Experts claim that 10,000 steps per day isn’t a magical solution.
Reaching 10,000 steps daily has become a widespread health objective for many people around the globe.
However, a more efficient option might prove effective for shedding pounds, according to experts.
Walking with an irregular pace might aid in burning more calories compared to taking evenly measured strides, according to research.
American researchers monitoring the activities of 18 fit participants found that for each 1 percent increase in stride variation, there was a corresponding 0.7 percent boost in energy consumption.
The study indicated that inconsistent steps ‘have a minor but notable impact’ on the energy expended during walking, according to the researchers.
The team failed to gauge the number of calories expended by the participants.
Nevertheless, Adam Grimmitt, a co-author of the study and an expert in exercise physiology at the University of
Massachusetts
Amherst stated, “It seems reasonable to conclude that greater and more frequent changes in step length would lead to an increased metabolic rate during walking.”
In the study, the participants—ranging from 24 years old and averaging 11 stone 1 pound (70.5 kg)—were instructed to walk at their usual pace for five minutes on a treadmill.
A motion capture system documented their typical stride length at a usual pace of 1.2 meters per second.
They subsequently controlled their movements during a second 5-minute treadmill walking session by illuminating specific areas for the participants to target.
Positions were adjusted by as much as five and 10 percent below or above the typical stride length.
Each volunteer was equipped with a mouthpiece that measured their carbon dioxide output rate, which increases during physical activity.

The researchers suggest that when individuals transition between maintaining stability over short steps and long steps, it can lead to increased muscle contractions and subsequently higher metabolic costs.
‘Their findings indicate that a 2.7 percent rise in step length variability could lead to a 1.7 percent increase in the energy required for walking,’ they noted.
‘The variation in step length moderately but importantly influences the energy expended during walking.’
The research might be most applicable to elderly individuals, especially those suffering from neurological disorders, since their walking patterns show ‘higher step length variability,’ they added.
Researchers, nevertheless, admitted that adjusting lengths in 5 percent increments differs from actual variations observed in natural walking patterns.
The participants still found it difficult to maintain precision when adjusting their stride lengths without extra guidance, they noted.
‘Studies focused on the future should measure the precision of foot positioning and muscle activity across comparable virtual displays.’
