All above, we said a lot of benefits of exercise, no doubt sports is beneficial to health. However, the improper movement may also cause exercise-induced diseases, sports injuries, and even lead to sudden death. Studies have shown that Coronary artery disease and unexplained cardiac hypertrophy is the main reason for sudden death of movement, in particular, a higher incidence of the latter.
Caused by the change of blood pressure. Some people, especially patients of coronary heart disease with excessive blood pressure increase during exercise, if exercise stopped,especially sudden stop, blood pressure reduce to a low level, which leads to sudden death.
Suffocating cause. When the over-suffocating, the chest pressure is too high, the excess pressure to left ventricular underfilling, greatly reduce cardiac efficiency, the blood not into tissues and cause sudden death.
