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
