Graphical depictions of the experiments. a Participants performed repeated sit/stand cycles as fast as possible for 30 s at a time with 30 s rest intervals for 10 rounds. b Participants performed an incremental shuttle walk test involving repeated walking between two stools approximately 6 m apart (illustration modified from [20]). Walking laps between the stools continued until the participants could no longer maintain the cued pace, which slowly increased throughout the experiment. c Participants walked on a treadmill at a self-selected fast pace for 15 min
