Dr. G. John Mullen in Swimming World Magazine wrote about the benefits of swimming. “When you compare swimming to running, you can burn more calories swimming laps around the pool than you can running laps for an hour. One hour of vigorous lap swimming can burn as much as 715 calories. The same amount of time running at 5 mph burns only 606 calories.”
