这项研究旨在确定步行运动变化的相关性。一个随机抽样邮寄运动调查的受访者被要求完成一个后续问卷24个月后，第一次。从1,739名成年人中获得了回复，回复率为86.6%。非受访者与受访者的基线水平步行锻炼没有差异。受访者过多地代表了白人和中等至高等教育（或收入）的成年人。运动行走变化的残差测量值作为因变量，根据基线行走进行调整。同样，在剩余化后纳入了随时间变化的关键自变量。在基线和24个月的随访中，成年人平均每周步行锻炼不到1小时，23.5%的最初活跃的成年人在2年后停止步行锻炼。多元回归分析解释了更多的差异，在步行锻炼女性比男性。动态变量的变化，如朋友的支持和剧烈的体力活动占了大部分的解释方差。结果表明，动态变量可能需要持续保持步行锻炼。有限的解释方差表明，需要确定更精确的措施和步行锻炼的其他决定因素。
This study was designed to identify correlates of change in walking for exercise. Respondents to a random sample mailed exercise survey were asked to complete a follow-up questionnaire 24 months after the first. Responses were obtained from 1,739 adults, reflecting an 86.6% return rate. Nonrespondents did not differ from respondents for baseline level of walking for exercise. Respondents overrepresented Caucasian and middle to high education (or income) adults. Residualized measures of change in walking for exercise served as the dependent variable, adjusted for baseline walking. Similarly, key independent variables, subject to change over time, were included after residualization. At both baseline and 24 months follow-up, adults walked for exercise an average of just under 1 hour per week, and 23.5% of the initially active adults ceased walking for exercise at 2 years. Multiple regression analyses explained more variance in walking for exercise among women than men. Change in dynamic variables such as friend's support and vigorous physical activity accounted for most of the explained variance. Results suggest that dynamic variables may need to be sustained to maintain walking for exercise. The limited explained variance suggests that more precise measures and additional determinants of walking for exercise need to be identified.
