quasi-isometric

quasi-isometric

term introduced 1997-1998 by Legg and Spurway, to indicate the condition in which muscles, though not strictly isometric, nonetheless remain for many tens of seconds under load sufficient to restrict blood flow substantially and thus produce metabolic and hence fatigue effects virtually indistinguishable from those experienced during strictly isometric contraction, sustained for similar time under equivalent load. Occurs for example in quadriceps of a dinghy sailor in a fresh breeze or of a jockey standing in stirrups.
