Physical Activity Interactions with Bone Accrual in Children and Adolescents

Résumé
Physical Activity Interactions with Bone Accrual in Children and Adolescents 3812008) and controls.Therefore, research investigating the relationship regarding bone markers and different PA types is limited and ambiguous, but even more so in children and adolescents, making it difficult to ascertain the effect of sport on bone.The examination of biochemical measurements of bone turnover, in addition to static measures of bone, is advantageous in the study of skeletal metabolism and growth as they provide an understanding of the dynamic course of bone remodelling.To date, the use of biochemical marks of bone turnover in PA interventions on bone in youth has been extremely limited.Difficulties in comparing and assessing the benefits of PA on bone during growth reflect the varying methodologies used between studies.PA interventions aimed at improving bone health in youth have been subject to limited maturational comparisons as the majority of interventions have been conducted in one distinct pubertal group.Furthermore, the types of PA interventions that have been applied have varied greatly between studies.Discrepancies in results are due in part to the varying bone assessment techniques that are used across cross-sectional and intervention studies.Many of the aforementioned studies measured improvements in BMD using dual-energy x-ray absorptiometry (DXA).The use of DXA to interpret and evaluate BMD in the growing years can be difficult as there are considerable changes to the size and shape of bone (Bailey et al., 1996;Gordon, 2003;Schoenau et al., 2004), making comparisons between youth problematic.Furthermore, the measurements provided by DXA fail to account for the architecture, organization of tissues, mechanical properties and other factors known to impart bone strength.In addition, the bone assessment techniques used in majority of these studies have provided a static rather than dynamic picture of bone, which could in fact allow for more comparisons across studies.Evidence supporting the role of PA on bone health has been accumulated from a wide range of studies investigating different activity methods using athletes, non-athletes and inactive individuals.Although these studies contribute to the literature they do not provide us with causality that PA does impart benefits to bone health.In response, there has been an increase in the number of intervention studies conducted, particularly in the school setting.PA interventions in schools are in many ways ideal places to intervene as they allow for a large population of children and adolescents to be targeted in a somewhat controlled environment, regardless of socioeconomic status, in a location where youth already spend a majority of their day during their most skeletally responsive years (Hughes et al. 2007).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
