Longitudinal effects of swimming on bone in adolescents: A pQCT and DXA study 2017 Access copy available to the general public Unrestricted The aims of the present study were, firstly, to evaluate areal bone mineral density (aBMD), bone strength and structure during a swimming season and compare them to those of normo-active controls (CG), and secondly to ascertain whether practising an additional weight-bearing sport other than swimming might improve bone. Twenty-three swimmers who only swam (SWI-PURE; 14 males, 9 females), 11 swimmers who combined swimming with an additional weight-bearing sport (SWI-SPORT; 8 males, 3 females) and 28 controls (CG; 16 males, 12 females) participated in the present study. aBMD was assessed with dual energy X-ray (DXA). Bone mass, area, structure and strength of the non-dominant tibia and radius were measured with peripheral quantitative computed tomography (pQCT). Measurements were performed at the beginning of the swimming season and 8 months later. The only difference among groups for DXA and pQCT variables was found for arm aBMD, which was higher in the SWI-SPORT than in the CG group at both pre- and post-evaluation. Group by time interactions (GxT) were found for trochanter aBMD when comparing SWI-SPORT to CG and SWI-SPORT to SWI-PURE, favouring in both cases SWI-SPORT. No GxT were found for the radius. For the tibia, GxT were found between SWI-SPORT and CG and between SWI-PURE and CG, in both cases favouring the swimmers. A season of swimming does not confer any additional benefits to aBMD, but may confer minor benefits to structure and mass. Complementing swimming with a weight-bearing activity is beneficial to bone. info:eu-repo/grantAgreement/ES/MINECO/DEP2011-29093 info:eu-repo/grantAgreement/ES/MINECO/BES-2012-051888 info:eu-repo/grantAgreement/ES/MEC/AP-2012-02854 info:eu-repo/semantics/openAccess by-sa http://creativecommons.org/licenses/by-sa/3.0/es/ 1.729 2017 SPORT SCIENCES 51 / 81 = 0.63 2017 Q3 T2 0.641 2017 Orthopedics and Sports Medicine 2017 Q2 Physical Therapy, Sports Therapy and Rehabilitation 2017 Q2 Physiology (medical) 2017 Q3 Sports Science 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-1132-5906 Gonzalez-Aguero, A.
