Abstract

The purpose of this study was to evaluate the functionality, accuracy, and usability of a novel smart exercise application (SEA). The functionality such as counting lunges, providing task-related auditory feedback, and testing short-term memory was examined while thirteen young adults (six men, age 25.4 ± 8.3 years) performed the lunge exercise with the SEA. The accuracy of logged motion data including angles and accelerations were also tested. Another twenty-five participants (11 men, age 23.2 ± 5.7 years) evaluated the usability of the SEA interest, motivation, convenience, and strength/cognitive benefit via a questionnaire. The SEA assessed the lunge motion correctly, provided auditory feedback, and tested users’ short-term memory as required. High correlations (r = 0.90 to 0.99) with low RMSE (4.85˚ for direction angle, 0.13 to 0.22 m/s2 for acceleration) were observed between the sensor output and the reference output. Bland-Altman plot also showed a low discrepancy between each of the two measures. Most participants positively answered all questions about interest (60%), motivation (40%), convenience (80%), strength benefits (92%), and cognitive benefits (88%) of the SEA. The SEA demonstrated accurate kinematic assessment of accelerations and directions, assessed the lunge motion correctly, and created the appropriate auditory feedback on the short-term memory task. The high rate of positive responses suggested the potential of the application in future use.

智能运动应用程序，通过类似游戏的弓步运动改善腿部功能和短期记忆

本研究的目的是评估一个新颖的智能锻炼应用程序（SEA）的功能、准确性和可用性。在13名年轻人（6名男性，年龄25.4±8.3岁）使用SEA进行弓步运动时，对弓步计数、提供与任务相关的听觉反馈和测试短期记忆等功能进行了检查。还测试了记录的运动数据（包括角度和加速度）的准确性。另外25名参与者（11名男性，年龄23.2±5.7岁）通过问卷调查评估了SEA兴趣、动机、便利性和力量/认知益处的可用性。SEA正确评估了弓步动作，提供了听觉反馈，并根据需要测试了用户的短期记忆。在传感器输出和参考输出之间观察到高相关性（r=0.90至0.99）和低RMSE（方向角为4.85˚，加速度为0.13至0.22m/s2）。布兰德-奥特曼图也显示出两种测量之间的低差异。大多数参与者积极回答了关于SEA的兴趣（60%）、动机（40%）、便利性（80%）、力量优势（92%）和认知优势（88%）的所有问题。SEA展示了加速度和方向的精确运动学评估，正确评估了弓步运动，并在短期记忆任务中产生了适当的听觉反馈。高阳性反应率表明了该药物在未来应用中的潜力。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
