Abstract

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.
