The Bioharness(™) monitoring system may provide physiological information on human performance but the reliability of this data is fundamental for confidence in the equipment being used. The objective of this study was to assess the reliability of each of the 5 Bioharness(™) variables using a treadmill based protocol. 10 healthy males participated. A between and within subject design to assess the reliability of Heart rate (HR), Breathing Frequency (BF), Accelerometry (ACC) and Infra-red skin temperature (ST) was completed via a repeated, discontinuous, incremental treadmill protocol. Posture (P) was assessed by a tilt table, moved through 160°. Between subject data reported low Coefficient of Variation (CV) and strong correlations(r) for ACC and P (CV< 7.6; r = 0.99, p < 0.01). In contrast, HR and BF (CV19.4; r0.70, p < 0.01) and ST (CV 3.7; r = 0.61, p < 0.01), present more variable data. Intra and inter device data presented strong relationships (r > 0.89, p < 0.01) and low CV (<10.1) for HR, ACC, P and ST. BF produced weaker relationships (r < 0.72) and higher CV (<17.4). In comparison to the other variables BF variable consistently presents less reliability. Global results suggest that the Bioharness(™) is a reliable multivariable monitoring device during laboratory testing within the limits presented. Key pointsHeart rate and breathing frequency data increased in variance at higher velocities (i.e. ≥ 10 km.h(-1))In comparison to the between subject testing, the intra and inter reliability presented good reliability in data suggesting placement or position of device relative to performer could be important for data collectionUnderstanding a devices variability in measurement is important before it can be used within an exercise testing or monitoring setting.
Bioharness(™)监测系统可以提供人体性能的生理信息，但该设备数据的可靠性对于使用者对设备的信心至关重要。本研究的目的是使用基于跑步机的方案评估每个 Bioharness(™)变量的可靠性。10 名健康男性参与了这项研究。采用了一种基于个体间和个体内设计的方法，通过重复、不连续、递增的跑步机方案来评估心率(HR)、呼吸频率(BF)、加速度计(ACC)和红外皮肤温度(ST)的可靠性。通过倾斜台评估姿势(P)，倾斜台移动 160°。个体间数据报告了低变异系数(CV)和强相关性(r)，用于 ACC 和 P (CV< 7.6; r = 0.99, p < 0.01)。相比之下，HR 和 BF (CV19.4; r0.70, p < 0.01)和 ST (CV 3.7; r = 0.61, p < 0.01)则呈现出更具变异性的数据。设备内和设备间数据呈现出强关系(r > 0.89, p < 0.01)和低 CV(<10.1)，用于 HR、ACC、P 和 ST。BF 产生的关系较弱(r < 0.72)和较高的 CV(<17.4)。与其他变量相比，BF 变量的可靠性始终较低。总体结果表明，在实验室测试中，Bioharness(™)是一种可靠的多变量监测设备，在呈现的限制范围内。关键点心率和呼吸频率数据在更高速度(即≥10km.h(-1))时增加了变异性与个体间测试相比，设备内和设备间的可靠性数据表明，设备相对于运动员的放置或位置对于数据收集可能很重要。在将设备用于运动测试或监测环境之前，了解设备测量的变异性非常重要。
