中文摘要 | 本研究旨在探討攝食高醣配方飲食後,高撞擊運動對血漿鐵濃度之影響。十九位大學男性運動員在攝食高醣配方飲食後(~84%醣類,~13大卡/分斤體重),均先後完成兩項相同之衰竭運動(最大攝氧量85%,斜度10%),期間相隔至少一週。運動前60分鐘開始給予配方飲食,並在半小時內攝食完畢。運動前、中、後取血。衰竭狀態則是根據最大心跳率,呼吸交換率及血漿乳酸值判定,為了增加統計上之靈敏度及正確性,乃合併二次衰竭運動之數據來進行分析。結果發現,衰竭狀態時血漿鐵濃度顯著增加(p < 0.05)。而在恢復期,血漿鐵濃度即又快速地顯著下降(p < 0.05)而回復到其基礎值。顯然高撞擊運動會導致紅血球和/或肌肉細胞之破壞,如此則有可能影響運動耐力,然而,恢復期血漿鐵則快速地被清除了,即時回復血漿鐵質恆定之濃度。但尿液中之鐵含量則由於濃度過低,而無法測得。本研究顯示,任何足部劇烈撞擊地面之運動易造成血球和/或肌肉細胞之破壞,故宜在日常飲食中加強鐵質營養。 |
英文摘要 | This study was conducted to investigate the effect of high impact exercise on the plasma iron concentration in college athletes fed a high carbohydrate (CHO) diet. Nineteen male college athletes completed two identical exhaustive exercise regimens (85% maximal oxygen consumption [VO2max], 10% grade) after a high CHO diet (~84% CHO, ~13 kcal/kg BW). Diet was given 60 min prior to exercise and ingested within 30 min. Exhaustion was determined by the measurements of maximal heart rate (HRmax), respiratory exchange ratio (RER), and plasma lactate concentration. Blood samples were taken before, during, and after the exercise program. In order to increase the sensitivity and accuracy of the statistical analysis, data from two identical exhaustive exercises were pooled. The plasma iron concentration increase significantly (p < 0.05) during exhaustive stage and returned to its baseline (p < 0.05) in the recovery stage, indicating that high impact exercise caused the rupture of erythrocytes and/or muscle cells, which would in turn affect the athlete’s exercise endurance. During the recovery stage, the clearance of plasma iron occurred rapidly, returning the homeostasis of the plasma iron concentration immediately. Urinary iron concentration, either pre- or post- exercise, was too low to be detected in this study. The results suggest that iron status is critical in athletes undergoing high impact exercise. |
