Outline of Final Research Achievements

This study investigated that whether blood glucose level after meal decreased by the short-term static stretching. We also investigated that acute effect of stretching on vasodilation in stretched arm and arterial elasticity index (CAVI). Blood glucose level after meal decreased by the acute short-term stretching. There was no significant increase in nausea, fatigue scale and blood oxidative stress maker by the stretching. Therefore, the stretching would be effective exercise therapy for blood glucose management after meal. The stretching enhanced muscle metabolism at the stretched site and caused vasodilation of brachial arteries. On the other hand, arterial elasticity index did not improve by the stretching.

Academic Significance and Societal Importance of the Research Achievements

食後に行う座位姿勢での10分間程度のストレッチング（柔軟運動）が，血糖値上昇の抑制に効果があり，疲労感と吐き気を伴うことなく実施できたことから，食後の血糖値管理のための運動として利用可能であると考えられた．このストレッチングは関節への負担が少なく，呼吸循環器に対しても過度の負担をかけないで手軽に実践できることから，糖尿病の予防改善のための運動療法として広く活用が期待できる．
