Table 1. Rate of perceived exertion, errors during the Stroop test, and average heart rate during the different test sessions and experimental series.

	MRGlass	Control

Post#3	2.83 ± 0.35	2.08 ± 0.35
	Number of errors during the Stroop test
Baseline	0.91 ± 0.35	0.72 ± 0.35
Post#1	0.91 ± 0.29	1.18 ± 0.29
Post#2	0.82 ± 0.28	0.82 ± 0.28
Post#3	1.27 ± 0.37	1.09 ± 0.37
	Heart rate during tests
Baseline	83.0 ± 2.9	83.4 ± 2.9
Post#1	82.4 ± 2.2	83.6 ± 2.2
Post#2	80.4 ± 2.5	81.1 ± 2.5
Post#3	78.2 ± 2.6	83.6 ± 2.6
	Heart rate during experimental series
Series#1*	81.9 ± 2.5	85.6 ± 2.5
Series#2	78.8 ± 2.6	82.7 ± 2.6
Series#3	78.1 ± 2.5	81.9 ± 2.5

Notes:

Values are means ± standard deviation. MRGlass: condition with mixed reality glasses. A significant time effect was only observed for heart rate during experimental series with significantly greater values during the first series as compared to the two others.
