1 Introduction 1.1 The significance of research Since the advent of humans, the living environment and lifestyle have undergone tremendous changes. In the early days, human beings lived in an environment full of dangers, food and clothing, and survival is undoubtedly the first requirement of the human ancestor. In the long natural selection, it can walk upright, using tools and a series of physical labor, and nature has endowed human beings. Healthy and robust, with the development and progress of science and technology, the degree of mechanization and automation is gradually improving, and people’s physical labor is getting lower and lower. If there is no physical exercise, muscles will shrink, physical condition will deteriorate, and the body’s ability to move will increase. The weaker, the lack of physical activity will make it difficult to face complicated, highly competitive and fast-paced societies and take active part in fitness activities. 2 Research objects and methods 1 Research targets General fitness workers 2.2 Research methods Through the methods of manual review and online data access, the authors reviewed monographs about fitness and health. 3 Results and Analysis 3.1 Fitness exercises can effectively improve the body shape 3.1.1 Fitness exercises can enhance bone function. He has been engaged in fitness exercises for a long time. Through the blood circulation of bones, the metabolism of bones is strengthened, bone diameters are increased, bones are thickened, and the bone's resistance to bending, bending and compression is enhanced. Due to different fitness programs, the effects on the human skeleton are also different. Often engaged in lower limb activities mainly fitness projects, such as running, jumping on the lower limbs have a greater impact, often engaged in upper limb activities mainly fitness projects, such as weight lifting, throwing, etc., have a greater impact on the upper limbs. The effect of physical fitness is not always. When the physical fitness stops, the impact on the bones will gradually disappear. Therefore, physical fitness should be regularized. Moreover, sports and fitness programs should be diversified to promote the coordinated development of bones and muscles. Middle-aged people in high altitude areas should choose push-ups, bench presses, pull-ups, squats, weight lifting, frog-jumping, duck-steps, and sit-ups. In the high-altitude areas, the elderly should choose lighter weight dumbbell exercises such as flying birds, chest expanders, horses and quiet, no weight lifting, sit-ups and other strength exercises. 3.1.2 Fitness exercise is the best medicine for body weight loss. The body's weight gain or even obesity is caused by an imbalance in energy intake and energy expenditure. For adults, increased or excessive body fat accumulation is a key factor in weight gain or obesity. Obesity can damage the body's cardiovascular function, respiratory function, liver and kidneys, increase the burden on bones and muscles, and cause osteoporosis and muscle damage. In the case of dietary control, regular physical exercise can achieve the best weight and body composition, because aerobic exercise can greatly increase the body's calorie consumption. For example, the maximum aerobic exercise can increase energy consumption by 1020 times. 2. Therefore, in the high altitude areas, the elderly should choose some long-term exercises that use large muscle groups, such as: more than 2 minutes of striding, more than 12 minutes Long distance jogging, 12-minute skipping, aerobics, square dance and other sports are ideal. 3.1.3 Fitness exercises can make the human muscles even and plump. The good effect of exercise on muscles is manifested in many ways: , can purposefully increase muscle volume, which muscles to train, and which muscles increase in volume. Second, can effectively increase muscle strength, a few weeks of fitness exercise will cause a significant increase in muscle strength. Third, can increase the flexibility of muscles, develop good physical exercise habits, can increase the flexibility of muscles. Health-friendly muscle is a symbol of health and beauty. Middle-aged people in high altitude areas should choose to push-ups, bench presses, frog leap, squats, weightlifting and other strength exercises are more ideal, the elderly should choose, Ma Bujing, slow pick up, do not bear heavy lifting, inclined push-ups, Dumbbell chest and other strength exercises are ideal. 3.2 Fitness exercises can enhance physical fitness and improve physical exercise. Physical fitness and physical exercise ability are important signs of health. The quality of body is related to congenital inheritance, but it has obvious acquired plasticity and the body is adaptable. Weak and physical quality are closely related, but not the same, adhere to scientific fitness, can effectively enhance physical fitness and improve physical exercise capacity. 3.2.1 Fitness exercises can improve physical fitness. Fitness exercises can enhance the physical qualities of physical fitness such as strength, speed, endurance, agility, flexibility, coordination and balance. Strength is the ability of the human body to show muscle tension or contraction. It is the basis for physical exercise and physical labor. Fitness exercises increase muscle strength. Especially after adolescence, you can improve the strength of various parts of your body through different methods of fitness. Endurance quality can be interpreted as the body's ability to fight fatigue and recover from fatigue. The increase in endurance quality is mainly achieved through aerobic fitness activities. 