In numerous investigations, leisure time physical activity (LTPA) participation and physical fitness (PF) are closely related. The purpose of the current study was to determine a correlates of body composition parameters including body mass index (BMI), percent body fat (%body fat), waist circumference (WC), and waist and hip circumference ratio (W/H) between a level of LTPA and PF in male adolescents. Two hundred twenty five Korean male high school students (10th grade) were recruited, and LTPA time were measured with a questionnaire, anthropometric measurements and PF test including 50 m sprint, 1-mile run, standing long jump, sit-up, sit and reach and push-up were performed. There was no statistical association between LTPA and body composition variables while there was statistically significant association between PF and all body composition variables. Participants in a low level of PF were more likely to have higher level of BMI, %body fat, WC and W/H compared to counterparts in a high level of PF. The current study suggests PF is a correlate of body composition in the current population.

The purpose of the current analysis was to examine associations of socio-demographic and environmental factors with walking for exercise in young adults. The sample consisted of 369 females and 315 males, aged 24-30 years (84% white). Telephone or mail survey was used to assess min/wk of walking for exercise (WFE) over the past year and socio-demographic (gender, race, education, income, marital status, smoking and binge drinking) and environmental correlates (home exercise equipments, recreational facilities, neighborhood characteristics). A total of 293 (80%) of females and 148 (48%) of males reported WFE during the past year, and females reported a significantly higher median value of min/wk WFE (59.5 vs. 0.0, p<0.001) than males. Education level and binge drinking habit were significantly associated with participation in walking for exercise. Among individual environmental variables, running shoes, walking trails, enjoyable scenery in neighborhood, frequent observation of others walking/exercising and high crime were significantly associated with participation in walking for exercise. After adjusting for gender, the higher number of home exercise equipments, recreational facilities, neighborhood features and total environmental correlates were significantly associated with higher chance of participation in walking for exercise. In conclusion, developing quality and quantity of environmental variables play significant roles in increasing participation in walking for exercise for health promotion. Further investigation is necessary to identify environmental variables that may promote other leisure time physical activity including vigorous physical activity and strength exercise.

제갈윤석 ( Yoon Suk Jekal ) 한국여가웰니스학회 2011 한국레저사이언스학회지 Vol.2 No.1

많은 사람들이 건강증진을 위해 정기적인 신체활동에 참여하고 있다. 정기적인 신체활동 참여를 통해 체중감소와 건강한 체중을 유지시켜 궁극적으로 현대사회의 가장 큰 문제점인 비만을 해결할 수 있다. 대부분의 사람들은 운동수행 중 체중을 중요한 건강지표로 인식하여 건강상태를 평가하고, 목표체중을 선정하여 운동을 수행하고 있다. 그러나 지나친 체중에 대한 집착은 극단적인 다이어트나 과도한 운동이라는 잘못된 습관을 야기 시킨다. 뿐 만 아니라 건강한 체중감소가 이루어지기 위해서는 장기간의 정기적인 신체활동 참여가 필수적이다. 본 총론은 규칙적인 신체활동 참여를 통해 단기적으로 체력이 증진되고, 대사성질환 위험요인들을 건강한 수준까지 감소되며, 장기적으로 비만도가 건강한 수준까지 감소되기 때문에 지나친 체중조절에 대한 집착보다는 체력증진의 효과를 기대할 것을 제안하고 있다. Participating in regular physical activity is recommended for health promotion. Physical activity participation produces weight loss and healthy body weight maintenance, and essentially the prevalence of obesity decreases. Most people utilize the body weight as physical activity motivation or goal; however, some of them engages in over-exercise or extreme diet in order to extreme weight loss in relatively short period of time. The current review study demonstrates that regular physical activity participation increases health related physical fitness is associated with risk factors of metabolic disorder including blood pressure, glucose, triglyceride, cholesterol and insulin during short period of time, and produces the appropriate amount of weight loss during long period of time.

The purpose of this study was to compare cardiopulmonary function, physical fitness and body composition between the aquatic sports group, and the non-aquatic sports group in female college of Jeju national university. For this experiment, 10 subjects were divided into the non-aquatic sports group(n=5), the aquatic sports(n=5). Cardiopulmonary function(O2max/kg, maximal heart rate, maximal ventilation, anaerobic threshold), physical fitness(strength, muscular endurance, flexibility, balance test), body composition(body weight, body mass index, muscle mass, %fat) of all subjects were measured. Cardiopulmonary function were not shown that there were any difference between groups in all measurement items. However, even though it wasn`t significant, it was shown high in orders of the aquatic soprts group had superior results in factors of O2max/kg, maximal heart rate, maximal ventilation, anaerobic threshold. There was a significant difference between groups in categories of muscular endurance of physical fitness. However, strength, flexibility, balance were not shown that there were any difference between group. Body composition were not shown that there were any difference between groups in all measurement items. In summary, when considering the above results, we concluded that aquatic sports of muscular endurance. but, cardiopulmonary function, strength, flexibility, balance and body composition could improve was somewhat incomplete.

본 연구의 목적은 에너지 소비 및 심폐 능력 향상을 위한 고강도 유산소 운동, 근력 및 근지구력 강화를 위한 서킷 트레이닝, 생활 습관 변화 교육으로 구성된 4주간의 건강증진 중재 프로그램이 과체중 또는 비만 초등학생의 비만도, 체력수준, 인슐린 저항성 및 대사증후군 미치는 영향을 조사하 는데 있다. 과체중 또는 비만 아동 23명을 비만군으로, 정상체중 아동 15명을 정상군으로 선발하였다. 건강증진 프로그램은 총 4주간, 주 3일, 1일 2시간의 운동시간과 1시간의 교육으로 구성되었다. 비만도 (체질량지수, 허리둘레, 체지방률), 체력(근력, 근지구력, 유연성, 심폐체력), 인슐린 저항성 및 대사증후군 위험요인(혈압, 공복 혈당, 중성지방, 고밀도 지단백 콜레스테롤)을 측정하였다. 프로그램 참여 후, 비만도의 유의미한 감소는 없었지만, 비만 아동의 체력수준, 인슐린 저항성 및 대사 증후군 위험 요인은 상당한 개선이 있었다. 결과적으로 여름캠프 참여를 통해 비만 초등학생의 체력수준 향상, 인슐린 저항성 감소 및 대사증후군 위험요인의 빈도 감소에 효과가 있는 것으로 밝혀졌다. The purpose of the current study was to investigate the effects of 4-week health promotion intervention program consisting of high-intensity aerobic exercise to improve energy consumption and cardiorespiratory capacity, circuit training to strengthen muscular strength and endurance and education for lifestyle changes on the obesity level, physical fitness, insulin resistance and metabolic syndrome among overweight or obese elementary school students. Twenty three overweight or obese children as obese group and 15 normal body weight children as normal group were recruited. The health promotion program consisted of two exercise sessions and one education session, 3days/week in 4-week. Obesity level(body mass index, waist circumference, %body fat), physical fitness(muscular strength, muscular endurance, flexibility, cardiopulmonary fitness), insulin resistance(homeostasis model assessment of insulin resistance) and metabolic syndrome risk factors(blood pressure, fasting glucose, triglycerides, high density lipoprotein cholesterol) were measured. There was not significant decrease in obesity level; however, there were significant improvement in physical fitness, insulin resistance and metabolic syndrome risk factors after program participation among obese children. As a result, through participation in the summer camp consisting mainly of exercise, the improvement of the physical fitness level and the decrease of insulin resistance had an effect on the reduction of the metabolic syndrome frequency.
