Why the study?
Do small or moderate doses of ethanol affect heart rate and oxygen consumption during exercise in healthy males?
Do small or moderate doses of ethanol affect heart rate and oxygen consumption during exercise in healthy males?
Small to moderate doses of alcohol do not significantly alter heart rate or oxygen consumption during progressive exercise in healthy males.

Small-moderate alcohol doses do not alter HR or oxygen uptake during exercise in healthy men; leaves open effects in patients or on performance.
The purpose of this study was to provide basic information on the acute effects of small and moderate doses of alcohol on heart rate and oxygen consumption before, during, and after a progressive workload. Nine male university faculty and students underwent three separate trials of a 9-min. work task consisting of 3 min. each at 500, 1,000 and 1,500 kpm. Prior to each trial, the subjects consumed either a placebo (.0cc/lb.), small (.2cc/lb.), or moderate (4cc/lb.) dose of ethanol. Although a significant F ratio was obtained for the last minute of the 1,000 kpm workload, the overall analysis by within-group t test and repeated-measures A NOV A supported the conclusion that neither a small nor moderate dose of alcohol significantly affected the heart rate or oxygen uptake during rest, exercise, or recovery.
