TI  - Status and metabolism of iron in elite sportsmen during a period of professional 
      competition.

AB  - The aim of this study was to determine the effect of both acute exercise and 
      maintained training during a period of competition (3 mo, at the start of the 
      season) on iron metabolism in sportsmen on a professional volleyball team. Twelve 
      sportsmen volunteered for this study. The exercise test was performed on a 
      mechanically braked Monark cycle ergometer and consisted of a triangular 
      progressive test. Three blood samples were obtained in each test: at rest, just 
      after exercise, and after recovery. The following hematological parameters were 
      determined: red blood count (RBC), hemoglobin (Hb) and hematocrit (Hto), mean 
      corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular 
      hemoglobin concentration (MCHC), total proteins (TP), serum iron (Fe) and total 
      iron-binding capacity (TIBC), ferritin (FER), transferrin (TRF), haptoglobin 
      (HPT), and serum cortisol (COR) concentrations. We have found changes in 
      hematological and biochemical variables related to Fe metabolism during the 
      study. The changes observed could be the result of hemoconcentration processes 
      after exercise and, at least in part, to physical stress and muscular damage. We 
      conclude that athletes, after a period of adaptation, with a good plan of 
      work/recovery series, undergo a biological redistribution on hematological and 
      biochemical parameters concerning Fe metabolism during the training and 
      competition period. Also, daily Fe supplementation could restore and mask the 
      true repercussions of maintained training observed in other sports.
