8주간 유산소운동이 혈중전해질 농도와 혈중pH에 미치는 영향

The effect of aerobic-exercise during 8weeks on blood electrolyte and pH

&nbsp;&nbsp;The purpose of this study is to analyze the electrolyte such as blood ph, Na?, K?, Ca²?, Mg²?, etc on the each stage of pre-exercise, post-exercise, each 5 minute-recovery, 10 minute-recovery &amp; 30 minute-recovery after exercise. For this experiment, 14 male students at the department of athletics in B Information Technology college in Busan was classified into each 7 exercise group and 7 non-exercise group, and after training them on the intensity of 60%HRmax of each subject 3 period a week for 8 consecutive weeks, the experiment was carried out with the same condition as training manner in treadmill.<BR>&nbsp;&nbsp;The results of this study are as follows.<BR>&nbsp;&nbsp;1. Change of Blood Ph Through Aerobic Exercise.<BR>&nbsp;&nbsp;In exercise group and non-exercise group, there was no particular change in Blood Ph between rest before training &amp; the rest after 8 week- training according to t test.<BR>&nbsp;&nbsp;In case of exercise group, after 8 week-training blood ph value was significantly decreased, and at the 30minute-recovery after exercise, ph value was recovered to the degree of rest (p＜.001).<BR>&nbsp;&nbsp;In case of non-exercise group, blood ph indicated significant change as the similar tendency showed in exercise group, at 10 minute-recovery after exercise, blood ph was recovered to the degree of rest. (p＜.001).<BR>&nbsp;&nbsp;The change of ph by period between exercise group and non-exercise group was not significantly different.<BR>&nbsp;&nbsp;2. Change of Blood Electrolyte Through Aerobic Exercise.<BR>&nbsp;&nbsp;1) Change of blood Na? through aerobic exercise.<BR>&nbsp;&nbsp;In exercise group and non-exercise group, the change of Na? between the rest before training and the rest after training was not significantly different according to the result of t test.<BR>&nbsp;&nbsp;In case of exercise group, after performing 8 week-training, Na? value was significantly increased, and at 10 minute-recovery after exercise, Na? value began to recover into the value in rest, and after 30 minute-recovery after exercise, Na? value was recovered into the degree of rest (p＜.05). In case of the change of Na? in non exercise group, after exercise, Na? value was significantly increased in comparison with rest period, and at 5 minutes after exercise, it was recovered into the degree of rest (p＜.01).<BR>&nbsp;&nbsp;The change of Na? by period between exercise group and non-exercise group was not significantly different.<BR>&nbsp;&nbsp;2) Change of Blood K? through aerobic exercise.<BR>&nbsp;&nbsp;In exercise group and non-exercise group, the change of K? in rest before training and the rest after training was indicated that there was no significant difference according to t test.<BR>&nbsp;&nbsp;In case of exercise group, after 8 week training, K? value was significantly increased, and at 5 minute-recovery after exercise, K? value was recovered into the value in rest (p＜.05). K? in non-exercise group was not significantly changed.<BR>&nbsp;&nbsp;3) Change of blood Ca? through aerobic exercise.<BR>&nbsp;&nbsp;In case of exercise group, the change of Ca? in rest before training and the rest after training was not significantly different according to the result of t test. In case of non-exercise group, the change of Ca? in rest before training and the rest after training was significantly different according to the result of t test (p＜.05).<BR>&nbsp;&nbsp;In case of exercise group, after 8 week-training, Ca? value was significantly increased, and at 5 minute- ecovery after exercise, Ca? value began to recover into the degree of rest, and after 30 minute-recovery after exercise, Ca? value was recovered to the degree of rest (p＜.01). In case of the change of Ca? in non-exercise group, after training, Ca? value was significantly increased in comparison with rest period, and at 30 minute-recovery after exercise, Ca? value was recovered into the degree of rest. (p＜.001).<BR>&nbsp;&nbsp;In case of t
