Description of activity categories

Background:

Data is analysed using an algorithm and categorised into different activity categories, as shown in this article.

Activity categories:

Data are analysed in 5 second intervals and each interval is estimated to belong to a specific activity category.

Different types of physical activity are distinguished and displayed in different colours:

No data; No data collected.

Lying/sitting rest; The participant sits or lies down with little or no movement.

Lying/sitting movement; Movements of the participant in a lying or sitting state.

Standing; The participant stands upright.

Walking; The participant walks continuously.

Sporadic walking; The participant stands upright, but with a few movements. The activity relates to 'Standing' and 'Walking', but is a middle ground and irregular.

Cycling & similar; The participant cycles.

Moderate intensity; The participant is in a brisk walk, where the activity is higher than 'Walking', but lower than 'High intensity'.

High intensity; The participant runs.

Each bar in the graph represents 15 minutes. The activity categories are represented in the graph vertically with colours depending on the type of activity.
