For two years, I have worked as a ``ski instructor who does not go out
and ski with customers'' and ``a ski school that only provides lectures
inside the building.'' A challenging endeavor for me. From there, I was
able to get a solid response. First of all, we would like to express our
deepest gratitude to all the guests who participated in this experiment.
Now, regarding the B-tele training course (called B-tele), until last season,
it was mainly held on weekends for one night and two days. The content
of the lecture is roughly divided into three parts. Please take a look
at what I roughly wrote on A4 copy paper and pasted it below. Each part
takes about 1.5 to 2 hours. The order is 1, 2, and 3. Now, as an attempt
from this season, we will make it so that each part can be taken individually.
In other words, I had him come one day and do part 1 in 2 hours. Next time
you come, I'll have 2. Next, 3. This completes the B-tele lecture. All
that's left to do is integrate and put it into practice on your own. Of
course, the conventional ``1 night and 2 days B-tele 3 part completion
course'' can also be arranged once a month. The night session is also important
(lol). Of course, it is also possible to take all three parts in one day.
The tuition fee is 10,000 yen/1 part/1.5-2 hours as a private lesson. There
are three start times per day. Please see the table below and let me know
which time is convenient for you. Reservation status is on a separate page
(Reservation Status). On the other hand, if you choose one night and two days, it will be a group lesson, so it will be much cheaper at 36,000 yen including accommodation and two meals. I would like to mention that you will have plenty of time to ski after being freed from lectures, so don't worry. We also offer cheap lift tickets to those taking lessons or staying overnight, so please take advantage of this. The 1 night 2 day course starts in the afternoon. You can get lift tickets, so you can ski to your heart's content from morning until noon. If you're eating at home, don't forget to make a lunch reservation. Inquiry/Application

Around B-tele
A is that skiing is all about turns. B: When skiing, the first step is
to operate the brakes. A is that the brake is involved in the turn. B is
a combination of independent braking and direction changes. A is to wait
for the brakes to work before entering the next turn. B allows you to operate
the brakes regardless of the turn, so you don't have to wait. Therefore,
A tends to have a larger turn arc. B can be either small or large. A is
that the steep slope is difficult. B: Braking is easier on steep slopes
than on gentle slopes. A is to put your weight on the board. Pushing and
pulling the board is B. So far, both alpine skiing and telemarking are
common. In telemark, A-tele and B-tele. A-tele worships telemark stance.
Or cosplay. . B-tele focuses on the advantage of tools. In other words,
it must be heel-free or low-cuff boots. While the A-tele's highlight is
the unique telemark stance in the latter half of the turn, the B's highlight
is the split second of the transition and subsequent modest braking maneuvers.
A-tele's bold movements are cool. On the other hand, the quiet movement
of B-tele is also cool. However, if I'm skiing in a mountain with complicated
conditions, I'll descend in B-tele mode.
Let's start with the center of mass. Center of mass here means the center
of the skeleton. When I tried shaking it, it was the part that didn't shake
the most. I assume that it is probably under the lungs or in the solar
plexus. Joints at the same distance from this point move in the same way
in pairs. Well, imagine that. For example, the shoulder bones and pelvis.
