Doing exercise in short bouts makes you spend more energy than if you'd done the same amount of exercise continuously, according to international researchers. The team tested how much oxygen people consumed while walking on a treadmill and a stair climber, comparing a series of different bouts from 10 seconds to four minutes. They say the shorter the exercise bout, the more oxygen was used, and after extrapolating the data they say exercising in 10-30 second bouts could use 20-60% more oxygen compared to doing the same amount continuously. The researchers say this shows we can make a difference with small bits of activity, and people with mobility issues can get the benefits of exercise even if they can only move for short periods.

  • Wait gains – Taking breaks on your morning walk could help burn more energy. Researchers found that walking or climbing stairs in short 10- to 30-second bouts makes people consume 20 to 60% more oxygen compared to doing it continuously for the same distance. “Thus breaking up sedentary time with brief strolls or taking the stairs can greatly increase energy expended daily and improve health”, the authors said.

Move less, spend more: The metabolic demands of short walking bouts.

Taking breaks while walking makes you spend more energy. In this experiment, researchers found that walking or climbing stairs in short 10- to 30-second bouts makes people consume 20 to 60% more than doing it continuously for the same distance. Thus, breaking up sedentary time with brief strolls or taking the stairs can greatly increase energy expended daily and improve health. These findings also help quantifying energy use in animals who move intermittently and improving management for people with impaired mobility, who often can move for only few steps. In all cases, moving for shorter bouts can mean spending more!
