Summary
Participation in regular moderate to vigorous intensity physical activity reduces risk for cardiovascular disease, non-insulin dependent diabetes, osteoporosis and some cancers. Recent epidemiological recommendations are that 30 minutes of moderate intensity physical activity (e.g. brisk walking at 4.8-6.4 km-hr) on most days is sufficient to confer these significant health benefits. However, many Australians spend substantial amounts of time engaged in household chores and gardening - yardwork ....Participation in regular moderate to vigorous intensity physical activity reduces risk for cardiovascular disease, non-insulin dependent diabetes, osteoporosis and some cancers. Recent epidemiological recommendations are that 30 minutes of moderate intensity physical activity (e.g. brisk walking at 4.8-6.4 km-hr) on most days is sufficient to confer these significant health benefits. However, many Australians spend substantial amounts of time engaged in household chores and gardening - yardwork activities but it is unknown whether the intensities of these activities are sufficient to confer the aforementioned health benefits. The aims of this study are therefore to: 1. Measure directly the energy cost of self-paced common household chores and gardening - yard activities. 2. Provide data that are required to estimate accurately the prevalence of 'adequate' levels of physical activity among adults. 3. Identify indirect methods (such as heart rate, motion and breathing frequency) which, in combination, are suitable for use in large scale surveys of activity levels. The outcomes of this study will be: 1. A greatly improved understanding of whether energy expenditure associated with self-paced household chores and gardening - yard activities is adequate to confer health benefits. 2. Our results will be used in key public health interventions which are aimed at modifying the physical activity levels of Australians. 3. If the public health message encourages some of the ~30% of sedentary Australians to undertake regular moderate intensity physical activity then this will: reduce the cost of the health care system, substantially reduce the premature loss of life and decrease morbidity and disability. 4. Our results will help public health epidemiologists to monitor the percentage of Australians who are adequately physically active.Read moreRead less
A Multicentre Randomised Clinical Trial Of Physical Activity For The Treatment Of Patients With Alzheimers Disease

Summary
The number of older adults living with Alzheimer's disease (AD) will increase from 26.6 million to 106.2 million by 2050. In the absence of curative treatment options it is important to focus on non-pharmacological interventions such as physical activity. We propose to investigate whether a home-based physical activity program of 24 weeks for patients with AD can successfully decrease the rate of cognitive and functional declince and improve quality of life and psychological well-being.
Studies Of Metabolites Of Synthetic Flavonols For The Treatment Of Cardiovascular Disease

Summary
Cardiovascular disease, including heart attack and stroke, is the leading killer of Australians. A promising new drug, NP202, can reduce the amount of tissue damaged from a heart attack; however, its mechanism of action remains obscure. NP202 is metabolized to a range of compounds, one of which is partly responsible for its beneficial effects. In this project we will identify other metabolites of NP202 and characterize their biological activity to gain insight into its mechanism of action.
Physical Activity Coaching For Adults With Physical Disabilities: A Pragmatic Randomised Controlled Trial.

Funding Amount
$1,371,185.00
Summary
People with impaired mobility can achieve substantial benefits from appropriate physical activities but face many barriers to being active so require targeted interventions and health professional support. This trial (n=600) will test the effectiveness and cost-effectiveness of an enhanced physical activity coaching intervention (home-visit from a physiotherapist, phone coaching, technology) with phone coaching alone and with no intervention.
