Adherence
Reporting error in self-reported physical activity energy expenditure is significantly predicted by gender, percent body fat, peak oxygen uptake, and the level of physical activity itself, with higher activity levels leading to greater underestimation.
Your fitness level and body composition affect how accurately you can estimate your activity. Highly fit individuals or those with higher body fat may systematically over- or underestimate their activity. If you are trying to self-report activity, be aware that your specific physiological profile may bias your recall.
In a regression model, PAEE, peak oxygen uptake, gender and percent fat accounted for 86% of the reporting error in total daily energy expenditure when using the 7D-PAR.
Why this rating
Strong regression model (86% variance explained) using gold-standard criterion.
