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.
