ABSTRACT Background: Physical fitness is something that needs to be considered by teenagers because it can relate to aspects of their health. Factors of physical fitness can be influenced by several things, such as hemoglobin levels, nutritional status, percent fat, and physical activity.Objectives: The purpose of this study to determine the relationship between hemoglobin levels, nutritional status, percent fat and physical activity with the physical fitness of female adolescents at MAN 2 Kota SemarangMethods: This research was conducted using a cross-sectional design with a total sample of 87 female students. The sample was collected with proportionate stratified sampling. Data on hemoglobin levels were taken from capillary blood which were then measured using the kapiler blood with Point of Care Testing (easytouch GCHB brand), while nutritional status was measured using the BMI/U indicator, percent fat using the BIA tool and physical activity was measured using the IPAQ questionnaire. Bivariate analysis in this study used the Gamma test and multivariate used the ordinal logistic regression test.Results The results of this study showed that the samples had normal hemoglobin levels (67.8%), good nutritional status (79.3%), normal fat percentage (67.8%) and strenuous physical activity (49.4%). The results of the bivariate analysis showed that there was a relationship between hemoglobin level (p<0.001), nutritional status (p= 0.005), percent fat (p<0.001) and physical activity (p<0.001) and physical fitness of female adolescents. Conclusion: There is a relationship between hemoglobin levels, nutritional status, percent body fat and physical activity with the physical fitness of young women and what most influences the physical fitness of young women is nutritional status.Keywords: Hemoglobin level; Nutritional status; Percent fat; Physical activity; Physical fitness.ABSTRAKLatar belakang: Kebugaran jasmani merupakan hal yang perlu diperhatikan oleh remaja karena dapat berhubungan dengan aspek kesehatannya.
