Nevertheless, it is still unknown if these effects are due to swimming or to other factors, such as sedentary behaviors. INTRODUCTION: Three objectives were described (1) to measure objective physical activity (PA) additional to swimming performed by adolescent swimmers (SWI) and compare it to that performed by normo-active controls (CG), (2) to describe the relationship between objectively measured PA and bone mass, and (3) to compare bone mass of swimmers that meet the World Health Organization PA guidelines (active) WHO and those that do not (inactive). METHODS: A total of 71 SWI (33 females) and 41 CG (17 females) wore an accelerometer for at least 4 days. PA was expressed as the amount of time (minutes/day) in each intensity [sedentary/light/moderate or vigorous (VPA), and the sum of moderate and vigorous (MVPA)]. Using the cutoff points proposed by Vanhelst et al. SWI were classified as active or inactive according to whether they reached 60 min of weight-bearing MVPA per day or not. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry, and bone strength values were calculated with peripheral quantitative computed tomography. Differences in PA intensities were calculated between SWI and CG. The relation of VPA to bone mass was studied in the SWI. RESULTS: Male-SWI spend less time in VPA and MVPA than male-GC, which partly explains the lower BMD values in SWI than CG. CONCLUSION: Swimming may displace weight-bearing VPA with serious implications on bone health. info:eu-repo/grantAgreement/ES/MINECO/BES-2012-051888 info:eu-repo/grantAgreement/ES/MICINN/DEP2011-29093 info:eu-repo/grantAgreement/ES/MEC/AP-2012-02854 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.445 2015 ENDOCRINOLOGY & METABOLISM 45 / 131 = 0.344 2015 Q2 T2 1.48 2015 Medicine (miscellaneous) 2015 Q1 Endocrinology, Diabetes and Metabolism 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-9129-2157 González Agüero, Alejandro Universidad de Zaragoza (orcid)0000-0001-6492-2512 Gómez Cabello, Alba (orcid)0000-0001-8500-1667 Matute Llorente, Angel Universidad de Zaragoza (orcid)0000-0002-7215-6931 Casajús, Jose A.
