김찬회 ( Chan Hoi Kim ),이한웅 ( Han Woong Lee ) 한국운동생리학회(구 한국운동과학회) 2014 운동과학 Vol.23 No.2

이 연구의 목적은 비만중년여성 16명을 대상으로 지속시간(본 운동 30분, 60분)에 따른 12주간 주 3회 유산소운동(60-65 %HRR의 강도)이 이들의 신체조성, 혈중 지질, 식이 및 대사조절호르몬 농도에 어떠한 변화를 일으키는지 규명하는 데 있다. 그 결과 모든 종속변인에서 집단 × 시기의 교호작용 및 집단 간의 주효과는 일어나지 않았고 체지방량(p<.05), 체지방률(p<.05)과 WHR(p<.05), 혈중 TG(p<.05), TC(p<.01), LDL-C(p<.05), leptin(p<.05) 농도에서 시기에 대한 주효과가 있는 것으로 나타났으며, 개별분석을 통해 체지방량과 체지방률, TC와 leptin 농도가 60분 운동집단만 사전과 비교해 유의하게 감소됨을 알 수 있었다. 다수의 종속변인에서 통계적 유의 차는 없었으나 30분 운동집단에서도 규칙적인 운동에 의해 변화되는 경향성은 확인할 수 있었는데 폐경을 준비하는 이 시기의 중년여성에게 있어 본 운동 30분간의 중강도 유산소운동도 60분행하는 것 만큼 인체에 긍정적인 변화를 가져올 가능성이 있고 그러한 측면에서 이들에게 신체활동 참여는 반드시 시행되어야 하며, 금후 연구에서는 지속시간에 따른 운동 강도, 빈도, 형태, 기간 등을 다양화 한 시도가 필요할 것으로 사료된다. The purpose of this study was to examine the changes of body composition, concentration of blood lipid, diet and metabolic hormone by aerobic exercise durations (30 min, 60 min; 6 0-65 %HRR). Data were collected three times a w eek f or 1 2 weeks. We found results as follows: there was no interaction in any factors between two groups and the periods before and after the exercise. The substantial changes in body fat mass (p<.05), % body fat (p<.05), WHR (p<.05) and concentration of TG (p<.05), TC (p<.01), LDL-C (p<.05) and leptin (p<.05) clearly demonstrated significant effects of the period before and after an aerobic exercise. Moreover, one-hour main exercise group showed more significant decrease in % body fat, TC and leptin concentration in comparison of pre- and post-exercise. In sum, no statistically significant changes were found in many dependent variables; however, the researchers could have found the changing tendency that may be caused by regular exercise. The study, therefore, demonstrated that women beginning menopause can bring as much positive physical changes through regular aerobic exercise, which is recommended by the study, 30 minute in moderate intensity, three times a week for 12 weeks. From this perspective, the women in this period absolutely benefit from participating in physical activities. The findings of this study suggest that further researches should take different approaches and try to find the effect of exercise duration based on exercise intensity, frequency, type, and term.

The effects of the intake of catechin drink on reduction of body fat in the obese as follow: First, the body weight of DG(drinnk-intake group) was not reduced at a significant level after 12 weeks. The body weight of EG(Exercise group) was reduced by 2.16㎏ at a significant level(p<.001) and DEG(drinnk-intake and exercise group) was reduced by 5.35㎏ at a significant level(p<.001) after 12 weeks of the exercise program. Second, the % body fat of DG was reduced by 1.56% at a significant level(p<.05) after 12 weeks. The % body fat of EG was reduced by 1.94% at a significant level(p<.05) and DEG was reduced by 4.65% at a significant level(p<.001) after 12 weeks of the exercise program. Third, the VFA(Visceral Fat Area) of DG was reduced by 12㎠ at a significant level(p<.01) after 12 weeks. The VFA of EG was reduced by 8.56㎠ at a significant level(p<.05) and DEG was reduced by 15.6㎠ at a significant level(p<.01) after 12 weeks of the exercise program. Forth, the SFA(Subcutaneous Fat Area) of DG was reduced by 17.13㎠ at a significant level(p<.001) after 12 weeks. The SFA of EG was reduced by 20.34㎠ at a significant level(p<.001) and DEG was reduced by 32.5㎠ at a significant level(p<.001) after 12 weeks of the exercise program. However, there were no statistically significant differences between the three groups in all factors.

This study is to examine the effect of the functional beverage ingestion on the cardiopulmonary functions and blood lactate by the maximal load of the exercise, and to analyze the difference of the functional variation and the thickness of blood lactate in 30-minute, 20-minute, 10-minute after exercise, right after, during, and before exercise for each group with the ingestion slowly of electrolyte beverage, catechin beverage, and purified mineral water for 300㎖ during 1 minute for 30 minutes before exercise. The results of this study are as follows. As same as the above mentioned, the ingestion of the catechin beverage is more efficient than the electrolyte beverage, in order to remove the lactate in 20- minute after exercise, but the electrolyte beverage is more efficient for reaching to the stability level than catechin beverage. For cardiopulmonary function, the group among ingesting the purified mineral water, catechin beverage, and electrolyte beverage all shows no significant differences. On this situation, it is considered that the effect of ingesting beverage would not influence to cardiopulmonary functions by means of ingesting beverages in 30 minutes before the maximal exercise load, and considered that the before maximal exercise load through the ingestion of beverages would be continued in a long period of time as well.

This study is aimed to inquire the impact of a 12 weeks Ladder interval training on metabolic syndrome risk factors and Hs-CRP, targeting obese middle-aged women. This study intervened the groups by assigning two groups; each consisting 9 people(Control Group; CG, Ladder interval training Group; LG). In an effort to analyze the research results, this study was able to derive the conclusion as shown below by conducting Two-way repeated ANOVA. The analysis result showed that there appeared interaction effect in change of Triglyceride(TG) among the metabolic syndrome risk factors; particularly, TG was significantly lower in after 8 weeks exercise than pre exercise in LG. There were no interaction effects in WHR, SBP, DBP, TC, HDL-C, LDL-C, and Glucose, but ladder interval training showed a more positive improvement in the value of WHR, SBP, OBP, TC, HOL-C, LOL-C, and Glucose after 8 weeks and 12 weeks in comparison to before the exercise, showing a significant difference in time. No interaction effects appeared in Hs-CRP concentration change. Through this, it was found that Ladder interval training suggested a efficient exercise for a metabolic syndrome improvement.
