| Popis: | Background: Different methods for heart rate (HR)-determination are used in routine performance diagnostics. Aim of the study was to compare different HR measurement methods during treadmill performance diagnostics.Methods: 76 athletes (28.614.7 years, 38% female) performed a treadmill lactate threshold test. HR during testing was simultaneously assessed by analysis of a 12-lead electrocardiogram (ECG) both automatically (aECG) and manually (mECG) and a heart rate monitor (HRM). ECGs and HRM measurements were analyzed by two diagnosticians and finally, three different HR curves (aECG, mECG, HRM) were generated and compared at different time points.Results: ECG-based HR detection revealed excellent reproducibility and reliability. Concerning HRM/aECG, faulty measurements were detected in 14.5%/36.8% of all athletes. However, constructions of HR/lactate curves were still possible in 84.6%/73.7% of all athletes. HR at different corresponding time points did not differ significantly between mECG and HRM/aECG (intraclass correlation coefficient >0.9/0.8 and coefficient of variation |
