Trial Design

3Treatment groups
Experimental Treatment
Placebo Group
Group I: Bright Light AloneExperimental Treatment1 Intervention
Bright light administered with Re-Timer glasses for 1 hour on 3 consecutive days. Following the 8 hour delay of the light/dark and sleep/wake cycle in the laboratory, the light will be administered, on average at 5:30-6:30 pm, 7:00-8:00 pm, and 9:30-10:30 pm, respectively on these three days.
Group II: Bright Light + Exercise + MelatoninExperimental Treatment1 Intervention
Bright light will be administered with Re-Timer glasses for 1 hour on 3 consecutive days. Following the 8 hour delay of the light/dark and sleep/wake cycle in the laboratory, the light will be administered, on average at 5:30-6:30 pm, 7:00-8:00 pm, and 9:30-10:30 pm, respectively on these three days. Exercise (1 hour at 65-75% heart rate reserve) will be administered on 3 consecutive, at 1:30-2:30 pm, 4:00-5:00 pm, and 6:30-7:30 pm on these days. Melatonin (0.5 mg) will be administered at 6 am, 8:30 am, and 11:00, on the 3 days.
Group III: Placebo ControlPlacebo Group1 Intervention
Dim red light will be administered with Re-Timer glasses for 1 hour on 3 consecutive days. Following the 8 hour delay of the light/dark and sleep/wake cycle in the laboratory, the light will be administered, on average at 5:30-6:30 pm, 7:00-8:00 pm, and 9:30-10:30 pm, respectively on these three days. Placebo tablets (0.5 mg) will be administered at 6 am, 8:30 am, and 11:00, on the 3 days.

Are there any prospective participants being registered for this experiment?

"Affirmative. As evidenced on clinicaltrials.gov, this research study is currently seeking candidates to participate in their trial which was first made available for enrollment on July 10th 2021 and last updated on May 16th 2022. A total of 36 patients are necessary at a single site."

Answered by AI

Who is qualified to become a participant in this trial?

"This clinical trial is looking to procure 36 patients who suffer from jet lag syndrome and are between 18-45 years old."

Answered by AI

What is the desired outcome of this clinical research endeavor?

"As the primary outcome, this medical trial will measure changes in sleep duration over a 6.5 day period. Secondary objectives include assessing z-machine recorded restorative slumber, analysing shifts in total mood disturbance on days 2-3 and 6-7 as per Profile of Mood States questionnaire data, plus ascertaining any alterations to peak Wingate Anaerobic Performance Test performance between days 2-3 and 6-7."

Answered by AI

How many participants has the clinical trial enrolled thus far?

"Affirmative, clinicaltrials.gov indicates that this medical trial is actively searching for participants as of the last update on May 16th 2022; with a total of 36 individuals to be recruited from one location. This study was originally posted online on July 10th 2021."

Answered by AI

Is enrollment limited to participants below thirty years of age?
