Levels of Daily Physical Activity and Sedentary Behaviour in Maastricht University's Undergraduate First Year Students

Maastricht University First Year Students

Maastricht University 2017-2018 undergraduate first year students are invited to participate in the study. The participants are invited to complete a demographics questionnaire, wear an ActivPAL accelerometer for 7 days, and to complete daily diaries (modified International Physical Activity Questionnaire) for 7 days.

Otro: No intervention

No intervention is given to the participants. This is an observational study exploring the students' levels of physical activity and sedentary behaviour in their natural setting.

Time (minutes) spent in various activities (sleeping, being sedentary, standing and stepping) measured by the ActivPAL accelerometer

The ActivPAL accelerometer senses limb position and activity. From this information, it can reliably discriminate periods of upright activity from seated or lying activities. Furthermore, the cadence (stepping rate) of upright activities can be accurately recorded. Energy expenditure (estimated by the ActivPAL accelerometer using Metabolic Equivalent of Task (MET)) and cadence (step frequency, i.e., steps per minute) will be used to distinguish between sleeping, being sedentary, standing and stepping. The time spent sleeping, being sedentary, standing and stepping will be measured and compared against global recommendations of physical activity (e.g., WHO recommendations).
