水生动物的运动机制一直是动物学家感兴趣的问题。他所谓的“格雷的Paralysis”被证明是一个诱因，引起了兴趣，在游泳明能源和水生动物的流体动力学开花。1）虽然相当大的关注，从那时起，已支付给水上运动，相对较少的知道，所需的功率输出游泳，因为涉及的技术问题，在测量。然而，大多数方法都有一个共同的缺点，即很难将推力与实际游泳速度联系起来。至于间接测量，已经报道了各种方法。例如，BREiT '）通过测量氧气摄取量计算出幼红鲑鱼游泳所需的能量。当能量仅来自好氧过程时，该方法可以做出准确的估计，但在最大持续速度以上，其中能量主要通过厌氧过程获得，该方法不得不依赖于基于在好氧范围内艾德的数据的外推。WEBB，8'通过给鱼增加额外的阻力载荷，得到了推力或功率输出与游动速度的关系。虽然这种独特的方法可以覆盖整个游泳速度谱，但它不能产生关于红色和白色肌肉如何贡献特定速度游泳所需的功率输出的信息。本研究的目的是探讨这两种运动肌的功率输出和功能。本文将利用黄尾五斑红肌和白色肌的肌电图来估计各肌肉在各种游泳速度下产生的功率，并讨论各肌肉对游泳成绩的贡献。根据肌肉活动的特点，提出了鱼类运动的两个重要临界点。此外─
The mechanism of locomotion of aquatic animals has long been a matter of interests to zoologists. he so-called "Gray's Paradox" proved to be an incentive that caused a bloom of interest in swim ming energetics and the hydrodynamics of aquatic animals.1) Although considerable attention has been paid to aquatic locomotion since then, comparatively little is known of the power output required for swimming because of the technical problems involved in measurement. A few at tempts have been made to measure the thrust power directly.2-4) Most of the methods, how ever, suffer from the common disadvantage that it is difficult to relate the thrust power to the actual swimming speed. As for indirect measurements, various methods have been reported. For ex ample, BREiT') calculated the energy required for swimming by young sockeye salmon through the measurement of oxygen uptake. This method can make an exact estimation when energy is derived solely from aerobic process, but above the max mun sustained speed, where energy is derived largely through anaerobic processes, the method has to rely on extrapolation based on data obtain ed in the aerobic range. WEBB,8' by adding extra drag load to fish, obtained the relationship between the thrust or power output and swimming speed. Although this unique method can cover the whole spectrum of swimming speed, it does not yield information on how the red and white muscles contribute to the power output required for swim ming at a particular speed. It is the purpose of this study to examine the power output and function of these two types of locomotor muscle. In this paper, the electromyogram of the red and white muscles of the yellowtail Seriola quinqueradiata will be used to estimate the power produced by each muscle at various swimming speeds, and the contribution of each muscle to swimming performance will be discussed. As a result, two impor tant critical points in fish locomotion will be pro posed on the basis of muscle activity. Further-
