Outline of Final Research Achievements

The present study aimed to confirm relationship between skin-gas NO concentration and PWV(pulse wave velocity) during 60%HRmax cycle exercise.
Significant negative relationships were found between skin-gas NO concentration and PWV in this study. These results suggests that an increase in shear stress on vessels might be much more effective for an increase in skin-gas NO concentration during the whole body exercise. Furthermore, sympathetic nervous activity, circulating hormones, exercised muscle-derived metabolites including reactive oxygen species might also affect the production of NO during the exercise. Thus increased NO production during exercise decreased PWV.

Academic Significance and Societal Importance of the Research Achievements

皮膚から放出されるガス(皮膚ガス)の中にNOが含まれることを発見し、高感度、高精度な皮膚ガス中NO濃度分析システムを構築することに成功している(平成18-20年度科学研究費補助金 基盤研究C)。皮膚ガス中NO濃度測定は、非侵襲かつ非観血的で、非常に微量なガスから瞬時に実施できるという特徴がある。また、これまでに行ってきた測定では、ヒトの皮膚ガス中NO濃度の再現性は高く、生体情報モニターとして安定した成績を得られることを確認している。このように、皮膚ガスの研究は他では行われていないため学術的独自性がある。
