탈진적인 운동 후 초코우유섭취가 피로회복에 미치는 영향 = Effects of Chocolate Milk Ingestion After Strenuous Exercise on Fatigue Recovery

국문 초록 (Abstract)

이 연구는 고강도 탈진적인 윙게이트 운동 후 초코우유 섭취가 2시간의 회복기 동안 피로회복에 미치는 영향을 알아보고자 하였다. 6명의 피험자를 대상으로 하였으며, 3회의 반복적인 윙게이트 운동을 통하여 피로를 유발한 후 물, 초코우유, 스포츠음료를 15분 후에 섭취시켰다. 혈액은 운동 전, 운동 후, 휴식 30분, 60분, 120분에 각각 채혈하였으며, 혈중 대사기질을 분석하였다. 회복 120분이 경과되었을 때, 4회째의 윙게이트 운동을 실시하여 회복율을 조사하였다. 호흡수, 산소포화도, 심박수 역시 측정하였으며, 유의한 변화는 나타나지 않았다. 최대파워/체중과 총일량은 초코우유와 스포츠음료가 물에 비하여 유의한 윙게이트 파워의 회복을 보였다(p<.05). 혈중 대사기질은 집단간 유의한 차이가 없었다. 이러한 결과는 고강도의 탈진적인 운동 후 초코우유 섭취가 스포츠음료와 같이 피로회복을 촉진시킨다는 것을 시사하고 있다. 또한 섭취량의 일반화를 위한 추가연구가 필요하다고 생각된다.

We investigated the effect of chocolate milk (CM) ingestion after the strenuous Wingate exercise on fatigue recovery for 2-h. For this, six healthy male adolescents were subjected to the experiment. They were performed 3-times repeated Wingate exercise to induce fatigue and then they ingested water, CM, and sports drink (SP) after 15 min of the exercise. Blood was obtained at the pre-, post-exercise, 30 minutes, 60 minutes, 120 minutes, respectively and blood metabolites were analyzed. When recovery over 120 minutes, the 4th Wingate exercise was tested for calculating Wingate power recovery ratio at the 1st:4th of the test. Breathing frequency, oxygen saturation, and heart rate were also measured, however, did not showed significant changes. Wingate power recovery ratio of peak power per body weight and total works was significantly higher in CM and SP than water (p<.05). Blood metabolites did not show the significance among groups. These results suggested that chocolate milk ingestion after strenuous exercise facilitates fatigue recovery.
