Recently, a report about a man's old knee while practicing spinning has spread all over the country in an instant. So many people have thought about which sports are easy to get hurt. But in fact, as long as you exercise, you will get hurt. The only way to prevent it is to warm up before exercise. Let's refer to the specific case analysis.

Losing weight is a hot word on the Internet in today's era. Nowadays, both middle-aged and young people will attract strong attention. However, just two days ago, a middle-aged man in Xi 'an did a series of exercises because he didn't reach his weight. For example, spinning bike, which is well-known in the weight-loss circle, attracts many dieters because of its strong fat-reducing ability.

The middle-aged man in Xi 'an mentioned just now is the following one. Mr. Huo, 45, has always been overweight. The physical examination report showed that a large number of indicators were unqualified, moderate fatty liver, high blood pressure and high uric acid, so the doctor gave him a death order and had to lose weight. Later, under the guidance of a fitness instructor, Mr. Huo rode a spinning bike for 40 minutes every night, and lost eight pounds in a month.

But a month later, although Mr. Huo became lighter, it became very difficult to go up and down the stairs. So Mr. Huo went to the local hospital for examination and found that the whole cartilage surface of his knee joint was completely worn. This month is equivalent to the wear and tear of joints under normal use for more than ten years. Now Mr. Huo's knees are as worn as those of a 60-year-old man.

A similar thing happened in Wuhan last year, in September 2020. Xiao Wang, 28, has always been a bit "rich". Because I was dissatisfied with my body shape and worried that it would be harmful to my health, I came up with the idea of exercising to lose weight. I heard that spinning is a good way to "burn fat and throw meat", so he went to a gym to hold a group class of spinning and sweated under the guidance of the coach every day after work.

Unexpectedly, just after a week, Xiao Wang's knee began to hurt and he hasn't lost weight. Not to mention continuing cycling, even simple squats and going up and down stairs are difficult. Unable to lose weight, he quickly went to the Fourth Hospital of Wuhan for treatment.

On September 27th, 2020, Xiao Wang was diagnosed with chondromalacia patellae in the Department of Rehabilitation Medicine. Fortunately, Xiao Wang's knee injury is not serious at present. After receiving a series of physical therapy and oral anti-inflammatory and analgesic drugs, Xiao Wang's knee pain has been greatly relieved. The doctor also told Xiao Wang that in the later stage, some muscle stretching on the front thigh and muscle exercise around the knee joint can be properly carried out to strengthen the protection of the knee joint, which can effectively prevent recurrence.

Among them, Xiao Yan practiced yoga at home in Tamia Liu's recently hit TV series Dear Love, hoping to relieve depression through exercise. However, Xiao Yan is a little overconfident about his motor nerves. Do not exercise for a long time, flash to the waist when standing upside down, and stand on the wall without moving. The netizen shouted, "I seem to be hurt by the true feelings."

As a girl who lives alone, Xiao Yan is helpless and can only cry for help from her competitors who live across the street. She poured out her grievances and dissatisfaction to Chen one by one. In order to be rescued as soon as possible, Xiao Yan raised the national flag loudly. "Chen, if you call an ambulance for me today, I'll forget my enmity with you!"
