What is a weighted ball velocity throwing program? Do they work, and what is the evidence of benefit? What are the risks involved and common injury patterns seen?

Host Dr. Devin McFadden, MD, is joined by Dr. Jason Zaremski, MD, to explore these topics and more on the AMSSM Sports Medcast.

Dr. Zaremski is a clinical associate professor holding a joint appointment from the Departments of Physical Medicine and Rehabilitation and the Department of Orthopaedics and Rehabilitation at the University of Florida. In addition, he is the Co-Medical Director of the Adolescent and High School Outreach Program at the University of Florida. He is a past participant in the AMSSM International Travelling Fellowship program, is a Co-Chair of the AMSSM Fellowship Committee and currently serves on the Board of Directors for the AMSSM.

In this 17 minute conversation. Dr. Zaremski addressed the following topics:

• Defining a weighted ball velocity program.
