It is key that the development of this muscle fitness is affected by absolute isometric strength and dynamic strength. Purpose To compare bone health and body composition between overweight/obese children considering muscular fitness (MF) levels, and to investigate whether weight-bearing dynamic or absolute isometric strength, both involved in the development of this muscular fitness, are more related with bone health. Methods MF of 59 overweight or obese children (10.1 ± 0.9 years, 27 females) was measured by a countermovement jump (CMJ), handgrip, and maximal isometric strength of knee extension. Participants were divided into four groups depending on their MF level performing a cluster analysis: 16 children with high MF (HMF) in all tests, 18 with high performance in isometric strength (HIS), 15 with high performance in CMJ (HCMJ) and 10 low isometric and low dynamic force values (LMF). Body composition values were measured by dual energy X-ray absorptiometry, and bone strength values were assessed by peripheral quantitative computed tomography. Motor skills were evaluated using TGMD-3. Multivariate analysis of covariance test was applied to analyse bone strength differences between children in the different MF groups, using maturity offset, height and weight as covariates, and correlations were investigated. Results HMF excelled in bone health. HIS had higher cortical bone area, periosteal circumference, bone mass, polar strength strain index and fracture load than LMF, while HCMJ only showed better results in trabecular bone area than LMF. HMF had significantly better values of fracture load and periosteal and endosteal circumferences than HCMJ, but not than HIS. Conclusions High MF level shows positive effects on bone health in overweight/obese children. Those with highest isometric strength had better bone health compared to those with higher dynamic strength. info:eu-repo/grantAgreement/ES/DGA-FSE/IIU-2023-2017 info:eu-repo/grantAgreement/ES/MINECO/DEP2017-85194-P info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.8 2024 ORTHOPEDICS 30 / 140 = 0.214 2024 Q1 T1 ENDOCRINOLOGY & METABOLISM 104 / 193 = 0.539 2024 Q3 T2 0.938 2024 Orthopedics and Sports Medicine 2024 Q1 5.9 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Villalba-Heredia, Lorena (orcid)0000-0002-3847-3300 Lozano-Berges, Gabriel Universidad de Zaragoza (orcid)0000-0002-0137-9900 Matute-Llorente, Ángel Universidad de Zaragoza (orcid)0000-0001-8500-1667 Marín-Puyalto, Jorge (orcid)0000-0002-1042-542X Vicente-Rodríguez, Germán Universidad de Zaragoza (orcid)0000-0002-4303-4097 Casajús, José A.
