운동심리학 : 유산소와 근저항의 복합트레이닝이 비만 청소년의 림프구 및 TNF-a 농도에 미치는 영향
권유찬(KwonYoo-Chan),윤미숙(YounMi-Suk),박상갑(ParkSang-Kab) 한국체육학회 2003 한국체육학회지 Vol.42 No.2
The effects of exercise on immune function unclear. The purpose of this study was to investigate the changes of lymphocyte proliferation, NK cell and TNF-a concentration after 16weeks combined training. Subjects were composed of fourteen obese middle-school students. The training program was separated treadmill running and muscular resistance training. The treadmill running was composed of 60%HRmax, 30 minutes per day, 4 days per week. The muscular resistance training was composed of 60% of 1RM, 40 minutes per day, 4 days per week, 2-way repeated ANOVA was used to evaluate the difference among group and pre and post 16 weeks. The 0.05 level of significance was as critical level for the study.The body weight and %body fat were significantly decreased. And lean body mass and VO<sub>2</sub>max(㎖/㎏/min)was significantly increased after combined training. Also, lymphocyte proliferation and NK-cell were significantly increased after combined training. Both of TNF-α and IL-6 concentration were decreased. And insulin concentration were decreased after combined training.In conclusion, combined training was shown to positive influence on body composition, lymphocyte proliferation and NK cell. In particularly, decreased TNF-α and IL-6 concentration was affect insulin concentration. Therefore, it is maybe thought that combined training was important role for obesity treatment.

운동생리학 : 유산소 및 저항트레이닝이 비만중년여성의 복부지방에 미치는 영향
박상갑(ParkSang-Kab),권유찬(KwonYoo-Chan),윤미숙(YoonMi-Sook) 한국체육학회 2001 한국체육학회지 Vol.40 No.4
평균연령 43.2세의 비만중년여성을 대상으로 24주간 유산소 및 저항트레이닝(1∼12주는 %HRmax의 60%, 13∼24주는 70%로, 30분간 트레드밀 달리기를 실시하였으며, 1∼12주는 최대근력(1 RM)의 60%, 13∼24주는 70%로 반복횟수 10∼12회, 3세트, 60분, 총 90분간 주5회(월,화,수,금,토))이 심폐기능, 혈청지질 및 체지방량과 CT를 이용하여 복부의 피하지방과 내장지방에 미치는 영향을 연구한 결과 다음과 같은 결론을 얻었다.24주간의 유산소 및 저항트레이닝은 체중과 체지방률을 감소시키고, 최대산소섭취량, 체중당 최대산소섭취량을 증가시켜 심폐기능을 향상시켰으며, 총 콜레스테롤, 저밀도지단백 콜레스테롤, 중성지방, 아포지단백B는 유의하게(p<.05) 감소시켰고, 고밀도 지단백 콜레스테롤과, 아포지단백A-I은 유의하게(p<.01) 증가되어 혈청지질이 개선된 것으로 나타났다. 특히 복부비만의 지표인 피하지방량과 내장지방량의 비율이 트레이닝전 0.32에서 24주후 0.27로 유의하게(p<.01) 감소되어 비만 치료에 효과적인 것으로 나타났다.이상과 같이 비만중년여성에 있어서 유산소 및 저항트레이닝은 신체조성의 개선과 심폐지구력을 향상시킬 뿐만 아니라 저밀도 지단백 콜레스테롤, 중성지방의 감소와 고밀도 지단백 콜레스테롤의 증가로 혈청지질성분을 개선시키며 복부의 피하지방과 내장지방을 각각 유의하게(p<.05) 감소시켜 내장지방에 의한 성인병을 예방할 수 있을 것으로 사료된다. The purpose of this study was to investigate the effect of aerobic and resistance training on abdominal fat. Subjects were composed of sixteen obese middle-aged women. Aerobic training was performed 30minutes per day, 5days per week at 60%HRmax during 1∼12weeks and at 70%HRmax during 13∼24weeks. Resistance training was performed 60minutes per day, 5days per week at 60%of 1RM during 1∼12weeks and at 70% of 1RM during 13∼24weeks. The items for abdominal fat volume were measured subcutaneous fat volume(SFV), visceral fat volume(VFV), VFV/ SFV by computed tomography. Paired t-test was used to evaluate the difference of baseline and after 24 weeks aerobic and resistance training. The 0.05 level of significance was as critical level for the study.The results of this study are as follow;1. VO<sub>2</sub>max(㎖/㎏/min) significantly was increased in aerobic and resistance training group.2. T-C, TG, LDL-C, Apo B were significantly decreased and HDL-C, Apo A-Ⅰ were significantly increased in aerobic and resistance training group.3. VFV, SFV and VFV/ SFV were significantly decreased in aerobic and resistance training group.In conclusion, visceral fat was decreased in aerobic and resistance training. So it is maybe thought that long-term aerobic and resistance training improved body composition for obesity treatment.

운동생리학 : 고령자의 일상 보행활동이 골 파라미터에 미치는 영향
박상갑(ParkSang-Kab),권유찬(KwonYoo-Chan),김은희(KimEun-Hee),윤미숙(YoonMi-Suk),박현태(ParkHyun-Tae) 한국체육학회 2005 한국체육학회지 Vol.44 No.3
In this longitudinal study, measurement of osteo sono index (OSI) of the calcaneus were used as indications of bone quality in community-dwelling elderly. To investigate the possibility of using number of steps walked as an indicator of the role played by physical activity on bone quality, we studied the relationship between OSI and the daily ambulation activity. The subjects were 173 community-dwelling elderly aged 65 or above. Daily walking steps were recorded using a pedometer attached the accelerometer for an year outcome measure of physical activity. The daily steps per day of normal and osteopenia group significantly higher (p<0.05) than osteoporotic group. In elderly male, the subjects who have weight-bearing exercise habits had significantly higher (p<0.05) OSI level. In contrast, weight-bearing exercise habits is no relationship with OSI in elderly women. However, there were higher positive relationship (r=0.51, p<0.05) in women. The daily steps per day may be suitable for evaluating the relationship between ultrasonic bone parameter and physical activity in elderly. Not only the daily ambulation activity, but the presence of exercise habit at present and strength of exercise might influence OSI in male. In contrast, the daily ambulation activity of over 7,500 step is helpful to prevent age-related bone loss in elderly women.
