新研究发现苹果观察对心率和步骤准确,但卡路里跟踪不可靠。 New study finds Apple Watch accurate for heart rate and steps but unreliable for calorie tracking.

密西西比大学的一项新研究分析了56项研究,发现苹果监视器在跟踪心率和步骤方面非常准确,平均误差分别为4.43%和8.17%。 A new study from the University of Mississippi analyzing 56 studies found that Apple Watches are highly accurate for tracking heart rate and steps, with average errors of 4.43% and 8.17%, respectively. 然而,该装置的卡路里燃烧估计值不太可靠,误差率为28%。 However, the device's calorie burn estimates are less reliable, with a 28% error rate. 虽然苹果观察的性能随着时间推移而有所改善,但研究人员建议,不应依赖它来进行精确的卡路里跟踪。 While the Apple Watch's performance has improved over time, researchers suggest that it should not be relied upon for precise calorie tracking.
