Abstract

　きわめて効率良く筋肉を増強させることができる方法を提供する。使用者の四肢の少なくとも何れか一つにベルトを巻き付け所定の加圧力を付与して使用者の筋肉の血流制限を行いつつ水の抵抗力を使用者に作用させる筋肉増強方法である。使用者の筋肉の血流を制限することにより使用者の成長ホルモンの分泌を促すことに加え、陸上よりも少ない動きで効率良く負荷を与え、これらの相乗作用によりきわめて容易に筋肉を増強させる。

Description

筋肉増強方法
　本発明は、筋肉増強方法に関する。
　従来より、血流制限による負荷を筋肉に付与することにより効率良く筋肉の増強を行うことができる加圧筋力トレーニング方法が提案され、実用化されている（例えば、特許文献１参照）。かかる筋力トレーニング方法においては、緊締具で使用者の四肢（腕や脚）の所定部位を締め付けて筋肉に加圧力を付与する筋肉増強器具が使用されている。
特許第２６７０４２１号公報
　ところで、現在においては、水中で作用する抵抗力や浮力を利用したトレーニングやリハビリテーションに関する方法が提案されている。アスリートが従来採用している水中トレーニング方法としては、水中で大きい抵抗力を発生させる物体（例えばバケツ）をロープを介して身体に取り付けた状態で泳ぐ方法や、水の流れに逆行するように泳ぐ方法等が採用されており、このような方法によれば、使用者（トレーニングを受ける者）に意図的に負荷を与えることができる、とされている。
　しかし、上記したような従来の水中トレーニング方法では、大掛かりな道具や設備が必要となる割には、使用者の血中乳酸濃度を効率良く増大させることができないという問題があった。筋肉を増強させるためには、脳下垂体から通常時よりも多くの成長ホルモンを分泌させる必要があり、このためには、効率良く血中乳酸濃度を増大させる必要がある。本願発明者は、前記した特許文献１に記載されたような従来の加圧筋力トレーニング方法と、水中でのトレーニングに関する方法と、を組み合わせることにより、きわめて効率良く筋肉を増強させることができることを新たに見出した。
　また、水中は、浮力が働くために比較的楽に身体を動かすことができるという点で、いわゆる肥満体型を有する者や筋力が衰えた者がトレーニングやリハビリテーションを行い易い環境ではあるものの、浮力が働くがゆえに使用者に充分な負荷を与えることができず、トレーニングやリハビリテーションの効果があがり難いという問題がある。本願発明者は、このような問題についても、従来の加圧筋力トレーニング方法と、水中でのトレーニングに関する方法と、を組み合わせることにより解決できることを発見した。
　本発明は、きわめて効率良く筋肉を増強させることができる方法を提供することを目的とする。
　前記目的を達成するため、本発明に係る方法は、使用者の筋肉を増強させる方法であって、使用者の四肢の少なくとも何れか一つにベルトを巻き付け所定の加圧力を付与して使用者の筋肉の血流制限を行いつつ水の抵抗力を使用者に作用させるものである。
　かかる方法を採用すると、使用者の四肢の少なくとも何れか一つにベルトを巻き付け所定の加圧力を付与して使用者の筋肉の血流制限を行うことにより、使用者の成長ホルモンの分泌を促進することができる。また、このような血流制限を行いつつ、使用者を水中に入れて水の抵抗力を使用者に作用させることにより、陸上では得られない負荷を使用者に付与することができる。すなわち、使用者の筋肉の血流を制限することにより、従来の水中トレーニング方法のように大掛かりな道具や設備を採用することなく使用者の血中乳酸濃度を増大させて成長ホルモンの分泌を促すことができることに加え、陸上よりも少ない動きで効率良く負荷を与えることができ、これらの相乗作用により、きわめて容易に筋肉を増強させることができる。さらに、水中では浮力を得ることもできるため、筋力が衰えて自身の体重を支えるのが困難である使用者であっても、本方法を使用して容易に筋肉を増強させることができる。
　本発明によれば、きわめて効率良く筋肉を増強させることができる方法を提供することが可能となる。
本発明の実施形態に係る筋肉増強方法で使用されるベルトの正面図である。 図１に示すベルトの背面図である。 図１に示すベルトの平面図である。 図１に示すベルトの底面図である。 図１に示すベルトの右側面図である。 図１に示すベルトの左側面図である。 図１のＡ－Ａ部分の断面図である。 図１に示すベルトの使用状態を示す図である。 本発明の実施形態に係る筋肉増強方法を説明するためのフローチャートである。
　以下、図面を参照して、本発明の実施形態について説明する。
　まず、図１～図８を用いて、本発明を実施形態に係る筋肉増強方法（筋肉トレーニング）で使用されるベルト１について説明することとする。
　本実施形態におけるベルト１は、使用者の四肢の少なくとも一つに巻き付けられて筋肉に加圧力を付与する帯状の部材であり、撥水性、耐水性及び速乾性を有するとともに伸縮性を有する素材（例えばネオプレンゴム）で構成されている。このため、本実施形態におけるベルト１は、水中での運動に好適なものである。
