Abstract

The purpose of this study was to investigate the effect of bicarbonate intake on blood variables during high-intensity training of sprinters. 30 male/female elites with more than 3 years of experience that are registered to S city as a sprinter was categorized into three groups: control group, training group, and HCO3- and training group. Training group and HCO3- and training group went through a high-intensity exercise program (80-90% HR max) which escalated every 2-3 weeks, for 90 minutes at a time, 5 days a week, 8 weeks in total. HCO3- and Training group took in 300mg of bicarbonate per one kilogram of body weight, in 90 minutes before the start of the high-intensity exercise program, once a day for 8 weeks. As a result of the study, the effect of bicarbonate intake on blood variables during high-intensity training of sprinters showed a positive effect on the increase of pH and the decrease of lactic acid in HCO3- and training group. Also, the increase of Ca2+, Na+, K+ was shown in training group and HCO3- and training group, whereas there were no indications of significant change in Mg2+ in all three groups. It can be confirmed that the intake of bicarbonate during high-intensity training shows effective changes in the increase of pH and the decrease in lactic acid among changes in blood variables. Therefore, it can be seen that the intake of bicarbonate during high-intensity exercise is effective in improving exercise capacity.

본 연구는 단거리 달리기선수의 고강도 훈련 시 중탄산염 섭취가 혈액변인에 미치는 영향 규명하는데 연구의 목적이 있다. S시 남·여 단거리달리기 선수로 등록된 운동경력 3년 이상의 엘리트 선수 30명을 대상으로 통제집단, 훈련집단, 중탄산염 투여와 훈련집단의 세 집단으로 설정 후, 고강도 운동프로그램은 통제집단과 중탄산염 투여와 훈련집단을 대상으로 80-90%HRmax 운동강도를 2-3주마다 증가시키며, 총 8주간, 주 5일, 1회 90분 실시하였다. 중탄산염 섭취는 중탄산염 투여와 훈련집단을 대상으로 체중 1kg당 300mg을 고강도 운동프로그램 시작 90분 전 1일 1회 8주간 섭취하였다. 연구결과, 단거리달리기 선수의 고강도 훈련 시 중탄산염의 섭취가 혈액변인에 미치는 효과는 중탄산염 투여와 훈련집단에서 수소이온농도의 상승과 젖산의 감소에 긍정적인 효과가 나타났으며, Ca2+, Na+, K+은 훈련집단과 중탄산염 투여와 훈련집단에서 유의한 증가가 나타났다. Mg2+은 세 집단 모두에서 유의한 변화를 나타내지 않았다. 고강도 훈련 시 중탄산염의 섭취가 혈액변인의 변화 중 수소이온농도의 증가와 젖산의 감소에 효과적인 변화가 나타나는 것을 확인 할 수 있다. 따라서 고강도 운동 시 중탄산염의 섭취가 운동능력의 개선에 효과적임을 알 수 있다.
