Warning:  Before reading this blog, consider that I could be just another person looking to justify doing the things they love to do – in spite of some evidence indicating that very activity is potentially harmful to health.


About a month ago, I wrote a blog that looked at research asking if endurance exercise is actually detrimental to your health. Over the last few weeks, I’ve given this blog and the research considerable thought. One of the first things that came to my mind was research that indicated as much as 90-percent of research is flawed. I looked at this issue in my blog “Are researchers just a bunch of manipulative liars?”


I also went back and read the research paper I referenced in last month’s blog. A couple of thoughts came to mind:

  • Though the research noted, “Serologic markers of cardiac damage, including cardiac troponin, creatine kinase MB, and B-typenatriuretic peptide, have been documented to increase in up to 50% of participants during and after marathon running” – I kept thinking, “What about the other 50% of the people?” If this is a genetic issue – perhaps I’m one of the lucky ones? Maybe I'm one of the "other" 50%  that is not negatively affected?
  • I also considered the cardiac changes in mice forced to do endurance exercise via electric shock. My thought was, “Of course they would show stressful cardiac changes – they were being electrically forced to run!”
  • In none of the studies cited in the research paper were 100% of the people adversely affected by high intensity or long duration exercise. This leaves me to wonder about the people that were not adversely affected – did they live longer? Are their lives somehow better?


One of the athletes I coach sent me a link to a New York Times column noting that researchers believe due to our endurance capabilities as humans, we developed bigger brains. Our very existence is due to  endurance exercise.


Ah ha! There – proof that endurance exercise is good.


I also read a column about 91-year-young Sven Wiik that was an Olympian, “was always fixated on sports” and still skis nearly every day.


Ah ha! Here’s a living example of someone immersed in sport that is an excellent, healthy 91.


Then, across my desk came research that Olympic medalists live an average of 2.5 years longer than the general population.


Few athletes workout longer and more intensely than Olympians and they enjoy longevity. Perhaps some this longevity is due to endurance exercise  past the age of 40?


After mulling all of this around in my head for awhile, I decided that I enjoy endurance sport. I love doing long bike rides, long runs and hours of Nordic skiing. Research does interest me, but I also understand the limitations of any research on human beings. We are complicated and it is impossible to account for controlling all the variables in any research study, including genetic influences.

 

All things considered, I plan to continue doing the endurance sports and racing that I love to do – until the time when I no longer feel like doing those sports. I figure I’m on the earth for a limited amount of time and I plan to take personal responsibility for spending my time as I please while I’m here.


I might cut years off of my life or suffer cardiac changes that aren’t healthy.


Or, I might live to be over 100 still doing endurance sports making researchers ask “Why? How?”

 

How do you plan to spend your time on earth?

I wrote a recent column on balance exercises. Not only do these exercises help your balance and strengthen your ankles, they help with balancing coordination right to left side.


There’s an easy way to add balance work to your dailyhabits. It works best if you have an electronic toothbrush that alerts you to 30-second segments to brush each section of your teeth.

With each segment (inner lower teeth, outer lower teeth, inner upper teeth, and outer upper teeth) alternate left leg, right leg, left leg and right leg for 30-second segments. Of course you can go for one-minute per leg too.


Depending on how often you brush your teeth, you can get some two to six minutes of balance work accomplished every day!

 

Thanks to Janet Saxon for this trick.
