Abstract

BACKGROUND: Recently there has been a rise in female participation in running yet the female population is under-researched in sport specific research. Locally, many female athletes annually compete in numerous ultra-marathons (> 42 km). OBJECTIVE: This study investigated the importance of Gluteal muscle strength in dynamic pelvic stability of fatigued female endurance road runners. METHODS: Fourteen female endurance runners (age: 38.0 ± 10.12 years, BMI: 21.99 ± 2.37 kg/m2, and VO2max: 40 ± 5.34 ml/min/kg) volunteered for the participation of this study. Through isokinetic testing, muscle strength and fatigability of the Gluteus Maximus, Medius and Minimus was determined. Sign tests compared pelvis stability (unilateral Trendelenburg, Pelvic Bridge test and pelvic stability through a gait analysis) before and after an endurance run on a cambered and flat surface. Participants were divided into two groups based on change in pelvic stability after the fatigue intervention. RESULTS: The unaffected group was moderately younger; lighter in weight and had a lower BMI. Additionally, this group was largely more experienced (p= 0.61, d= 1.341); aerobically fit and ran significantly longer weekly distances (p= 0.002, d= 3.4). There was no statistical difference in isokinetic testing of strength and endurance hip flexion/extension and abduction/adduction between the two groups (p> 0.05). CONCLUSION: In conclusion, the group that was more experienced and ran longer weekly distances showed no change in pelvic stability after an endurance run. However, the group that showed changes in pelvic stability suggests that fatigue could be a contributing factor to pelvic compensation. It is recommended that female endurance runners incorporate strength training to strengthen the Gluteal and Hip Flexor muscle groups to reduce pelvic compensation.

臀肌力量在疲劳女子耐力公路跑者骨盆动态稳定性中的重要性

背景：近年来，女性参与跑步的人数有所增加，但在体育专项研究中，对女性人群的研究不足。在当地，许多女运动员每年都会参加许多超级马拉松比赛（＞42公里）。目的：本研究探讨了臀肌力量在疲劳女性耐力公路跑者骨盆动态稳定性中的重要性。方法：14名女性耐力跑者（年龄：38.0±10.12岁，BMI：21.99±2.37 kg/m2，VO2max:40±5.34 ml/min/kg）自愿参与本研究。通过等速测试，测定了大、中、小臀肌的肌力和疲劳能力。体征测试比较了在弯曲平坦表面上进行耐力跑前后的骨盆稳定性（单侧Trendelenburg、骨盆桥测试和通过步态分析的骨盆稳定性）。根据疲劳干预后骨盆稳定性的变化，参与者被分为两组。结果：未受影响组年龄适中；体重较轻，BMI较低。此外，这一组的经验更丰富（p=0.61，d=1.341）；两组在力量和耐力髋关节屈曲/伸展和外展/内收的等速测试中没有统计学差异（p>0.05）。结论：总之，经验更丰富、每周跑得更远的那一组在耐力跑后骨盆稳定性没有变化。然而，显示骨盆稳定性变化的小组表明，疲劳可能是骨盆补偿的一个促成因素。建议女性耐力跑者进行力量训练，以增强臀肌和髋屈肌群，减少骨盆补偿。

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
