신말연(Shin Mal-Ryun) 한국체육과학회 2010 한국체육과학회지 Vol.19 No.1

The purpose of this study was to offer experimental data about the effects of 8 weeks of ascorbic acid supplementation and yoga exercise on stress hormones. 30 college females were randomly assigned to one of three group, I.e., Group Ⅰ(n=10): placebo(1000㎎/day); GroupⅡ (n=10): ascorbic acid(500㎎/day) and placebo(500㎎/day); Group Ⅲ(n=10): ascorbic acid(1000㎎/day) with yoga exercise 3-4 times per week. The following measurements were made on all subjects before and after 8 week of experiment. Analysis of covariance and bonferroni test were used to determine the statistical significance. There were no significant differences in epinephrine, norepinephrine and glucagon but cortisol were significantly changed(p<.05). In conclusion, 8 weeks’ ascorbic acid supplementation with yoga exercise may be particularly important on stress hormones in college females. Determination of which exercise types, ascorbic acid dosage and fitness status of individuals would produce reproducible ergogenic effects is a logical extension of current research.

신말연(Shin, Mal-Ryun),조정호(Cho, Jung-Ho) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.3

The purpose of this study was to determine the effect of pyridoxine supplementation with ballet exercise on cell blood components osteocalcin(Os), and total cholesterol/high density lipoprotein cholesterol ration(TC/HDL-C ratio) in female ballet dancers. 14 female ballet dancers were participated in 30days study for a double blind and subjects were randomly assigned to one of the three groups, i.e., Group I (n=4): placebo(2.4mg/day); group Ⅱ (n=5): pyridoxine(1.6mg/day); Group Ⅲ(n=5): pyridoxine(2.4mg/day) with ballet exercise 3-5 times per week. Study subjects measured white blood cells(WBC), red blood cells(RBC), hemoglobin(Hb), osteocalcin(Os), and total cholesterol/high density lipoprotein chloesterol ration(TC/HDL-C ratio), before and after the treatment. Analysis of Covariance (ANCOVA), Multiple Range Test(Scheffe), and anaysis of simple regression were used to determine the statistical significance. There were no group differences in the osteocalcin(Os), and total cholesterol/high density lipoprotein cholesterol ratio, and hemoglobin. but WBC and RBC were significantly changed(p〈.05). The result of this study does not lend support to the contention that pyridoxal phosphate intake has much practical impact on ballet exercise performance as a ergogenic acid. However, it does appear that several significant research topics in pyridoxine biochemistry metabolism as well as ballet exercise and nutrition can be explored profitably in the future using experimental designs involving interaction between pyridoxine status and exercise performance.

The purpose of this study was to determine effect of ballet exercise capacity on bone lipoprotein, cell blood components, and body composition in female ballet dancers. 14 female ballet dancers were participated in 30days study for a double blind and subjects were randomly assigned to one of the tow groups, Group I (n=7): 15,000kcal(energy consume volume 500kcal/day); Group II (n=7): 15,000-30,000kcal(500-1000kcal/day) with ballet exercise 3-5 times per week. Study subjects measured white blood cell(WBC), red blood cell(RBC), hemoglobin(Hb), hematocrit, osteocalcin, calium, percent body fat(%), and total body water, before and after the treatment. The scheffe’s multiple range test and analysis of covariance(ANCOVA) were used to determine the statistical significance. There were no group differences in the calcium, red blood cell, white blood cell, hematocrit, and total body water. but osteocalcin, hemoglobin and percent body fat(%) was significantly changed(p〈.05). In conclusion, it appears that exercise volume for 30days turn into osteocalcin, hemoglobin and percent body fat(%) in female ballet dancers. Therefore, an increased exercise capacity is inversely associated with reduced risk of developing osteopenia and body composition in female ballet dancers.

