ZEPHYR(TM)BioHarness(TM)(ZEPHYR技术公司，新西兰奥克兰)是一种无线生理监测系统，能够不引人注意地测量呼吸频率。然而，BioHarness(TM)在一定强度范围内准确和可重复地确定呼吸频率的能力目前尚不清楚。这项研究的目的是确定BioHarness(TM)测量呼吸频率的可靠性和有效性。12名体力活动的参与者在两个不同的场合参加了实验室，以进行意志性疲惫的递增跑步机测试。在两个试验期间，使用Metamax 3b在线气体分析系统(德国莱比锡Cortex)和BioHarness(TM)连续同时测量呼吸频率(br.min(-1))。Metamax 3b和BioHarness(TM)测量的平均呼吸频率在大多数速度下没有统计学差异(p<；0.05)，除了跑步机峰值速度的70%(p=.039)。平均绝对差值很小(2~3br.min(-1)；典型误差=4.4%~8.7%)。对于BioHarness(TM)，呼吸率测试1与测试2比较的典型误差范围为1.4到2.8 br.min(-1)(典型误差%=4.3-7.3)。在呼吸断裂点的绝对呼吸频率、呼吸速度和最大呼吸频率的百分比方面，不同装置之间没有显著差异(p>；0.05)。BioHarness(TM)是一种有效和可靠的设备，可以在不同强度的运动中确定呼吸频率和呼吸断点。
The Zephyr (TM) BioHarness (TM) (Zephyr Technology, Auckland, New Zealand) is a wireless physiological monitoring system that has the ability to measure respiratory rate unobtrusively. However, the ability of the BioHarness (TM) to accurately and reproducibly determine respiratory rate across a range of intensities is currently unknown. The aim of this study was to determine the reliability and validity of the BioHarness (TM) to measure respiratory rate. Twelve physically active participants attended the laboratory on two separate occasions to perform an incremental treadmill test to volitional exhaustion. Respiratory rate (br.min(-1)) was measured continuously and simultaneously during both trials using both a Metamax 3b online gas-analysis system (Cortex, Leipzig, Germany) and the BioHarness (TM). The mean respiratory rate measured by the Metamax 3b and BioHarness (TM) did not differ statistically (p < .05) for most speeds, except for 70% of peak treadmill speed (p = .039). Mean absolute differences were small (2 to 3 br.min(-1); typical error = 4.4%-8.7%). The typical errors for the test 1 versus the test 2 comparisons for respiratory rate ranged from 1.4 to 2.8 br.min(-1) (typical error % = 4.3-7.3) for the BioHarness (TM). There were no significant differences between devices for the absolute respiratory rate, speed, and percent of respiratory rate maximum at the respiratory breakpoint (p > .05). The BioHarness (TM) is a valid and reliable device for determining respiratory rate and the respiratory breakpoint during exercise of varying intensity.
