Exercise and Type 2 Diabetes Mellitus

Exercise is a crucial component of lifestyle therapy for both the prevention and management of type 2 diabetes (T2D). The aim of this chapter is to explain the various exercises implemented for the management of diabetic patients. These recommendations stem from strong evidence linking physical activity to a reduced risk of developing T2D, improved disease management, and lower diabetes-related morbidity and mortality. However, individuals with T2D face physiological and behavioral challenges that can hinder their ability to fully reap the benefits of physical activity. Physiological barriers include diabetes-related impairments in exercise capacity, higher perceived exertion at lower workloads, and the need for careful glycemic management during physical activity. Additionally, social and psychological factors, such as depression and low self-efficacy, can further discourage participation in exercise. Individual responses to physical activity can vary based on factors like sex, genetics, and environmental influences, making it difficult to predict the specific benefits for each person. The optimal exercise dosage, duration, timing, and type for maximizing health outcomes remain unclear. Both aerobic and resistance training enhance insulin action, at least in the short term, and can aid in managing blood glucose levels, lipids, blood pressure, cardiovascular risk, mortality, and overall quality of life. However, to sustain these benefits, exercise must be performed consistently and should ideally incorporate a variety of training types.
