骨格筋の修復と再生に与えるマッサージの影響

Enhanced skeletal muscle regrowth and remodelling in massaged and contralateral non-massaged hindlimb

https://www.ncbi.nlm.nih.gov/pubmed/29090454


J Physiol. 2018 Jan 1;596(1):83-103. doi: 10.1113/JP275089. Epub 2017 Dec 1.

Miller BF, Hamilton KL, Majeed ZR, Abshire SM, Confides AL, Hayek AM, Hunt ER, Shipman P, Peelor FF, Butterfield TA, Dupont-Versteegden EE

(Butterfield TA,2008)などのデータから、

マッサージ(CCL)は運動後の筋肉の回復に効果があるとされている。

(Waters-Banker C,2014)ではマッサージの影響は実施した側に出るとしているが、

ウエイトトレーニングなどの実験では、

負荷をかけた反対側にも影響が出ていることが知られる。

本研究ではラットを用い筋を委縮させ、

マッサージが実施した脚と反対脚にも影響が出ることを調べた。

結果、マッサージをした群は何もしない群と比較して筋肉の肥大が有意に見られた。

Itg7aはマッサージ群において有意に上昇した。

マッサージを実施していない脚も、何もしていない脚に比べて有意に筋肉が肥大した。

筋肉の合成が増加した理由は翻訳の増加であろうと考えられる。

委縮させた後の期間において、タンパク質合成とDNA合成の速度はマッサージした側で大きかった。

これに関してはCCLによって衛星細胞が増殖するように導いたのであると提案する。



なるほどなぁ、という感じで面白い論文でした。

人間でどこまで効果があるのかは不明ですが、

言われてみればそうだよね、

というのが多くありました。

マッサージによる交感神経などの刺激といった点での継続調査が必要でしょうが、

術後や運動が出来ない状態における効果としては面白そうです。

Irisinの投与は筋ジストロフィーの改善に効果がある

Irisin treatment improves healing of dystrophic skeletal muscle.

https://www.ncbi.nlm.nih.gov/pubmed/29228710




Oncotarget. 2017 Oct 6;8(58):98553-98566. doi: 10.18632/oncotarget.21636. eCollection 2017 Nov 17.

Reza MM, Sim CM, Subramaniyam N, Ge X, Sharma M, Kambadur R, McFarlane C

筋肥大に効果的、体脂肪の減少にも効果的と言われるIrisinが筋ジストロフィーの患者にも効果がありそうです、という内容。

無料ですので過去の論文を調べるのに便利ですね。

(14)の論文はミオスタチンが減ることでIrisin濃度が高まることを報告している、

線維化にも影響があるという点を考えると、

Irisinはもっと注目されるべき話ですね。

なお、Irisinがたくさん含まれた特性ドリンクを2017年は複数人に飲んで頂きましたが、

あれの効果がどれほどあったのか。
