PURPOSE: In this study we examine the ergogenic effects of a carbohydrate mouthrinse by assessing muscular strength in a glycogen-lowered state. METHODS: Thirteen males completed baseline strength, watt and VO2 max tests followed by experimental trials with either placebo (PLA) or carbohydrate (CHO) mouthrinses. Glycogen lowering was performed on a cycle ergometer and followed by 3 x 5s isometric knee extensions and 20 isokinetic extensions/flexions. RESULTS: The isometric extension test showed no significant difference in average peak torque (PLA 185.5 ± 41.9 Nm/CHO 183.4 ± 49.0 Nm). Similarly, the isokinetic extension/flexion test showed no significant difference in average peak torque (PLA 105.5 ± 23.0 Nm/CHO 109.1 ± 25.2 Nm). CONCLUSIONS: The CHO mouthrinse had no significant ergogenic effect on muscular strength, and thus did not produce a sufficient neuromuscular response to significantly increase motor output in fatigued participants.
