Outline of Final Research Achievements

Though a longitudinal survey (study 1) and intervention (study 2), this study examined whether the associations of affective motivation with exercise behavior were moderated by dopaminergic polymorphisms. Treating affective attitude as the index of affective motivation and weekly exercise time as the index of exercise behavior, this study analyzed the data obtained from both studies. In results, while study 1 supported the moderating roles of dopaminergic polymorphisms, study 2 did not support the roles.

Academic Significance and Societal Importance of the Research Achievements

健康増進には運動が重要だが、運動は習慣化が難しいため、運動の習慣化を効果的に支援する方法論を確立することの社会的意義は自明である。この方法論を確立する上では、個々人の特性に応じて運動習慣の支援を個別最適化する仕組みの構築、すなわち、“運動習慣のオーダーメイド支援”の構築を目指すことが有効だろう。本研究は、遺伝特性の観点から、“運動習慣のオーダーメイド支援”の構築を目指す芽生え期の研究である。
