Altitude exposure as a training & iron overload management strategy post leukemia

Area of Science:

• Sports Medicine
• Exercise Physiology
• Hematology

Background:

• Iron overload can occur post-blood transfusion, impacting athlete health and performance.
• Managing iron levels is crucial for athletes, especially those undergoing medical treatments.
• Altitude training is known to affect hematological parameters and athletic performance.

Purpose of the Study:

• To investigate the effects of intermittent altitude exposure on iron stores, hemoglobin mass, and performance.
• To assess iron metabolism and hematological responses in a professional rugby player with iron overload.
• To evaluate the role of altitude exposure in managing iron overload and its impact on athletic capacity.

Main Methods:

• A longitudinal, single case-study design was employed.
• Measurements included serum ferritin, hemoglobin mass, reticulocyte count, blood volume, and training load.
• The study involved a control period with venesections and a study period with intermittent altitude training.

Main Results:

• During altitude exposure, hemoglobin mass and reticulocyte count increased, while serum ferritin declined.
• External training load was lower during altitude exposure, but match statistics improved.
• The player experienced a further decline in serum ferritin during altitude exposure, alongside an increase in hemoglobin mass.

Conclusions:

• Altitude exposure may aid in mobilizing excess iron and increasing hemoglobin mass, potentially benefiting athletes with iron overload.
• Altitude training did not negatively impact the player's performance and may assist in managing total body iron.
• Therapeutic venesections combined with altitude exposure could be a strategy for managing iron overload in athletes.
