Why do endurance athletes need blood testing?

  • 26% of ultra-distance endurance athletes have below ideal serum iron levels

  • 56% of 140.6 distance triathletes have reduced iron stores

  • 11% of marathon distance runners have iron overload due to unnecessary supplementation

  • 30% of ultra-distance triathletes have below ideal Folate

  • 6% of ultra-distance triathletes have below ideal Magnesium

  • Up to 50% of female endurance athletes experience anemia during peak training.  The top causes of anemia are (highest to lowest):  iron deficiency, folate/iron mixed deficiency, folate deficiency, folate/B12 deficiency, B12 deficiency, high rate of blood loss. 

  • Up to 50% of ultra-distance endurance athletes will experience "silent anemia", a condition by which hemoglobin and hematocrit are within normal range but are below Athlete Blood Test's ideal ranges.  Silent anemia causes reduced red blood cell production that can lead to performance deficits.

Why is Athlete Blood Test different than other testing agencies and your primary care physician?

  • Athlete Blood Test uses reliable methodology for identifying ideal ranges for an athlete based on frequency, duration, and intensity of training.  The results of the blood tests take into account your current training volume and intensity.  
  • After the results are given, the recommended intervention will take into account your current training volume and intensity whereas results from other agencies and your doctor do not take into account your current fitness and training level.
