linthorne paper title - answer✔analysis of standing vertical jumps using a force platform
3 methods to calculate jump height - answer✔1. flight time (kinematic eqns)
2. impulse momentum thm applied to the force time curve
3. work energy thm applied to force displacement curve
force platform analysis of standing vertical jump allows us to study - answer✔kinematics and
dynamics of 1D motion
curves of velocity and displacement of com obtained from - answer✔F vs t --> /m --> a vs t -->
integration
force platform measures - answer✔the force exerted on it by a subject
(using N3 law this also gives force exerted by the platform on the person (GRF))
standing vertical jump types (2) - answer✔countermovement jump and squat jump
countermovement jump involves - answer✔a stretch shortening cycle
stretch shortening cycle - answer✔prestretch muscles before shortening

stretch shortneing cycle enhances - answer✔force production and work output
net vertical forces acting on a body - answer✔Fgrf and mg
direct jump height measurement involves - answer✔using the height of the heels at max using
a meterstick
direct jump height measurement purpose - answer✔serves as a baseline for later calculations
indirect jump height measurements use - answer✔velocity of com at takeoff and energy
conservation
review linthorne graphs - answer✔
linthorne jump phase a - answer✔starting upright and stationary (height=0)
linthorne jump phase a-c - answer✔unweighting bc GRF<BW
linthorne jump phase a-b - answer✔jumper relaxes leg and hip muscles --> hips and knees flex
under gravity
Fgrf-mg=- (a downward)
linthorne jump phase b - answer✔max downward acceleration
linthorne jump phase b-c - answer✔leg muscle activation starts but com decreases
Fnet = -
linthorne jump phase c - answer✔GRF=BW Fnet=0 max decreasing velocity
