The purpose of the study was to investigate the changes of blood components, acid-base equibilium and concentration of blood gas during boxing matches. Six varsity boxers were the subjects. The number of the RBC were significantly increased after 1st round (p<0.01) and the magnitude of the increase was reduced in accordance with succeeding rounds. The number of the WBC were significantly increased in accordance with succeeding rounds(p<0.01). The Hematocrit and the concentration of Hemoglobin were significantly decreased because of the increase of the number of RBC and decrease of the MCV (p<0.05). The concentration of the blood glucose were increase in accordance with succeeding rounds and the concentration of the blood glucose were shown the 71% of increase after 3 rounds, and also was significantly increased level than that of rest period. The plasma Albumin and total protein concentration were increased in compare with rest period. The plasma Albumin were significantly increased after 2 round but these were no significant differences in other rounds in contrast with rest period. The pH in the venous blood was significantly decreased in accordance with succeeding rounds(p<0.05), But the magnitude of the increase after 3th round was more higher than after 2nd round. The concentration of the bicarbonate and base excess were significantly decreased (p<0.01) in accordance with decreasing of pH and succeeding rounds. The Pco₂ venous blood was shown more increased after 2nd round, but was shown significant decreasing after 3rd round (p<0.01). The Pco₂ was increased in accordance with succeeding wounds and was significantly increased after 3rd round in Compare with Pco₂ O₂CT and O₂ SAT were increased in accordance with the incresing of Pco₂ succeeding round. The significant increase of O₂SAT in venous blood after 3rd round (p<0.01) was shown nearly the value of Po₂ of artrial blood, but the mechanism was not examinated in this study. The heart rate between rounds was increased in accordance with succeeding rounds, and the heart rate after 3th round was shown the load of maximal exercise(193 bpm).

본 연구에서는 근피로현상을 규명하기 위한 요인으로서 세포막 투과성의 변화를 평가하는것 이었으며,중탄산나트륨 투여가 세포막 투과성의변화에 미치는 영향을 규명하는것이었다. 신체건강한 성인남자 8명이 연구의 피험자로 동원 되었으며 이들은 400m 트랙에서 1500m 최대런닝을 수행하였으며 이후 중탄산나트륨 300mg/kg.wt의 섭취후에 동일한 실험을 반복하여 수행하였다. 중탄산나트륨 투여전 1500m 최대런닝에 따라 Na??(P<0.01) Ca????(P<0.05)은 크게 증가된 수준을 나타내었으나 K??, Glucose, LDH 및 Pi농도는 증가된 수준을 나타내었으나 유의한차(P<0.05)는 없는 것으로 나타났다. 또한 중탄산나트륨 투여후 1500m 최대런닝에 따른 Na??(P<0.0001)과 Pi(P<0.0001) 농도는 크게 증가되었으나 그 밖의 변인에서는 증가된 수준을 유지하였으나 유의한 차 (P<0.05)는 없는것으로 나타났다. 또한 중탄산나트륨 투여 전, 후간 차를 비교하여 보았을때 1500m 런닝직후 Ca????(P< 0.01)에서만 유의한 차를 나타내었으며, 그 밖의 어떠한 변인에서도 유의한차(P<0.05)는 없는 것으로 나타났다. 결론적으로 1500m 최대런닝에 따라 세포막 투과성의 변화는 피로에 기여하는 중요한 요인이 된다는 것을 평가할 수 있었으며, 1500m 최대런닝으로 유발된 세포막 투과성의 변화는 중탄산나트륨 투여에 의해서는 유의한 영향을 미치지 못한다는 결론을 내릴 수 있었다. The purpose of this paper was to estimate the changes of cell membrane permeability as indicator of muscle fatigue, and the effect of sodium bicarbonate ingestion. Eight male was participated as subject of this study. Subjects were performed a 1500m maximal running as control, Also as sodium bicarbonate ingestion(300mg/kg. wt). In the experiment of control, Na?? (p<0.01) and Ca???? (p<0.05) was shown significant differnce follows 1500m running, but was not shown significant difference(p)0.05) in the K??, Glucose, LDH and Pi concentration. In the experiment of NaHCO?? ingestion, Na (p<0.0001) and Pi(p<0.0001) concentration was significantly increased levels, but was not displyed a significant difference(p >0.05) in other factors. Also, only Ca????, Compared before with after of NaHCO?? ingestion, after 1500m maximal running was shown a significant difference(p <0.01), but was not shown a significant difference(p>0.05) in other factors. We concluded that, The changes of cell membrane permeability followed 1500m maximal running estimated as important factors to induce a muscle fatigue. However, the changes of cell membrane permeability was not proved the improved effect as sodium bicarbonate ingestion.

