主题1-交替的平衡

We propose you tostart changing the way you think about technique from a first theme:alternating balance. Try to think that, like when you walk, you alternativelylean on one foot and on the other one. This message is for everyone: from theabsolute beginner to the World Cup athlete and it will be useful for the restof your skiing life!

在第一阶段，我们建议你开始改变你对技术的思考方式：交替的平衡。试着想，当你走路的时候，你的平衡交替依赖着一只脚，然后是另一只。这个信息对每个人都适用：从初学者一直到世界杯运动员，并将伴随着我们的整个滑雪生涯。

The first twovideos will explain this.  Look at themand freely discuss them!

第一批两个视频即阐述此观点。请观看它们并自由讨论！

Theme 1 – Balancealternation

主题1-交替的平衡

Video 1 – STARTINGPOINT  (being aware of the alternation)

Video 2 – FROMWALL TO WALL (a different way to look at ourselves as skiers)

视频2-墙到墙（作为滑雪者从另一个角度看待自己）

我们将针对以上主题（主题1-交替的平衡）开展3天的自由讨论，本期自由讨论截止时间：2018年10月6日晚上，之后，Jam Session将对本主题进行总结述评。

[size=18.6667px]自由讨论在我们的微信群里进行，我们将及时把结果在此公布。

Valerio Malfatto对上述[size=18.6667px]主题1-交替的平衡两个视频的解释：
The first videos were designed to understand the importance of full and safe balance on the outdoor ski and the example of walking and running was because when we walk or run or jump from one stone to another we definitely have a full balance given from the collaboration of the foot and shoulder on that foot.
The example of the "wall to wall" ends this discussion and in the skier's mind the action can be simplified with this strong idea together with that of big steps (big turns) or small steps (small turns) here and there . This is the purpose to learn a basic concept: learn to feel the alternation of full balance left and right.

第一批60个视频小结

Dear friends!

朋友们！

JamSession wants to thank you for your participation with your videos!

Jam Session感谢大家参与提交滑雪视频！

We appreciated thegreat passion, the great attention to the technique and your strong will toimprove your skiing.

我们赞赏：你们表现出来的热情，对于技术的关注，以及改善自己滑行技能的追求。

In the first 60videos we were able to evaluate different levels and different ages.

在第一批提交的这60个视频中，基于对不同水平，不同年龄滑雪者的技术评价如下：

·      In the intermediate skiers, we appreciated a strong focus and disciplinein the chest position.

对于中级水平滑雪者，我们认为，需要重点关注和练习胸部的位置

·      In the advanced skiers, we found different ways in the trunk and in thearms usage, as well as different skills in gripping. In some cases, anklesrigidity and a static skiing.

对于更高水平的滑雪者，我们发现不同的身体姿态和手臂使用方式，对应于不同的抓雪技能。在某些案例中，脚踝僵硬而不灵活。

·       In the most expert skiers, we noticed agood level, but with some passivity in the exchange phase and at the beginningof the turn. In some cases, a too emphasized vertical movement and tooemphasized basin movements.

对于专家级的滑雪者，我们看到了很高的水平，但是，在转换阶段的被动型产生于弯儿开始的部分。在某些案例中，垂直方向的动作过于强烈，骨盆的动作过于强烈。

·       In the athletes, a pretty goodtechnique, but limited focus on speed.

对于运动员，非常好的技术，但技术重点要多放在速度上。

Generallyspeaking, the motions and the technical problems are the very same that we cansee the skiers of any levels all over the world.

总体来言，动作和技术问题都是极其相似的，适用于世界上所有水平的滑雪者。

We believe thatall skiers in the world tend to focus too much on chest, on arms and on basin.In the schools around the world it is actually mentioned that feet areimportant, but at the end of the day, only few focus on them. They tend to lookfor feet effectiveness through corrections directed to the upper part of thebody.  Jam Session believes that at everystep it is necessary to always start from the feet, and to connect them to allother possible issues, that are different and specific for each level.

我们认为世界上所有的滑雪者，将关注点过于集中于如胸部，手臂，骨盆。在世界上很多学校，确实强调脚部的重要性，但是在每一天滑雪结束时，只给予脚部一点点关注。他们倾向于在修正上身朝向的练习中，提高脚部的效率。Jam Session相信所有滑雪步骤都必然最先由脚部开始，然后连接并导向所有可能的出口，出口的不同和特殊性对应于不同的滑雪水平。

1)     We want you to focus on feet, ankles, muscular tensions. Balance dependson feet. It is necessary to understand how feet should work, to learn how tofeel them, to think to the feet instead of thinking to the other parts of thebody. Body will balance as a consequence.

