Table 4 The agreement between heart rate (HR), power (P) and speed (v) from ‘lower’ ventilatory threshold (VTlow), ‘lower’ lactate threshold (LTlow) and ‘lower’ heart rate variability threshold (HRVTlow) is displayed using bias with 90% confidence intervals (90% CI) and lower and upper limits of agreements (LLoA/ULoA); N, number of participants; n, number of studies; n.a., no data available
