For skeletal muscle, the physiological meaning of Hill's hyperbolic force-velocity equation and the factors affecting it, such as the active state, method of velocity measurement and mode of stimulation, have been discussed. After the development of the sliding filament theory, Hill's equation was...
Isotonic quick-release protocols were used to measure the initial velocity of shortening following release from control wall tension (afterload) to a series of fractional afterloads. After release, the initial rates of shortening were fit to the Hill equation to obtain coefficients for a hyperbolic ...
The study's purpose was to determine the respective influences of the maximal power (Pmax) and the force-velocity (F-v) mechanical profile of the lower limb neuromuscular system on performance in ballistic movements. A theoretical integrative approach was proposed to express ballistic performance as...

The maximal force-velocity relation in the rising phase of the contraction can be described by Hill's (1938) equation with the following parameters (at 37°C): a/P<SUB> o </SUB> = 0.73±0.04, b = 0.5±0.04 lengths/s, V<SUB> max </SUB> = 0.74±0.02 lengths/s (n = 7, mean...
The equation for the formula of Force can be expressed in the form given below: F = ma Where, m = mass a = acceleration It is formulated in Newton (N) or Kgm/s2. Acceleration “a” is given by, a = v/t Where, v = velocity t = time taken So Force can be defined as F = ...
Lorentz force, the force on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after Dutch physicist Hendrik Lorentz) and i
speed of shortening and the load were fitted to the data for each muscle by the method of least squares using Hill's equation 2 (( P + a ) V = b ( P 0 − P ), where P 0 = maximum isometric tetanic tension, P = load, V = speed of shortening and a and b are constants)...
The magnitude of the electric force F is directly proportional to the amount of one electric charge, q1, multiplied by the other, q2, and inversely proportional to the square of the distance r between their centres. Expressed in the form of an equation, this relation, called Coulomb’s law...
