Physiological effects of wearing armour and heat

I find this reasoning floored, as it is putting our 21st century stamina levels on people from a different realm, where there were very few office jobs, and most ran a shovel or whatever for a living, and knights trained every day, not once in a flood.

To put it in a friends Scottish terms, "they were tough wee sods!"

( Another example is the warbow, who now, apart from a very few, can draw 150 lbs?...with some going up to 190 lbs?) "tough wee sods" sounds about right.....

What worries me David, is that such a test can be done in television or whatever, and it soon becomes "truth" by repetition.
I think it's best to just go with first-hand accounts, and I'd love to read some of "how it was" in battle.

Best wishes,

Hi Richard ,
I should have made the point more clearly. I totally agree that these men were 'physically conditioned' to cope with the demands of battle.....afterall being unfit was potentially lethal However, some accounts state that hand to hand fighting could last for hours, due to the dehydration it was physically impossible to maintain that level of effort ...no matter how well 'conditioned .... it would be suicide to continue fighting whilst suffering dehydration....not only do you have muscular cramps....it also affects the 'clarity' of the mind. Let me put it this way....in any survival situation....drinkable water is a priority....you could survive for days without food or shelter.

Another thing I have noticed is that armour evolution increased the thickness and hardness of the plate and increased the number of 'parts' to increase mobility and protection. To lessen gaps in the armour would increase the 'heat up' factor. Helmets became more 'enclosed' and the 'breathing' holes / slits became smaller to prevent 'stabbing' to the area, which again would increase 'heat' and restrict oxygen intake. It suggests to me that designers had protection as the critical factor, not the conditions suffered by the wearer. Men at arms would have to 'work around' the problems.....short 'breaks' to rest and take on water would be the obvious remedy ....in a 'drawn out' battle.

I also have to agree about the war bow situation, English archers were well trained and exhumed bodies of archers have significantly larger bone mass in their draw arm (through repetition, the bone structure would 'enlarge' as the muscle mass increased) ....I doubt this physical 'abnormality' would occur in a 'modern' archer.
This is an interesting link...
