1 The Truth about Hip Joint Theory The First Step towards Achieving an Optimum Level of Performance Dr. Toshio Yamauchi was born on January 31 st, 1956 in Ehime Prefecture. He studied Judo Therapy at the Meiji School of Oriental Medicine and underwent training at his older brother s medical treatment facility. Dr. Yamauchi established his own independent institution at the age of 28 and relocated it to Ono City in Fukui Prefecture at the age of 37. Currently, this comprehensive medical treatment facility works with a branch facility in Shiga Prefecture to heal, develop, and support athletes. Dr. Yamauchi also visits various schools and sports facilities to give lectures to young athletes. Recently, technique coaches have demanded their players to efficiently utilize their hips in both their throwing and batting forms. Many trainers and coaches have collected research data on this subject, and we interviewed Dr. Toshio Yamauchi to see what he had to say. The importance of the hip joint has been emphasized in a variety of sports and fields of exercise because so many movements in the human body originate from the hips. I (Dr. Yamauchi) have had over 20 years of experience treating hip joints, and I strongly believe improving the hip s condition improves both everyday health and athletic performance. However, throughout my time researching hip movement I have come to discover that many people are still neglecting the most important thing about improving their hip joints, and that is its misalignment. Correcting this misalignment is the main focus of my work and the Hip Joint Theory that I teach. Developing a Flexible Body So, why does misalignment in the hip joint occur? After examining and

2 inspecting a wide variety of athletes, I have discovered that over 90% of them have some misalignment or problem with their hip joints. One of the main reasons hip joint misalignment occurs is genetics. The hips of children are often very similar to the hips of their parents. Another reason is a change in habits or lifestyle. A decrease in the amount of weight your hips support can also lead to misalignment. For example, in Japan many people have changed their preference in toilets from the traditional Japanese squatting-style toilet to the Western sitting-style toilet. This change has made it no longer necessary for these Western-toilet users to drop their hips into a deep squatting position while using the bathroom. Another prevalent example is the rising number of children who have begun spending less time playing outdoors and more time lounging around indoors watching television or playing video games. The range of mobility of a child s hip joint is exceedingly diminished when a child leads a sedentary lifestyle. Furthermore, oftentimes there isn t a proper stretching coach to guide these children when they enter elementary school and are suddenly required to increase their amount of exercise. Thoroughly stretching the body both statically and dynamically during this period can help them prevent hip joint misalignment later on; however, the reality of the situation is that proper stretching is usually neglected. As a result, many cases of sports-related injuries such as hernias occur after middle school. Retroversion in the pelvis bone (inclined upwards) shifts the hip joint out of place and makes an athlete inflexible. This is the primary cause of many of these sports-related injuries. My hip joint treatment improves and realigns the angle of the pelvis and also corrects overall posture. A more flexible body leads to greater efficiency of movement and supports injury prevention. A truly flexible body. I believe that one can only achieve this with what I call a perfect hip joint, and I base this off of many years of treatment experience. This is also the basis of my hip joint theory. Japanese sumo wrestlers perform a stretch called the matawari where they spread their legs apart almost 180. These big-bodied wrestlers are only able to put their bodies into this position because their hip joints are properly aligned. To put it simply, this level of flexibility is a superb example of the perfect hip joint. However, it must be noted that athletes cannot realign their hip joints on their own. Performing individual stretches every day will increase the mobility of the hip

3 joint to some extent, but they will not completely resolve the more deeply-rooted issues. My treatment provides patients the necessary guidance to realign the hip joint and make it bilaterally symmetrical. Furthermore, athletes undertake hip joint activation training along with the basic treatment which helps to improve the nervous system, strengthen the muscles surrounding the pelvis, and remove any kinks in the nearby ligaments. When I explain the importance of the hip joint to athletes, I mainly emphasize the benefits of realigning the hips and putting them back into the best condition possible. Also, barring any limitations or distortions of the bones, anyone regardless of age or gender can achieve the flexibility required to perform the matawari squat. No one should make excuses about why they are inflexible. Injury Prevention Developing a Strong Body I currently pay visits to various schools and athletic facilities to give lectures on my work. During one of those visits, I was asked by someone in the audience, Why it necessary for me to perfect my hips even though I m not a Sumo wrestler or gymnast? I believe that having a perfectly aligned hip is a key factor in becoming a first-rate player in any sport. For any athlete to perform at their maximum ability level, they must be able to move their body efficiently. In order to do that, they must sufficiently max out their hip joint ability. For example, if you think about the human body in terms of a car, the hip joint would represent its undercarriage. If the tires or axles are misaligned the car will not run straight and it will not be able to reach its maximum speed. A human being on two legs with a misaligned hip joint experiences the same problem. Through the years of experience treating my patients, I have also come to understand that hip joint alignment has a significant effect on other parts of the body; misalignment can cause various problems and pains. For example, oftentimes baseball pitches come to me concerned about pain in their shoulder; however, a good number of these cases are related to hip joint misalignment. The pictures provided in this article are of a baseball player with a misaligned hip joint. You can clearly see that his legs are considerably different lengths,

