Data are presented as the mean (SD).
Significant difference between groups (^ap<0.01), significant difference from baseline values (^bp<0.01), significant difference from the values obtained above (^cp<0.01).
E, energy consumption; ME, mechanical efficiency; ΔME, changes in mechanical efficiency; VO₂, oxygen consumption.