For example, elbows and knees. For example, wrists and ankles. It is easy
to bend your elbows and knees at the same time, but the movement of bending
your elbows while extending your knees can be momentarily confusing. Also,
the bone block near the center of mass is large, and as you move away from
it, it becomes thinner, smaller, and finer. The same goes for the amount
of muscles, muscles, and tendons involved. There are a small number of
large bones and large muscles in the center of the body. There are many
small bones and many tendons at the ends of the body. I draw this diagram
on the whiteboard and then I say: Make sure your power comes from the center
of your body. However, there is a problem: the large mass of bones and
muscles in the center is stupid. Powerful but stupid. On the other hand,
the feet and hands are made up of numerous joints and small bones, and
although they may not be able to exert great force, they are dexterous
and smart. This is the relationship between the center and the edges of
the body. therefore! The role of the hands and feet is to explore and perceive
the situation, and the role of the bones and muscles in the center of the
body is to generate force. Can you imagine it somehow? Let's take it one
step further from here. I think there are all sorts of things to consider
when trying to improve your skiing, but focusing on the direction of your
hips or shoulders, for example, is not an effective method. The reason
is that my hips and shoulders are stupid. It's a part that's hard to recognize
on your own. Therefore, even if the instructor points it out, it cannot
be corrected immediately. It's impossible in the first place. If anything,
I think the problem lies in the lack of education of the instructor who
points out that part. On the other hand, what about hands and feet? ``Raise
your index finger~'' Everyone will immediately do the same. This is what
it means to be smart. Well, it's time for the conclusion. Downhill skiing
requires a lot of strength. That power comes from the center of your body.
It would be more continuous if the output could be generated from skeletal
movements rather than muscles. An easy mistake to make is to focus on the
center of the body and try to move it directly and consciously. This is
a difficult task. The correct answer is to hold the output switch and scale
on your hands and feet. Focus on smart hands and feet, use them as commands,
and control output from the center. This is my B-tele. Specifically, we
focus on how to move around the feet, which is expressed as "CHU♪"
in Japanese. Unfortunately, this can only be expressed face-to-face. .
center of mass から始めましょうか。ここで言うcenter of massとは骨格（骨組み）の中心であることを意味します。揺らしてみて一番揺れないところ。おそらくは肺の下、みぞおちの当たりであろうと想定します。ここから同距離の関節は対の関係で同じような動きをします。まぁそうだと想像してみてください。例えば肩の骨と骨盤。例えば肘と膝。例えば手首と足首。肘と膝を同時に曲げるのは簡単ですが、肘を曲げる一方で膝を伸ばす動きは一瞬戸惑いを生じます。また、center
of massに近い骨のブロックは大きくて、そこから離れるに従い細く、小さく、そして細かくなっていきます。まつわる筋肉や筋、腱の量も同様です。身体の中心部には数の少ない大きな骨と大きな筋肉が。身体の端には多数の細かな骨と多数の腱が。ホワイトボードにこの図を描き、次に僕はこう言います。パワーの出どころは身体の中心部分からにしましょう。しかし問題があって、中心部分の大塊の骨や筋肉は馬鹿なんです。力はあるけど馬鹿。一方で、数多くの関節や細かな骨の集合体である足や手は、大きな力は出せないけれでも、器用でスマートなんですと。これが身体の中心部と端っこの関係性です。ゆえに！状況を探り、知覚してするのは手や足の役目とし、力を出すのは身体の中心の骨や筋肉の役目とします。なんとなくでもイメージできますかね？ここからはもう一段踏み込みます。スキーを上達しようとするときに、あらゆる着眼点があるとは思うのですが、例えば腰の向きであるとか肩であるとかに着眼するのは有効な方法とは言えません。理由は腰も肩も馬鹿だからです。自身で認識しずらい部位なんですね。ゆえにインストラクターに指摘されたとしても即座には修正ができません。そもそも無理なんです。どちらかというとその部位を指摘するインストラクターの側に問題があると僕は思っています。さて一方で、手や足に関してはどうでしょう。「人差し指あげて〜」全員即座に同じ動作となるでしょう。これがスマートであるということです。さてそろそろ結論です。ダウンヒルスキーには大きな力が必要です。その力は身体の中心部分からひねり出します。筋肉、というよりは骨格の動きから出力できればより継続的でしょう。そこで陥りやすいミスが、身体の中心部分に着眼し、直接的に且つ意識的に動かそうとすることです。これは難しい作業です。正解は、出力のスイッチや目盛りを手や足に持つです。スマートな手や足に着眼し、指揮とし、中心よりの出力をコントロールする。これが僕のB-teleです。具体的には足周りの動かし方に着眼するのですが、日本語で「CHU♪」と表しています。残念ながらこれに関しては対面でしか表現できないのです。。
