Wpływ programu ćwiczeń z wykorzystaniem aplikacji na smartfonie, z nadzorem zdalnym lub osobistym, na wydolność funkcjonalną osób starszych: randomizowane badanie kliniczne

INTRODUCTION: Population aging is a significant global challenge, demanding strategies that promote healthy aging. Regular physical activity is crucial for maintaining functional capacity, quality of life, and preventing chronic diseases in older adults. However, sedentary behavior remains high, and evidence on effective, supervised smartphone-based exercise strategies for older adults is limited. OBJECTIVE: To evaluate the effects of smartphone-based exercises with in-person or remote therapeutic supervision on functional capacity. METHODS: Thirty-four older adults were randomized into two training groups with App-based exercises: a Control Group with in-person supervision and an Experimental Group with remote supervision. The exercises were performed three times a week for 8 weeks. The Experimental Group performed exercises at homes with remote supervision, and the Control Group performed exercises in the laboratory. Functional capacity was measured using the Glittre Activities of Daily Living (Glittre ADL) test, postural balance with the Mini Balance Evaluation Systems Test, and lower limb strength with the Five Times Sit-to-Stand test. RESULTS: Both groups demonstrated significant improvement in functional capacity. After 8 weeks, Glittre-ADL test time reduced similarly in both groups (Experimental Group: 217±63 to 188±47 s and Control Group 194±34 to 171±30 s, ES=0.09). Postural balance improved similarly in both groups (ES=0.15), and the lower limb strength improved in the Experimental Group (ES=0.32). CONCLUSION: A smartphone App-based exercise program, with and without in-person supervision, improved functional capacity and postural balance in older adults, whereas lower limb strength improved only with in-person supervision.
