One goal reduced sitting time; another added standing breaks

In a 30-adult pilot, the standard sensor counted about 13 extra stand-ups; detailed counting in a subgroup found about 40.

How we make these readings

The key idea

Sitting less and standing up more are different goals, and each requires a different measure.

The study, in plain language

Thirty adults ages 50 to 70 tried one of two goals for two weeks: reduce total sitting time or add standing breaks. Researchers randomized who received each. Participants met with an educator and received tools adapted to their routines. A thigh-worn sensor recorded posture, with a prior week as a baseline.

The group focused on sitting less reduced that time, with no detected change in how often they stood up. Using the standard settings, the other group added about 13 stand-ups per day and did not reduce total sitting hours. However, a subgroup measured with more sensitive detection showed an increase of about 40 per day. The standard settings did not count stand-ups shorter than 10 seconds, so the initial record underestimated them.

What they found

  • The group aiming to reduce sitting time cut it by about 130 minutes per day, with no change in stand-ups.
  • The group aiming to stand more added about 13 transitions per day according to the standard sensor; a detailed count in a subgroup estimated about 40. Sitting time did not decrease.
  • This was a two-week pilot with 30 people and no inactive comparison group.

How they studied it

Thirty adults ages 50 to 70 were randomized to two groups, each with a different goal for 14 days: sit less or stand more. A thigh sensor recorded posture, and changes were compared with a prior week. This was a short pilot with 30 adults, two active goals, and no inactive comparison group.

What the study cannot show

  • This was a small, short pilot without an inactive group or health measurements. Participants were mostly white and college-educated.
  • The sensor’s threshold changes the count of brief breaks.

Something to think about

If you set out to move more, what exactly would change? How much time you spend sitting and how often you stand are different questions.
