| Abstract | ||||
| Athletes trained for regular intensive endurance exercise often have sports anaemia characterized by low blood iron and haemoglobin levels with decreased aerobic capacity, increases heart rate and elongates the recovery time after exercise. The antimicrobial hepcidin peptide secreted from liver found also to play an important role in iron metabolism leading to iron deficiency. Hepcidin secretion is induced by IL6 elevation after exercise in a case resembles acute phase. This study was proposed to investigate effect of hepcidin on blood iron due to chronic regular intensive program. Eight female athletes from the physical education field games team constituted subjects of this study. Their blood levels of hepcidin, IL6 and iron were measured pre, post and after 6 hours of exercise before and after the program. They were subjected to run on a treadmill at 75% of their VO2max for duration of 60 minutes/day for 5days/week for four weeks. Results revealed both acute and chronic low iron levels but only acute hepcidin and IL6. Theses results conclude that regular intensive training exercise leads to decreased blood iron causing sports anaemia. Also, iron is highly recommended to be supplemented during such periods in any sports program. | ||||
