Maximal Oxygen Consumption and Bone Mineral Density in A Group of Girls
414 2 Musculoskeletal Department, Bellevue Medical Center, Faculty of Medicine of St. Joseph University, Mansourieh, Lebanon
Aims: The aim of this study was to investigate the influence of the weight-status on hip BMD in Lebanese postmenopausal women. Methods: 1411 Lebanese postmenopausal women (422 obese, 568 overweight and 421 normal weight) aged from 50-91 years participated in this study. The women were recruited by advertisements offering BMD measurements at a reduced cost. Subjects with previous surgery on the spine or on the hip, and those with history of radiotherapy or chemotherapy were excluded from this study. Informed written consent was obtained from all the participants. Weight and height were measured, and BMI (kg/m2) was calculated. The population was divided into three groups (obese, overweight and normal weight) according to their BMI. Total hip (TH) BMD, femoral neck (FN) BMD and femoral neck cross-sectional area (FN CSA) were evaluated by DXA (GE Healthcare Lunar Prodigy). Results: TH BMD, FN BMD and FN CSA were higher in obese and overweight women compared to normal weight women (P!0.001). In the whole population, body weight, height and BMI were positively correlated to TH BMD, FN BMD and FN CSA (P!0.001). Conclusion: This study suggests that, in postmenopausal women, obesity is associated with higher hip BMD values and greater femoral neck cross-sectional area values. Hence, our study suggests a protective effect of obesity against osteoporosis. Disclosure of Interest: None Declared
P133 MAXIMAL OXYGEN CONSUMPTION AND BONE MASS IN A GROUP OF BOYS R. El Hage1,*, G. Zunquin2, E. Zakhem1, G. Maalouf3, D. Bougle4; 1Department of Physical Education, University of Balamand, Tripoli, Lebanon, 2Departement STAPS, URePSSS-EA 4110/EA448, ULCO, Dunkerque, France, 3 Musculoskeletal Department, Bellevue Medical Center, Faculty of Medicine of Saint Joseph University, Mansourieh, Lebanon, 4Pediatric Department, CHU de Caen, Caen, France Aims: Although several studies have shown associations between anaerobic performance and bone mass [1,2], little is known concerning the relation between aerobic performance and bone mass. Childhood is a key period for the accumulation of bone mass [3,4]. The aim of this study was to explore the relationship between maximal oxygen consumption (VO2 max) and whole body bone mineral content (WB BMC) in a group of French boys. Methods: 122 French boys whose ages range from 6-16 years participated in this study. Informed written consent was obtained from the parents. Body weight and height were measured, and BMI was calculated. Maximal oxygen consumption (VO2 max) was determined by direct measurement whilst exercising on a bicycle ergometer. WB BMC was measured by DXA. Results: VO2 max (expressed as l/mn) was positively correlated to WB BMC (r250.52; P!0.001). The positive association between VO2 max and WB BMC remained significant after adjustment for age (P!0.001). Conclusion: This study suggests that VO2 max is a positive determinant of WB BMC in boys. Aerobic performance seems to be a determinant of bone mass in growing children. References: [1] Zakhem E, et al. J Clin Densitom 2013;16:129. [2] El Hage R, et al.

P134 MAXIMAL OXYGEN CONSUMPTION AND BONE MINERAL DENSITY IN A GROUP OF ADULT MEN R. El Hage1,*, E. Zakhem1, G. Zunquin2, D. Theunynck2, F. Bachour3, A. Sebaaly3, G. Maalouf3; 1Department of Physical Education, University of Balamand, Tripoli, Lebanon, 2Departement STAPS, URePSSS-EA 4110/EA448, ULCO, Dunkerque, France, 3Musculoskeletal Department, Bellevue Medical Center, Faculty of Medicine of Saint Joseph University, Mansourieh, Lebanon Aims: Although several studies have shown associations between anaerobic performance and BMD [1,2], little is known concerning the relation between aerobic performance and BMD. Peak BMD is a strong determinant of fracture risk later in life [3,4]. The aim of this study was to explore the relationship between maximal oxygen consumption (VO2 max) and BMD in a group of Lebanese adult men.
Abstracts Methods: 24 Lebanese men whose ages range from 18-32 years participated in this study. Informed written consent was obtained from the participants. Body weight and height were measured, and BMI was calculated. Maximal oxygen consumption (VO2 max) was determined by direct measurement whilst exercising on a bicycle ergometer. Whole body bone mineral content (WB BMC), WB BMD, subtotal BMD (WB BMD less head), L1-L4 BMD, total hip BMD (TH BMD), femoral neck BMD (FN BMD), FN cross-sectional area (FN CSA), FN section modulus (FN SM) and FN cross-sectional moment of inertia (FN CSMI) were measured by DXA (GE Healthcare). Results: VO2 max (expressed as l/mn) was positively correlated to WB BMC (r50.51; P!0.05), WB BMD (r50.40; P!0.05), subtotal BMC (r50.64; P! 0.01), L1-L4 BMD (r50.52; P!0.05), FN CSA (r50.46; P!0.05), FN CSMI (r50.43; P!0.05) and FN SM (r50.52; P!0.05). The positive associations between VO2 max and bone variables (BMC, BMD and bone geometry indices) remained significant after adjustment for age (P!0.05). Conclusion: This study suggests that VO2 max is a positive determinant of BMC, BMD and geometric indices of hip bone strength in adult men. Aerobic performance seems to be a determinant of bone mass and bone geometry in adult men. References: [1] Zakhem E, et al. J Clin Densitom 2013;16:129. [2] El Hage R, et al.
