L-arginine과 L-aspartate 섭취가 운동 중 에너지 기질 이용 및 운동수행능력에 미치는 영향

Abstract

This thesis aims to study the effect of L-arginine & L-aspartate administration in the use of energy substrates and the physical performance. The single intake of L-arginine and simultaneous administration of L-arginine + L-aspartate have an effect on decreasing RPE and the concentration of glucose, lactate and ammonia. They also have an effect on increasing the concentration of glucagon and extending the duration of exercise. These effects are remarkably shown while simultaneous administration of L-arginine + L-aspartate. While the concentration of free fatty acid is decreased during the single intake of L-arginine, there is no change during simultaneous administration of L-arginine + L-aspartate. I also examined the aspect that the L-arginine and L-arginine + L-aspartate never influence the concentration of insulin. In conclusion, we can see that the combined treatment of L-arginine + L-aspartate can decrease the concentration of lactate and ammonia and RPE more than the single administration of L-arginine while exercising. The former also has beneficial effects on increasing the concentration of glucagon and extending the time of exercise duration.
