Data are presented as mean±sd, unless otherwise indicated. M: male; F: female; tLIM,75 and tLIM,85: endurance to constant work-rate test at 75% and 85%, respectively, of the peak work rate; ΔtLIM,75 and ΔtLIM,85: improvement after leg training in the 75% and 85% tests, respectively. #: CRQ-D score; ¶: ΔtLIM,75 divided by the sd of the baseline 75% test; +: ΔtLIM,85 divided by the sd of the baseline 85% test.
