Donning these replica suits — which were modeled on the armor of a 15th century London sheriff named William Martyn — forced the volunteers to expend approximately twice the amount of energy when engaging in cardiovascular activity.Emphasis mine. It goes on to say the researchers would like to test out different types of armor, but the verdict seems written on the wall--heavy stuff is HEAVY!
After physiologist Graham Askew of the University of Leeds monitored the mail-bedecked volunteers trudging and jogging on treadmills, the researchers discovered that wearing the armor resulted in volunteers using 1.9 times more energy while running and 2.3 times more while walking.
Given these findings, should encumbrance be further modified? Should there be a minimum Strength score to even WEAR certain types of armor? (Some games already do this, yes?). Get your fighters back to the gym!
