Figure 2. The 2000-m all-out rowing performance test (MPT) split times, oxygen uptake (VO₂), carbon dioxide output (VCO₂),respiratory exchange ratio (RER), heart rate (HR), stroke rate (SR) and stroke power (P) after a usual low intensity warm up (MPT_low) and an additional 25 s all-out arm crank pre-load (HIE) (MPT_high). * Significantly different from MPT_low (p < 0.05).
