The purpose of this study was to investigate the effects of closed basket weave ankle taping on the vertical ground reaction force during the contact phase before the take-off in vertical jump performance. We hypothesized that ankle taping would limit the capability for explosive force generation during the contact phase before the take-off in jump performance. Twelve healthy young men (age 20.2±1.3 years, height 1.76±0.05 m, body weight 66.1±6.1 kg, mean ± SD) 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), and time-series GRF (GRFts) during the contact phase before the take-off in jump performance were determined. Ht was significantly lower for CBW (36.6±6.6 cm) than CON (38.1±6.7 cm) in CMJ, but not in SJ. RFD and GRFts at 35, 40, 45, 50, 55, 60, and 65% of total time of the contact phase in jumping performance were also significantly smaller 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 develop large force rapidly on the ground before the take-off.
