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.

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 study was to investigate 1) the obesity rate by a variety of obesity measurements and 2)the prevalence of insulin resistance and metabolic syndrome among overweight or obese children. Two hundred twenty eight overweight or obese children(151 males, 77 females, 4-6th grade) were recruited. The obesity rate, insulin resistance and metabolic syndrome risk factors were assessed and analyzed. The obesity rate were different by obesity measurements including body mass index, waist circumference and percent body fat in this cohort. Participants in obese group were more likely to have significantly higher level of insulin resistance and metabolic syndrome risk factors as compared to those in overweight group with body mass index classification. Sixty one percent participants had insulin resistance, and 15.6% had metabolic syndrome. This study concluded that the child obesity is medically severe since obesity induces metabolic syndrome risk factors and insulin resistance.

본 연구의 목적은 국내 엘리트 대학 선수들이 영국 수영 훈련프로그램 수행 중, 세부 훈련 프로그램에서 제시하는 생리적 지표 수치와 수행 후 측정된 생리적 지표 수치를 비교 분석하는 데 있다. J 대학 수영 선수 6명이 각각 세부 훈련 프로그램에서 제시하는 거리와 기록을 설정하여 수행하였고, 심박수, 혈중 젖산농도, 운동자각도를 측정하였다. 연구 결과, 훈련 프로그램 수행 후 측정된 생리적 지표의 수치는 프로그램에서 제시된 수치와 95%의 일치율이 나타났다. 심폐체력 또는 무산소성파워 수준에 따른 상위 하위 그룹 간의 비교 결과 일치율이 유사하였다. 영국 수영 훈련프로그램 후 생리적 지표의 높은 일치율은 본 프로그램이 국내 수영선수들에게 생리학적으로 효과적인 것으로 제안될 수 있다. 향후 영국 수영 훈련프로그램의 효과를 운동 역학적, 심리학적 측면에서의 검증과 장기적인 효과로써 경기력과의 관계를 규명하는 연구를 제안한다. The purpose of the current study was to investigate the physiological response to British swimming training program and compare between the ranges of physiological responses predicted by that training program and the value of physiological responses after performing the training program among Korean college elite swimmers. Six elite swimmers were recruited in J National University. They performed the detailed training program based on the British Swimming Training Program, and heart rate, blood lactate density and the ratings of perceived exertion were measured as physiological responses. In results, physiological responses of 95% performances by all of participants were consistent with the ranges of physiological responses predicted by British swimming training program. However, there were no significantly different values of physiological responses across the level of cardiorespiratory fitness or anaerobic power. In conclusion, the current study identified that the British Swimming Training Program is physiologically effective among Korean college elite swimmers based on a great unity of physiological responses performed by all of participants and the ranges of physiological responses predicted by training program.
