- Description: Objectives: To compare the change in supraspinatus tendon thickness (STT) following a high volume (HV) and high intensity (HI) swimming practice in shoulders of elite swimmers. Design: Cohort Study. Setting: Non-clinical, state swim team training facility. Participants: A convenience sample of eight non-injured state and national level swimmers from a regional swim team were recruited for this study. Main outcome measures: Ultrasound measures of STT were collected in response to the two swimming practice sessions. Measures were taken prior to each swim practice; immediately after practice; 6-hours post practice and 24-hours post practice. Results: A significant increase in STT resulted from both the HI and HV (p < 0.05) practice immediately post practice. For the HI practice, the STT remained significantly thicker than pre-practice measures at the 6-hour post practice test (p < 0.05) however no longer significant 24-hours post practice. The difference in the change in STT between the HI and HV practice was significantly different immediately post practice and 6-hours post practice (p < 0.05) however no longer significant 24-hour post practice. Conclusion: Ultrasound measures of STT following different swimming volumes and intensities may provide information on shoulder tendon loads. © 2020 Elsevier Ltd

- Description: Swimming is one of the top three participant sports in Australia and enjoys a high public profile. Shoulder injuries are commonly sustained by swimmers and are associated with significant morbidity as well as impaired swimming performance. Supraspinatus tendinopathy has been found to be present in a large proportion of competitive swimmers. The use of ultrasound has been found to be a reliable and valid tool in assessing supraspinatus tendon thickness changes. Primarily this thesis investigated the relationship between changes in supraspinatus tendon thickness and shoulder pain among elite Australian swimmers. The thesis investigated how swimming practice load and intensity resulted in supraspinatus tendon thickness changes. Furthermore, retrospective data investigates the link between training related supraspinatus tendon thickness changes and future incidence of shoulder pain. The research ascertained that swimming practice results in significantly greater increases in supraspinatus tendon thickness in swimmer’s shoulders with a history of shoulder pain. The evaluation of volume and intensity demonstrated a greater increase in thickness as a result of high intensity low volume practice compared with that of high volume low intensity practice in swimmer’s shoulders without a history of pain. While retrospective data identified a significant association between the increase in tendon thickness immediately post a swimming practice and the tendon thickness at six hours post practice and the incidence of significant interfering shoulder pain at both three and six months post testing. These findings provide an evidence base for the use of supraspinatus tendon thickness measures to assess a swimmer’s readiness to train when returning from an episode of shoulder pain. Additionally, the shoulder tendon response to varying training loads, including different intensity and volume and how this may be associated with future incidence of pain may guide coaches and clinical staff in the planning of training programs and training periodisation to manage shoulder pain incidence
