Abstract This study aimed to determine the influence of physical activities on self-concept, health lifestyle, and resilience of senior high school students in the Province of Negros Occidental during the school year 2025–2026. Specifically, it examined the extent of students’ physical activity, their levels of self-concept, health lifestyle, and resilience, as well as the significant differences and relationships among these variables. It also identified the predictors of resilience and proposed physical education activity exemplars based on the findings. From a total population of approximately 71,000 senior high school students in Negros Occidental, a sample of 383 respondents was selected. Physical activity served as the independent variable, while self-concept, health lifestyle, and resilience were treated as dependent variables. Descriptive statistics such as mean and standard deviation were used to determine the levels of the variables, while inferential statistics including t-test for dependent and independent samples, one-way analysis of variance, and Pearson’s r were utilized to test the hypotheses at the 0.05 level of significance. Results revealed that senior high school students generally demonstrated a high level of physical activity, self-concept, health lifesty0le, and resilience. Significant relationships were found among the variables, indicating that greater participation in physical activities is associated with stronger self-concept and healthier lifestyle behaviors. Furthermore, resilience varied significantly according to the levels of physical activity, self-concept, and health lifestyle. Regression analysis indicated that these variables significantly predicted resilience among students.
