Evidence supports the implementation of concurrent strength and running training, within the same mesocycle, to improve performances in middle- and long-distance events. However, very little is known about the effects of concurrent training cessation. The purpose of this investigation was to describe the effects of 4 weeks of explosive strength training cessation after an 8-week concurrent training protocol. Eight runners completed this study, which first included either plyometric (n = 4) or dynamic weight training (n = 4) in addition to the usual running regimen. Explosive strength training was thereafter interrupted for 4 weeks, during which running sessions were maintained. Participants were tested at baseline, after concurrent training and after concurrent training cessation. The results suggest that the energy cost of running improvements observed after the intervention (−5.75%; 95% CI = −8.47 to −3.03) were maintained once explosive strength training was interrupted (−6.31%; 95% CI = −10.30 to −2.32). The results also suggest that neuromuscular performances were maintained after 4 weeks of concurrent training cessation, especially when tests were specific to the training intervention. Furthermore, a 3000m time trial revealed a similar pattern, with improvements after the concurrent mesocycle (−2.40%; 95% CI = −4.65 to −0.16) and after concurrent training cessation (−4.43%; 95% CI = −6.83 to −2.03). Overall, only trivial changes were observed for aerobic endurance and $\dot{V}{O}_{2}peak$. Together, these results suggest that short-term explosive strength training cessation might be beneficial and could be considered as a taper strategy for middle-distance runners. However, coaches and athletes must interpret these results cautiously considering the study’s low sample size and the very limited available literature in this domain.

短期同时停止训练对中距离跑步者跑步能量消耗和神经肌肉性能的影响

证据支持在同一个中间周期内同时进行力量训练和跑步训练，以改善中长距离赛事的表现。但是，对同时停止训练的效果知之甚少。这项研究的目的是描述在进行为期8周的并发训练后，停止4周爆炸强度训练的效果。八个流道完成这项研究中，其首先包含任一增强式（Ñ = 4）或动态重量训练（Ñ= 4）除了通常的跑步方案。此后，爆发力训练被中断了4周，在此期间保持跑步训练。在基线，同时进行的训练后和同时进行的训练停止后对参与者进行测试。结果表明，一旦中断爆发力训练（-6.31％； 95％CI = -10.30至-，则在干预后观察到的运行改善的能量成本（-5.75％； 95％CI = -8.47至-3.03）得以维持。 2.32）。结果还表明，在同时停止训练4周后，神经肌肉性能得以保持，特别是当测试针对训练干预时。此外，一项3000m的时间试验显示了类似的模式，并发中环周期后有所改善（-2.40％； 95％CI = -4.65至-0。16）和同时停止训练后（−4.43％; 95％CI = −6.83至−2.03）。总体而言，仅观察到有氧耐力和运动的微小变化。$\dot{V}{Ø}_{2}pË\mathrm{一种}ķ$。总之，这些结果表明，短期爆发力训练的停止可能是有益的，并且可以被视为中距离跑步者的一种锥度策略。但是，考虑到这项研究的样本量少且该领域的文献非常有限，教练和运动员必须谨慎解释这些结果。
