Lastly, the results confirm that the increase in force required in the antigravity muscles acting to extend the knee had no effect on SV or a-v[O.
Have the patient flex and extend the spine; these movements often exacerbate pain resulting from VCE Moderate muscle spasm or splinting may occur as the antigravity muscles of the spine attempt to unload the pressure on the wedged anterior vertebral body.
During typing, wrist and elbow postures are maintained for long periods, creating static loading in the antigravity muscles - namely, the wrist extensors.
Many of these experiments probed adaptations of the so-called antigravity muscles, which support the body and maintain posture in Earth's gravity.
