|---|---|---|---|
| resistance exercise group | Experimental | They will perform resistance exercise for 8 weeks. |

| Measure | Description | Time Frame |
|---|---|---|
| sleep duration | 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. | pre intervention: for 8days(before the intervention) / post intervention: for 8days(after the intervention) |
| Sleep efficiency | 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 | pre intervention: for 8days(before the intervention) / post intervention: for 8days(after the intervention) |
| 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 | pre intervention: for 8days(before the intervention) / post intervention: for 8days(after the intervention) |
| Sleep onset time | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Depression | 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 | pre intervention(day 1), post intervention(day 57) |

resistance exercise group → Experimental aerobic exercise group → Experimental control → No Intervention There are three groups in this study: the resistance exercise group, the aerobic exercise group, and the control group. Measurements are conducted at three time points: pre-intervention, mid-intervention (4 weeks after the intervention), and post-intervention

| wake time | 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. | pre intervention: for 8days(before the intervention) / post intervention: for 8days(after the intervention) |
| Anxiety | 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. | pre intervention(day 1), post intervention(day 57) |
| Inhibition | 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%). | pre intervention(day 1), post intervention(day 57) |
