To examine the interactive effects of exercise identity (EI) and outcome expectations (OE) on constraints, constraint self-regulation, and leisure-time physical activity (LTPA).
Surveyed a convenience sample of middle-aged and older adults (N = 271) at a metropolitan park agency in the Midwest.
The final reduced model predicted 24% of the variance in LTPA, including an indirect effect of EI x OE through intrapersonal constraints.
Results suggest that these social cognitive factors are useful in understanding low to high-intensity LTPA and have implications for LTPA programs for adults aged 50 and older.
探讨运动身份认同（EI）和结果期望（OE）对限制因素、限制自我调节和休闲时间身体活动（LTPA）的交互作用。
对美国中西部一个城市公园管理机构的中老年成年人便利样本（N = 271）进行了调查。
最终简化模型预测了LTPA中24%的方差，包括EI×OE通过个人内部限制因素产生的间接效应。
结果表明，这些社会认知因素有助于理解低强度到高强度的LTPA，并且对50岁及以上成年人的LTPA项目具有启示意义。
