Reliable lower limb musculoskeletal profiling using easily operated, portable equipment.

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