. In our study, demographic information (age, gender, height, weight, education, marital status, occupation, where and with whom they live), additional diseases, medications used, whether they live in a rural or urban area, whether they have had any sleep problems before, and whether they have had any psychiatric diagnoses before will be recorded for all subjects. Before the exercise, students will fill out the Pittsburgh Sleep Quality Index to determine their sleep quality, the Morningness-Eveningness Scale to assess their chronotype, and the Beck Depression Inventory to measure their depressive symptom levels, and the results will be recorded. Students taking the body mechanics course will be asked to do aerobic exercises they learned in class, three days a week, including warm-up and cool-down, for a total of 60 minutes of exercise. The exercises will be performed on the same days and times each week. All exercises performed by the students for 8 weeks will be monitored by the rese

This index includes 19 items designed to evaluate sleep quality in the last month. Subjective sleep quality consists of sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, sleeping pill use and daytime sleep dysfunction. Each component is evaluated on a 0-3 scale. The total score has a value between 0-21. A high total score indicates poor sleep quality. A total PSQI score greater than 5 is an indicator of a significant level of sleep disturbance. The validity and reliability studies of this scale for our country were conducted by Ağargün et al. in 1996.

This scale helps determine when individuals are more active and awake in accordance with their biological clocks. The scale consists of a total of 19 items and includes questions aimed at determining whether individuals are morning type, evening type, or intermediate type. These questions cover topics such as individuals' sleep and wakefulness habits, performance levels in the morning and evening hours, and when they feel more energetic. The sum of the scores given to each item determines the person's morning or evening tendency: Morning individuals are more energetic in the early hours and work more efficiently in the morning. Evening individuals are more energetic in the late hours and work more efficiently in the evening. Intermediate individuals, on the other hand, can perform in a balanced manner at different times of the day without showing a clear morning or evening tendency. The total score helps classify the individual as being in accordance with their circadian rhythm. The v

This scale is widely used in the evaluation of depression, especially in psychiatric practices and clinical research. The BDI consists of a total of 21 items, and each item includes the basic symptoms of depression (e.g. sadness, hopelessness, sleep disorders, appetite changes, feelings of worthlessness). Each item is scored between 0 and 3. Scores increase according to the severity of the individual's symptoms, and the total score varies between 0 and 63. Individuals who score between 0 and 13 have no or mild depression. Scores between 14 and 28 indicate moderate depression. Scores between 29 and 63 indicate severe depression. A high total score indicates more severe depression. The BDI is frequently used to better understand individuals' depression levels and to monitor progress in the treatment process. The validity and reliability studies of this scale were conducted by Hisli in 1986.
