| 摘要: | PURPOSE: To compare body composition and lipid profile among weightlifters, swimmers, long distance runners and sedentary, and to evaluate their cardiovascular risk. METHODS: Thirty-nine elite athletes and nine healthy sedentary (males, 18-25 years) were recruited (weightlifters, n=11; swimmers, n=12, long distance runners, n=16 and sedentary, n=9). Blood pressure was measured in the morning. Fasting venous blood samples were collected for analyzing total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C). Measurements of weight, %body fat and fat-free mass were obtained via multi-frequency bioimpedance analyzer. The correlations and differences of body composition and blood lipid profile among each group were examined by using Pearson product-moment correlation method and one-way ANOVA, respectively. RESULTS: Body weight, percentage body fat and TC of weightlifters were significantly higher than that of swimmers, runners and sedentary (body weight: 83.25 ± 16.15,67.57 ± 4.32, 60.95 ± 2.94, 66.88 ± 8.93 kg, p＜.05; %body fat: 20.90 ± 6.35 v.s. 13.84 ± 4.55, 12.59 ± 1.17 and 16.91 ± 5.58%, p＜ .05; TC: 190.00 ± 39.76 v.s. 157.92 ± 24.07, 158.56 ± 14.35 and 153.11 ± 15.51 mg/dL, p＜.05). HDL-C of sedentary were significantly lower than that of swimmers and runners (50.89 ± 7.98 v.s. 68.75 ± 13.57 and 69.81 ± 13.21 mg/dL, p＜.05). CONCLUSION: Weightlifters had higher body weight, %body fat, resting blood pressure and worse blood lipid profile than swimmers, runners and healthy sedentary, revealed that weightlifters may have higher cardiovascular risk. Runners had the best cardiovascular healthy state among all groups. |
