DESCRIPTION: The goal of this study is to develop intervention strategies that improve long-term exercise adherence in obese adults in order to improve long-term weight loss. Even though exercise improves long-term weight loss maintenance and reduces the risks of cardiovascular disease and Type II diabetes mellitus, obese adults are prone to drop out of exercise programs. The investigator's prior findings suggest that exercise adherence can be enhanced and short-term weight loss can be improved by making exercise more convenient via prescribing exercise in multiple short bouts, rather than one bout per day. Effects on long-term exercise adherence and weight loss have not been examined, however. His findings also suggest that providing more exercise options by placing exercise equipment in the home may also increase adherence, as evidenced by a significant correlation between the presence of home exercise equipment and physical activity. However, no experimental studies have tested whether placing exercise equipment in the home actually increases exercise adherence and weight loss. The investigator hypothesizes that prescribing exercise in multiple short bouts will improve long-term exercise adherence and long-term weight loss, and that the addition of home exercise equipment will further improve these outcomes. The research plan is to recruit 150 overweight women and randomize them to one of three treatments: 1) long-bout exercise; 2) short-bout exercise; 3) short- bout exercise + home exercise equipment. All subjects will participate in an 18-month behavioral weight loss program, in which body weight is assessed at 0, 6, 12, and 18 months and exercise adherence is assessed throughout the 18 months. Cardiorespiratory fitness and cardiovascular disease risk factors will be measured at 0, 6, and 18 months.

描述：本研究的目的是开发干预措施， 改善肥胖成年人长期运动坚持性的策略 以改善长期减肥。 尽管锻炼可以改善 长期减肥维持和降低风险， 心血管疾病和II型糖尿病，肥胖的成年人是 容易退出锻炼计划。 调查员的前科 研究结果表明，锻炼的坚持性可以提高， 减肥可以通过使运动更方便， 规定运动在多个短回合，而不是一个回合， 天 对长期坚持锻炼和减肥的影响还没有 然而，被检查。 他的研究结果还表明， 通过在家中放置锻炼设备的锻炼选项还可以 增加依从性，这一点可通过以下因素之间的显著相关性得到证明： 家庭锻炼设备和体育活动的存在。 然而，在这方面， 没有实验研究测试过放置运动器材是否 实际上增加了锻炼的坚持性和减肥效果。 的 研究人员假设，在多个短期处方运动 比赛将提高长期锻炼的坚持性和长期体重 损失，并增加家庭锻炼设备将进一步 改善这些成果。 研究计划是招募150名超重的妇女，并将她们随机分组 三种治疗方法之一：1）长时间锻炼; 2）短时间锻炼 3）短打运动+家庭健身器材。 所有 受试者将参加18个月的行为减肥计划， 其中在0、6、12和18个月时评估体重， 在整个18个月内评估依从性。 心肺 健康和心血管疾病风险因素将被测量为0， 6个月和18个月。
