Changes to Biceps and Supraspinatus Tendons in Response to a Progressive Maximal Treadmill-Based Propulsion Aerobic Fitness Test in Manual Wheelchair Users: A Quantitative Musculoskeletal Ultrasound Study.

摘要: Objective To investigate if the completion of a recently developed treadmill-based wheelchair propulsion maximal progressive workload incremental test alters integrity long head biceps and supraspinatus tendons using musculoskeletal ultrasound imaging biomarkers. Method Fifteen manual users completed test. Ultrasound images were recorded before, immediately after, 48 hours after standardized protocol. Geometric, composition, texture-related biomarkers characterized tendon integrity. Results Participants propelled during 10.2 ± 2.9 minutes with majority (N = 13/15) having reached at least eighth stage (speed 0.8 m/s; slope 3.6°). All characterizing integrity, measured in longitudinal transversal planes for both tendons, similar (p 0.063 to 1.000) across measurement times. Conclusion The performance motorized treadmill assess aerobic fitness produced no changes or tendons. Hence, there was evidence maladaptive response due overstimulation these
