目前尚不清楚长期高容量足球训练对青少年足球运动员运动期间左心室（LV）功能的影响。本研究评估了一组训练有素的男性足球运动员（SP）在三年内从青春期前运动员过渡到青春期运动员时，在亚极限运动中左室功能的变化。数据与年龄和性别匹配的娱乐活动对照组（CON）在同一时期进行比较。研究招募了来自两所职业英超青年足球学院的22名SP（研究开始时年龄：12.0±0.3岁）和15名CON（年龄：11.7±0.3岁）。使用二维超声心动图量化在相同的亚最大代谢负荷下运动时的左室功能。（峰值为45%）。在控制生长和成熟后，从第一年开始，SP组的心脏指数（QIndex）与CON组相比存在训练诱导的变化和优势（p < 0.001）。SP组（第一年：6.13±0.76；第二年：6.94±1.31；第三年：7.20±1.81 L/min/m2）与CON组（第一年：5.15±1.12；第二年：4.67±1.04；第三年：5.49±1.06 L/min/m2）相比，SP组(第一年：6.13±0.76；第二年：6.94±1.31；训练诱导的二尖瓣流入速度(E): SP（第一年：129±12；第二年：143±16；第三年：135±18 cm/s）与CON（第一年：113±10；第二年：111±12；第三年：121±9 cm/s）相比，也有类似的增加。这项研究表明，在精英青年SP中，有证据表明，在亚极限运动期间，训练诱导的左心室功能每年增加，而不受生长和成熟的影响。
It is unclear what the effect of long‐term, high‐volume soccer training has on left ventricular (LV) function during exercise in youth soccer players. This study evaluated changes in LV function during submaximal exercise in a group of highly trained male soccer players (SP) as they transitioned over a three‐year period from pre‐adolescent to adolescent athletes. Data were compared to age‐ and sex‐matched recreationally active controls (CON) over the same time period. Twenty‐two SP from two professional English Premier League youth soccer academies (age: 12.0 ± 0.3 years at start of the study) and 15 CON (age: 11.7 ± 0.3 years) were recruited. Two‐dimensional echocardiography was used to quantify LV function during exercise at the same submaximal metabolic load (approx. 45%VO2peak) across the 3 years. After controlling for growth and maturation, there were training‐induced changes and superiority (p < 0.001) in cardiac index (QIndex) from year 1 in the SP compared to CON. SP (year 1: 6.13 ± 0.76; year 2: 6.94 ± 1.31; and year 3: 7.20 ± 1.81 L/min/m2) compared to CON (year 1: 5.15 ± 1.12; year 2: 4.67 ± 1.04; and year 3: 5.49 ± 1.06 L/min/m2). Similar training‐induced increases were noted for mitral inflow velocity (E): SP (year 1: 129 ± 12; year 2: 143 ± 16; and year 3: 135 ± 18 cm/s) compared to CON (year 1: 113 ± 10; year 2: 111 ± 12; and year 3: 121 ± 9 cm/s). This study indicated that there was evidence of yearly, training‐induced increases in left ventricular function during submaximal exercise independent from the influence of growth and maturation in elite youth SP.
