Figure 2. From: Validity of Physical Activity Intensity Predictions by ActiGraph, Actical, and RT3 Accelerometers.

Percent of study spent in four intensity classes represented as the difference from the calorimeter. AC, Actical; AG, ActiGraph; METs, metabolic equivalents.

Figure 1. From: Validity of Physical Activity Intensity Predictions by ActiGraph, Actical, and RT3 Accelerometers.

Difference in PAL predicted with each regression equation and the measurement using the calorimeter. Underpredictions fall below the x-axis, while overpredictions are above. The mean PAL measured by the calorimeter is 1.40. AC, Actical; AG, ActiGraph; PAL, physical activity level.
