Diary of a long-distance

 February 28, 2008 Thursday Weather: sunny
Today, we launched a school sixth grade the first time since long-distance running events. Students are eager, one to the playground to have to starting a run up, I'm not far behind.
Later, Paozhepaozhe, there is some out of breath, at first I did not take too much notice, thinking better soon. However, later on, also some faint stomach ached, and I can not help but slow down, take a while, feel better when you run again.
back home, I checked with a heart filled with questions about the information, the original is because: the running time, often appear epigastric or left upper abdominal pain, especially in the morning more prone to this phenomenon, medical experts believe that with the human respiratory muscle spasm. the human body's respiratory muscles are the diaphragm and intercostal muscles, diaphragm spasm if it will cause abdominal pain in the upper abdomen or around the phenomenon.
running time, the body's organs will be the transition from resting state to a state of motion, due to strong at this time the body's metabolic processes, the atmosphere and a variety of sudden increase in nutrient requirements, with the body's metabolic products are excreted acceleration, which requires the respiratory and cardiovascular system to improve efficiency, but because of the function of the body's internal organs can not immediately adjust to the desired state, so movement of organs and internal organs there have been in short supply among the contradictions, the body's respiratory system is necessary to accelerate the respiratory rate, increased respiratory depth, in order to meet the needs of the human body.
beginners marathon, often only pay attention to increased respiratory rate, while ignoring the regulation of breathing in depth, resulting in accelerated frequency of respiratory muscle contraction, resulting in respiratory muscle tension, thus causing convulsions, respiratory muscle spasm which can directly stimulate sensory nerve endings, so to engender a feeling of pain.
originally so ah. But what is the solution then? information, said: prevention of exercise-induced pain, the key is to pre-exercise activities to be fully prepared to make to adapt to internal organs.
, I must be fully prepared, running again.
