The essentials of running-keep your head and shoulders stable. Keep your head forward. Don't lean forward unless the road is uneven. Keep your eyes on the front Relax your shoulders properly and avoid having a chest.
Strength stretch-shrug. Relax your shoulders and droop, then shrug your shoulders as much as possible, stay for a while, and repeat after restoration.
2. Arms and hands
Essentials of running action-the swing arm should move back and forth with the shoulder as the axis, and the range of left and right movement should not exceed the midline of the body. Fingers, wrists and arms should be relaxed, and the elbow angle should be about 90 degrees.
Strength stretching-elbow lifting and swing arm. The arms are in the ready-to-start posture, the elbow joint of the rear swing arm is raised as much as possible, and then the forward swing is relaxed. With the acceleration of the action, it is raised higher and higher.
3. Trunk and buttocks
Running essentials-keep upright from neck to abdomen, instead of leaning forward (unless accelerating or uphill) or leaning back, which is beneficial to breathing, balance and stride. Don't shake your torso from side to side or fluctuate too much. Actively send your hips when your legs swing forward, and pay attention to the rotation and relaxation of your hips when running.
Strength stretching-lunge leg press. Separate your legs back and forth, shoulder width apart, and slowly press down on the center of your body until your muscles are tense, then relax and recover. The torso remains upright all the time.
4, waist
The essentials of running action-keep your waist naturally upright, not too straight. The muscles are slightly tense, so keep the trunk posture and pay attention to buffering the impact of the foot landing.
Dynamic stretching-flexion and extension. Stand naturally, feet apart, shoulder width apart. Bend your torso forward slowly until your hands hang down to your toes, and keep it for a while before recovering.
5, thighs and knees
The essentials of running action-thighs and knees push forward, not up. Any lateral movement of the leg is unnecessary, and it is easy to cause knee joint injury, so the front swing of the thigh should be positive.
Dynamic stretching-front bow. Stand with your feet as wide as your hips. Put your hands behind your head. Bend forward from the hips. Keep your back straight until your biceps feel tense.
6, calf and achilles tendon
The essentials of running action-the foot should fall about a foot in front of the body, close to the center line. Don't cross the calf too far, so as not to strain the achilles tendon due to excessive stress. At the same time, we should pay attention to the cushioning of calf muscles and achilles tendon when landing, and the calf should actively scrape the ground backwards when landing, so that the body can actively move forward. In addition, the calf should swing forward, and the foot should move forward as far as possible, and it can't be everted or everted, otherwise it will easily damage the knee joint and ankle joint. You can check your footprints when running on the beach for reference.
Dynamic stretching-supporting heel lifting. Stand facing the wall for about 1 m, stretch your arms forward shoulder width, and hold the wall with both hands. Raise your heel and then put it down. Feel the tension of calf and achilles tendon.
7. Heels and toes
Essentials of running action-If the stride is too large and the calf stretches too far forward, it will follow the ground with its feet, resulting in braking reaction, which is very harmful to bones and joints. When landing correctly, land with the middle of the sole of your foot, so that the impact force can quickly spread to the whole sole.
Strength stretching-sit down and stretch your ankles. Kneel on the ground, keep your hips close to your heels and keep your upper body upright. Slowly press down on the ankle until the extensor digitorum and forefoot feel enough tension. Then lift your hips. Repeat. The movements should be rhythmic and slow.
Anyone who participates in fitness running should pay attention to the law and step by step, especially to control the amount of exercise. In addition, learning "self-control" is particularly important. Because sometimes the desire to run suddenly disappears, it is necessary to distinguish between "unable to run" and "unwilling to run". Of course, if you are sick, you must never run, but in other cases, you should overcome "inertia" and keep exercising.
At the beginning of exercise, the speed of running is limited to no uncomfortable feeling, and the distance of running is appropriate to have no hard feeling. Muscle pain in lower limbs may occur after running, which is a normal reaction, and this phenomenon will disappear after a few days of persistent exercise.
In order to determine your exercise level, you can do some tests after running for three to four months, and the starting point of calculating the level is 12 minutes.
For people aged 30-39, the running distance of 12 minutes is less than 1.5- 1.8 km, which indicates that the sports level is poor. If it can reach 1.8-2.6 km, it means that the sports level is good; If it can exceed 2.6 kilometers, it will reach the excellent sports level.
For people aged 40-47, people with poor sports level run within 12 minutes; Ok1.7-2.4km; Excellent over 2.5 kilometers.
Poor, good and excellent people over 50 years old run within 12 minutes, 1.5km, 1.6-2.4km, and more than 2.5km. ..
Don't fantasize about achieving ideal results in a short time, only regular exercise will improve the level of exercise. If you only run once a week, long-distance running will not do you much good. Because in the six days after the interruption of running, the body tissue has consumed all the benefits brought by running. Therefore, run at least three times a week. People who usually lack exercise, once they make up their minds to start regular exercise, often exercise too much, which will lead to bad consequences. Physical exercise should be gradual, and the following items should be recorded in the diary every day:
1, the nature, content, duration and time spent in each exercise;
2. Self-feeling before, during and after exercise;
3. Appetite and sleep status;
4, whether there is a desire to continue to participate in exercise;
5. Pulse is beating.
According to the above records, it is not difficult to analyze the amount of exercise and make necessary adjustments to the exercise in time. Generally speaking, the pulse rate should not exceed 120 beats/min after running for 5 minutes and 100 beats/min after running for10 minutes. If the pulse rate is too high, you must reduce the amount of exercise.
