Propuesta y resultados de una evaluación condicional específica para el entrenamiento de judo: La batería blasco aplicada en judokas españoles.

The conditional assessment becomes a basic element at the Top level Performance, when its focused on specific and relevant measurements. To improve the spectrum of evaluation in Judo, we have developed a battery of six tests with the aim to determine in which conditional capacities show up significantly the best judoists. The study evaluates 53 Spanish national and international level judoists - 24 women (w: -48 to -70 kg) and 29 men (m: -60 to -90 kg) - divided in three groups of level resulting from the championships results and a technicians ranking list. The final sample shows 21 Average, 20 Good and 12 Very Good judoists (13 m and 8 w; 9 m and 11 w, and 7 m and 5 w respectively). The protocol gathers the six tests in three blocks; and the study is based on the implementation of one-way Anova with the level of performance as the independent factor and the results of each test as the dependent factors. 1): RJ45 intervallic (Bosco modified for Judo); and a Progressive Test of Maximum Strength and Power (exercise: "lying pronus Rowing"; charges related to Body Weight) with a linear encoder. 2) Blasco Test. The first part assumes that Judo Specific Stamina (JSS) is basically a Specific RFD (Rate Force Development) and Speed Muscular Endurance within an intervallic structure; the second part evaluates the residual Isometric Strength Endurance (ISE). 3) Anthropometric assessment; resting ISE Test, and a Treadmill VO2max Test (Wasserman). The results of the study indicate that Specific Stamina is the item that determines significantly the judoists performance (p = 0,000 among Very Good and Average, and Good and Average male; p = 0,035 and 0,042 among Very Good and Average, and Good and Average female, respectively); with differences related to gender: maximum levels of Specific RFD muscular endurance in men, with significance in all the explosive factors; while women show high levels of Speed Endurance (although without significance), with no significance in the explosive Factors. Moreover, the study provides a specific test (Test Blasco) able to assess this SS within a global perspective, both quantitative and qualitatively.
