Objective

Though exercise behaviors are typically viewed as health-promoting, certain forms of exercise (i.e., excessive exercise, unhealthy muscle-building behaviors) are considered maladaptive and are associated with negative physical and psychological outcomes. Psychosocial factors may put people at greater risk for engaging in maladaptive exercise. Based on deviance regulation theory, weight bias was examined as a potential moderator of the association between exercise identity and both excessive exercise and muscle-building behaviors.

Design

The current study is a secondary analysis of a larger data set investigating associations between athletic identity, exercise behaviors, and disordered eating behaviors. Hypotheses were examined using moderation testing in multiple linear regression.

Main outcome measures

Participants (N = 225, 50.2% female) completed the Eating Pathology Symptoms Inventory as a measure of maladaptive exercise.

Results

Controlling for sex, age, athlete status, and body mass index, weight bias moderated the association between exercise identity and both excessive exercise and muscle-building behaviors. Among individuals with high exercise identity, higher weight bias was associated with increased maladaptive exercise behaviors.

Conclusion

Individuals with higher exercise identity and higher weight bias may be at greatest risk of engaging in maladaptive exercise. Preventive interventions for maladaptive exercise behaviors may consider targeting exercise identity and weight bias.

研究体重偏差对运动身份与适应不良运动行为之间关联的影响

客观的

尽管运动行为通常被视为促进健康，但某些形式的运动（例如，过度运动，不健康的肌肉锻炼行为）被认为具有不良适应能力，并与负面的身心后果有关。社会心理因素可能使人们更有可能从事适应不良的运动。基于偏差调节理论，体重偏倚被视为运动身份与过度运动和肌肉锻炼行为之间潜在的调节因素。

设计

当前的研究是对较大数据集的二次分析，该数据集调查了运动身份，运动行为和饮食失调行为之间的关联。假设使用多元线性回归中的适度检验进行检验。

主要观察指标

参与者（N  = 225，女性50.2％）完成了《饮食病理症状清单》，作为对不良适应运动的一种量度。

结果

通过控制性别，年龄，运动员状态和体重指数，体重偏差可以缓解运动身份与过度运动和肌肉锻炼行为之间的关联。在具有较高运动身份的个体中，较高的体重偏倚与不良适应运动行为增加有关。

结论

具有较高运动身份和较高体重偏见的个体可能最容易遭受适应不良的运动。对不良适应性运动行为的预防性干预可考虑针对运动身份和体重偏差。
