We tested the hypothesis that static contraction causes greater reflex cardiovascular responses than dynamic contraction at equivalent workloads [i.e., same tension-time index (TTI), holding either contraction time or peak tension constant] in chloralose-anesthetized cats. When time was held constant and tension was allowed to vary, dynamic contraction of the hindlimb muscles evoked greater increases (means +/- SE) in mean arterial pressure (MAP; 50 +/- 7 vs. 30 +/- 5 mmHg), popliteal blood… CONTINUE READING
