| Research Abstract |
Exercise-induced venoconstriction of inactive limb is thought to be controlled by sympathetic nerve system. However, the mechanisms are not clear. The increase in sympathetic nerve activity during exercise is caused by central command and the reflex neural mechanism which is activated by exercise. Thus, the purpose of this study was to investigate whether reflex arising in chemically and mechanically sensitive muscle afferents(muscle metabo-and mechano-reflex) contributed to the venoconstriction of resting limb during exercise. The primary findings were that 1) sympathoexcitation via muscle metabo-reflex may contribute to the exercise-induced venoconstriction, but 2) the muscle mechano-reflex effects rarely on the venoconstriction during exercise.
