Table 2.

Mean and standard deviation of the bilateral coordination measured by phase coordinative index (PCI), accuracy and variability during running in four conditions: free and Nordic running in regular terrain (FR and NR), and free and Nordic running in irregular terrain (FI and NI)

Variable (%)	FR	NR	FI	NI	Mode	Terrain	Mode*Terrain
PCI	4.42 (0.37)	4.77 (0.37)	3.62 (0.40)	4.44 (0.40)	0.10	0.07	0.18
Accuracy	1.35 (0.21)	1.46 (0.21)	0.88 (0.23)	1.17 (0.23)	0.30	0.09	0.39
Variability	3.07 (0.23)	3.31 (0.23)	2.74 (0.25)	3.27 (0.25)	0.11	0.34	0.17

The p values are presented for the comparisons between conditions for the factor mode of running (free and Nordic running), terrain (regular and irregular), and their interaction (mode*terrain). The significance level used was α = 0.05
