Barriers to Exercise in Adults With Type 1 Diabetes and Insulin Resistance

Interrupting prolonged sitting with frequent short bouts of light‐intensity activity in people with type 1 diabetes improves glycaemic control without increasing hypoglycaemia: The SIT‐LESS randomised controlled trial

“…Within the context of type 1 diabetes (T1D), most individuals struggle to meet physical activity guidelines 10 and spend a greater proportion of time sedentary than people without T1D 11 . For example, a recent large cross‐sectional survey of 18 028 adults with T1D, reported that ~60% did not achieve recommended physical activity levels 10 a finding that supports some, 12–14 but not all previous studies 15 …”

“…Many people with T1D report fear of hypoglycaemia and an inability to manage their diabetes as major barriers to becoming active and engaging in regular moderate‐to‐vigorous physical activity participation, 14 yet, few mention this fear when asked about lower‐intensity activities such as walking 16 . Although many individuals with T1D do little‐to‐no exercise, they are often willing to increase participation in lower‐intensity physical activity and are keen to learn how to reduce sedentary behaviours 14,16,17 . However, little information is available for individuals with T1D or for the health care professionals who support them with regards to strategies for reducing sedentariness and their potential impact on hypoglycaemia risk 14,16,17 …”

Effects of 8 weeks of aerobic endurance training on functional capacity and metabolic variables in people with type 1 diabetes: A secondary outcome analysis of the ULTRAFLEXI‐1 study

“…Exercise is recommended as a cornerstone of T1D treatment. However, fear of hypoglycaemia and individual uncertainties related to proper insulin adjustment during exercise represent major barriers to physical activity for people with T1D 5,6 . However, previously published articles have shown that adjusted insulin management can reduce the risk of hypoglycaemia during physical activity and the associated risks while exercising 7–9 .…”

“…However, fear of hypoglycaemia and individual uncertainties related to proper insulin adjustment during exercise represent major barriers to physical activity for people with T1D. 5,6 However, previously published articles have shown that adjusted insulin management can reduce the risk of hypoglycaemia during physical activity and the associated risks while exercising. [7][8][9] Although studies have investigated the acute effects of different types and intensities of exercise 8,10 and their impact on blood glucose levels and insulin sensitivity, it is still unclear how duration, intensity, volume and type of sport in long-term continuous training programmes affect performance in people with T1D.…”
