From the perspective of basketball, the special qualities of basketball players include:
First, agility: such as turning back, stepping sideways, sliding, etc.
Second, speed: short-distance running such as 30m, 100m, 400m, etc.
3. Bouncing ability: vertical jump, run-up touch height, standing jump, standing three-step jump, cross jump, etc.
Fourth, flexibility: flexion before sitting, flexion before standing, etc. ;
5. Cardiopulmonary endurance: 12 minutes running, 1500m running, etc.
Muscle endurance: arm endurance, abdominal endurance, foot endurance, etc.
Seven, coordination: hand-eye coordination.
Therefore, if you add all the basic movements of basketball, such as individual offensive dribbling, throwing (throwing) the basket, passing, footwork and defensive sliding, blocking, helping to restore, etc. And the team's offensive actions, such as combining inside and outside, filling position, giving and leaving (cutting), cutting and passing, etc. , as well as defensive movements and ideas, how can jumping ability rank among the top ten important conditions of basketball?
Excuse me, what is walking? I think the NBA thinks that some players take a lot of steps in the layup ~ but the referee didn't blow it. I want to clarify this concept; Also ~ If I break to the right ~ The ball was in my left hand ~ When I break, my left foot pushes hard ~ The ball passes from the left to the right ~ My left foot passes the defender and passes to the right ~ At this time, I continue to push ~ The ball is still in my hand when my right foot takes a step forward ~ I missed it. After landing on the right foot, take the ball with both hands ~ take another step on the left foot for layup. Is there a step in this action?
Basically, you should first understand the definition of a rule, as follows:
Rule 25: Follow the ball.
25. 1 definition
25. 1. 1 Walking with the ball means that the players in the court illegally move one foot or two feet in any direction while controlling the live ball.
25. 1.2 Rotation refers to the legal action that a player stands on the ground with one foot as the center and the other foot steps out in any direction for one or more times, and the so-called center foot always keeps in contact with the floor at the origin.
25.2 regulations
25.2. 1 The center foot of the player who catches the live ball on the court is established as follows:
Catch the ball with both feet on the ground: when one foot leaves the ground, the other foot is the center foot.
◎ Catch the ball while moving or dribbling:
-If one foot touches the ground, it's the center foot.
-If both feet touch the ground, the player touches the ground at the same time. When one foot leaves the ground, the other foot is the center foot.
-If both feet are off the ground, the player touches the ground with one foot, which is the center foot. If a player takes off with this foot, and then both feet land at the same time, neither foot is the center foot.
Therefore, as explained in 25. 1.2, the action you described in the first half does not constitute walking; But when you mentioned that your right foot landed and your feet held the ball, this action lacked the narrative of catching the ball (that is, catching the ball according to the rules). Therefore, I can't judge the timing of your catch from here, and of course I can't judge whether you are walking or not.
Lao Xu, how do you exercise your jumping ability?
There are many ways to exercise your jumping ability, such as using the weight training of instruments (weights), or using the constant speed (or isotonic) weight training of instruments (weights) with electronic devices; The third is unarmed isometric muscle strength training, the fourth is unarmed isotonic circulation muscle strength training, and the fifth is to enhance explosive power training with equipment. The above training, as long as you are intentional, can improve your jumping ability. But as I said before, as far as basketball is concerned, bouncing ability plays an important role in basketball, which is not in the top ten items at all, so concentrate on strengthening basic movements or group offensive and defensive movements and concepts!
I want to ask, how to practice the coordination of the whole body and which parts of the hand need to touch the ball when shooting, and which parts can't touch the ball!
First of all, there is a problem that the palm can't touch the ball when holding it, that is, some fingers can touch the ball, but the ball can't be buried in the palm, and the fingers stick to the ball and can't hold the ball in the air; Secondly, there are many methods of movement coordination, which are described in detail below.
When talking about coordination, we need to understand: 1, the factors that affect coordination; 2. The theoretical description of coordinated training is as follows.
