有些人在运动中或运动后会出现头晕、饥饿的情况,特别是刚刚加入运动行列的新成员,这些症状更为明显。这是怎么回事呢?其实这不奇怪,这是你体内脏器之间发生了“激烈竞争”造成的。具体说就是,机体的运动系统突然跳出来,毫不客气地抢劫了血中的能量——葡萄糖,而造成血糖突然降低,即“运动性低血糖”状态,致使大脑的能量供应不足,便引起了某些大脑饥饿症状。葡萄糖是人体能量的主要来源,大脑是消耗葡萄糖最多的组织,大脑内不能储存葡萄糖,它需要随时由血糖供应。人在正常情况下,血糖的水平是80~120毫

In fact, this is not surprising, this is caused by the “intense competition” between the organs in your body. Specifically, the body’s movement system suddenly jumped out, unceremoniously robbed the blood of energy - glucose, which led to a sudden drop in blood glucose, that is, “exercise hypoglycemia” state, resulting in lack of energy supply to the brain, It caused some symptoms of brain starvation. Glucose is the main source of energy in the body. The brain is the tissue that consumes the most glucose. The brain can not store glucose. It needs to be supplied with blood glucose at any time. Under normal circumstances, the level of blood glucose is 80 to 120 milliliters
