Theory 12/Seconds to Minutes/Muscle mechanics
Force Needs Activation Before Contraction
The claim
Peak muscle force is achieved only when the ratio of activation time to contraction time falls below a threshold, so fast movements never reach full force.
01Mechanism
Calcium release and crossbridge recruitment take time; if the contraction is faster than activation, only part of the motor pool contributes.
02Prediction
Force should fall as the ratio rises.
03Refutation
Force tracking recruitment alone would remove timing.
