The effectiveness of 8-week force-velocity optimised training was assessed in highly trained professional rugby league athletes. Players (age 24 ± 3 years; body mass 94.9 ± 21.6 kg; height 181.3 ± 6.0 cm) were strength-matched and assigned to a force-velocity optimised group (OP; = 15) or a general strength-power group (GP; = 14). Tests included 10-m, 20-m sprints, 3 repetition-maximum squat and squat jumps over five load conditions to ascertain vertical force-velocity relationship. ANCOVA revealed there was a group effect for force-velocity deficit ( < 0.001), with the OP two-fold greater than the GP group (OP pre: 51.13 ± 31.42%, post: 62.26 ± 31.45%, GP pre: 33.00 ± 19.60%, post: 31.14 ± 31.45%, < 0.001). There were further group effects for 3RM squat (OP pre: 151.17 ± 22.95 kg, post: 162.17 ± 24.16 kg, GP pre: 156.43 ± 25.07 kg, post: 163.39 ± 25.39 kg, < 0.001), peak power (OP pre: 3195 ± 949 W, post: 3552 ± 1033 W, GP pre: 3468 ± 911 W, post: 3591 ± 936 W, < 0.001), and SJ (OP pre: 39.79 ± 7.80 cm, post: 42.69 ± 7.83 cm, GP pre: 40.44 ± 6.23 cm, post: 41.14 ± 5.66 cm, < 0.001). Prescribing F-V deficit training is superior for improving physical performance within highly trained RL players.
8 周力量-速度优化训练对高度训练有素的职业英式橄榄球运动员的效果进行了评估。球员（年龄 24±3 岁；体重 94.9±21.6 千克；身高 181.3±6.0 厘米）进行力量匹配，分为力量-速度优化组（OP；n=15）或一般力量-功率组（GP；n=14）。测试包括 10 米、20 米短跑、3 次最大深蹲和深蹲跳，共 5 个负荷条件，以确定垂直力-速度关系。协方差分析显示，力量-速度不足存在组间效应（<0.001），OP 组是 GP 组的两倍（OP 组：51.13±31.42%，后：62.26±31.45%，GP 组：33.00±19.60%，后：31.14±31.45%，<0.001）。3RM 深蹲（OP 组：151.17±22.95 千克，后：162.17±24.16 千克，GP 组：156.43±25.07 千克，后：163.39±25.39 千克，<0.001）、峰值功率（OP 组：3195±949 W，后：3552±1033 W，GP 组：3468±911 W，后：3591±936 W，<0.001）和 SJ（OP 组：39.79±7.80 厘米，后：42.69±7.83 厘米，GP 组：40.44±6.23 厘米，后：41.14±5.66 厘米，<0.001）也存在进一步的组间效应。规定力量-速度不足训练对提高高度训练有素的 RL 运动员的身体素质表现更有效。
