The aim of this study is to investigate the effects of chronotype differences on balance and muscle strength in young adults. 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.
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.

All assessment measurements determined for individuals with morning chronotype will be performed first at 09:00 in the morning and then again at 19:00 in the evening. Muscle strength balance assessments performed in the morning and evening will be compared.
All assessment measurements determined for individuals with evening chronotype will be performed first at 09:00 in the morning and then again at 19:00 in the evening. Muscle strength balance assessments performed in the morning and evening will be compared.

Morningness-Eveningness Questionnaire
A questionnaire form that determines morningness and eveningness types will be used to subjectively evaluate circadian rhythm. defi - nitely morning type (70-86), moderately morning type (59-69), neither type (42-58), moderately evening type (31-41), and defi nitely evening type (16-30).
Time frame: 20 minutes
Single-leg standing test
This test measures a person's standing ability and balance.
Time frame: 20 minutes
Muscle strength test
Myometry will be used to objectively measure the strength of the quadriceps and hamstring muscles. Myometry is an evaluation method that objectively evaluates muscle strength and provides more sensitive results than manual muscle testing.
Time frame: 20 minutes
Timed up and go testTest:
A simple screening test that provides a sensitive and specific measure of fall risk and balance in older adults.
Time frame: 20 minutes
30 Second Sit-to-Stand Test
A test that evaluates the participant's sit-to-stand activity, lower extremity muscle strength and balance status.
Time frame: 20 minutes
