Earth shattering! Next thing we’ll hear is that breathing oxygen is essential for life or living. Wow!

Get moving or you know what will happen!

This is new research and ground breaking, “Physical Fitness Cuts Heart, Death Risk Study Shows Cardiorespiratory Fitness Helps Reduce Risk of Heart Disease” from WebMD Health News written By  Jennifer Warner and reviewed by Elizabeth Klodas, MD, FACC.

Good thing we had a doctor to review this research, here’s the research in a nutshell, get moving or die. I just saved all those doctors years of medical school and research. Here’s the article as it appears online:

People who are physically fit, as measured by a high level of cardiorespiratory fitness (CRF), are less likely to develop heart disease and less likely to die from any cause, a study shows.

Researchers say it’s rare for doctors to consider cardiorespiratory fitness in evaluating a person’s risk of future heart disease or death, mostly because the degree of risk reduction associated with different levels of physical fitness was unclear.

But a review of studies shows that people with a low level of cardiorespiratory fitness have a 70% higher risk of death from any cause compared with those with a high level of fitness.

“We suggest that CRF, which can be readily assessed by an exercise stress test, could be useful for prediction of [heart disease] and all-cause mortality risk in a primary care medical practice,” write researcher Satoru Kodama, MD, PhD, of the University of Tsukuba Institute of Clinical Medicine in Ibaraki, Japan, and colleagues in the Journal of the American Medical Association. 

Cardiorespiratory Fitness for Long Life

In the review, researchers analyzed the relationship between physical fitness, expressed by cardiorespiratory fitness, and the risk of death found in 33 different studies involving nearly 190,000 people.

Cardiorespiratory fitness is measured through exercise stress testing, in which participants typically exercise by walking on a treadmill until they become fatigued or feel exhaustion. CRF was then estimated as maximal aerobic capacity expressed in metabolic equivalents (METs).

METs indicate the amount of oxygen the body consumes during activity and represents a standard scale on which to measure exercise workload. One MET is equivalent to the oxygen the body uses at rest.  Being able to attain a high degree of oxygen use during exercise, and therefore have a high MET level, is an indicator of physical fitness. 

The researchers found that compared to those with a high CRF, those with low cardiorespiratory fitness had a 70% higher risk of death from any cause and a 56% higher risk of heart disease events, such as heart attack or stroke. Compared to those with an intermediate level of physical fitness, those with a low CRF had a 40% higher risk of death from any cause and 47% higher risk of heart events.

Researchers say a minimal level of cardiorespiratory fitness of 7.9 METs may be important for overall health. Expressed in terms of walking speed, men around 50 years of age should be able to walk at a continuous speed of 4 miles per hour and women should be able to walk 3 miles per hour, on level ground, or be able to complete at least six minutes of a standard treadmill stress test (which involves walking up an incline, but at a slower pace).

They found even a 1-MET increase in physical fitness was associated with a 13% lower risk of death from any cause and 15% lower risk of heart disease. To put that in perspective, the difference between riding a cart and walking while playing golf is 1 MET level.

I used to be a golf nut and realized after four or five years, of walking on the golf course as my primary form of exercise, that I had gotten fat. Yes, fat and “way” out of shape. Your workout doesn’t have to be training for a marathon but it does have to have some purposefulness, if that’s a word. What do I mean by purposefulness, I mean, that when you start working out, go slow. When you’ve built that physical base, then get really moving and build a program that you love so you can stick with it for life. 

MikeZ_i love to walk but that’s just me and i love to walk fast. the distance isn’t important but build toward 1 hour per day and you’ll stay healthy, no research required just the will and courage to start and start small. Build it from that point. i know you can do it, please start for yourself and all the people you love.

Please consult your physician before starting any exercise or weight loss program.
Your physician is your very best resource.
