Why can't football players smoke

summary

My brother likes football very much, and his dream is to be a football player. But he likes smoking very much, and he is addicted to smoking. So why can't football players smoke on the playground? Let's get to know about it next.

Why can't football players smoke

Smoking is harmful to athletes. First, smoking reduces the lung ventilation. The maximum oxygen uptake is determined by the levels of inhaled oxygen, transported oxygen and utilized oxygen. The lung ventilation is a component of inhaled oxygen. Because smoking will increase the resistance of respiratory tract and affect the air volume in and out of the lung, it will inevitably affect the maximum oxygen uptake by inhaling oxygen, which will lead to the decrease of exercise ability.

Smoking is harmful to athletes. Second, smoking makes hemoglobin absorb oxygen. After oxygen diffuses from alveoli to blood, it is mainly combined with hemoglobin in red blood cells and transported to various organs and tissues. Because the inhaled smoke contains carbon monoxide, and its binding ability with hemoglobin is several times stronger than that of oxygen, it will inevitably lead to the reduction of the binding amount of hemoglobin and oxygen, so it will make the athletes feel better The maximum intake was also affected.

According to scientific measurement, the respiratory resistance of long-term smokers is twice as large as that of non-smokers. If they stop smoking 24 hours before exercise, the respiratory resistance will be reduced, and even non-smoking on the same day will contribute to the recovery of competitive ability. So we need to stop smoking, and athletes should not smoke.

matters needing attention

Swallowing should not be advocated for ordinary people or football players. The difference is that ordinary people are not encouraged to smoke just for the sake of health. For football fans, there are also factors to improve their sports ability and competitive level. The most direct harm of smoking to the improvement of football players' competitive level is that it makes the maximum oxygen uptake, a typical index of aerobic endurance (general endurance), decrease.
