To examine before and after 6 wks of rehabilitation, the cardiorespiratory fitness, and resting cardiac parameter changes in soccer players having undergone anterior cruciate ligament reconstruction and to assess the benefits of a one leg cycling aerobic training program with the nonsurgical leg during the rehabilitation period.
Twenty-four amateur soccer players took part in this study. The subjects were then randomly assigned to one of two groups--either an individualized one leg cycling aerobic program (training group) or without cardiorespiratory training (control group). The initial evaluation (T1) was carried out the first day of rehabilitation and the final evaluation (T2) within 42 days. Both consisted of resting cardiac echography measurement and maximal graded tests performed with the nonsurgical leg.
For training group, peak power output, peak minute ventilation, the first (VT1), and second (VT2) ventilatory threshold values were significantly (P < 0.05) higher at T2 than at T1 (+13%, +10%, +7%, and +11%, respectively). For control group, peak power output, peak oxygen uptake, peak minute ventilation, and VT2 values decreased significantly at T2 in comparison with T1(-10%, -10%, -12%, and -11%, respectively). After hospitalization, significant reductions in end diastolic volume (T1, 116 +/- 17 ml; T2, 97 +/- 16 ml; P < 0.05) and stroke volume (T1, 75 +/- 14 ml; T2, 59 +/- 12 ml; P < 0.05) were also observed. For training group, the cardiac parameters were similar between T1 and T2.
These results suggest that one leg cycling training during the rehabilitation seems to be an adapted method to stop the effects of hypoactivity.
研究前交叉韧带重建术后的足球运动员在康复6周前后的心肺适能及静息心脏参数变化，并评估康复期间患侧腿进行单腿骑行有氧训练计划的益处。
24名业余足球运动员参与了本研究。受试者随后被随机分为两组——个性化单腿骑行有氧训练组（训练组）或无心肺训练组（对照组）。初始评估（T1）在康复第一天进行，最终评估（T2）在42天内完成。两者均包括静息心脏超声测量以及患侧腿的最大分级测试。
训练组在T2时的峰值功率输出、峰值分钟通气量、第一（VT1）和第二（VT2）通气阈值显著（P<0.05）高于T1（分别增加13%、10%、7%和11%）。对照组在T2时的峰值功率输出、峰值摄氧量、峰值分钟通气量和VT2值与T1相比显著降低（分别降低10%、10%、12%和11%）。住院后，舒张末期容积（T1，116±17ml；T2，97±16ml；P<0.05）和每搏输出量（T1，75±14ml；T2，59±12ml；P<0.05）也显著降低。训练组在T1和T2之间的心脏参数相似。
这些结果表明，康复期间的单腿骑行训练似乎是一种适应的方法，可以阻止活动不足的影响。
