- QUESTION: Would you be willing to solve a small problem for me? Please
- compare two men who are exercising. One is walking, and finishes 3 miles in 1
- hour. The other covers the same course by running at 6 miles an hour. Who is
- burning the most calories? Do both exercise periods yield the same health
- benefits? I am sure there must be a formula for all of this.
-
- ------------------------------------------------------------------------------

- ANSWER: Great question! Even though math is not one of my strong points,
- there are some simple formulas to help. For the purposes of a valid
- comparison, I chose to make both men the same age, 45 years old, both weigh
- 175 pounds, and both are 5 foot 10 inches tall. That's pretty average. The
- walker covers the course at 3 miles per hour and burns 278 calories. Not bad.
- The runner, at 6 miles per hour, covers the same course in 30 minutes, and
- burns . . . 278 calories. His only advantage is that he finishes faster.
- However, since the slow walker had a longer sustained period of exercise, it
- is probable that he burned more fat than the runner did, since we gain our
- calories from fat and lose them after a sustained exercise of 20 minutes or
- more. Since his pulse rate was elevated for a longer period of time, he most
- probably improved his cardiovascular reserves. That means he strengthened his
- heart a bit, probably had a positive effect on any elevated blood pressure,
- and gave a boost to his immune system.
- These answers are easy to explain. Since the formula for caloric burn
- from exercise depends upon distance, sex, age, and your height and weight,
- the results are the same for both men in this example. However, if you wish
- to include the other benefits of exercise in a calculation of health benefits,
- time plays an important role. Thus the person who exercises for longer
- periods of time, or works out more frequently, will show the greatest gains.
- All of this may be quite pleasing to you if you are the slower man in the
- example, as I suspect you are. I know it gives me a measure of satisfaction
- as the younger guys fly past me on the track, yet are long gone by the time I
- have finished. For I know, as you now know, that it is indeed the turtle who
- often wins the race; for health, that is. If you doubt me, check out the life
- expectancy of a turtle versus a hare.
