Abstract：
Technological development has boosted the use of multi-sensor devices to monitor athletes\' performance, but the location and connectivity between devices have been shown to affect data reliability. This preliminary study aimed to determine whether the placement of a multi-sensor device (WIMU PROTM) could affect the heart rate signal reception (GARMINTM chest strap) and, therefore, data accuracy. Thirty-two physical education students (20 men and 12 women) performed 20 min of exercise in a cycle ergometer based on the warm-up of the Function Threshold Power 20 test in laboratory conditions, carrying two WIMU PROTM devices (Back: inter-scapula; Bicycle: bicycle\'s handlebar-20 cm from the chest) and two GARMINTM chest straps. A one-dimensional statistical parametric mapping test found full agreement between the two situations (inter-scapula vs. bicycle\'s handlebar). Excellent intra-class correlation values were obtained during the warm-up (ICC = 0.99, [1.00-1.00], p < 0.001), the time trial test (ICC = 0.99, [1.00-1.00], p < 0.001) and the cool-down (ICC = 0.99, [1.00-1.00], p < 0.001). The Bland-Altman plots confirmed the total agreement with a bias value of 0.00 ± 0.1 bpm. The interscapular back placement of the WIMU PROTM device does not affect heart rate measurement accuracy with a GARMINTM chest strap during cycling exercise in laboratory conditions.
摘要：
技术发展促进了多传感器设备的使用，以监测运动员的表现，但是设备之间的位置和连接已经被证明会影响数据的可靠性。这项初步研究旨在确定多传感器设备(WIMUPROTM)的放置是否会影响心率信号接收(GARMINTM胸带)，因此,数据准确性。根据实验室条件下功能阈值功率20测试的预热，32名体育学生（20名男性和12名女性）在自行车测功机中进行了20分钟的运动，携带两个WIMUPROTM设备（背部：肩胛骨间；自行车：自行车车把-距离胸部20厘米）和两个GARMINTM胸带。一维统计参数映射检验发现两种情况之间完全一致（肩胛骨与自行车车把)。在热身期间获得了优异的类内相关值(ICC=0.99，[1.00-1.00]，p<0.001)，时间试验测试(ICC=0.99，[1.00-1.00]，p<0.001)和冷却(ICC=0.99，[1.00-1.00]，p<0.001)。Bland-Altman地块确认了完全一致，偏差值为0.00±0.1bpm。在实验室条件下进行自行车运动期间，使用GARMINTM胸带，WIMUPROTM设备的肩胛骨间背部放置不会影响心率测量精度。
