지구성 운동전 감식초 섭취시 에너지기질의 이용 = Persimmon Vinegar Ingestion before Endurance Exercise on Energy Substrates Utilization

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the potential of persimmon vinegar as a functional beverage by analyzing the effects of persimmon vinegar ingestion on the energy substrate during endurance exercise. The healthy male adolescents (n=8) drunk persimmon vinegar ingested trial (PSV) or purified water ingested trial as the control trial (CON) 1 h prior to the exercise with the 60% of maximal oxygen uptake (VO_₂max) for 1 h. The exercise intensity was increased to the 80% of VO₂_max and remained until exhaustion. And the physiological variables blood components and amounts of energy oxidation were analyzed. There was no significant difference between trials in physiological variables and the heart rates after exhaustion were higher in PSV compared to CON. There was no significant difference between trials in blood glucose level while the blood lactic acids decreased significantly in PSV 30 and 60 minutes after onset of exercise. The free fatty acids concentration increased significantly in PSV from 15 minutes to 60 minutes after onset of exercise. The carbohydrate oxidation decreased significantly in PSV from 45 minutes after exercise and on the contrary the fatty acids oxidation increased significantly for the same period. And fatty acids oxidation was higher in PSV compared to C|ON even after exhaustion. The respiratory exchange ratio was lower significantly in PSV compared to CON from 30 minutes to 60 minutes after exercise whereas lower in CON after total exhaustion. The exercise time to exhaustion was 41% longer in PSV compared to CON. These results showed that the persimmon vinegar increase the level of lipids metabolism and decrease sense of fatigue by inhibiting carbohydrate oxidation during moderate intensity exercise suggesting the possibility of using of persimmon vinegar as exercise functional beverage when ingested 1 h prior to the endurance exercise performance.
