Flywheel resistance training devices (FRTD) is shown effective in improving strength, sprinting, jumping and changes of direction (COD) performance in male soccer players, however, this is not elucidated in female soccer players. We aimed to assess the effect of FRTD on these physical abilities in females soccer players. 24 professional female soccer players (age: 20.4 ± 2.6 years) were randomly assigned to a flywheel training group (FWTG) that trained twice a week for 6 weeks on a rotary inertia device with an initial volume of 3 sets of 6 repetitions and an inertia of 0,025 kg · m, increasing intensity and volume or a control group (CG) that did not performed any additional resistance training program. Concentric peak torque of the knee extensors (CONEXT) and flexors (CONFLEX), eccentric peak torque of the knee extensors (ECCEXT) and flexors (ECCFLEX) at 60° · s on an isokinetic dynamometer, countermovement jump (CMJ) height, COD and 30-metres sprint were assessed. Significant time by group interactions were found in CONEXT (p = 0.002; η²p = 0.425), CONFLEX (p = 0.037; η²p = 0.22), ECCEXT (p = 0.002; η²p = 0.43) and ECCFLEX (p = 0.008; η²p = 0.334). No time by group effect was found in CMJ (p = 0.061; η²p = 0.182), COD (p = 0.067; η²p = 0.184) or sprint (p = 0.926; η²p = 4.979 · e). In conclusion, 6 weeks of flywheel squat training improved strength (especially eccentric strength) but not soccer-specific abilities such as jumping, changing of direction or sprinting in professional soccer players.
飞轮阻力训练设备（FRTD）已被证明对提高男性足球运动员的力量、短跑、跳跃和变向（COD）能力有效，然而，这在女性足球运动员中尚未得到阐明。我们旨在评估FRTD对女性足球运动员这些身体能力的影响。24名职业女性足球运动员（年龄：20.4±2.6岁）被随机分配到飞轮训练组（FWTG），该组每周训练两次，为期6周，使用初始运动量为3组，每组6次重复、转动惯量为0.025kg·m的旋转惯性设备，并增加强度和运动量，或分配到对照组（CG），该组不进行任何额外的阻力训练计划。在等速测力计上评估了膝关节伸肌（CONEXT）和屈肌（CONFLEX）的向心峰值扭矩、膝关节伸肌（ECCEXT）和屈肌（ECCFLEX）在60°·s时的离心峰值扭矩、反向纵跳（CMJ）高度、COD和30米短跑成绩。在CONEXT（p = 0.002；η²p = 0.425）、CONFLEX（p = 0.037；η²p = 0.22）、ECCEXT（p = 0.002；η²p = 0.43）和ECCFLEX（p = 0.008；η²p = 0.334）中发现了显著的组间时间交互作用。在CMJ（p = 0.061；η²p = 0.182）、COD（p = 0.067；η²p = 0.184）或短跑（p = 0.926；η²p = 4.979·e）中未发现组间时间效应。总之，6周的飞轮深蹲训练提高了力量（尤其是离心力量），但并未提高职业足球运动员的特定足球能力，如跳跃、变向或短跑能力。
