ローテーターカフ筋 4つの覚え方  A formula for memorizing muscle groups in the shoulder rotator

Which exercise is contraindicated for persons with impingement syndrome of the shoulder rotator cuff muscles ?

This is one of discussion topics for a study group of ACSM certified Exercise Physiologist, which I retrieved from their internet site, and the following is my answer which I posted on their site. What I learned newly through this discussion is ... as you can see in my post, how to memorize names of muscles that constitute the shoulder rotator muscles. A key word for it is SITS, which is an acronym of the four muscles in the shoulder rotators,  1), Supraspinatus, 2) Infraspinatus, 3) Teres minor, and 4) Subscapularis.

1), Overview of the rotator cuff muscles and impingement syndrome.
The rotator cuff muscle group is most important in maintaining the humeral head in its proper position within the glenoid cavity. The acronym SITS may be used in learning the names of the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles must possess not only adequate strength but also a significant amount of muscular endurance to ensure their proper functioning, particularly in repetitious overhead activities such as throwing, swimming, and pitching.
When these types of activities are conducted with poor technique, muscle fatigue, or inadequate warm-up and conditioning, the rotator cuff muscle group fails to stabilize the humeral head in the glenoid cavity, resulting in further rotator cuff problems such as tendinitis and rotator cuff impingement within the subacromial space (Floyd, 2012).

2), Contraindication and recommended exercises for the shoulder impingement syndrome.
Overhead pressing exercises such as shoulder press and all forms of bench press exercise should be used cautiously. The decline bench press stresses this area the least, therefore may be an appropriate exercise choice in reintroduction of the bench press.
The upright row should also be used with caution, as rowing too high (elbows up too high) may exacerbate the impingement type pain.
Clients who have had impingement syndrome should concentrate on continued rotator cuff and scapular exercises. Multiple types of rowing exercises targeting the rhomboids and middle and lower trapezius, especially focused on scapular retraction and depression, are recommended (Coburn & Malek, 2012).

これは、ACSM エクササイズ・フィジオロジストの自主勉強グループのサイトで出題された課題トピックの一つです。上記がサイト上に記載した僕の解答です(ご覧のとおり、自分自身の書いた回答をコピペしました 笑)


S     supraspinatus  (棘上筋)
I     infraspinatus    (棘下筋)
T     teres minor      (小円筋)
S     subscapularis  (肩甲下筋)

エクササイズ イズ メディシン Exercise is Medicine

the word/concept "Exercise is Medicine" is beginning to draw people's attention recently in japan too. Correctly speaking, EIM is American College of Sports Medicine's new champaign/framework to heighten people's awareness about the importance of physical activity and regular exercise habits in terms of disease prevention especially non-communicable diseases. Also, better mutual understanding between health & fitness professionals and medical professionals is an important part of EIM. As a credentialed EIM fitness professional myself, I would like to introduce this new framework in japanese language as well below.
for details please refer to this website http://exerciseismedicine.org/

最近、「エクササイズ イズ メディシン」というキーワードで僕のブログを訪問して下さる方々が少しづつ増えているようですので、本日は、このエクササイズ イズ メディシンとは何かご紹介します。

直訳すれば、「運動は薬だ」ということですね。正確に言えば、運動は状況によっては、従来の医療(投薬など)を補完する上で生活習慣病や障害の予防効果をある程度見込める可能性がある、ということですね。皆さんご承知にように、若年層から中年層では運動不足により肥満やメタボリックシンドロームなどが健康問題になりつつあります。高齢層では加齢に伴う運動機能の減少、転倒の危険性、骨粗鬆症、認知機能の減少などが社会問題になりつつありますね。どこの国も、医療費や健康保険の財源などは非常に厳しい状態にあります。 となると、運動や生活習慣の改善を通して病気や障害を予防しましょうというのがとても大切ですね。


エクササイズ イズ メディシンとは、こういった側面への理解・啓蒙を高めるために、米国スポーツ医学会(ACSM)が主体となって提唱しているキャンペーンというか枠組みです。この枠組みは2007年に開始されましたが、ようやく最近、日本でも少しづつ注目を集めつつあります。この枠組みを健康・フィットネス・医療関係の方々に広めていく上で、ACSMは米国エクササイズ評議会(ACE) および メディカル・フィットネス・アソシエーション(MFA) と提携して推進しています

私はACSM認定のフィットネス指導員ということもあり、このエクササイズ・イズ・メディシン(略称 EIM)の認定を取得しております。詳しい情報は上記のリンクからウエブサイトをご覧ください

in the present society of aging population, prevention of senile dementia is one of important health problems, especially in my country Japan, more than 25 of the current population is 65 years old or older. a result of latest research about brain aging and exercise was published on CNN (original article was publised on Neurology Journal) http://edition.cnn.com/2016/02/15/health/poor-fitness-smaller-brain/index.html
the following is my japanese translation of this article

ボストン大学・医学部 ニコール・スパルターノ研究員らが神経学の学術誌 Neurologyの電子版に発表した記事

概要 中年期における運動習慣(有酸素系の機能など)が約20年後の脳の老化に関与している可能性あり

実験内容 被験者1500名(平均年齢40歳で認知症や心臓病のない人)がトレッドミル(いわゆるウォーキングマシン)にて歩行またはランニングし心肺機能を測定。そして、20年後にMRIで脳の容積などを測定し、中年期の有酸素機能と高齢期における脳の老化や萎縮の関連性を調査

スポーツ心理学に関する新聞記事 - how pro footballers control pre-game nervousness

one of my ex classmates is currently studying sport and performance psychology, and the link below is an article she shared on her social newtworking site. that is about how NFL players control pre-game nervousness and anxiety. it is supposed to be a good article for introducing many of you to the world of sport psychology, besides the concept can be applied to your everyday life as well, so I would like to share it on my blog as well. enjoy reading it !
ちなみに、スポーツ選手の心理面・精神面のサポートやトレーニングを、日本では、メンタル・トレーニングとかメンタル・トレーナーなどと称していますが、私の知る限り、米国ではそのような表現はまずしないようです。やや堅い表現になりますが、心理面へ働きかける方法ならば、psychological intervention などと言います。心理面のサポートをする専門家で学位を持った人は sport psychologist などと称されます

ウェルネス・コーチングとは? what is wellness coaching ?

what I majored in through the post-master's course is wellness coaching. probably the word wellness coaching is an unfamiliar word to many of you, I guess. according to the textbook Coaching psychology manual, coaching is the art of creating an environment, through conversation and a way of being, that facilitates the process by which a person can move toward desired goals in a fulfilling manner (Moore & Tschannen-Moran, 2010). so to speak, wellness coaching is a kind of coaching psychology for health and fitness professionals. and it will become one of major topics in the health & fitness industory in the near future.