Telemark skiers seem to be bad at talking about technique. why? I have a hypothesis. The hypothesis is that there is no goals to aim for. So, what is the goal of someone who has started telemark skiing? So, without calling it a goal, what would you say is your immediate goal? Perhaps it is the completion of a stable telemark turn based on the telemark position. You opened those legs back and forth. And, unexpectedly, that immediate goal turned out to be a dead-end goal...and even now, more than ten years later, you havn't grown much since then. . How do you react when someone says this? “Have you not only been acting a telemark position?” And in fact, perhaps you are dimly aware of it? The goal of skiing and the goal of acting are not the same. If the way they skied with their legs spread apart was on the same line as the goal of skiing, they would be able to openly discuss techniques well. What about reality? Perhaps,50% of people put effort into acting. Half of the remaining people who have completed that stage are struggling to approach the strength of alpine skiing, and half are starting to perform again with weaker equipment. This is my analysis. Including in YouTube. Now then, what exactly is the goal of skiing? It can be explained like this. ``It's what comes after leveraging the advantages of equipment.'' There is a goal reached by alpine skiers with well-secured, high-cut alpine boots. On the other hand, there is the goal of telemark skiing with a heel-free system. There will also be a light XCD. I've been thinking about what it would be like to express the surroundings close to that goal in one catchy word. Please listen first. When it comes to alpine skiing, it's "strength" and "violence." When it comes to telemarking, it's ``dexterity'' and ``softness.'' If this were to become a reality, don't you think it would be a wonderful place to live? And how foolish it is to try to make telemark skiing closer to alpine skiing. One more thing. Regarding telemarking, it is possible to open the legs forward and backward as a characteristic of the equipment, and it is considered to be an icon and a must, but unfortunately it is not an advantage in downhill. One of the advantages appears when both feet are together. Please take a look at the "B-tele" icon I'm talking about. For example, if we set "dexterity" and "softness" as goals, how do we proceed from there? Why not think about it?
テレマークスキーヤーはテクニックについて語ることが苦手なようです。なぜか？僕には一つの仮説があります。それは、目指すべきスキーのゴールが無いから、という仮説。さて、テレマークスキーを始めた人の目標とするゴールとは何でしょう？ではゴールとまでは言わず、当面の達成目標と言ったら何でしょう？おそらくそれは、テレマークポジションによる安定したテレマークターンの完成ではないでしょうか。あの足を前後に開いたね。そして、その当面のゴールが案外と行き止まりのゴールであったりして・・そして十年以上経った今でもそこからさほど成長はしていない。。そんなあなたはこう言われるとどう反応しますかね？「あなたはテレマークポジションを演じてきただけではないですか？」そして実のところ、うっすらと気付いているのではないでしょうか？スキーのゴールと演じることのゴールが一緒ではない、、ということを。もし、足を前後に開いたあの滑り方がスキーのゴールと同じライン上にあるのならば、彼らは堂々と技術論を交わすことができるでしょう。現実はどうでしょう。演じることに努力している人が50%。残りのその段階を終えた人の半分がアルペンスキーの力強さに近づけようと奮闘し、半分の人が弱めな道具でまた演じ始めている。僕の見方です。YouTubeを含めてね。 さて、ではそんなスキーのゴールとはいったい何でしょう？それはおそらくこう説明することができるかもしれません。「道具の持つ利点を発揮させた先にあるもの」、と。しっかりと固定され、ハイカットなアルペンブーツのアルペンスキーが到達するゴールがあります。また一方ではヒールフリーなシステムのテレマークスキーの到達するゴールがあります。軽快なXCDにもあるでしょう。そのゴールに近い周囲を、キャッチーなone
word で表現できたらば・・と僕は考えてまいりました。まずは聞いてください。アルペンスキーに関しては「強さ」「暴力性」です。テレマークに関しては「器用さ」「柔らかさ」です。もしこれを現実としたならば、それはなんてステキな住み分けなんだろう、とは思いませんか？そしてテレマークスキーをアルペンスキーに近づけようとすることがいかに愚挙であるか、ということも。さらにもう一つ。テレマークに関しては、足を前後に開くことは、道具の特性として可能であり、さもアイコンでありマストのように思われておりますが、残念ながらダウンヒルにおいては利点にはなりえません。なりません。。利点のひとつ。これは両足が揃ったときに現れます。僕が言う「B-tele」のアイコンをご覧ください。例えばで「器用さ」と「柔らかさ」をゴールに設定し、ここからどう展開していくのだろうか？考えてみてはいかがでしょう。
There are two elements to braking is skidding and burying. Use skidding on hard slopes, and burying ski in thick snow conditions. The key point here is that both skidding and burying tech primarily use the mountain side ski. By streching the body joints, you can push and bend the ski. An interesting point here is that only the back half of the ski is bended. This means that it is not bended eitire ski. The technical part here requires a little more explanation, but I'll omit it here. Now, after blaking, shorten the body joints and return the ski. It will instantly we are in air and the speed up. If there is a twist in advance, it will rotate instantly. In other words, if you strech your leg and push the mountain side ski to the twisting direction, the ski will automatically rotate quickly when you return it. It's in the air, and fast.
