Introduction

Physical fitness plays an important role in a person's life in carrying out daily activities and is assessed by VO2 max. Anemia interferes with the delivery of oxygen to tissues and causes a reduction in VO2 max. This study aims to analyze the relationship between hemoglobin levels and physical fitness in adolescent girls.

Methods

This research is an analytical observational study with a cross-sectional approach. A total of 102 young women who met the inclusion and exclusion criteria were recruited as subjects in this study. Physical fitness was assessed using the Multistage Fitness Test, and hemoglobin levels were measured using the Point of Care Testing method. Data analysis was carried out using the Spearman correlation test with a significance level of p<0.05.

Results

The average value of hemoglobin levels in adolescent girls is 12.97 g/dL, which is considered normal.  The average physical fitness based on VO2 max prediction is 24.65 ml/kg/minute, which is included in the very poor category. The Spearman test results showed that there was a significant correlation between hemoglobin levels and physical fitness (p=0.001).

Conclusion.

There is a significant correlation between hemoglobin levels and physical fitness in adolescent girls as assessed based on VO2 max predictions.
