CMJa - counter movement jump with arm swing; P_peak – peak power; P_mean – mean power; F_peak – peak force; V_peak – peak velocity; T_con - duration of the concentric jump phase; Δh_ecc - maximum lowering of the center of mass during the eccentric jump phase.

< > - lower/higher; ≤ ≥ - equal with first and lower/higher than others; = equal. Statistically significant at the level p = 0.05.
