Abstract

Context: The hip adductor and abductor muscles play vital roles as stabilizers in the lower-extremity. Their activation during soccer-specific actions is essential, but local muscular fatigue can hinder athletic performance and increase the risk of injury.

Design: This study aimed to observe the variations in frontal plane hip strength in female college soccer players before and after a high-workload soccer-specific training session. Furthermore, the study sought to compare the relative changes in hip strength with the internal and external load measures obtained during that session.

Methods: Twenty female college soccer players participated in a retrospective observational study. Isometric hip adductor and abductor strength were measured before and after a training session in the college spring season. Measurements were taken with a handheld dynamometer (MicroFET 2) while the players were supine. Global positioning system sensors (Catapult Vector S7), commonly worn by players during training sessions and competitive matches, were used to measure external and internal loads. Statistical analyses were performed using paired samples t test to assess hip adductor and abductor strength changes before and after the training session. Spearman rank was used to identify correlation coefficients between global positioning system data and isometric hip strength.

Results: The findings revealed significant decreases in the strength of the right hip adduction (P = .012, -7% relative change), right abduction (P = .009, -7.6% relative change), and left abduction (P = .016, -4.9% relative change) after the training session. Furthermore, relative decreases in hip isometric adduction and abduction strength are related to the distance covered at high speeds.

Conclusion: The results of this study highlight that hip isometric adduction and abduction strength tend to decrease after exposure to high workloads during soccer-specific training.

女大学生足球运动员在高负荷训练后髋关节等长肌力的变化

背景：髋关节内收肌和外展肌作为下肢的稳定器发挥着至关重要的作用。它们在足球特定动作中的激活至关重要，但局部肌肉疲劳会阻碍运动表现并增加受伤风险：本研究旨在观察女大学生足球运动员在高负荷足球专项训练前后髋关节前平面力量的变化。此外，该研究还试图将髋关节力量的相对变化与训练期间获得的内部和外部负荷测量结果进行比较：二十名女大学生足球运动员参加了一项回顾性观察研究。在大学春季赛季的一次训练前后测量了等距髋关节内收和外展力量。使用手持式测力计（MicroFET 2）进行测量时，球员处于仰卧状态。全球定位系统传感器（Catapult Vector S7）用于测量外部和内部负荷，球员在训练和比赛时通常会佩戴该传感器。使用配对样本 t 检验进行统计分析，以评估训练前后髋关节内收肌和外展肌力量的变化。斯皮尔曼等级法用于确定全球定位系统数据与等长髋关节力量之间的相关系数：结果：研究结果表明，在训练课程结束后，右侧髋关节内收（P = .012，相对变化-7%）、右侧外展（P = .009，相对变化-7.6%）和左侧外展（P = .016，相对变化-4.9%）的力量明显下降。此外，髋关节等长内收和外展力量的相对下降与高速行驶的距离有关：本研究的结果表明，在足球专项训练中，髋关节等长内收和外展力量在承受高负荷后往往会下降。

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.
