The aim of this study was to evaluate and compare the hamstring (H) and quadriceps (Q) strength, bilateral difference and balance ratios in female soccer players. Ninety-three athletes from three age groups: under 13 (U13), 15 (U15) and 18 (U18) participated in the study performing isokinetic tests to measure peak torque, total work, average power and torque at 30º of thigh muscles. Conventional strength balance ratios, angle-specific balance ratio and bilateral strength difference were evaluated. There was bilateral strength difference for extensor muscles total work (p = 0.02) in U13 and flexor muscles peak torque (p = 0.02) in U15. All variables were superior in U15 than U13 (p <.05). There was no strength difference between U15 and U18. Balance ratios did not differ between sides or age groups. The study showed that although peak torque values were higher in U15 than in U13, balance ratios were similar.
本研究旨在评估和比较女性足球运动员的腘绳肌（H）和股四头肌（Q）力量、双侧差异和平衡比。93 名运动员来自三个年龄组：13 岁以下（U13）、15 岁（U15）和 18 岁（U18），他们进行了等速测试，以测量大腿肌肉 30°时的峰值扭矩、总功、平均功率和扭矩。评估了常规力量平衡比、角度特异性平衡比和双侧力量差异。在 U13 中，伸肌总功（p = 0.02）和在 U15 中，屈肌峰值扭矩（p = 0.02）存在双侧力量差异。所有变量在 U15 中均优于 U13（p<.05）。在 U15 和 U18 之间没有力量差异。平衡比在两侧或年龄组之间没有差异。研究表明，尽管 U15 的峰值扭矩值高于 U13，但平衡比相似。
