Why can t sports training be stopped?

Because the body has adapted to this state of exercise, just like people often say to use the brain more, otherwise it will rust, the body adapts to this movement cycle, stop and wait until it is exercised again, the body is difficult to open, so, exercise should be insisted on, not in the amount of exercise in a day, but, let exercise become a habit of life, and you are reading sports, let alone stop... Come on! This is my personal opinion, I hope it will be helpful to you.

Because physical activity is a project that continues to develop. It needs to be accumulated. Be sure to keep it continuous ... You see which championship is not consistent. So to persevere, you have to believe in yourself ...

Sprint technical requirements: loose, big, fast, forward.

Start: Reaction acceleration ability.

Running on the way: The ability to run at a high speed, as well as the quality of the movements completed by the various parts of the body. In a running cycle, there are action phases such as landing, cushioning, back push and forward swing, and taking off.

Back press and take-off: In the landing cushioning stage, when the sole of the swinging leg hits the ground, the landing group rush phase begins, and the foot landing action should be very active, and the landing position is one and a half feet in front of the projection point of the body's center of gravity. After the forefoot hits the ground, the support leg is quickly bent for cushioning due to the force of gravity and the pressure of the swinging leg swinging.

The cushioning of the support leg is not a negative. Instead, you should take the initiative to accelerate the forward shift of the body's center of gravity, and have a downward and backward picking movement. When the body's center of gravity shifts to the vertical ground, the supporting leg joint is at an angle of about 130 140 degrees, the ankle joint is dorsiflexed at an angle of about 85 degrees, and the heel is off the ground, forming a "press and ready" position.

During the cushioning of the support leg on the ground, the swinging leg swings forward quickly in a folded position until it swings slightly in front of the knee joint of the support leg, folding the tightest and the heel almost touching the hip. When the body's center of gravity moves past the vertical plane of the support point, it enters the back push of the kicking leg and the forward swing of the swinging leg. At this time, the swing leg should be in a folded position, and the fold is tight, which is conducive to shortening the radius of the swing leg and speeding up the swing speed.

When the knee joint exceeds the supporting leg, it is quickly and forcefully lifted forward and upward, and drives the pelvis on the same side to send forward, the thigh and the horizontal plane are about 15 20 degrees, and the supporting leg actively cooperates with the swinging leg to quickly and forcefully extend the hip joint, and the knee and ankle joint are extended in turn and pushed off the ground. At the end of the push, the angle between the thighs is about 100 110 degrees, and the angle between the support leg and the ground is about 47 51 degrees.

Vacating stage: The end of the support leg back pedal enters the vacant stage, at this time, the calf that has just finished the kick swings with the inertia of the ground and the thigh and quickly folds closer, forming the action of folding the big and small legs while swinging forward. At the same time, the swing leg is actively pressed down with the hip joint as the axis, the knee joint is relaxed, and the lower leg naturally stretches forward and down with the inertia of the swing leg and thigh down, ready to land.

During the whole run, the athlete's head should be straight, the upper body should be slightly forward, and the arms should swing back and forth quickly and strongly. When swinging forward, it is slightly inward but not over the vertical midline of the human body, the height of the hand does not exceed the lower jaw, and accompanied by the action of sending the shoulder forward on the same side and looking backward on the opposite side, the elbow joint is slightly outward when the arm swings back, the angle between the large and small arms is 60 70 degrees in the front swing, the angle in the back swing is 90 degrees, and the middle is 130 150 degrees in the vertical part of the body. In short, on the way to run requires loose, pedal and coordinate with the pendulum, fold tightly, lift high, and fast, and land actively to have the action of picking up the ground, with a strong swing arm, mental concentration, high emotions, go with the flow, pay attention to practical results.

For senior high school sports students, is it easier to solve it by getting the coach - it's not easier than training by yourself.

Go to the gym or gym to exercise. There are professional coaches to teach. Do not overly force exercise to save the strain of muscles.
