Slide down to children what are the benefits?

 The continuity of playground slidescreating children\'s game experience
Let children\'s limbs and body coordination get continuously fully exercise on a complete set of facilities, is the center of the strange music product concept. It is strange music based on the theory of creating the continuity of "children\'s game experience" for the implementation of the implementation, eventually led to the global children\'s amusement school play equipmentindustry design and the epochal changes of the products.

Children from slide down, gravitational potential energy into kinetic energy, the accord with energy conservation?

Children from playground slidesdown it is not about the law of conservation of energy, children most of the gravitational potential energy into kinetic energy, but also part of the gravitational potential energy into internal energy (friction power is converted to internal energy)

Children from chute is what phenomenon

If the playground equipment slidesparameters do not change, the accelerated motion along the slide down, due to gravity. Violation. Kinetic energy, gravitational potential energy decreases, but there is friction, some mechanical energy into internal energy, namely hip fever, that is friction consumes energy. But if the topic of the premise without friction, that is, regardless of the loss.

The standard size of bunkers

Long jump and triple jump childrens sandpitsat least 2.75 meters wide, the most 3 metres wide. ZhuPaoDao 1.22 meters wide, at least 40 meters long. On the far side of the take off board, cutting edge to the bunker from at least 10 meters. The triple jump jump line to bunker near the distance at least 13 meters (11 meters) is a girl, to the bunker at least 21 meters remote distance. Pit sand in a horizontal plane with the take off board surface. Take off board made from wood, 1.22 meters long, 20 centimeters wide, painted white.

Why bunker long jump record will be so high? How do they dance?

Standing long jump movement, jump out of the performance is different also. So how to under the condition of invariable in physical quality, jump far? After teaching practice and exploration of the standing long jump again and again, some improved technologies and methods, received good results. Its practices are as follows:
A foot or two equal stance
For both feet, is often neglected. Sports teaching is divided on this question: some "two legs slightly points"; Some requirements "two feet and shoulder width apart. As to stand in what position, the teaching material has no specific rules, so most of the physical education teachers "eight" word station method. In the teaching practice, I find it difficult to grasp the scale, the latter is clear, but larger. My way is: two feet first station set up are posture, then tiptoe to support before, two feet with separate to two legs become parallel position in both sides. In this way, toes forward, c onsistent with the direction, at the same time two legs in a vertical position, basic does not produce Angle, and knee and ankle movement. And students can easy to learn.
Second, the motion of the arms with breathing
indoor swingarm and breathing with reasonable is very important. In the teaching, relax from down to up in advance when placing arm slowly on the head, follow easily breathe in, and then exhale on both sides by go up to the rear and two arms. When to jump before the two arms are quickly from down to up on the head, and now with the fast and deep breath with the hem on both sides to the rear, action as fast, but this is not out, but rather tight. This provides the maximum energy for muscle before takeoff, strengthen muscles takeoff of the instantaneous power.
Three, body center of gravity moved forward
In the teaching, my way is: before takeoff, as top-down to on both sides of the re ar two arms swing, leans forward, then the two arms QuCheng crouch position, heel lift, with forefoot grip, control the body balance, center of gravity shift. Although center of gravity forward isn\'t very big, but it is very important. So, you\'ll jump and do not have to power consumption as the center of gravity forward, create conditions for body above leaps forward.
Four, is the key
Jump when push the pendulum effect how, is an important factor to determine the body leaps far degrees. In the teaching, pendulum method of two arms coming up, I\'m not as simple as teaching material after the above put forward. Because that place only applies to two arms, and cannot drive the whole body. I adopt the high jump jump when two arm pendulum method, but the direction is not only upward, but above put forward. Jump, two feet with forefoot ground rapidly, at the same time, two arms made powerful swinging forward above on both sides, the above leaps forward.

Why do I not jump bunkers, standing long jump far

Jumped kids sandpitsand has a high requirement on the sprint speed. And standing long jump, it is depends on the leg explosive in the moment. Think about a lot of short diameter of athletes, can JianXiang jump, it is for this reason. Of approach speed in situ jump is good, but not enough, and there is no professional learning through the sharp jump techniques.

Training jump jumping pit

Jump the kids sandpitscalled jump datong little meaning mainly you leg strength can be summed up as long as your leg strength
Leap, you can do every day every day with running at full speed of 60 m (have you step step about a meter)
Suddenly leaped and do every day to do 5 groups each group of 10 times that by the time the game can full play to the running speed to exercise can strengthen your jump when the inertia of the leg strength enhancement can make you jump higher and have highly plus you run far degrees of inertia is equal to you according to my hair method can scores between 4.80-5.1 good practice can be higher!
Tip: as far as possible when starting strides and sprint with a jumper at the instant head must be high hands lifted up, to make an unexpected results when you get it
