Abstract
Musculoskeletal fitness (MSF) predicts youth health, but prior research has focused on separate MSF domains, limiting understanding of whole-body MSF.
Purpose: To use latent profile analysis to identify MSF profiles and evaluate whether weight status and moderate to vigorous physical activity predict profile.
Methods: Data came from the 2012 National Health and Nutrition Examination Survey National Youth Fitness Survey for participants ages 12-15 years (N = 442). Latent MSF profiles were generated using modified pull-up, leg extension, grip strength, and plank assessments. Multinomial logistic regression models controlled for age and sex.
Results: Fit statistics were optimal for a 3-profile model: Profile 1: high leg extension and grip strength, Profile 2: high pull up and plank, and Profile 3: low overall MSF. Participants in Profile 1 were 6.25 (95% CI, 1.82-21.52) times as likely to be overweight than Profile 2, and 6.21 (95% CI, 1.61-23.94) times as likely to have obesity than Profile 3. Participants in Profile 2 were 5.85 (95% CI, 1.99-17.18) and 5.34 (95% CI, 2.14-13.36) times as likely to be active than Profile 1 and Profile 3, respectively.
Conclusions: Profile 1 shows higher levels of overweight/obesity in children than Profile 3, suggesting that a healthy body mass index does not necessarily equate to greater MSF. Findings suggest MSF assessments are not consistently linked to weight status or moderate to vigorous physical activity, and future research should use multiple assessments to account for fitness differences.
期刊介绍：
Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach.
Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
