“PCC” refers to Pearson’s correlation coefficient, “Sig.” refers to significance, “ICC” refers to intraclass correlation, “RPIn v PPIn” refers to comparing researcher perception of initial tension in a stretch with participant perception of initial sensation of stretch, “RPMax v PPMax” refers to comparing researcher perception of maximum tension in a stretch with participant perception of maximum tolerable stretch. Intraclass correlation coefficients are for absolute agreement using average measures and a two-way random effects model. Significance considered at p ≤ 0.05.
