Two forms of dual-propagation taxis for beginners

About the two types of beginners, the two forms of two-legged gliding are the two-footed support, namely, the left foot support and the right foot squatting; then turn the right foot support and use your left foot to squat. Here also to talk about what is the single-leg support slide, the main point of the single-leg support is to use the support leg depression, the popular description is that which leg (load-bearing leg) stands on the ground, with which leg stretched, this It is required that the landing leg must be curved in order to have initial conditions for stretching.

There are two forms of double support for beginners. One is very obvious. The other is not obvious. It is often mistaken for no problem. Today we will focus on the two different forms of dual support for roller skating beginners and propose preliminary solutions. Method.

1. Left foot support (center of gravity), use your right foot to make a slamming action; then turn right foot support, use your left foot to squat, and clearly double-support for taxiing. Continue to use the same squat approach after your legs. This is a relatively common posture, and will be accompanied by riding a heavy heart.

2, the left foot support, with the right foot to the ground, and then the center of gravity part of the conversion to the right foot, and the conversion is faster, so it does not seem obvious, and its power from the non-supporting legs and a small part of the supporting leg extension This double-support gliding method is often not easily discernible, and it is also accompanied by a relatively heavy riding center, the two feet can not be close together, the basic process of taxiing is fork legs (inverted V).

For the two-legged support gliding, it is not a technical problem for many people at all, but a problem, because in many people's minds, "skating is a kind of two-legged interactive movement. When skating, it is generally a foot. And the other foot is to push the foot," (taken from the paper "A Three-Dimensional Kinematics Analysis of the Excellent Racing Skating Player Performing an Action" by a master student in Sports Department of National Pingtung Teachers College, Taiwan). Due to the prevalence of this misconception and the uneven level of coaching, beginners generally suffer from bipedal support and glide.

For beginners, the danger of feet support is that riding on the center of gravity, the center of gravity is chaotic, the left and right feet are competing, the gliding efficiency is extremely low, and the serious dragging and slicking of water slides can easily cause instability at high speeds, which seriously hinders the application of advanced development after speed skating. .

How to solve the problem of double support sliding? The recommendations are as follows: roller skating should conform to the laws of nature. Like walking and running, the front foot should fall to the ground, and the rear foot should leave the ground. At the same time, the floating leg (swinging the leg) should fall to the ground. leg.

Dual-support gliding is also often caused by the lameness of early-stage training and training in the early stage. Therefore, we must avoid floating the feet, but we must emphasize “falling” to support the legs. It is also necessary to pay attention to strengthening leg strength training and land training in order to provide a guarantee of strength for improving double-support gliding. In addition, the floating leg landing support legs must be curved, which makes the floating legs easier to fall when the ground, and second, only the proper bending of the legs in order to avoid the anti-support when landing, in order to carry out a normal stretching action, like a bow Archery, bow pulled far enough to shoot a truth.

As long as it is not supported by a single support leg, it belongs to double-support sliding. Emphasize the degree of bending of the knee leg of the floating leg. It is strictly forbidden to drop the leg straight to the ground.

Beginners' double-support gliding also has psychological effects, and it is safer to ride on the double-support (anti-support) riding center of gravity and it is not easy to dump on the outside of the body. Therefore, in addition to training, it is also necessary to express the harm of beginners' double support, establish confidence, and actively correct the wrong way of gliding.

Of course, in the speed skating, a lot of technical movement training and actual gliding will use special dual-support gliding methods, and besides, it will be another matter.
