Energy System Contributions to the Special Judo Fitness Test

Purpose:This study investigated the energy system contributions of judo athletes to the Special Judo Fitness Test (SJFT). Methods: Fourteen male judo athletes performed the SJFT, which comprised three periods of judo activity (A = 15 s, B and C = 30 s) interspersed with 10 s rest intervals. During this test, one athlete threw two others positioned 6 m from each other using the ippon-seoi-nage technique. The fractions of the aerobic, anaerobic alactic and anaerobic lactic systems were calculated based on oxygen uptake, the fast component of excess postexercise oxygen uptake, and changes in net blood lactate, respectively. The contribution of the three energy systems was compared using a repeated measures analysis of variance and Bonferroni’s multiple comparisons test. Compound symmetry, or sphericity, was determined by Mauchly’s test. A level of significance of 5% (P < .05) was adopted in all analyses. Results: The alactic energy system presented a higher (F = 20.9; P < .001; power observed = 1.0) contribution (86.8 ± 23.6 kJ; 42.3 ± 5.9%) during the test when compared with both aerobic (57.1 ± 11.3 kJ; 28.2 ± 2.9%) and lactic (58.9 ± 12.1 kJ; 29.5 ± 6.2%) energy systems (P < .001 for both comparisons). Conclusions: The higher alactic contribution seems to be a consequence of the high-intensity efforts performed during the test, and its intermittent nature. Thus, when using the SJFT, coaches are evaluating mainly their athletes’ anaerobic alactic system, which can be considered to be the most predominant system contributing to the actions (techniques) performed in the match.

  1. Poxa, parabéns cara!
    Vc merece todo o sucesso conquistável.
    Responsável, profissional, sério, dedicado e "veste o judogi". Parabéns mesmo. (Mande-me o artigo?)
    Ah, ano que vem completaremos 10 anos de relacionamento "ao vivo". Copa Rio de 2002. haha.
    Festinha!

  2. Fala Fabrício, valeu.
    Às vezes bem, às vezes nem tanto, vou tocando as atividades. Queria ter um tempo para respirar e contemplar um pouco as coisas feitas.
    Talvez vestir mais o judogi também seja uma meta (100 vestimentos no ano não ia ser nada mal, rs).
    Precisamos ver a data da Copa Rio para fazermos uma celebração, quem sabe em um outro congresso de lutas se as datas coincidirem : )
    Por enquanto só tenho a prova do artigo (tabela e figura fora do texto), mas lhe envio assim que conseguir o pdf oficial.
    Abração
