This descriptive quantitative study assessed the relaxation levels of high school student-athletes in Carmen, Davao del Norte, focusing on cognitive state anxiety, somatic state anxiety, and self-confidence. A total of 100 respondents were selected, and data were gathered using validated questionnaires. Statistical tools such as mean, standard deviation, t-test, and ANOVA were employed to analyze relaxation levels and their relationship to demographic variables. Results indicated a moderate overall relaxation level (M = 33.4, SD = 1.04). Cognitive state anxiety (M = 32.5) and self-confidence (M = 37.2) were both rated high, while somatic state anxiety (M = 30.5) was moderate. Significant differences were observed in relaxation levels when grouped according to age (p = 0.0002) and year level (p = 0.0001), but not by sex (p = 0.238). Findings support Herbert Bensons Relaxation Response Theory, highlighting the importance of structured interventions in enhancing relaxation and psychological well-being. The study recommends the integration of cognitive-behavioral techniques, mindfulness practices, and self-confidence development in school-based athletic programs.
