The purpose of this study is to investigate the effects of muscle fatigue in the scapular kinematics of overhead athletes with and without using a kinesio taping technique for facilitating lower trapezius function. The hypothesis is that the taping technique could compensate for the negative effects caused by muscle fatigue in the scapular kinematics of healthy overhead athletes.
Muscle fatigue is a potential cause of shoulder injuries in overhead athletes. Considering the important role of lower trapezius for functional scapular stability, it is suggested that a kinesio taping technique for facilitating its function could compensate for the negative effects of muscle fatigue on scapular kinematics. This is a randomized crossover study and all included athletes will be evaluated in three sessions, with a period of seven days between them: Control (fatigue protocol, without taping), Kinesio Taping (fatigue protocol with elastic taping applied with tension) and Sham (fatigue protocol with taping applied without tension). During each session, tridimensional kinematics of scapula and humerus and electromyography of serratus anterior and trapezius (upper and lower portions) muscles of dominant shoulder will be evaluated, during scaption and throwing movements, immediately before and immediately after the fatigue protocol.The changes in scapular movements (before versus after the fatigue protocol) will be compared among the sessions.
1,860 studies on the registry are indexed under Fatigue; 376 are open to participants now.
This study's planned enrollment of 20 is below the median of 54 across 1,440 interventional studies indexed under Fatigue.

Exclusion criteria:
In this session, the athletes will be evaluated before and after the fatigue protocol, without any taping application.
Other: Fatigue protocol
A kinesio taping technique for facilitating lower trapezius muscle function will be applied just before fatigue protocol and removed after in the end of the evaluation session.
Other: Elastic taping applied with tension · Other: Fatigue protocol
A similar technique, using the same tape, will be applied but without any tension (tension is considered to be the therapeutic effect). The tape will be applied just before the fatigue protocol and removed in the end of the session.
Other: Elastic taping applied without tension · Other: Fatigue protocol
Changes in scapular internal/external rotations, upward/downward rotations and anterior/posterior tilt movements
Scapular 3D kinematics will be measured during arm elevation and throwing movements, in two moments (an average of 3 minutes before and an average of 3 minutes after the fatigue protocol) in each one of the 3 sessions. The evaluation session will have and interval of 7 days between them, and in each one the athletes will perform the fatigue protocol using either a kinesio taping application, or a sham application or without using any taping, in random order. The changes in each session (before and after fatigue) will be compared among the sessions (without taping, with kinesio taping application and sham application).
Time frame: An average of 3 minutes before and an average of 3 minutes after the fatigue protocol, in each of the 3 evaluation sessions.
Changes in the median frequency of electromyographic signal from upper and lower trapezius and serratus anterior muscles.
Electromyographic median frequency will be measured from upper and lower trapezius and serratus anterior muscles in order to determine muscle fatigue development and if the changes depending on the intervention used. These assessments will be performed in two moments (an average of 3 minutes before and an average of 3 minutes after the fatigue protocol) in each one of the 3 sessions(with an interval of 7 days between them). In each session the athletes will perform the fatigue protocol using either a kinesio taping application, or a sham application or without using any taping, in random order.The changes in each session (before and after fatigue) will be compared among the sessions (without taping, with kinesio taping application and sham).
Time frame: An average of 3 minutes before and an average of 3 minutes after the fatigue protocol, in each of the 3 evaluation sessions.
