Lower limbs relative strength and composite indices of femoral neck strength in a group of young adult men

Abstract

Introduction: The aim of the current study was to investigate the relationships between relative strength of the lower limbs and composite indices of femoral neck strength (compression strength index [CSI], bending strength index [BSI] and impact strength index [ISI]) in a group of young adult men. Summary of facts and results: In all, 54 Lebanese young men whose ages range from 20 to 30 years (24.4 ± 3.1 years) participated in our study. Body composition and hip bone mineral density were assessed by DXA. CSI, BSI and ISI were calculated. One-repetition maximum (1-RM) half-squat, 1-RM deadlift and 1-RM bench-press were measured. 1-RM half-squat/body mass was positively correlated to CSI (r = 0.35; P < 0.01), BSI (r = 0.33; P < 0.05) and ISI (r = 0.32; P < 0.05), but negatively correlated to fat mass percentage (r = −0.37; P < 0.01). Conclusion: The current study suggests that relative muscular strength of lower limbs is positively correlated to composite indices of femoral neck strength in young men.
