  1. ND: non-dominant hand side; D: dominant hand side.
  2. Handgrip strength is expressed in N; all other muscle function are expressed in N.m. Height is expressed in cm. SD is the residual standard deviation of the regression. The equation takes the form: log(MVIC) = a + b.height, a and b being the regression coefficients given in the table. Knowing the height of the subject, this equation can be easily used by computing the theoretical strength as: MVIC = exp(a + b.height).
