Table 2 Shows parameters of performance and heart rates in means ± standard deviation. LTs calculated via method by Mader and Dickhuth and AT assessed via dT°. HR heart rate, bpm beats per minute, PO power output, Watt, LT lactate threshold, AT anaerobic threshold. Maximal expected heart rate calculated using the formula HRmax(expected)(bpm) = 208-(age x 0.7)

From: Estimation of anaerobic threshold by cardiac repolarization instability: a prospective validation study
