    Notes: [Auszug] It can easily be shown that the rate of rise in tension in the extensor muscles is not fast, the peak being reached in about 20-30 msec (ref. 1). Investigation of the mechanical system shows that the lever arm of the extensor apodeme at the joint varies greatly with joint angle, while that of the ...
