Interaction Between Fatness and Fitness on CVD Risk Factors in Asian Youth

Abstract

The purpose of this study was to investigate the effects of fatness and fitness on insulin resistance (IR) and cardiovascular disease (CVD) risk factors among Korean adolescents. A total of 322 male high school students participated Departme nt of Sport and Leisure Studies, Yonsei University, Seoup, Republic of Korea Department of Sport and Leisure Studies, Yonsei University, Seoup, Republic of Korea in the cross-sectional part of the study. To determine the interaction of fatness and fitness levels on IR and CVD risk factors, subjects were stratified into four groups based on their body mass index (BMI) and cardio-respiratory fitness. Subjects who were in the high-fat category had significantly higher IR and CVD risk score than subjects in the low-fat category regardless of their fitness level. Subjects who were in high-fat-high-fit group showed significantly lower IR and CVD risk score than high-fat-low-fit group. Twenty-nine obese and unfit subjects participated in the intervention study. Twelve weeks of exercise training significantly reduced body weight (4.11+/-0.75 kg) and improved VO(2max) which resulted in a significant improvement in IR and CVD risk score (2.16+/-0.62 vs. 0.20+/-0.75). Interestingly, improvement in cardio-respiratory fitness and small reduction in body weight in relatively short-term significantly reduced the CVD risk score to the level of low-fat-low-fit subjects. Our results show the importance of fitness in determining IR and CVD risk factors among obese adolescents.

Prevalence and Associated Factors of Metabolic Syndrome Among South Korean Adults

“…This indicates a need to encourage individuals to participate in low and moderate physical activity to manage MetS. According to many previous studies, physical activity is somewhat important in preventing chronic diseases such as type 2 diabetes and cardiovascular disease (Jekal et al, 2009). Previous studies have also observed that mild or moderate exercise had a more significant effect on reducing the prevalence of MetS and cardiovascular risk factors (Lakka & Laaksonen, 2007;Yu et al, 2009).…”

Collaborative evaluation and management of students’ health-related physical fitness: applications of cluster analysis and the classification tree

“…And BMI was only correlated with sit-and-reach tests in boys (36) . It has been shown there were interactions between fatness and fi tness on CVD risk factors in Asian youth (37) . Therefore, based on the tree structure point of view, our study results may imply that the combination of poor fl exibility and body composition in male adolescent may worsen and contribute to the metabolic risk.…”

Tracking of clustered metabolic syndrome risk factor in Japanese children: 3-year follow-up study

“…These phenomena have been reported in Japanese children [10][11][12] . Furthermore, in previous cross-sectional studies, the risk for MetS has been reported to be associated with fatness and aerobic fitness in European 13) , American 14) , Canadian 15) , Australian 16) , and Asian children [17][18][19] .…”
