A swim analysis is a game-changer for triathletes looking to optimize their performance in the water. Since swimming is the first and often most challenging leg of a triathlon, it’s crucial for athletes to swim efficiently, conserve energy, and minimize drag.

Swimming, while low-impact compared to running or cycling, still poses a risk of injury, especially if your form isn’t optimal. Shoulder injuries, in particular, are common among swimmers due to improper stroke mechanics or overuse. A swim analysis helps identify the root causes of such injuries, allowing athletes to make corrective adjustments to avoid strain on the shoulders, neck, and lower back. By improving body mechanics and flexibility through the analysis, triathletes can reduce the risk of injury and ensure that they can train and race at their best.

The Center for Physical Rehabilitation’s Video Swim Analysis program utilizes above-water and under-water HD video to analyze all aspects of your swim stroke. The highly-trained staff applies biomechanical principles to improve stroke efficiency and identify problem areas that may be contributing to injury or impeding performance.

What can I expect? CPR will record video footage of your swim stroke in the pool. Then, your physical therapist will evaluate all components of your swim performance: breathing, body position, rhythm and timing, catch and recovery of arms, and kick and propulsion. CPR utilizes Dartfish Software to analyze your video footage. Finally, you will receive individualized drills and a home exercise program designed to reduce the risk of injury and improve performance.

Who would benefit from swim analysis?

  • Swimmers with pain or discomfort during or after swimming.
  • Swimmers or triathletes who are looking to improve their form and reduce their risk of injury.
  • Swimmers or triathletes who want to optimize their performance and their stroke efficiency.
  • Beginners who want to learn proper form to prevent injury and improve efficiency.
