plate

 [plāt]
1. a flat stratum or layer.
2. dental plate; sometimes, by extension, incorrectly used to designate a complete denture.
3. a flat vessel, usually a petri dish, containing sterile solid medium for the culture of microorganisms.
4. to prepare a culture medium in a petri dish, or to inoculate such a medium with a bacterial culture.
axial plate primitive streak.
bite plate biteplate.
cortical plate a layer of compact bone overlying the spongiosa of the alveolar process on the vestibular and oral aspects of the mandible and maxilla.
deck plate roof plate.
dental plate a plate of acrylic resin, metal, or other material that is fitted to the shape of the mouth, and serves for the support of artificial teeth.
dorsal plate roof plate.
end plate see end plate.
epiphyseal plate the thin plate of cartilage between the epiphysis and the shaft of a long bone; it is the site of growth in length and is obliterated by epiphyseal closure.
equatorial plate the collection of chromosomes at the equator of the spindle in mitosis.
floor plate the unpaired ventral longitudinal zone of the neural tube; called also ventral plate.
foot plate footplate.
force plate force platform.
medullary plate neural plate.
muscle plate myotome (def. 2).
neural plate a thickened band of ectoderm in the midbody region of the developing embryo, which develops into the neural tube; called also medullary plate.
roof plate the unpaired dorsal longitudinal zone of the neural tube; called also dorsal plate and deck plate.
tarsal plate tarsus (def. 2).
ventral plate floor plate.

force plate

A flat, floor-mounted instrument, similar to a scale, for determining weight-bearing loads and biomechanical forces placed on the foot during walking or running. It is used to detect subtle body movements in order to identify postural deficits, or to develop (in athletes or people with balance disorders) more fluid and safer coordination and locomotion.

In this case, the torques of both the hip motor and knee motor increase dramatically because of the ground reaction force.
Plantar pressures have also been evaluated in the Zuni Exercise[R] system reporting a significant reduction in ground reaction forces during walking and running [12].
Data analysis included ground reaction force, power, and jump height.
This is probably due to the lack of statistically significant differences of insoles made because of a combination of a bridge port has high hardness Despite having Peron layer, there is sufficient flexibility in the floor, so the floor cannot effectively absorb the ground reaction force and will continue to diminish.
Soccer involves intermittent high-intensity activities like running at different intensities, sudden accelerations and stops, rapid changes in direction, jumps, kicking and punting that result in significant ground reaction forces on the skeleton.
Cushioned running shoes may attenuate the ground reaction force better for high arched runners (33) and motion control shoes may control instantaneous loading rates better for low arched runners.
Top sprinters generate higher propulsive ground reaction force impulses during the initial acceleration phase that enable them to reach their top speeds more quickly and do, in fact, produce higher muscular joint moments than merely good sprinters.
This possibly explains reports of altered ground reaction force profiles (Zadpoor and Nikooyan, 2012) and reduced shock attenuation (Mercer et al.
It was interfaced with a personal computer running custom LabVIEW software (version 2013, National Instruments, Austin, TX) that collected and analyzed dependent variables of peak ground reaction force (GRF) and rate of force development (RFD).
Leung and colleagues also examined the impact of UC Avrtvz JBL ground reaction forces, a significant difference between the two modes on the vertical component at the top of the shoes and insoles the shoes I saw the results of the present study is in agreement [7] and the study of viscoelastic shoe insoles Nyg and colleagues in relation to the impact on ground reaction force on the runners, no difference was observed using insole force to deal with the results of the present study is consistent with the conventional insoles.
There are two ways that exercise stimulates new bone: One is by muscle force (the pull of a muscle at its attachment to the bone), and the other is ground reaction force (the force exerted by the ground on a body in contact with it).
