(HealthDayNews) -- Who's doing more work, a 150-pound man jogging for a mile barefoot or a 149-pound man jogging for a mile wearing a pair of running shoes that weigh a total of one pound?
That's the same total weight going the same distance, but the second man is working harder than the first one, according to the Journal of Applied Physiology.
A team from the Thermal Physiology Research Group in Soesterberg, The Netherlands, studied the workload imposed by footwear. They found that the extra workload produced by a pair of heavy shoes can be 2 to almost 5 times as much as the work of carrying the same amount of extra body weight.
So for a maximum workout, you might want to add army boots to your tank top and running shorts.
