Echocardiography. 2007 Oct;24(9):901-10. doi: 10.1111/j.1540-8175.2007.00494.x.
The relationship between relative aerobic power (rel.VO(2)max) as a generally accepted indicator of endurance capacity and certain characteristics of the athlete's heart, such as body-size related (relative) left ventricular (LV) diastolic wall thickness (WTd), internal diameter (LVIDd), muscle mass (MM), WTd/IDd, heart rate (HR), fractional shortening (FS) and E/A ratio, were investigated in 346 young males (18-35 years, 291 athletes of various events and 55 nonathletic control subjects). Rel.VO(2)max was measured by spiroergometry; cardiac characteristics were determined by two-dimensionally guided M-mode and Doppler-echocardiography. When the groups were pooled, correlation of rel.VO(2)max with the cardiac parameters was significant: LVMM.BSA(-1.5)= 0.413, LVWTd.BSA(-0.5)= 0.327, LVIDd.BSA(-0.5)= 0.292, HR =-0.434, E/A = 0.272 (P < 0.001), but no significant relationship was seen with FS and WTd/IDd. In the endurance trained group, rel. VO(2)max correlated significantly with LVMM.BSA(-1.5), LVWT.BSA(-0.5), HR, and E/A, in the ballgame players with LVMM.BSA(-1.5), LVWT.BSA(-0.5), and E/A, in the power-and-sprint event athletes with HR and E/A. In the control group, no significant relationship was observed. Results indicate that in athletes having higher endurance capacity maximal oxygen consumption depends largely on cardiac condition, while in athletes with a lower endurance capacity it can be limited by peripheral conditions.
相对有氧能力（rel.VO₂max）作为耐力能力的一个普遍接受的指标，与运动员心脏的某些特征之间的关系，如与体型相关的（相对）左心室（LV）舒张期壁厚（WTd）、内径（LVIDd）、肌肉质量（MM）、WTd/LVIDd、心率（HR）、缩短分数（FS）和E/A比值，在346名年轻男性（18 - 35岁，291名不同项目的运动员和55名非运动员对照受试者）中进行了研究。Rel.VO₂max通过运动心肺功能测试来测量；心脏特征通过二维引导的M型和多普勒超声心动图来确定。当将这些组合并时，rel.VO₂max与心脏参数的相关性显著：LVMM.BSA⁻¹.⁵ = 0.413，LVWTd.BSA⁻⁰.⁵ = 0.327，LVIDd.BSA⁻⁰.⁵ = 0.292，HR = -0.434，E/A = 0.272（P < 0.001），但与FS和WTd/LVIDd没有显著关系。在耐力训练组中，rel.VO₂max与LVMM.BSA⁻¹.⁵、LVWT.BSA⁻⁰.⁵、HR和E/A显著相关，在球类运动员中与LVMM.BSA⁻¹.⁵、LVWT.BSA⁻⁰.⁵和E/A相关，在力量和短跑项目运动员中与HR和E/A相关。在对照组中，未观察到显著关系。结果表明，在耐力能力较高的运动员中，最大耗氧量很大程度上取决于心脏状况，而在耐力能力较低的运动员中，它可能受到外周状况的限制。
