Influence of athletic footwear on lower limb biomechanics of pubertal girls. This project aims to determine whether athletic footwear with appropriate design features can help improve neuromuscular control and, in doing so, reduce the potentially deleterious forces on the knee and lower limb structures of pubertal girls. As girls reach puberty, they become less able to control the movement patterns of their lower limbs, particularly in high-demand tasks like running and jumping. Better-designed ....Influence of athletic footwear on lower limb biomechanics of pubertal girls. This project aims to determine whether athletic footwear with appropriate design features can help improve neuromuscular control and, in doing so, reduce the potentially deleterious forces on the knee and lower limb structures of pubertal girls. As girls reach puberty, they become less able to control the movement patterns of their lower limbs, particularly in high-demand tasks like running and jumping. Better-designed footwear for pubertal girls may improve movement patterns, decrease the likelihood of musculoskeletal injury and improve physical activity participation rates. Project outcomes may lead to the development of such footwear, and are also anticipated to expand our understanding of female developmental biomechanics.Read moreRead less
Athletic footwear for reducing knee loads in girls and women. This project aims to develop a novel athletic shoe that can reduce harmful knee loads during sport in adolescent girls and young women. As girls reach puberty, they become less able to control the movement patterns of their knees and lower limbs - particularly in high-demand tasks like jumping. The project will develop a new ASICS shoe that will be ‘field-tested’ during sporting activity with high ACL injury risk (netball) to evaluate ....Athletic footwear for reducing knee loads in girls and women. This project aims to develop a novel athletic shoe that can reduce harmful knee loads during sport in adolescent girls and young women. As girls reach puberty, they become less able to control the movement patterns of their knees and lower limbs - particularly in high-demand tasks like jumping. The project will develop a new ASICS shoe that will be ‘field-tested’ during sporting activity with high ACL injury risk (netball) to evaluate its effect on tibial shock (in-field surrogate measure of knee load) and player comfort compared to a conventional shoe. Expected outcomes include reduced healthcare costs associated with the treatment of serious knee injury, including surgical reconstruction and early-onset knee osteoarthritis.Read moreRead less
Understanding influences on physical activity and sedentary behaviour from preschool to preadolescence. While promotion of optimal levels of physical activity and sedentary behaviours during childhood is important for health, much remains unknown in this field. This study will extend an existing cohort of children, recruited at ages three to five years and followed up at six to eight years by reassessing these children at nine to eleven years. Novel additions to the cohort include long term foll ....Understanding influences on physical activity and sedentary behaviour from preschool to preadolescence. While promotion of optimal levels of physical activity and sedentary behaviours during childhood is important for health, much remains unknown in this field. This study will extend an existing cohort of children, recruited at ages three to five years and followed up at six to eight years by reassessing these children at nine to eleven years. Novel additions to the cohort include long term follow-up spanning preschool to preadolescence, application of an ecological framework, and collection of objective neighbourhood data using a Geographical Information System. Findings will provide important information for policy and interventions focused at the individual, family and neighbourhood level, to improve physical activity and sedentary behaviour levels across childhood.Read moreRead less
Providing children with a healthy start to life: promoting physical activity and reducing sedentary behaviours during early childhood. Early childhood (0-5 yrs), when health behaviours develop and may track into later life, represents promise as a time to positively impact physical activity and sedentary behaviour. Yet study of these behaviours in 3-5 yr olds is only emerging, and is almost non-existent in younger children. This project aims to understand predictors of these behaviours using a s ....Providing children with a healthy start to life: promoting physical activity and reducing sedentary behaviours during early childhood. Early childhood (0-5 yrs), when health behaviours develop and may track into later life, represents promise as a time to positively impact physical activity and sedentary behaviour. Yet study of these behaviours in 3-5 yr olds is only emerging, and is almost non-existent in younger children. This project aims to understand predictors of these behaviours using a suite of longitudinal studies, including objective measures, and will commence as early as 3-mths of age. It will study strategies for promoting physical activity and reducing sedentary behaviours during early childhood, by investigating mechanisms of behaviour change in existing interventions to inform new strategies with potential to provide children with a healthy start to life.Read moreRead less
Improving determinants of Australian sports talent identification and development: a multi-disciplinary approach. Sport is important to many Australians. Our sport successes enhance our national identity, generate community pride and attract mega sport events.

