The increasing number of older women in Australia presents a significant challenge to our health system. Preventative and health promotion strategies must be developed for this important group of Australian's if chronic disease and disability are to be contained and the decline in functional capacity attenuated. One potential intervention strategy is regular exercise. However, if exercise is to have multi-systems benefits, the dose of the exercise must be known. We do not know the exercise prescription that will maximize those health benefits required for this group of Australian's. We propose to resolve this situation via two related experiments involving women aged 65-74 yr. Experiment 1 will select moderate-intensity treadmill walking for 30 min-session with the weekly exercise frequency varied from 1 to 5 session-wk for 64 sessions. Experiment 2 will also select moderate-intensity treadmill walking with the total exercise time per week (120 min-wk) and the number of weeks of training (24 wk) fixed but varying the exercise duration per session (24 to 120 min-session) and the exercise frequency per week; 5 (x 24 min) to 1 (x 120 min) session-wk. Each subject will undergo lung function tests, body fat test, fitness tests and blood tests at selected time intervals throughout each experiment. A separate fitness test will be conducted on the subjects' leg muscle to help us understand what is happening directly in the muscle. We will also conduct a tilt test to help us understand how regular exercise might lessen the likelihood of 'falls' in older individuals. We expect to determine the optimum exercise prescription to improve health and minimize injury and misadventure. It is essential that GP's who have the main responsibility for prescribing exercise for their older patients, have access to knowledge on the optimum exercise prescription to maximize the beneficial changes in health and functional capacity in females aged 65-74 yr.

澳大利亚老年妇女人数的不断增加对我们的卫生系统提出了重大挑战。如果要遏制慢性病和残疾，减缓功能能力的下降，就必须为澳大利亚这一重要群体制定预防和促进健康的战略。一个潜在的干预策略是定期锻炼。然而，如果运动对多系统有益，那么必须知道运动的剂量。我们不知道运动处方，将最大限度地提高这些澳大利亚人所需的健康益处。我们建议通过两个涉及65-74岁妇女的相关实验来解决这种情况。实验一选择中等强度的踏车行走，每周运动1 ~ 5次，每次30 min，共64次。实验2还将选择中等强度的跑步机行走，每周总运动时间（120分钟-周）和训练周数（24周）固定，但改变每次运动持续时间（24至120分钟-周）和每周运动频率; 5（x 24分钟）至1（x 120分钟）会话-周。每名受试者将在每次实验期间的选定时间间隔接受肺功能测试、体脂测试、体能测试和血液测试。将对受试者的腿部肌肉进行单独的体能测试，以帮助我们了解肌肉中直接发生的情况。我们还将进行倾斜测试，以帮助我们了解定期锻炼如何减少老年人“福尔斯”的可能性。我们期望确定最佳的运动处方，以改善健康和减少伤害和事故。至关重要的是，全科医生的主要责任是为老年患者开运动处方，他们可以获得最佳运动处方的知识，以最大限度地提高65-74岁女性的健康和功能能力。
