A bit more than the canter around that you suggested though. That is proposed, but it is noted that it is anecdotal. It is consistent with limited research cited on requirements for adaptation to firm surfaces and tighter turn radiuses though. Also, consistent with trends observed in the US where injury rates have declined on new synthetic surfaces over the first few years, presumably as horses adapt to them. Might also be part of the reason why Cambridge has much lower injury rates than the two newer synthetics.
It seems from my reading though that the report is quite clear that we have insufficient data to draw any clear conclusions about what is required for that adaptation to occur.
Horses can adjust to different surfaces by fine tuning how the tendons dampen the loading of the limb (Wilson et al., 2001). However, we currently lack data on how quickly a horse can readjust from working, or training, on one type of surface to a different surface (Bardin et al., 2021). Data from a cross-sectional survey of dressage horses indicates that horses habituate to a certain surface and may in the short-term lose the ability to respond positively to different surfaces if variety in training surfaces is not included as part of the routine training programme (Murray et al., 2010)
