Researchers at the University of Leeds in the United Kingdom have measured the effort required to walk on a treadmill while wearing a full suit of armor.
A complete outfit of late 15th century armor, with cuisses, greaves, and sabotons, weighs as much as 50 kg or 110 pounds. It was hard to find subjects who knew how to move in armor or were strong enough to carry that weight. But some historical interpreters from the Royal Armories were up to the task.
They found the replica outfit remarkably flexible -- they could even do cartwheels in it. But extended moving around took a toll. By measuring heart rate and respiration, researchers calculated that it took 2.3 times more effort to walk in the suit compared to normal walking, and 1.9 times more effort to run in it.
