Very interesting article.
A few years ago I did wonder if sport science considered this as I had started having issues with hypermobility and my cycles and so wondered if science considered these effects on athletes. And if I could glean any self help from the research! There wasn't much I could see at all.
Clearly biology does matter hugely.
I also wonder if any contraception levels the hormones out for athletes and so improves the ups and downs?
