摘要

背景:本研究的目的是分析五人制足球运动员在单腿桥(SLB)不同变形过程中腘绳肌和腓肠肌外侧的肌肉活动。设计:横断面研究。方法:22名五人制足球运动员(年龄=24.8[3.9]y)自愿参加本研究。参与者在膝盖弯曲45°的情况下进行了3种SLB变体。第一个位置是脚踝处于足底位置并有平坦支撑,第二个位置是踝关节处于背屈(DF)并有脚跟支撑,第三个位置是腕关节处于DF并有脚跟支持的外旋(ER)。Wilcoxon秩和检验评估了具有秩双序列相关效应大小的样本的变量之间的差异。Spearman相关系数用于检验每一块肌肉的最大自主等长收缩百分比与峰值力和力发展率与SLB的3个不同方差的相关性。结果:踝关节DF和ER随足跟支撑的变化在同心BF中产生更高的肌肉活动(P<.01,效应大小[ES]=-0.613);等距(P<.042,ES=-0.494);与足跟支撑的踝关节DF相比,收缩偏心(P<.005,ES=-0.668)。相反,脚踝DF和ER随足跟支撑的变化导致腓肠肌外侧同心肌的肌肉活动减少(P<.001,ES=0.799);等距(P<.003,ES=0.708);和偏心收缩(P<.014,ES=0.589)。结论:在SLB中,DF和ER的位置是训练BF的最佳位置,用平足位置或足跟支撑的DF中的踝关节可以方便地开始BF的康复,并随着足跟支撑在DF和ER中的踝位置而进展。

Does the Position of the Ankle Matter During the Single Gluteal Bridge in Futsal Players? An Electromyographic Analysis.

Context: The aim of this study was to analyze the muscle activity of the hamstring muscles and the lateral gastrocnemius during different variants of the single-leg bridge (SLB) in futsal players.

Design: Cross-sectional study.

Methods: Twenty-two futsal players (age = 24.8 [3.9] y) volunteered to participate in this study. The participants performed 3 variations of the SLB with the knee flexed at 45°. The first position was performed with the ankle in plantar position with flat support, the second with the ankle in dorsiflexion (DF) with heel support, and the third with the ankle in DF and external rotation (ER) with heel support. The Wilcoxon rank-sum test assessed the difference between variables for samples with the rank-biserial correlation effect size. Spearman correlation coefficients were used to examine the associations of the percentage maximal voluntary isometric contraction for each muscle with peak force and rate of force development with 3 different variances of the SLB.

Results: The variation of ankle DF and ER with heel support generated higher muscle activity in BF in concentric (P < .01, effect size [ES] = -0.613); isometric (P < .042, ES = -0.494); and eccentric (P < .005, ES = -0.668) contraction than ankle DF with heel support. In contrast, the variation of ankle DF and ER with heel support generated fewer muscle activity in lateral gastrocnemius in concentric (P < .001, ES = 0.779); isometric (P < .003, ES = 0.708); and eccentric (P < .014, ES = 0.589) contraction than ankle DF with heel support.

Conclusions: The position of DF and ER was the best position in SLB to train the BF. It could be convenient to start rehabilitation of the BF with flat foot postition or ankle in DF with heel support and progress with the position of the ankle in DF and ER with heel support.

期刊介绍: The Journal of Sport Rehabilitation (JSR) is your source for the latest peer-reviewed research in the field of sport rehabilitation. All members of the sports-medicine team will benefit from the wealth of important information in each issue. JSR is completely devoted to the rehabilitation of sport and exercise injuries, regardless of the age, gender, sport ability, level of fitness, or health status of the participant. JSR publishes peer-reviewed original research, systematic reviews/meta-analyses, critically appraised topics (CATs), case studies/series, and technical reports that directly affect the management and rehabilitation of injuries incurred during sport-related activities, irrespective of the individual’s age, gender, sport ability, level of fitness, or health status. The journal is intended to provide an international, multidisciplinary forum to serve the needs of all members of the sports medicine team, including athletic trainers/therapists, sport physical therapists/physiotherapists, sports medicine physicians, and other health care and medical professionals.
