Effects of Carbohydrate Mouth Rinse on Glycogen Reduced 5k Run Performance Trial
Studies suggest there may be ergogenic effects of carbohydrate mouth rinsing on neuromuscular stimulation to enhance performance of muscular endurance. The purpose of this study was to compare the effects of carbohydrate mouth rinsing or non-caloric placebo on glycogen reduced individuals’ 5k run time. Following baseline testing and a full familiarization trial, randomized double blind experimental trials were completed with either a non-caloric artificial sweetener placebo or a 10% maltodextrin mouthrinse. Experimental trials included an established cycle ergometer glycogen lowering protocol, an isokinetic/isometric assessment of strength, followed by a 5k run for time completed on a treadmill. The 5k run showed no significant difference (p>0.05) between the treatment conditions (CHO 5k: 23:52 ±1:50 minutes/ Placebo 5k: 24:05±2:04 minutes). These data showed no significant ergogenic effect on running performance as indicated by the 5k run times completed after glycogen lowering exercise.
