• Resumen

  • The study aimed to compare the physical fitness of children who train Karate in the region of Joinville, Santa Catarina. The study population consisted of ten children aged eight to 14 who participated in Karate training, 40% of whom were female. The physical fitness variables were: Body Mass Index and Body Adiposity Index; Upper Limb Strength, Lower Limb Strength, Flexibility and Localized Muscular Resistance. Student's t-test was used to compare between pre and post-test, considering p < .05 as significant. Significant differences were found only for Lower Limb Strength (p = .03; d = -0.56) and Localized Muscular Resistance (p = .01; d = -0.54), showing improvement in jumping and abdominal resistance. Although not significant, there was a decrease in body composition in the post-evaluation. In all physical tests there was an increase in the average, revealing that the children presented good performance in jumping and abdominal resistance.
