Are we as active as we think?

For many health-conscious individuals, tracking physical activity is a key part of daily life. However, when people are asked to self-report their physical activity, their estimates often depart significantly from reality.

A recent study by a sports science institute investigated this gap by comparing participants' self-reported physical activity with objective data collected from medical-grade wrist-worn accelerometers.

The findings showed:

• When asked to estimate their daily duration of moderate-to-vigorous physical activity (MVPA), 82% of participants overestimated their daily activity by more than 45 minutes.
• Additionally, 70% of participants self-reported that they achieved the recommended 150 minutes of moderate activity per week. However, the objective accelerometer data revealed that only 28% of these individuals actually met this threshold, with the majority averaging just 85 minutes per week.

This demonstrates that subjective self-reports of physical activity can be highly unreliable when compared to precise, objective measurements.
