The influence of exercise and fitness on human body is holistic, and it has a good effect on various systems and organs of human body.
(1) is helpful to prevent osteoporosis and muscular atrophy.
Bones are composed of organic and inorganic substances. Organic matter makes bones elastic and tough, while inorganic matter makes bones hard. The organic matter in the bone tissue of the elderly is relatively reduced, while the inorganic matter is relatively increased, so its bone tissue is brittle and prone to fracture. At the same time, the matrix and bone salt in bone tissue are relatively reduced, which makes osteoporosis. Participating in sports can make the bone diameter thicker, increase the bone density and improve the relative composition of bone tissue, thus preventing osteoporosis and fracture.
Muscle is mainly composed of muscle fibers and has four characteristics: contractility, stickiness, extensibility and elasticity. Through long-term exercise and fitness, the elderly can thicken muscle fibers and enhance the metabolic capacity and load-bearing capacity of muscle tissue, thus preventing muscle atrophy.
(2) It helps to slow down the aging process of internal organs.
Regular physical exercise helps to enhance the strength of respiratory muscles, increase vital capacity and make alveoli more elastic; It can make the shape, function and adjustment ability of human cardiovascular system adapt well, enhance myocardial strength and increase stroke output, thus slowing down the aging of internal organs.
(3) Promote metabolism and improve anti-fatigue and anti-aging ability.
Fatigue is a phenomenon that work ability and physical function are temporarily reduced due to activities.
Aging refers to the gradual aging of various organs of the body after a certain age.
Metabolism is a process of continuous material exchange and energy transfer between body tissues and surrounding environment. It is the essence of life. As long as life does not stop, metabolism will continue. However, after the age of 30, people's metabolic ability gradually declines, which affects people's normal life. If we want to change this situation, we must actively participate in fitness activities. It can promote human metabolism, balance synthesis and catabolism, improve the activity of cell enzymes, improve the nutrition and function of tissues and organs, improve neurotrophic, improve the regulation function of neurohormones, enhance human immunity, and have obvious anti-fatigue and anti-aging effects.
(4) It can enhance physical fitness, prevent diseases and maintain abundant energy.
People's physique is influenced by heredity, nutrition, living environment, living rules and physical exercise. A large number of scientific practices have proved that participating in fitness exercises can enhance physical fitness and improve the body's resistance to the external environment, thus preventing diseases and improving health. At the same time, moderate exercise is also a positive way to rest, which keeps people full of energy and physical strength and improves work efficiency.
(5) The influence of sports on mental health.
A common feature of many centenarians at home and abroad is their love of physical labor and exercise. Although these people have entered old age, their body organs are still relatively young through exercise.
Moderate exercise can not only make the heart and lungs younger and prevent muscle atrophy, but also be an effective factor to make people feel better. Modern physiological and medical research fully shows that happiness, optimism and openness are beneficial to health and longevity; Depression, anxiety and boredom are all harmful to health. A research report from Harvard University shows that unhappy people live much shorter lives than happy, optimistic and happy people.
There are many factors to be optimistic, open-minded and comfortable, pay attention to ideological cultivation, arrange colorful life and handle family relations well. However, it is worth pointing out that regular physical exercise is one of the more effective factors to make people optimistic and happy. Because exercise can not only add fun to the life of the elderly, but also be a good way to prevent and treat depression in the elderly. Dr. Muck in the United States said: "Exercise can enhance people's self-esteem and sense of independence and eliminate depression." People who exercise regularly have this experience: when they come back from exercise, they often have a special comfort. Physiological research shows that sports make the right hemisphere of the brain, which is in charge of intuitive images and music art, dominate; At the same time, it increases the content of neoadrenaline in the brain and excites the sympathetic nerve. All these factors contribute to making people feel happier.
As the saying goes: "Smile, ten years old; I was so embarrassed that my head turned white. "Therefore, the elderly should exercise regularly to keep themselves optimistic and happy.
(6) It can cultivate self-confidence and regulate emotions.
Self-confidence is what people need to maintain in every period, especially in old age. At this time, people's various functions are deteriorating, and they have lost their original vitality and self-confidence in doing things. However, psychologically, everyone subconsciously wants to be taken seriously. Driven by this ambivalence, people will have unstable emotions. As a result, the elderly often have emotional manifestations such as irritability, fear and tension, anxiety and depression. At this time, it is necessary to take certain measures to adjust, and the unique effect of exercise will be reflected. Because fitness exercise can bring youthful vitality to people, make life full of vitality and joy, and make people full of spirit and energy; It can also improve the working ability of human organs, improve muscle metabolism and accelerate the recovery of working ability of tired organs, so people call it active rest. In addition, because fitness activities are all-encompassing, middle-aged and elderly people can freely choose their own sports to entertain themselves, such as walking, doing all kinds of unarmed gymnastics, playing Tai Ji Chuan, playing table tennis, badminton and swimming. In the process of study and practice, I not only exercised my body, but also made friends and improved our communication.
