Table 2.

Mean and standard deviation (SD) of count output and step output for each monitor model at self-selected slow, medium and fast speeds.

	Count Output (cnts·min⁻¹)				Step Output (steps·min⁻¹)
	Output from AM1		Output from AM2		Output from AM2		Output from AM2
	Mean	SD	Mean	SD	Mean	SD	Mean	SD
Slow	902	630	888	713	56^*	30	34^*	34
Medium	3448^*	1131	3264^*	1126	110	11	109	12
Fast	6996	2669	6898	2655	135	20	135	20

AM1 refers to ActiGraph model 7164 and AM2 refers to ActiGraph model GT1M Self-paced slow speed (mean ± SD) 0.7 ± 0.22 m·s⁻¹, medium speed 1.3 ± 0.17 m·s⁻¹, fast speed 2.1 ± 0.61 m·s⁻¹.

indicates the average count output between models was significantly different at α=0.05.
