"Alcohol and the Athlete." Sports Medicine. 29(5):295-300, 2000. O'Brien, Conor P. 1; Lyons, Frank 2
I could only get access to the Abstract, but a couple of things to be aware of:
"It is suggested that alcohol related problems may be more prevalent in the athletic population due to their risk taking mentality
"Alcohol consumption also appears to have a causative effect in sports related injury, with an injury incidence of 54.8% in drinkers compared with 23.5% in nondrinkers (p < 0.005). This may be due in part to the hangover effect of alcohol consumption, which has been shown to reduce athletic performance by 11.4%."
