglobin level in the process also increases the speed of aerobic exercise. Aerobics has a more significant impact on the heart muscle. Prolonged and moderate physical activity can increase contractile strength and improve coronary blood flow and capillary proliferation. Before and after the experiment, the heart rate of the aerobics training group increased significantly. Some people present with sinus arrhythmia. This shows that long-term aerobics does have a specific effect on improving people’s physiological functions. After a period of aerobics, the body’s breathing becomes more profound. This is one of the most beneficial and effective breathing methods. This process allows the breathing muscles to get plenty of rest. Therefore, the body’s metabolism is more powerful. Aerobics activities have moderate intensity, moderate density, and long training periods. Aerobics athletes can effectively exercise students’ heart and lung function.1313 Abdelbasset WK, Osailan A. Sleep quality and ventilatory efficiency in elderly heart failure patients: a pilot study on the short-term effect of 4-week low-intensity aerobic exercise. Kardiologiia. 2020;60(6):102-6. It can effectively enhance the circulation of the human body and promote the metabolism of the respiratory system and digestive systems. This exercise is conducive to the healthy development of the body. College students’ self-awareness and initiative awareness are outstanding in aerobics. During training, the student’s heart rate is 150-160 beats per minute. Aerobics exercise for a long time can strengthen the respiratory muscles’ elasticity and improve the respiratory system’s oxygen exchange. This can improve the cardiac function of college students. Aerobics is great for the heart and lungs.
Especially after aerobics, the heart rate is lower in the resting state, and the lung capacity is significantly increased. The heart rate was significantly lower between both groups compared to before training. This shows that regular training improves every output of the heart and lungs. At rest, the heart rate can reach the body’s regular metabolism. Reduced blood pressure is also an average change in the heart and lungs. This correlates with increased vagal tone after training. There was a significant difference between the two groups in lung function before and after exercise (P<0.01). This shows that physical exercise has a significant effect on improving breathing ability. The effect of aerobics exercise on cardiopulmonary function is mainly due to the expansion of blood vessels during exercise, which reduces the resistance of the heart’s blood to the organs. The result is a reduced load on the heart. Aerobics can increase the heart muscle’s volume and strengthen the heart muscle’s contraction. The final result is to increase the output power of the heart.
CONCLUSION
The test subjects selected an 8-week aerobics training program according to the training intensity and volume. Studies have found that aerobic exercise can significantly improve resting heart rate, blood pressure, and lung capacity. And high-load aerobics training has a good effect on improving body shape and reducing weight. Aerobics is a relaxing and enjoyable way of exercise. The athlete can mobilize students’ sports enthusiasm. Aerobics can strengthen the body and encourage students to develop a correct posture. Aerobics can fully develop the body and mind.