자연과학분야 : 여성 무용전공자들의 영양지식 인지, 식습관, 신체조성 및 건강관련 체력과의 상관관계

신말연 ( Mal Ryun Shin ) 한국무용과학회 2016 한국무용과학회지 Vol.33 No.1

본 연구는 무용전공자 61명을 대상으로 영양지식 인지, 식습관, 신체조성 및 건강관련 체력과의 상관관계를 분석하고 이들 변인들 간의 인과관계를 파악함으로써 규명된 연구결과들을 무용수들의 효율적인 체중관리와 향후의 영양지식의 인지도와 식습관 및 건강관련 체력 향상을 위한 실험적 자료를 제시하는데 연구의 목적이 있다. 연구 대상자는 서울에서 활동하는 무용전공 여대생들을 무선표집(random sampling)하였고 모든 연구 대상자들의 신체적 측정요인으로는 신장, 체중, 체지방률, 신체질량지수(BMI), 기초대사량, 골격근량을 측정하였다(In-Body 520, Biospace Co., Korea). 연구에 사용된 설문지는 Heyward(1997)의 식습관과 Williams(2008)의 영양지식 관련 설문 문항을 기초로 하여 설문지 초안을 작성하였고 건강관련체력요인 측정 종목은 근력, 근지구력, 유연성, 심폐지구력을 측정하였다. 구체적인 통계기법으로는 다중상관분석(analysis of multiple correlation), 단순선형회귀분석(analysis of simple linear regression)을 사용하여, Durbin Watson검증을 통하여 잔차분석을 하였으며, 이때 유의 수준은 .05로 설정하였다. 연구결과는 무용수들의 영양지식 인지도, 식습관과 신체조성 및 건강관련체력의 다중상관관계를 분석한 결과 유의한 차로 나타난 기초대사량, BMI, 식습관을 종속변인으로 골격근량, 기초대사량, BMI을 독립변인으로 한 단순선형 회귀분석에서 각각 0.85, 0.29, 0.76의 설명력(P<.05)을 나타낸 회귀식이 성립됨으로써 여성무용 전공자의 골격근량, 기초대사량, BMI이 유의하게 영향을 미치는 독립변수로 나타났다. 결론적으로 건강관련체력이 식습관과 영양지식 인지도에 미치는 영향은 미비하지만 무용전공자들의 건강관련 체력과 영양지식 수준이 상당히 낮은 수준이고 또한 신체질량지수와 체지방률이 정상임에도 불구하고 섭식장애의 성향을 지니고 있는 무용수들이 다수 있어 건강에 부정적인 영향을 미칠 수 있다고 추정한다. 무용전공자들이 섭식장애까지 이르지는 않았지만 대부분 체중과 체형에 대한 강박관념을 가지고 있어 정확한 영양지식 교육과 올바른 식습관을 수립할 필요가 있다고 사료된다. The purpose of the current study was to investigate the relationship between Eating Habits, Nutrition Knowledge, body composition and health related physical fitness among dance-major female college students. sixty one female university students were recruited in the current study. BMI was calculated with height and weight assessed, health-related physical fitness was assessed, and eating habits(Heyward, 1997) and nutrition knowledge(Williams, 2008) was assessed with questionnaire. Analysis of multiple Correlation, Analysis of Simple liner Regression, and Dubin Watson Test were applied for the statistical analysis using SPSS 17.0 windows. This results showed that skeletal muscle mass was significantly associated with basal metabolic rate(p〈.05), and body mass index was significantly associated with basal metabolic rate(p〈.05), and eating habits was significantly associated with body mass index(p〈.05) in dance-major female college students. In conclusion, though the influence of eating habits and nutrition knowledge affected by health-related physical fitness was not remarkable and body mass index is normal, the level of physical fitness of dance-major female college students was very low and tendency of eating disorder could have bad effects upon dance-major female college students’ health. Therefore, it is necessary to establish a countermeasure that educates them through straight information and Knowledge on desirable weight-control and an attitude for well-balanced diet.
