Relationships Between the Methods for Estimating the Lactate and Ventilatory Thresholds During Prolonged Exercise in Ice-hockey Players The investigation aimed to find similarities and differences between parameter values corresponding to exercise intensity at the anaerobic threshold determined using a 4MmAT method analysing the lactate curve and a method analysing ventilation changes. The VO2, HR, PAT, and LA values at the anaerobic threshold were found to be statistically different at the level of p ≤ 0.001. Parameter values at the anaerobic threshold as found using the 4MmAT method are lower than those provided by the VT method, i.e. 47.13 ± 2.54 and 49.88 ± 2.37 ml×kg−1×min−1 for VO2AT, 161 ± 4.4 and 169 ± 5.1 bp×min−1 for HRAT and 3.16 ± 0.12 and 3.41 ± 0.14 W×kg−1 for PAT, respectively. All parameters recorded for exercise intensity at the AT level were determined to be statistically significantly related. Regardless of the method applied, power parameters at the AT level were found to be very similar, while HR values turned out to be the least similar. Vztahy mezi metodami určování prahových hodnot laktátu a ventilace v průběhu déletrvajících cvičení hráčů ledního hokeje Cílem šetření bylo nalézt podobnosti a rozdíly hodnot ukazatelů odpovídajících intenzitě cvičení na úrovni anaerobního prahu stanovené pomocí 4MmAT metody analyzující laktátovou křivku a metody analyzující změny ventilace. Statisticky významné rozdíly (na úrovni p ≤ 0.001) byly nalezeny u hodnot VO2, SF, výkonu a laktátu na úrovni anaerobního prahu. Hodnoty zjištěné metodou 4MmAT byly nižší než hodnoty zjištěné měřením změn ventilace, konkrétně 47.13 ± 2.54 a 49.88 ± 2.37 ml×kg−1×min−1 u VO2, 161 ± 4.4 a 169 ± 5.1 bp×min−1 u SF a 3.16 ± 0.12 a 3.41 ± 0.14 W×kg−1 u výkonu. Souvislosti mezi všemi parametry cvičení na úrovni anaerobního prahu byly shledány statisticky významnými. Zjištěné parametry výkonu na úrovni anaerobního prahu byly podobné bez ohledu na použité metody, přičemž hodnoty SF byly velmi podobné.
