Abstract

Although external (EXT) verbal cues have been shown to improve jump performance, limited research has been conducted in youth athletes. Therefore, the purpose of this study was to investigate how different EXT verbal cue types influenced countermovement jump (CMJ) performance in youth athletes. Ten young trained female athletes (16.80 ± 0.60 years) performed the CMJ using four different EXT verbal cues including external-distal (DIST), external-proximal (PROX), analogy (ANA) and holistic (HOL) as well as a neutral cue (CON). Jump height, reactive strength index modified (RSIMOD), countermovement depth, jump time and force-time measures from eccentric and concentric CMJ subphases were measured. No significant differences between cue types were found for RSIMOD. ANA resulted in significantly higher jump height compared to CON ( g = 0.37). PROX significantly increased jump time ( g = 0.60), concentric time ( g = 0.47) and braking time ( g = 0.52), as well as significantly decreasing eccentric braking mean force ( g = 0.43) and eccentric braking rate of force development ( g = 0.59) compared to CON. Countermovement depth significantly increased when using PROX ( g = 0.60), HOL ( g = 0.46) and ANA ( g = 0.51) compared to CON. These results suggest that compared to a neutral cue, EXT verbal cues result in similar CMJ performance in trained youth athletes. However, PROX verbal cues appear to result in reduced performance in many CMJ force-time measures.

不同语言提示类型对青少年女运动员反身跳跃成绩的影响

尽管外部（EXT）言语暗示已被证明可以提高跳跃成绩，但针对青少年运动员的研究却十分有限。因此，本研究旨在调查不同的外部言语提示类型如何影响青少年运动员的反向运动跳跃（CMJ）成绩。十名训练有素的年轻女运动员（16.80 ± 0.60 岁）使用四种不同的 EXT 语言提示（包括外部-远端（DIST）、外部-近端（PROX）、类比（ANA）和整体（HOL））以及中性提示（CON）进行了 CMJ。测量了跳跃高度、修正的反应力量指数（RSIMOD）、反运动深度、跳跃时间以及偏心和同心CMJ子阶段的力-时间测量值。在 RSIMOD 方面，不同提示类型之间没有发现明显差异。与 CON 相比，ANA 能明显提高跳跃高度（g = 0.37）。与 CON 相比，PROX 能明显增加起跳时间（g = 0.60）、同心时间（g = 0.47）和制动时间（g = 0.52），并能明显减少偏心制动平均力（g = 0.43）和偏心制动力发展率（g = 0.59）。与 CON 相比，使用 PROX ( g = 0.60)、HOL ( g = 0.46) 和 ANA ( g = 0.51) 时，反向运动深度明显增加。这些结果表明，与中性线索相比，EXT 语言线索在训练有素的青少年运动员中能产生相似的 CMJ 成绩。然而，PROX言语暗示似乎会降低许多CMJ力量-时间测量的成绩。

期刊介绍： The International Journal of Sports Science & Coaching is a peer-reviewed, international, academic/professional journal, which aims to bridge the gap between coaching and sports science. The journal will integrate theory and practice in sports science, promote critical reflection of coaching practice, and evaluate commonly accepted beliefs about coaching effectiveness and performance enhancement. Open learning systems will be promoted in which: (a) sports science is made accessible to coaches, translating knowledge into working practice; and (b) the challenges faced by coaches are communicated to sports scientists. The vision of the journal is to support the development of a community in which: (i) sports scientists and coaches respect and learn from each other as they assist athletes to acquire skills by training safely and effectively, thereby enhancing their performance, maximizing their enjoyment of the sporting experience and facilitating character development; and (ii) scientific research is embraced in the quest to uncover, understand and develop the processes involved in sports coaching and elite performance.
