PSEUDOEPHEDRINE IMPROVES ENDURANCE RUNNING PERFORMANCE
Hodges, K., Hancock, S., Currell, K., & Jeukendrup, A. (2005). Pseudoephedrine enhances 1500 m running performance. Medicine and Science in Sports and Exercise, 37(5), Supplement abstract 230.
Males (N = 7) completed two 1500-m time trials, one with placebo (2.5 mg/kg maltodextrins) and the other with pseudoephedrine (2.5 mg/kg). Trials were seven days apart and performed on a standard track. Ss fasted before and had a standardized breakfast on a time trial day.
Running time was reduced significantly (~2.1%) with pseudoephedrine. There were no changes in blood parameters, suggesting a central effect rather than a metabolic effect.
Implication. Pseudoephedrine improved running performance.
