Hello: I'm trying to find "good" measurement for force, distance and time for a treadmill. I'm assuming the force will simply be the "weight" of my body but the distance..the distance is a different issue altogether. Since we're contrained in not using the data from the machine, I must use simple devices in my disposal i.e. metre sticks, bathroom scales, stop-watches, etc. How would I calculate good "distances" assuming I'm not setting the treadmill on an incline (that is, if I don't "have" to set it on an incline). Can I just calculate the average distance between my legs and multiply that by the number of steps I take? I must also calculate... 1). Energy conducted away by vaporizing sweat. 2).Energy that has been radiated away by my body during the workout. 3).heat energy stored in excess body temperature. 4). Amount of heat energy lost by convection 5). total food energy used 6). heat energy created during the work-out. Also, what happens to the energy stored as excess body heat as my body cools down to normal temperature? Any help would be appreciated. Thanks.
