I’m sure many of you have heard about or read the article in the Wall Street Journal, The Exercise Equivalent of a Cheeseburger, citing how damaging long durations of cardio can be for your health. Well, it’s not far off, and here’s why;
1. Long durations of cardiovascular exercise places enormous amounts of stress on the body.
- In an earlier post, https://ryancarsia.wordpress.com/2014/01/14/how-exercise-aging-and-nutrition-are-related/, I explained how excessive exercise creates what are known as free radicals in the body, which basically destroy all of your healthy tissues. Although free radicals are being created all the time, they are excited through long bouts of cardiovascular exercise. This is one of the many reasons why individuals who run marathons have little muscle tone and leanness, and why they seem to appear much older than they actually are.
- During this excessive stress, your body stimulates the release of a hormone called cortisol, which also damages the healthy tissues in your body. Note: this response is limited when you ingest a protein shake shortly after a workout. It is not optional, it’s MANDATORY to protect your body and see the results you want. It also surpresses the release of a hormone called T3 from the thyroid gland to allow your body to burn fat. As I have stressed before (no pun intended) in earlier posts, stress is the #1 inhibitor of fat loss!
2. Long durations of cardio also teach your body how to preserve energy
- When you are placing your body under enormous amounts of stress, it needs energy from nutrients to fuel the exercise. Doing long bouts on intense cardiovascular exercise teaches your body how to store fat so that it can be used for other biological processes in your body.
3. This added stress also places large amount of stress on your bodies tendons, ligaments, joints, and even your HEART
- All that pounding into the ground of countless repetitions your body experiences is detrimental to the body. I can’t tell you how many “runners” have come to me complaining about joint pain, tendonitis or sprains. The free radicals and cortisol your body produces in response to this type of exercise will tear your body down, and cortisol has been associated with cancer, heart disease, and visceral belly fat!
- People may argue the added health benefits from long durations of cardio, but did you know that cardiologists have been using interval training as a more popular method for cardiac rehab? Interval training is far superior to long durations of cardiovascular training because of the heart rate manipulation that allows subjects to improve heart rate function, build lean muscle to boost metabolism, burn fat, and reduce the amount of stress placed on the body because of the decreased duration.
