High-Intensity Walking

High-Intensity Walking

The program consisted of repeated intervals of three minutes of fast walking, aiming for an exertion level of about six or seven on a scale of one to 10, followed by three minutes of slow strolling. The results turned out to be very promising. As reported by the New York Times:1
“In their original experiment, the results of which were published in 2007, walkers between the ages of 44 and 78 completed five sets of intervals, for a total of 30 minutes of walking at least three times a week.
A separate group of older volunteers walked at a continuous, moderate pace, equivalent to about a 4 on the same exertion scale.
After five months, the fitness and health of the older, moderate group had barely improved. The interval walkers, however, significantly improved aerobic fitness, leg strength and blood-pressure readings.”
