According to the circadian rhythm of the human body, the best exercise time is five o'clock in the afternoon and dusk. At this time, most people's physical strength, flexibility, coordination and adaptability are at their best.
3. Moreover, the sugar in the human body has also increased to the peak. When doing various fitness exercises, there will be no energy metabolism disorder and organ function overload. Therefore, healthy exercise and evening exercise are safer and more effective than morning exercise.
Most people are used to exercising in the morning, because the air is fresh in the morning, which is conducive to accelerating the waste discharge of body metabolism at night.
The shortcomings of morning exercises mainly include:
The sugar content in human liver is the lowest in the morning. Modern health care medical experts have studied the rhythm characteristics of human biological clock. It means that the sugar content in the liver is the lowest in the morning. If people do physical exercise during this time, the energy needed for exercise-sugar will be mainly provided by fat decomposition. After fat enters the blood as an energy substance, the concentration of free fatty acids in the blood increases significantly because the human body cannot effectively use the free fatty acids in it. Due to the decrease of myocardial activity, the toxicity of excessive fatty acids often leads to various arrhythmia phenomena, and even leads to cardiogenic shock and sudden death. For the elderly who are in poor health, it is not worth the loss to consume a lot of fat as the energy for morning exercise.
There is a high probability of heart attack in the morning. Experts have investigated patients with a history of heart disease, and found that the probability of heart attack is three times higher around 9: 00 in the morning than around 1 pm in the afternoon, and the peak of heart attack is a few hours after getting up in the morning. This is mainly because the blood is sticky in the morning and it is easy to form a thrombus.
