A corrigendum on
Comparison of Peak Oxygen Uptake and Test-Retest Reliability of Physiological Parameters between Closed-End and Incremental Upper-Body Poling Tests
by Baumgart, J. K., Skovereng, K., and Sandbakk, Ø. (2017). Front. Physiol. 8:857. doi: 10.3389/fphys.2017.00857
In the original article, there was a mistake in Table 1 as published. The mistake concerns the peak power output values provided for the 1-min and the 3-min test. We initially based the calculations on the mean peak power output of the 1-min and the 3-min test on the values provided by the internal software of the Concept2 ski ergometer, which are cumulative averages (i.e., the first average is an average over the first 30 s, the second average is an average over the first minute, the third over one and a half minutes and so forth). However, when submitting this manuscript we recalculated the mean peak power output to reflect 30-s averages that are not cumulative and hence independent of the power output produced in the previous 30-s period.
Table 1. Power output, physiological and perceptual parameters of test day 1 and 2 for a 1-min, a 3-min and an incremental upper-body poling test in able-bodied, upper-body trained participants (means ± SD).
The corrected Table 1 appears below.
In the original article, there was an error. The mistake is in line with what is described in the above.
A correction has been made to the section Results, subsection Comparison of Tests, paragraph 1:
Based on the average values of test day 1 and 2, the incremental (45.4 ± 5.5 mL·kg−1·min−1, 196 ± 28 W) and the 3-min test (44.5 ± 5.5 mL·kg−1·min−1, 201 ± 36 W) resulted in significantly higher VO2peak and lower POpeak as compared to the 1-min test (40.4 ± 5.0 mL·kg−1·min−1, 256 ± 47 W) (all p < 0.001). Additionally, the incremental test resulted in significantly higher VO2peak (p = 0.03).
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way.
The original article has been updated.
