aMagnitude thresholds (for difference in means divided by average SD): <0.20, trivial; 0.20-0.59, small; 0.60-1.19, moderate; 1.20-2.00, large. Asterisks indicate effects clear at the 90% level and likelihood that the true effect is substantial, as follows: *possible, **likely, ***very likely, ****most likely. No asterisks mean that 90% CL overlapped the thresholds for substantiveness (unclear difference).
VO2max --maximal oxygen consumption, vV̇O2max - minimal running speed required to elicit V̇O2max, vinc.t. – peak incremental test speed, HRmax – maximal heart rate, VT1 / VT2 – first / second ventilatory threshold in % of V̇O2max, vVT1 / vVT2 – running speed associated with VT1 / VT2, GXT – graded exercise test, RPE – Borg's rating of perceived exertion, CMJ – countermovement jump height, PE – power endurance (30s Bosco test).
