Elliot, CA, Hamlin, MJ, and Lizamore, CA. Validity and reliability of the Hexoskin wearable biometric vest during maximal aerobic power testing in elite cyclists. J Strength Cond Res 33(5): 1437-1444, 2019-The purpose of this study was to investigate the validity and reliability of the Hexoskin vest for measuring respiration and heart rate (HR) in elite cyclists during a progressive test to exhaustion. Ten male elite cyclists (age 18-52 yrs, height 179.3 ± 6.0 cm, body mass 73.2 ± 9.1 kg, V[Combining Dot Above]O2max 60.7 ± 7.8 ml·kg·min, mean ± SD) conducted a maximal aerobic cycle ergometer test using a ramped protocol (starting at 100 W with 25 W increments each min to failure) during 2 separate occasions over a 3-4-day period. Compared with the criterion measure (MetaMax 3B) the Hexoskin vest showed mainly small typical errors (1.3-6.2%) for HR and breathing frequency (f), but larger typical errors (9.5-19.6%) for minute ventilation (V[Combining Dot Above]E) during the progressive test to exhaustion. The typical error indicating the reliability of the Hexoskin vest at moderate-intensity exercise between tests was small for HR (2.6-2.9%) and f (2.5-3.2%) but slightly larger for V[Combining Dot Above]E (5.3-7.9%). We conclude that the Hexoskin vest is sufficiently valid and reliable for measurements of HR and f in elite athletes during high-intensity cycling but the calculated V[Combining Dot Above]E value by the Hexoskin vest produced during such exercise should be used with caution because of the lower validity and reliability of this variable.
加利福尼亚州埃利奥特、迈克尔·哈姆林、加利福尼亚州利扎莫尔。在精英自行车手最大有氧能力测试中，Hexoskin 可穿戴生物特征背心的有效性和可靠性。J 力量与体能研究 33(5):1437-1444，2019 年-本研究的目的是探讨 Hexoskin 背心在精英自行车手进行递增至力竭的测试过程中测量呼吸和心率（HR）的有效性和可靠性。10 名男性精英自行车手（年龄 18-52 岁，身高 179.3±6.0cm，体重 73.2±9.1kg，V[组合点上方]O2max 60.7±7.8ml·kg·min，平均值±标准差）在 3-4 天的时间内，分两次使用斜坡方案（从 100W 开始，每增加 25W 递增到失败）进行最大有氧循环测功仪测试。与标准测量（MetaMax 3B）相比，Hexoskin 背心在递增至力竭的测试过程中，HR 和呼吸频率（f）的典型误差主要较小（1.3-6.2%），但分钟通气量（V[组合点上方]E）的典型误差较大（9.5-19.6%）。在两次测试之间，中等强度运动时，Hexoskin 背心的可靠性的典型误差对 HR（2.6-2.9%）和 f（2.5-3.2%）较小，但对 V[组合点上方]E（5.3-7.9%）稍大。我们得出结论，在高强度自行车运动中，Hexoskin 背心对精英运动员的 HR 和 f 测量具有足够的有效性和可靠性，但在这种运动中，Hexoskin 背心计算出的 V[组合点上方]E 值应谨慎使用，因为该变量的有效性和可靠性较低。
