The purpose of this study is analyze the immediate and late effects of the application of KT in neuromuscular performance of the quadriceps in postural balance and function of the lower limb of healthy subjects.
Sixty volunteers, females will be recruited and randomly divided into 3 groups with 20 members each: control group (CG) - 10 minutes at rest; placebo group (PG) - Kinesio Taping (KT) without application of tension in the vastus lateralis (VL), vastus (VM) and rectus femoris (RF); and Kinesio Taping group (KTG) - application of KT with tension in VL, VM and RF. All volunteers will be evaluated for their distance from the single and triple hop test, postural balance (baropodometry), the joint position sense (JPS), the knee extensor torque (concentric and eccentric assessment at 60 °/s) and electromyographic activity of the VL muscle in five distinct stages: the first before the intervention (AV1), the second immediately after (AV2) and the following three 24h (AV3), 48 (AV4) after the intervention protocol. Soon after the AV4, KT will be removed after 24 hours and take place the last review (AV5).

Muscle Performance measured through isokinetic dynamometry
Change from baseline in muscle performance at 72 hours.Immediate and Delayed Effects of Kinesio Taping in the muscle performance will be measured through isokinetic dynamometry and the variables analyzed will be peak torque normalized for body weight, mean power, total work and time to peak torque.
Time frame: baseline, one minute after the intervention protocol, 24 hours, 48 hours and 72 hours after the intervention protocol.
Balance measured through baropodometry
Change from baseline in balance at 72 hours. Immediate and Delayed Effects of Kinesio Taping in balance will be Measured by baropodometry
Time frame: baseline, one minute after the intervention protocol, 24 hours, 48 hours and 72 hours after the intervention protocol.
Lower limb function
Change from baseline in lower limb function at 72 hours. Immediate and Delayed Effects of Kinesio Taping will be measure through distance of the single and triple hop test.
Time frame: baseline, one minute after the intervention protocol, 24 hours, 48 hours and 72 hours after the intervention protocol.
Proprioception measured through joint position sense in the isokinetic dynamometer
Change from baseline in proprioception at 72 hours. Immediate and Delayed Effects of Kinesio Taping in the proprioception will be measured through joint position sense
Time frame: baseline, one minute after the intervention protocol, 24 hours, 48 hours and 72 hours after the intervention protocol.
Muscle activation measured through surface electromyography
Change from baseline in muscle activation at 72 hours. Immediate and Delayed Effects of Kinesio Taping in Muscle activation will be Measured by surface electromyography
