摘　　要：在25℃饥饿和维持日粮(1.5%体重)条件下,测定了连续15d无氧运动锻炼(追赶至力竭)及随后5d撤消运动锻炼过程中南方鲇(Silurus meridionalis)静止代谢率(VO2rest)的变化。实验以饥饿和维持日粮条件下非运动锻炼组分别作为饥饿及摄食对照组。研究发现:饥饿和摄食对照组的VO2rest在实验过程中显著下降(P<0.05),饥饿锻炼组VO2rest在锻炼的4～15d显著上升(P<0.05),而摄食锻炼组的VO2rest相对稳定;当撤消锻炼后,饥饿和摄食锻炼组VO2rest迅速下降,与对照组无显著差异。研究表明,相对于对照组,4～7d的无氧运动锻炼导致VO2rest显著上升;而撤消锻炼后,15d的锻炼影响在3～5d内完全消除。实验还提示,与维持日粮处理比较,饥饿条件下无氧运动锻炼对VO2rest的影响更为显著。The resting metabolic rate （VO2 rest ） of Silurus meridionalis was measured under treatment of starvation and of maintain ration level （1.5% wt） during 15 d anaerobic exercise training （5 min chasing） and then following 5 d resting at 25℃ .Two groups of fish either on fast or feeding at maintain ration level （1.5% wt） but without exercise training were treated as control. VO2 rest of both feeding and fasting control groups were significant decreased during experiment （ P 〈 0.05）. VO2rest, of fasting training group was significantly increased after 4 to 15 days training （ P 〈 0.05） while VO2rest, of feeding training group was relatively unchanged, VO2rest, of both training groups were significantly decreased to the similar level of the control groups after 3 to 5 days without training. It suggested that VO2 rest, Was increased after 4 to 7 days anaerobic exercise training. While the influence of training was eliminated after 3 to 5 days resting. It also suggested that training had more profound effect on VO2 rest, in fasting group than in feeding treatment.
