Relación entre composición corporal y movimientos producidos durante la marcha en personas mayores

Objective To explore the relationships between the parameters of body composition and the movements during gait, measured by accelerometers, in healthy and normal weight older people. Material and method The sample consisted of 30 older people with a mean age of 69.7±3.5 years. Functional (Timed Up & Go, Chair Stand Test) and anthropometric (waist circumference and bioelectrical impedance analysis) clinical trials were performed. The accelerometry gait analysis was performed along a corridor of 10 meters (back and forth). Results The weight was correlated with the minimum value of axes 1 and 3. At higher height revealed higher maximum values in axes 1 and 2 and the vector module; and a bigger waist circumference showed higher minimum acceleration value on the axis 2. Among both sexes, significant differences between the basal metabolism, the percentage of fat-free mass, trunk muscle, trunk fat-free mass and percentage of fat mass in lower limbs. Conclusions Height relates to more instability of gait in older people (especially men), which must be taken into account to implement prevention programs when the first signs of deterioration are detected. The accelerometer-based gait analysis and body composition by bioimpedance in older adults, can help identify prematurely impaired balance and postural control.
