The purpose of this study was to investigate the effects of four different warm-up conditions on vertical jump performance. The warm-ups included a static stretching routine, dynamic medicine ball routine, mini-band routine, and a 5-minute jog, which was the control. The subjects were 23 NCAA Division 1 women’s soccer players from North Dakota State University who performed three vertical jumps on an Advanced Medical Technology Inc. (AMTI) Force Plate after each of the four warm-up routines. The subjects were randomized into four groups for the study and rotated between the four warm-up routines, completing one routine each day in a random order. The results of the one-way repeated measures analysis of variance showed statistical significance (F=7.87, p=.007). Follow-up pairwise comparisons were done; the only statistically significant result was between the static stretching condition and the control/jog (t=-5.15, p<0.001).
