Evaluation of a sedentary time fractionation intervention for adult home-based workers – Aidan Buffey

There is a strong evidence base linking prolonged bouts of sitting with an increased risk of conditions such as type-2 diabetes and cardiovascular disease.  It is possible that individuals working from home may be sitting for longer continuous periods of time than office-based workers.

This study will initially use a thigh-worn activity monitor device to record the physical activity and sedentary time (this is the time spent sitting or in a reclined position with a low energy expenditure) of adults who are working from home. After three weeks of wearing the physical activity monitor, we will implement a home-based sedentary time fractionation intervention program. This program is designed to interrupt periods of continued sitting every 45 minutes with five minutes of light-intensity walking which will be completed for three weeks during working hours, such as Monday to Friday, 9am to 5pm.

The overall aim of this study is to determine whether it is feasible to break up people’s sitting time in this way as an intervention for health.

Aidan BuffeyAidan Buffey is a PhD student in the Department of Physical Education and Sport Sciences. He is funded by the Health Research Institue and supervised by Prof. Alan Donnelly and Dr Brian Carson. Aidan is in the first year of his PhD project titled ‘Design and evaluation of an intervention to reduce sedentary behaviour and improve health in older adults’. This project aims to implement an office-based intervention designed to interrupt sedentary behaviour with light-intensity physical activity with an emphasis on improving cardiometabolic health markers. Aidan has an MSc in Sport and Exercise Science – Physiology (Manchester Metropolitan University, 2018-2019) and a BSc (Hons) Sport and Exercise Science (Manchester Metropolitan University, 2015-2018).  Contact Adian at Aidan.Buffey@ul.ie or follow him on @AidanBuffey .  Research profiles on LinkedIn or Researchgate on Orcid
