学生長距離ランナーを対象に10000mレース翌日に軽運動をする群とプールでアクアコンディショニングをする群にわけ、疲労回復の影響を検討した結果、アクア群はCKがレース24時間後から48時間後の間に有意に低下し、アクアコンディショニングは筋損傷と柔軟性の回復に有効な手段である可能性が示唆された。

Subjects in control group, the peak plasma creatine kinase activity was observed at 1 d after the race, and correlated with post-race WBC. The post-race elevation of CK activity was suppressed by WGH intake in a dose-dependent manner. In well-trained distance runners, after a half-marathon, delayed-onset muscle injury peaked at 1 d after the race and was suppressed by post-race intake of WGH in a dose-dependent manner.

Fifteen long-distance runners were allocated into CT or placebo groups, and test food was ingested for 10 days prior to the start of training camp. Clinical examinations were performed before and after the training camp. The results indicated a significantincrease in high-sensitivity C-reactive protein (hs-CRP) and neutrophil count in blood, as well as a decreasing tendency of lymphocytes in the placebo group, but not the CT group. These observations suggested that ingestion of CT contributes to suppress the changing rate of inflammatory response, prevents decreasing rate of immune function, and prevents infection and reduces symptoms when infected associated with continuous intense exercise.
