Impact of a Mobile Exercise Application on Sleep, Pain, and Fitness in Healthy Adults

The aim of this study is to evaluate the effectiveness of a commercially available mobile exercise application on performance-related physical fitness outcomes and selected health indicators in healthy young adults. A total of 78 participants are randomly assigned to a conventional exercise group (n = 26), a mobile application-based exercise group (n = 26), or a control group (n = 26). Both intervention groups complete an identical six-week high-intensity interval training (HIIT) program, either supervised or delivered via the 7-Minute Workout® mobile application. The control group receives no intervention. Pre- and post-intervention assessments include muscular endurance (curl-ups, push-ups), lower extremity anaerobic power (vertical jump), and hamstring and lower back flexibility (sit-and-reach), as well as self-reported sleep quality (Pittsburgh Sleep Quality Index) and pain (Visual Analog Scale).
