一个人记忆力的好坏取决于大脑。脑组织对氧最敏感，它要消耗人体需氧量的 1/4。脑疲劳与缺氧有关，而氧的运输靠血红蛋白 (Hb)。那么是否可以通过适宜运动负荷的体育锻炼来提高血红蛋白的含量，使脑得到充足的氧和营养物质，以消除疲劳，提高学习效率呢 ?我们就此对 200名大学
The quality of a person’s memory depends on the brain. The brain is most sensitive to oxygen, which consumes ¼ of the body’s oxygen demand. Brain fatigue and hypoxia, and oxygen transport by hemoglobin (Hb). Is it possible to improve the hemoglobin content through physical exercise that is suitable for sports load so that the brain can get enough oxygen and nutrients to eliminate fatigue and improve learning efficiency?
