Web program increased older adults’ measured activity in a trial
A Dutch RCT found a web-based intervention raised daily activity ~46% and improved weight and HbA1c markers in inactive 60–70-year-olds.

Structured fields used in claim comparison tables when every cited study has a complete layer.
What they did
235 adults aged 60–70 near Leiden were randomized to a web-based physical-activity program or control; ankle/wrist accelerometers and metabolic measures were assessed over ~3 months.
What they found
Ankle-measured daily activity rose 46% vs 12% in controls; intervention lost more weight (−1.49 vs −0.82 kg) and had greater HbA1c decline.
The limits
What it doesn't show
Long-term maintenance beyond 3 months or effects in adults with established diabetes (excluded).
Key terms

- HbA1c
- Glycated hemoglobin reflecting average glucose.
- Metabolic health
- Markers such as weight, waist, insulin/HOMA, and HbA1c.
- Moderate-to-vigorous activity
- Higher-intensity activity minutes per day.
- Inactive older adults
- 60–70-year-olds targeted to increase activity.

Common questions
How much did ankle activity rise?
46% intervention vs 12% control after 13 weeks.
Who was recruited?
Adults 60–70 from the Leiden region, Netherlands.
How many were randomized?
235 (119 intervention, 116 control).
Did metabolism improve?
Yes—greater weight loss and HbA1c reduction versus control.
