Intraclass correlation coefficients (95% CI) between 1-min STS tests were 0.93 (0.83\u20130.97) for learning effect and 0.99 (0.97\u20131.00) for reliability. Standardised response means (95% CI) were 0.87 (0.58\u20131.16) and 0.91 (0.78\u20131.07). The estimated minimal important difference was three repetitions.
