Failure of protein to improve time trial performance when added to a sports drink

Article Abstract:

An investigation was conducted to determine whether the addition of 2% protein to a 6% carbohydrate drink would improve 80-km cycling time trial performance, as compared with a 6% carbohydrate drink and nonenergetic sweetened placebo. The results indicate that when trained cyclists ingested carbohydrate during exercise at a rate considered optimal for exogenous carbohydrate oxidation, the addition of protein did not further enhance performance during a time trial task that closely simulated athletic competition.

Pseudoephedrine enhances performance in 1500-m runners

Article Abstract:

Pseudoephedrine is an over-the-counter drug to relieve nasal and sinus congestion, thus a study is aimed to investigate the effects of pseudoephedrine on 1500-m running performance. The results reveal that 2.5 mg.kg(super -1) bw pseudoephedrine ingested 90 min preexercise improves 1500-m running performance.
