Resum<\/h2>\n\n\n

La potenciaci\u00f3 posttet\u00e0nica (PPT) va ser indu\u00efda mitjan\u00e7ant l\u2019electroestimulador Compex Sport 3 sobre el tr\u00edceps braquial de 9 jugadors d\u2019handbol de nivell competitiu mitj\u00e0. A trav\u00e9s d\u2019un disseny intrasubjecte o de mesures repetides, es va avaluar la magnitud de la PPT en 5 moments preestablerts (5 s, 30 s, 60 s, 180 s i 300 s) despr\u00e9s del cessament de l\u2019estimulaci\u00f3 el\u00e8ctrica percut\u00e0nia (EEP). La magnitud de la PPT es va quantificar sobre el gest d\u2019\u201cextensions de tr\u00edceps ajaguts\u201d i mitjan\u00e7ant l\u2019\u00fas del dinam\u00f2metre Isocontrol Din\u00e0mic 3.0. Aquest dinam\u00f2metre va mesurar els descriptors de l\u2019efici\u00e8ncia mec\u00e0nica del gest seleccionat: pot\u00e8ncia m\u00e0xima (Pm\u00e0x) i el temps necessari per assolir-la (Tpm\u00e0x). Es va observar que la Pm\u00e0x no va augmentar de forma significativa en l\u2019estat \u201cpotenciat\u201d encara que es van observar indicis de significaci\u00f3 (P<\/em> = 0.057). Per contra, el Tpm\u00e0x va decr\u00e9ixer de forma significativa durant l\u2019\u201cestat potenciat\u201d. A m\u00e9s a m\u00e9s, hi va haver una difer\u00e8ncia significativa (P<\/em><0.05) entre el valor del Tpm\u00e0x en estat \u201cno potenciat\u201d (P0) i el valor del Tpm\u00e0x en estat \u201cpotenciat\u201d en els moments T1, T4 i T5. Les dades indiquen que la PPT va provocar una millora en l\u2019efici\u00e8ncia mec\u00e0nica del gest realitzat.<\/p>\n\n
