تأثیر دو نوع متفاوت تیپ بر نیروی برشی قدامی زانو حین پرش- فرود تک‌پا در والیبالیست‌های مرد نخبه با پیچ‌خوردگی مزمن خارجی مچ پا

Background: Today, different types of tapes used for prevention and treatment of chronic inversion ankle sprain. The purpose of current study was to investigate the effect of two different tapes (white and Kinesio tape) on peak knee anterior shear force during landing after the jump among elite volleyball players with chronic inversion ankle sprain. Methods: In this semi- experimental study, 12 elite male volleyball players with history of chronic inversion ankle sprain with age (SD) of 22.04&plusmn;3.10 years, mass (SD) of 79.74&plusmn;4.56 kg and height (SD) of 188.75&plusmn;5.85 cm were selected. Jump-landing task was performed in three conditions: barefoot, ankle white taping and ankle Kinesio taping. A force plate system was used to record the ground reaction forces. Posterior component of reaction forces in sagittal plane considered as knee anterior shear force and normalized to body weight. For analysis the data, ANOVA repeated measures method was used in SPSS v. 20 (p<0.05). Results: There was no significant difference between three conditions of white tape, Kinesio tape and barefoot landing in knee anterior shear force (p>0.05, for all conditions). Conclusion: Intervention of two types of tape could not lead to reduction in risk of anterior cruciate ligament injury in single limb landing. Thus, two studding tape could not recommended as safe intervention in ACL injury prevention during landing
