if they are properly fastened in the seat, they shouldn't be holding their body against the brake pedal.

yer 100kgs is a bit much i personaly dont think a f1 driver dose that for a entier race lol i leg press 170kgs at the gym and no fing way in hell am i going to be able to do more then 5 sets of 10 even though i dont do it like that

i couldnt see it being 100kgs tbh

The Karting obviously didnt help much then

Well I have never known karting to be recommended by doctors to heal neck injuries lol

If you leg press 170kg, you should know how much easier it is to calf raise 170kg then. Dont forget the ROM and the leverages involved in the two exersizes. 100kg of pressure with the calf isn't as huge as people think in all honesty.

As for the G-Force question.. Well the drivers are very well strapped in, but their foot can obviously still rotate around the ankle joint. Foot n boot probably does weigh a couple of Kg maybe, so even if they were hitting 5g deceleration that's still only an extra 10kg on the brake pedal. Not a whole lot compared to 100kg really.

Plus, I'm willing to put money on that 100kg figure being a transient "peak" figure off the telemetry, not a sustained pressure over several seconds.

I agree it's not as amazing at it sounds IMO. I bet if you were to jump up and down on your toes on one foot you could be generating 2000N (equivelent of ~200kg) easily in short impulses...

And anyway, your body wants to move forwards relative to the car during braking so 100kg sounds easily achievable.

watching the press conference of Schumacher, his doctor said:

"He will be able to do sports again and I regret to say it, he will be able to ride motorcycles under racing conditions again." I lol'ed a bit about that passage... Even his doctor dislikes Schumacher's collection of highsiders^^

Is there any footage of his racing/accidents? I wouldn't mind seeing how he did. From the sounds of it he did alright for a newbie!