ブレーキングの要素は二つです。ズラシ（skidding）と埋める（bury）です。硬い斜面ではズラシを、雪に厚みのあるコンディションでは埋めるを使います。そこてポイントとなるのが、ズラシも埋めるも山側のスキーをメインに使うという部分です。関節を伸ばすことによってスキーをたわませ、押し込みます。着眼は、たわませるのはスキーの後ろ半分だけというところです。スキーのトップからテールまでをたわませるわけではない、と言うことです。ここのテクニック部分に関してはもう少し説明が要るのですが、ここでは省きます。さてブレーキの後は間接を縮めて戻します。間接を縮めて戻すと瞬間に空中（in
the air）になりスピードアップします。事前にひねりがあればそこで瞬間で回ります。つまりは、捻る方向で山側のスキーを押し伸ばしていれば、戻した時には自動的に板が回るという寸法です。それは空中で、しかも素早く。そしたらばまた違うサイドのアウトエッジの後半部分に徐々に力を加え、を繰り返しているのが僕の滑りです。
Turns are often talked about when it comes to downhill skiing techniques. In other words, it's about the turn arc. It's true that turning itself is fun and thrilling, as I am too. However, when looking at technique as a ski instructor, the most important thing is control your speed not brush up the arc of turn. And, at the risk of sounding rude, there is no relationship between turn arc and speed control. That is my position. You'll be surprised, right? So I'll explain. The key to speed control is brake operation. This means that the brakes work properly, or that you can control the strength or weakness at will. If you do this, the speed will naturally increase. I think speed control means braking (deceleration) control on slopes where the physics of falling occur . It will accelerate if you do nothing. . When it comes to braking, there are two patterns: one is waiting for the speed to drop, and another is able to reduce the speed at will. The former are people who think ski is turn. After his speed has dropped nicely, he starts his next turn. In other words, the waiting type. They can ski up to intermediate slopes, but are not good at steep slopes. In the first place, on a slope of over 40 degrees, would you choose to turn? Maybe we use skidding way and slide down. Yes, the speed control technique that can be used on steep slopes can be said to be a general-purpose braking technique. Here, we are talking about skidding. This is effective in hard snow conditions. On the other hand, some conditions is powdery or crusty, and thick. In this case, once the ski is sinked, it will become difficult to move. So what can we do to slow down? All you have to do is bury your skis. When your ski sinks, you lose speed. Many people may have had the experience of → sudden speed reduction → falling. There are two reasons. One is because it will bury the entire ski. To be more specific, the entire ski sinks, and the resistance in the front half of the ski is applied as a brake. That's why I get caught. It's best to bury not the entire board, but the back half from the boots. And the second reason is because of riding by own waight. In other words, it's because your own weight is ski buried. Weight remains constant. If you convert waight from to pressure, the adjustment of burying will be at will. The words for exercise are "push" and "pull." You can adjust the amount of burying by touching it. And that leads to controlling speed. In other words, bury ski and slow down. Float and speed up. Bury the tail of the ski to slow down, float it to speed up. Actually, the skidding mentioned earlier is also the same. Slide the tail to apply brake, return to release. It may come as a surprise, but the foot that plays this role is the ``mountain side ski' when you stand sideways on a slope.And using is the back half of outside edge. This is important. In the first place, it is not the downhill side ski that controls the brakes. Well, let's summarize. The important thing is not the turn arc but the brake control. The skis on the mountain side play the main role of braking. Using back half of the outside edge of the mountain side ski. On hard slopes, skidding here will control the brakes. In thick snow, this part is buried to provide resistance and act as a brake. A brake is something you operate. Manipulate strength and weakness. Apply the brakes instead of waiting for them to apply. For this purpose, it is effective to convert from a weight on movement to a push&pull movement. And this is where the advantage of being heel-free systems comes into play.
