Phelps and Bolt were both able to take advantage of their physical advantages, which gave them their competitive edge. I wasn't suggesting that Semenya should shorten her legs or feet. She hasn't cheated to get those elevated testosterone levels and neither did Phelps or Bolt to get theirs.
And where do you draw the line with regard to regulating testosterone levels? Do you start regulating men's as well, as some men have higher levels relative to other men and then have a competitive advantage?
But the IAAF have allowed women's world records from the 1980s to still stand, which can't possibly have been done without PEDs. Semenya even with elevated testosterone still can't get within a second of the 800m world record, which has stood since 1983 (pre out of competition drug testing). Flo Jo's 10.49 secs in the 100m is the most ridiculous time which will unlikely ever to be broken and can't possibly have been performed without PEDs.
Caster is basically being told to take something to suppress something naturally occurring to her whilst the IAAF still recognise times performed by women who took PEDs to enhance their performance as the world's best times performed by a woman. It's a stance which is irreconcilable and IMO any records pre 1988 and still standing should no longer be recognised and assumed PED enhanced.
1. no, you don't regulate mens testosterone because it's an open event. testosterone is tested for womens' events because people are defined as women based on their testosterone level. the same applies to people with only female genitalia and to people with female and male genitalia. the alternative is to just have an open (ie mens') event, and to stop having sports events for women.
2. I don't understand your argument that because IAAF were unable to accurately test for performance enhancing drugs in the 1980s, they shouldn't be allowed to test whether competitors in womens' events are women now. makes no sense to me.
