INTRODUCTION: The determination of the exercise intensities of the Judo match can be very useful for coaches and players to optimize training sessions. Thus, the goals of the current ´s study were to determine the exercise intensities of the Judo match (for the male and female divisions) and to define the type of relationship (independency or dependency) between the exercise intensities of the Judo match and the Judo weight divisions. METHODS: Ninety-six (forty-eight males and forty-eight females) national and international level judoists were clustered on six groups considering the official weight divisions: lightweight ([ML]; -60kg, -66kg, -73kg), middleweight ([MM]; -81kg, -90kg) and heavyweight ([MH]; -100kg, +100kg) for males, and lightweight ([FL]; -48kg, -52kg, -57kg), middleweight ([FM]; -63kg, -70kg) and heavyweight ([FH]; -78kg, +78kg) for females. They participated in only one match against an opponent of the same sex and weight division. Matches were conducted following special rules to guarantee that all matches lasted 5 min (Franchini et al., 2013). Players wore an accelerometer that was located on their belly buttons with an adjustable elastic belt. Data obtained from the accelerometers were: Judo match time at different levels of exercise intensity (sedentary, light, moderate, vigorous and very vigorous) in sec. RESULTS: Players of all weight divisions predominantly fought at moderate and vigorous intensities (ML, 184.2±40.1 sec -61.3±13.3%- and 84.3±38.3 sec -28.1±12.8%-; MM, 170.6±32.9 sec -56.9±11%- and 99.2±42.2 sec -33.1±14.1%-; MH, 157.6±33.7 sec -52.5±11.2%- and 105.1±27.5 sec -35±9.1%-; FL, 209.4±46.2 sec -69.8±15.4%- and 50.4±28.7 sec -16.8±9.6%-; FM, 184.1±31.2 sec -61.3±10.4%- and 63.1±28.4 sec -21.1±9.4%; FH, 162.3±19.6 sec -54.1±6.5%- and 107.2±27.9 sec -35.7±9.3%-, moderate and vigorous, respectively). The chi-square test suggested independency between the exercise intensities of the Judo match and the Judo weight divisions (?2=25.62, p=0.1787). CONCLUSION: In their training, judoists of the all weight divisions should predominantly prepare for matches of moderate and vigorous exercise intensities.
