  1. *p < .05;
  2. Significance is shown according to Bonferroni contrast tests applied to compare the differences between HR mean values from an ANOVA analysis between wearables.
  3. **p < .01; ***p < .001. Significant difference compared to GS (Bonferroni contrast test for repeated measures). Statistical Power: π = 0.99.
