Fitness coaches seem to play an essential role in the field of exercise as they help prevent sedentary lifestyles and promote overall health, quality of life, and well-being. This study aimed to explore the effects of fitness coaches’ behavior perceptions, intrinsic motivation, and enjoyment of exercisers on their long-term fitness and health, as well as their commitment to exercise. A total of 202 individuals participated in the study that was developed over three data gathering occasions (baseline, three months and six months). To this end, three psychometric scales were used as part of a multi-section survey: FCBS-Fit (perception of the fitness coach’s behavior), IMIp (intrinsic motivation of exercisers), and PACES (enjoyment in exercise), along with the assessment of four health/fitness variables: anthropometry (i.e., waist-hip ratio), strength (i.e., handgrip strength), flexibility (i.e., sit-and-reach), and cardiorespiratory fitness (i.e., VO2máx.). Overall, the results suggested that the perception of the fitness coach’s behavior, the exerciser’s intrinsic motivation, and enjoyment were predictors of the health/fitness outcomes, and seemed to be related to the exercise commitment at the end of three and six months. The novelty of this study is the examination of psychological and physiological factors in an integrated and longitudinal manner within the scope of exercise in fitness and health clubs. Therefore, these findings shed light on fitness coaches as an important element in the propagation and maintenance of exercise habits, accomplishment of tangible outcomes by exercisers, health promotion and the fitness sector’s growth.

健身教练在运动领域发挥着不可或缺的重要作用，可帮助人们规避久坐不动的生活方式，助力提升全民整体健康水平、生活质量与幸福感。本研究旨在探讨健身教练行为感知、锻炼者的内在动机与运动乐趣，对其长期健身健康状况及运动承诺的影响。本研究共招募202名受试者，分三次开展数据采集（分别为基线期、3个月随访期与6个月随访期）。为此，本研究在多模块问卷中采用了3套心理测量量表：FCBS-Fit（健身教练行为感知量表）、IMIp（锻炼者内在动机量表）与PACES（运动乐趣量表），同时对4项健康/健身相关指标进行评估：人体测量学指标（即腰臀比）、肌力指标（即握力）、柔韧性指标（即坐位体前屈）以及心肺适能指标（即VO2máx.）。整体而言，研究结果表明，健身教练行为感知、锻炼者内在动机与运动乐趣均可作为健康/健身结局的预测因子，且与3个月及6个月随访时的运动承诺显著相关。本研究的创新之处在于，在健身俱乐部的运动场景中，以整合式纵向研究设计对心理与生理因素展开探究。因此，本研究结果揭示了健身教练在传播与维持运动习惯、助力锻炼者达成切实健身成果、推动健康促进及健身行业发展中发挥的重要作用。
