Figure 45 – Removing Date and Time Filters

Energy Expenditure

Energy expenditure in kilo-calories (kcals) can be calculated quickly and easily by adding datasets to the “Data Scoring”

tab, entering the subject’s weight (in lbs.), selecting “Worn on Wrist” (if applicable), and clicking “Calculate Energy

Expenditure.” Each dataset kcal value will be summed and reported alongside the corresponding dataset. A summed

total will appear at the bottom of the grid for the entire dataset group.

The “Use cleaned data if available” box is selected by default. This setting enables data scoring only on filtered data and

excludes invalid data (based on data filtered in the “Wear Time Validation” tool).. Deselecting this option performs data

scoring on the entire dataset or group of datasets regardless of validation results.

Energy Expenditure Algorithms

Four algorithm options are available to users.

• Work-Energy Theorem. This formula utilizes the physics equivalent of energy

 =  × 0.0000191 × 
