The purpose of this study was two-fold. First, comparisons on the psychological and physical attributes of normal weight, overweight, and obese children were conducted. Second, the influence of BMI and physical fitness interaction on psychological adaptation in children with obesity was explored. Participants were 245 children between the ages of 9 and 13 years (64.5% males). Data on children considered overweight (n = 45) or obese (n = 78) were gathered from the Korean Obese Children's Physical Activity (KOCPA) projects. Normal weight children (n = 122) were recruited from two Seoul elementary schools. Psychological measurements included Weight Efficacy Life-style Questionnaire (WEL), Physical Self-efficacy Scale (PSES), Child Dietary Self-efficacy Scale (CDSS), Self-concept Inventory (SCI), and the Korean version of the Pediatric Quality of Life Intervention TM Version 4.0 Generic Core Scales (PedsQLTM4.0). BMI (kg/m2) and physical fitness (e.g., aerobic endurance, flexibility) were recorded by experts in exercise physiology. Results showed that children in the high BMI group reported poorer psychological adaption and demonstrated lower physical fitness when compared to the remaining groups. Compared to normal weight children, children considered overweight and obese were found to have lower physical self-efficacy, more negative self-concept, and poorer quality of life. Further, these children also had significantly lower physical fitness levels than their normal weight counterparts. Physical fitness was found to have a significant main effect on weight efficacy (WEL), physical self-efficacy (PSES), and quality of life (PedsQL) in children considered overweight or obese. A significant BMI-physical fitness interaction effect was found for self-concept (SCI) only. Children with higher BMI reported poorer self-concept regardless of fitness level whereas children with lower BMI and higher fitness reported more positive self-concept. Implications and limitations are discussed.

The purpose of this study is to analyze the relationship between students' motivation for participating in leisure sports, students' physical self-concept and the life satisfaction of university students. A total of 419 students were finally analyzed using the convenience sampling method of non-random sampling method after selecting those university students participating in leisure sports at a university located in J district. The results of analysis using SPSS version 21.0 program are as follows. First, there is a positive (+) correlation between the motives of participation of university students and their physical self-concept and satisfaction with university life. Second, the influence of the motive to participate in sports has a positive (+) effect on sports competence and this is affected by health fitness and social interaction, physical activity is affected by pleasure, health fitness, and conditioning, self-esteem, muscular strength is affected by pleasure, health fitness, condition, and society, flexibility is affected by pleasure, health fitness, and society. Third, the influence of participation motive had a positive (+) effect on school satisfaction is affected by pleasure, health fitness, physical condition, external display, socialization, and fellow satisfaction is effected by pleasure and condition.

The purpose of this study is to verify the difference in health and obesity according to water and coffee intake. The study subject is 900 female college students. Physical fitness factors measured in this study were physical strength(grip strength, back muscle strength), muscle endurance (sit-up), Flexibility(Sit & reach) and cardiopulmonary endurance(harvard step). The factors of body composition (intracellular fluid, extracellular fluid, protein, mineral, body water content, muscle mass, lean body mass, body fat mass) and obesity (BMI, body fat percentage, abdominal fat percentage, obesity) were measured with the Inbody equipment. SPSS program was used for all data analysis. Group differences were verified by two-way ANOVA and one-way ANOVA. The results are as follows. There was no interaction effect between water and coffee intake on health and obesity. Therefore, the difference of the dependent variables according to each independent variable was verified. There was no significant difference in physical fitness according to water intake and coffee intake, but there was a significant difference in body composition (intracellular fluid, protein, minerals, body water, muscle mass and lean body mass). Water drinking group more than 7 cups had significantly higher body composition than the 1-4 cups water drinking group. In the case of coffee, the body composition of the 3 cup intake group was significantly higher than that of the none intake group. Obesity was significantly higher than the none intake and 1-2 cup intake groups. Based on the study results, water intake was not related to obesity, but coffee was related. For further studies, it would be better to consider gender and age differences in drinking various beverages such as water and coffee and that would be used to suggest a desirable way of water intake according to individual characteristics of the better health.

This study examined the effects of combined exercise training for preventing falls on the physical performance, falling index, and balance in elderly women. All subjects (N = 32) were recruited and divided randomly to either a combined exercise group (n= 16, EX) or non-exercise control group (n = 16, CON). During 12 weeks of training, the subjects in the EX performed the combined exercise programs (three times/week, 60min/session), and the subjects in the CON maintained their ordinary lives. At the PRE, MID, POST tests, All subjects completed senior fitness tests(dynamic balance, two minutes walking, sit and stand for 30 seconds), tests for falling risk with Tetrax, and tests for posture balance with the spine balance 3D. After the baseline tests, two-way repeated-measures ANOVA with contrast testing was used with SPSS 21.0. Alpha was set to 0.05. In the results, the dynamin balance (p=.001), two minutes walking (p=.001), sit and stand for 30 seconds (p=.001), falling risk (p=.002), and posture balance (p=.034) in the EX were significantly different, but not in the CON. Thus, elderly females who performed combined exercise training for 12 weeks can increase their physical fitness & posture stability and reduce their falling risk.

우리들의 몸은 연령과 함께 쇠약해져 갑니다. 특히 40대, 50대가 되면 자신이 생각하고 있는 이상으로 몸이 쇠약해 있습니다. 유감스럽게도 연령에 의한 체력 저하는 피할 수 없겠지만, 운동부족으로 인한 체력 저하는 적절한 운동으로 예방할 수가 있습니다. 그러나 날마다 운동을 하고 있지 않던 사람이 갑자기 운동을 하기 시작하면 생각지 않았던 부상이나 사고를 일으킬 우려가 있기 때문에 적절한 운동방식, 강도, 빈도, 실시시간에 주의해서 하는 것이 중요합니다. 본 원고에서는 운동을 통한 건강관리에 있어서 부상이나 질병으로 이어지지 않도록 하기 위한 유의점을 구체적인 스포츠를 예로 들면서 해설하였습니다.
