Not sitting down immediately after running can cause some harm to the body

Running is an aerobic exercise that is very beneficial to the body, but some new runners often sit down immediately because the body is tired after running. This kind of behavior is wrong and may cause some harm to the body.

Zhang Yimin, a professor at the Key Laboratory of Sports and Physical Health of the Ministry of Education, Beijing Sport University, said that when people run, due to gravity will lead to congestion in the lower limbs, and to return the lower limb blood to the heart in time, mainly rely on the contraction and relaxation of the lower limb muscle group, squeezing the blood vessels to return the blood to the heart. If you sit down immediately after running and rest, it will cause the lower limb muscles to relax, lose the squeezing effect, make blood stasis in the lower limbs, cause the brain to temporarily lack of blood supply, appear pale, lips purple and other manifestations, and even faint in serious cases, which is medically called "gravity shock".

In addition, sitting down immediately after running can lead to congestion in the lower extremity muscles, making the lower extremity temporarily coarse, which can usually be improved after sleeping.

In short, in order to prevent adverse consequences such as "gravity shock" after running and speed up the dissolution of acidic products in the body, it is necessary to pay attention to the following matters: fast runners need to slow down the running speed when they are about to end, continue jogging for a while, and do some stretching actions and take deep breaths until they feel comfortable. Whether you're running fast or jogging, stretch well after your run. For example, thigh stretching: stretch the leg backwards, the sole of the foot up, the same side of the hand to hold the ankle, close to the hip, so that the front side of the thigh stretch; Calf stretching: stretch the legs and feet on the auxiliary object, with the auxiliary object as the fulcrum, the toes as far as possible, the heel landing, the body can slightly lean forward, feel the calf stretch. Do at least 2 sets of stretches for about 20 seconds each.

A joint study by the University of Bath and the University of Birmingham found that by adjusting the order of meals and exercise, overweight people can better control their blood sugar levels.

Exercising before eating helps control sugar

The research team took 30 overweight or obese men and asked them to take part in a six-week trial. One group exercised before eating breakfast, and the other exercised before eating breakfast. Both groups exercised the same amount and ate the same amount of food. A control group made no lifestyle adjustments (such as not exercising at all or skipping breakfast). The results showed that participants who exercised before breakfast burned twice as much fat as those who exercised after breakfast. The increase in fat consumption was mainly due to lower insulin levels during exercise after fasting overnight, which meant that participants needed to consume more fat tissue for fuel. In addition, those who exercised before the meal had more key proteins in their muscles, particularly those responsible for transporting glucose from the blood to the muscles. As a result, their muscles are better able to respond to insulin, which helps keep blood sugar levels stable. The findings were published in the Journal of Clinical Endocrinology and Metabolism.

The researchers said there was no significant difference in how much weight the two groups lost over the six-week period, but the order of eating and exercising had different effects on their overall fitness. After an overnight fast, exercising before eating can increase the health benefits of exercise.
