The aim of this study is to investigate the effect of listening to music on sleep quality in basketball players aged 16-18. A pre-test, post-test experimental design with a control group, a quantitative research design, was used in the study. The study group consisted of 10 female and 10 male athletes between the ages of 16-18 who actively participated in sports in the Ankara Regional Basketball League in 2025. They volunteered to use the MI BAND 4 (MiB) smartwatch. They were informed about the study and signed a consent form. The groups underwent an 8-week treatment. All participants were instructed to sleep between 11:00 PM and 12:00 PM every day for 8 weeks. Participants in the first group, who used the MI BAND 4 (MiB) smartwatch, were asked to refrain from accessing any technological devices or applications before bed. Participants in the second group, using the MI BAND 4 (MiB) smartwatch, were asked to listen to classical music for 15 minutes before bedtime. Data were analyzed using SPSS 22.0, and due to a sample size of less than 30, the Mann-Whitney U test and the Wilcoxon Signed-Rank Test were used for non-parametric statistics. The intervention program applied in the study was generally effective on the sleep components of the experimental group. Post-intervention comparisons showed statistically significant and large effect size improvements in the experimental group compared to the control group in many important variables, such as total sleep time, deep sleep time, time to fall asleep, number of nighttime awakenings, and overall sleep score, supporting this conclusion. However, no significant differences were observed in some variables, such as light sleep duration and REM sleep duration. However, this suggests that the intervention program only affected certain sleep components and did not have a uniform effect on all sleep parameters.
