The purpose of this study was to investigate the effects of submaximal exercise on plasma volume and fluid regulatory hormones (ACTH, renin, aldosterone) between ski athletes and non-athletes. A total of 19 male subjects (10 athletes and 9 non-athletes) were participated in the study and their mean age was 22 years old. Submaximal exercise sessions took place on a bicycle ergometer performing 4 minutes of pedalling to reach targeted intensity (75% V·O2peak) and continued during 20 minutes. Blood samples extracted during rest and immediately after exercise. The Plasma volume decreased immediately after exercise in the both groups, but there were no significant difference between the athletes and the non-athletes. The ACTH, renin and aldosterone concentrations were significantly elevated immediately after exercise in the both group. In particular, the increase was significantly greater in the non-athletes compared to the athletes in the blood renin concentration.

이 연구는 운동선수의 월경곤란증이 생리주기(월경기, 분비기)에 따라 난소호르몬(estrogen, progesterone)과 스트레스호르몬 (cortisol, catecholamines에 미치는 영향을 규명하기 위한 것이다. 실험대상자는 21명을 대상으로 월경곤란증의 선수군(n=7), 월경곤란증이 없는 선수군(n=7), 대조군으로 월경곤란증이 없는 일반인 (n=7)으로 구성하였다. 분석결과 난소호르몬의 경우 전체적으로 월경기에 비하여 분비기 높은 수치를 보였으며(p<.001), 집단에 따른 차이는 없었다. 스트레스 호르몬인 cortisol과 epinephrine은 생리주기와 집단에 따른 차이나 변화가 없었다. 그렇지만 norepinephrine의 경우 월경곤란증을 가진 선수군의 월경기 수치가 분비기 수치보다 유의하게 낮았으며, 월경곤란증이 없는 선수군의 월경기 수치보다 유의하게 낮았다(p<.05). 이상의 결과를 요약하면 난소호르몬은 집단에 따른 차이나 변화가 없었으나, 스트레스 호르몬인 norepinephrine의 경우 월경기의 수치가 낮게 나타났다. 보다 명확한 연구의 구명을 위해서는 운동중과 운동형태와 강도, 월경곤란증 정도에 따른 추가적인 연구가 요망된다. The purpose of this study was to investigate the effect of dysmenorrhea on the circulating concentration of ovarian hormone (estrogen, progesterone), cortisol and catecholamines (epinephrine, norepinephrine) during menstrual cycle in athletes. Twelve one females participated in this investigation and composed of athletic group with- and without dysmenorrhea (n=7, respectively), without dysmenorrhea (n=7) and non-athletic control group without dysmenorrhea (n=7). Venous blood sample was obtained during menstrual- and secretory phase. Blood ovarian hormone concentration was significantly increased during secretory phase compared to menstrual phase in all group, but there were no differences among groups. Blood cortisol and epinephrine concentration did not show any change with menstrual cycle also there were no differences among groups. Blood norepinephrine concentration was significantly decreased during menstrual phase compared to secretory phase in athletic group with dysmenorrhea but athletic group without dysmenorrhea and control group did not show any significant change with menstrual cycle. Stress hormone did not show any significant change in all group during menstrual cycle except norepinephrine which revealed significant decrease in menstrual phase compared to secretory phase on athletic group with dysmenorrhea. In conclusion dysmenorrhea can not effect ovarian hormone during menstrual cycle but partially influenced to stress hormone. Further study needed to elucidate the exact mechanism of those hormone about dysmenorrhea related to the degree of dysmenorrhea and correlation between ovarian and stress hormone.
