Simulations of a knee extension exercise during isometric (solid line) and isometric-shortening-isometric (dashed line) contractions. The quadriceps muscle were fully activated at 0 sec and remained active throughout the simulation. The isometric test was conducted at 60 degrees and the isometric-shortening-isometric test began at 100 degrees and underwent constant velocity shortening to 60 degrees.
