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.

Outcome Measures

Primary Outcomes (7)

• Intraclass Correlation Coefficient (ICC) for ASH Test

  Assessment of between-day reliability of the ASH test using intraclass correlation coefficients (ICC) for shoulder extension at three adduction angles (180º, 135º, 90º).

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

• Intraclass Correlation Coefficient (ICC) for IASH Test

  Assessment of between-day reliability of the IASH test using intraclass correlation coefficients (ICC) for shoulder flexion at three adduction angles (180º, 135º, 90º).

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

• Coefficient of Variation (CV) for ASH and IASH Tests

  Analysis of the coefficient of variation (CV) to evaluate data dispersion and consistency for both ASH and IASH tests.

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

• Minimum Detectable Change (MDC) for ASH and IASH Tests

  Calculation of the minimum detectable change (MDC) to identify the smallest significant change in performance beyond measurement error for both ASH and IASH tests.

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

• Force Ratios Between ASH and IASH Tests

  Evaluation of the agonist-antagonist strength ratios between ASH (extension) and IASH (flexion) tests across three adduction angles (180º, 135º, 90º).

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

• Comparison of Shoulder Strength Between Preferred and Non-Preferred Breathing Sides

  Analysis of differences in isometric shoulder strength between the preferred and non-preferred breathing sides in ASH and IASH tests across three adduction angles.

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

• Evaluation of Test Fatigue and Its Impact on Reliability

  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.

  Measured at two time points: baseline (Day 0) and follow-up (Day 2).

Study Arms (1)

Validation of ASH and IASH Tests in Swimmers

OTHER

Participants perform the Athletic Shoulder (ASH) test and the Inverse Athletic Shoulder (IASH) test to assess isometric shoulder strength at different adduction angles (180º, 135º, 90º) over two sessions. Data is collected to evaluate the reliability and validity of these tests for swimmers.

Procedure: Athletic Shoulder (ASH) and Inverse Athletic Shoulder (IASH) Tests

Interventions

Athletic Shoulder (ASH) and Inverse Athletic Shoulder (IASH) Tests PROCEDURE

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.
