Title: 从偶尔到稳定：一项全面健身研究中的习惯形成见解

Abstract: Regular exercise is widely recognized as a cornerstone of health, yet sustaining consistent exercise habits remains challenging. Understanding the factors that influence the formation of these habits is crucial for developing effective interventions. This study utilizes data from Mars Athletic Club, T\"urkiye's largest sports chain, to investigate the dynamics of gym attendance and habit formation. The general problem addressed by this study is identifying the critical periods and factors that contribute to the successful establishment of consistent exercise routines among gym-goers. We show that specific periods of attendance are most crucial for habit formation. By developing a survival metric based on gym attendance patterns, we pinpoint these key phases and segment members into distinct clusters based on their visit patterns. Our analysis reveals significant differences in how various subgroups respond to interventions, such as group classes, personal trainer sessions, and visiting different clubs. Using causal inference analysis, we demonstrate that personalized guidance and social dynamics are key drivers of sustained long-term engagement. By systematically examining these variables and considering the specific characteristics of different clusters, our research highlights the importance of a tailored, multi-dimensional approach to promoting exercise habits, which integrates social dynamics, personalized guidance, and strategic interventions to sustain long-term engagement.

Abstract: 规律锻炼被广泛认为是健康的核心，但保持持续的锻炼习惯仍然具有挑战性。 了解影响这些习惯形成因素对于制定有效的干预措施至关重要。 本研究利用了火星健身俱乐部（Mars Athletic Club）的数据，这是土耳其最大的体育连锁店，以研究健身房出勤率和习惯形成的动力学。 本研究解决的一般问题是识别对健身房会员成功建立规律锻炼习惯至关重要的时期和因素。 我们表明，特定的出勤时期对于习惯形成最为关键。 通过基于健身房出勤模式的生存指标，我们确定了这些关键阶段，并根据他们的访问模式将会员分成不同的聚类。 我们的分析显示，不同子群体对干预措施（如团体课程、私人教练课程以及访问不同俱乐部）的反应存在显著差异。 通过因果推理分析，我们证明个性化指导和社会互动是长期持续参与的关键驱动因素。 通过系统地检查这些变量并考虑不同聚类的具体特征，我们的研究强调了促进锻炼习惯的定制化、多维方法的重要性，这种方法结合了社会互动、个性化指导和战略干预，以维持长期的参与度。
