Calibration of the global physical activity questionnaire to Accelerometry measured physical activity and sedentary behavior

Table 3 Proportion of Variance Explained for the Outcome-Matching Models and the Proposed Calibration Models

Outcome	R² for Outcome-Matching Model	R² for Final Calibration Model

Moderate-intensity PA	0.144	0.341
Vigorous-intensity PA	0.177	0.364
MVPA	0.156	0.282

PA = physical activity; MVPA = moderate- and vigorous-intensity physical activity
