肌肉无力和肌肉不平衡可能导致肌肉肌腱损伤，因为受影响的肌腱单位的能量吸收能力降低。本研究的目的是调查健康女性跑步者（F：n = 26）和患有髌腱病的女性跑步者（PT：n = 20）的大腿肌肉组织的最大力量和力量耐力。主要结局变量为最大同心和偏心峰值扭矩（60度/s）和同心腘绳肌-股四头肌商（HQQ）。次要结果变量为相对峰值扭矩[Nm/kg]和离心耐力商（计算为1分钟运动结束时与运动开始时的肌肉力量之比），主要结果变量采用Student t检验分析（α = 0.05）。结果表明，受伤和健康女性跑步者在向心和离心峰值扭矩或HQQ方面没有统计学显著差异。次要结果变量也未能显示组间差异。因此，我们得出结论，这些变量是不相关的PT在女性跑步者。
Muscle weakness and muscle imbalance may lead to musculotendinous injuries since the energy absorption capacity of the affected muscle tendon unit is reduced. The purpose of this study was to investigate the maximum strength and strength endurance of the thigh musculature in healthy female runners (F: n = 26) and female runners suffering from patellar tendinopathy (PT: n = 20).Isokinetic strength measurements were recorded in a seated position. Primary outcome variables were maximum concentric and eccentric peak torque (at 60 degrees/s) and concentric hamstrings-quadriceps-quotient (HQQ). Secondary outcome variables were relative peak torques [Nm/kilogram] and eccentric endurance quotient calculated as the ratio of muscle strength at the end of a 1-minute exercise compared to at the beginning of the exercise period.The primary outcome variables were analyzed using Student's t-test for each measure (alpha = 0.05). Secondary outcome variables were qualified descriptively.The results showed no statistically significant differences between injured and healthy female runners in concentric and eccentric peak torque or HQQ. Secondary outcome variables also failed to show inter-group differences. We therefore conclude that these variables are not relevant with respect to PT in female runners.
