Insulin is a key hormone in energy metabolism and blood sugar regulation. Normal insulin function in the body may be disturbed by e.g. overweight, leading to decreased insulin sensitivity and increased risk of developing type 2 diabetes and cardiovascular diseases. In a Finnish collaborative study of Turku PET Centre and UKK institute, the researchers noticed that standing is associated with better insulin sensitivity. Increasing the daily standing time may therefore help prevent chronic diseases.
Type 2 diabetes is one the most common lifestyle diseases worldwide, and its onset is usually preceded by impaired insulin sensitivity, i.e. insulin resistance. This refers to a state in which the body does not react to insulin normally, and the blood glucose levels rise.
Lifestyle has a strong impact on insulin resistance and the development of type 2 diabetes, and regular physical activity is known to have an important role in the prevention of these issues. However, so far, little is known about the impact of sedentary behaviour, breaks in sitting, and standing on insulin resistance.
In a study of Turku PET Centre and UKK institute, the researchers investigated the associations between insulin resistance and sedentary behaviour, physical activity and fitness in inactive working-age adults with an increased risk of developing type 2 diabetes and cardiovascular diseases. In the study published in Journal of Science and Medicine in Sport, the researchers observed that standing is associated with better insulin sensitivity independently of the amount of daily physical activity or sitting time, fitness level, or overweight.
