Background:In adults ageing is accompanied by changes in limb volume and skin biomechanical properties.Objectives: To explore the relationship between body size, aging, skin biomechanics, and leg volume, V Leg and to define predictive equations linking leg volume with these properties.Methods: Sixty-two healthy adults (Age 18-80 years, M:F 45:55) were recruited.Anthropomorphic measures were recorded along with V Leg (via circumferential method) and skin tone, stiffness, and elastance (via tonometry). Regression analysis was performed to define relationship between the measured parameters.
Results:In healthy adults bilateral V Leg were the same regardless of leg or sex, 5791 ± 1363 for females and 6151 ± 1203 mls for males. V Leg was positively correlated to body weight, where V Leg (mls) = 1058 + 69 × Wt (kg) for females and V Leg (mls) = 539 + 65 × Wt (Kg) of body weight for males. Skin surface biomechanical properties varied with sex, leg volume, and location on the leg with the malleolus exhibiting the stiffest surface.
Conclusion:The study shows that anthropometric measures change with sex and leg size are multifactorial and body weight, sex, and skin condition as important determinant factors of leg volume.
