Track and Field was my life for about 15 years:
In BB we train differently, so the tendon and joint problems are more relevant with Winnie.
For Sprinters, Winny is king, or it was when I left. But they train way differently than BBers; sprints, practice block starts, stretch, do lateral training...basically, whole body movements. They rarely handle maximal loads for singles or doubles in they gym and never do single joint exercises (leg extensions for ex.) unless they're rehabbing something. Plus, most have a lifetime of sprinting, so they're tendons have strengthened in response to training since jr. high.
Throwers: Water based test Suspension (mid-to-high doses), Drol, Var.
At one time they were using Epi-Testosterone injections when the test was based on a ratio of Test/Epi-Test.
Sprints: Winny, GH in the offeseason or whenever they can't be located easily by the IOC.
Jumpers: Winny and GH. These guys do have problems with joints, generally and from drugs. Especially Triple Jumpers. BRUTAL on the knees. But elite triple and long jumpers have some of the best strength to weight ratios I've ever seen. (170-180lb guy cleaning 385). Ridiculous strength.
Distance Runners: EPO or just strait blood-doping.
And whatever the Jamaican team is running...obviously new and undetectable.
Useless Trivia: I dunno if it's still the case, but last I was involved, the best vertical leap ever tested at the Olympic Training Center in Colo. Springs (straight up jumping) belonged to Randy Barnes. 300+lb World record holder in the Shot-put.
Think about that: Of ALL the athletes thru there, basketball players, high-jumpers, pole vaulters, boxers...it was a Shot-putter. Amazingly strong dudes.
