Objectives: The purpose of this study is to investigate the effect of exercise load on sleep structure and stress hormone secretion during sleep. Methods: Five male physical education students were included in this study after giving their written, informed consents in the Research Institute for Sports Science at the University of Hanyang. All subjects have performed for at least 3 years in a regular aerobic exercises such as football, basketball, and running. The subjects were divided into three groups ; NOE(non-exercise), MDE(middle duration exercise), LDE(long duration excercise). MDE group maintained a total of 120 min exercise, and LDE group maintained a total of 300 min exercise by football, basketball or badminton. All subjects were acclimatized to the experimental sleep condition by spending one night under expermental conditions, including the placement of an intravenous catheter. During the subsequent night(24:00-08:00), somnopolygraphic sleep recordings were obtained, and blood for measuring growth hormone, cortisol, testosterone, and $\beta$-endorphin was collected every 120 min throughout the night. Blood samples were obtained from prominent forearm veins of subjects. Then, the samples were immediately placed in ice and centrifuged within 10 min at 3000 rpm at $4^{\circ}C$. Statistical analyses were performed using the SPSS/$PC^+$. Data were analyzed by one-way ANOVA with repeated measures. Results: No significant differences among groups were observed in sleep latency, total sleep time, stage 2 sleep, and slow wave sleep. However, daytime exercise produced significant changes in stage 1 sleep, REM sleep, stage 2 sleep latency, REM sleep latency and sleep efficiency. Stage 1 sleep, stage 2 sleep latency, and REM sleep latency significantly increased in LDE compared to those of NOE and MDE groups. But the amount of REM sleep significantly decreased in LDE. Sleep efficiency of MDE was higher than those of NOE and LDE. The blood concentrations of growth hormone, testosterone, and cortisol during night sleep were significantly lower in LDE than in NOE. $\beta$-endorphin concentrations in blood during night sleep were not different among groups. Conclusion: The daytime exercise load was significantly related to sleep structure and stress hormone secretion during night sleep. Long duration exercise showed a harmful effect on sleep structure and hormone secretion. However, middle duration exercise had a beneficial effect on sleep structure and hormone secretion during sleep.

The study examined clinical effect of the 'Sexiang Shuhuo Jing' on serum CK and LDH activities and skeletal muscle ${\alpha}-actin$ mRNA expression concentration 140days after skeletal muscle injury in rats. The clinical research consisted of observing and measuring the serum CK, LDH activities and skeletal muscle ${\alpha}-actin$ mRNA expression, at the time of injury and during recovery. All experimental data were analyzed by repeated measurement with ANOVA on of SPSS(11.5v), accepting level for all significances was above ${\alpha}\;=.05.$ The results were as follows: That skeletal muscle injury in rats there existed a substantial increase serum CK, LDH activities and expression of skeletal muscle ${\alpha}-actin$ mRNA And Sexiang Shuhuo Jing treatment group's serum CK, LDH activities lower and faster recovery than control group. The 1 st day after skeletal muscle injury, Sexiang Shuhuo Jing treatment group's skeletal muscle ${\alpha}-actin$ mRNA expression was much more higher than control group, after 2 day's faster recovery normal level than control group. There existed a substantial increase again serum CK, LDH activities and skeletal muscle ${\alpha}-actin$ mRNA expression 3rd days after injury in control group. But in Sexiang Shuhuo Jing treatment group's can't be found that.
운동량에 따른 수면 중 뇌파 분석과 GH , Cortisol 변화

운동량에 따른 수면 중 뇌파 분석과 GH, Cortisol 변화. 운동과학, 제8권 제2호, 183-196, 1999. 운동량에 따라 수면 중 뇌파 및 GH, cortisol 변화에 미치는 영향을 분석하기 위하여 운동에 적응되어 있는 체육학과생 7명을 대상으로 운동처치를 하지 않은 집단(NOE), 중정도의 운동집단(MDE), 장시간의 운동집단(LDE)을 구성하였다. 그 결과, 운동량에 따른 수면 중 stage-1 sleep 시간은 LDE에서 유의한 증가가 있었으나 stage-2와 SWS(stage 3+4) 시간은 모든 집단간 유의성이 없었다. 또한 운동량에 따라 수면 중 REM 수면시간은 LDE에서 유의한 감소를 보였다. 또한 운동량에 따라 수면 중 GH 총 분비량 및 시간별 농도 변화는 LDE에서 유의한 감소를 보였으나, cortisol 변화에서는 유의성이 없었다. 이와 같이 LDE는 MDE에 비해 수면 중 REM 수면시간이 매우 감소되어 정상적 수면주기를 이루지 못한 것으로 나타났다. 또한 장시간의 과도한 운동은 수면중 GH 분비량을 현저하게 감소시켰는데, 이는 과도한 신체적 스트레스에 의한 수면 질의 저하를 의미한다. 특히 수면 중 대상자들의 동공 움직임, 심전도, 근전도, 호흡량과 동맥혈 산소농도, 코골이, 수면자세, 꿈 등의 분석을 감안하여 종합적으로 분석한 결과, 중정도 운동은 수면의 질을 향상시킬 수 있는 반면, 과도한 운동 자극은 뇌파 형태와 GH 호르몬 변화에서 나타난 바와 같이 수면 효율에 부정적인 영향을 미치는 것으로 나타났다. The Effects of Exercise Load on the Changes of EEG and concentration during Sleep. Exercise Science, 8(2); 183-196, 1999. The purpose of this study is to investigate the effect of exercise load on the changes of EEG and GH, cortisol during sleep. The subjects were divided into three groups; NOE(non exercise), MDE(middle duration exercise), LDE(long duration exercise). During the subsequent night(24:00∼08:00), somnopolygraphic sleep recordings were obtained, and GH, cortisol were measured every 120 min. 1) Stage-2 and SWS time showed no significant differences among groups. 2) Stage-1 and REM sleep showed significant differences among groups. Namely, stage-1 sleep time significantly increased in LDE than NOE, MDE group. But REM sleep time decreased in LDE than NOE, MDE. 3) GH was decreased remarkably in LDE than NOE, MDE group during sleep. However cortisol showed no significant differences among groups. The changes of GH and sleep patterns varied depending on the exercise load. Long duration exercise induced harmful effects on sleep and hormone.
