T3/T4 and Endurance Athletes
I was just wondering if there was a reason that a lot (or seems like a lot) of endurance athletes us thyroid hormone. Adam Goucher, Galen Rupp, Floyd Landis, and a couple of other big names have stated publicly that they are on thyroid medications. I was wondering if endurance athletes have an increased likelyhood of hypothyroidism due to overtraining or if there is some sort of health/performance benefit (it was also written into Tyler Hamilton's Fuentes protocol). I know that t3/T4 use could really mess up your thyroid when not needed, but I'm just wondering if there is a relatioship.
I think a couple of people on this board (Realgains) have been diagnosed and am wondering if they could shed some light on this. I tried to do a literature search on the topic, but didn't find anything.
