Short Bursts of Walking Boost Calorie Burn, Study Finds

A recent study suggests that taking short rest breaks during walks can significantly enhance calorie burning.

Conducted by researchers at the University of Milan, the study challenges traditional notions of steady-state exercise, revealing that intermittent walking may lead to greater energy consumption.

In a controlled laboratory setting, volunteers participated in tests measuring oxygen and energy usage during various walking sessions.

Researchers discovered that walking or climbing stairs in short intervals of 10 to 30 seconds increased oxygen demand by 20 to 60% compared to continuous walking over the same distance.

This phenomenon occurs because the body operates less efficiently in the initial moments of movement.

“When we walk for shorter bouts, we use more energy and consume more oxygen to cover the same distance,” explained Francesco Luciano, the study’s lead author.

He likened this to a car that consumes more fuel during the first few kilometers of a journey compared to when it’s cruising at a steady pace.

The researchers examined 10 healthy participants on a treadmill and stair climber, analyzing their oxygen consumption during various walking speeds and intervals.

Findings revealed that initiating movement incurs a fixed energy cost, as more oxygen is required to begin walking.

This cost is proportionally higher for shorter walking bouts, suggesting that brief bursts of activity could be more beneficial for less active individuals.

These insights underscore the health benefits of brief, vigorous activities, known as “exercise snacks,” which are particularly advantageous for sedentary individuals.

The research also has implications for rehabilitation programs aimed at those with limited mobility, such as the elderly or stroke survivors.

By understanding the energy demands of short walking intervals, exercise recommendations can be tailored to promote inclusivity and encourage physical activity among diverse populations.
