Brief summary
To validate both the Athletic Shoulder (ASH) test, conducted on rugby players, and its inverse, the Inverse Athletic Shoulder (IASH) test, for swimmers. This involves assessing the strength relationship between shoulder flexion and extension at three different adduction angles (180º, 135º, 90º) to identify potential injuries associated with these imbalances.
Interventions
PROCEDUREAthletic Shoulder (ASH) and Inverse Athletic Shoulder (IASH) Tests
Participants perform the Athletic Shoulder (ASH) test and Inverse Athletic Shoulder (IASH) test to measure maximal isometric shoulder strength in three positions (180º, 135º, 90º) during two separate sessions. Data is used to assess test reliability and validity for high-performance swimmers.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intraclass Correlation Coefficient (ICC) for ASH Test | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Assessment of between-day reliability of the ASH test using intraclass correlation coefficients (ICC) for shoulder extension at three adduction angles (180º, 135º, 90º). |
| Intraclass Correlation Coefficient (ICC) for IASH Test | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Assessment of between-day reliability of the IASH test using intraclass correlation coefficients (ICC) for shoulder flexion at three adduction angles (180º, 135º, 90º). |
| Coefficient of Variation (CV) for ASH and IASH Tests | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Analysis of the coefficient of variation (CV) to evaluate data dispersion and consistency for both ASH and IASH tests. |
| Minimum Detectable Change (MDC) for ASH and IASH Tests | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Calculation of the minimum detectable change (MDC) to identify the smallest significant change in performance beyond measurement error for both ASH and IASH tests. |
| Force Ratios Between ASH and IASH Tests | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Evaluation of the agonist-antagonist strength ratios between ASH (extension) and IASH (flexion) tests across three adduction angles (180º, 135º, 90º). |
| Comparison of Shoulder Strength Between Preferred and Non-Preferred Breathing Sides | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Analysis of differences in isometric shoulder strength between the preferred and non-preferred breathing sides in ASH and IASH tests across three adduction angles. |
| Evaluation of Test Fatigue and Its Impact on Reliability | Measured at two time points: baseline (Day 0) and follow-up (Day 2). | Assessment of fatigue effects during ASH and IASH tests, considering the 20-second rest period and total number of efforts (36 per participant), and their potential impact on test reliability and strength measurements. |