4 and this disparity almost always results in a distortion of the shoulder joints. When this player brought his elbows together in front of him, their heights were also noticeably uneven. Sleeping facing sideways is one of the major causes of an inflexible hip joint, and spending hours upon hours in that position is a big concern for a person s shoulder joint. If a person continues to do this over many years, the stressed joints will almost certainly shift out of their natural position. Aches and pains in the shoulder, lower back, knee, etc occur when an athlete trains with a heavy workload under these distorted conditions. When athletes begin to fully understand the importance of flexibility, they usually incorporate stretching regimens into their practice time. However, these athletes tend to only stretch while they warm up or cool down and limit their stretching to their own physical capacity because they are afraid of overstretching their muscles. Are these athletes really stretching enough to increase flexibility and prevent injury? The original stretches I have designed have shown positive results in perfecting the hip joint. My treatment experience has shown me that once an athlete gets to the phase where they are able to do the matawari stretch, problems with the nervous system and muscular strength begin to improve. Furthermore, many athletes have experienced a boost in their metabolism, better overall balance, and increased endurance while taking on a rigorous training regimen. Coaches and trainers must also share some of the responsibility when it comes to preventing injuries. There is a good chance that an athlete will develop problems with their hip and injure themselves or begin to feel pain. An inflexible athlete has an especially high risk of having problems with their hip joint, so coaches must identify these issues and begin treatment as early as possible. Hip Joint Treatment and Activation Training I will now explain my hip joint treatment program in more detail. I will refer to the pictures of one of my former patients to help me. This patient was a pitcher from Kumamoto Prefecture s Shuugakukan Senior High School at the time I treated him. Patients who come to my clinic for the full hip joint treatment undergo a 10 day intensive treatment camp. If you look at the pictures taken from before the treatment and compare them to the pictures taken after the treatment, you can see how much the

5 model s hips opened up in less than two weeks. Before undergoing the treatment regimen, there was a noticeable difference in the length of his legs and his elbows came to rest at different heights. To be frank, I would have to say he was inflexible for an athlete. During the 10 days of treatment, I would guide him through both alignment correcting stretches and hip joint activation training. The hip joint activation training consisted of dynamic exercises, such as kicking a heavy bag, high kicks, and sumo stomps. The appropriate number of repetitions and the amount of strength that should be used for these exercises vary from player so this training regimen must be carefully observed. This combination of dynamic exercise and static stretching synergize to have an increased positive effect. Patients will not engage in any heavy training during the treatment period. They will be allowed to exercise to some extent, for example throwing a baseball at a net or swinging a bat to polish their form; however, they should not push themselves any further. Patients are also required to follow a special step-by-step training regimen for about a month or so following the intensive treatment to get back to their normal training level (During this period, they must refrain from running sprints or participating in other running drills and continue their activation and weight training). Coaches and trainers are oftentimes worried that the lack of practice will weaken their players and worsen their technique, but activation training is actually harder than it seems and a good cardiovascular workout. Furthermore, my hip joint treatment trains and improves the biggest muscle in the body, the gluteus maximus, and opens up the body s range of motion in a very short period of time. The surrounding ligaments and muscles will also be placed under a lot of stress so normal exercise should be avoided for some time. I believe that no matter how hard athletes trains, if their hips are misaligned they will not be able to attain the level of success they are hoping for. Also, training at a high level with their hips misaligned will greatly increase the risk of injuring their lower back or knees. I want athletes to realize that if they want to reach the top of their sport, they must start by aiming for a perfect hip joint. According to hip joint theory, when a player gets to the point where they have perfect hips, their performance also undergoes a huge transformation.

6 If you look at the picture data taken of my model, for example, you can see the differences before and after the treatment. His static flexibility vastly improved, and his throwing form developed more of a whip motion. Before the treatment, it was difficult for him to place considerable weight onto his pivot foot. But, after the treatment he could naturally lift his left leg higher and load more weight onto his pivot foot. Above all else, the increased range of motion of his hip joint allowed him to naturally take a wider step and get his hips lower to the ground. Meanwhile, his upper body took the shape of a bow and his right elbow moved closer to its ideal position. His hips moved smoothly and he was able to shift his body weight firmly when planting his left leg. This allowed him to get his release point as close to the batter as possible. Prior to undergoing my treatment, my model would also quickly build up fatigue in his pivot leg while pitching because of the misalignment of his hip joint. But, he said he felt much less tired throwing the same number of pitches after the treatment. Furthermore, he also said that even when he did feel fatigue, it took him much less time to recover afterward. These positive results are not just limited to this athlete s case. Many other pitchers have told me that they feel the quality, speed, and power of their pitches have greatly improved after the treatment. I truly hope that athletes, coaches, and anyone else interested in improving their physical performance realize the importance of realigning their hip joints.

