Cardiovascular Health

Greek researchers found that marathon runners have increased stiffness of the large arteries, which increases the probability of hardened arteries, high blood pressure and heart attacks.  The study compared runners on a traditional marathon training program with recreational exercisers.

Where do we fit?  CrossFit is its own category.  We train for marathons doing shorter, intense endurance workouts combined with regular CrossFit regimens.  By training at higher intensity for shorter intervals we see endurance gains without the accompanying injuries.   "Regular long-term endurance training is generally beneficial for heart health, but it seems that the cardiovascular system is like a sports car engine. If you do not use it, it will decay, but if you run it too fast for too long, you might burn it out," says Dr. Despina Kardara of Athens Medical School  

This does not mean you should stop exercising.  It means you should stop the Long, Slow Distance most marathon training regimens prescribe.  Replace it with moderate distance at higher intensity.  Your heart will thank you.

 Happy St Patrick's Day!
