简介：CrossFit是有氧和无氧运动制度的组合，其既定目标是改善健身和身体表现。它越来越受欢迎，并有一个强大的社区，以激励和推动参与者最大限度地发挥作用。这些极端锻炼模式的负面影响很少被描述。CrossFit中受伤的患病率很高，但尚未评估运动成瘾和有害的运动态度。本研究的目的是测量运动成瘾的患病率在CrossFit和评估的可靠性和有效性的运动成瘾量表（EAI）在CrossFit population.METHODS：我们邀请crossfitters参加使用Facebook组的在线调查。共有603名常规交叉健身者完成了EAI和关于运动量和消极运动态度和信念的其他问题。我们使用主成分分析和结构方程模型来测试的EAI的心理测量特性，并描述了上瘾的crossfitters.RESULTS的特点：我们发现，5%的crossfitters沉迷于运动，年轻男性有较高的风险。EAI具有良好的内部信度（0.73）和结构效度。因此，我们发现显着的正相关运动成瘾和运动的倾向，尽管受伤，内疚的感觉时，无法行使，激情变成强迫症和服用药物，能够exercise.CONCLUSIONS：运动成瘾是普遍的CrossFit，需要进一步探索。建议在CrossFit社区和应用环境中进行EAI研究。
INTRODUCTION: CrossFit is a mix of aerobic and anaerobic exercise regimes with the stated goal of improving fitness and physical performance. It is growing in popularity and has a strong community known to motivate and push the participants to maximal performance. The negative consequences of these extreme exercise patterns have rarely been described. The prevalence of injuries in CrossFit is high but exercise addiction and harmful exercise attitudes have not yet been assessed. The aim of this study was to measure the prevalence of exercise addiction in CrossFit and to evaluate the reliability and validity of the Exercise Addiction Inventory (EAI) in a CrossFit population.METHODS: We invited crossfitters to participate in an online survey using Facebook groups. A total of 603 regular crossfitters completed the EAI and additional questions concerning exercise amounts and negative exercise attitudes and beliefs. We used principal component analyses and structural equation models to test the psychometric properties of the EAI and to describe the characteristics of the addicted crossfitters.RESULTS: We found that 5% of the crossfitters were addicted to exercise and that young males had a higher risk. The EAI had good internal reliability (0.73) and construct validity. Thus we found significant positive associations between exercise addiction and the tendency to exercise in spite of injury, feelings of guilt when unable to exercise, passion turning into obsession and taking medication to be able to exercise.CONCLUSIONS: Exercise addiction is prevalent in CrossFit and needs further exploration. The EAI is recommended for research in CrossFit communities and applied settings.
