Restoration of Peak Vascular Conductance After Simulated Microgravity by Maximal Exercise.

Abstract

We sought to determine if: (1) peak vascular conductance (Gmax) of the calf was reduced following exposure to prolonged simulated microgravity, and (2) if maximal cycle ergometry performed at the end of microgravity exposure stimulated a restoration of Gmax. To do this, Gmax was recorded following ischemic plantar flexion exercise to fatigue in seven men after 16 days of head-down tilt (HDT) under two conditions: (1) after one bout of maximal supine cycle ergometry completed 24 hr prior to performance of ischemic plantar flexion exercise, and (2) in a control (no cycle ergometry) condition.
