Introduction: The ankle is among the joints that most subject to injury during a practice of sports activities. However, there is still a gap on the importance of elastic taping in ankle stability. Objective: Analyze the immediate effect of the elastic taping in the recruitment pattern of the ankle muscles, in the kinematics and performance during functional activities in young adults healthy and active. Material and methods: Participated in this study, 21 volunteers, aged 27,09 ± 5,83 years, of both sexes, practitioners of Crossfit. The collection has occurred in two days with an interval of 48 hours. On the first day were carried out: anamnesis, orthopedic tests, the familiarisation with the test Star Excursion Balance Test (SEBT) and the Multiple hop Test (MHT) and three maximum voluntary isometric contraction (MVIC) of the tibialis anterior and gastrocnemius medialis. After the familiarization has occurred in the data collection electromyographic, kinematic, and performance in the tests, SEBT and MHT. On the second day, was carried out familiarisation of the gestures: the vertical jump and side cutting, where they were subsequently collected signals electromyography (SEMG) and kinematic data. It was evaluated the performance only in MHT and SEBT.All tests on both days were conducted under the conditions with and without elastic taping randomly defined by lottery. The processing of electromyographic signal and kinematic, occurred by routines specific to Matlab. The normalization of the SEMGs occurred by means of the MVIC. For kinematics, the accelerometer was positioned between the third metatarsal and lateral cuneiforme, considering the data of the axes: transverse (X) and horizontal (Z). For the comparisons were used in the test: ANOVA one-way repeated measures. The level of significance was set at p <0,05. Results: Elastic taping increase 120,8% of the peak activation of the gastrocnemius medialis during site cutting (p =0.001) and also an increase of 19.5% from the mean activation of the gastrocnemius medialis (p = 0.006) in the test of single limb hopping course. For performance, in the directions anteromedial e posteromedial in SEBT, there was an increase in the distance reached 3.8% and 5.6% (p= 0.001 and p=0.005), respectively, associated with the use of the elastic taping. In tests, cross six meter hop for time and single limb hopping course, there was a reduction in run-time, 5.7% and 7.1% (p=0.018 and p=0.009), respectively, associated with the use of the elastic taping. Conclusion: According our findings, the elastic taping has limitations as a therapeutic resource for preventive and rehabilitation, however it can be beneficial to performance in functional activities.
