Despite the fact that group fitness instructors serve as significant role models with potentially great impact on class participants' motivation for exercise, they are a very under-researched group. The aim of this study was therefore to examine group fitness instructors' motivational regulations for exercise, and how these motivational regulations can predict symptoms of exercise dependence and body image concerns.
Group fitness instructors from the largest fitness companies in Norway ( = 837, response rate: 57%) completed an online survey with reference to the Situational Motivation Scale (SIMS), the Exercise Dependence Scale (EDS), the Eating Disorders Inventory subscales drive for thinness (EDI-DT) and body dissatisfaction (EDI-BD), and their weekly amount of exercise and instruction.
The instructors scored high on identified regulation and intrinsic regulation for exercise. EDS total score was positively correlated with all SIMS subscales and weekly instruction was positively correlated with Intrinsic regulation. Multiple hierarchical regression analyses found that both self-determined motivational regulations as well as external regulation positively predicted their EDS score. External regulation positively predicted EDI-DT, and EDI-BD.
Group fitness instructors seem highly intrinsically motivated for exercise, which is hypothesized to have a positive impact on group fitness class participants. High self-determined exercise behavior does not seem to buffer against symptoms of exercise dependence within this specific population. There is a need for awareness of group fitness instructors who show high exercise dependency scores due to the link to body image concerns, amotivation and external regulated motivation.
尽管团体健身教练是重要的榜样，对课程参与者的运动动机可能有很大影响，但他们是一个研究非常不足的群体。因此，本研究的目的是考察团体健身教练的运动动机调节方式，以及这些动机调节如何预测运动依赖症状和身体形象问题。
来自挪威最大健身公司的团体健身教练（n = 837，回复率：57%）完成了一项在线调查，调查涉及情境动机量表（SIMS）、运动依赖量表（EDS）、饮食失调量表的瘦身驱力分量表（EDI-DT）和身体不满分量表（EDI-BD），以及他们每周的运动量和授课量。
教练们在运动的认同调节和内在调节方面得分较高。EDS总分与所有SIMS分量表呈正相关，每周授课量与内在调节呈正相关。多重分层回归分析发现，自主动机调节和外部调节都能正向预测他们的EDS得分。外部调节正向预测EDI-DT和EDI-BD。
团体健身教练似乎对运动具有高度的内在动机，这被认为对团体健身课程参与者有积极影响。在这个特定人群中，高度自主的运动行为似乎并不能缓冲运动依赖症状。由于与身体形象问题、无动机和外部调节动机的联系，有必要关注那些运动依赖得分高的团体健身教练。
