Reliable lower limb musculoskeletal profiling using easily operated,
Test og screening af hoppe ydeevne og bevægelseskontrol bliver ofte udført på sportsudøvere eksempelvis som før-sæson testning/screening. Pålideligheden af disse testresultater har tidligere været tvivlsom, og formålet med dette studie har været at undersøge, om let betjent, bærbart og omkostningseffektivt udstyr, såsom en kontakt måtte og to-dimensionelt video analyse udstyr, er test-retest reliabelt. Konklusionen af studiet tyder på det, selv om det er et lille antal forsøgspersoner, - men døm selv. Her er det engelske abstract og en henvisning til hele artiklen, hvis du er yderligere interesseret.

Objectives:
Jumping performance and movement-based screening tests are commonly performed on athletes pre-season. Little is known regarding the test-retest reliability of performance tests and associated movement patterns using easily operated, portable and cost effective equipment. The purpose of this study was to establish the test-retest reliability of performance and video-derived movement characteristics of six screening tests measured simultaneously using a contact mat and two-dimensional video analysis.
Methods:
Twenty-four subjects (17 male/7 female) were tested on three occasions 5–12 days apart to establish test-retest reliability of the measurement tools used. The tests used were anterior step-up, double and single-leg countermovement jumps, double and single-leg reactive (drop) jumps, and singleleg side springs.
Results:
Measures of performance demonstrated less variability (mean-typical error expressed as a coefficient of variation, CV 2.8–4.3%) and higher reliability (intraclass correlation coefficients, ICC 0.98– 0.99) for floor-based tests (preceding values) than drop tests (CV 10.3–13.2%, ICC 0.83–0.85). All videoderived movement characteristics demonstrated low variability (CV 3.2–4.8%), but lower rank order repeatability (ICC 0.43–0.79).
Conclusion:
The findings suggest that screening tests performed from the floor and measured simultaneously using a contact mat and two-dimensional movement analysis are reliable, and trialling these tests for the pre-season screening of athletes is supported.
