The analyses were performed before (baseline) and after the progressive effort (5 minutes post effort) and during recovery time (about 17 hours after the test). 1 Differences in baseline values among analyzed groups (YYRL1 vs. Beep vs. MT) were assessed using the Kruskal–Wallis analysis of ranks and the median test (pKW, Kruskal–Wallis p values). Significance levels of differences observed between analyzed time points (pre-exercise vs. post-exercise vs. recovery) were assessed using the Friedman’s analysis of variance for repeated measures (pF, Friedman’s ANOVA p values) followed by post-hoc Dunn’s test with Bonferroni correction. Post-hoc p values, A p < 0.05 for baseline vs. post-effort; B p < 0.05 for post-effort vs. recovery; C p < 0.05 for baseline vs. recovery. N, number of participants; Beep, maximal multistage 20 m shuttle run test; MT, efficiency test on mechanical treadmill; YYRL1, YO-YO intermittent recovery test level 1 protocol.
