1, 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, feet standing at hip width. Hands behind your head. Bend forward from the hip joint. Keep your back straight until your biceps feel tense.
2, 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 forward swing direction of the calf should be positive, and the foot should be as forward as possible, and it should not be everted or everted.
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.
3. 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.
Stretch and stretch-sit and stretch your ankles, kneel on the ground, with your hips close to your heels and your upper body upright. Slowly press the ankle until the extensor digitorum and forefoot feel enough tension, then lift the hip and repeat, rhythmically and slowly.
4. 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.
5, 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.
