Test Re-test Reliability of Single and Multijoint Strength Properties in Female Australian Footballers

Abstract Purpose To examine the test re-test reliability of isometric maximal voluntary contractions (MVC) hip adduction (ADD ISO ), abduction (ABD and multijoint leg extension (SQUAT ) in sub-elite female Australian footballers. Methods Data were collected from 24 footballers (age 22.6 ± 4.5 years; height 169.4 5.5 cm; body mass 66.6 8.0 kg; 4.4 years sport-specific training; 2.5 2.0 unstructured resistance training) same club on two non-consecutive days. Participants performed three MVCs ADD , ABD SQUAT . The was at 140° knee flexion with a vertical trunk position measures supine 60° flexion. Reliability assessed using paired t tests intraclass correlation coefficient (ICC) 95% confidence intervals (CI), typical error (TE), variation (CV%) CI. Results peak force (ICC .95; CV% 4.1), for left, right, sum .90–.92; 5.0–5.7), .86–.91; 6.2–6.9) deemed acceptably reliable based predetermined criteria ? .8 ? 10). Conclusion demonstrated acceptable assessment footballers, suggesting these assessments are suitable muscle strength testing monitoring adaptations to training.