Compared to alpine skis, heel-free skis can make turns with a smaller turning radius. This is because the axis of rotation can be made straighter. This is because when you do a contraction motion, your heels are raised, allowing your knees to be positioned in front of you, which allows you to keep your feet directly under your upper body. The line connecting this upper body and both legs is the axis of rotation. A straight axis of rotation describes the smallest arc. The image looks like it's spinning on the spot. By the way, the movement of shrinking and becoming smaller is different from the movement of crouching down. The moment it shrinks, the ski is in the air. It spins best in the air. From the outside it may look like a momentary movement. Changing this to a medium or long turn is really easy as all you have to do is slow down this movement. By the way, the body must be stretched before the action of shortening the body. As I mentioned earlier, I apply the brakes by stretching my body. By stretching the joint of your foot on the mountain side, power is transmitted from your ankle to the ski, causing the tail of the ski to skid, which acts as a brake. In deep snow, the tail becomes buried and also acts as a brake. Extend your body when braking, and contract your body when rotating.

TOP?
I am simply distinguishing between telemarks as ``A-tele'' and ``B-tele,''
and this is not the general way of thinking in Japan. First, this is an
important point. B-tele is my original idea, and it took me about 25 years
as a ski instructor specializing in telemark skiing to come up with this
idea. I have attached some materials with ideas, so I hope they help you
understand. I would like to say a little about A-tele here. What is A-tele?
All ideas other than B-tele are A-tele. In other words, all general telemarks
are all A-tele. Of course, this includes technical theory and teaching
methods. And I didn't create B by denying A. My exact position is that
there is A and B. Because A exists completely. In other words, it has existed
for a long time. After gaining the judgment of time, what we have now is
A. And there is a reason why it continues to exist. There's a reason why
you lower your hips and spread your legs forward and back. Is it really
a physical reason, or is it something more internal than that? For example,
something is simply fun! Excited! Or maybe it's difficult and I like it.
It feels like I'm doing it compared to alpine skiing, etc. In any case,
A exists. In the past, I also swam in this A, and worked as a ski instructor
because I thought it would be better to do something like this or something
like that in A. Generally speaking, how can that unique style and telemark
position be stabilized in turns? Or perhaps he was devising the meaning
of opening his legs forward and backward from various possibilities. In
any case, the main premise is that there is a turn arc. How can we apply
telemark position to the process of shaping the turn arc? Well, at the
time, I thought it was the role of a telemark ski instructor to think about
that and communicate that. Fortunately, I am able to look back like this
because I was able to jump out to B, but if I hadn't been able to do so,
I would have continued swimming in A without even realizing that I was
there. Now, this is getting long, but I would like to talk about how I
was able to build B outside of A. The motivation was this question."You
don't want to make turn arcs on such a steep slope right below the mountain
ridgeline. It's super dangerous."On a icy steep slope, you'll start
off by using skidding. Yes,Is it necessary to teach techniques that cannot
be used on steep slopes? I think the techniques that can be used should
be the basis. Moreover, if you open your legs back and forth in a scene
like this, it's over. Is it okay to raise the heel of the foot on the mountain
side? Well, first of all, what is a turn? And do you need a telemark position?
