Eight adolescent male cyclists aged between fourteen and twenty, and eight age-matched controls participated in this longitudinal study. Serum osteocalcin (OC), amino-terminal propeptide of type I procollagen (PINP), beta-isomerized C-telopeptides (-CTx) and plasma 25 hydroxyvitamin D [25(OH)D], were investigated by an electrogenerated chemiluminescence immunoassay. Analysis of variance revealed no significant differences in formation and resorption markers between cyclists and controls. Within the groups, both CYC and CON showed decreased OC at -30% and -24%, respectively, and PINP where the figures were -28% and -30% respectively (all p < 0.05). However, only the CYC group showed a decrease in [25(OH)D], lower by 11% (p < 0.05). The similarity in the concentrations of markers in cyclists and controls seems to indicate that cycling does not modify the process of bone remodeling. The decrease in vitamin D in cyclists might be detrimental to their future bone health. 000079774 536__ $$9info:eu-repo/grantAgreement/ES/DGA/SGI-216177$$9info:eu-repo/grantAgreement/ES/MEC/21-UPB20-10$$9info:eu-repo/grantAgreement/ES/ISCIII/DPS2008-06999 000079774 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000079774 590__ $$a4.546$$b2019 000079774 592__ $$a1.329$$b2019 000079774 591__ $$aNUTRITION & DIETETICS$$b17 / 89 = 0.191$$c2019$$dQ1$$eT1 000079774 593__ $$aNutrition and Dietetics$$c2019$$dQ1 000079774 593__ $$aFood Science$$c2019$$dQ1 000079774 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000079774 700__ $$aOlmedillas, H. 000079774 700__ $$aGonzalez-Aguero, A. 000079774 700__ $$aGomez-Cabello, A. 000079774 700__ $$0(orcid)0000-0002-6829-0775$$aPradas de la Fuente, F.$$uUniversidad de Zaragoza 000079774 700__ $$0(orcid)0000-0003-0454-653X$$aMoreno, L.A.$$uUniversidad de Zaragoza 000079774 700__ $$0(orcid)0000-0002-7215-6931$$aCasajus, J.A.$$uUniversidad de Zaragoza 000079774 700__ $$0(orcid)0000-0002-4303-4097$$aVicente-Rodriguez, G.$$uUniversidad de Zaragoza 000079774 7102_ $$13001$$2187$$aUniversidad de Zaragoza$$bDpto.
