Smartphone Use and Exercise Characteristics

Hedonic smartphone use, or playing with a mobile device, is linked to Problematic Smartphone Use (PSU). This study examined how exercise practices, such as frequency, duration, and perceived intensity, relate to hedonic and utilitarian (sports- and work-context) smartphone use. Regularly exercising adults (360, 132 men, M age = 39.0±9.8, M weekly exercise = 5.8±1.9) volunteered for the study and provided demographic information about their exercise and smartphone use habits. Results showed that exercise characteristics affected the total daily smartphone use, with perceived exercise intensity having a negative effect. Moreover, exercise frequency and duration (but not intensity) positively affected sports-related smartphone use, which was inversely related to hedonic use. Therefore, exercise practices affect daily smartphone use and indirectly affect hedonic use by promoting utilitarian use. The current results may account for the inverse relationship between regular exercise and PSU. Further research on testing the mechanism by which exercise lowers hedonic smartphone use is needed.享乐型智能手机使用（hedonic smartphone use），即日常把玩移动设备，与问题性智能手机使用（Problematic Smartphone Use, PSU）存在关联。本研究探讨了锻炼行为（包括锻炼频率、时长与感知运动强度）与享乐型智能手机使用及实用型（涵盖运动与工作场景）智能手机使用（utilitarian smartphone use）之间的关联。360名规律锻炼的成年人自愿参与本研究，其中男性132名，平均年龄为39.0±9.8岁，周均锻炼时长为5.8±1.9小时；参与者需报告自身锻炼与智能手机使用习惯相关的人口统计学特征及行为信息。研究结果表明，锻炼特征会影响每日总智能手机使用时长，其中感知运动强度存在负向影响。此外，锻炼频率与时长（而非强度）对运动相关智能手机使用存在正向影响，而该类使用与享乐型智能手机使用呈负相关关系。由此可见，锻炼行为会影响每日智能手机使用时长，并通过促进实用型智能手机使用，间接影响享乐型智能手机使用。本研究结果可解释规律锻炼与问题性智能手机使用之间的负相关关系。未来仍需开展进一步研究，以验证锻炼降低享乐型智能手机使用的内在作用机制。
