Physical activity logs and accelerometers provide different estimates of moderate-to-vigorous physical activity (MVPA). Researchers should use caution when comparing MVPA intervention outcomes measured by different methods.

Area of Science:

  • Exercise Science
  • Biomedical Engineering
  • Health Informatics

Background:

  • Accurate measurement of physical activity (PA) is crucial for evaluating interventions.
  • Discrepancies exist between self-reported PA and objective measures like accelerometers.
  • Understanding these differences is key for reliable intervention outcome assessment.

Purpose of the Study:

  • To compare moderate-to-vigorous physical activity (MVPA) estimates from accelerometers and technology-supported PA logs.
  • To analyze changes in MVPA measurement agreement over a 3-week intervention.
  • To assess the impact of different measurement methods on intervention effect sizes.

Main Methods:

  • 204 participants (77% female, age 33 ± 11) were randomized to an MVPA increase or active control group.

  • Participants wore accelerometers and completed daily PA logs for 5 weeks (2-week baseline, 3-week intervention).
  • Bivariate linear mixed-effects models and correlations analyzed MVPA relationships; effect sizes were calculated.

    • Main Results:

    • At baseline, PA logs overestimated MVPA by 28 minutes in the active control group.
    • The MVPA intervention group showed a 35-minute greater difference between PA log and accelerometer at follow-up vs. baseline.
    • Intervention effect sizes differed significantly: 0.27 for PA log vs. 0.42 for accelerometer.

    Conclusions:

    • Accelerometer and PA log MVPA estimates significantly differ in daily minutes.
    • Researchers must exercise caution when comparing intervention outcomes derived from disparate PA measurement methods.
    • Standardizing measurement tools is essential for consistent and valid research findings.
