A negative value indicates a decrease in pre- to posttest changes. BW, body weight; CUT, preplanned cutting; DLJ, double-leg jump; HT, height; SEM, standard error of the mean; SLJ, single-leg jump; UACUT, unanticipated cutting.
Statistically significant effect (P < .05, repeated-measures analysis of variance).
