I've been looking at Lia Thomas conversations on Twitter (I know, I shouldn't) and saw this:
'the stat of her placing in the 400s was when she was competing in the men’s division while she was transitioning. before her transition she was placing first in men’s leagues. she’s just a good swimmer'
I instinctively think this is bunkum, but I looked on Wikipedia (yes, I know, not exactly peer-reviewed etc etc but I'm not a scientist and can't read hard data).
It looks as if Thomas's performance/ranking has suffered from the transition process:
'during her freshman year [Thomas] recorded a time of 8 minutes and 57.55 seconds in the 1,000-yard freestyle that ranked as the sixth-fastest national men's time, as well as 500-yard freestyle and 1,650-yard freestyle times ranked within the national top 100… During the 2018–2019 season, Thomas recorded the top university men's team times in the 500 free, 1000 free, and 1650 free.
'She began transitioning using hormone replacement therapy in May 2019… Her time for the 500 freestyle is over 15 seconds slower than her personal bests before medically transitioning. Thomas's event progression peaked in 2019 for distance swimming, with a drop in times during the 2021–22 season.'
BUT then it says 'Her event progression for sprint swimming reflected a dip at the start of 2021–22 season before returning to near-lifetime bests in the 100 free and a lifetime personal best in the 50 free in 2021.'
So does this mean Thomas had a dip in performance while actually transitioning, but now is getting back to previous – male – form?
