We spend most of our day sitting. Sitting has been associated with increased risk of diseases such as diabetes but performing regular activity breaks (~2 min of activity every 30 min) throughout the day can help to reduce this risk. However, we don’t know if performing regular activity breaks in the evening has the same effects despite the fact that in the evening we often eat a large meal, and then sit for long periods watching Netflix. Long periods of screen time can negatively impact on sleep. Thirty participants will visit the lab in the evening on two occasions. On one occasion they will sit and watch Netflix uninterrupted for 4 hours, on the other they will perform simple resistance exercises for 3 min every 30 min. The effects on blood glucose, insulin and triglyceride levels after eating dinner, and the effects on sleep quality that evening will be compared.
