Anemia is a common disease of the regular physical exercise among the crowd of a higher incidence of adolescent girls more boys. Who participate in sports as usual sense of dizziness, insomnia, anorexia, means that this is more than the body of the symptoms of iron deficiency or anemia. Youth Sports susceptible to anaemia, in the past people would think is its partial eclipse, and other physiological factors. In recent years, domestic and foreign medical research, its causes are complex.
It is well known that iron in the body involved in a major hemoglobin, myoglobin, a variety of hemoglobin and enzymes of cells. Hemoglobin in the blood is the transport of oxygen and carbon dioxide carrier, which combine oxygen in the pulmonary capillaries, delivered to the organization, then the organization of exhaled carbon dioxide to the lungs in vitro; Myoglobin is the muscle of oxygen stored in the premises, in sports The most hypoxia when the release of large amounts of oxygen; oxidase cell hemoglobin and the mitochondria are aerobic of the material essential to generate energy. 67% of the body in charge of distribution of iron in hemoglobin in the delivery of oxygen. 27 percent of iron stored in the liver, spleen and bone marrow, stored in the rest of myoglobin.
The Sports Medicine study found that the body is still in the development of young people, the body of the demand for iron, if not take the initiative, a sense of added iron, the body easily lead to iron deficiency symptoms.
On the other hand, the movement itself will increase the excessive consumption of iron. Physical exercise in human sweat more, the concentration of iron in sweat up to 40 to 60 ng / ml. Sweating more than the loss of iron means increased movement of the muscles increases hemoglobin in the blood and iron content of the high-level than normal, the body of iron requirements corresponding increases red blood cell movement, the life span of more than a movement Fewer people short of its iron metabolism rate and conversion rate will be increased. Therefore, to participate in sports activities particularly vulnerable to the intense physical exercise the body of iron deficiency, there can be serious iron deficiency anemia.
In addition to the above reasons, the recent Japanese experts found that fierce campaign will damage red blood cells or muscle damage caused by the excessive loss of iron, iron deficiency anemia brought symptoms. Chiba Prefecture Cihui Medical University scholar on the North Island in the 1991 Games led to note that the phenomenon of anemia. In recent years, he attended five days a week over the training of young people known as the “campaign group”, known as the addition of “non-family movement,” the survey they conducted found that “people movement” in the symptoms of anemia Many young people, no symptoms of anemia but also the lack of a large number of iron. There is no difference between men and women. Diagnosed as suffering from the lack of anemia and iron 107 “campaign group” Statistics found that many in track and field, basketball and volleyball for young people in the above symptoms. Kitajima explained that the movement stepped on the ground, the soles of the feet by the impact of the blood vessels, or because of muscle movement, red blood cells and vessel walls in the collision, may cause damage to red blood cells. Inadequate preparations and excessive campaign will damage the muscles, causing hemoglobin from the muscle.
Iron plays a crucial role in human health, iron deficiency will inevitably lead to all kinds of adverse reactions. Iron deficiency, aerobic exercise training will decline, the low-oxygen valve; VO2max decreased exercise tolerance decreased accumulation of lactic acid more prone to fatigue, shortness of breath during exercise, the pole appeared earlier, the reaction is strong movement Heart burden, rapid heart rate after exercise, and the slow restoration. The hospital for an examination that the hemoglobin protein and iron levels drop, the level of porphyrin iron increased, and so on. If achieve the degree of anemia, then a slightly activities will be palpitations, shortness of breath, dizziness, eye and conjunctiva, lips, nails pale and serious that the key fingers.
Prevention of anemia caused by movement, the movement is found to have every weakness, memory decline and other symptoms, or urine red, black (red blood cell damage the performance), and other phenomena, we should pay attention to reduce the amount of exercise, to avoid greater intensity Sports, sports to be done before the preparatory activities and organize campaigns, campaigns should wear comfortable shoes to slow down in the face of the impact of foot; more than usual attention to iron intake of high food such as liver, lean meat, beans And green leafy vegetables, etc., may also have iron preparations, such as ferrous gluconate, such as ferrous sulfate. In addition, in particular, should be careful not to artificially dieting.
