运动速度与肌肉质量（决定力量和步幅率）、肢体长度（步幅率和距离）和躯干横向压缩（力量和步幅距离）相关。为了描述无尾两栖动物的运动-形态计量学关系，我们研究了黑斑蛙（Rana nigromaculata）、黑斑蛙（R. rugosa、东方铃蟾（Bombina orientalis）、菲氏Eleuthrodectilus fitzingeri、E. diastema，蟾蜍typhonius，Colostethus flotator和泡状酸浆虫。最快的跳跃者E。fitzingeri（3.41 in s（-1））的速度比最慢的B快2.49倍。Typhonius。起跳速度与大腿肌肉质量/体质量、后肢长度/口鼻排气口长度（HL/SVL）相关性良好，与髂间宽度/SVL相关性较差。HL/SVL是最佳的形态学预测因子（speed = -3.28 +3.916HL/SVL，r=0.968，P
Locomotory speed correlates with muscle mass (determining force and stride rate), limb length (stride rate and distance), and laterally compressed body trunk (force and stride distance). To delineate generalization of the locomotory-morphometric relationships specifically in anuran amphibians, we investigated take-off speed and the three morphological variables from seven species, Rana nigromaculata, R. rugosa, and Bombina orientalis, Eleuthrodectilus fitzingeri, E. diastema, Bufo typhonius, Colostethus flotator and Physalaemus pustulosus. The fastest jumper E. fitzingeri (3.41 in s(-1)) showed 2.49-fold greater speed than the slowest B. typhonius. Take-off speed correlated well with both thigh muscle mass relative to body mass and hindlimb length relative to snout-vent length (HL/SVL), but poorly correlated with the inter-ilial width relative to SVL. The best morphological predictor was HL/SVL (speed = -3.28+3.916 HL/SVL, r=0.968, P
