Investigation of the Effects of Chronotype Differences on Balance and Muscle Strength in Young Adults

Condition(s) studied

Investigational drug(s) / intervention(s)

Morning chronotype: 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.

Evening chronotype: 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.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Morningness-Eveningness Questionnaire — 20 minutes
  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).
• Single-leg standing test — 20 minutes
  This test measures a person's standing ability and balance.
• Muscle strength test — 20 minutes
  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.
• Timed up and go testTest: — 20 minutes
  A simple screening test that provides a sensitive and specific measure of fall risk and balance in older adults.
• 30 Second Sit-to-Stand Test — 20 minutes
  A test that evaluates the participant's sit-to-stand activity, lower extremity muscle strength and balance status.
