황명훈(MyoungHoonHwang) 한국체육학회 2005 한국체육학회지 Vol.44 No.5

The purpose of this study was to investigate the effects of different environment temperature on serum LDH, CK activity and cortisol concentration. Subjects were seven healthy males who not taking any particular physical training.Temperature and humidity was consisted of high temperature(35±0.5°C), normal temperature(20±0.5°C), Low temperature(5±0.5°C) and maintained 50±3% humidity condition. Treadmill exercise maintained 60% VO2max exercise in the chamber. LDH, CK and cortisol concentration were compared between measured time by one-way ANOVA with repeated measure. Differences were considered significant at the 95% level of confidence(p<.05). Serum LDH activity was a significant difference at recovery 15min between group (p<.05), Tukey post-hoc analysis further revealed that LDH activity was significantly greater in high temperature than normal temperature. Serum CK activity was not significant difference. Cortisol concentration was a significant difference at 30min adaptation in the chamber(p<.05), tukey post-hoc analysis further revealed that cortisol concentration was significantly greater in low temperature than high temperature and normal temperature. These finding suggest that exercise is mainly factor of efflux enzyme and high temperature shows complex and additional factor in injury of skeletal muscle.

The purpose of this study was to investigate the ICING Recovery on heart rate, blood lactate and performance skill after 400M running. In this study, The subjects participating were 6male university students. They participated in test of measuring for heart rate, blood lactate at rest, after 400M running, recovery 5min, 10min, 20min, 30min. Blood lactate was measured by YSI-1500 Blood Lactate analyzer and Heart rate was measured by POLAR Heart rate analyzer, Recovery theory were Icing recovery, activity recovery, non-activity recovery. The result of the study were summarized as follows : 1.In the Heart rate, significantly difference 10min of icing recovery, activity recovery, non-activity recovery(P〈.05). at the Heat rate recovery rate, icing recovery was 84.09% activity recovery was 82.51%, non-activity recovery was 76.73%. 2.In the Blood lactate, significantly difference 5min of icing recovery, activity recovery, non-activity recovery(P〈.05). at the Blood lactate rate, icing recovery was 82.93%, activity recovery was 80.05%, non-activity recovery was 54.03%. 3.Comparing with recoding time at first and second 400M running, icing recovery theory was first recorded time 1.05±2.00, second recorded time 1.07±2.63, activity recovery was first recorded time 1.07±2.63, second recorded time 1.13±3.77, non-activity recovery was first recorded time 1.07±1.604 second recorded time 1.15±4.457.

This study is aimed to determine the cardiovascular function response to maximal exercise of chronic low back pain patients(N=13) and normal group(N=13). By using BRUCE PROTOCOL, subjects underwent tredmill exercise test. Their cardiovascular function responses during rest and after maximal exercise were compared The responses were analyzed using t-test for SPSS 7.0 program. The Cardiovascular function variables employed at rest time(Vo2, HR, Vo2/㎏, VE, Vco2,) and all out time(Vo2peak, HRpeak, Vo2peak/㎏,VEpeak, Vco2peak). Result show that : 1. There was no significant difference in Vo2 between chronic low back pain patients and normal group at rest time. However significant difference in Vo2peak was observed after maximal exercise(p$lt;.05). 2. There was no significant difference in HR between chronic low back pain patients and normal group at rest time. No significant difference in HRpeak likewise observed. 3. There was no significant difference in Vo2/㎏ between chronic low back pain patients and normal group at rest time. However significant difference in Vo2peak/㎏ was observed after maximal exercise load(p$lt;.05). 4. There was no significant difference in VE between chronic low back pain patients and normal group at rest time. However significant difference in VEpeak observed after maximal exercise load(p$lt;.05).

The purpose of this study was to investigate the effect of ingesting Rubus Coreanus Miquel flour on body composition, blood lipid, maximum oxygen intake and fatigue of overweight middle-aged women and present potential of Rubus Coreanus Miquel for health supplement. The targets of this study were 14 women who couldn? lose their weight, even if they kept exercising and we started this research after separating them to two groups that are control group 7 women (45.8?.6 yrs, 154.3?.7 cm, 62.4?.1 kg, 32.1?.4 body fat) and trained group 7 women (45.8?.1 yrs, 152.4?.9 cm, 56.2?.3 kg, 31.1?.0 body fat). The result of the research was that weight, body fat, and BMI of the group who ingested Rubus Coreanus Miquel for 20days showed significant decreasing in the statistics and maximum oxygen intake showed highly oxygen inhalation according to increasing training time. There was no significant difference of blood lipid between two groups. The result of research about change of fatigue lactate and ammonia showed that trained group showed decreasing of fatigue compared to control group and present significant difference between two groups. Rubus Coreanus Miquel is estimated that the material has positive influence to weight, maximum oxygen intake and fatigue of overweight middle-aged women according to this study. But blood lipid didn? show significant difference.

The purpose of this study was to investigate the effects of temperature change on serum FFA, serum glucose concentration and energy expenditure during prolonged exercise. All seven healthy males were asked to do exercise at 60% VO2max in the chamber and experimental temperature within the chamber were adjusted to three condition : normal temperature(NT:20±0.5℃)/ low temperature(LT:5±0.5℃), high temperature(HT:35±0.5℃) and 50±3% humidity condition. Each experimental exercise were monitored and analyzed the change of serum FFA, serum glucose and energy expenditure. Serum FFA concentration showed a significant(p<.05) higher value in LT at exercise 30min, post exercise 15min than NT and HI, serum glucose concentration showed a significant(p<.05) higher value in HT at post exercise, recovery 15min, recovery 30min than NT and LT. In summary, LT condition showed energy supply depend on serum FFA, HT condition showed energy supply depend on serum glucose during prolonged exercise.
