What happens during a pitching biomechanics analysis?

Reflective markers are placed on the athlete while 3-D cameras capture the pitching motion. An animation and measurements of the pitcher's biomechanics are generated which allow a dynamic analysis of the pitching motion.

Before arriving at the Motion Analysis Center, athletes complete a questionnaire about their medical history and pitching habits. Upon arrival, a physical therapist performs an assessment to evaluate the athlete's muscle strength and flexibility, joint range of motion and posture.

The biomedical engineers/kinesiologist will conduct the test by placing special reflective markers specific body landmarks using small non-latex, double-sided stickers.

The athlete then warms up on a regulation mound, throwing balls at a target strike-zone. After warm-up, the athlete pitches while our special high speed 3-D cameras record the body's motion. The entire visit should take approximately 2.5 hours. However, athletes will only be pitching for about 15 to 30 minutes, including warm-up.

Preparing for your analysis

On the day of your appointment:

The athlete should not be experiencing any pain. If there has been a recent injury or pain, the athlete must be cleared by a physician to pitch.
The athlete should not pitch prior to their appointment. They should not pitch at all on the day of their appointment, as doing so can affect motion patterns and the integrity of the analysis.
Athletes need to wear or bring elastic waistband shorts, low-cut socks, gym shoes, a baseball hat, and their baseball glove to the Motion Analysis Center.
Athletes should not apply skin lotion or cream on the day of their appointment as the lubrication from lotions can make it difficult for the markers used to record motion to adhere to the skin.
