Intervention model description: The muscle strength of the right knee flexors and extensors will be verified using the isokinetic dynamometer and the muscular activation of the right knee extensors (rectus femoris muscle) will be assessed using surface electromyography. The elastic bandage will be applied over the muscular belly of the right rectus femoris muscle. Initially, all participants will be evaluated without tape, immediately receiving it without tension and, after 20 minutes of rest, they will be reassessed. All will be randomized into two groups and both will receive adhesive tape with or without tension in the application. In the eighth and last week, before the last application of the tape, everyone will be reevaluated without the tape. Then, the last application of the adhesive tape will be carried out with or without tension (according to their respective groups) and after 20 minutes of rest, everyone will be evaluated again with the last application of the tape.
Primary purpose: PREVENTION

Brief summary: It is a controlled and randomized clinical trial with the objective of verifying the acute and chronic effects (8 weeks) of elastic banding in runners. Thus, we have as hypotheses of this research: The elastic bandage indirectly influences the muscular strength to the extent that it supposedly can alter the muscular activation verified through the surface electromyography in individuals submitted to the training as the running training. The elastic bandage has clinical significance, however, it does not present statistical significance on muscle strength and activation in individuals submitted to training as running training. To confirm these hypotheses, the muscle strength of the flexors and extensors of the right knee will be checked by means of the isokinetic dynamometer and the muscular activation of the extensors of the right knee (rectus femoris muscle) will be assessed by means of surface electromyography. The elastic bandage will be applied according to a specific protocol in "I" over the muscular belly of the right femoral rectus muscle (which will be submitted to evaluations). All participants will be evaluated without applying adhesive tape and will receive the first application of the tape without tension. Then, after 20 minutes of rest, they will be reassessed with the tape. Participants will be randomized into two groups and both will receive the adhesive tape (with or without tension according to randomization). Then the evaluations will be repeated (all will be reevaluated without the tape and with the tape (with or without tension according to the protocol).

Detailed description: It is a controlled and randomized clinical trial in order to verify the acute and chronic effects (8 weeks of application) of the elastic bandage in runners. hus, we have as hypotheses of this research: The elastic bandage indirectly influences the muscular strength to the extent that it supposedly can alter the muscular activation verified through the surface electromyography in individuals submitted to the training as the running training. The elastic bandage has clinical significance, however, it does not present statistical significance on muscle strength and activation in individuals submitted to training as running training. To confirm these hypotheses, the muscle strength of the flexors and extensors of the right knee will be checked by means of the isokinetic dynamometer and the muscular activation of the extensors of the right knee (rectus femoris muscle) will be assessed by means of surface electromyography. The elastic bandage will be applied according to a specific protocol in "I" over the muscular belly of the right femoral rectus muscle (which will be submitted to evaluations). Initially all participants will be evaluated without applying adhesive tape and, in sequence, they will receive the first application of the tape (for all participants, the tape will be applied without tension) and after 20 minutes of rest, they will be reassessed with the application of the adhesive tape . After the initial assessment, participants will be randomized into two groups and both will receive adhesive tape. The FT (free tension) group will have no tension in any of its tape applications; and the WT (with tension) group will have progressive tension over 8 weeks of intervention (with reduction of the tape length over the weeks, in relation to the same size of the applied area, which generates a longitudinal tension of the tape in relation to skin of the participant). In the eighth and last week of intervention, before the last application of the tape, everyone will be evaluated again (strength and muscle activation) without the tape. Then, the last application of the tape will be performed with or without tension (according to their respective groups) and after 20 minutes of rest, the evaluation of all participants will be performed again with the last application of the tape to the rectus femoris muscle.
