Can a muscle fatigue after 2-3min work, at sub-maximal loads? Indeed it can.
Muscle fatigue can be predicted by the tension time index (TTdi), a tool developed by Clanton & Grassino in the 1980's. A tension-time index of 0.15 can predict fatigue when a muscle works indefinitely. The TTdi is the product of normalised force * contraction time/contraction-relaxation time.
