However, the effectiveness of organized physical activities (OPAs) in attenuating or delaying these age-related transformations remains an area of limited understanding. The primary objectives of this study were threefold: (I) to comprehensively assess the evolution of body composition in a cohort of Spanish older adults over an 8-year period; (II) to compare this evolution in the different age groups; and (III) to investigate the influence of active engagement in OPAs on these age-related changes. From a sample of 3136 Spanish older adults recruited in 2008, 651 agreed to participate in the 8-year follow-up. Anthropometric and bioelectrical impedance data were included for 507 females (70.3 ± 4.4 years) and 144 males (77.8 ± 4.5 years). Age groups were categorized as follows: youngest (65–69 years), mid (70–74 years), and oldest (≥75 years). The engagement in OPA was recorded before and after the follow-up. A repeated measures ANOVA was performed to evaluate the 8-year changes. Males increased in hip (98.1 ± 9.3 vs. 101.5 ± 10.2 cm) and waist circumferences (101.2 ± 6.6 vs. 103.2 ± 6.1 cm), specifically in the youngest group (p < 0.05). Females decreased in weight (67.6 ± 10.0 vs. 66.6 ± 10.5 kg) and fat mass percentage (39.3 ± 5 vs. 38.8 ± 5.4%) and increased in hip circumference (104.4 ± 9.0 vs. 106.5 ± 9.7 cm); these effects were the most remarkable in the oldest group (all p < 0.05). OPA engagement seemed to slow down fat-free mass loses in males, but not in females (grouped by time, p < 0.05). Body composition changes caused by aging seem to happen earlier in males than in females. Moreover, participating in OPAs does not prevent fat-free mass due to aging. 000131220 536__ $$9info:eu-repo/grantAgreement/ES/MECD/CB16-10-00477$$9info:eu-repo/grantAgreement/ES/MECD/EXERNET-DEP2005-00046$$9info:eu-repo/grantAgreement/ES/MICINN-FEDER/IMSERSO-147-11$$9info:eu-repo/grantAgreement/ES/MINECO/DEP2016-78309-R$$9info:eu-repo/grantAgreement/ES/UZ/UZCUD2016-BIO-01$$9info:eu-repo/grantAgreement/ES/UZ/UZCUD2017-BIO-01$$9info:eu-repo/grantAgreement/ES/UZ/2008-BIO-01 000131220 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000131220 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000131220 700__ $$0(orcid)0000-0001-6492-2512$$aGomez-Cabello, Alba 000131220 700__ $$aMañas, Asier 000131220 700__ $$aGesteiro, Eva 000131220 700__ $$0(orcid)0000-0002-4054-9132$$aPérez-Gómez, Jorge 000131220 700__ $$0(orcid)0000-0001-7757-3235$$aGonzález-Gross, Marcela 000131220 700__ $$0(orcid)0000-0002-7215-6931$$aCasajús, Jose Antonio$$uUniversidad de Zaragoza 000131220 700__ $$0(orcid)0000-0002-2854-6684$$aAra, Ignacio 000131220 700__ $$0(orcid)0000-0002-4303-4097$$aVicente-Rodríguez, Germán$$uUniversidad de Zaragoza 000131220 7102_ $$12008$$2640$$aUniversidad de Zaragoza$$bDpto.
