Summer is coming, and people's enthusiasm for fitness is high. All parties need to make joint efforts to provide more targeted scientific fitness guidance services, so that people can reap health and happiness in physical exercise. Summer is coming, and people's fitness enthusiasm is high. They can walk on the footpath and the stadium and sweat freely. People are willing to overcome the high temperature and actively participate in fitness, which is the embodiment of the in-depth development of national fitness and the deep penetration of health awareness. "Three nine in winter and three volts in summer". Research shows that physical exercise in summer can increase body consumption and enhance the functions of digestive, respiratory and endocrine systems. However, many bodybuilders also have some misconceptions, thinking that "not sweating is equal to not exercising" and "sweating more can better achieve the goal of fitness". In this regard, sports experts have repeatedly called on people to pay special attention to grasping the scale in summer fitness. Exercise should be carried out according to one's ability. In summer, the temperature is high, the water loss of the body is fast, and excessive exercise has the risk of heatstroke, which is easy to cause fatigue and even sports injury. Therefore, to participate in fitness exercise and enjoy sports fun in summer, it is necessary to be gradual and relaxed, and adopt scientific and reasonable fitness methods, so as to achieve the effect of physical exercise and pleasure. For example, take short and low-level exercise to gradually adapt the body to the hot weather; Avoid outdoor sports during periods of strong sunshine; The whole day fitness plan can be completed in sections and times; Pay attention to warm-up and water replenishment before and after exercise... Many precautions need not only the fitness personnel to strengthen their self-protection consciousness, but also scientific and reasonable fitness guidance. People's enthusiasm for fitness is high, which means there is more demand for scientific guidance. Some localities and departments have made explorations in many aspects. The series of short fitness videos "scientific fitness 100" and "scientific fitness week" launched by Jiangsu Sports Bureau and Jiangsu Institute of physical education have accumulated 80 million hits over the past year; The Beijing Social Sports Management Center launched a series of scientific fitness online guidance, with a total of nearly 4.3 million course views; The national intelligent community AI fitness conference led by the mass sports department of the General Administration of sports of the people's Republic of China was launched on June 10. It launched 6 online projects emphasizing scientific fitness, such as spine and vision health parent-child exercises, to provide fitness guidance for the masses. People's fitness needs are increasingly diversified. All parties need to work together to provide more targeted scientific fitness guidance services, so that people can reap health and happiness in physical exercise. (outlook new era)
