THE EFFECT OF AEROBIC EXERCISE TRAINING AND FEEDING ON EXCESS POST-EXERCISE OXYGEN CONSUMPTION IN JUVENILE QINGBO (SPINIBARBUS SINENSIS)
摘要
Abstract
To investigate the effects of aerobic exercise and feeding on excess post-exercise oxygen consumption (EPOC) in juvenile qingbo (Spinibarbus sinensis), 120 fish [(21.35±0.05) g, (10.21±0.03) cm] were exercised at 25℃under four water velocities, i.e., nearly still water (control), 1 body length (BL)/s, 2 BL/s and 4 BL/s for eight weeks to measure the heart index, gill index and EPOC. The results showed that the heart and gill indexes significantly increased in 4 BL/s training group compared to those in other three groups (P<0.05). Aerobic exercise resulted in a significant in-crease in the pre-exercise metabolic rate under both feeding and fasting status (P=0.001). There were no differences in the EPOC magnitude ofS. sinensis between the exercise groups and control group under both feeding and fasting status. Peak post-exercise metabolic rate and increment of metabolic rate were significantly higher in the 4 BL/s trai-ning group than those of the control group under fasting status. Peak post-exercise metabolic rates and increment of metabolic rates were significantly higher in the three exercise groups than those of the control group under feeding status (P<0.005). Feeding resulted in a significantly higher pre-exercise metabolic rate compared to fasting fish under the same water velocity (P<0.001). Peak post-exercise metabolic rate is similar between the feeding and fasting treat-ment groups with the same water velocity. Feeding led to a significant decrease in the increment of metabolic rate and EPOC magnitude in the control group (P<0.05). Our results suggest that aerobic exercise significantly increased ae-robic capacity, which may be related to the improvement of respiratory and circulatory system function, and that ex-haustive exercise can induce maximum oxygen consumption rate, and that feeding reduced the anaerobic capacity in ju-venileS. sinensis.关键词
