Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the present study is to evaluate the effect of partial and complete sleep deprivation on exercise heat tolerance. Twelve healthy young male volunteers will participate in the study. They will arrive to our lab four times, in each visit the will undergo VO2 test and Heat Tolerance Test (HTT) after sleeping different amount of hours.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The volunteers will arrive to our lab fout times- During their first visit they will go through a VO2 max test in order to evaluate their aerobic fitness, and their physiological efficiency will be measured. During their second visit they will go through an exercise heat tolerance test according to our validated protocol after a full night sleep. During the third and fourth visit they will go through an exercise heat tolerance test and a measurement of their physiological efficiency after a partial and complete sleep deprivation, respectively. The physiological tests will take place in the heat chamber that is located at the Heller Institute of Medical Research. The results will be then analyzed, and a comparison between the physiological measurements during the heat tolerance tests and the physiological efficiency tests after the various sleep conditions will be performed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

sleep deprivation

The research contains only one arm. The subjects will be tested with no sleep deprivation (which will be used as a control measurement) and with partial and complete sleep deprivation.

Group Type EXPERIMENTAL

partial and complete sleep deprivation

Intervention Type OTHER

The subjects will visit our labs 4 times. The second visit will be used as the experimental control. During the third and fourth visits the subject will go through an exercise heat tolerance test and a measurement of their physiological efficiency after a partial and complete sleep deprivation, respectively.
