Serum ferritin in young men during prolonged heavy physical exercise
Scandinavian Journal of Haematology
|September 1, 1981
Summary
Strenuous physical activity significantly elevates serum ferritin levels in young men, indicating potential iron release from red blood cells. This increase in ferritin persists even after intense training concludes.
Area of Science:
- Sports Medicine
- Hematology
- Human Physiology
Background:
- Serum ferritin is a key indicator of iron storage in the body.
- Intense physical exertion can impact various physiological markers, including red blood cell integrity.
Purpose of the Study:
- To investigate the changes in serum ferritin levels during and after strenuous ranger training.
- To explore the relationship between ferritin levels, hemoglobin, and bilirubin under extreme physiological stress.
Main Methods:
- Serum ferritin, hemoglobin, and total bilirubin levels were measured in 44 male cadets.
- Measurements were taken during a 4-5 day strenuous ranger training course characterized by heavy activity, sleep deprivation, and caloric deficit.
Main Results:
- Ferritin concentrations showed a consistent increase throughout the training period.
- Significantly elevated ferritin levels were observed 2 days post-training.
- Increased ferritin correlated with decreased hemoglobin and elevated total bilirubin.
Conclusions:
- Strenuous physical activity and associated physiological stress likely lead to red blood cell disintegration.
- Released iron from erythrocytes may stimulate ferritin synthesis in reticuloendothelial cells.
- Elevated serum ferritin serves as a marker of red blood cell breakdown during extreme exertion.
