Summary: | <p class="tabulado" align="justify">The knowledge of the efficiency creatine supplements for the improvement of the performanceis the main motive that it has carried us to accomplish this study. There is a huge controversy in this regard. To prove its efficiency have been used N = 10 (20 &plusmn; 2y) (82Kg.&plusmn; 5Kg.) trained subjects, Team Handbal players (1st National Division). The protocol has been the following: They have been divided the subjects in two groups G1 = 5 and G2= 5 in a random way. To the G1 have been administered 4 x 5 g per day of creatine monohydratate (CRH<sub>2</sub>O) during five days. To the G2 (control group) has been administered glucose. A pretest and a posttest were done after ending the feed. In the tests were controlled the following parameters: SJ and CMJ in a platform of pressure and the corporal weight in kgs. Al the subjects accomplished the same training (6 days of training: 3 of them destined to improve strength). Once completed t <em>Student</em> for independent samples, the results did not show meaningful improvements in the variables analyzed. These results demonstrate that an increase in the capacity of the fosfogenolitic route by exogenous way it is not possible in explosive movements in Team handbal players.<br /> KEY WORDS: Handbal, Supplements Creatine, Training, Explosive Power.</p><br><p align="center">&nbsp;</p><p class="tabulado" align="justify">El conocimiento de la efectividad de los suplementos de creatina para la mejora del rendimiento es el principal motivo que nos ha llevado a realizar este estudio. La controversia existente al respecto es grande. Para comprobar su eficacia se han utilizado N = 10 (20 &plusmn; 2 a.) (82 Kg. &plusmn; 5 kgr.) sujetos entrenados, jugadores de balonmano (1&ordf; Divisi&oacute;n Nacional). El protocolo seg uido ha sido el siguiente: Se han dividido los sujetos en dos grupos G1 = 5 y G2= 5 de forma aleatoria. Al G1 se le han administrado 4 x 5 g./d&iacute;a de creatina monohidratada (CRH<sub>2</sub>0) durante cinco d&iacute;as. Al G2 o grupo control (placebo) se le ha administrado glucosa. A todos los sujetos se le realiz&oacute; un pretest y un postest, dos d&iacute;as despu&eacute;s de finalizar las ingestas. En los tests se controlaron los siguientes par&aacute;metros: SJ y CMJ en una alfombrilla de presi&oacute;n y el peso corporal en kg. Durante el periodo comprendido entre los dos test todos los sujetos realizaron el mismo entrenamiento (6 d&iacute;as de entrenamiento: 3 de ellos destinados al trabajo de fuerza). Dicho periodo coincidi&oacute;, de forma intencionada con un microciclo de choque (McCH) dentro de un bloque de fuerza. Una vez realizada <em>t Student</em> para muestras independientes, los resultados no mostraron mejoras significativas en ninguna de las variables analizadas. Estos resultados demuestran que un aumento de la capacidad de la v&iacute;a fosfogenol&iacute;tica por v&iacute;a ex&oacute;gena, durante un McCH, no mejora el rendimiento; en trabajos explosivos con jugadores de balonmano<br /> PALABRAS CLAVE: Balonmano, Suplemento De Cretatina, Fuerza Explosiva, Entrenamiento</p> |
