Your walking speed could reveal more about your health than step count alone. Here's what research says about slow walking, gait speed and the 0.8 m/s benchmark.
Walking is often considered one of the simplest ways to stay healthy. Whether it is a morning stroll, a walk after dinner or simply moving around during the day, most people tend to measure their activity through the number of steps they take. But there is another aspect of walking that may deserve just as much attention: how quickly you walk.
A study published in JAMA Network Open has found an association between walking speed, walking cadence and the risk of death from any cause. The findings suggest that the pace at which a person walks could offer important insights into their overall health, even when their daily step count is taken into account.
The study, titled Clinical Walking Speed, Free-Living Walking Cadence, and All-Cause Mortality, examined 4,067 participants from the UK-based Whitehall II study. The participants had an average age of 69.3 years and were followed for a median period of 11.8 years.
Researchers assessed walking speed through a clinical walking test and measured everyday walking cadence using wrist-worn accelerometers. They found that higher walking speeds and cadences were associated with a lower risk of all-cause mortality, even after accounting for several demographic, lifestyle and health-related factors, as well as daily step counts.
But what does your walking pace reveal about your body? And when should a slower walking speed prompt you to pay attention?
Why does walking speed matter?
Walking may appear effortless, but it involves several systems working together. The heart and lungs supply oxygen to the body, muscles generate the strength needed for movement, while the nervous system and brain coordinate balance, posture and movement.
This is why walking speed is often considered an indicator of functional health. A person’s ability to maintain a comfortable pace can offer clues about muscle strength, cardiovascular fitness, coordination and overall physical capacity.
A noticeable decline in walking speed may sometimes accompany age-related muscle loss, cardiovascular problems, neurological conditions, joint disorders or general frailty.
It is also important to understand that walking speed and step count measure different things. While step count indicates how much a person walks, walking speed and cadence offer additional information about the pace and intensity of that movement.
In fact, the JAMA study found that the association between walking parameters and mortality remained evident even after researchers adjusted for daily step count. This suggests that simply reaching a daily step target may not tell us everything about a person’s mobility or functional health.
However, the findings establish an association, not proof that walking faster will directly increase life expectancy.
What does a walking speed below 0.8 metres per second mean?
A walking speed of 0.8 metres per second is equivalent to approximately 2.9 kmph. It is a recognised clinical reference point in assessments of physical function, particularly among older adults.
The European Working Group on Sarcopenia in Older People has used a gait speed of 0.8 metres per second or less as an indicator of poor physical performance when assessing severe sarcopenia, a condition characterised by reduced muscle strength and muscle function.
However, this does not mean that everyone walking below this speed has sarcopenia or is at an increased risk of dying. The threshold is not a universal mortality cut-off, and the JAMA study did not establish 0.8 metres per second as a specific danger point.
Age, height, fitness levels, joint problems, neurological conditions and existing health concerns can all influence walking speed.
What may be particularly important is a change from someone’s usual pace. For instance, if a person who previously walked comfortably now struggles to cover the same distance, becomes unusually tired or needs frequent breaks, the change should not automatically be dismissed as a natural part of ageing.
How can you check your walking speed at home?
You do not necessarily need specialised equipment to get an idea of your walking speed. A simple timed walking test can help you assess your mobility.
Here is how you can do it:
Mark a straight, flat distance of 10 metres.
Walk the distance at your normal, comfortable pace.
Record the time taken using a smartphone stopwatch.
Divide the distance (10 metres) by the time taken in seconds to calculate your walking speed in metres per second.
For example, if you cover 10 metres in 10 seconds, your walking speed is 1 metre per second. If you take 12.5 seconds, your speed is 0.8 metres per second.
You can repeat the test periodically under similar conditions to monitor changes in your walking speed.
However, a home test is not a substitute for a clinical assessment. Standardised gait-speed tests may use different walking distances and protocols, so results should be interpreted in context.
When should you be concerned about slowing down?
A slower walking speed does not automatically indicate a serious health condition. However, a persistent or unexplained reduction in mobility deserves attention.
Pay particular attention if the change is accompanied by:
Unexplained fatigue or weakness.
Breathlessness during activities that were previously comfortable.
Dizziness or frequent loss of balance.
Difficulty getting up from a chair or climbing stairs.
Changes in coordination or an increased tendency to fall.
These symptoms can have several possible causes and may warrant a medical assessment. A healthcare professional can evaluate muscle strength, cardiovascular health, neurological function, joint mobility and other factors that may be affecting movement.
The takeaway? Counting your steps is useful, but paying attention to how comfortably and efficiently you walk can offer another perspective on your health. Your walking pace may not tell you everything about your health, but changes in it are worth noticing.
