Continuous vertical jump test is a reliable alternative to wingate anaerobic test and isokinetic fatigue tests in evaluation of muscular fatigue resistance in endurance runners

Table 2 Comparison of total work output (TW) measured during the high-intensity isokinetic fatigue test (ISO FAT), during baseline vertical jump test (CVJT_baseline), and following half (CVJT_half) and ultra-marathon (CVJT_ultra) race with TW measured during the wingate anaerobic test (WAnT; 38623 ± 12664 J)

Note. _a comparison to the TW measured during the Wingate anaerobic test (p > 0.05); _b the magnitude of the difference was considered either small (0.2 < g ≤ 0.5), moderate (0.5 < g ≤ 0.8), or large (g > 0.8). _c expressed in percentage of TW measured during WAnT, ICC, intraclass correlation coefficient; CI, confidence interval; LOA, limits of agreement; SEM, standard error of measurement, MDC₉₅, minimum detectable change at the 95% confidence interval
