Recent findings reveal that walking briskly for just 15 minutes daily can significantly lower the risk of premature death, particularly among low-income and Black populations. A study published in the American Journal of Preventive Medicine supports this claim.
Researchers analyzed data from nearly 80,000 participants, discovering that active walking was linked to a 20% decrease in overall mortality rates.
This reduction is especially pronounced for deaths related to cardiovascular issues, demonstrating the distinct advantages of maintaining an active pace, independent of other physical activities.
“While the health benefits of daily walking are well-documented, there has been limited research on how variables like walking speed influence mortality, particularly in low-income and Black/African-American communities,” noted Chief Investigator Dr. Wei Zheng from Vanderbilt University Medical Center.
“Our study indicates that a brisk 15-minute walk correlates with nearly a 20% reduction in total mortality.”
In comparison, slower walking for over three hours a day is associated with only a modest 4% decline in mortality, indicating that intensity matters.
The participants, primarily low-income and Black individuals across 12 states in the southeastern U.S., reported their average daily “slow” and “fast” walking. Their health outcomes were monitored over a median follow-up period of 16.7 years.
The advantages of brisk walking persisted even after controlling for other lifestyle factors such as diet, smoking, and alcohol consumption.
Fast walking confers numerous cardiovascular benefits, including improved cardiac function and a reduction in risk factors like obesity, high blood pressure, and high cholesterol.
The researchers emphasized that this activity is low-cost and low-impact, making it accessible to individuals at all fitness levels and an effective intervention in communities with limited healthcare and recreational resources.
To raise awareness, Dr. Lili Liu from the Public Health Campaign and Community Programme stated, “We highlighted the significance and accessibility of brisk walking to enhance health outcomes, and the need to provide resources and support that facilitate easier and faster walking.”
“Individuals should aim to incorporate more intense physical activities into their daily routines,” he added.
