Unstandardized coefficients of the regression equation and relevant statistics (standard error, -test results in terms of and value, 95% confidence interval). Constant: constant parameter; : upper arms peak power output; : coefficient of variation of the bilateral symmetry index; : coefficient of variation of the push cycle duration; : functional classification score.
