Whether it is morning exercise or not, the amount of exercise should not be excessive on earth. To one’s health, no matter when people start doing exercise, it is good for them a lot, generally speaking, more time is more exercise and then less time is less exercise, as long as they want to move more or less, it does good to them, though it is only one motion.

Exercise should be in line with one’s conditions and get improved little by little, when people begin doing exercise, they had better get away from drastic exercise, who have to improve the amount of exercise slowly later, it is not simply moving a little that could solve the problem, in order to detect the exercise, apart from knowing it by heart rate, people can learn about it though the method of talking, supposing people gasp too hard to say out anything while they are doing exercise, the amount of exercise has been more than normal amount.

Whatever kind of sport people do, especially to the olds, suits systemic sport from keeping fit, such as swimming, running and walking, they are all good ways to make people stronger, gymnastics is good, too. However, it will always get a definite level, there is a saying of three and seven, so-called three is that the time of each exercise should be more than thirty minutes, if it is within twenty minutes, the intension could not be very large, it only use a few blood sugars, so it can not help people loose weight or expend much fat which has accumulated in body for ages. What needs noticing is not to do exercise immediately people have dinner fully, whose reason is that after people finish eating their blood sugars enter into the stomach to help digest totally.

A study report of Chicago university indicates that the role of biological clock of body to the response to exercise is more important, compared to what people thought in the past, the result may change people’s habits of doing exercise in morning at last. They have done research on the reaction of body to exercise of forty men in one day’s different time whose ages are from 30-year-old to 40-year-old, its result indicates that the response of hormone which is pivotal in body metabolism is intensest among night.

Researcher of Chicago university says that when it is at night the hydrocortisone related to fat metabolism and the thyroid hormone in blood related to muscles repairing are increasing sharply. They give an example that the result of blood testing of doing exercise of high strength on treadmill for an hour indicates that the level of hormone is equal to that of having a rest abed at the same time, however, during the time between night and drawn, the level of hormone will be higher than the others greatly, which suggests that hormone’s reaction to exercise in different time is controlled by biological clock or physiological rhythm. Researchers tell that at present doing a conclusion that the time to do exercise is better than that time is not right, but what surprises us is that hormone’s reaction to exercise should be related to time.
