Exercise-stimulated glucose uptake — regulation and implications for glycaemic control
Physical activity is one way to enhance insulin sensitivity and manage blood sugar for those with insulin resistance or diabetes. According to research exercise can be used as therapy for those with diabetes - as glucose control is managed independently of the effects of insulin. 
Recent research conducted by the University of Copenhagen and published in the journal Nature, involves understanding how glucose metabolism is regulated with a focus on skeletal muscle.
Key points from this study: 
glucose metabolism can be restored (even in insulin resistant muscle) for up to 48 hours after exercise.
glucose uptake by skeletal muscle can increase by up to 50-fold during exercise.
long-term exercise training improves the effect of insulin on glucose uptake in muscle at rest.
Diet is often viewed as the primary intervention for managing insulin resistance and metabolic syndrome  but the combination of diet and physical activity is even more powerful especially when you consider insulin is not even required to manage blood glucose (when physically active) . Movement is medicine.
Engaging in functional fitness training exercises, such as Primal Play, will help you manage blood glucose through appropriate physical activity.
