sci.muscle-fiber-force Calculator
Calculates muscle force-velocity relationship using the Hill equation: (F + a)(v + b) = (F₀ + a)b, where a and b are empirical constants. Maximum contraction velocity occurs at zero load — muscles produce less force at higher contraction velocities.
Inputs
Max Isometric Force N
Push or pull (N). F = ma. Net force determines acceleration. Account for all forces including gravity and friction.
Max Shortening Velocity Ls
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Shortening Velocity Ls
Speed in a specified direction (m/s). Required for momentum, kinetic energy, and wave calculations.
Results
muscle force F (N)
Sample size or count used in the calculation.
force-velocity ratio F/F₀
The proportional relationship between two quantities.
