A schematic showing force traces from different muscle models for simulated muscle ergometer test. The classic Hill-type muscle model does not reproduce any aspects of shortening induced force depression. Static force depression (ΔF_static) occurs throughout the test, while transient force depression (ΔF_trans) occurs during the transient recovery period which begins when the muscle stops shorting (F_trig). In order to accurately reproduce experimental data, both ΔF_static and ΔF_trans is included.
