  1. Presented with mean and standard deviations (SD), in degrees, standard error of the measurement (SEM), ICC(2,1) with 95% confidence interval, and number of trials needed to obtain an ICC(2,k) of at least .80. Slow (S) and fast (F) speed conditions and loaded (a), no load (b) and counterweighted (c) load conditions are presented.
