Ground reaction forces (GRFs) may provide a surrogate measure for the strain ... The jumps measured were drop jumps from 10, 30, and 50 cm, all followed by a plyometric jump, submaximal and maximal ...

For example vertically, the pull of the Earth down on the body is cancelled out by the combined upward push of the reaction force and the friction force. Considering the forces acting along the ...

Objective—To examine the effects of instructions related to joint kinematics, auditory stimuli, and imagery on lowering the vertical ground reaction forces associated with landing from a jump. Study ...
