The strength of the quadriceps muscle of twelve male surfers who practice their sport for more than 10 years was compared with results of 15 male untrained persons. The concentric peak torque of knee extensors was measured every 10 degrees in a range from 90 to 20 degrees isometrically and dynamically with a constant angle velocity of 10 degrees/sec. The difference in torque between the left and the right leg is not significant, but there is a slight dominance in favour of the standing leg. The body weight related strength of the surfers was 3.2 Nm/kg indicating a higher strength characteristic compared to 2.7 Nm/kg of untrained subjects. Moreover the strength values of our group of athletes were above the value of 3 Nm/kg, which is referred to in the literature as representing a good training status. In view of these results it can be concluded that a long-lasting specific training like surfing will change the strength characteristics of the quadriceps muscles, although none of the surfers had undertaken an extensive strength training for the lower extremity.
将12名从事冲浪运动超过10年的男性冲浪者的股四头肌力量与15名未经训练的男性的结果进行了比较。使用等速测力仪，以10度/秒的恒定角速度，在90度至20度的范围内，每10度对等长和动态的膝关节伸展的同心峰值扭矩进行测量。左右腿之间的扭矩差异不显著，但站立腿略占优势。冲浪者与体重相关的力量为3.2牛米/千克，表明与未经训练的受试者的2.7牛米/千克相比，具有更高的力量特征。此外，我们这组运动员的力量值高于文献中提到的代表良好训练状态的3牛米/千克的值。鉴于这些结果，可以得出结论，尽管没有一名冲浪者对下肢进行过广泛的力量训练，但像冲浪这样的长期特定训练会改变股四头肌的力量特征。
