It is well recognised that the adoption and longer term adherence to physical activity by adults to reduce the risk of chronic disease is a challenge. Interventions, such as group and home based physical activity programs, have been widely reported upon. However few studies have directly compared these interventions over the longer term to determine their adherence and effectiveness. Participant preference for home based or group interventions is important. Some evidence suggests that home based physical activity programs are preferred by middle aged adults and provide better long term physical activity adherence. Physiotherapists may also be useful in increasing physical activity adherence, with limited research on their impact.
'Physical Activity at Home' is a 2 year pragmatic randomised control trial, with a non-randomised comparison to group exercise. Middle-aged adults not interested in, or unable to attend, a group exercise program will be targeted. Sedentary community dwelling 50-65 year olds with no serious medical conditions or functional impairments will be recruited via two mail outs using the Australian federal electoral roll. The first mail out will invite participants to a 6 month community group exercise program. The second mail out will be sent to those not interested in the group exercise program inviting them to take part in a home based intervention. Eligible home based participants will be randomised into a 6 month physiotherapy-led home based physical activity program or usual care. Outcome measures will be taken at baseline, 6, 12, 18 and 24 months. The primary outcome is physical activity adherence via exercise diaries. Secondary outcomes include the Active Australia Survey, accelerometry, aerobic capacity (step test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio and body mass index. Costs will be recorded prospectively and qualitative data will be collected.
The planned 18 month follow-up post intervention will provide an indication of the effectiveness of the group and home based interventions in terms of adherence to physical activity, health benefits and cost. If the physiotherapy-led home based physical activity program is successful it could provide an alternative option for physical activity program delivery across a number of settings.

人们普遍认识到，成年人通过参加体育活动来降低慢性病风险，这一行为的采纳和长期坚持是一个挑战。团体和家庭为基础的体育活动项目等干预措施已被广泛报道。然而，很少有研究直接比较这些干预措施在较长时间内的效果，以确定它们的坚持程度和有效性。参与者对家庭或团体干预的偏好很重要。一些证据表明，家庭为基础的体育活动项目更受中年人的青睐，并能提供更好的长期体育活动坚持度。物理治疗师在增加体育活动坚持度方面也可能很有用，但对他们的影响的研究有限。
“在家锻炼”是一项为期 2 年的实用随机对照试验，与团体运动的非随机对照比较。目标人群为对团体运动项目不感兴趣或无法参加的中年成年人。将通过两次使用澳大利亚联邦选举名单的邮件招募不参加或不能参加团体运动项目的久坐社区居民 50-65 岁的人群。第一次邮件邀请参与者参加为期 6 个月的社区团体运动项目。第二次邮件将发给那些对团体运动项目不感兴趣的人，邀请他们参加家庭为基础的干预。符合条件的家庭基础参与者将被随机分配到为期 6 个月的物理治疗师主导的家庭体育活动项目或常规护理中。在基线、6、12、18 和 24 个月时将进行结果测量。主要结果是通过运动日记记录的体育活动坚持度。次要结果包括澳大利亚活跃调查、加速度计、有氧能力（台阶测试）、生活质量（SF-12v2）、血压、腰围、腰臀比和体重指数。将前瞻性记录成本，并收集定性数据。
计划的 18 个月干预后随访将提供关于团体和家庭为基础的干预在体育活动坚持度、健康益处和成本方面的有效性的指示。如果以物理治疗师为主导的家庭体育活动项目成功，它可以为在多个环境中提供体育活动项目提供替代方案。
