简要总结
Adolescence is characterized by major transitions in sleep and circadian rhythm. This rapid pivotal period increases the risks of sleep debt and poor sleep quality, leading to pronounced diurnal fatigue and drowsiness. On the other hand, academic stress has been also associated with increased sleep disturbances.
Both academic stress and poor sleep in adolescents has been linked to increased sleepiness rate, reduced alertness, lower academic performances and the impairment of the control of energy balance through hyperphagia.
Despite the importance of sleep in holistic development, physical (i.e. recovery, metabolism, muscle growth, weight control), cognitive (i.e. learning, memory, decision-making, Vigilance). Few studies have been designed to improve this behavior among college adolescents, especially in times of academic stress.
Physical activity has been suggested as a non-pharmacological alternative treatment for sleep disorders . Generally, it is well established that the duration and quality of sleep were improved by regular physical activity among adolescents and far better, it was suggested that the exercise-mediated effect on sleep could be even observed in the short term. Moreover, it was suggested that aerobic exercise has positive effects on psychological stress and well-being of adolescents .
Therefore, APADOSLEEP trial, was designed to examine the effect of physical activity program on sleep during and outside periods of academic stress.
详细描述
Counterbalanced, cross-over, pre-post trial where each subject acts as his own control.
Four sessions will be performed for each adolescent. Each session will be conducted over 5 days (from Monday to Friday):
Adolescents will take part randomly in four sessions. Physical activity program will be identical between sessions and groups. 60 minn of moderate to vigorous leisure activities and exercises will be proposed each day. Heart rate monitor will be used to control intensity of exercise during the physical activity program.
- Control session (CTL) outside academic stress period (represented by exams) and without the physical activity program.
- A session outside academic stress period, with the physical activity program (PAP).
- A session during an academic stress period without the physical activity program (AS).
- A session during an academic stress period with the physical activity program (ASPAP).
At each session:
