A team of Japanese medical researchers headed by Lin Chunyi, an assistant professor at Xinglin University in Tokyo, said that jogging in the evening is better than morning and afternoon. This is their conclusion after jogging time series test for eight men aged from 24 to 28 from 7: 30 am to 5: 30 pm.
They believe that jogging in the morning may cause blood clots and promote heart failure, while jogging at night may reduce the tendency of blood clots and prevent heart failure.
What are the benefits of running?
Long-distance running to prevent arthritis
Sticking to long-distance running may prevent arthritis. This is the conclusion reached by American scientist Shylock after observing the knee joint of marathon runners with the help of magnetic resonance imaging equipment.
Shylock found that even after running for tens of kilometers, athletes rarely had abnormal cartilage tissue and edema. On the contrary, some recreational long-distance runners will have these physiological changes in their knees after running for 30 minutes. It is speculated that "better biomechanics" and the adaptability of the body through long-term training enable marathon runners not only to run long distances, but also to maintain healthy and strong knee joints.
Jogging can strengthen bones.
Experts from the Medical College of Chiba University in Japan believe that jogging can make bones "young". Four/kloc-0 members aged 30-80 from three jogging groups in Chiba County and 86 men and women who don't like sports at ordinary times were comparatively examined in the hospital. The results show that the bone mineral density of the joggers' vertebrae, femoral joints, leg bones and arm joints is about 40% higher than that of those who don't exercise. This kind of bone density is close to the bone state in the twenties.
As far as men are concerned, the longer jogging time in a week, the higher bone density; For women, bone mineral density is directly related to the length of jogging history. Only those who insist on jogging can achieve the same effect as young people's bone density.
A New Theory on the Disadvantages of Morning Running
Some people wake up early and get up early in the morning, and like to go outside to exercise at dawn. Some go to the park, others go to the roadside Woods to do various exercises or run. They think that the air in the garden in the morning is fresh and dust-free, which is good for health.
However, getting up in the morning to exercise is not good for the elderly or people with poor heart function. Medical statistics show that morning is not only the peak time of heart attack, but also the time of sudden death, with an incidence rate of 6 1. 3%。 Yantian, an associate professor of exercise physiology at Yamaguchi University in Japan, pointed out that jogging in the morning will put a lot of pressure on the heart, because the heart usually cannot adapt to the complete exercise in the morning. Yantian also said that jogging stimulates the body to secrete a lot of hormones, which makes the heart beat faster. The results of his experiments on several female college students show that the adrenaline secreted by morning runners is two to four times higher than that stimulated by jogging in the afternoon or evening.
It can be seen that morning running is not the best choice, and the best running time should be in the evening and jogging, so as to achieve the best exercise effect.