8 似たケースが多いということが分かっています次に生活習慣の変化により日常的に股関節を動かす量が減ってしまったことが考えられます例えばトレイが和式から洋式になったことで腰を落として深くしゃがみ込むという動きをしなくなったこと子どもが外で遊ばず家の中でゲームに興じることが多くなったことなどから股関節の可動域が極端に狭まってきている点も大きな要因として考えられますさらにはそんな子どもたちが小学校低学年 ( スポ少スタート時 ) から急激に運動量が増えたのにもかかわらず徹底したストレッチ指導がなされていない事だと思いますこの時期に動的ストレッチと静的ストレッチが徹底される事が後々の成長期前後でのズレ防止にも繋がると思いますしかし現状はストレッチを軽視されその結果中学校以降になって腰椎ヘルニアや分離症などのスポーツ障害に悩まされてしまうケースも多くなっていますこのスポーツ障害の多くは股関節のズレによって体が硬い選手に起こる骨盤後傾が主因の一つであることが分かっていますそこで私は股関節治療により骨盤後傾の改善や動作姿勢を改善ししなやかな体へと導くことで効率よく動けるようにしこれらの障害を克服するサポートを行っているのですしなやかな体私はそれを完璧な股関節と言っていますがこれこそが長年の治療経験から生まれた股関節理論の根本でもありますこの完璧な股関節とは分かりやすく言えば大相撲の力士たちがやっている股割りの姿をイメージしてもらえれば良いでしょうつまりは両足が 180 度近く開きしっかりと股割りができている人というのは股関節のズレがない ( 少ない ) とも言えるのですただしここで重要になってくるのは股関節のズレは自分自身では完全には治せないということですこれから毎日ストレッチを行えばある程度は柔らかくなり関節の可動域も広がりますしかしズレそのものは本人では治すことができず体の歪みのすべてを解消することは望めませんそこで私は股関節治療によって股関節のズレを整え左右対称に完璧に股関節を開かせることでしなやかな体へと導いていきますさらにアスリートに対しては股関節活性トレーニングを交えながら治療を行う事で神経系の改善や長年にわたって生じた股関節周辺の筋肉じん帯のクセを取り除いていくのですつまりアスリートにおいて股関節の動きの重要性を語るためにはこのズレを解消し完璧な股関節を手にすることが大前提になると私は考えているのですそして股関節とは骨頭などの変形がない限り性別や年齢にかかわらず誰でも 180 度近く開く様に設計された関節だと言えますまた関節が開かなくなっている事で色々な弊害が起こ

9 っていると考えていいのではないでしょうか ( 小見出し 2) ケガをしにくい強い体を手に入れる ( 本文 ) 現在私は多くの学校や競技現場でさまざまな形で講演をさせていただいていますがときにこんな質問を受けることがありますどうして力士や体操選手じゃないのに完璧に股関節を開く必要があるのですか? まさしくこのことが一流選手になれるかどうかの分岐点だと私は考えています最大限のパフォーマンスを発揮する大前提にあるのは自分の体を効率良く動かせるかどうかということつまりそのためには股関節を十分に使い切る必要があるというのはご理解いただけるはずです例えば車で考えてみると股関節とはまさしく足回り ( タイヤ回り ) の役目を担っていますその足回りにズレがあれば車は真っすぐ走ることができませんよねつまりそれは最大限のスピードを発揮することのできない車だと言えますそしてこれは 2 本の足で走る人間の体でも同様なのですまた長年の治療経験から股関節のズレが体のほかの部位にも大きく影響を及ぼし何かしらの問題や痛みを引き起こしていることも分かっています例えば野球では投手を中心に肩の痛みに悩む選手をよく見かけますがこれにも股関節のズレが関係しているケースが多いと私は考えています掲載されている資料写真を見ていただければ分かるように股関節にズレがあり脚長差 ( 足の長さ ) が大きく違う選手というのは必ずと言っていいほど肩の関節にも歪みが発生しています胸の前で両ヒジを合わせてみるとヒジの高さが合わないことが見て取れますこれは股関節の硬い人というのは就寝時に横向きで寝るケースが多くこの長時間の横向き状態が肩関節に大きな負担となっていることが主な原因だと考えられますこのようなことが何年も続くわけですからストレスのかかった関節がズレてしまうのはある意味当然のことなのですつまり選手はその体の歪みを抱えたまま日々のトレーニングで強い負荷を体に課すことによって痛みが発生するのですそしてこれは肩痛だけなく腰痛ヒザ痛などにも言えます

