The Effect of Variant Dosages of Amphetamine Upon Endurance.
Williams, Melvin H.; Thompson, John
The purpose of this study was to provide basic information concerning the acute effects of a small, moderate, and large dose of d-amphetamine sulfate upon muscular endurance; a secondary purpose involved the effect upon resting (R), and submaximal, and maximal (MAX) heart rate (HR). Twelve male university students underwent four separate trials of a progressive work task on an electric bicycle ergometer. Prior to each trial the subject consumed either a placebo (0 mg), small (5 mg), moderate (10 mg), or large (15 mg) dose of d-amphetamine sulfate per 70 kg body weight. A repeated measures ANOVA revealed significant F ratios (P.05) for the RHR and MAX HR. The Neuman Keuls analysis indicated the RHR for the moderate dose was higher than the placebo condition, while all three amphetamine doses elicited a higher maximal heart rate than the placebo. It was concluded that variant dosages of d-amphetamine sulfate do not influence maximal endurance capacity or the heart rate during submaximal exercise, while the effect exerted upon RHR and MAX HR may have been due to chance occurrence.
