Values are mean ± SD (95% CI) with CI in round brackets using a semicolon. Pre: SST after the standardized general warm-up in that period. Δ3′/Δ6′/Δ9′/Δ12′: absolute change (°C) from Pre at 3/6/9/12 min (positive = warmer; negative = cooler). Period: P1, P2 (crossover). Sequence: ICA→VPA or VPA→ICA (order of conditions). Conditions: ICA = isometric conditioning activity (3×5×3 s; total 45 s; 3-min interset rest); VPA— standardized volleyball pre-training activation condition
