Auxotonie
Definition
A physiological phenomenon or process consisting of a muscular contraction during which the internal tension of the fibers progressively increases concurrently with the shortening of their length; a mechanical activity regimen characteristic of the myocardium during the blood ejection phase or skeletal muscles overcoming a variable elastic resistance.
