Seniors have reaction time to brake 39.6% higher than in young adults

A study conducted by the Hospital of the Faculty of Medicine, University of São Paulo (USP) shows that elderly drivers have reaction time to brake 39.6% higher than in young adults.

With this delay in reaction to a situation that requires a braking faster, it is recommended that the old drive in the most favorable conditions, the doctor says Julia Greve, guiding the research.

The test, conducted in a simulator, showed that the average reaction time from the stop plate to the braking was 1.34 second for the elderly, while the control group of young adults that time was 0.96 seconds.

The difference in time between study and control groups of young adults to perform the route was 7%.

According to physiotherapist Angelica Castillo, Institute of Orthopaedics and Traumatology, HC, this was not a very significant time difference. Over the years, people tend to be more careful and directing more slowly explains.

The age of drivers evaluated was 74.3 years for men and 69.4 for women. They drive on average for 48.5 years, and 40.6 years for them. Despite the greater reaction time, 97% of study participants were not involved in accidents in the last 5 years, nor were fined last year.

The cars of women have around 5.7 years and men 10.7 years. All assessed drive their cars on rainy days, busy roads, and in the rush hour. Most drivers surveyed 73% female and 87% male drive overnight.

Change lanes, make beacon, ramps, and reading plates are maneuvers that represent some degree of difficulty to 33% of women and 26.65% men. The distance is not a problem for most drivers 100% of men and 87% of women driving anywhere.

All respondents during the survey considered themselves careful in traffic. Of the women, 27% had considered quitting driving, and men, only 13%. Medical recommendation, request familiar, easy to use other means of transport, or the self-perception of disability are the reasons that lead the research group to stop driving, Angelica ends.
