Outline of Final Research Achievements

Muscle fiber composition is generally classified into two groups, namely fast- and slow-twitch muscle fibres. A high proportion of slow-twitch muscle fibres are related to endurance performance and a high proportion of fast-twitch muscle fibres are related sprint performance. The aim of the present study was to identify genetic polymorphisms that is associated with muscle fiber composition by using genome-wide association study in 212 Japanese general population. We found 146 single nucleotide polymorphisms (SNPs) that could be associated with the proportion of slow twitch muscle fibres from Japanese discovery cohort. Among them, meta-analysis in Japanese and Europeans revealed that 16 SNPs from four gene loci were associated with the proportion of slow muscle fibres.

Academic Significance and Societal Importance of the Research Achievements

世界トップレベルの選手を対象として競技力を左右する筋線維組成を解析すると、短距離系競技に優れた選手は速筋線維の割合が、長距離系競技で優れた選手は遅筋線維の占める割合が高い。また、近年の研究では筋線維組成が糖尿病や高血圧といった生活習慣病にも関連することが明らかになってきている。筋線維組成は遺伝の要因が強く、運動トレーニングによる筋線維組成の変化は小さいと一般的に考えられている。本研究課題で、筋線維組成を規定する遺伝要因を明らかにできれば、遺伝情報を用いた適正種目の選択だけでなく、2型糖尿病や肥満といった疾病リスクに及ぼす影響にも貢献できると考えられる。