The steep slope made me question the turn itself. Resort slopes do not
have such steep slopes. This realization came from skiing in the mountains.
Now, what is necessary for downhill skiing is brake operation. People who
are good at braking are good at controlling speed. B-tele method was built
with a focus on brake operation alone. A is the turn arc. B is the brake.
B is suitable for all conditions and environments. And in B, telemark skiing
is superior to alpine skiing in a number of ways!! I think this is a gift
that I realized thanks to making B. A indicates its value in terms of slope
and environment where you can enjoy turning arcs. For example, resort ski
slopes. Comfortable slopes and safe environment. Let's actively enjoy turns
or turn arcs. So is speed. It may be an exaggeration, but it's a little
violent. On the other hand, the world of B-tele is quieter, softer, and
has a lighter touchness. A and B. It’s good to have both! I wrote it for
a long again...
About lead change. B-tele does not have that word or its equivalent movement.
Do you feel uncomfortable when I say that? Actually, there isn't one. But
if you watch the YouTube video, you can clearly see that the front and
back are swapped after each turn. That's called lead change! I understand
what you are saying. But as expected, there are no intentional movements
or words. This is because skiing is not considered based on the arc of
the turn. As mentioned several times, B-tele's method is built around brake
operation. What exactly is the brake operation? This means "skid"
for hard slopes and "bury" for thick snow. And for the part that
you see as a turn, and even the lead change part, in my opinion, the appropriate
word is "Spin." Quick change of direction. Both feet at the same
time. It's in the air. After that, use the skis on the mountain side to
brake and adjust your speed with a mixture of "skid" and "bury."
At this time, the ankle part of the foot on the mountain side is pushed
down in a diagonal direction, so if you wear high-cut boots that make it
difficult for your ankle to move, your heel will look raised, whereas if
you use low-cut boots that have a loose ankle, your heel won't rise as
much. It looks similar to the way you push with your ankles. The appearance
of whether the heel is raised or not just depends on the boots you are
wearing in B-tele. It is by no means intended for a close or wide stance.
So far, this is all about skiing on the mountain side, which is responsible
for applying the brakes. So what about the ski slopes on the valley side?
This is just being pushed forward. As a result of being pushed out, it
is positioned in front. What comes to the position before being pushed
out and becomes the position to be pushed out? Skiing on the mountain side
after a spin. If you push the ski on the mountain side by stretching your
legs (your whole body), your foot on the valley side will move forward.
In fact, this recognition of "forward" is important, as it indicates
what's ahead of you. Naturally, since you are stretching the mountain side
(inner) leg, the valley side (outer) leg will also be stretched. You can
stretch your legs and position your feet in front of your body. This means
that your ankles will stretch. In other words, boots that allow your ankle
to stretch make it easier. In other words, low-cut boots make it easier
to position your feet forward. And while stretching your legs. While moving.
While applying the necessary and sufficient pressure. It's like a willow
leaf knife cutting sashimi... That's off topic. . Skiing on the mountain
side where you apply the brakes below the ankle towards the valley side.
On the other hand, skiing on the valley side simply cuts in the direction
of travel. This is the breakdown of the difference in my ski fore and aft.
Whether or not you call the next movement ``lead cahnge'' or not, in my
intuitive sense it is ``returning to zero.'' It's in the air, so accelerate
straight towards the fall line. Then, we will extend the contracted amount
again, apply the brakes, return to zero, and repeat this process to lower
the altitude. "I'm just going straight downhill, spinning and braking
repeatedly." This is it. Thinking is not turn arc based. This is the
reason why I divided it into B instead of A.
