Outline of Final Research Achievements |
This study examined the recovery of stiff muscles by the application of methods to reduce muscle stiffness. In anticipation of the social implementation of the results, we adopted methods that enabled the self-management of the condition adequately. The result of stretching the stiff muscles of athletes who participated in the full-marathon race confirmed that repeated stretching tends to accelerate recovery. Regarding massage, it was shown that self-massage using a foam roller, which is highly effective in expanding the range of motion of joints, was effective. These findings are direct evidence that their methods may accelerate the process of stiff muscle recovery.

Academic Significance and Societal Importance of the Research Achievements |
健康維持増進のために行う走る市民ランナーは推計964万人とされるが、ジョギングやランニングによって骨格筋は一時的に硬化し、フルマラソンなどでは1週間が経過してもなお回復しない筋もある。本研究は、この回復を加速させる方法を探るものであった。セルフで実施可能なストレッチングやフォームローラーは硬さを低減させる可能性があった。損失した水分を補うとともに適切なケアを欠かさなければ、回復は加速できる。