2.2 Fitness exercises can effectively improve the body's ability to adapt to the outside world. Physical fitness is an important expression of health. The adaptability of the body is mainly manifested in the ability of the human body to adapt to various internal and external environmental changes and to regulate various social psychological factors. First of all, fitness exercise can enhance, physiological function and resistance, thus improving the adaptability to the natural environment. Fitness exercises can sometimes make full use of the natural resources that nature has given to humans, absorb solar ultraviolet rays through sunbathing to stimulate the central nervous system and improve human immunity. Through the air bath and forest bath and other fitness methods, the body's ability to adapt to the external environment is improved. To oxygen, camphor, fitness and health effects. Fitness activities are good medicines for regulating the state of the heart, and have functions such as catharsis and emotional transfer. Therefore, actively participating in fitness exercises can maintain a good psychological state, regulate bad moods, and promote the healthy development of the body. 3.3 Fitness exercises can prevent, treat and cure various common chronic diseases. Modern people living in a busy and stressful city, due to sedentary sitting, lack of exercise, can easily cause headaches, fatigue, insomnia, memory loss, hypertension, coronary heart disease, bloating, constipation. With other diseases, it is necessary to strengthen scientific fitness. 1 Effects of exercise on the cardiovascular system. When people exercise, due to the increase of energy consumption in the body, metabolites increase, that is, the power of contraction increases, the number of times increases, and the amount of blood circulation increases, so as to ensure a higher metabolic level in vivo. 3. When the activity is, the function of the heart Change has become a factor in the improvement of cardiac function, and long-term adherence to scientific exercise can improve and enhance the structure of the heart. Replace your comb with your fingers, comb your hair from the front of your forehead and back to your neck, then straighten your ears to your ears and behind your ears to improve your brain's blood supply, keep your brain cool, and lower your blood pressure. Good prosthesis is a guarantee for cardiovascular and cerebrovascular, respiratory system work in quiet, and helps to eliminate muscle fatigue. When fitness, brain cells related to fitness exercise are in excited state, so that cerebral cortex management thinking Partial rest is helpful to relieve mental fatigue. 2 Effects of exercise on musculoskeletal system. Fitness exercise has no need for exercise intensity for the prevention of lumbar spondylosis, cervical spondylosis, frozen shoulder, and the maintenance of muscle, tendon and ligament flexibility. The best exercise program is aerobics and square dance, and the key lies in the exercise rate of aerobics. To be in place; for the prevention of lumbar spondylosis and cervical spondylosis, the back movements of the waist and neck are mainly in place; for the prevention of periarthritis, the arm movements must be in place. The various aerobic exercises are designed according to the anatomical and physiological features of the human body, and also have the effect of increasing synovial fluid in the joint cavity and protecting the articular cartilage surface. Therefore, the aerobics exercise is also the best exercise program for preparatory activities before the exercise. 3 Effects of exercise on digestion and respiratory function. Scientifically engaged in physical exercise can make a good improvement in the structure of the heart. The human digestive system looks like a food processing plant. Its role is to digest and absorb nutrients. It is mainly composed of the digestive tract consisting of the oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, and anus, as well as salivary glands, liver, and pancreas. The food we usually eat must be digested by the digestive tract and the complex processing of the pancreas in order to become nutrients that the body can absorb and use. During physical exercise, metabolism is greatly enhanced than usual, and nutrients are consumed in large amounts. Metabolism is 10 times or even 20 times more effective than during quiet exercise. When the physical activity is over, the substances consumed by the body must be replenished in time, and it is necessary to take in more substances from the outside world. After the processing of the digestive system becomes the substance in the body, it is clear that the work of the digestive system is much larger than the original. Once you have a doctor, it improves the function of the digestive system. There should be a certain time interval between fitness and eating. After a meal, it is not advisable to engage in vigorous physical exercise. After a fitness exercise, it is advisable to take a rest and then eat. Otherwise, it will affect the body's ability to digest and absorb. 3.4 The Negative Effects of Blind Engaging on Fitness Sports Health physique requires physical exercise to ensure that blind physical fitness can have adverse effects on the body. Sometimes blind fitness can only be twice as effective and even counterproductive. Because of physical exercise, there is a reasonable exercise load valve. Exceeding this range may not only be useless to the body, but it will be harmful. And unscientific fitness methods can also have adverse effects on the body. Stronger delivery capacity, slower growth, and relatively low yields. The increase of stem diameter at the jointing stage of BMS002 was most obvious, and the width of the leaves changed significantly and the yield was high. Yucao No. 3 and Yucao No. 4 BMS002 have high yield and adaptability. They are adapted to promote cultivation in areas with similar climatic conditions, can meet the needs of high-quality silage production, and open up vast feed for the development of animal husbandry in alpine regions. Forage route.
