Age-related changes of the latent period of simple sensorimotor reaction to the light stimuli in both men and women with different body mass index

Abstract

The study of the relationship of the latent period of simple sensorimotor reaction to the light stimulus and body mass index (BMI) in males and females aged 30-60 years (n = 507) was done. The boundary between the low (below Me – 1SD) and middle (from Me – 1SD to Me + 1SD) BMI was the value of 22.74 kg/m2, the boundary between the middle and high (above Me + 1SD) BMI – 33.16kg/m2. It is shown thatthere isan increase inthe proportion of peoplewith highBMI withage(faster and morepronounced – in women). Sensorimotorreaction latencyto thelight stimulidoes not change in men, anddeclines with agein women. However the data obtained indicate that developed with age alimentary obesity does not adversely affect neurophysiological parameters of the sensorimotor reactivity.
