isometric contraction meaning in English
等测度收缩
等长收缩
Examples
- Isometric contraction of skeletal muscle with multiple parameters
多参量的骨骼肌等长收缩初步研究 - Semg dynamics of muscle fatigue induced by maximal voluntary isometric contractions
最大随意收缩诱发肌肉疲劳的表面肌电信号变化 - Relationship between surface electromyographic signal changes and subjective assessment of muscle fatigue during isometric contractions
变化与主观疲劳感之间的关系 - After a maximal response to kc1 was obtained under an initial tension of 2 g , isometric contractions induced by iron or pe were measured , and calculated as percentage of the maximal tension induced by kc1 . the rings with or without endothelium were preconstricted with 10 " 6mol / l of pe and a cumulative concentration - response curve to ach , or sodium nitroprusside ( snp ) , or l - arginine ( l - arg ) was obtained
用10 ~ ( - 6 ) mol lpe预收缩后，加入不同浓度的ach 、硝普钠( snp )或l -精氨酸( l - arg ) ，浙江大学硕士学位论文以各种浓度所致的舒张幅度达到pe所致的收缩幅度的百分比作血管舒张反应的量效曲线。 - Our results suggested the accumulation of ft in muscle was not the only factor that affected " spectrum shift " during muscle fatigue . the decline of the firing rate of motor units , the synchronization of motor units and an inadequate cns drive may be the important mechanisms that attributed to the change of semg signal during isometric contractions
本研究认为肌肉疲劳过程中h ~ +浓度升高不是导致肌电功率谱曲线左移的唯一因素，运动单位放电频率下降、中枢驱动减弱和运动单位活动的有序性或同步化可能是肌肉活动时肌电信号变化的一种重要机制。
