The purpose of the study was to determine the effect of non-elastic adhesive ankle taping on counter movement vertical jump ability. The use of taping techniques is widespread in order to prevent and treat ankle ligament injuries; the effect of these techniques on functional performance has only received limited study. The study undertaken examined the effect of taping and exercise on vertical jump height measured on a vertical jump test mat (Coachwise, UK) in 20 healthy uninjured male volleyball players. The effect of ankle taping was evaluated by repeated measures 1-way ANOVA. Taping was found not to alter vertical jump performance (p=0.91) despite the taping bringing about a significant reduction in range of movement (plantar flexion p=0.001; dorsi-flexion p=0.001). The restriction to movement provided by the tape was reduced significantly after a 10min running task (plantar flexion p=0.014; dorsi-flexion p=0.001), but still offered a significant reduction to range compared to the un-taped condition (plantar flexion p=0.01; dorsi-flexion p=0.01). The increased range allowed after exercise did not bring about an increase in vertical jump ability (p=0.9). The results of this study indicate that taping though restricting range of movement does not affect vertical jump performance. Furthermore, even though the effect of taping on restriction of range of movement is reduced with exercise it still offers a significant reduction to movement. Prophylactic ankle taping as used in this study, would appear to offer movement restriction without affecting function.
