Preventive measures. Prevention of curling injuries need to start from 3 aspects of technical movement improvement, physical quality training and adequate preparation activities.
(1) Technical movement improvement. Technical movement improvement is to enable athletes to understand the characteristics of the completed technical movements and the body's anatomical structure, you can use Poser software to create a variety of easy to lead to injury and incorrect technical movements, the formation of a good visual animation or frame-by-frame demonstration of the effect of sports injury simulation of the three-dimensional image, in order to assist the coaches and athletes to understand and recognize. In the technical aspects where there is a risk of injury, it is necessary to improve the movement or adopt the means of preventing injury, such as support belt, muscle effect patch, etc., to eliminate the biomechanical mechanism that causes injury as much as possible.
(2) Physical training. Physical quality training needs to improve the speed, strength, endurance, flexibility and balance required for curling program, so as to ensure that the athletes in the game effectively use the techniques and tactics to achieve excellent results. Attention should also be paid to the athlete's off-ice condition, strength and flexibility, control techniques, psychology and other aspects of training, in order to enter the season training to lay a good foundation.
(3) Adequate preparatory activities. For athletes, should improve the awareness of self-prevention, before training in the ice rink adaptive practice and familiar with the site; fully prepared for the activities, preparatory activities to be divided into land preparatory activities and ice special preparatory activities. Land preparation activities is the athlete in the training before the body in the race cold environment to get a comprehensive warm-up, mainly including body flexibility training, pulling exercises and PNF (proprioceptive neuromuscular facilitation method) exercises and so on. Ice-specific preparatory activities should be more ankle, knee, waist and back, shoulder, elbow, wrist stretching exercises, to avoid sports injuries due to inadequate preparatory activities. The amount of exercise in the preparatory activities should be as good as the body heating without sweating. Specifics developed by domestic curling experts include: strides, which are designed to raise body temperature and improve heart function for 5 minutes, wearing clothing suitable for doing strides. Choose a slight, rhythmic aerobics, followed by holding a brush low leg lift, holding a brush with both hands and lifting it flat to the front of the abdomen low leg lift, brush height gradually increase high leg lift; stretching, the purpose is to lengthen the muscles so that the body is flexible, the time 10 minutes, pay attention to the location of the stretching, the feeling, the time and the order. Wrist stretches require fingers upward, chest closed palm, will both hands at the same time to the left or to the right side of the flexion, for 5 to 10 seconds, there is a sense of compression until. Upper arm and shoulder stretches require one arm to be chest flexed and the other forearm to be stretched inward for 5 to 10 seconds, alternating between the two arms for 2 to 3 times. Shoulder stretch requires both arms to be bent flat on the chest with the forearms close to the body, forcefully expanding the chest and stretching for 5 to 10 seconds. Thigh stretch requires kneeling, legs apart calves touching the ground, upper body gradually backward, stretching the ankle joint and quadriceps, stretching 5 to 10 seconds. Calf stretch requires standing against the wall, legs open front and back, full feet on the ground, bend the knee joint of the front leg to stretch the calf area of the back leg, stretch for 5 to 10 seconds. Waist stretching requires hands on the ground, lower limbs touching the ground, the body is reverse arch, the waist as much as possible to touch the ground, hip tightening, stretching 5 to 10 seconds. The leg press requires a seated position, one leg extended forward, the other leg flexed, the body flexed forward, the chest and head touching the leg and foot as much as possible, a stretching sensation at the waist and knee, stretching for 5 to 10 seconds; the skate, the concluding part of the preparatory activity, is performed on the ice in a mimicry of a potting and sweeping motion, which can be impressed on the athlete with a video or music. Athletes in the practice of the beginning of the stirrups out, with a small force can be maintained in a higher part of the body posture, and gradually transitioned to the use of full force stirrups out, sweeping the ice when the power and amplitude should follow the principle of from small to large, step by step.
4. Although the curling program has the above risk factors leading to sports injuries, but compared with skiing, ice hockey, speed skating and other winter sports, is still a safer sport. The project started late in China, the current athletes under the age of 20 years old men's team accounted for 60.71%, women's team accounted for 76%, showing the characteristics of China's project team members younger, may be temporarily no sports injury problems plagued by the problem, but professionals should be grasping the technology, tactics and management at the same time to learn from foreign countries for the project injury prevention and treatment of the experience of the importance of curling sports injury research. Strengthen the injury and illness reporting system and establish a complete medical record system to provide effective information for improving medical quality and experience accumulation. At the same time, in the national team and provincial and municipal training teams to strengthen medical supervision, equipped with the necessary medical equipment and adequate medical personnel, training team doctors carefully observed, found that the injury potential hazards, such as venues, equipment, protective gear and other issues in a timely manner to exclude, correctly deal with the training and competition in the emergence of acute and chronic injuries, for the athletes to recover in time to create good conditions.
