초록

철인 3종 경기에 참가하는 선수들은 탈수, 저나트륨혈증, 용혈현상 및 연역반응과 같은 의학적인 문제에 직면할 수 있다. 본 연구는 철인 3종 경기 시 체중의 변화, 나트륨농도 및 혈액성분의 변화를 조사하기 위하여 서로 다른 Olympic Distance Triathlon (ODT)과 Ironman Distance Triathlon (IDT)에 참가한 선수들에게 체중과 나트륨 농도 및 혈액 성분이 어떠한 영향을 미치는가를 연구하였다. 체중은 ODT와 IDT 모두 유의하게 감소하였고, 나트륨 농도는 IDT에서만 증가하였다. RBC, Hb, Hct 및 MCH는 IDT에서 증가하였고, Hct는 ODT에서 감소하였다. IDT에서는 체중의 변화율과 나트륨 농도간의 유의한 상관관계가 있었으며, 체중 감소에 따른 나트륨농도의 증가현상이 나타났다. RBC, Hb 및 Hct의 연화는 거리에 따라 영향을 받는 것으로 조사되었다. 이러한 결과들을 종합해 볼 때 철인 3종 경기와 같은 장시간 지속되는 운동 시 체중 변화가 나트륨 농도에 영향을 미치는 것으로 파악되었으며, 경기 거리에 따른 혈액 성분의 변화에 차이는 있었지만 이러한 변화는 모두 정상범위인 것으로 나타났다.

This study examined how differing triathlon durations effect weight, serum sodium concentration, and hematological levels, and investigated relationships between these variables and finishing time as well as between body weight changes and serum sodium following Ironman distance triathlons (IDT) and Olympic distance triathlons (ODT). All eight athletes successfully completed ODT and IOT. We found that the mean body weight decreased following both IDT and ODT and that serum sodium was significantly (p<0.05) increased immediately after IDT, RBC, Hb, Hct, and MCH were significantly (p<0.05) increased immediately after IDT. Hct was significantly (p<0.05) decreased immediately after ODT. MCHC was significantly (p<0.01) increased immediate1y after ODT. In IDT, the percentage of change in body weight correlated to the percentage of change in serum sodium concentrations (r=0.75, p=0.05). In conclusion, our srudy showed that serum sodium concentraion increased in IDT and maintained in ODT, despite significant body weight loss during the races. The percentage of change in body weight was related to serum sodium concentration but unrelated to performance in the triathlon. The changes of RBC, Hb, and Hct values from two different length triathlons were depending on race distance.
