FDNS 2050 Lecture Notes - Lecture 29: Middle-Distance Running, Splanchnic, Cardiovascular Disease
Document Summary
Paradoxical sympathetic effect: release of epinephrine. Alcohol: effects on sprint and middle distance running. Dosages: ethanol to elicit bac of 0. 01,0. 05, and 0. 10. Impaired 200-meter performance, more so with higher bac. Impaired middle distance running (800 meters most adversely affected) Previously alcohol use was banned for all olympic athletes, but was removed from the banned list in 1972. Alcohol is not an essential component of a diet. However, there is no evidence of impairment to health or exercise performance when alcohol is consumed sensibly.

Heavy alcohol intake should be avoided the night before competition. Alcohol intake immediately before and during exercise does not improve and may impair performance. Heavy alcohol intake may impair post-exercise recovery. Alcohol use is prohibited in-competition for certain sports.
