Key: IPA = initial peak acceleration; SD = standard deviation; n = participants; ICC = intraclass correlation coefficient; CI = confidence interval; SEM = standard error of measurement; MDC = minimal detectable change; kmph = kilometres per hour; Excel. = excellent. Note: ICC ratings are as follows: poor <0.40, fair = 0.40–0.70, good = 0.70–0.90 and excellent = >0.90 (Coppieters et al., 2002).
