Relationship between sit-to-stand tests and lower extremity muscle strength in young adult individuals

Turan, H. (2024) The relationship between sit-to-stand tests and lower extremity muscle strength in young adults. Master's, Istanbul Atlas University Education Institute, Department of Physiotherapy and Rehabilitation, Istanbul. This study was conducted to determine the relationship between the Sit to Stand Test (STST) performances of young adults and their lower extremity isometric muscle strength and to detect the difference between genders. 33 female and 33 male young adult individuals with an average age of 20.80±1.42 years participated in the study. The demographic characteristics of all individuals were recorded. 5-repetition Sit to Stand Test, 10 second Sit to Stand Test, 30 second Sit to Stand Test, One-minute Sit to Stand Test performances were determined and lower extremity muscle strengths; Knee extension, knee flexion, hip extension, hip flexion, hip abduction isometric muscle strengths were evaluated with a Hend Held Dynamometer(HHD) for both legs. A significant difference was obtained in lower extremity isometric muscle strength between genders (p <0.005). A significant difference was found between genders in all Sit to Stand tests (p<0.005). A small correlation was detected between sit-to-stand tests and total lower extremity isometric muscle strength (p<0,05). Future studies are needed to examine the holistic relationship of sit to stand tests not only with muscle strength but also with other parameters such as sensorimotor, balance and psychological factors.
