Activity	Biopac (GS)	Apple Watch (AW)	Polar Vantage (PV)	ANOVA (p)
Lying	62,92 ± 10,72	62,62 ± 10,59**	61,87 ± 10,68***	< .001
Sitting	71,18 ± 12,39	70,94 ± 12,40	69,95 ± 12,36	.278

*p < .05;

Significance is shown according to Bonferroni contrast tests applied to compare the differences between HR mean values from an ANOVA analysis between wearables.

**p < .01; ***p < .001. Significant difference compared to GS (Bonferroni contrast test for repeated measures). Statistical Power: π = 0.99.
