[Regional blood flow during isokinetic dynamometric tests after 14-day bed rest].
Time-course variations in regional circulation during isometric and isokinetic loads of varying intensity were measured after 14-day head-down tilt. It was found that pulse blood filling of the leg decreased and its vascular response to the load varied. These findings suggest that the impairment of the strength-velocity properties of muscles after hypokinesia is associated not only with their morphological changes but also with their inadequate blood supply during loading.
