Summary
Globally, 9.2 million less cases of dementia could result from delaying it by as little as 12 months. We will assess the impact, on artery health and cognition, of a novel exercise intervention involving enhanced patterns of brain blood flow and arterial shear stress during exercise, stimuli which should optimise cerebrovascular health. Given that pharmacological approaches to prevention are ineffective, this project has the potential to address the future impact of this common and debilitating ....Globally, 9.2 million less cases of dementia could result from delaying it by as little as 12 months.

Summary
Heart failure (HF) is a common, debilitating and expensive disease; prognosis remains poorer than for the most cancers. 30,000 Australians are diagnosed every year and 300,000 live with the HF, at an annual cost of ~$1Billion. Exercise training is effective therapy in HF, because it reverses many of the problems that contribute to the reduced lifespan and impaired quality of life of patients with HF. We will test an exciting new type of exercise that promising greater benefit, at lower risk.
Does Exercise Increase Skeletal Muscle Insulin Sensitivity Via Nitric Oxide?

Summary
Almost one in four Australian adults have either diabetes or impaired glucose metabolism. A major benefit of exercise is that it increases the sensitivity of muscle to insulin for many hours after the exercise is completed. We don't fully understand the mechanisms that exercise increases muscle insulin sensitivity. If we discover how nitric oxide production during exercise is involved, drugs that mimic these exercise effects may be designed to benefit those with diabetes.
