Student Exercise and Sleep Timing Study - Part 2
(SiESTa 2)
What this study is about
The purpose of this study is to examine the effects of a morning exercise intervention on sleep (quality and duration), mood (positive affect, anxiety, depression, anger), stress and productivity among undergraduate students (18-23 years) evening-exercisers with poor self-reported sleep quality. Aim 1.
View original scientific description
The purpose of this study is to examine the effects of a morning exercise intervention on sleep (quality and duration), mood (positive affect, anxiety, depression, anger), stress and productivity among undergraduate students (18-23 years) evening-exercisers with poor self-reported sleep quality. Aim 1. Compared to the control condition, evening-exercisers prescribed morning exercise will exhibit improved sleep quality (increased efficiency, decreased fragmentation) and increased sleep duration. Aim 2. Compared to the control condition, evening-exercisers prescribed morning exercise will exhibit improved mood (increased positive affect, decreased depression, anxiety and anger). Aim 3. Compared to the control condition, evening-exercisers prescribed morning exercise will exhibit decreased stress and increased productivity.
Interventions
BEHAVIORAL
Morning Exercise
Exercise is changed from normal (6pm-11pm) exercise to morning (6am-11am) exercise.
Primary outcome measures
Sleep Quality
Time frame: 2 weeks
Determine if, compared to a control condition (maintaining usual schedule), shifting exercise from evening to morning improves sleep (quality and duration). Sleep quality includes variables such as the actigraph measured sleep period, total sleep time, sleep efficiency, and wake after sleep onset. Sleep quality and duration will be measured using wrist actigraphy, specifically the Phillips Actiwatch Spectrum Plus devices. The Epworth Sleepiness Scale will also be utilized to measure sleep quality, where scores range from 0-24 and higher scores signify more exhaustion and poorer sleep quality.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
