Cardiovascular Health, Sleep
Conditions
Brief summary
The goal of this interventional study is to differentiate the effects of an acute partial sleep deprivation intervention on markers of cardiovascular health, cardio-autonomic function, physical and cognitive performance, as well as overall wellbeing in active vs sedentary individuals. The main aims of the project are: * To differentiate the effects of partial sleep deprivation on central hemodynamics (i.e., central blood pressure and arterial stiffness) in active vs sedentary individuals. * To differentiate the effects of partial sleep deprivation on physical (i.e., handgrip strength and reactive strength index) and cognitive performance (i.e., reaction time and impulse control) in active vs sedentary individuals. * To differentiate the effects of partial sleep deprivation on overall wellbeing (i.e., cardio-autonomic function, inflammation levels, and psychological mood states) in active vs sedentary individuals. Participants will be divided into two groups based on aerobic activity level - active or sedentary - and assessed for markers of cardiovascular health, cardio-autonomic function, physical and cognitive performance, as well as overall wellbeing before and after three days of normal sleep and three days of partially deprived sleep (i.e., 30% reduction in total time in bed).
