Real-time digital heart rate (HR) monitoring in sports can provide unique physiological insights into athletic performance. However, most HR monitoring of elite athletes is limited to non-real-time, non-competition settings while utilizing sensors that are cumbersome. The present study was undertaken to test the feasibility of using small, wearable medical-grade sensors, paired with a novel technology system, to capture and process real-time HR data from elite athletes during professional competition.
We examined the performance of the BioStamp nPoint® sensor compared to the Polar chest strap HR sensor in 15 Professional Squash Association (PSA) tournament matches in 2019-2020. Fourteen male professional squash players volunteered for the study (age = 23.8 ± 4.9 years; height = 177.9 ± 7.1 cm; weight = 71 ± 7.0 kg), which was approved by the PSA in accordance with their Code of General Conduct and Ethics. Algorithms developed by Sports Data Labs (SDL; Detroit, MI, USA) used proprietary data collection, transmission, and signal processing protocols to produce HR values in real-time during matches. We calculated the mean and maximum HR from both sensors and used widely accepted measures of agreement to compare their performance.
The system captured 99.8% of HR data across all matches (range 98.3-100%). The BioStamp's mean HR was 170.4 ± 20.3 bpm, while the Polar's mean HR was 169.4 ± 21.7 bpm. Maximum HR ranged from 182 to 202 bpm (Polar) and 185 to 203 bpm (BioStamp). Spearman's correlation coefficient ( ) was 0.986 ( < 0.001), indicating a strong correlation between the 2 devices. The mean difference () in HR was 1.0 bpm, the mean absolute error was 2.2 bpm, and the percent difference was 0.72%, demonstrating high agreement between device measurements.
It is feasible to accurately measure and monitor real-time HR in elite athletes during competition using BioStamp's and SDL's proprietary system. This system facilitates development and understanding of physiological digital biomarkers of athletic performance and physical and psychosocial demands in elite athletic competition.
运动中实时数字心率（HR）监测可为运动表现提供独特的生理见解。然而，大多数精英运动员的心率监测仅限于非实时、非比赛环境，且使用的传感器笨重。本研究旨在测试使用小型可穿戴医疗级传感器与一种新技术系统相结合，在职业比赛期间从精英运动员身上捕获和处理实时心率数据的可行性。
我们在2019 - 2020年的15场职业壁球协会（PSA）锦标赛中，将BioStamp nPoint®传感器与Polar胸带心率传感器的性能进行了比较。14名男性职业壁球运动员自愿参与本研究（年龄 = 23.8 ± 4.9岁；身高 = 177.9 ± 7.1厘米；体重 = 71 ± 7.0千克），该研究经PSA根据其《一般行为和道德准则》批准。体育数据实验室（SDL；美国密歇根州底特律）开发的算法使用专有的数据收集、传输和信号处理协议，在比赛期间实时生成心率值。我们计算了两个传感器的平均心率和最高心率，并使用广泛接受的一致性测量方法来比较它们的性能。
该系统在所有比赛中捕获了99.8%的心率数据（范围为98.3 - 100%）。BioStamp的平均心率为170.4 ± 20.3次/分钟，而Polar的平均心率为169.4 ± 21.7次/分钟。最高心率范围为182至202次/分钟（Polar）和185至203次/分钟（BioStamp）。Spearman相关系数（）为0.986（<0.001），表明这两种设备之间存在强相关性。心率的平均差异（）为1.0次/分钟，平均绝对误差为2.2次/分钟，百分比差异为0.72%，表明设备测量之间具有高度一致性。
使用BioStamp和SDL的专有系统在比赛期间准确测量和监测精英运动员的实时心率是可行的。该系统有助于开发和理解运动表现以及精英运动比赛中的身体和心理社会需求的生理数字生物标志物。
