Sitting all day may sabotage your workout, new study shows
NCT ID NCT06301243
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how a day of inactivity (less than 5,000 steps) affects the way muscles and energy systems respond to exercise the next day. Eleven healthy adults who were not regular exercisers took part. Researchers measured fat and carbohydrate burning and muscle gene activity before, during, and after one hour of cycling. The goal was to understand why some people get less benefit from exercise after periods of sitting.
