Abstract

Boutlength is an open program developed in a spreadsheet environment to identify and display activity bout lengths derived from accelerometer count data. The program classifies counts into an active or inactive level based on user-defined cut-off thresholds. Using a bout qualification criterion specified by a minimum length, the program identifies, prints, sorts, and computes basic statistics on resulting valid bout string. The program was tested on a sample of actual database using cut-off values (Sedentary: < 100 counts; Activity: > 2019 counts) and bout qualification criteria (Sedentary: ≥ 5 minutes; Activity: ≥ 2 minutes). Output of the program is a display of identified Sedentary or Activity bouts depending on the application. Program’s parameters are modifiable, and the script was designed in a spreadsheet software. Boutlength is still in development and yet it may be an interesting resource for researchers analysing bout-based physical activity pattern measures.
