(i) to compare the effects of two different low-volume resistance priming sessions, where the external load is modified on neuromuscular performance after 6 h of rest; and (ii) to identify the effects on psychological readiness in participants with resistance training experience. Eleven participants (Body mass: 77.0 ± 8.9 kg; Body height: 1.76 ± 0.08 m; Half squat repetition maximum: 139.8 ± 22.4 kg) performed the priming session under three experimental conditions in a randomized and cross-over design during the morning. The control (CON) condition: no resistance training, "optimal load" (OL) condition: two half-squat sets with a velocity loss of around 20% were performed with the "optimal load", and 80% of repetition maximum (80% RM) condition: 2 half-squat sets with a velocity loss of around 20% were performed with the 80% RM. Countermovement jump (CMJ), mean power with OL (MP) and 80% RM (MP), and mean velocity with OL (MV) and 80% RM (MV) were assessed six hours after the intervention. Subjective readiness was also recorded prior to resistance training and evaluation. Significance was set at <0.05. CMJ was higher after the 80% RM intervention than CON (<0.001; Δ = 6.5% [3.4-9.5]). MP and MV seemed to be unaffected by both morning sessions. Higher MP ( = 0.044; Δ = 9.7% [4.0-15.6]; = 0.24[0.10-0.37]) and MV ( = 0.004; Δ = 8.1% [3.2-13.3]; = 0.32[0.13-0.52]) after 80% RM than after CON were observed. No effect was observed on psychological readiness. Conclusions: 80% RM priming session increased CMJ height and the capacity to generate power and velocity under a high-load condition without any effect on psychological readiness.
（i）比较两种不同低容量阻力起动方案的效果，其中在休息 6 小时后，外部负荷会改变神经肌肉性能；（ii）确定在具有抗阻训练经验的参与者中对心理准备的影响。11 名参与者（体重：77.0±8.9kg；身高：1.76±0.08m；半蹲重复最大：139.8±22.4kg）在上午以随机交叉设计进行了 3 种实验条件下的起动方案。对照组（CON）：不进行抗阻训练；“最佳负荷”（OL）条件：进行 2 组半蹲，速度损失约为 20%，使用“最佳负荷”；80%重复最大（80%RM）条件：进行 2 组半蹲，速度损失约为 20%，使用 80%RM。在干预后 6 小时评估了下蹲跳（CMJ）、OL 时的平均功率（MP）和 80%RM（MP）、OL 时的平均速度（MV）和 80%RM（MV）。在抗阻训练和评估前也记录了主观准备情况。显著性设为 <0.05。80%RM 干预后 CMJ 高于 CON（<0.001；Δ=6.5%[3.4-9.5]）。MP 和 MV 似乎不受两个上午方案的影响。80%RM 后 MP（=0.044；Δ=9.7%[4.0-15.6]；=0.24[0.10-0.37]）和 MV（=0.004；Δ=8.1%[3.2-13.3]；=0.32[0.13-0.52]）高于 CON。在心理准备方面没有观察到效果。结论：80%RM 起动方案增加了 CMJ 高度和在高负荷条件下产生力量和速度的能力，而对心理准备没有任何影响。
