ABSTRACT
Exercise per se does not predispose to hematologic disease states. Although athletes as a group tend to be healthier, they are still susceptible to the same hematologic diseases as nonathletes; however, symptoms from hematologic disturbances may present earlier and at lower severity often manifesting as impaired physical performance.7,8 Maximal or prolonged exertion efforts typically cause transient changes in several hematologic indices. Regular endurance and altitude training generally result in more sustained alterations of hematologic parameters.24 Dietary inadequacies, not uncommon in athletes, may cause hematologic problems due to a decit of calories or critical nutrients.11 This chapter discusses the evaluation, diagnosis, and management of common hematologic disorders identied in the recreational and elite athlete (Table 58.1).
