【Share】Defining "moderate-intensity" exercise
|
|||
|
Engage in moderate-intensity physical activity for a minimum of 150 minutes each week. That's the current national recommendation on physical activity. It's easy enough to understand, except for the "moderate intensity" part. Does that mean walking? So-called "brisk" walking? Jogging? San Diego State University researcher Simon Marshall has come up with a practical rule of thumb for figuring out "moderate intensity" as it applies to walking: it's akin to taking at least 100 steps per minute. To get to this definition, Marshall and his colleagues recruited 97 women and men. Each walked on a treadmill four times at four different speeds—from 2.4 miles per hour to 4.1—while a machine measured the amount of energy he or she was expending. The volunteers also wore pedometers to count their steps. Complex calculations later, the researchers determined that walking at a speed of at least 100 steps per minute fulfilled the lower limit of moderate-intensity exercise (American Journal of Preventive Medicine). |
