“…The association between lean mass and bone accrual might also be due to other factors, such as nutrition, hormones, and genetic factors that have independent effects on muscle and bone. Moreover, muscle power has been shown to be a positive determinant of femoral neck (FN) and total hip BMD, FN cross-sectional area, FN cross-sectional moment of inertia and FN Z-score in 148 women between 18 and 35 years (23). Thus, it can be speculated that exercise, which improves lean mass and muscle power, has a positive effect on peak bone mass accrual, as it has been shown in previous studies (24)(25)(26)(27).…”

Abstract Context Consensus regarding diagnosis and management of osteoporosis in premenopausal women (PW) is still lacking due to few studies carried out in this population. Design The European Calcified Tissue Society and the International Osteoporosis Foundation convened a working group to produce an updated review of literature published after 2017 on this topic. Results Fragility fractures in PW are rare and mostly due to secondary osteoporosis (ie, in presence of an underlying disease such as hormonal, inflammatory, or digestive disorders). In absence of another disorder, low bone mineral density (BMD) together with fragility fractures qualifies as idiopathic osteoporosis. In contrast, low BMD alone does not necessarily represent osteoporosis in absence of bone microarchitectural abnormalities. BMD increases in PW with osteoporosis when the underlying disease is treated. For example, in celiac disease, an increase of 9% in radius trabecular volumetric density was achieved after 1 year of gluten-free diet, while anti-tumor necrosis factor alpha improved BMD in PW with inflammatory bowel diseases. In amenorrhea, including anorexia nervosa, appropriately delivered estrogen replacement therapy can also improve BMD. Alternatively, antiresorptive or anabolic therapy has been shown to improve BMD in a variety of conditions, the range of improvement (3%-16%) depending on skeletal site and the nature of the secondary cause. No studies were powered to demonstrate fracture reduction. The effects of bisphosphonates in childbearing women have been scantly studied and caution is needed. Conclusion The majority of PW with osteoporosis have an underlying disease. Specific therapy of these diseases, as well as antiresorptive and anabolic drugs, improve BMD, but without evidence of fracture reduction.

“…However, it is noteworthy that literature data on the association between physical fitness and bone mass are still controversial. Although longitudinal studies have pointed out specific physical capacities as influencing factors in long-term osteogenesis ( Kemper, 2000 ; Vicente-Rodríguez et al, 2008 ; Khawaja et al, 2019 ), other studies have shown that only muscle fitness ( Sayers et al, 2011 ; Torres-Costoso et al, 2020 ) is associated with BMD, although others have found a relationship with cardiorespiratory fitness ( Dib et al, 2005 ; Ginty et al, 2005 ; Vicente-Rodríguez et al, 2008 ).…”

The associations between bone mass and physical fitness variables can be based on evidence on the osteogenic effect in childhood of some types of physical exercise (Rutherford, 1999;Vicente-Rodríguez, 2006).…”

Sprint and upper limbs power field tests for the screening of low bone mineral density in children

Background: The possibility of carrying out screening, with acceptable accuracy, of a child’s bone mass status based on a physical fitness test can advance the concept of health-related physical fitness. In addition, the relevance of the applicability of this type of screening in educational environments is mainly due to the difficulty of direct assessments of bone health indicators. This study aimed to propose cut-off points for physical fitness tests based on children’s bone health indicators.Methods: This is a two-phase cross-sectional study. Phase-1: 160 children (6–11 years-old) performed the 20-m sprint test (20-mST) and the 2 kg medicine ball throw test (2 kgMBTT). Areal bone mineral density (aBMD) and content was assessed by DXA. The area under the ROC curve greater than 70% was considered valid. Phase-2: It was carried out a secondary analysis in a sample with 8,750 Brazilians (6–11 years-old). The percentile values (identified in phase-1) were used to identify the values of the cut-off points in the unit of measurement of the tests. The validation of the cut-off points found was by odds ratio values and p ≤ 0.05.Results: Phase 1: The areas under the ROC curve were 0.710, 0.712 (boys and girls–20-mST), 0.703, and 0.806 (boys and girls–2 kgMBTT) with total spine and pelvis aBMD as the outcome. Phase 2: From percentile values, we find valid cut-off points in the Brazilian sample (OR > 3.00; p < 0.001) for boys and girls. Values ranged between 5.22 s–4.00 s to 20-mST and between 125.0 cm–160.0 cm to 2 kgMBTT. Conclusion. The 20-mST and the 2 kgMBTT presented sufficient accuracy for the screening of children aged between 6 and 11 years with greater chances of having low aBMD in the total spine and pelvis, with valid cut-off points.

“…Although most of the normative data for muscular power assessments are for athletes, preassessments and postassessments will provide information on the functional status of a general fitness client in terms of ADLs, exercise, and sport. For example, power, measured by a vertical jump test, is a positive determinant of whole-body bone mineral density in healthy men and women, aged 18 to 35 years (40). Other examples of muscular power tests may include the standing long jump, Margaria-Kalamen (31) stair sprint test, and standing power throw (Table 8).…”
