Zephyr Biotechnology（TM）在2个运动方案中与实验室代谢推车（Vmax）或先前验证的便携式代谢系统（K4 b（2））一起进行测试，以确定心率（HR）和呼吸率（RR）测量的准确性。在一个方案中，在分级运动期间，使用Biofilm和Vmax测量HR和RR，直至（V）超过dot 0（2 max）（n = 12）。在另一个方案中，在热环境（30摄氏度，50%相对湿度）中持续运动（30%和50%（V），dotO（2 max）各20分钟）期间使用BH和K4 b（2）测量HR和RR（n = 6）。在分级运动期间，从生物统计学获得的HR而非RR与基线时的Vmax相比更高，并且比dotO（2 max）高30%（V）（p < 0.05），但在其他阶段没有显示出显著差异，HR（r = 0.87-0.96）和RR（r = 0.90-0.99，比dotO（2 max）高30%（V））两者的相关系数都很高。在高温条件下运动时，BioChloride和K4 b（2）系统之间无显著差异。HR的方法间相关系数较低，但RR的方法间相关系数为中度至高度（0.49-0.99）。总之，在分级运动和高温下持续运动期间，在（V）超过dotO（2）的宽范围内，生物等效性与Vmax和K4 b（2）相当。
The Zephyr BioHarness (TM) was tested to determine the accuracy of heart rate (HR) and respiratory rate (RR) measurements during 2 exercise protocols in conjunction with either a laboratory metabolic cart (Vmax) or a previously validated portable metabolic system (K4b(2)). In one protocol, HR and RR were measured using the BioHarness and Vmax during a graded exercise up to (V)over dotO(2max) (n = 12). In another protocol, HR and RR were measured using the BH and K4b(2) during sustained exercise (30% and 50% (V)over dotO(2max) for 20 min each) in a hot environment (30 degrees C, 50% relative humidity) (n = 6). During the graded exercise, HR but not RR, obtained from the BioHarness was higher compared to the Vmax at baseline and 30% (V)over dotO(2max) (p < 0.05), but showed no significant difference at other stages with high correlation coefficients for both HR (r = 0.87-0.96) and RR (r = 0.90-0.99 above 30% (V)over dotO(2max)). During the exercise in the heat, there were no significant differences between the BioHarness and K4b(2) system. Correlation coefficients between the methods were low for HR but moderately to highly correlated (0.49-0.99) for RR. In conclusion, the BioHarness is comparable to Vmax and K4b(2) over a wide range of (V)over dotO(2) during graded exercise and sustained exercise in the heat.
