The purpose of this study was to investigate the effects of closed basket weave ankle taping on the vertical ground reaction force and ankle movement during the contact phase before the take-off in vertical jump performance. Twelve healthy young men performed a vertical jump performance on a force plate without (CON) or with ankle taping (closed basket weave technique: CBW) of the right ankle joint. Vertical jump ability was assessed using two styles of vertical jump with no arm swing: a countermovement jump (CMJ) and squat jump (SJ). From the vertical ground reaction force (GRF), maximum jump height (Ht), vertical impulse (VI), rate of force development (RFD), maximum GRF (GRFmax) during the contact phase before the take-off in jump performance were determined. Also, movement analysis, range of motion (Δ ank) and angular velocity (Vank) of ankle joint were caliculated . Ht and RFD, Δ ank, Vank were significantly lower for CBW than CON in CMJ, but not in SJ. Conversely, VI and GRFmax were not significantly different between the groups in either jump condition. These results suggest that ankle taping impairs countermovement jump performance, due to a decreased ability to rapidly develop large force and plantar-flexion motion on the ground before the take-off.
