There is an error in the ninth sentence of the Abstract. The correct sentence is: A peak of 44.8 ± 5.0 ml.kg-1.min-1 (89 ± 5% ), a peak heart rate of 190 ± 13 beats.min-1 (98 ± 3% HRPEAK) and peak [La-] of 12.3 ± 2.9 mmol.L–1 was elicited by the bouts.
There are errors in the last sentence of the third paragraph of the “Physiological measurements during the simulated combat” section of the Methods [1]. The correct sentence is: Then, HR intensity was classified into five zones: A (95%-100%HRPEAK), B (90–94% HRPEAK), C (85–89%HRPEAK), D (84–80% HRPEAK), E (<80%HRPEAK).
In Table 2, the value in the Total Comp column and Number of exchanges line should be 31–41. There is an error in Table 2 caption for Two-way repeated-measures ANOVA outcome. The correct sentence is: † Denotes significant difference for condition factor (Competition match and Combat simulation). Please see the corrected Table 2 here.
