초록

본 연구는 과당 위주의 스포츠음료 투여가 최대운동부하시 심폐기능과 젖산 및 염증반응에 미치는 영향에 대해 비교 분석하기 위해 실시되었다. 연구대상자는 D 대학교 체육학과 학생 8명으로 구성하였으며 실험시기를 2차로 나누어 스포츠 음료 투여 전과 투여 후 시기에 심폐기능과 젖산 및 염증반응 등을 비교 분석하였다. 본 연구의 결과 스포츠 음료 섭취 전과 섭취후 운동시간과 V02max, AT HRmax가 유의하게 증가하였고(p<0.05), 스포츠 음료 투여 후 회복기 20분에서 젖산 농도가 유의하게 감소되었다(p<0.05). 따라서 고강도 최대운동 전 과당위주의 스포츠 음료 투여는 운동지속시간을 늘려주고 VO2max를 높여주며, 운동 후 피로물질인 젖산축적의 빠른회복에 도움을 줄 수 있는 것으로 사료된다. 비록 본 연구에서 염증 반응에 대한 효과를 완벽하게 규명하지는 못했지만 스포츠 음료 투여시 CRP의 농도가 감소하는 경향이 나타나 염증반응 개선에도 어느 정도 영향을 미칠 수 있을 것이라 생각된다. 추후 과당위주의 스포츠 음료투여시 염증 반응에 대한 다양한 운동 강도와 상황에서의 기전적 연구가 수행되어져야 할 것이다.
