A within-group study was conducted with 68 healthy adults (21 women). Participants completed two laboratory sessions using both monitors in random order. HR values were collected at rest, during the Ellestad maximal treadmill stress testing protocol, and in active recovery. Relative reliability was assessed using the two-way random effects intraclass correlation coefficient for agreement (ICC(2,1)). Absolute reliability was assessed using typical error (TE, in bpm and %), coefficient of variation (CV, %), and minimal detectable change (MDC, in bpm and %).
