A variety of wearable technology devices report heart rate. Heart rate sensing smart bras are manufactured for females who participate in activity, however accuracy has not been determined. The purpose was to determine the validity of heart rate measures in three commercially available sports bras during walking and running. Twenty-four healthy females completed bouts of treadmill exercise. The Adidas Smart sports bra, Berlei sports bra, and Sensoria Fitness biometric sports bra were tested. Participant perception of each garment was obtained immediately after the participant divested the sports bra. The Adidas Smart sports bra was valid only during rest (Intraclass correlation Coefficient [ICC] = 0.79, mean absolute percentage error [MAPE] = 4.5%, Limits of Agreement [LoA]=-8 to 8). The Berlei sports bra was valid across all conditions (ICC = 0.99, MAPE = 0.66%, LoA = -19 to 19), and the Sensoria biometric bra was valid during rest and walking (ICC = 0.96, MAPE = 1.9%, LoA = -15 to 12). Perception of the smart sports bras was higher for the Adidas Smart sports bra and Sensoria Fitness sports bra, and lower for the Berlei sports bra. Sports bra manufacturers designing wearable technology garments must consider the ability of returning accurate biometric data while providing necessary function and comfort to females engaging in physical activity.
各种可穿戴技术设备都可以报告心率。为参加运动的女性制造了心率感应智能文胸，但准确性尚未确定。本研究的目的是确定三种市售运动文胸在步行和跑步时测量心率的有效性。24 名健康女性完成了跑步机运动。测试了阿迪达斯智能运动文胸、贝莉运动文胸和 Sensoria Fitness 生物识别运动文胸。参与者在脱下运动文胸后立即获得对每种文胸的感知。阿迪达斯智能运动文胸仅在休息时有效（组内相关系数 [ICC] = 0.79，平均绝对百分比误差 [MAPE] = 4.5%，容许区间 [LoA] = -8 到 8）。贝莉运动文胸在所有条件下均有效（ICC = 0.99，MAPE = 0.66%，LoA = -19 到 19），Sensoria 生物识别文胸在休息和步行时有效（ICC = 0.96，MAPE = 1.9%，LoA = -15 到 12）。对阿迪达斯智能运动文胸和 Sensoria Fitness 运动文胸的感知较高，而对贝莉运动文胸的感知较低。设计可穿戴技术服装的运动文胸制造商必须考虑在为进行体育活动的女性提供必要的功能和舒适度的同时，能够返回准确的生物识别数据的能力。
