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 ...

The normal reaction force always acts at right angles to the ... curriculum-linked resources to help deliver lessons - all arranged by subject and age group.

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 ...
