EXERCISE ADHERENCE IN A BEHAVIORAL WEIGHT LOSS PROGRAM

描述：这项研究的目标是开发干预措施 改善肥胖成年人长期运动依从性的策略 以提高长期减肥效果。即使锻炼会有改善 长期的减肥维持，并降低 心血管疾病和II型糖尿病，肥胖的成年人 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，而且是短期的 通过以下途径使锻炼更方便，可以改善减肥效果 在多个短回合中进行处方锻炼，而不是每轮一轮 天。对长期坚持锻炼和减肥的影响没有 然而，已经进行了检查。他的发现还表明，提供更多 通过在家里放置锻炼器材的锻炼选项也可以 提高依从性，这一点从以下方面得到了证明： 家庭锻炼器材和体力活动的存在。然而， 目前还没有实验研究测试是否将运动器材 在家中实际上提高了锻炼的坚持性和减肥效果。这个 研究人员假设，在多个短时间内开出锻炼处方 比赛将提高长期锻炼的坚持性和长期体重 损失，而增加家庭锻炼器材将进一步 改善这些结果。 这项研究计划招募150名超重女性并将她们随机分组 三种疗法中的一种：1)长时间运动；2)短时间运动 锻炼；3)短跑锻炼+家庭锻炼器材。全 受试者将参加为期18个月的行为减肥计划， 其中体重在0、6、12和18个月时进行评估，并进行锻炼 在整个18个月中对遵守情况进行评估。心肺 健身和心血管疾病风险因素将在0， 6个月和18个月。

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.
