When the weather gets hot, does physical strength drop quickly during exercise? why
When the weather gets hot, physical strength will indeed drop faster during exercise. This is mainly because when the weather is hot, the human body needs to dissipate heat, the blood vessels on the body surface will expand a lot, the skin blood flow will increase, and the muscle blood flow will decrease relatively, resulting in a decrease in muscle contraction ability. At the same time, the increase of blood in the skin will reduce the amount of blood flowing back to the heart, accelerate the heart rate and decrease the contractility of the heart. Under the action of these comprehensive factors, people will feel more tired during exercise and fatigue will come earlier. Therefore, when the weather is hot, we'd better choose a cool time to exercise in the morning and evening, appropriately reduce the intensity of exercise, jog less, replenish water in time after exercise, and drink some sports drinks during long-distance running.
