The purpose of this study was to compare the vertical jump height and peak landing vertical ground reaction forces (VGRF) produced by traditional and swing blocking in volleyball. Twenty NCAA Division II female volleyball players were recorded on a Kistler force platform performing 4 blocks (i.e. 1 traditional & 1 swing block to the right and left). Repeated measures ANOVA revealed no significant differences for vertical jumps (F=1.223, p>.05). However significant differences in landing did occur (F=4.613, p<.05). Post-hoc t-test using Bonferroni adjustments revealed significantly higher peak landing VGRF for swing blocking to the right in all cases. It was concluded that swing blocking to the right produced significantly greater peak landing VGRF than traditional blocking and swing blocking to the left. Vertical jump height was not affected by blocking style in this investigation.
