FABRINI, Sabrina Pinheiro et al. Practices for reducing body mass of judokas in the pre-competitive season. Rev. bras. educ. fís. esporte (Impr.) [online]. 2010, vol.24, n.2, pp. 165-177. ISSN 1807-5509. http://dx.doi.org/10.1590/S1807-55092010000200002.
The aim of this work was to evaluate the procedures adopted for weight loss in periods close to competitions, and emphasize their physiologic effects. One hundred and twenty-five athletes (20 female and 105 male) belonging to the Juvenil, Junior and Senior categories (21.5 ± 8.0 years old) participated in this study. According to the results, 73.6% of the athletes used strategies of weight reduction methods during the pre-competitive periods. The methods used by the athletes were: increasing physical activity level (76.1%), caloric restriction (59.8%), restriction of carbohydrates (32.6%), and restriction of liquids (20.7%). In absolute values, male Judokas presented greater reductions in (p < 0.05) body mass compared to women (4.5 ± 3.5 and 1.7 ± 0.8 kg, respectively). Women started using pre-competition strategies (p < 0.05) to reduc body weight sooner than men (14 ± 6 and 19 ± 7 days, respectively). In conclusion, the most of judokas develop strategies for acute body mass reduction in pre-competitive periods, which may decrease their performance
