The polar verity sense (PVS) is a user-friendly heart rate monitoring tool for field-based research compared to Polar H10. However, its validity in the real world (e.g., school settings) among children and adolescents is yet to be determined. Thirty-nine adolescents (12.2 ± 0.4 years, 25 males) participated in a 6-min resistance-based high-intensity interval training (HIIT) session. Heart rate was simultaneously measured by PVS and Polar H10 (criterion measure). Validation metrics included within-participant correlation, mean absolute error, mean absolute percentage error and Bland-Altman plots. Overall, PVS showed very strong within-participant correlation (r = 0.93, p < .001) with Polar H10. The mean absolute and percentage error was 4 b·min-1 and 2.8%, respectively. The correlation between PVS and Polar H10 decreased (r = 0.84, p < .001) for data above the HIIT intensity threshold (≥80% maximal heart rate) but maintained a strong relationship. The validity of PVS remained similar when accounting for sex, body mass index, waist circumference or cardiorespiratory fitness. PVS demonstrated strong agreement with Polar H10 in monitoring heart rate during HIIT in adolescents within a school setting. Therefore, it is valid to replace traditional inconvenient chest strap heart rate monitors with a practical and ergonomic armband PVS, which could largely enhance the feasibility of HIIT fidelity monitoring.
与 Polar H10 相比，极地心率传感（PVS）是一种便于现场研究使用的心率监测工具。然而，其在儿童和青少年的现实环境（如学校环境）中的有效性尚待确定。39 名青少年（12.2 ± 0.4 岁，25 名男性）参加了一次 6 分钟的基于阻力的高强度间歇训练（HIIT）课程。心率由 PVS 和 Polar H10 同时测量（作为标准测量）。验证指标包括参与者内相关性、平均绝对误差、平均绝对百分比误差和 Bland-Altman 图。总体而言，PVS 与 Polar H10 显示出非常强的参与者内相关性（r = 0.93，p <.001）。平均绝对误差和百分比误差分别为 4 次·分钟-1 和 2.8%。对于高于 HIIT 强度阈值（≥80%最大心率）的数据，PVS 与 Polar H10 之间的相关性下降（r = 0.84，p <.001），但仍保持较强关系。在考虑性别、体重指数、腰围或心肺适能时，PVS 的有效性保持相似。在学校环境中，PVS 在监测青少年 HIIT 期间的心率方面与 Polar H10 显示出高度一致性。因此，用实用且符合人体工程学的臂带式 PVS 取代传统不便的胸带式心率监测器是有效的，这可以大大提高 HIIT 保真度监测的可行性。
