An a-posteriori multicentre reliability study was conducted to compare the reliability and magnitude of the maximum power (P_(max)) and optimal velocity (V_(opt)) between the force-power-velocity relationships during the leg cycle-ergometer and bench press throw exercises. The force-power-...
However, the shortening velocity at peak power output was elevated 13% in the post-BR fibers, which partially compensated for their lower force. Post-BR fibers from these same seven subjects also displayed a reduced sensitivity to free Ca2+ (P < 0.05). These results indicate that the reduced...
Use this calculator to determine the velocity of a moving object in mile per hour, kilometre per hour, knot, metres per second or feet per second units, with a defined power output and force applied v=P/F
Pull force-velocity (r2 = 0.99) and peak instantaneous force-velocity (r2 = 0.93) relationships were linear. Stroke power (r2 = 0.98), pull power (r2 = 0.99), and instantaneous peak power (r2 = 0.99) were quadratic, with apexes at 2.04, 3.25, and 3.43 m x s(-1), respectively. ...

Exercise in space: human skeletal muscle after 6 months aboard the International Space Station Peak power was 32% lower (P < 0.05) after spaceflight. Force-velocity characteristics were reduced (P < 0.05) -20 to -29% across the velocity ......
The aim was to compare lower-limb power, force, and velocity capabilities between squat and leg press movements. Ten healthy sportsmen performed ballistic lower-limb push-offs against 5-to-12 different loads during both the squat and leg press. Individual linear force-velocity and polynomial power...
The internal shear force in a steady flow of a viscous fluid is proportional to the velocity gradient. If the flow is in the x-direction and the speed of the flow is distributed in the y-direction, i.e., the flow velocity in the x-direction, u, is a function of y, the shear for...
The power into the skin is given by PZ2 = pZ2 υZ2 where p is the pressure across Z2 and υ is the velocity of Z2. (14.24)PZ2Pin=pZ2υpinυ=pZ2pin=Z2Z1+Z2 Note that the impedances are given in MKS units, not the cgs units used throughout this text. However, since ...
The ability of the human body to generate maximal power is linked to a host of performance outcomes and sporting success. Power-force-velocity relationships characterize limits of the neuromuscular system to produce power, and their measurement has been a common topic in research for the past centu...
