Live high/train low: what changes can be expected, what dose is required, and is it preferable to other training models for improving performance in endurance sports such as running, swimming, and cycling?

Anemia is a condition characterized by too few red blood cells, leading to diminished oxygen delivery, which can significantly impact exercise participation and athletic performance. The etiology of anemia is multifactorial. Some forms of anemia develop as a result of deficiencies in specific vitamins and minerals and may be modifiable, whereas other types are inherited disorders. Although nonmodifiable, the latter may be managed with the assistance of trained medical professionals. This article will provide an overview of the pathophysiology associated with common forms of anemia and provide an introduction to diagnostic testing procedures and treatment options. Additionally, the signs and symptoms will be discussed to help strength and conditioning professionals recognize this potentially impactful condition. This article concludes with a discussion of the influence iron deficiency has on sports participation.
