Detailed description

The aim of this study is to investigate the effects of chronotype differences on balance and muscle strength in young adults. Inclusion criteria are being between 45-65 years old, not having any neurological or orthopedic disorders, not having a vestibular disease that causes balance problems. Exclusion criteria are trauma history, anatomical deformities and skeletal system fractures, having a previous injury, and the presence of pain that will prevent participation in the tests. Chronotypes of all participants will be determined using the Morningness-Eveningness Questionnaire. All assessment measurements determined for young adult individuals will be performed first at 09:00 in the morning and then again at 19:00 in the evening. Muscle strength and balance assessments made in the morning and evening will be compared. Chronotypes of the participants will be evaluated with the Morningness-Eveningness Questionnaire, their balance will be evaluated with the One-Legged Standing Test, lower extremity muscle strength with a myometer, and their functionality will be evaluated with the Timed Stand-Up-Sit Test and the 30-Second Sit-Up Test.
