How to Rebuild Your Lungs

The story begins with the death of Dr. Dardik’s friend Jack Kelly (brother of Grace Kelly). He was an Olympic oarsman and the President of the U.S. Olympic Committee. One morning, he went out for his usual run … and then dropped dead of sudden heart failure.

Comparing the exercise practices of those runners to the habits of native people and animals, Dr. Dardik said that animals and natives in the wild run in short bursts. Then they take a little time to rest. And they repeat this cycle of exertion and recovery. He concluded that long-distance runners die of heart attacks because they have not trained their hearts to recover. (This is the same conclusion I reported in my bookThe Doctor’s Heart Cure.)

Based on these observations, Dr. Dardik developed his fascinating concept of viewing the heart’s exertion and recovery when you exercise as a wave – the “Heart Wave.”

When you begin an exercise, your heart rate starts to climb. When you stop, it starts to come back down. If you plot these changing rates over time – going up, then down – it does, indeed, form a wave.

Inside that wave of exertion, you have smaller waves from each heartbeat -alternating waves of exertion (systole) and recovery (diastole). Dardik was the first to see these as “waves within waves.” The illustration below will help you visualize it.

What this means is that if you mimic the natural rhythms of your heart by exercising in intervals of exertion and recovery, you will gradually increase your heart rate variability (HRV). Simply stated, the greater your HRV, the better your overall health. The more limited your HRV, the greater your risk of chronic disease.

In addition to increasing their heart rate variability, previously non-athletic women in Dr. Dardik’s study also developed:

For this exercise, you can choose any activity that will provide exertion for your heart. A treadmill, elliptical machine, bicycle, jumprope, or trampoline will work well, as will alternate sprinting and walking. (Of course, if you have a heart problem you should check with your personal physician before doing any exercise.)

To maximize the amplitude of your heart wave, keep your exercise interval brief. Thirty seconds is enough. Immediately upon finishing this brief sprint, put emphasis on your recovery. Instead of merely resting, participate in the process by calming your mind and imagining your heart rate slowing down.

To help with this, focus on each exhalation. As you breathe out, use your imagination to bring your heart rate down. In your mind’s eye, see your heart relaxing – slowly and steadily returning to its resting rate. When your heart rate recovers, do another interval.

Today’s Action Plan: Here’s a sample program you can do in about 10 minutes. And – unlike the drudgery of the much-touted aerobic regimens – this one is fun, and your benefits will be fast.

Progressivity – a principle that Dr. Dardik neglected – is the first principle of my trademarked PACE® (Progressively Accelerating Cardiopulmonary Exertion) program. The idea is that by making incremental increases in the intensity of your exercise, you will continue to change your body through time.

By the time you’re on the above program for six weeks, you should be giving the 20-second interval all you’ve got … then quickly changing your focus to recover as fast as you can. That will focus your training on increasing your heart rate variability.
