The solution to that dilemma is simple. It is the MET, which stands for metabolic equivalent. The MET is the ratio of work metabolic rate to resting metabolic rate. 1 MET equals 1 kilocalorie per kilogram of weight per hour of expended energy which is the amount of energy we all use while at rest. While at rest, your MET=1. Walking at a brisk 3.0 mph, your MET=3.5. This means that during a brisk walk, you are expending 3-1/2 times more energy than when at rest.
Here are some MET values and their associated activities to help you better understand the flexibility that the MET offers.
MET=2.0 —-standing, making a bed, washing dishes, walking slowly
MET=2.5 —-playing darts, billiards, musical instrument
MET=3.0 —-vacuuming, sweeping, slow ballroom dancing
MET=3.5 —-Walking at 3.0 mph
MET=4.0 —-table tennis, shooting basketballs, non-competitive volleyball
MET=5.5 —-mowing with a power mower
MET=6.0 —-bicycling at 10-12 mph, swimming, walking – 4.5 mph, tennis-doubles
MET=7.0 —-walking/hiking, non-competitive soccer
MET= 8.0 —-competitive volleyball, tennis-singles, jogging – 5 mph
MET=9.5 —-competitive soccer, bicycling – 14-16 mph, jogging – 6 mph
A comprehensive list of MET values and the associated activities can be found in my Smartphone and Tablet APP, “healthylc.” The APP and the MET chart are a free download.
Having used the MET for many years, I can say that planning and implementing my exercise routines has been easy. I walk briskly (3.0 mph) for about 1 hour or more at least 3 times a week. This is the exercise at which we all get the most aerobic benefit with the least amount of effort. If I want to cut my exercise time in half, I can jog between 4.5 and 5.0 mph because I am expending twice as much energy (MET=7.0) as when walking briskly (3.5 mph). By doing the math, developing and implementing an exercise plan that meets your fitness goals can be easy for you too.
