The role of exercise in promoting sleep and improving appetite regulation is being examined as part of a study at Charles Sturt University (CSU).Student Ms Penelope Larsen is completing her PhD through the CSU School of Exercise Science, Sport and Health and needs more than 600 people aged between 35 and 60 to take part in her research."The first component of the study uses a series of questionnaires which allow participants to give an explanation of their perceived sleep quality, eating behaviour, level of physical activity, and mood states," Ms Larsen said."Data from these questionnaires will examine the relationship between sleep, diet and physical activity to better determine the role of exercise in day-to-day lives."Participants can also volunteer to take part in further research where they could be randomly selected to wear an Actiwatch for two weeks to record daily activity and sleep patterns.Ms Larsen's research supervisor Dr Melissa Skein from CSU in Bathurst said, "The study will provide vital information about an individual's sleep and overall health and will be the platform for Penelope to examine specific exercise training protocols on sleep, appetite, and eating behaviour later in her PhD."The provision of questionnaires means it does not require too much time for the participants and they complete it at a time that suits them."If you have any questions or would like to take part in the research contact Ms Larsen by email to plarsen@csu.edu.au
