This study was to investigate the effect on the body composition and the physical fitness that is worked by the hypodermic fat. In oder to study, we got 90 of the 144 female students, who resides in Pusan area, divided into the under-weight, the normal-weight, and the over-weight group according to he hypodermic fat rate. And then they were inquired with four item of the body composition and six item of physical fitness. After producing the average and standard deviation, and operating the unitary variable analysis to verify the mean deviation we could find the conclusions as follows. 1. The hypodermic fat quantity and hypodemic fat percentage showed the significant difference by the oder of the over-weight, the normal-weight, and the under-weight group in the body composition classified with hypodermic fat. In agility and lbm, the under-weight and normal-weight group was significantly higher than the over-weight group. 2. In the muscular strength, the normal-weight was significantly higher than the under-weight in the physical fitness classified with hypodermic fat. The muscular endurance was significantly higher with order of the under-weight, normal-weight, and over-weight. In the muscular power, the under-weight was significantly higher than the normal-weight and the over-weight. In the balance there were no significant difference in statistics. In agility, the under-weight and the normal-weight was significantly higher than the over-weight. In flexibility, the under-weight and the normal-weight, over-weight was not significantly difference. Therefore, there was a tendency that the higher the hypodermic fat was, the lower the physical fitness in the group of the over-weight, the normal-weight and the under-weight. So, it was recommended that teenagers should improve their physical fitness and decrease their hypodermic fat rate with diet, etc. Also, it was important for us to understand exactly the hypodermic fat rate of the female students, and needs preventing fatness with the exercise program and the diet.

College and other adult gymnasts also are more developed than middle school gymnasts in agility and pliability.

비만중년여성의 저항성 운동 후 회복 방법의 차이가 식욕관련 호르몬과 혈관 염증지표에 미치는 영향

손영진(Son, Young-Jin),오창석(Oh, Chang-Suk),성낙광(Seong, Nak-Kwang),서대윤(Seo, Dae-Youn),이삼준(Lee, Sam-Jun),방현석(Bang, Hyun-seok) 한국체육교육학회 2017 한국체육교육학회지 Vol.22 No.3

본 연구에서는 비만중년여성의 저항운동 후 효과적인 회복방법을 알아보기 위해 걷기, 스트레칭, 사우나 및 안정휴식을 각각 실시한 후 식욕조절 호르몬과 혈중염증지표에 보다 효과적인 회복방법의 형태를 알아보고자 하였다. 대상자는 체지방률 30% 이상의 중년여성 34명을 저항운동 후 회복방법의 차이에 따라 걷기(9명), 스트레칭(9명), 사우나(8명) 및 안정휴식(8명)으로 구분하였다. 저항운동은 주 4회, 총 12주간 실시하였고, 중량은 4집단 모두 1RM의 50%로 하였다. 1-4주는 각 종목별 2set/10회, 5-8주는 2set/12회, 9-12주는 2set/15회 반복하였다. WAG는 4Km/h로 20분간 실시하였고, STG는 20분간 각 부위별로 2종류의 스트레칭을 각각 30초간 실시하였다. SAG는 20분간 사우나를 실시하였고, REG는 앉거나 누운 자세로 영화 및 TV시청, 독서, 장기, 바둑 등의 게임을 실시하였다. 자료처리는 SPSS 19.0 프로그램을 이용하여 공변량 분석을 실시하였다. 연구결과 식욕조절호르몬인 렙틴은 운동전․후 비교에서 WAG, STG, SAG에서 유의한 감소가 나타났다. 그렐린은 WAG, STG, SAG에서 유의한 증가가 나타났다. 집단 간의 차이에서 렙틴은 WAG와 SAG가 STG와 REG보다 낮게 나타났으며, 그렐린은 WAG와 SAG가 REG보다 높게 나타났다. 혈중 염증지표의 운동전․후 비교에서 CRP와 TNF-⍺는 WAG에서 유의한 감소가 나타났다. 집단 간의 차이에서는 WAG가 STG, SAG, REG에 비해 유의하게 낮게 나타났다. 따라서 비만중년여성의 저항운동 후 회복방법에 따라 식욕조절 호르몬과 혈중 염증지표에 영향을 미치는 것으로 판단되며, 보다 적절한 회복을 위한 다양한 유형의 회복방법에 관한 연구가 요청된다. Purpose: The purpose of this study was to identify more effective recovery methods on appetite related-hormones and vascular inflammatory markers(CRP, TNG-⍺) in middle aged obese women. Methods: Thirty-four middle aged obese women (>30% body fat percentage) were randomly divided into four groups: walking group (WAG, n=9), stretching group (STG, n=9), sauna group (SAG, n=8), and rest group (REG, n=8). Resistance training (RT) with 50% of 1 RM was performed four times per week for 12 weeks. The RT was completed 2 set/10 times from 1st to 4th weeks, 2 set/ 12 times from 5th to 8th weeks, 2 set/15 times from 9th to 12th weeks. WAG walked on treadmill at 4㎞/h for 20 minutes. STG conducted 2 types of 30 second stretching on each part for 20 minutes. SAG conducted sauna for 20 minutes. REG broke time for rest with watching TV, reading, and playing games of Go or Korean chess on a sitting or laying position. The statistical analysis was measured using SPSS 19.0. Results: The appetite related-hormones and leptin levels were significantly decrease in WAS, STG, and SAG after training. The Ghrelin level was significantly increased in WAG, STG, and SAG. The leptein level was lower in WAG and SAG than STG and REG. The ghrelin level was higher in WAG and SAG than REG. The CRP and TNF-⍺ levels showed a significant decrease in WAG. The CRP and TNF-⍺ levels were significantly lower in WAG than STG, SAG, and REG. Conclusion: This study suggests that different recovery methods have a different effect on appetite related- hormones and vascular inflammatory markers in middle-aged obese women.

This research let 90 of the 135 male students, who are in the third grade in the high school the Busan, divided into the under-weight, the normal-weight, and the over-weight group, with 30 students in each group, according to the level of the Hypodermic Fat Rate in order to investigate the body composition and Physical Fitness By the hypodermic Fat distribution of the male high School Students, and examined in the body composition 4 and Physical Fitness 6 lists. This shows the following conclusion. After I was produced the average of a dependent variable of the hypodermic fat quantity and rate and standard deviation, to verify the mean deviation, an unitary variable analysis came into effect. This shows the following conclusion. 1. The hypodermic fat quantity and rate shows the obvious difference by order of over-weight, normal-weight, under-weight in the body composition by the hypodermic(PK001), but the lbm quantity and juices doesn't show that statistically(P>.05). 2. The muscular fitness of the over and the norma groups is higher than obvious difference from the former and the latter in the Physical Fitness by the hypodermicfat distribution(PK01). muscular endurance and gility of the under groups is thenormal groups and higher than that of the over one, there is the obvious difference as well(P<.001). muscular power the under groups, normal groups, higher then that of the over one, there is the obvious difference as well(P<.O01). There isn't any difference statistically in balance and flexibility(P>.05). Therefore, among the under-weight, the normal-weight and the over-weight group, because the higher the hypodermic fat rate is, the lower the physical strength of students grows, teenagers should improve their health and decrease their hypodermic fat by doing exercise and a dietary treatment.
