Scientists from the medical research institute based in Paris, Inserm, found that people who are older and slow almost three times more likely to die of heart disease and other related causes compared with those older and run faster.
"The main message for the general population is to maintain fitness in old age may have important consequences and help preserve life and function of muscle," said researcher Alexis Elbaz, Inserm Director of Research, told Reuters Health.
He said the study, published in the journal BMJ, has also shown that people walking speed tests may be used to check the health of elderly patients.
Several previous studies have linked the slow people walking with an increased risk of dying during a given period, and with other results of poor health, but did not show whether it is a heart disease or other causes responsible for the greater risk it.
Studies for five years, part of the Three Cities Study, which was conducted by Inserm, involving more than 3,200 men and women who are relatively healthy and aged 65 to 85 years. They lived in three cities in France.
At the beginning of the study in 1999, the scientists assess the health of each participant and calculated the speed of the participants as they walked in the corridor as quickly as possible.
Over the next five years, 209 participants died - 99 percent of cancer, 59 due to heart disease, and 53 due to infectious diseases and other causes - and the overall mortality rate of almost 7 percent.
The death rate among one third of participants who walked at the latest, a man who walked with about 3.4 miles per hour or even slower and women who walked about three miles per hour or slower, 44 perser is higher than in the two-thirds of participants who have run faster.
Deaths from heart attacks, strokes and other related causes was 2.9 times more common among third of participants who walked at least compared with participants who run the fastest.
The increase in mortality due to heart disease seen in men and women and not related to the age of the participants or how they are physically active.
The researchers found no link between walking speed and other causes of death, including cancer.
What explains the connection between slow and deaths from heart disease?
Elbaz says one possibility is that the same risk factors that increase the risk of heart disease - high blood pressure and diabetes - also resulted in "silent stroke", which makes people difficult to walk fast. The idea was "worthy of study followed by a further confirms it", he said. (ANTARA News)
