I just finished a book entitled
The Haywire Heart - How Too much exercise can kill you, and what you can do to protect your heart.
It's written by athlete cardiologists and Lennard Zinn, who many may know from his books and technical articles on cycling.
It has lots of actionable information for the masters athlete.
If you're a cyclist with concerns about your cardio health, I highly recommend getting a copy. It's available from
velopress.
Here's a
review of the book from cardiologist and athlete Larry Creswell, MD.
