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. VO₂max(㎖/㎏/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.

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.

박상갑(ParkSang-Kab),윤미숙(YoonMi-Sook) 한국체육학회 2001 한국체육학회지 Vol.40 No.1

WHO의 고혈압 분류 I-II에 해당하는 여자 본태성 고혈압 환자 20명을 대상으로 트레드밀을 이용하여 50%HRmax의 운동강도로 주4회, 1회 40분, 16주간을 트레이닝시켜 신체조성, 심폐기능, 혈압조절 호르몬 및 생활만족도에 미치는 영향을 연구하여 다음과 같은 결과를 얻었다.16주간의 유산소트레이닝이 체중과 체지방율을 감소시키고 최대산소섭취량을 유의하게(p<.05)증가시켜서 심폐기능이 향상되었으며, 16주간의 유산소트레이닝 후 수축기혈압과 확장기혈압이 유의하게(p<.05) 감소된 것으로 나타났다.16주간의 유산소트레이닝 후 혈장 노에피네프린, 레닌, 안지오텐신II, 알도스테론, α-ANP의 감소에 의한 혈장량과 심장지수의 감소로 혈압을 강하시키는 것으로 나타났으며, 고혈압 환자에 있어서 유산소트레이닝은 적극적인 삶을 성취하는데 중요한 변인으로서 삶의 질에 긍정적인 영향을 미치는 것으로 나타났다.이상의 결과를 종합하면, 고혈압 환자에 있어서 유산소트레이닝은 혈장량의 감소와 말초혈관저항의 감소로 인해 생리적으로 혈압을 강하시키고 적극적인 삶을 성취하는 중요한 요소가 되어 삶의 질에 긍정적인 영향을 미치는 것으로 나타났다. The purpose of this study was to investigate the changes of body composition, blood pressure, circulorespiratory functions, QOL and hormones related controlling blood pressure after 16weeks aerobic exercise. Subjects were composed of twenty old female hypertensive patients. V˙O2max was determined for each subjects by administering a treadmill exercise test. The exercise intensities are decided by regression equations between %HRmax and speed(m/min). Subjects were trained during 16weeks(50%HRmax, 4 frequencies/week, 1 hour). Paired t-test was used to evaluate the difference of the pre and post training. The 0.05 level of significance was as critical level for this study.The result of this study are as follows ;1. Weight and %fat were decreased and circulorespiratory function was improved because of increasing in VO2max, VO2max/㎏ after 16weeks aerobic training.2. Systolic blood pressure and Diastolic blood pressure were decreased after 16weeks aerobic training.3. As plasma norepinephrine, renin, angiotension II, Aldosterone and α-ANP were decreased, so blood pressure was decreased because of decreasing total peripheral resistance.4. As the important variable to achieve positive life, aerobic training was shown to positive influence on QOL in hypertensive patients.In conclusion, aerobic training was shown to positive influence on QOL because blood pressure was decreased according to decease plasma volume and peripheral vascular resistance and it is to be the important variable to achieve positive life in hypertensive patients.

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 VO₂max(㎖/㎏/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.

고혈압노인의 장수운동프로그램이 산화질소 및 엔도텔린-1 농도에 미치는 영향

김은희(KimEun-hee),홍가람(HongGaram),이슬희(LeeSeul-hee),정현훈(JungHyun-hoon),박상갑(ParkSang-kab) 한국체육학회 2018 한국체육학회지 Vol.57 No.3

이 연구는 복합운동을 이용한 장수운동프로그램이 고혈압노인의 산화질소(nitric oxide) 및 Endothelin-1 (ET-1) 농도에 미치는 영향을 분석하였다. 연구의 대상자는 고혈압 1 단계에 해당되는(수축기 혈압이 140-159 mmHg 또는 이완기 혈압이 90-99 mmHg) 노인을 대상으로 운동그룹 및 통제그룹으로 구분하였다. 운동그룹 대상자들은 주 3회, 총 16주간 운동을 실시하였다. 그 결과 산화질소(nitric oxide) 농도는 운동 후 유의하게(p<.05) 증가하였고, ET-1 농도는 운동 후 유의하게(p<.05) 감소하였다. 이러한 결과는 혈관이완과 혈압조절에 도움을 주는 NO의 혈관기능의 향상 효과이며, 혈관을 수축하여 혈압조절에 부정적인 영향을 미치는 ET-1의 신경내분비계의 작용과 복합적인 생리적 기전이 동시에 작용하여 ET-1과 NO 사이의 균형이 혈관긴장도를 동적 조절한 것으로 판단됩니다. 따라서 고혈압 노인들의 NO의 감소 및 ET-1의 증가를 예방하기 위해서는 운동개입이 중요한 조절인자이며 특히, 본 연구는 운동의 강도와 시간 그리고 기간이 충분히 고려된 결과라 하겠다. This study analyzed the effect of longevity exercise program using combined exercise on nitric oxide (NO) and Endothelin-1 (ET-1) concentration in the hypertensive elderly. The study subjects were divided into the exercise group and the control group for the elderly who had the first stage of hypertension (systolic blood pressure 140-159 mmHg or diastolic blood pressure 90-99 mmHg). Exercise group subjects were exercised three times a week for a total of 16 weeks. As a result, nitric oxide concentration increased significantly(p <.05) after exercise and ET-1 concentration decreased significantly (p<.05) after exercise. These results suggest that the effect of ET-1 on the neuroendocrine system and the complex physiological mechanisms that simultaneously effect blood vessel relaxation and blood pressure control, The balance between ET-1 and NO is thought to dynamically regulate vascular tone. Therefore, the longevity exercise intervention is an important regulator to prevent the decrease of NO and increase of ET-1 in the hypertensive elderly. Especially, the FITT of the longevity exercise program was appropriated for the hypertensive elderly.
