Excessive exercise in the five forms of damage to the body — people.com.cn Health Channel – people.com.cn original title: excessive exercise in the five forms of damage to the body. We all know that moderate exercise is good for health, it can reduce weight and reduce people suffering from various diseases, such as Alzheimer’s risk. Taking into account the irresistible, exercise benefits obviously, if we want to live a healthy life, you need to keep physically active. However, the more exercise, the better we are, is it? No. In some cases, exercise can go too far; the body will tell you when to exercise enough. Previous studies have found that long-term endurance training such as marathon, Triathlon and long distance bicycle race, will have a negative impact on cardiovascular health. For example, after a group of patients who had been diagnosed with coronary artery disease underwent a maximum of 60 minutes of recommended exercise, their antioxidant capacity decreased and the blood vessels became stiff. At the same time, those who exercised for 60 minutes or less reduced the number of free radicals in the body, which improved their circulatory function. A medical media in the United States recently summed up five different signs of overtraining. A change in heart rate changes will occur in the heart of an athlete, which can lead to heart related health problems. The study of exercise physiology found that athletes who are engaged in endurance events have a high rate of myocardial fibrosis, especially their heart cells. This hardening caused cardiac arrest, causing arrhythmia. Runners who run more than 25 miles (about 40 kilometers) a week are at risk of dying from those who don’t exercise. Two, musculoskeletal changes in the course of the exercise, muscles and bones will inevitably be damaged, they need 24-48 hours of rest to fully recover. If the muscle fatigue is more than 48 hours, which means that the physical function of the exercise was over challenged, but also shows that his muscles and energy storage is not effectively restored. Researchers at the Johns Hopkins University School of medicine say that chronic fatigue after exercise suggests that the exercisers are over trained. Three, the immune system to change the excessive exercise will damage the immune system function, because the body needs to struggle with fatigue and lack of muscle recovery. Studies have shown that more than 90 minutes of high-intensity endurance exercise will allow athletes to exercise within the next hour after the end of the disease is easy to get sick, because the strenuous exercise will temporarily reduce the function of the immune system (). Four, hormone change training will affect hormone secretion function. Players will experience an increase in cortisol and adrenaline secretion, these two hormones are also known as stress hormones, which can increase the level of high blood pressure and cholesterol, thereby inhibiting the immune system function. Overtraining also suppresses appetite by increasing the secretion of two hormones, adrenaline and norepinephrine. Calorie intake, will slow down the recovery rate, so that the symptoms of overtraining is more serious. Five, sleep change excessive exercise will put pressure on the body,相关的主题文章:
