Biomechanical hypotheses have been developed to suggest that both body size and body proportions should cause predictable changes in the locomotion of quadrupedal animals. These suggestions have been used to reconstruct locomotor modes of fossil primates. However, these hypotheses have not been adequately tested experimentally. Using a high-speed 3D motion analysis system in conjuction with a force platform, this study will quantify the locomotor patterns and mechanics of a closely related group of Old World monkeys that habitually move quadrupedally on the ground (vervets, patas monkeys, baboons, pig-tailed macaques). The primary goal is to measure the effects of both body size and body proportions on locomotor performance variables. Three different types of comparisons will be made: intraspecific comparisons between males and females of each species since they differ in body size but have similar body proportions; narrow interspecific comparisons between individuals that have similar body mass, but differ in body proportions; and broad interspecific comparisons across the entire sample. These data will be useful for evaluating the mechanical hypotheses that relate body size and body proportions to locomotion. In addition, experimentally established relationships between locomotor behavior and morphology will increase the level of confidence that is placed in the functional interpretations of the locomotor morphology of fossil primates.

生物力学假说已经发展到表明，身体大小和身体比例应该引起可预测的变化，在运动的四足动物。这些建议已被用于重建化石灵长类动物的运动模式。然而，这些假设还没有得到充分的实验验证。使用高速3D运动分析系统结合力平台，本研究将量化一组密切相关的旧世界猴子的运动模式和力学，这些猴子习惯于在地面上四足移动（长尾猴，pata猴，狒狒，猪尾猕猴）。 主要目标是测量身体大小和身体比例对运动性能变量的影响。将进行三种不同类型的比较：每个物种的雄性和雌性之间的种内比较，因为它们的身体大小不同，但身体比例相似;个体之间的狭义种间比较，具有相似的身体质量，但身体比例不同;以及整个样本的广泛种间比较。这些数据将是有用的，用于评估与身体大小和身体比例的运动力学假设。此外，实验建立的运动行为和形态之间的关系，将增加的信心水平，放置在化石灵长类动物的运动形态的功能解释。