Lead changeについて。B-teleにはその言葉、またはそのチェンジしているに相当する運動が存在しません。と述べたら違和感ありますかね？実際に無いんですよね。でもYouTube動画を見るとワンターンごとに明確に前後が入れ替わっているじゃないか？それをlead chengeと言うのだよ！おっしゃることは分かります。だけどやっぱり無いんですよね、意図した動きも言葉もね。どうしてかというと、ターン弧を前提にスキーを考えないからです。何度か述べているように、B-teleではブレーキ操作をメインにメソッドを構築しています。そのブレーキ操作が具体的になにか？というと硬い斜面では「ズラシ」、厚みのある雪では「埋める」という操作です。そして皆さんがターンに見えている部分、のなかのさらにはlead change部分は、僕の捉えでは「スピン」が適当な言葉となります。素早い方向転換。両足同時に。それは空中で。そのあとは山側のスキーを使って「ズラシ」と「埋める」のミックスでブレーキをかけ速度調整を計ります。この時に、山側の足のくるぶし部分を斜め方向に押し下げるわけですので、足首の動きにくいハイカットブーツではカカトが上がって見えるでしょうし、反対に足首のゆるゆるなローカットブーツだと踵があまり上がらない、くるぶしで押している姿そのままに近い見た目となるわけです。踵が上がっている、上がっていないの見た目は履いているブーツによるわけですよ。決してクローズスタンスとかワイドスタンスを心がけてのものではないのです。さて、ここまではブレーキをかける役目の山側のskiのハナシでした。では谷側のskiはどうなってるの？これは前に押し出されているに過ぎません。押し出された結果、前に位置します。押し出される前の位置に何が来て押し出されるはめになっているのか？それはスピンした後の山側のスキーです。足を（体全体を）伸ばすことで山側のスキーを押しずらすと、谷側の足は前に逃げます。実はこの「前方」という認識が重要で、それは自身の前方を示します。当然、山側の（内側）脚を伸ばしているわけですから谷側（外側）の脚も伸びますよね。脚を伸ばして身体の前方に足が位置できる。これは足首が伸びるということです。言い換えれば、足首の伸びることが可能なブーツだとそれがしやすい。つまりはローカットブーツだと足を前に位置しやすい、そうなります。しかも脚を伸ばしながら。動かしながら。必要十分な圧をかけながら。まるでお刺身を切る柳葉包丁のように・・。話が逸れましたかね？？くるぶし下で谷側に向けてブレーキをかける山側のski。対してシンプルに進行方向に向かって勝手に切っていく谷側のski。これが僕のskiの前後差の内訳です。そして次に続く運動を「lead cahnge」と言うか言わないかは別として、僕の感覚的な言葉でそこは「ゼロに戻す」です。そこは空中なので真っすぐfall lineに向かって加速します。そしたら縮んだ量をまた伸ばしてブレーキをかけていく・・またゼロに戻す、の繰り返しで標高を下げてまいります。「僕はただ直滑降の中でspinとブレーキを繰り返しているだけ」。コレですね。思考がターン弧ベースではない。AでなくてBに分けた理由です。
I'll call them A and B for clarity. A-tele is that the force that bends
the board is mainly your own weight. B-tele is mainly a force that stretches
and pushes the joints. There is a theory that A-tele distributes your weight
evenly on both skis. No, 70% on the front board. No, no, 80% is on the
back board, so in any case, A is mainly concerned with your own weight.
And the image at the base is probably a turn arc. On the other hand, regarding
B, the focus is only on the board on the mountain side, and the source
of the force is the force to push, how much to push and how much to skid.
Or how much to bury. And only the tail of the board. And without leaning
backwards. The purpose is for brakes. This is better with low cuff boots
than with high cuff boots. In other words, the more range of motion you
have in your ankles, the more effective idea B will be.
The another one, B-tele
