I recently participated in an event where participants carried out two 'max' attempts in different disciplines in one day (STA/DYN). The sessions were four or five hours apart which presumably is (plenty more than) sufficicent time for our gas exchange system to re-equilibrate, and I presume, for the 'dive response' to be 'reset'. However I would expect that the experienced competitors ion thast event understood intuitively that their performance in the afternoon session would be reduced as a consequance of the morning session.
By way of example, I personally pushed hard in the morning session, and found my capability in the afternon sesion reduced by 25+% when compared to PB attempt in preceding week under comp conditions at same time of day. Both attempts on the day were true maximal performances, the morning 99%, the afternoon 101%.
So this is something that is intuitively understood, but what is the mechanism?
