  • All measures are reported as mean (SD). Significant main effect (p<0.05) between engagement techniques (#) and pairwise comparisons are reported by the following convention: 1=different from CTPE; 2=different from CTS; 3=different from PreBind.

  • CTPE, crouch-touch-pause-engage; CTS, crouch-touch-set.
