实验:Apple Watch是心率监测最准确的可穿戴设备

站搜网5月25日消息,在一项比较七种不同健身追踪器数据测量准确性的新研究中,发现苹果手表Apple Watch在测量心率时最准确,击败了Basis Peak,Fitbit Surge,微软手环,Mio Alpha 2,PulseOn和三星Gear S2。总共有60名志愿者参与实验,其中男29人,女31人,每人身上带有多个健身追踪器,需要完成骑自行车,跑步和步行等运动

站搜网5月25日消息,在一项比较七种不同健身追踪器数据测量准确性的新研究中,发现苹果手表Apple Watch在测量心率时最准确,击败了Basis Peak,Fitbit Surge,微软手环,Mio Alpha 2,PulseOn和三星Gear S2。

总共有60名志愿者参与实验,其中男29人,女31人,每人身上带有多个健身追踪器,需要完成骑自行车,跑步和步行等运动。健身追踪器收集的数据会与使用ECG测量的数据进行对比,错误率为5%被认为是可接受的范围内。

在所有活动数据中,苹果手表的心率中位误差最低,为2%(1.2%至2.8%),而三星Gear S2的误差率最高为6.8%(4.6%至9%)。在步行测试期间,Apple Watch在测量心率方面也比竞争产品更准确。

在测量卡路里方面,包括苹果手表在内,没有设备能够准确地确定活动燃烧了多少卡路里。所有设备在不同活动的中位误差率范围为在27.4%(Fitbit Surge)到92.6%(PulseOn)之间。虽然没有设备是准确的,但Apple Watch可以更好的预测能量消耗。

总的来说,研究人员发现,大多数测试的健身追踪器都能够在实验室环境中得到误差范围内可接受的心率数据,但是卡路里的测量在很大程度上是不准确的。
