摘要

目的:早启动运动和咖啡因的摄入被认为是提高白天表现和准备的有效策略。然而,这两种策略的并发效应尚不清楚。本研究旨在绘制在单独启动和与咖啡因联合启动后,反向运动跳跃(CMJ)结果、动力学、策略和准备的恢复和表现的日间时间过程。方法:在双盲随机交叉设计中,11名参与者进行了对照、启动练习(priming)和同时摄入咖啡因的启动(primingcafe)。在每个条件前、后、2小时、4小时和6小时评估CMJ指标,并在6小时评估准备程度。结果:在Priming和PrimingCaf条件后6小时,感知到的身体、心理表现能力和激活平衡更高。立即降低跳跃高度(5.45%至6.25%);0页)。PrimingCaf恢复同心脉冲(p > .754);d = -0.03 -0.08),尽管同心平均力/BM较低(p .513;D = 0.15 ~ 0.21)。个体分析显示,一些参与者从两种策略中受益,因为他们在最小的有价值的变化中表现出跳跃高度的增加,而其他人则没有。结论:两种启动条件均在6 h时提高了心理准备程度;然而,似乎有必要考虑个体变化,以实现启动或启动与咖啡因结合对跳跃结果的积极影响。

Time Course of Jump Recovery and Performance After Velocity-Based Priming and Concurrent Caffeine Intake.

Purpose: Morning priming exercise and caffeine intake have been previously suggested as an effective strategy to increase within-day performance and readiness. However, the concurrent effect of both strategies is unknown. The present research aimed to map the within-day time course of recovery and performance of countermovement jump (CMJ) outcomes, kinetics, and strategy and readiness after priming alone and in combination with caffeine. Methods: Eleven participants performed a control, a priming exercise (Priming) and a priming with concurrent caffeine intake (PrimingCaf) in a double-blind randomized, crossover design. CMJ metrics were assessed before, post, and 2 h, 4 h, and 6 h after each condition while readiness was assessed at 6 h. Results: Perceived physical, mental performance capability and activation balance were higher at 6 h after Priming and PrimingCaf conditions. Immediate reductions in jump height (5.45 to 6.25%; p < .046), concentric peak velocity (2.40 to 2.59%; p < .041) and reactive strength index-modified (RSImod) (9.06 to 9.23% p < .051) after Priming and PrimingCaf were observed, being recovered at 2 h (p > .99). Concentric impulse was restored in PrimingCaf (p > .754; d = -0.03 to-0.08) despite lower concentric mean force/BM (p < .662; d = -0.18 to -0.26) as concentric duration was increased (p > .513; d = 0.15 to 0.21). Individual analysis revealed that some participants benefit from both strategies as they showed increases in jump height over the smallest worthwhile change while others did not. Conclusions: Psychological readiness was increased after both priming conditions at 6 h; however, it seems necessary to consider individual changes to achieve the positive effects of the priming or the priming in combination with caffeine on jumping outcomes.

期刊介绍: Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
