What are the classifications and principles of sports injury prevention?

The industry generally divides sports injury prevention into three-level prevention and control logic. The implementation core focuses on three directions: function priority, individualized adaptation, and full intervention, which can cover more than 90% of sports scene risks.

The most upstream primary prevention is aimed at uninjured people, mainly to check for potential risks, correct wrong movements, and establish a sports foundation. When I led the high school men's basketball team for training two years ago, more than half of the children who just joined the team had problems with foot pronation or insufficient core strength. When I was playing field ball, my intensity was low and I didn't feel it. When I jumped a lot in the competition, sprained feet and waist flashes were common. Later, when I joined the team, I did a gait assessment and basic strength screening, targeted changes in jumping and landing movements, and core training. The acute injury rate throughout the season was directly reduced by 60%.

The next level of secondary prevention is for people who have already had acute injuries. The core is to avoid the recurrence of old injuries and prevent mild cases from turning into chronic ones. Just like the children with sprained feet just mentioned, they cannot be returned to the playing field directly after the swelling subsides. They must first supplement the strength and proprioception training around the ankle. If you cannot stand firmly on the balance mat, start with wall exercises. Otherwise, it will easily become a habitual sprained foot, and it will be difficult to adjust it later. The final level of tertiary prevention is for people who already have chronic sports injuries, mainly to control the progression of the injury and avoid affecting normal sports and life. Many old runners who have been running for more than ten years have patellofemoral pain, which cannot be completely cured. They have to control the running volume, actively increase the strength training of the gluteal muscles and quadriceps, and put on muscle effect tape before the competition, which can greatly reduce the frequency of pain attacks and avoid further wear and tear of cartilage.

After knowing the logic of classification, when it comes to daily exercise, you must adhere to a few core principles, otherwise it will be easy to make useless efforts or even cause trouble.

The first thing to understand clearly is the bottom line of giving priority to function. All preventive measures are to enable you to exercise for a long time and healthily, not to meet the training KPI. I met a young man in the running group last week. In order to reach the goal of running 200 kilometers, he still had to run a half marathon with a faint pain in his knees. It was originally just a small problem of muscle tension, but eventually the patellar tendon became inflamed. After two months of rest, it did not heal completely. It was completely worth the loss. As for the current hotly debated question on the Internet about "should you do static stretching before exercise?", it actually revolves around function. Some studies believe that static stretching will reduce muscle explosiveness and is more suitable for doing after exercise. There are also clinical data showing that for people with particularly poor flexibility, short-term static stretching combined with dynamic warm-up can actually reduce the risk of muscle strain. There is no standard answer. It depends on what makes you comfortable and in good condition when exercising.

In addition to giving priority to functions, the most easily overlooked thing is individualized adaptation. Many people follow the trend and buy Internet celebrity protective gear and copy other people's training plans. In the end, they are easily injured. I met a fitness enthusiast before and watched others wearing knee pads to do heavy squats. He had no knee problems and sufficient muscle strength. After wearing the three-month knee pads, his quadriceps strength dropped. He took off the knee pads and squatted with his own weight. Feeling that your knees are weak is a typical sign of not understanding the adaptability - protective gear is originally used as an auxiliary for people recovering from injuries or those with insufficient strength. Long-term wearing of healthy people will cause muscle dependence and increase the risk of injury. Just like some people wear cushioned running shoes to feel comfortable while others wear supportive models to avoid sprained feet. There is no universal prevention plan, and you have to adjust it according to your own physical condition.

Another very important point is that prevention is not just a 10-minute warm-up before exercise, it must be a full-scale intervention. I used to have a fitness friend who stayed up late and worked a whole night shift. The next day, he insisted on going to the gym to do heavy bench presses. He was not paying attention and directly strained his shoulder. If he had changed to light weight that day, There is nothing wrong with aerobic exercise or simply resting. Many people have a too narrow understanding of prevention. Relaxation after exercise, daily strength recovery, proactively reducing intensity when physical condition is poor, and even sitting in the office without crossing your legs to avoid pelvic tilt affecting force production are actually part of sports injury prevention.

In fact, when it comes down to it, sports injury prevention has never been a profound academic topic. It just means paying more attention to your body's signals. Don't force yourself to do it, and don't follow the trend. It is more effective than any fancy equipment.
