摘要

在动态活动期间收集的生物阻抗测量结果与静态条件相比，由于骨骼肌的收缩和松弛而发生变化。了解这些影响将是在自由生活中收集这类数据的研究的重要考虑因素。在这项初步试验中，收集了单个参与者在5种步行活动(如跑步机步行和爬楼梯)中增加强度的128 kHz膝关节组织阻力。平均和最大阻力随着活动的增加而增加，两个局部组织部位的最高强度跑步机行走(与最低强度相比)的平均阻力分别为1.14 Ω(+1.80%)和2.03 Ω(+6.48%)。

Bioimpedance Alterations of Knee Site Tissues During Dynamic Activity of Varying Intensity

Bioimpedance measurements collected during dynamic activities have alterations compared to static conditions as a result of contraction and relaxation of skeletal muscle. Understanding these effects will be an important consideration for studies collecting this type of data during free-living. In this preliminary trial, 128 kHz knee tissue resistance was collected during 5 walking activities (e.g. treadmill walking and stair climbing) of increasing intensity from a single participant. Mean and maximum resistances were observed to increase with increasing activity, with 1.14 Ω (+1.80%) and 2.03 Ω (+6.48%) mean increases for the highest intensity treadmill walking (compared to the lowest) for the two localized tissue sites, respectively.
