Summary
This research aims to define trends in the prevalence of, and complications associated with, metabolic syndrome in adults with type 1 diabetes, using the Australian National Diabetes Information Audit and Benchmarking Initiative (ANDIAB). Subsequently, a randomised controlled trial will examine the effect of exercise on glycaemic control and diabetes complications risk profiles in this group. These studies will thus address disease profiles and a potential beneficial clinical intervention.
Nutrient And Hormone Delivery To Muscle: Interactions Between Insulin And Exercise

Summary
Exercise is known to be beneficial in the treatment and prevention of Type 2 diabetes and in particular muscle insulin resistance. Also, exercise and insulin share similar acute actions on muscle. Firstly, muscle contraction has a well established action to increase glucose uptake, and secondly, both muscle contraction and insulin act to increase capillary recruitment. This latter phenomenon is thought to enhance nutrient delivery and waste product removal. There is evidence that the increase in ....Exercise is known to be beneficial in the treatment and prevention of Type 2 diabetes and in particular muscle insulin resistance. Also, exercise and insulin share similar acute actions on muscle. Firstly, muscle contraction has a well established action to increase glucose uptake, and secondly, both muscle contraction and insulin act to increase capillary recruitment. This latter phenomenon is thought to enhance nutrient delivery and waste product removal. There is evidence that the increase in capillary flow due to muscle contraction is accompanied by increases in total blood flow. For insulin action we now have preliminary data to indicate that capillary recruitment occurs within a 5-10 min application of a physiologic dose of insulin independent of a change in total blood flow suggesting a redistribution of flow. Muscle contraction also increases capillary recruitment and it raises the question of whether similar mechanisms underlie insulin- and muscle contraction-induced capillary recruitment or whether there are distinct and complementary pathways. In this project we plan to define the mechanisms responsible for contraction- and insulin-induced capillary recruitment in muscle. We hypothesize that similar mechanisms are operative, with both insulin and muscle contractions acting via NO-dependent mechanisms. Because of capillary reserve, and different initial steps of the signalling systems stimulated by insulin and exercise, capillary recruitment by combined contraction and insulin stimuli will be additive at both sub maximal and perhaps at maximal insulin pathway stimulation. Signalling mechanisms will be compared and the role of non-nutritive route as a flow reserve assessed.Read moreRead less

Summary
The PREVIEW Study will identify the most efficient lifestyle pattern for the prevention of type-2 diabetes in a population of pre-diabetic overweight or obese individuals. The project comprises two distinct lines of evidence, an intervention study and population studies. The focus will be on diet (specifically protein and glycemic index) and intensity of physical activity, as well as their interaction with the lifestyle factors, habitual stress, sleeping pattern, behavioural, environmental, cult ....The PREVIEW Study will identify the most efficient lifestyle pattern for the prevention of type-2 diabetes in a population of pre-diabetic overweight or obese individuals.

Funding Amount
$122,686.00
Summary
This research aims to analyse newly proposed treatment targets for Gestational Diabetes Mellitus (GDM) and the effect this will have on maternal and child health outcomes, via comparison of data from two large Australian health services using the traditional and newly proposed critiera. The research will also investigate current effective interventions for GDM, including the impact of early antenatal lifestyle interventions, and formulation of a clinical and biochemical risk prediction model.
Can Exercise Early After Spinal Cord Injury Prevent Deterioration Of Muscle And Bone?

Funding Amount

Summary
Spinal cord injury leads to a profound deterioration of the muscles and bones in the paralysed limbs. This project will examine the effects of exercising the paralysed limbs as early as possible after injury to prevent muscle and bone loss rather than restoring the tissues once changes have occurred. The time course and mechanisms underlying the microstructural decay of bone over the first year after injury will also be examined to provide a basis for determining fracture risk in this group.
A Multi-ethnic Cohort And Intervention Trial To Identify Early Biomarkers For Type 2 Diabetes And Customise Individualized Environments For Disease Prevention

Funding Amount
$597,376.00
Summary
Diabetes is often called a lifestyle disease, however, large clinical studies have shown that diabetes cannot always be prevented through lifestyle modification. This collaborative study between Shanghai Institutes of Biological Science and Sydney University will identify biomarkers that predict the development of type 2 diabetes. Using this knowledge, the best interventions (including diet, exercise and medications) to improve an individual’s risk profile for type 2 diabetes will be identified.
Gastric Counter-regulation Of Hypoglycaemia: Studies In Health And Diabetes

Funding Amount

Summary
Insulin injections are often needed to treat diabetes, but they can cause low blood sugar levels (hypoglycaemia), which are usually distressing, and sometimes fatal. The stomach is important in regulating blood sugar; in response to hypoglycaemia, it empties food much more rapidly, allowing carbohydrate to be absorbed faster to normalise blood sugar levels. The proposed studies will explore this important area, in order to develop better ways of preventing and treating hypoglycaemia.
