Effects of Exercise and Routine Change on Chronotype

You are being invited to take part in a research study. Whether you take part is up to you.

The purpose of this study is to examine the relationship between training activities and circadian rhythm chronotype (i.e., morning, neither, and evening type individuals). It is also to determine if chronotypes have shifted due to recent changes in schedules related to COVID-19. There are no direct benefits from participation in this study.

You will be asked to complete an online questionnaire. This questionnaire will consist of demographics (schedule, activities, age, gender, race, etc.), the Morningness-Eveningness questionnaire (time of day preference for various activities), and the Leisure Time Physical Activity Questionnaire (days/week you participate in physical activity). You will be asked to answer most of these questions under two conditions: before and after any schedule changes related to COVID-19. This questionnaire will take approximately 30 minutes to complete. You may save your answers and continue later if necessary. This questionnaire will be available via Qualtrics. You will be provided with a link or a QR code to access this questionnaire.

Your participation in this study is voluntary. You are free to withdraw your consent and discontinue participation in this study at any time without prejudice or penalty. Your decision to participate or not participate in this study will in no way affect your relationship with UCF, including continued enrollment, grades, employment or your relationship with the individuals who may have an interest in this study.

Only research investigators will have access to any data collected. You will not be asked to provide any personally identifying data. All data will be kept for 5 years and stored on password-protected computers in locked laboratories.

Inclusion Qualifications:

  • Males and females age 18-55 years old
  • Recreationally active individuals or athletes (training or practicing 3 times per week for 6+ months) prior to any schedule changes related to COVID-19.

Exclusion Qualifications:

You may not participate in this research opportunity if any of the following applies to you:
  • Sedentary individuals