　ベルト１の長さ及び幅は、使用者の体格や巻き付ける部位に応じて適宜設定することができる。ベルト１は、複数（例えば筋肉トレーニングを行う者（使用者）の両手、両足に対して加圧を行えるように４つ）採用することができる。なお、ベルト１の数は必ずしも４つである必要はなく、一つ以上であれば幾つでも構わない。腕用のベルト１と脚用のベルト１は、必ずしも同数である必要はない。
　ベルト１の外面（外側に露出する面）２には、図１及び図８に示すように、面ファスナ１０が設けられている。面ファスナ１０は、筋肉に加圧力を付与した状態におけるベルト１のループ形状を維持するものである。面ファスナ１０を設ける位置はベルト１の長さ等に応じて適宜設定することができる。ベルト１の内面３に面ファスナ１０を設けてもよい。
　ベルト１の一方の端部４には、バックル２０が取り付けられている。バックル２０は、ベルト１の巻付けの際にベルトの他方の端部５を通してベルト１を折り返すためのものである。バックル２０の内面（使用者の皮膚側に位置する面）側には、図２～図４に示すように、柔軟な素材（例えば皮や布）で構成された小片３０が配置されている。この小片３０によって、ベルト１を締め付けて加圧力を付与する際に、使用者の皮膚が（バックル２０の中に通されたベルト１の一部とともに）バックル２０内に巻き込まれることを防ぐ。
　ベルト１のバックル２０と反対側の端部５には、ベルト１の幅と同じ幅（乃至ベルト１の幅より若干狭い幅）の帯状部材４０が接続されている。帯状部材４０の外面（外側に露出する面）には面ファスナ４１が設けられており、この面ファスナ４１は、ベルト１の中央部付近に設けられた環状部材５０の面ファスナ５１に結合するようになっている。これら帯状部材４０と環状部材５０とが面ファスナ４１・５１を介して結合することにより、水中でもベルト１がその形状を維持することができるようになっている。なお、環状部材５０のベルト１上の位置は変更できるようになっている。
　次いで、図９のフローチャート等を用いて、本実施形態に係る筋肉増強方法について説明する。
　まず、使用者は、筋肉増強を望む筋肉を含む四肢の少なくとも一つ（例えば上腕二頭筋を含む左上腕）の心臓に近い部位にベルト１を巻き付け、ループ形状を作る（ベルト巻付工程：Ｓ１）。この際、ベルト１の一方の端部４に取り付けられたバックル２０に、帯状部材４０とベルト１の他方の端部５とを通してベルト１を折り返す。
　次いで、使用者は、バックル２０に通した帯状部材４０を把持しながらベルト１を締め付けることにより所定の加圧力を付与した状態で、面ファスナ４０を用いてベルト１０のループ形状を維持する（加圧力付与工程：Ｓ２）。加圧力の大きさは、使用者の年齢、性別、運動経験等に応じて適宜設定することができる。
　その後、使用者は、ベルト１のループ形状を維持したまま（ベルト１０が筋肉に付与する加圧力を一定に維持したまま）、水中で運動を行う（水中運動工程：Ｓ３）。水中運動工程Ｓ３により、水の抵抗力や浮力が使用者に作用することとなる。水中運動の種類や継続時間は、使用者の年齢、性別、運動経験等に応じて適宜設定することができる。
　以上説明した実施形態に係る筋肉増強方法においては、使用者の四肢の少なくとも何れか一つにベルト１を巻き付け所定の加圧力を付与して使用者の筋肉の血流制限を行うことにより、使用者の成長ホルモンの分泌を促進することができる。また、このような血流制限を行いつつ、使用者を水中に入れて水の抵抗力を使用者に作用させることにより、陸上では得られない負荷を使用者に付与することができる。すなわち、使用者の筋肉の血流を制限することにより、従来の水中トレーニング方法のように大掛かりな道具や設備を採用することなく使用者の血中乳酸濃度を増大させて成長ホルモンの分泌を促すことができることに加え、陸上よりも少ない動きで効率良く負荷を与えることができ、これらの相乗作用により、きわめて容易に筋肉を増強させることができる。さらに、水中では浮力を得ることもできるため、筋力が衰えて自身の体重を支えるのが困難である使用者であっても、本方法を使用して容易に筋肉を増強させることができる。
　なお、近年においては、加圧（血流制限）トレーニング方法の研究が進められており、適度な加圧（血流制限）を行うことによって脳下垂体から通常時よりも多くの成長ホルモンが分泌され、この成長ホルモンが筋肉の増強以外にも好ましい影響を身体に与えることが明らかになっている。このため、加圧（血流制限）トレーニング方法が医療やリハビリテーションの分野に応用されつつある。本発明に係る筋肉増強方法は、この「加圧（血流制限）」に「水中運動」を組み合わせたものであり、さらなる成長ホルモンの分泌を促すことができるものであるため、医療やリハビリテーションの分野にも充分に適用することが可能であり、各種疾病（糖尿病、高血圧、高脂血症等）の予防や治療を実現させることができる。
　本発明は、以上の実施形態に限定されるものではなく、この実施形態に当業者が適宜設計変更を加えたものも、本発明の特徴を備えている限り、本発明の範囲に包含される。すなわち、前記実施形態が備える各要素及びその配置、材料、条件、形状、サイズ等は、例示したものに限定されるわけではなく適宜変更することができる。また、前記実施形態が備える各要素は、技術的に可能な限りにおいて組み合わせることができ、これらを組み合わせたものも本発明の特徴を含む限り本発明の範囲に包含される。
