Abstract

Objectives: The effect of variation in contraction force is one of the most important factors in the organization and execution of REACTION TIME (RT) tasks that most elderly are involved in when they became obese. We aimed to test the effect of limb weight varying on pre-motor and motor components of simple and discriminative REACTION TIME in ELDERLY MEN.Methods & Materials: 16 men with a mean age of 59.18 years were asked to perform forearm flexion towards the target point in 60 cm distance in response to auditory stimulus. The weight of involved limb increased (1.2 kg) at 50% of trials and all trials were measured by electromyogram apparatus.Results: The results of two way repeated measure test showed that the main effects of weight and stimulus on PMT was significant, but the effect of stimulus increasing on MT was not significant (P=0.189). We found no significant interaction effects between limb weight and stimulus increasing on PMT (P=0.888) and MT (P=0.091).Conclusions: These results suggested that the variables that cause variation in limb inertia can affect RT movement of elderly people.