10 そもそも多くの指導者の皆さんが体の柔軟性の重要さを認識し練習時にはストレッチメニューを取り入れていることでしょうしかし一般的に行われているストレッチはウオーミングアップやクールダウンなどを兼ねて行う場合が多く選手それぞれが各々のレベルで体の部位筋肉を伸ばしているに過ぎないように感じます果たしてこれで特に体の硬い選手に対してケガ予防としてのストレッチができているのでしょうか私が考える本来のストレッチとは完璧な股関節があってこそ効果を発揮します長年の治療経験からも股割りができるようにしていく過程で神経系が回復し筋肉の張りや萎縮なども改善されることが分かっています新陳代謝が上がり股関節が開かれることで体のバランスが良くなった選手というのは強い負荷をかけるトレーニングにも自然と耐えられるようになるのですアスリートの故障障害予防については指導者の責任でもあります股関節に問題を抱えた選手というのは高い可能性で体のどこかに故障や痛みを発生させてしまうのです言い換えれば体の硬い選手というのはかなりの確率で股関節に問題を抱えているのです指導者はそのことを理解しできるだけ早期に対処してあげるべきなのではないでしょうか ( 小見出し 3) 股関節集中治療と活性化トレーニング ( 本文 ) では実際の股関節治療について今回は熊本秀学館高の北之園隆生投手をモデルにご説明します当院では 10 日間の集中治療合宿を行っています整復前 ( 治療前 ) と整復後 ( 治療後 ) の資料写真を見比べていただければ分かるとおり北之園選手の股関節はここまで開くようになりました整復前の彼は脚長差を調べるとズレが認められ両ヒジを合わせた高さにも左右のズレがありました当然アスリートとしては硬い体と言わざるを得ませんそして 10 日間股関節のズレを整える整復治療を施しそれに並行して股関節活性トレーニングを行いましたこのトレーニングとはサンドバッグへの蹴り込み蹴り上げ相撲の四股などなのですがその回数や強さなどは選手によって変わってきますので注意

11 が必要ですまたこの動的なトレーニングのインタバールに静的なストレッチ ( 股割り ) を組み入れます動と静の股関節トレーニングを合わせることで相乗効果が得られますちなみにこの治療期間ではこれ以外の強い運動は行いませんある程度のウエイトトレーニングは認めていますが例えばボールやバットを使った練習などはフォーム作りでのネットスローや素振り以外はあまりさせませんまた集中治療後の約 1か月から 1か月半の間は別メニューで段階的に通常のトレーニングレベルにもっていく事が重要になってきます ( この期間はダッシュなど走力トレーニングを控え活性トレーニングやウエイトトレーニングで我慢する必要があるのです ) よく指導者や保護者からは練習不足による体力低下や技術低下を心配されるのですが活性トレーニングそのものは見た目以上にハードであり心肺機能を使いますさらに股関節治療とは人体の中でも一番大きな関節のズレを治し短期間で股関節を開かせていく治療ですかなり大きなストレスが関節はもちろん周辺の靭帯筋肉にもかける事になるためある程度の期間は通常の運動を避けるべきなのですまた私の立場から言わせていただければ股関節がズレたままでハードトレーニングを行っても期待どおりの成果は得られないし腰膝などの怪我に侵される可能性が非常に高くなるはずですいわば完璧な股関節とは一流のアスリートを目指す者にとってのスタートラインだと認識してほしいのです ( 小見出し 4) 実際の動きに見て取れるパフォーマンスの変化 ( 本文 ) この股関節理論に基づき股関節のズレを整えて完璧な股関節を手にいれた選手はパフォーマンスにも大きな変化が期待できます例えば北之園投手の投球フォームを見てもその違いが分かるはずです静的柔軟性の向上はもちろんのことそのフォームにもしなりが出てきているのが見て取れます治療前は軸足の股関節にうまく体重を乗せることができませんでしたが治療後には自然に左足も上がりタメが作れていますそして何よりも股関節が違和感なく開くことで自然とステップ幅も広がり腰の高さも変わっていますそして同時に上半身も弓のように反れ右ヒジも理想に近いトップの位置へと導かれています股関節がスムーズに動くことで踏み込んだ左足にもしっかり
