近年來因政府積極推廣全民運動，許多公私立健身運動中心成立，進而提升 專業管理人員、服務人員與體適能指導員 (fitness instructor) 的大量需求，而體適 能指導員教學風格是吸引學員參與課程的主要因素之一。本文旨在討論體適能指 導員教學風格及學員參與動機之關係，首先提出體適能指導員與團體運動課程之 重要性，定義體適能指導員教學風格與參與動機，進一步透過文獻分析了解體適 能指導員教學風格與學員參與動機之關係。從眾多文獻結果得知，體適能指導員 在教導學員，應盡量提供具選擇性動作的領導，培養學員的自主性、讓其感受到 關心及熱忱，以增進其內在動機。當學員的內在動機愈強，其滿足感及持續參與 運動的意圖也會增強。最後本文針對體適能指導員提出建議，期望藉此可更深入 了解學員參與動機，加強其忠誠度。

In the recent years, due to the governments‘ active promotion of fitness, many public and private fitness centers and gyms have been established, leading to a large demand for professional managers, service staffs, and fitness instructors. And fitness instructors‘ teaching styles is one of the main factors which influence members‘ participation in classes. This study aimed to explore the relationship between fitness instructors‘ teaching styles and members‘ motivations to participate. First, the importance of fitness instructors and group exercise classes was discussed, and instructors‘ teaching styles and members‘ motivations to participate were defined. Then, through literature analysis, the relationship between fitness instructors‘ teaching styles and members‘ motivations to participate was further explored. According to several previous studies, when teaching members, fitness instructors shall try to provide guidance with optional movements, help members to be more independent, and make them feel instructors‘ concerns and enthusiasms, in order to increase their internal motivations. Stronger internal motivations lead to higher satisfaction and stronger intention to continuously participate in exercise classes. Lastly, this study provided some suggestions to fitness instructors and managers of fitness centers / gyms, in hopes of further understanding members‘ motivations to participate, for the purpose of improving their loyalty.
