Abstract

This study sought to assess the validity and reliability of several heart rate (HR) monitors during mountain biking (MTB), compared to the Polar H7® HR monitor, used as the criterion device. Methods: A total of 20 participants completed two MTB trials wearing 6 HR monitors (1 criterion, 5 test devices). HR was recorded on a second-by-second basis for all devices analyzed. After data processing, validity measures were calculated, including 1. Error analysis: mean absolute percentage errors (MAPE), mean absolute error (MAE), and mean error (ME), and 2. Correlation analysis: Lin’s concordance correlation coefficient (CCC) and Pearson’s correlation coefficient ®. Validity was determined for overall HR as well as stratified HR data based on 5 HR zones. Thresholds for validity were set at MAPE0.7. Reliability measures were also determined comparing trial 1 to trial 2 via two statistical tests: 1. Intra-class correlation coefficient (ICC) and 2. Coefficient of variation (CV). The predetermined reliability threshold was set at an ICC of >0.7 and a CV
