The impact of fitness tracking applications on the physical health of young adults: a cross-sectional comparative study

Abstract The growing focus on health and wellness among young adults has resulted in a rise in the use of fitness tracking apps. Although numerous studies indicate that these tools have a positive impact on physical activity, there are ongoing questions regarding their long-term viability and risk of becoming overly dependent on them. This research aimed to assess whether fitness tracking app use is associated with better physical health and behavioural patterns among young adults. A cross-sectional comparative observational study design was used, with participants split into app users and non-users. The Short Form-12 (SF-12) was used to assess physical health quality of life, while physical activity levels were measured using the International Physical Activity Questionnaire (IPAQ). Statistical analyses were carried out using MedCalc and SPSS. App users showed significantly higher physical health scores (49.35 ± 1.43) compared to non-users (36.35 ± 1.43; ). Furthermore, 56% of app users were categorised as ‘high activity’ according to the IPAQ, in contrast to 40% of non-users. Fitness tracking applications were associated with higher physical activity levels and better health-related quality of life among young adults. Future study should investigate their long-term effects and replicate these findings in broader and more diverse groups.
