Australia\u27s health 2006 : the tenth biennial report of the Australian Institute of Health and Welfare

The report shows that Australians generally have good health and are privileged to have a range of health care services available to them. There are stark exceptions to this that can be confronting&mdash;even if well-known already&mdash;notably the generally much poorer health status of Indigenous Australians.Health care service provider and funding arrangements are both increasingly complex and increasingly costly to both individuals and taxpayers. A continuing challenge is how to balance both the complementary and competitive perspectives of government and non-government agencies, professional groups, and small businesses. Overall, national expenditure on health was 9.7% of GDP in 2003&ndash;04; and average health expenditure per person has grown by an average 3.8% each year between 1997&ndash;98 to 2002&ndash;03. Expenditure on aids and appliances, health research and pharmaceuticals contributed more to this growth than other areas.While the ageing of the population is having a significant impact on the number and type of health care services delivered, high quality services for children continue to be a priority. Australia&rsquo;s health 2006 has a special chapter focusing on children and their health. The chapter highlights the fact that while our children are generally very healthy, there are concerns that their ongoing health could be affected by more and more of them becoming overweight or obese. Levels of diabetes are now rising among our children and it is a continuing concern that asthma and mental health problems affect so many of them.<br /

The effect of medical grade compression garments on the repeated-bout effect in non-resistance trained men

Whilst compression garments (CG) may enhance recovery from exercise-induced muscle damage (EIMD), many recovery strategies can attenuate adaptative responses. Therefore, the effects of CG on recovery from EIMD, and the rapid protective adaptations known as the repeated bout effect (RBE) were investigated. Thirty-four non-resistance trained males (18–45 y) randomly received class II medical-grade CG or placebo for 72 h following eccentrically-focused lower-body exercise, in a double-blind, randomised controlled trial. Indices of EIMD were assessed at baseline, 0, 24, 48 and 72 h post-exercise, before exercise and testing were repeated after 14 d. Results were analysed using a three-way (time x condition x bout) linear mixed-effects model. Exercise impaired isometric and isokinetic strength, with soreness and thigh circumference elevated for 72 h (p 0.05), despite small to moderate effect sizes (ES, reported alongside 90% confidence intervals) for isokinetic strength (ES from 0.2 [-0.41, 0.82] to 0.65 [0.03, 1.28]). All variables recovered faster after the repeated bout (p < 0.005). However, RBE for peak isokinetic force was impaired in CG at 60 ⁰.s-1 (group x bout interaction: χ2 = 4.24, p = 0.0395; ES = -0.56 [-1.18, 0.07]) and completely absent at 120 ⁰.s-1 (χ2 =16.2, p < 0.001, ES = -0.96 [-1.61, -0.32]) and 180 ⁰.s-1 (χ2 =10.4, p = 0.001, ES = -0.72 [-1.35, -0.09]). Compression blunted RBE at higher isokinetic velocities without improving recovery in non-resistance trained males, potentially contraindicating their use following unaccustomed exercise in this population

The lifestyle of our kids (LOOK) project : outline of methods

This methods paper outlines the overall design of a community-based multidisciplinary longitudinal study with the intent to stimulate interest and communication from scientists and practitioners studying the role of physical activity in preventive medicine. In adults, lack of regular exercise is a major risk factor in the development of chronic degenerative diseases and is a major contributor to obesity, and now we have evidence that many of our children are not sufficiently active to prevent early symptoms of chronic disease. The lifestyle of our kids (LOOK) study investigates how early physical activity contributes to health and development, utilizing a longitudinal design and a cohort of eight hundred and thirty 7&ndash;8-year-old (grade 2) school children followed to age 11&ndash;12 years (grade 6), their average family income being very close to that of Australia. We will test two hypotheses, that (a) the quantity and quality of physical activity undertaken by primary school children will influence their psychological and physical health and development; (b) compared with existing practices in primary schools, a physical education program administered by visiting specialists will enhance health and development, and lead to a more positive perception of physical activity. To test the first hypothesis we will monitor all children longitudinally over the 4 years. To test the second we will involve an intervention group of 430 children who receive two 50 min physical education classes every week from visiting specialists and a control group of 400 who continue with their usual primary school physical education with their class-room teachers. At the end of grades 2, 4, and 6 we will measure several areas of health and development including blood risk factors for chronic disease, cardiovascular structure and function, physical fitness, psychological characteristics and perceptions of physical activity, bone structure and strength, motor control, body composition, nutritional intake, influence of teachers and family, and academic performance.<br /
