Effectivness of Active Office Intervention

Study Overview
=================
Brief Summary
-----------------
The Active Office study is focusing on interventions with potential to reduce sedentary behavior and increase physical activity in office workers. The participants will be devided in two groups, the experimental and the control group. The participants in the experimental group will use active office (sit-to-stand desk, bike desk, seddle chair and active breaks) for one week, whereas the control group will remain in the conventional sitting-desk office. All the participants will wear ActivePal for 5 consecutive day and complete the measurements (heart rate, blood pressure). The goal of the study is to evaluate the effects of active office on sedentary behavior and physical activity levels in office workers.

Detailed Description
-----------------
Sedentary behavior is racognised as an independent risk factor for the development of non-communicable diseases. It is estimated that office workers spent up to 80 % of their working time sedentary and do not compensate by sitting less in their leisure time. Therefore, interventions with potential to reduce sedentary behavior and increase phyical activity levels are of increasing interest. The aim of this study is to evaluate the effects of active office, including sit-to-stand desk, bike desk, seddle chair, and active breaks, on sedentary behavior, physical activity levels, and cardio-vascular parameters. The study design will be randomised control trial with one experimental and one control group. The participants in the experimental group will use active office for one week whereas the control group will use the conventional office. All the participants will wear ActivePal for 5 consecutive day and complete the measurements (heart rate, blood pressure). The participants will also complete quastionaires about the sedentary behavior and physical activity levels (Sedentary Behavior Questionnaire, Global Physical Activity Questionnaire). Moreover, at the baseline and on the last day of measurements the investigators will measure the work environment factors (light, noise, air flow, temperature). The goal of the study is to evaluate the effects of active office on sedentary behavior and physical activity levels in office workers.
