Sažetak
We aimed to examine the reliability and validity of the peak power output test on a Concept II rowing ergometer and to establish the “optimal resistance” at which this peak power output was observed in 87 participants with varying levels of physical activity and rowing expertise (physically inactive students, physically active students, and trained rowers). The participants preformed countermovement jump (CMJ) test on a force plate, followed by 3 maximal-effort rowing trials using the lowest, medium and the highest adjustable resistance settings (i.e., “1”, “5” and “10” on the resistance control dial on the ergometer) in randomized order. The test proved to be reliable (coefficients of variation: 2.6- 4.5% ; intra-class correlation coefficients: 0.87-0.98). The correlation coefficients between CMJ peak power and rowing peak power (both in W•kg-1) were fairly consistent across all three groups of participants and resistance levels, ranging between r = 0.70 and r = 0.78. Finally, the highest power output was observed at the highest resistance setting in two non- athletic groups, while rowers produced the highest power output at the moderate resistance setting. We conclude that the power output test on a Concept II rowing ergometer may serve as a reliable and valid tool for assessing whole- body peak power output in untrained individuals and rowing athletes.
