Scientific fitness to avoid the "haze"

In severe haze weather, high-intensity aerobic exercise will be carried out. The amount of air inhaled by the human body will increase significantly, and the inhalation of pollutants will increase exponentially. Not only will it not achieve the purpose of fitness, it will even produce completely opposite effects, causing a certain degree of damage to the body.

Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, said that many years of epidemiological studies have shown that short-term or long-term exposure of particulate matter will have adverse health effects on the human body. Short-term exposure can lead to an increase in the incidence of asthma and acute bronchials, and long-term exposure can lead to adverse health effects on the human body. Including many long-term effects such as decreased lung function and immune function, and increased mortality rate of cardiovascular and cerebrovascular diseases. Among susceptible people, this effect is more obvious.

If fitness exercise is compared to a "protracted war", in the context of air pollution that cannot be eradicated in a short period of time, the strategic and scientific nature of fitness should be emphasized.

Fitness is not only aerobic exercise. Training of strength, flexibility and balance are important contents of fitness exercise. When outdoor air quality is poor, choose to consume low oxygen and strong oxygen indoors. Fitness events with small degree and insufficient lung ventilation can not only achieve the effect of exercise through moderate soothing exercise, but also will not significantly increase the inhalation of pollutants. It is not too late to perform high-intensity aerobic exercise after the weather is good.

Of course, you should also pay attention to avoid "the extreme will turn back" and you should not give up fitness completely because of poor air. After all, only proper exercise can improve the body's resistance and reduce the chance of respiratory diseases caused by air pollution. In schools, other cultural courses cannot be squeezed out for sports activities on the grounds of haze. During the period, when the smog is severe, it is a good choice to let children go indoors for activities or games.

Sports functional departments at all levels in the country also have the responsibility to strengthen the publicity of scientific fitness concepts, especially to pay attention to the corresponding increase in the knowledge of scientific fitness in the training of social sports instructors, so that more grassroots fitness enthusiasts can benefit from it.

Fitness cannot be "the courage of a man", and it is not advisable to give up exercise completely. Scientific planning of fitness content and "staggered exercise" according to the weather is the meaning of actively responding to smog weather.
