Study aim
-
The effect of high-intensity interval training and sleep regulation and the combination of the two on some immune system indices (IgA, L-6 and IL-1β, hs-CRP, cortisol), physiological factors (body composition, anaerobic capacity, Neuromuscular coordination) and sleep quality of adolescent girls with sleep disorders.
-
Design
-
A randomized, one-blinded, controlled, semi-experimental with a parallel-group design of 80 adolescent females with sleep disorders. A lottery will be used for randomization.
-
Settings and conduct
-
This research is an applied quasi-experimental study and includes pre-test and post-test with 4 experimental groups in which the effect of independent variables of high-intensity interval training and sleep regulation and a combination of the two on some immune system indicators, physiological factors and sleep quality in girls 13 to 17 years with sleep disorders will be assessed. The site of the intervention and sports evaluations will be in the club and blood tests will be performed in a specialized laboratory. Collaborative researchers will be blind to pre-test and post-test evaluations and the statistical expert will be blind to how individuals are assigned to the groups.

-
Intervention groups
-
Eighty female students with sleep disorders based on the Pittsburgh Sleep Disorders Questionnaire (score 11 and above), will be identified and selected by convenience sampling method and randomly divided into 4 groups of 20 participants including high-intensity interval training, Sleep Regulation, Combined and Control groups.
-
Main outcome variables
-
Some immune system indicators (IgA, IL-6 and IL-1β, hs-CRP, cortisol)
