The Effects of 8-week Resistance and Aerobic Exercise on Anxiety, Depression, Sleep, Inhibitory Control in Young Adults With Smartphone Overdependence

In this study, we will assess participants' sleep duration using a wrist-worn GENEActiv triaxial accelerometer (Activinsights, Cambridge, UK). Participants will be instructed to wear the device on their non-dominant wrist 24 hours a day for 8 days, except during contact sports that may pose a risk of injury. Sleep duration (minutes) is defined as the total time spent sleeping.

In this study, we will assess participants' sleep efficiency using a wrist-worn GENEActiv triaxial accelerometer (Activinsights, Cambridge, UK). Participants will be instructed to wear the device on their non-dominant wrist 24 hours a day for 8 days, except during contact sports that may pose a risk of injury. Sleep efficiency(%) is defined as the proportion of time spent asleep relative to time in bed

In this study, we will assess participants' time in bed using a wrist-worn GENEActiv triaxial accelerometer (Activinsights, Cambridge, UK). Participants will be instructed to wear the device on their non-dominant wrist 24 hours a day for 8 days, except during contact sports that may pose a risk of injury. Time in bed (minutes) is defined as the total time spent in bed, including both sleep and wakefulness

In this study, we will assess participants' sleep onset time using a wrist-worn GENEActiv triaxial accelerometer (Activinsights, Cambridge, UK). Participants will be instructed to wear the device on their non-dominant wrist 24 hours a day for 8 days, except during contact sports that may pose a risk of injury. Sleep onset time (hours and minutes) is defined as the time at which sleep begins.

In this study, we will assess participants' sleep onset time using a wrist-worn GENEActiv triaxial accelerometer (Activinsights, Cambridge, UK). Participants will be instructed to wear the device on their non-dominant wrist 24 hours a day for 8 days, except during contact sports that may pose a risk of injury. Wake time (hours and minutes) is defined as the final wake-up time.

Participants will visit the laboratory to complete the Beck Depression Inventory(BDI), a self-reported questionnaire assessing depressive symptoms. The BDI consists of 21 items, each scored on a scale from 0 to 3, with total scores ranging from 0 to 63. Higher scores indicate more severe depressive symptoms

Participants will visit the laboratory to complete the Beck Anxiety Inventory (BAI), a self-reported questionnaire assessing anxiety symptoms. The BAI consists of 21 items, each scored on a scale from 0 to 3, with total scores ranging from 0 to 63. Higher scores indicate more severe anxiety symptoms.

The Go/NoGo task will be used to measure the inhibition The measured variables will include reaction time (RT) and accuracy.

At the beginning of the test, a series of stimulus characters will be presented in the center of the screen one by one. Each stimulus character will be displayed for 400 ms, with a random interval of 400-700 ms between stimuli.

Before the test, participants will be informed that "L" is a Go stimulus and "C" is a NoGo stimulus. When "L" appears in the center of the screen, participants will be required to press the space bar key with their index finger as quickly and accurately as possible. When "C" appears, participants must not respond.

The system will record the reaction time and accuracy for Go stimuli and the accuracy for NoGo stimuli. The total number of stimulus characters will be 240, consisting of 180 Go stimuli (75%) and 60 NoGo stimuli (25%).
