<p>&nbsp;</p><p class="resumenyabstract" align="justify">El prop&oacute;sito del presente estudio fue caracterizar el esfuerzo de judo, mediante la cuantificaci&oacute;n de cambios inducidos por un combate sobre aspectos metab&oacute;licos y neuromusculares. En una muestra de 8 judocas masculinos pertenecientes a la Selecci&oacute;n Gallega Senior, se registr&oacute; la frecuencia card&iacute;aca (Fc) durante un enfrentamiento. Antes e inmediatamente despu&eacute;s del combate se midieron lactacidemia, salto con contramovimiento, dinamometr&iacute;a manual y rendimiento isom&eacute;trico en press banca 90&ordm;, remo 90&ordm; y sentadilla 160&ordm;. Fc se situ&oacute; en el 92,65&plusmn;3,26% de la m&aacute;xima (%Fcm&aacute;x.) alcanzando la lactacidemia niveles de 13,75&plusmn;3,09 mmol/L. Descendi&oacute; aproximadamente un 5% el resultado en dinamometr&iacute;a manual. El rendimiento en los ejercicios de remo y press banca disminuy&oacute;, alcanzando significaci&oacute;n estad&iacute;stica en &eacute;ste &uacute;ltimo para el valor pico (PFI) y medio (MFI) (postest 93,93&plusmn;6,20% y 91,60&plusmn;9,47% respecto al pretest para PFI y MFI respectivamente). Se apreciaron diferencias entre las modificaciones del rendimiento isom&eacute;trico del miembro inferior y superior, siendo este &uacute;ltimo menos afectado. <br /><strong>Palabras Clave: </strong>judo, fuerza, lactacidemia, frecuencia card&iacute;aca.</p><br><p class="resumenyabstract" align="justify">The purpose of this study was to characterize the effort in judo, through quantification of changes induced by a fight on neuromuscular and metabolic aspects. In a sample of 8 male judo fighters, members of the Senior Galician Selection (Spain), heart rate (Fc) was recorded during a judo match. Before and immediately after the fight lactate blood concentration, countermovement jump, isometric handgrip dinamometry and performance in isometric bench press 90&ordm;, rowing 90&ordm; and squat 160&ordm; were measured. Fc represented 92.65&plusmn;3.26% of the maximum (%Fcm&aacute;x.) reaching lactate concentration levels of 13.75&plusmn;3.09 mmol/L. Results decreased around 5% in isometric handgrip dinamometry. Performance decreased in bench press and rowing exercises, reaching statistical significance in rowing exercise for peak force (PFI) and average force (MFI) (postest 93.93&plusmn;6.20% and 91.60&plusmn;9.47% of pretest for PFI and MFI respectively). Isometric changes for lower limbs were less marked than for higher limbs. <br /><strong>Key Words:</strong> judo, strength, lactate concentration, heart rate.</p>
