Sports tabloid content: sit-ups can reduce stomach. There are two views on whether sit-ups can reduce stomach:

Pro-article

Some people think that sit-ups are the most effective way to help women eliminate their stomachs. It is a weightless aerobic exercise, which can not only reduce excess fat and tighten the skin of waist and abdomen, but also benefit ovarian ovulation and intrauterine health care. Moreover, sit-ups mainly practice core strength areas, which can not only exercise rectus abdominis, but also exercise external oblique abdominis and erector spinae of waist and back, which can effectively reduce waist circumference and lose weight.

They even think that sit-ups can burn fat and lose abdominal fat more effectively than other aerobic exercises. So they only choose to reduce the fat in their stomachs by sit-ups, and do a prescribed number of exercises before going to bed every day for a long time.

opposition

However, when some people are keen on doing sit-ups to reduce their stomachs, others raise objections. They think sit-ups have no effect on reducing abdominal fat. Abdominal fat accumulates in that part because there are too many calories. Therefore, the only way to get rid of these fat bodies is to burn calories through a balanced diet and aerobic exercise (such as running, cycling or swimming).

Expert opinion: Correct posture is effective.

Experts believe that sit-ups can reduce your stomach, but the effect is slow, and you have to lose weight slowly. Fat energy in the body needs at least 20 minutes of exercise to be used and burned. But now many people have small stomachs and often can't find time to do outdoor sports, so they choose to do sit-ups at home to reduce their stomachs. And force yourself to complete how many movements in one minute, thinking that this can strengthen the abdomen.

In fact, too fast frequency can't improve the effect of exercise. Doing sit-ups can only avoid affecting the body by slowing down the pace of exercise properly, and at the same time enhance the effect of reducing stomach. At the same time, experts remind that many practitioners' sit-ups are incorrect. If the posture is not correct, the training effect will often be different.

Sports tabloid information: the method of training 100-meter running 1, inertia running

Within the distance of 80~ 100 meters, accelerate running for 20 ~30 meters from the start, and then stop the muscles from exerting themselves actively and passively?

Set a point on the straights on both sides of the track and field, and ask the athletes to run 30 meters at an accelerated speed and then do 20~30 meters of relaxed inertia running, then jog to the corresponding position of the second straights, and then do the same distance of fast running, inertia running or jogging. Jogging time is required to be between 30 and 40 seconds, usually in groups of 3 to 5 times. You can practice 2~3 groups in one class. This method can not only cultivate athletes' relaxation ability and sense of speed, but also improve speed endurance.

Step 3 run back and forth

Athletes first run 60-80 meters at an accelerated speed, then run 20-30 meters at an inertia, and go back and forth once, 5-6 times as a group, with 2-4 groups each time. The interval between each round trip is about 30 seconds, and the rest between groups is 5~ 10 minutes. This exercise can cultivate the athlete's sense of speed.
