Maximal unilateral bite force and endurance times from maximal bite force to the 75% and 50% levels of maximal values were recorded for 13 men and 15 women with bite openings of 10 and 14 mm. Measurements were made both from right and left molar regions and from the incisal region. Bite force values were significantly higher than previously measured in endurance tests by devices with unilateral housings. Men achieved greater bite force than women in the molar region in every trial. The general assumption that women's muscles are superior to those of men in static endurance when both are working at the same percentage of maximal voluntary contraction was not supported by this work for jaw-closing muscles. The endurance times to 75% and 50% levels of maximal bite force were shorter than could be expected from previous reports, and endurance times to the 50% level were even shorter than those reported for muscles of limbs.
记录了13名男性和15名女性在张口度为10毫米和14毫米时的最大单侧咬合力，以及从最大咬合力到最大值的75%和50%水平的耐力时间。测量是从左右磨牙区域和切牙区域进行的。咬合力值显著高于之前使用单侧外壳装置进行的耐力测试中的测量值。在每次试验中，男性在磨牙区域的咬合力都比女性大。这项关于咬肌的研究不支持一般的假设，即在相同最大自主收缩百分比下工作时，女性肌肉在静态耐力方面优于男性。达到最大咬合力75%和50%水平的耐力时间比之前报告的预期要短，而达到50%水平的耐力时间甚至比四肢肌肉的报告时间还要短。
