Brief summary
The objective of the study is the validate and to assess the reliability of a modified version of the Athetic Shoulder Test. The activity of peri-scapular muscles during the realization of the test will be assessed too.
Detailed description
The study will be divided into two sessions. A time of 7-10 days will be provided between the two sessions of tests to limit the influence of sport and training on the results. Session 1: * Warm-up * Realization of the Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior) * Realization of the modified Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior) Session 2: * Warm-up * Realization of the Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior) * Realization of the modified Athletic Shoulder Test (with EMG captors on upper trapezius, lower trapezius and serratus anterior)
Interventions
The participants will have to perform both tests two times, with a 7-10 days rest period between the two sessions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Strength of anteflexors in I position | Change from baseline to 10 days | The strength developped in the I position will be assessed with a force plateform and a handheld dynamometer |
| Strength of anteflexors in Y position | Change from baseline to 10 days | The strength developped in the Y position will be assessed with a force plateform and a handheld dynamometer |
| Strength of anteflexors in T position | Change from baseline to 10 days | The strength developped in T position will be assessed with a force plateform and a handheld dynamometer |
| EMG activity of upper trapezius | during the first session | EMG activity of upper trapezius will be measured with surface electrodes (Delsys Trigno) |
| EMG activity of lower trapezius | during the first session | EMG activity of lower trapezius will be measured with surface electrodes (Delsys Trigno) |
| EMG activity of serratus anterior | during the first session | EMG activity of serratus anterior will be measured with surface electrodes (Delsys Trigno) |
