In this episode:

Skeletal muscles are made up of fast twitch and slow twitch fibers each of which has differing properties. The amount of each fiber in muscle varies from person to person and while it is possible to determine this makeup, it is not so easy. The architecture of muscle in each individual is important in determining how a person can perform in different types of sports and also, how each will respond to training. Should people try to determine what their muscle typology is and adapt their training to it? We discuss in the Medical Mailbag. Kennon Heard is an emergency physician and endurance athlete who collapsed in cardiac arrest after a family fun run in May. He discusses his experience and how he is moving forward as well as how the rest of us should think about this experience in context of our own endurance pursuits as we age.
