Ten well-trained male cross-country skiers (age: 19 ± 1.4 y; height: 182 ± 72 cm; body mass: 76.0 ± 10.8 kg, whole body VO<sub>2Peak</sub>: 5.2 ± 1.0 L.min<sup>-1</sup>; upper body VO<sub>2Peak</sub>: 4.6 ± 1.0 L.min<sup>-1</sup>; upper body:lower body ratio: 87.2 ± 5.6%) performed four VO<sub>2Peak</sub> tests; one treadmill ski-striding test and three double poling ski-ergometer tests over five days. Test-retest reliability of the ski-ergometer protocol was determined for maximal oxygen consumption (VO<sub>2peak</sub>). The ski-ergometer test showed excellent reliability for VO<sub>2Peak </sub>(L.min<sup>-1</sup>) (coefficient of variation [CV] = 1.9%, 95% confidence limit [95% CL] [1.2, 4.7]; <em>r</em> = 1.00, [0.96, 1.00]) and UBP<sub>Peak </sub>(W) (CV = 1.4%, [0.9, 3.4]; <em>r</em> = 1.00, [0.97, 1.00]). Very strong correlations existed between the ski-ergometer and the ski-striding protocol for VO<sub>2Peak</sub> (<em>r</em> = 0.95, [0.76, 0.99]). The upper body ski-ergometer test provided valid and reliable measurements of ski-specific upper body aerobic power in well-trained male cross-country skiers.</p> ER -
