It has been proposed that rhythmic movements such as locomotion and respiration have a period proportional to body mass(1/4). Mastication basically consists of rhythmic alternation of jaw-closing and jaw-opening movements. We studied the relation between masticatory rhythm and body mass in primates, and masticatory rhythm and mandible morphology.
We measured the chewing cycle duration (CCD), mandibular length, mandible height, mandible width and distance from the condylar process of mandible to the centre of gravity of the mandible. Body mass was quoted from the literature.
The CCD is related to mandible morphology and was found to be proportional to body mass(1/6).
These findings suggest that masticatory rhythm is correlated with body mass and mandibular morphology, and that scaling rate of masticatory rhythm to body mass is slower than for the other rhythms.
有人提出，类似于运动和呼吸等有节奏的运动的周期与体重成比例（1/4）。咀嚼基本上由下颌闭合和张开运动的有节奏的交替组成。我们研究了灵长类动物的咀嚼节律与体重以及咀嚼节律与下颌形态之间的关系。
我们测量了咀嚼周期持续时间（CCD）、下颌长度、下颌高度、下颌宽度以及下颌从髁突到下颌重心的距离。体重数据援引自文献。
CCD 与下颌形态有关，并且与体重成比例（1/6）。
这些发现表明，咀嚼节律与体重和下颌形态有关，而且咀嚼节律与体重的比例比其他节律慢。
