“Introduction Carbohydrate availability

is one of the crucial factors for performance in endurance [1] and high-intensity intermittent exercise [2]. It has been well-documented that carbohydrate supplementation before a single-bout of endurance [3] and

high-intensity intermittent exercise [4] could improve the performance. In real circumstances, many athletes undergo more than 1 training session per day. In addition, many competitions require athletes to participate Epacadostat in vitro in multiple events in a single day. Therefore, adequate nutritional strategies during the short-term post-exercise recovery period may be critical for the performance in subsequent exercise. Several studies have shown that ingestion of protein with carbohydrate after exercise increases muscle glycogen resynthesis rate, compared to the same amount of carbohydrate [5, 6]. The increased muscle glycogen recovery may lead to the improved performance during subsequent endurance exercise [7]. Muscle glycogen resynthesis after exercise consists of two phases. The initial insulin-independent phase that lasts approximately 1 hour has a higher resynthesis rate. It is followed by an insulin-dependent phase with a lower rate that lasts several hours [8]. Previous studies have suggested that branched-chain amino acids (BCAA) and arginine may help improve both phases. Studies in rats have shown that BCAA could stimulate insulin-independent

glucose uptake in skeletal muscle by increasing the translocation of glucose transporter (GLUT)-4 C-X-C chemokine receptor type 7 (CXCR-7) and GLUT-1 to the sarcolemma [9]. Leucine also activated glycogen synthetase via activation of mammalian target of rapamycin (mTOR) signals in isolated muscles [10]. Isoleucine increased insulin-independent glucose uptake and glycogen synthesis in C2C12 myotubes [11]. In addition, nitric oxide (NO), a product of arginine, could increase the insulin-independent expression and translocation of GLUT-4 in rat skeletal muscles [12]. The vasodilation effect of arginine could increase blood flow and substrate delivery to the muscle and further increase glycogen recovery [13]. BCAA and arginine may also facilitate the insulin-dependent phase by inducing insulin secretion [14, 15].
