The table lists only statistically significant effects (α = 0.05); entries report F-values with degrees of freedom, p-values, and partial eta squared (ηp2). JH:jump height (cm); PP: relative peak power (W·kg-1); CT: contraction time (ms); SST: skin surface temperature (°C); Myoton Frequency: natural oscillation frequency (Hz); Myoton Decrement: logarithmic decrement (dimensionless); P1/P2: crossover periods 1/2; Sequence: order of conditions; ICA: isometric conditioning activity; VPA: standardized volleyball pre-training activation condition without ICA. |
