Background: Research has shown that lower functional Hamstring-to-Quadriceps (Hecc:Qcon) increases the risk of hamstring and knee related injuries. Long-term methods such as plyometric training can increase hamstring strength. However, short-term measures are needed for immediate improvements. Kinesiotape (KT) can provide that option, as research has shown its effects on muscle strength. Aim: To investigate effects of KT on effect of Hecc:Qcon ratio and on functional muscle performance. Methods: 11 female soccer players underwent 1 pre-test and 2 post test, 2 hours and 48 hours after KT application on their non-dominant leg, in a within-subject repeated measures study design. They had to be free from injuries in the past 6 months and have a Hecc:Qcon ratio at 180°/s less than 0.96 on the non-dominant leg. 4 dependent variables were measured, Hecc:Qcon ratio at 180°/s and 240°/s, the maximum distance for the single-leg triple hop jump (THJ) and the maximum height for the double-leg countermovement jump. Results: Significance was only observed in the Hecc:Qcon ratio at 240°/s, with an initial increase in the leg with KT and a drop in the leg without KT (p=0.010). It decreased further in the leg without KT after 48 hours. Conclusion: It may be possible that KT assists in acute recovery, allowing continued optimal performance. It also helps with recovery after eccentric workload, reducing the effects of delayed onset muscle soreness. KT seems to be able stimulate the muscles and increase activity, resulting in slight increase in performance. Keywords: Kinesiotape, Hamstring-to-quadriceps ratio, strength, recovery
