The increase in performance may be attributed to higher glycogen resynthesis during the recovery period

[7]. However, the carbohydrate-protein supplementation did not show any additional effect compared to isocaloric carbohydrate [28]. On the other hand, consumption of 0.6 g/kg/hr carbohydrate during the 2-hr recovery after a glycogen-depleting MK5108 exercise resulted in similar time to exhaustion in the subsequent endurance exercise, compared to 1.0 g/kg/hr carbohydrate or 0.6 g/kg/h carbohydrate plus 0.4 g/kg/hr protein [29]. The authors concluded that the additional energy, either in buy PRT062607 carbohydrate or protein, did not provide additional effect above 0.6 g/kg/hr carbohydrate during the 2-h recovery period

[29]. With carbohydrate intake of 0.8 or 1.2 g/kg/hr during the 4-hr post-exercise recovery period, the additional protein showed no effect on the running time to exhaustion at 85% VO2max in the subsequent exercise, despite higher insulinemic response [30]. One of the reasons that protein offered no additional benefit may be the higher carbohydrate oxidation rate and similar glycogen utilization rate during the subsequent endurance exercise [31, 32]. The aforementioned studies all focused on endurance exercise. For the first time, this study suggested that consumption of carbohydrate or carbohydrate plus BCAA and arginine during the recovery period had no effect on the performance in the subsequent intermittent high-intensity https://www.selleckchem.com/products/btsa1.html exercise in well-trained wrestlers. It is generally believed that muscle glycogen resynthesis during the first 4 hours of recovery is proportional to the amount of carbohydrate ingested during the period [33]. While some authors have reported increased rates of muscle glycogen resynthesis following the addition of protein to carbohydrate during recovery

periods after glycogen-depleting exercise [17, 34], others have found no such PAK6 effect despite higher insulinemic response induced by protein [35–37]. A recent review suggested that when carbohydrate intake is less than 1 g/kg/hr over the 2-6 hr post-exercise period, the additional protein would increase muscle glycogen resynthesis. On the other hand, when carbohydrate intake is sufficient, i.e. larger than 1 g/kg/hr, the co-ingested protein would not provide additional effect on glycogen resynthesis [38]. Our subjects consumed 0.5 (CHO+AA trial) and 0.6 (CHO trial) g/kg/hr carbohydrate during the recovery period, which may allow the additional protein to result in higher glycogen resynthesis. However, we still found that plasma insulin and glucose concentrations were similar between the 2 trials, indicating that glycogen resynthesis is likely also similar. In agreement to our results, it was reported that consumption of 0.6-0.8 g/kg/hr carbohydrate and 0.25-0.
