Physical activity (PA) can have positive health outcomes for children with type 1 diabetes (T1DM) such as improved diabetes control, lipid profile and body composition, yet activity levels are low. The unpredictable nature of children's everyday activity causes fluctuations in blood glucose (BG) level. Low and high BG level are side-effects of PA, have significant symptoms and can cause a range of chronic complications. Parents typically have responsibility for diabetes management in preadolescent children and perceive PA as a challenge due to constant concerns about BG levels (Quirk et al., 2015).
