Abstract

Objectives: To examine the relationship between gluteal muscle activity and strength and knee and hip biomechanics during single leg loading tasks
Design: Correlation study
Setting: University Biomechanics laboratory
Participants: 34 physically active, healthy participants, (17 males and 17 females).
Main outcome measures: gluteal muscle EMG activity; hip abduction and extension muscle strength; knee and hip angles and moments
Results: In females knee abduction moments and angles were strongly correlated to hip abduction strength across all tasks, whereas in males the relationships were less clear across tasks with both hip abduction strength and gluteus medius EMG activity showing the strongest relationships in specific tasks.
Conclusion: Hip and knee kinetic and kinematic variables related to the development of dynamic knee valgus would appear to be influenced by gluteal muscle strength and EMG activity. The level of influence varies across single leg squatting and landing tasks and varies between genders.