고도로 훈련된 중, 장거리 런너(n=10)를 대상으로 단시간내에 최대상태(Exhaustion)에도달하도록 하는 점증적 트레드밀 운동을 실시 하였을때 혈장의 젖산탈수소효소(LDH)및 젖산탈수소 동위효소(LDH isozyme)를 분석함으로서 운동의 형태에 따른 조직의 상해 및 근섬유동원양상을 평가하고자 안정시와 운동직후 및 회복 30,60분에 주저정맥에서 약 5ml의 혈액을 채혈하였다. LDH활성도는 Beckman paragon법을 이용하여 측정 하였으며, LDH isozyme을 전기영동분리하고 scanning desitometer를 이용하여 상대적 %를 산출 하였다. 중, 장거리 런너들에서 점증적 트레드밀 운동부하후 혈장의 LDH활성도는 안정시에 비해 다소 증가 되었으나 통계적 유의차(p>0.05)는 없는것으로 나타났으며, 회복 30분과 60분에서도 안정시 및 운동직후 수준과 유의한차(p>0.05)는 없는것으로 나타났다. LDH isozyme은 운동직후 H-type(LDH1+2)에서 감소되는 경향을, M-type(LDH3+4+5)에서 증가되는 경향을 나타내였으나 통계적 유의차(p>0.05)는 없는 것으로 나타났으며, 회복의 시간경과에 따라서도 유의한차(p>0.05)는 없는 것으로 나타났다. 이러한 연구결과가 시사하는 바는 혈장의 젖산탈수소효소 및 젖산탈수소 동위효소의 변화는 운동의 형태에 따라 차이를 나타낸다는 것과, 현재에 이용된 트레드밀의 강도와 기간이 이들의 변화를 유발 시키기에는 불충분 하였다는 것으로 결론 지을수 있을 것이다. The pupose of this study was to estimate a damage of tissues and a recruitment patterns of muscle fibers followed exercise types by analyzing the plasma lactate dehydrogenase (LDH) and distribution of lactate dehydrogenase isozymes. The subjects for this study consisted of 10 middle and long distance runners. Venous blood samples of 5ml were collected before and after 2min incremental treadmill exercise, also in the 30,60min of recovery. Total LDH aetivity was examinated by using a Beckman paragon techniques. Also, LDH isozymes was determined to electrophoresis separation by using agarose gel buffered in paragon LD isoenzymes kit. This distribution of LDH isoenzymes was calculated from a relative percentage by scanning densitometer. Plasma total LDH activity after treadmill exercise did not statistically significant. difference(P>.05), and did not differ 30,60 minutes of recovery compared with treadmill exercise before. Distribution of LDH isozymes resulted in decreased of LDH H-type (LDHl+2), whereas LDH M-type(LDH3+4+5) increased, but did not statistically significant difference(P>.05) compared with exercise before. We conclude that Changes of plasma lactate dehydrogenase and lactate dehydrogenase isoenzymes differ as exercise types. And exercise intensity and duration of treadmill used to this research is not suitable to inducing a changes of these enzymes.
