abstract="PURPOSE: To compare bone mineral density gains in adolescents of both genders stratified according to different martial art styles in a 9-month follow-up study. <br><br>METHODS: The longitudinal study consisted of 29 adolescents of both genders and age between 11 and 17 years stratified into control group ([CG] not engaged in any sport) and 50 fighters (Kung-fu / karate-KF / KT, n = 29; Judo, n = 21). All 79 subjects underwent anthropometric measures (weight, height, leg length and height set), dual energy x-ray absorptiometry (Bone Mineral Density [BMD], in g/cm(2)) at two moments, baseline and nine months later. Maturity offset (age at peak height velocity), lean soft tissue, chronological age and resistance training were treated as covariates. <br><br>RESULTS: Male judoists presented higher gains in BMD-spine (0.098 g/cm(2) [95%CI= 0.068 to 0.128]) than CG (0.040 g/cm(2) [95%CI= 0.011 to 0.069]) (post-hoc test with p-value= 0.030). There was no effect of martial art on BMD gains among girls. Independently of gender, in all multivariate models lean soft tissue constituted the most relevant covariate. <br><br>CONCLUSIONS: Judo practice in adolescents affected the bone accrual significantly after 9-month follow-up compared to controls, mainly in boys.<p /> <p>Language: en</p>",
