Playing football is likely to lead to hypoxia in the brain, causing certain brain lesions and brain injuries, because we will run at variable speed during playing football, that is, we may suddenly run at variable speed while walking, or suddenly brake, because it is very important for our breathing in this process. If our breathing can't keep up with the rhythm, it will probably lead to hypoxia.
When some players play football, they will hold their breath because they are desperately sprinting with the ball, which is actually very harmful to their health. If the brain lacks oxygen, they are likely to faint on the spot.
Running a marathon may also lead to dizziness, which is actually a manifestation of lack of oxygen. Running a marathon is a long-term exercise, during which there are aerobic breathing and anaerobic breathing exercises.
Because when we are running, we need to provide enough nutrition and oxygen for our energetic body. If there is not enough oxygen supply, the blood vessels in our body will not be relaxed, and the blood circulation will not be smooth, which is likely to lead to brain congestion and anemia.
When we run a marathon, we must adjust our breathing and pace according to our breathing. You must not be fast or slow, so that your breathing can't keep up with the pace.
Squat fitness training is very likely to lead to brain hypoxia, because in the process of training, if the breathing adjustment is uneven, it may lead to our inability to adjust our breathing when we take it back or exert force, which is likely to cause brain damage, because oxygen cannot be replenished to the brain in time.
