This study examined the effects of two maintenance programs on exercise participation, energy expenditure, energy consumption, and weight change in 67 obese adults undergoing behavioral weight-loss treatment. Following an initial 6-month treatment phase which produced a mean weight loss of 8.8 kg, participants were assigned randomly to an exercise-focused maintenance program or to a weight-focused maintenance program. Both maintenance programs included 6 months of biweekly group sessions. The exercise-focused program included supervised group walking sessions, individual and group contingencies for exercise completion, and relapse prevention training targeted specifically at the maintenance of physical activity. The weight-focused program contained a general focus on the maintenance of weight-loss through therapist-led group problem-solving of weight-related problems presented by individual participants. At the completion of the maintenance program and at long-term follow-up, there were no significant differences between conditions in exercise participation or energy expenditure. However, during the year following initial treatment, participants in the weight-focused program demonstrated significantly greater reductions in fat consumption and significantly better maintenance of weight losses than subjects in the exercise-focused program.
本研究调查了两种维持计划对67名接受行为减肥治疗的肥胖成年人运动参与度、能量消耗、能量摄入和体重变化的影响。在最初为期6个月的治疗阶段平均减重8.8千克后，参与者被随机分配到以运动为重点的维持计划或以体重为重点的维持计划。两个维持计划均包括为期6个月的每两周一次的小组会议。以运动为重点的计划包括有监督的小组步行活动、针对运动完成情况的个人和小组应急措施，以及专门针对维持身体活动的复发预防训练。以体重为重点的计划总体上侧重于通过治疗师主导的小组解决个体参与者提出的与体重相关问题来维持减肥效果。在维持计划结束时和长期随访中，各条件下的运动参与度或能量消耗没有显著差异。然而，在初始治疗后的一年中，与以运动为重点的计划中的受试者相比，以体重为重点的计划中的参与者脂肪摄入量显著降低，体重减轻维持得明显更好。
