Abstract: 
Objective: The aim of this study was to examine the associations between physical activity level and composite indices of femoral neck strength in a group of young overweight and obese Lebanese men. Methods: Eighty overweight and obese (body mass index (BMI) > 25 kg/m ) young men whose ages range between 18 and 35 years participated in this study. Weight and height were measured, and BMI was calculated. Body composition and femoral neck (FN) bone mineral density were measured by dual-energy X-ray absorptiometry (DXA). Compressive strength index (CSI), bending strength index (BSI) and impact strength index (ISI) were calculated. Physical activity level was evaluated by the global physical activity questionnaire (GPAQ). Maximum oxygen consumption (VO max, in L/min) was measured using a valid device. Results: Weight, BMI, fat mass and fat mass percentage were negatively correlated to CSI, BSI and ISI. Physical activity level (h/week) was positively correlated to CSI, BSI and ISI while VO max (mL/min/kg) was positively correlated to CSI and ISI. The positive associations between physical activity and composite indices of femoral neck strength (CSI, BSI and ISI) remained significant after adjustment for body weight. Conclusion: Our study conducted on overweight and obese men shows that physical activity level is a positive determinant of composite indices of femoral neck strength. In overweight men, increasing physical activity level may help to prevent osteoporotic fractures later in life. 2 2 2
