过去的工作联系锻炼身份和锻炼动机一直是横截面。本研究首次对不同类型的锻炼认同与锻炼动机之间的关系进行纵向建模。了解这些变量之间的动态关联对理论发展和应用研究具有重要意义。这是一项纵向调查研究。参与者是来自希腊的180名锻炼者（79名男性，101名女性），他们从健身中心招募，并被要求在6个月内完成三次问卷调查，评估锻炼身份（锻炼信念和角色认同）和锻炼动机（内在，识别，内向，外部动机和动机）。多水平增长曲线模型研究了动机调节作为运动身份的水平内和水平间预测因子的作用，以及运动身份预测人内和人间水平的运动动机的模型。结果表明，内在动机的人内变化，内向的，并确定的规定是积极的和负相关的人内变化的运动信念;内在动机也是一个积极的预测因素的人内变化的角色认同，但反之亦然。预测变量平均值的人与人之间差异可预测结果变量的初始水平和平均变化率。研究结果表明，一个强大的运动身份（特别是运动信念）可以促进加强这种身份的行为动机的主张。我们还证明，这种关系可以是互惠的超时，可以取决于类型的动机问题，以及人与人之间的差异，在这些变量的绝对水平。
Past work linking exercise identity and exercise motivation has been cross‐sectional. This is the first study to model the relations between different types of exercise identity and exercise motivation longitudinally. Understanding the dynamic associations between these sets of variables has implications for theory development and applied research. This was a longitudinal survey study. Participants were 180 exercisers (79 men, 101 women) from Greece, who were recruited from fitness centers and were asked to complete questionnaires assessing exercise identity (exercise beliefs and role‐identity) and exercise motivation (intrinsic, identified, introjected, external motivation, and amotivation) three times within a 6 month period. Multilevel growth curve modeling examined the role of motivational regulations as within‐ and between‐level predictors of exercise identity, and a model in which exercise identity predicted exercise motivation at the within‐ and between‐person levels. Results showed that within‐person changes in intrinsic motivation, introjected, and identified regulations were positively and reciprocally related to within‐person changes in exercise beliefs; intrinsic motivation was also a positive predictor of within‐person changes in role‐identity but not vice versa. Between‐person differences in the means of predictor variables were predictive of initial levels and average rates of change in the outcome variables. The findings show support to the proposition that a strong exercise identity (particularly exercise beliefs) can foster motivation for behaviors that reinforce this identity. We also demonstrate that such relations can be reciprocal overtime and can depend on the type of motivation in question as well as between‐person differences in absolute levels of these variables.
