I've always wondered why would footballers or tennis people dope. In games with limited aerobic requirements (both are very stop-start) and mostly skill, there seems to be little benefit. Maybe doping to assist recovery, but agin in these types of sport the tank would rarely be emptied. This is one of the main reasons why doping was so vigorous in cycling, it's such an endurance sport that it did have a pronounced effect.
Other sports that I would figure would benefit most would be track and distance runners, triathlon and ironman, rowing and maybe some of the longer swimming events. Obviously pure strength events would benefit from anabolic's, HGH & testosterone such as weightlifting, sprinting etc...
Would be interesting to understand just what some sports people would gain and where....
