Can anyone help me explain the pivot foot, the more detailed the better!

After the left foot falls, according to the "rear foot is the center foot principle", the left foot is the center foot foot, and there is no problem with the right foot layup at this time.

If you go to the basket with your left foot, you don't walk if you jump with both feet at the same time.

Generally speaking, the pivotal foot is the foot that does not move and then moves around it when the ball is stopped. The pivot foot is the key to judging whether to walk or not! However, in a game, how do we tell if the pivot foot has moved in a complicated situation?

In basketball, any step action of stopping the ball between marches (catching the ball, stopping the ball by dribbling) can be divided into two types: jumping to stop the ball and two-step stopping.

The difference between them is that when they control the ball (which is important) the foot lands differently, jump stop the ball: both feet land at the same time, and either foot can be selected as the pivot foot;

Two-step stopping: both feet hit the ground successively, only the first foot can select the axis foot;

In particular, it is important to note that they have in common that the ball cannot be caught before the first foot is taken (in the process of reaching out to meet the ball).

This is true for receiving the ball in the middle of the march, and the same is true for the stop of the dribble in the middle of the march! For example, a jump layup is a dribble and stop the ball between the march and a basket.

The difference is: it is not a simple stop of the ball, it is a step to change the direction of travel to bypass the defenders, and the action of the hand is not simply to meet the ball and catch it (you need to protect the ball, you also need to coordinate the body with the movement of the feet, and you also need to prepare for the later shot), but the footsteps and stopping the ball are exactly the same! But it's worth reminding that you must not move any foot after the jump is completed!

Three-step layup, two-step stop ball when the first foot on the ground can't move, but obviously when we go to the three-step layup, we are running, that is, the first foot is moving in the air before the second step lands on the ground (so when the second step lands on the ground, you have to jump, or shoot or pass), and then add the back to jump and shoot, from the point of view of receiving the ball, it is a complete walk, but it is a complete process. This is different from skipping, which is completely in line with the general rules of judging steps.

The judgment of the pivot foot is still very complicated, and you should pay more attention to it in the usual playing process. Especially when practicing new moves, you must not violate this rule. Otherwise, it will be difficult to correct!

This technique is generally applied to the place under the blue or closer to the blue, as follows:

For example, after you hold the ball, your left foot is fixed on the ground, and then your right foot exerts force, and your body even turns left and right to shake in a circle to resist the defense around you to throw blue, and then crash out of the air to complete the blue. Of course, the premise is to be careful not to violate the three-step violation.

We also often see Kobe Bryant use this technique in the middle distance, then shoot blue, and can find the opponent to foul and get a 2+1 opportunity.

I wonder if you're satisfied?

At this time, the left foot is the central axis foot, and moving the left foot is walking. Do you know how to jump to catch the ball. Don't be in a hurry to dribble after receiving the ball, because then both of your feet can be used as the center axis. It is recommended that you get rid of the ball stoppage, and you can only do this with a center under the basket, and it is easy to get close to the ball on the outside.

If there is a stop, the first stop is the pivot foot.

If both feet land at the same time, and before moving, either can be the pivot foot.

Well, but not quite, because if you dribble the ball and both feet don't move, then you stop the ball and both feet can be the center foot.

The one that moves is not the pivot foot, and the other one can't move.

It depends on which way you're going. As long as you have any foot that doesn't move, that's the center foot

When jumping and catching the ball, the one who lands on the ground first is counted as the pivot foot. Also, if you catch the ball on the spot, which foot moves first, the opposite one is the central axis, so if you stay on the spot, it doesn't matter if the other foot moves around.

This song was sung by Mr. Guan Zhengjie, and it was covered by Jacky Cheung in 1984 when he competed and became even more popular. Using the bend of the river to explain his troubles and worries about some problems, the author had to leave his hometown with tears in his eyes, wandering at the ends of the earth, thinking that one of the ten thousand ants was inconspicuous, but it was the only one who left the group, and when he left, he was very depressed, dreaming that if one day he had the ability, he would definitely return to his hometown, the ups and downs of life are very normal, everything in the world is changing, in his dream he still looks forward to this beautiful future, he seems to see the future, But by that time, his sideburns were already white and old.

That's probably what it means.,Ask for points.。。。 Huh

The speed at which the parachute descends has nothing to do with the lines, because the parachute is based on the area of the parachute to achieve deceleration. And the drag force in the air is proportional to the square of the velocity, and the drag coefficient is certain.

The rope length only changes the center of gravity of the entire parachute system, and does not change the cross-sectional area of the parachute, so it will not affect the speed of landing, but the rope length is a little longer, which is conducive to controlling the landing accuracy.

The longer the rope, the shorter the landing time, and the shorter the rope, the longer the landing time. Also, it depends on the size of the parachute.

The more often the rope, the longer it will take to land and the higher the risk.

The shorter the longer, the sooner you learn the compulsory high school course, you will know Heli.
