Las asimetrías en la altura de salto durante el cmjunilateral no están relacionadas con las asimetrías de impulso durante el cmj bilateral
This study aims to explore the relationship between unilaterally produced countermovement jump height asymmetries (CMJ) and bilateral CMJ forceproduction asymmetries, and to elucidate the rates of agreement between the self-selected leg and the dominant leg.

| Sumario: | This study aims to explore the relationship between unilaterally produced countermovement jump height asymmetries (CMJ) and bilateral CMJ forceproduction asymmetries, and to elucidate the rates of agreement between the self-selected leg and the dominant leg. Twenty-three senior basketball players performed eight unilateral CMJs (four with each leg) and four bilateral CMJs in a single session. Momentum during the bilateral CMJ and jump height during the unilateral CMJ were recorded. Small correlations were observed between differences in unilateral CMJ height and asymmetries between limbs in bilateral CMJ impulse (r = -0.104). The self-selected declared leg revealed higher performance in 7 out of 23 participants (Kappa = -0.20) for unilateral CMJ height, 7 out of 23 participants (Kappa = -0.11) for bilateral CMJ impulse, 6 out of 23 participants (Kappa = -0.36). These results show that the asymmetries detected during bilateral CMJs cannot be extrapolated to unilateral CMJs, and that the preferred leg generally contributes less to force production than the non-preferred leg. |