1）我们希望你关注于脚，脚踝，肌肉紧张度。平衡依赖于脚。我们很有必要了解脚如何工作，学会感觉它们，先要考虑脚部问题而不是去想身体的其他部位。身体建立的平衡是一个结果。

2)      We want you to focus on the direction ofthe action and on the timing: you need to learn how to choose in advance whereyou want to go, with which intensity and with which progression.

2)我们希望你关注动作的方向和时机：你需要学会预先选择你下一步的滑行目的，以及相对应的动作强弱和采取怎样的步骤。

3)      In the turn there is a strong drop ofaltitude. You need to learn how to look it, how to want it,  how to perceive it and how to manage it.

3）在转弯时，你会受到很强的重力作用力。你需要学会如何看到它，怎样期待它，怎么理解它，以及如何控制它。

4)      We want you to ski well, with a confidentskiing and a natural, not artificial beauty. You should not look for stylewithout substance.

4）我们希望你滑的更好，使用滑雪技能更自信，更自然，而不造作。在没有掌握本质内容之前，不需要考虑形式风格上的问题。

The “request” andthe “instructions” for the balance come from the feet.  From them, the muscles that create thebalance are called. A baby learns how to walk using the foot. No one wouldteach a baby how to walk starting from teaching him how to use arms and chest.

有关平衡的“反馈”和“指示”来自于脚部。从脚部开始，肌肉平衡被唤醒。婴儿学步从脚部开始。没有人会教孩子学步让他先从使用手臂和胸部开始。

Let’s not think aboutstyle, about  form. Parents would not askthe soccer or ping pong trainer to teach style. Let’s focus on theeffectiveness of the gesture, and our style will come out spontaneously. And itwill be the best possible for us.

让我们不要考虑形式风格问题。父母送孩子学运动，不会问足球或乒乓球教练有关形式风格的问题。让我们关注于动作的效果，我们的滑行风格会自然而然地产生，这也是最好的结果。

Let’s aim atspeed. It is not, and it should not be, the final target, unless of theathletes. But speed is the best teacher for any skier: the most skilled one,the most severe and the most sincere!

让我们关注速度。和运动员不一样，对于我们，速度不是，而且也不应该是最终的目标。但是，对所有滑雪者来说，速度是最好的老师：更专业，更严格，更真实！

It would be useful to read thoughts about sensations, the quality perceived in the lateral equilibrium, the importance of alternating the balance with the right timing, intensity and awareness.

If we want to talk about how to ski better, it would be useful to know if the friends skiers consider those images useful to be more aware of the technical gesture. If so, why? If not, why? It is not important to discuss the style of this or that demonstrator, Italian, American, New Zealand, Canadian or other.

Theme 2 concerns the difference between steering and carving and suggests an image to make lateral tilting of the feet and ankles easier.

It is important to try at home, on the floor, to fix in the mind and body the sensations (especially feet and ankles) and the different sensations between steering and cutting.

It is important to understand the differences in movement and muscle tension.

We can analyze the best and most beautiful skiers in the world but if we do not collect the sensations from ourselves we will not go very far!

视频分析自由讨论第二课：
视频1：走刃还是搓雪

视频2：借用一根铅笔演示立刃角度

https://v.qq.com/x/page/w0738zzk5y6.html





解释：
In the two videos of today we enter the theme of how to use the feet and the need to start from the inclination of the feet and ankles to convey the forces on the corners. Important to understand and feel how the muscles work from the feet to the buttocks to give ankle and lateral stability to the ankles and to the corner grip
Testing with the idea of the pencils in front, in the center or behind, makes us feel different muscular interventions that will greatly influence the control of the rotations and the cut.

对于中级水平滑雪者中，关注和练习胸部的位置怎么理解？

对于中级水平滑雪者中，关注和练习胸部的位置怎么理解？

我觉得是指重心落后和胸部朝向的问题

oldzhang

·      In the intermediate skiers, we appreciated a strong focus and disciplinein the chest position.

对于中级水平滑雪者，我们认为，需要重点关注和练习胸部的位置
-----个人理解：姿态和上身朝向问题
·      In the advanced skiers, we found different ways in the trunk and in thearms usage, as well as different skills in gripping. In some cases, anklesrigidity and a static skiing.

对于更高水平的滑雪者，我们发现不同的身体姿态和手臂使用方式，对应于不同的抓雪技能。在某些案例中，脚踝僵硬而不灵活。
个人理解：问题在于蹬出去收不回来，立刃不足，控制力不强
·       In the most expert skiers, we noticed agood level, but with some passivity in the exchange phase and at the beginningof the turn. In some cases, a too emphasized vertical movement and tooemphasized basin movements.

对于专家级的滑雪者，我们看到了很高的水平，但是，在转换阶段的被动型产生于弯儿开始的部分。在某些案例中，垂直方向的动作过于强烈，骨盆的动作过于强烈。
个人理解：转换时机过晚造成不必要的拖延，轴转的问题，过于明显的引身