1, factors affecting coordination
The factors influencing coordination are:
(1) interactive inhibition-inhibition or prevention of nerve impulses that dominate the muscles of the opposite side.
(2) Strength-relaxation and contraction of negative muscles.
(3) The appearance of endurance fatigue has an influence on fine movements.
(4) Mental exercise-Mental exercise can improve mental concentration.
(5) proprioception-the tension of muscle joints in position.
2. Coordination training theory.
Coordination means that the body acts on muscle groups at the right time, in the right direction and speed, with stable balance and rhythm. Among all physical abilities, coordinated training is the most difficult, because besides heredity and athletes' psychological character, there are muscle strength and endurance, proficiency of technical movements, the relationship between speed and endurance, balance of body center of gravity (which is related to muscle strength and endurance), rhythm of movements (which requires skilled technical movements), relaxation and contraction of muscles, and even softness.
There are about nine ways to coordinate training: 1, various physical exercises that are not used to movements; 2. Complete the action in reverse; 3. Change the pace and rhythm of your habits; 4. Complete complex actions with the help of games; 5. Require creative changes in the way of completing actions; 6. Use unaccustomed combined movements to make the mastered movements more complicated to practice; 7. Change the scope of the action space; 8. Use all kinds of instruments or natural environment to do all kinds of complicated exercises; 9. Timely use signals or conditional stimuli to make athletes do various exercises to change their movements.
The frequency of coordination training at the grassroots level is higher. Of course, if a person is more than two meters long, the movements are still uncoordinated and the frequency is higher. In the preparation period, the frequency is preferably two or three times a week, with at least ten movements, and each movement is practiced at least three to five times.
The arrangement of coordinated training prescription is a kind of intensive training, which needs to lay a good foundation in preparation period and exercise period, and there is no special coordinated training in adjustment period and competition period. In the prescription arrangement, we can follow the 20 items listed in the above training methods, plus other items compiled by the coach. The intensity is 70% and the frequency is three times a week. The operation is as follows:
1. vertical jump: feet together, hands bent and jumped up.
2. Jump back and forth: The method is the same as above, but jump back and forth.
3. side jump: the method is the same as above, but jump left and right.
4. Box jump: The method is the same as above, but jump to the box position.
5. Turn and jump: The method is the same as above, but after jumping, turn to 180 degrees and land. In order to keep balance, you can jump left and right.
6. Jump direction: the method is the same as above, but jump on one foot.
7. Crossing step: There are two kinds of crossing: left crossing and right crossing.
8. Reverse movement of hands and feet: standing on one foot with both hands is opposite to lifting the feet.
9. Stand first and then squat: stand first and then squat, then push your feet back with both hands, then put your feet back in place, and finally stand up.
This is a set of cycles. The others are 10. Gyro rolling, 1 1. Left foot bends, right hand touches, 12. Swing with the ball, 13. Throw the ball standing. 14. Sit and throw the ball. 15.
Of course, coordinated training requires speed, time and movements, that is, the more complicated the movements, the better the learning effect, so the coach can make up 10 to 20 movements, accounting for about 30 events.
I often see other people's wonderful layups, and I have tried layups, but I often dribble past people and prepare to hold the ball with both hands. When I don't catch the ball during layups, the ball comes out. Many layups are like this. What's wrong with the pace of action?
From what you said, it should not be a matter of footwork, but a matter of holding the ball when catching it. That is, when you receive the ball and prepare for layup, you may hold the ball with one hand and then prepare for layup; But because you have small hands and hold the ball with one hand, it is easy to drop it. For the above problems, I often give students advice in teaching that if we are ready to make a layup after receiving the ball (until the ball leaves our hands), then the whole process will be divided into ten equal parts. Then start from catching the ball, one tenth is holding the ball with both hands, two tenths, three tenths and so on. They all hold the ball with both hands when any pedal takes off from the ground, even seven out of ten hold the ball with both hands, until eight out of ten hold the ball with one hand, and finally nine out of ten and three out of ten do.
