Abstract

Introduction: The aim of this study was to examine differences between a control warm-up and an Electric Muscle Stimulation (EMS)-induced warm-up in off-road cyclists when examining anaerobic performance measures from a repeated Wingate test (WAnT). Methods: Twelve trained off-road cyclists completed a randomized crossover study (age: 31 ± 10 years, height: 176.79 ± 6.09 cm, body mass: 74.57 ± 4.77 kg). Participants completed two randomized, separate testing sessions involving a control warm-up and an EMS warm-up before undergoing the repeated WAnT, which was used to collect anaerobic performance and physiolo- gical measures during both sessions. High-frequency EMS was applied to the knee extensor muscles for 4 min after a standardized warm-up during the EMS session. Results: Analysis revealed that there were no significant differences between mean power output, peak power output, and percentage decrement between the two sessions. The EMS session resulted in significantly lower average HR values and significantly lower differences in pre-to-post-test blood lactate values when compared to the control session. Discussion: According to the results of this study, an acute application of EMS is not a useful tool for off-road cyclists to improve power output or maintain anaerobic capacity. Hence, its use before competition is questionable.

肌肉电刺激(EMS)在重复Wingate测试中不能改善无氧性能。

简介:本研究的目的是在重复Wingate测试(WAnT)中检查无氧性能测量时，检查越野自行车手的对照热身和肌肉电刺激(EMS)诱导的热身之间的差异。方法:12名训练有素的越野自行车运动员完成了一项随机交叉研究(年龄:31±10岁，身高:176.79±6.09 cm，体重:74.57±4.77 kg)。在进行重复的WAnT之前，参与者完成了两个随机的、独立的测试阶段，包括对照热身和EMS热身，该测试用于收集两个阶段中的无氧性能和生理指标。在EMS过程中进行标准化的热身后，将高频EMS应用于膝关节伸肌4分钟。结果:分析显示，平均功率输出、峰值功率输出和百分比下降在两个会议之间没有显著差异。与对照组相比，EMS组显著降低了平均HR值，显著降低了测试前后血乳酸值的差异。讨论:根据这项研究的结果，EMS的急性应用并不是越野自行车运动员提高功率输出或维持无氧能力的有用工具。因此，在竞争之前使用它是值得怀疑的。

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.
