Early prevention during adolescence appears to be one of the most beneficial practices. Exercise is an effective approach for developing bone mass during puberty, but some sports may have a positive or negative impact on bone mass accrual. Plyometric jump training has been suggested as a type of exercise that can augment bone, but its effects on adolescent bone mass have not been rigorously assessed. The aims of the PRO-BONE study are to: 1) longitudinally assess bone health and its metabolism in adolescents engaged in osteogenic (football), non-osteogenic (cycling and swimming) sports and in a control group, and 2) examine the effect of a 9 month plyometric jump training programme on bone related outcomes in the sport groups. Methods/Design: This study will recruit 105 males aged 12-14 years who have participated in sport specific training for at least 3 hours per week during the last 3 years in the following sports groups: football (n = 30), cycling (n = 30) and swimming (n = 30). An age-matched control group (n = 15) that does not engage in these sports more than 3 hours per week will also be recruited. Participants will be measured on 5 occasions: 1) at baseline; 2) after 12 months of sport specific training where each sport group will be randomly allocated into two sub-groups: intervention group (sport + plyometric jump training) and sport group (sport only); 3) exactly after the 9 months of intervention; 4) 6 months following the intervention; 5) 12 months following the intervention. Body composition (dual energy X-ray absorptiometry, air displacement plethysmography and bioelectrical impedance), bone stiffness index (ultrasounds), physical activity (accelerometers), diet (24 h recall questionnaire), pubertal maturation (Tanner stage), physical fitness (cardiorespiratory and muscular), bone turnover markers and vitamin D will be measured at each visit. Discussion: The PRO-BONE study is designed to investigate the impact of osteogenic and non-osteogenic sports on bone development in adolescent males during puberty, and how a plyometric jump training programme is associated with body composition parameters. 000044965 536__ $$9info:eu-repo/grantAgreement/EC/FP7/618496/EU/Effect of a program of short bouts of exercise on bone health in adolescents involved in different sports/PRO-BONE 000044965 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000044965 590__ $$a2.209$$b2015 000044965 591__ $$aPUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH$$b58 / 173 = 0.335$$c2015$$dQ2$$eT2 000044965 592__ $$a1.445$$b2015 000044965 593__ $$aPublic Health, Environmental and Occupational Health$$c2015$$dQ1 000044965 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000044965 700__ $$aBarker, A.R. 000044965 700__ $$aWilliams, C.A. 000044965 700__ $$aKnapp, K.M. 000044965 700__ $$aMetcalf, B.S. 000044965 700__ $$0(orcid)0000-0002-4020-0256$$aGracia-Marco, L. 000044965 773__ $$g15, 1 (2015), 361 [10 pp]$$pBMC Public Health$$tBMC PUBLIC HEALTH$$x1471-2458 000044965 8564_ $$s855038$$uhttps://zaguan.unizar.es/record/44965/files/texto_completo.pdf$$yVersión publicada 000044965 8564_ $$s90441$$uhttps://zaguan.unizar.es/record/44965/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000044965 909CO $$ooai:zaguan.unizar.es:44965$$particulos$$pdriver 000044965 951__ $$a2021-01-21-11:15:22 000044965 980__ $$aARTICLE
