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

Table 1

Treadmill-based incremental workload test for manual wheelchair users. The slope and speed of the treadmill were incrementally adjusted at each stage of the test until participants were unable to match the treadmill’s speed.
