The purpose of this paper is to examine the determinants of user adoption of smartphone fitness apps in context of an emerging economy.,The present study uses the extended unified theory of acceptance and use of technology (UTAUT2) as the base model along with two additional constructs, i.e. self-efficacy and personal innovativeness. The data collection was done through an online survey, wherein a total of 324 valid responses were obtained for the statistical analysis. All the hypothesized relationships were tested through partial least square structural equation modelling (PLS-SEM) using an open source programming language and software environment, i.e. R Software along with plspm-package.,Significant predictors of smartphone fitness app adoption intention include effort expectancy, social influence, perceived value, habit and personal innovativeness. Further, this study confirms significant relationship between personal innovativeness and habit, self-efficacy and effort expectancy and effort expectancy and performance expectation. This study reveals that personal innovativeness is the strongest predictor of behavioural intention. Contrary to the expectations, factors like performance expectancy, facilitating conditions and hedonic motivation did not influence behavioural intention.,This study gives significant clues to app developers that can drastically influence the adoption of fitness apps. The findings suggest that marketers should focus on users with high personal innovativeness that can further act as role models and significantly influence their social circle. Interestingly, the findings suggest that fitness apps, as compared to other apps, should not emphasize much on the hedonic value of their offerings.,This study is one of the few studies to examine the adoption of smartphone fitness apps in an emerging economy context by using extended version of UTAUT2 model. Further, this study shows how new endogenous and exogenous variables (i.e. self-efficacy and personal innovativeness) contribute to better explanatory power of the UTAUT2 framework.

消费者采用智能手机健身应用程序：UTAUT2的扩展视角

本文的目的是研究在新兴经济背景下用户采用智能手机健身应用程序的决定因素。本研究使用扩展的接受和技术使用统一理论（UTAUT2）作为基本模型，另外还有两个建构，即自我效能感和个人创新能力。数据收集是通过在线调查完成的，其中总共获得了324个有效响应用于统计分析。所有假设的关系均使用部分最小二乘结构方程模型（PLS-SEM），使用开源编程语言和软件环境（即R Software和plspm-package）进行了测试。智能手机适用性应用采用意向的重要预测因素包括预期工作量，社会影响力，感知价值，习惯和个人创新。此外，这项研究证实了个人创新能力和习惯，自我效能感和预期工作量以及预期工作量和绩效预期之间的重要关系。这项研究表明，个人创新是行为意图的最强预测因子。与期望相反，性能预期，便利条件和享乐动机等因素并未影响行为意图。本研究为可显着影响健身应用程序采用率的应用程序开发人员提供了重要线索。调查结果表明，营销人员应关注具有高度个人创新能力的用户，这些用户可以进一步充当榜样并显着影响其社交圈。有趣的是，研究结果表明，健身应用与其他应用相比，这项研究是通过使用UTAUT2模型的扩展版本来研究新兴经济环境中智能手机健身应用程序的采用的少数研究之一。此外，这项研究表明新的内源性和外源性变量（即自我效能和个人创新能力）如何有助于UTAUT2框架更好地解释。
