我们在这里报告了来自Project Active的设计和基线数据，这是一项为期两年的随机试验，旨在比较生活方式体育活动干预和传统结构化运动处方方法的有效性。主要结果指标是体力活动中的能量消耗(以每千克体重的能量消耗估计)和心肺健康(以最大摄氧量衡量)。参与者是235名最初久坐不动、看起来很健康的成年人，他们被随机分为生活方式干预组或结构性干预组。生活方式治疗包括一种个性化的方法，考虑到个人的动机准备和将身体活动融入日常生活的偏好。结构化方法是常见的运动处方，它基于频率、强度和持续时间公式。需要检验的主要假设是，在24个月结束时，这两种情况下的体力活动和心肺健康指标将会有所不同。第二个假设是，在6个月结束时，两组在体力活动和心肺功能方面都将比基线有显著改善。在积极干预6个月之后，两组都进行了18个月的渐进式后续维持干预。在6个月和24个月后测量主要结果。
We report here the design and baseline data from Project Active, a 2-yr randomized trial designed to compare the effectiveness of a Lifestyle physical activity intervention with the traditional Structured exercise prescription approach. Primary outcome measures are energy expenditure in physical activity (estimated by kcal per kilogram of body weight of energy expenditure) and cardiorespiratory fitness (measured by maximal oxygen uptake). The participants, 235 initially sedentary and apparently healthy adults, were randomized into either the Lifestyle or Structured intervention groups. The Lifestyle treatment consists of a personalized approach that accounts for an individual's motivational readiness and preferences for integrating physical activity into daily routines. The Structured approach is the familiar exercise prescription that is based on a frequency, intensity, and duration formula. The primary hypothesis to be tested is that there will be a difference in physical activity and cardiorespiratory fitness measures between the two conditions at the end of 24 months. The secondary hypothesis is that both groups will make significant improvements from baseline in physical activity and cardiorespiratory fitness at the end of 6 months. Six months of active intervention are followed by 18 months of a tapered follow-up maintenance intervention in both groups. Primary outcome measures are measured after 6 and 24 months.
