Abstract Summary
Rowing involves continuous repetitive motion and high intensity loading on the glenohumeral (GH) joint. These factors significantly influence performance and injury propagation. This is the first study to specifically explore three-dimensional shoulder biomechanics with motion capture and musculoskeletal modelling to assess scapular and humeral movement during rowing. At key points during the stroke we found high GH joint reaction forces, stability ratios and decentralization of humeral head, which may have implications for shoulder pathologies such as impingement or instability.
