Authors

Background: Adequate iron intake, hemoglobin levels within normal limits, and good nutritional status are needed by adolescents to be able to maintain their physical fitness in order to improve their performance in school. Insufficient iron intake will decrease hemoglobin production. Low hemoglobin levels can interfere with the transport of oxygen throughout the body, resulting in impaired energy metabolism in cells. Abnormal nutritional status will complicate one's mobility or movement in activities, so that it poses a risk to the quality of adolescent physical fitness.
Objectives: The purpose of this experiment is knowing the relationship of iron intake, hemoglobin levels and nutritional status to the physical fitness of young women in MA Al-Irsyad Gajah.

Results: Characteristics of respondents who have less iron intake (41.5%) and good iron intake (58.5%). The majority of respondents had good hemoglobin levels (69.2%). The majority of respondents about nutritional status is normal nutritional status (55.4%). The majority of physical fitness is moderate (60%). The results of the bivariate analysis showed that iron intake and hemoglobin levels were related to physical fitness (p value <0.005).
