Applied sports nutrition assists athletes in improving performance through the tailored manipulation of nutrient intake and timing. It requires an in-depth understanding of the science supporting the fields of general and sports nutrition, exercise physiology, sports science, and health science. It also requires practitioners like sports dietitians to have an understanding of the issues that influence an athlete’s daily food and fluid intake in order to convert the science of sports nutrition into practical solutions easily incorporated into the everyday diet of athletes and active individuals. In Australia, sports dietitians play a key role in the preparation and education of athletes, coaches and other sports science and sports medicine staff. Sports Dietitians Australia’s is the peak organisation for sports dietitians, and is dedicated to inspiring, educating and empowering sports dietitians to be world leaders in sports nutrition practice. As sports nutrition becomes a more recognised sports science discipline it is imperative that sports dietitians maintain and/or achieve the highest level of training and accreditation. Sports Dietitians Australia is in the process of developing a multi-level career education pathway for accreditation of sports Dietitians in Australia. The proposed pathway requires dietitians to achieve practical experience in the delivery of sports nutrition advice and undertake professional learning in areas relating to sports nutrition. The pathway has been designed to ensure recognition of varying levels of qualifications and experience currently within the sports dietetics community. While providing members with direction and ensuring they strive to attain the highest level of qualification within the sports nutrition community in Australia.

INVITED Asics supported speaker Valgus foot wedging for knee osteoarthritis C. Payne1* 1 Department Of Podiatry, LaTrobe University
Knee osteoarthritis (OA) affects 30% of people over 65 years, imposing significant pain, physical disability and a significant personal, societal and economic burden cost. Management usually focuses on pain reduction that attempts to optimise physical function. Surgical management is usually used in later stages of the disease process after failure of conservative treatments have not been successful. Drug interventions have been shown to be effective, but can be associated with adverse effects. In light of this non-pharmacologic measures are considered the important in the management of knee OA. As higher knee adduction moments and varus malignment are associated medial knee OA, laterally or valgus wedged insoles are strategy non-pharmacological strategy that is recommended for its management. Reductions in the peak adduction moment of around 10-15% are generally reported. Case series and limited controlled trials report decreases in pain of up to 50-80%, but the results tend to be inconsistent. It also appears that the biomechanical and symptomatic effects of lateral foot wedging may be subject specific, so sub-group analyses have not been completed yet and the larger more definitive studies have not yet been completed. Also of concern is the potential effect of lateral foot wedging on foot function. No outcome study on the use of lateral foot wedging for knee OA has reported any problems occurring with foot symptoms as a result of the wedges.

SYMPOSIUM Correlates and consequences of sedentary behaviour: findings from the PLACE study D. Crawford1*, E. Leslie2, C. Vandelanotte3, P. Gardener3 & T. Sugiyama3 1 School of Exercise and Nutrition Sciences, Deakin University 2 School of Health & Social Development, Deakin University 3 School Of Population Health, Cancer Prevention Research Centre, The University of Queensland
The aim of this symposium is to present data from the Physical Activity in Localities and Community Environments study (PLACE) that relate to sedentary behaviours. Sedentary behaviours such as TV viewing or Internet use are becoming increasingly more common. These behaviours have the potential to displace or reduce physical activity and are associated with negative health consequences, such as an increased BMI and abnormal glucose metabolism. It is important to have more insight into the correlates and consequences of sedentary behaviours, as they will inform us how to design and develop new interventions (individual or environmental) that promote a healthy lifestyle with being less sedentary and more active. For such purposes, data from the PLACE study, with a large and varied sample of participants (n=2650) from metropolitan Adelaide, provide excellent opportunities to describe these sedentary behaviours, their correlates and implications. The first paper will introduce the aims and methodology of PLACE and will briefly touch on the main outcomes of the study. The second paper will investigate the associations between leisure-time computer and Internet use with BMI and physical activity. The third paper will examine the correlates of TV viewing in older adults. The fourth paper will evaluate whether physical activity or sedentary behaviour is a stronger predictor of BMI. Following these presentations the Chair of the symposium Professor David Crawford will act as discussant and will critically summarise the presented research and engage the audience into a discussion.

Introduction to the aims, methods and main outcomes of the PLACE study To set the scene for a symposium, the aims, methods and main outcomes of the PLACE (Physical Activity in Localities and Community Environments) study will be introduced. Although the primary aim of PLACE was to evaluate links between levels of physical activity and the environment, it also provides data for the examination of other behaviours related to physical activity, but not directly related to the environment. The PLACE study used a stratified sample design to categorise 32 communities in Adelaide, classified as high or low ‘walkable’ using objective measures of connectedness and proximity derived from Geographic Information Systems and matched for area-level socio-economic status (SES). Surveys were mailed to participants between July 2003 and June 2004. The primary physical activity variables examined were walking for transport and recreation. Analyses controlled for participant age, gender, SES, and reasons for neighbourhood self-selection. A strong independent association was found between weekly frequency of walking for transport and objectively derived neighbourhood walkability. Neighbourhood self-selection was a moderator of the relationship of walkability with weekly minutes, but not with frequency of walking for transport. There were no significant associations between environmental factors and walking for recreation. Associations of neighbourhood environment attributes with walking for transport were confirmed, supporting design for activity-friendly communities. The rich source of data in PLACE can also be used to better understand other health122related behaviours which may coexist or compete with physical activity. Subsequent presentations in this symposium will use this data to examine the correlates and consequences of sedentary behaviours.