Sport is important to many Australians. Our sport successes enhance our national identity, generate community pride and attract mega sport events. Currently our sport talent identification and development (TID) systems have been surpassed by our international rivals who borrowed from and improved our knowledge. This project will help regain Australia's international advantage and again make Australian TID the international benchmark. Results will highlight the role of TID practices in improving recreational participation and maximising, attracting, developing and retaining sport talent. This will result in improved use of sports limited TID funding by providing greater understanding of factors that influence elite selection and sport development.Read moreRead less
Biological Role of Contraction-Induced Heat Shock Protein Expression. It is well known that mammalian skeletal muscle increases its expression of a group of highly conserved proteins, the heat shock proteins (HSP) in response to repeated contraction. However, the biological role of this expression is unclear. The aim of this project is to determine the biological role of contraction-induced HSP expression. We expect to show that HSP synthesis in response to exercise has three major roles; 1) to ....Biological Role of Contraction-Induced Heat Shock Protein Expression. It is well known that mammalian skeletal muscle increases its expression of a group of highly conserved proteins, the heat shock proteins (HSP) in response to repeated contraction. However, the biological role of this expression is unclear. The aim of this project is to determine the biological role of contraction-induced HSP expression. We expect to show that HSP synthesis in response to exercise has three major roles; 1) to act to repair damaged proteins in recovery from muscle injury 2) to act as a "molecular motor" to translocate proteins from one region of a muscle cell to another and 3) to be released into the circulation in order to act as a central signal to activate immune cells. Such a project will be significant because it will allow for a fundamental understanding as to why these proteins are produced in response to exercise. We expect to enhance our understanding of fundamental cell biology.Read moreRead less
Discovering the role of pH in regulating mitochondrial biogenesis, so as to improve the design of preventative programs aimed at healthy ageing. Mitochondria are essential for life, and maintaining mitochondrial function plays an important role in preventing the progression of many age-related diseases. It has previously been shown that minimising the decrease in muscle pH that occurs during physical activity promotes greater improvements in mitochondrial function. The next step is to discover t ....Discovering the role of pH in regulating mitochondrial biogenesis, so as to improve the design of preventative programs aimed at healthy ageing. Mitochondria are essential for life, and maintaining mitochondrial function plays an important role in preventing the progression of many age-related diseases. It has previously been shown that minimising the decrease in muscle pH that occurs during physical activity promotes greater improvements in mitochondrial function. The next step is to discover the effects of altering pH on acute and chronic activity-induced changes in signalling proteins and genes that are involved in the regulation of skeletal muscle mitochondrial biogenesis. These experiments will significantly advance the knowledge base concerning factors regulating mitochondrial biogenesis, and will contribute to optimising the design of preventative programs aimed at healthy aging.Read moreRead less
Evaluating the impact of obesity on knee load over time in those who have undergone optimal surgical re-alignment after total knee replacement . This project investigates the impact of obesity on alignment and knee load over time in those who have undergone total knee replacement. This information is critical for understanding whether obesity results in increasing knee load after surgery which can lead to more rapid wearing of the knee surfaces and an earlier need for revision surgery.
A Wearable Motion Analysis System: Novel Clinical and Research Applications. Because the biomechanical analysis of human motion is confined to the laboratory, it often has restricted applicability. This is a recognized limitation, because laboratory studies cannot capture the true picture of how individuals move under conditions encountered during daily living. Consequently there are many situations where a more complete and realistic knowledge of biomechanics would be significant advantage such ....A Wearable Motion Analysis System: Novel Clinical and Research Applications. Because the biomechanical analysis of human motion is confined to the laboratory, it often has restricted applicability. This is a recognized limitation, because laboratory studies cannot capture the true picture of how individuals move under conditions encountered during daily living. Consequently there are many situations where a more complete and realistic knowledge of biomechanics would be significant advantage such as in the diagnosis, treatment and rehabilitation of movement disorders and injuries. The research project described in this proposal would for the first time, obtain comprehensive biomechanical data outside the laboratory using a fully integrated wearable motion analysis system.Read moreRead less
Optimising Exercise and Nutrition Throughout the Life Cycle. During the past decade the proportion of Australia's population aged 65 years and over has increased to 13% (2.7 million). During the same period, the proportion of the population aged 85 years and over has more than doubled and is now the fastest growing subpopulation in Australia. As the number of elderly persons continues to grow, sarcopenia-related conditions will have a dramatic and inevitable impact on the lives of all Australian ....Optimising Exercise and Nutrition Throughout the Life Cycle.

During the same period, the proportion of the population aged 85 years and over has more than doubled and is now the fastest growing subpopulation in Australia. As the number of elderly persons continues to grow, sarcopenia-related conditions will have a dramatic and inevitable impact on the lives of all Australians. The novel dietary protocols developed from the results of the studies undertaken in this proposal will translate into better treatment options for reversing age-dependent muscle degeneration. This is a critical first step for improving the standard of living for a large portion of Australian society.Read moreRead less
