Small movement goals lead to more activity
A peer-reviewed study found that participants with daily goals exercised more over three weeks than a comparison group.
A study by City St George’s, University of London, suggests that very small daily movement goals can help people become more active. The researchers compared a daily three-minute goal with a schedule of less frequent, longer sessions.
The study involved 142 participants. They were randomly divided into two groups. The first group was given the goal of moving for three minutes every day, as well as completing two 20-minute sessions per week. The second group was given two 30-minute sessions per week as its goal.
The participants recorded their exercise time, enjoyment and perceived feasibility over three weeks. The group with the daily micro-goal exercised significantly more overall than the group with the standard goal. According to the researchers, the main factor was that the daily goal was easier to maintain.
The study therefore does not say that exercising for three minutes is sufficient in itself for all health goals. The finding concerns behaviour and total exercise time within this study design. The researchers did not measure long-term effects on, for example, fitness, weight or disease risk.
The research was peer-reviewed and published as an article in the journal Behavioral Medicine. The authors describe it as evidence of the potential value of small goals in building habits. Because the study lasted only three weeks and the participants reported their own behaviour, caution is still needed when applying the finding to the population as a whole.
The finding is consistent with earlier research into short bouts of physical activity, but its precise value depends on the intensity, total duration and health of the participant. A short daily activity can be a step towards becoming more active, but the study did not examine whether all forms of three-minute activity produce the same outcome.
The main significance of the research therefore lies in the behavioural strategy: a goal small enough to repeat every day may produce more total activity than a more ambitious goal that is carried out less often. That is an indication for prevention programmes, not an individual medical prescription.

Editor's note
This is a peer-reviewed study with 142 participants and a three-week follow-up. The study measures more exercise time and feasibility, not long-term health directly; that distinction has been made in the article.Sources
