Abstract
PURPOSE: To examine the relationship between fatness, health-related physical fitness, and cardiovascular disease (CVD) risk factors across four cross-tabulated groups in Chinese adolescents.
METHODS: Participants comprised 588 males and 579 females aged 11-18 years from Guangzhou, China. They were cross tabulated into four groups, i.e., Low-fat/Low-fit, Low-fat/High-fit, High-fat/Low-fit, and High-fat/High-fit, using Chinese standard age- and gender-specific waist circumference (WC) and health-related fitness based on the gender-specific 25% values. The classification of health-related fitness is based on composite index of cardiorespiratory fitness, muscular strength, and speed-agility. The CVD risk factors (blood pressure [BP], triglyceride [TG], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], glucose, and a CVD risk score) among four different groups were examined by ANCOVA, controlling for age.
RESULTS: In males, participants in the Low-fat/Low-fit group had lower BP than the High-fat/High-fit group (p<0.05). For both genders, lower BP values were observed in the Low-fat group compared with the High-fat group with same fitness level (p<0.05). Similarly, lower TC, HDL-C, and LDL-C were also found in the Low-fat groups than High-fat groups in males (p<0.05). In general, males and females tend to have lower blood lipids and glucose concentrations in the High-fit groups than Low-fit groups regardless of fatness although none of the differences reached statistical significance. There were linear relationships across groups for the CVD risk score for both males and females (p<0.05). Higher scores were observed in the High-fat group compared with Low-fat group with same fitness level for males (p<0.05).
CONCLUSIONS: Clustering of CVD risk factors was inversely related to WC in Chinese adolescents, and health-related physical fitness may play a positive role in reducing the hazards of abdominal obesity. Copyright © 2016 American College of Sports Medicine
