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 at least 30 minutes of moderate intensity physical activity (eg. brisk walking at 4.8-6.4 km-hr) on most days is sufficient to confer these significant health benefits. Many older Australians spend substantial amounts of time engaged in household and garden chores 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 and garden activities 2. provide data that are required to estimate accurately the prevalence of 'adequate' levels of physical activity among older adults 3. identify indirect methods (such as heart rate, motion and breathing frequency) which, in combination, are suitable for estimating energy expenditure in large scale surveys. The outcomes of this study will be: 1. A greatly improved understanding of whether for older Australians (55-65 years) energy expenditure of self-paced household and garden 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 ~45% of insufficiently active older 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.

定期参加中等至剧烈强度的体育活动可降低患心血管疾病、非胰岛素依赖型糖尿病、骨质疏松症和某些癌症的风险。最近流行病学的建议是，至少30分钟的中等强度的体力活动（如。以4.8-6.4公里-小时的速度快步行走）足以带来这些显著的健康益处。许多澳大利亚老年人花费大量时间从事家务和园艺工作，但不知道这些活动的强度是否足以带来上述健康益处。因此，本研究的目的是：1。直接测量自定进度的普通家庭和花园活动的能源成本2.提供准确估计老年人身体活动“适当”水平的普遍性所需的数据。确定间接方法（如心率、运动和呼吸频率），这些方法结合起来适用于估计大规模调查中的能量消耗。本研究的结果将是：1。大大提高了对澳大利亚老年人（55-65岁）自主安排家务和园艺活动的能量消耗是否足以带来健康益处的认识。2.我们的研究结果将用于关键的公共卫生干预措施，旨在改变澳大利亚人的身体活动水平。3.如果公共卫生信息鼓励约45%的活动不足的澳大利亚老年人定期进行中等强度的体育活动，那么这将降低医疗保健系统的成本，大大减少过早死亡，并减少发病率和残疾。4.我们的研究结果将有助于公共卫生流行病学家监测澳大利亚人中身体活动充足的比例。
