Abstract：
BACKGROUND: Whether cardiovascular (CV) risk factors might impact Left Ventricular (LV) mass in athletes is unknown.
METHODS: The impact of CV risk factors (Total/LDL cholesterol, triglycerides, positive family history, smoking, body fat, blood pressure), constitutional characteristics (age, sex, body mass index) and type of sport was assessed in 1111 Olympic athletes.
RESULTS: Multivariate logistic regression analysis demonstrated a significant impact: BMI ≥ 30 kg/m2 (odds ratio [OR] = 2.8. 95° Confidence Interval [CI] 0.9-13.7; < 0.001; in males); age ≥ 20-year (OR = 2.1, CI 1.4-3.3; p < 0.001) in males; (OR = 2.3; CI 1.4-3.7) in females; systolic blood pressure ≥ 130 mmHg (OR = 1.1, CI 1.01-1.16; p < 0.001) in males; (OR = 1.03; CI 1.01-1.06; p < 0.03) in females; diastolic ≥ 85 mmHg (OR = 1.1, CI 1.03-1.2; p = 0.003) in males; (OR = 1.05, CI 1.02-1.08, p < 0.001) in females. No association was found for family history, smoking, body fat, LDL, total cholesterol, triglycerides. Overall, constitutional traits explain > 60% of the LV mass. Sport explains on average 14%, but large differences existed among disciplines, i.e., endurance showed the highest impact (55%, mixed: 20%, power: 17%, skill: 8%; p < 0.001).
CONCLUSIONS: LV mass in athletes is largely governed by constitutional traits and type of sport, and independent from CV risk factors, except for systolic and diastolic blood pressure. Overall, constitutional traits explain more than 60% of LV mass. The impact of sport is largely different in relation to the discipline, and highest in endurance, moderate mixed and power and mild in skill disciplines.

摘要：
背景：尚不清楚心血管（CV）危险因素是否会影响运动员的左心室（LV）质量。
方法：CV危险因素的影响（总/LDL胆固醇，甘油三酯，积极的家族史，吸烟,身体脂肪,血压），体质特征(年龄，性别,身体质量指数）和运动类型在1111名奥运会运动员中进行了评估。
结果：多变量逻辑回归分析显示出显著影响：BMI≥30kg/m2（比值比[OR]=2.8。95°置信区间[CI]0.9-13.7；<0.001；男性）；男性年龄≥20岁（OR=2.1，CI1.4-3.3；p<0.001）；女性（OR=2.3；CI1.4-3.7）；男性收缩压≥130mmHg（OR=1.1，CI1.01-1.16；p<0.001）；男性；（OR=1.03；女性1.01-1.06；p<0.03；女性1.OR=1.85-1.没有发现家族病史有关联,吸烟,身体脂肪,LDL,总胆固醇,甘油三酯。总的来说,构成性状解释了>60%的LV质量。体育平均占14%，但是学科之间存在很大差异，即，耐力表现出最高的冲击力(55%，混合:20%,功率:17%,技能：8%；p<0.001）。
结论：运动员的左心室质量主要受体质特征和运动类型的支配，独立于CV风险因素，除了收缩压和舒张压.总的来说,构成性状解释了LV质量的60％以上。体育的影响在很大程度上与学科不同，耐力最高，适度的混合和力量，温和的技能学科。
