力竭追赶训练对两种鲤科鱼类呼吸循环系统参数和力竭运动后代谢特征的影响

THE EFFECT OF EXHAUSTIVE CHASING TRAINING ON PARAMETERS OF RESPIRATORY AND CIRCULATORY SYSTEM AND EXCESS POST-EXERCISE OXYGEN CONSUMPTION IN JUVENILE QINGBO (SPINIBARBUS SINENSIS) AND ROCK CARP (PROCYPRIS RABAUDI)

  • 摘要: 为了考察力竭追赶训练对中华倒刺鲃(Spinibarbus sinensis)和岩原鲤(Procypris rabaudi)幼鱼呼吸循环系统和力竭运动后代谢特征的影响, 在(25±0.5)℃条件下, 将2种实验鱼各60尾 体重分别为(28.36±0.08) g和(19.53±0.13) g随机等分成对照组和训练组, 训练组进行1次/d共21d的力竭追赶训练。随后测定各组实验鱼的心脏和鳃指数、血液指标以及力竭运动后过量耗氧(Excess post-exercise oxygen consumption, EPOC)。结果发现: 2种鱼心脏指数、鳃指数、血红蛋白含量和红细胞数目在各自对照组和训练组之间都没有显著性差异; 岩原鲤对照组的鳃指数显著低于中华倒刺鲃对照组(P<0.05), 但心脏指数、血红蛋白含量和红细胞数目与中华倒刺鲃对照组无显著性差异。中华倒刺鲃训练组的运动前代谢率、运动代谢峰值、峰值比率、代谢恢复速率与其对照组没有显著差异, 但运动后恢复时间和过量耗氧显著大于对照组(P<0.05); 岩原鲤训练组的运动前代谢率显著低于其对照组(P<0.05), 但运动代谢峰值、峰值比率、运动后恢复时间、过量耗氧、代谢恢复速率与其对照组没有显著性差异。岩原鲤对照组的运动前代谢率、运动代谢峰值、过量耗氧和代谢恢复速率分别显著低于中华倒刺鲃对照组(P<0.05), 但峰值比率和运动后恢复时间与中华倒刺鲃对照组无显著性差异。研究表明: (1)力竭追赶训练对中华倒刺鲃和岩原鲤幼鱼的呼吸和循环系统参数没有产生显著性影响; (2)力竭追赶训练显著提高了中华倒刺鲃幼鱼的无氧代谢能力; (3)中华倒刺鲃幼鱼力竭运动前后代谢率显著高于岩原鲤幼鱼, 这可能与其较为活跃的习性有关。

     

    Abstract: To investigate the effects of exhaustive chasing training on parameters of respiratory and circulatory system and excess post-exercise oxygen consumption (EPOC) in juvenile qingbo (Spinibarbus sinensis) and rock carp (Procypris rabaudi), sixty samples of S. sinensis (28.36±0.08) g and sixty samples of P. rabaudi (19.53±0.13) g were randomly divided (equally 30 fish in each group) into control group and training group, respectively. Then, these fish in the training group were analyzed under exhaustive chasing training once per day for 3 weeks at 25℃ to measure the heart index, gill index, hematological parameters, and EPOC. The results showed that there were no significant differences in the heart index, gill index, hemoglobin content, and number of red cells between the control group and training group of S. sinensis and Procypris rabaudi(P<0.05). The gill index in the control group ofP. rabaudi was significantly lower than that in the control group of S. sinensis(P>0.05), whereas the heart index, hemoglobin content, and number of red cells in the control group ofP. rabaudi were not significantly different than that in the control group of S. sinensis(P<0.05). No significant differences were found in pre-exercise metabolic rate, peak post-exercise metabolic rate, factorial metabolic scope, and recovery rate between the control group and training group (P>0.05), whereas duration of EPOC in the training group was significantly higher than that in the control group ofS. sinensis (P<0.05). The pre-exercise metabolic rate in the control group was significantly lower than that in the training group (P<0.05), whereas peak post-exercise metabolic rate and factorial metabolic scope, duration of EPOC, and recovery rate in the control group were not significantly different than that in the training group ofP. rabaudi(P>0.05). The pre-exercise metabolic rate, peak post-exercise metabolic rate, EPOC magnitude, and recovery rate in the control group ofP. rabaudi were significantly lower than that in the control group of S. sinensis(P<0.05), whereas factorial metabolic scope and duration of EPOC in the control group ofP. rabaudi were not significantly different than that in the control group of S. sinensis(P>0.05). Our results suggested that (1) exhaustive chasing training had no significant effects on the parameters of respiratory and circulatory system ofS. sinensisandP. rabaudi(P>0.05); (2) exhaustive chasing training significantly increased anaerobic capacity ofS. sinensis(P<0.05); and (3) the pre-exercise metabolic rate and peak post-exercise metabolic rate ofS. sinensis were significantly higher than those of P. rabaudi(P<0.05), which may be related to active habits ofS. sinensis.
