Comparison of anterior gluteus medius fiber activation during general exercises and PNF exercises

[Purpose] This study compared the activation of anterior gluteus medius fibers during general exercises and proprioceptive neuromuscular facilitation exercises. [Subjects and Methods] The study enrolled 15 healthy adults. The participants performed general hip abductor strengthening exercises and proprioceptive neuromuscular facilitation exercises; during both types of exercise, electromyography activity was recorded. [Results] Greater anterior gluteus medius fiber activation was observed during the proprioceptive neuromuscular facilitation exercises compared with the general hip abductor strengthening exercises. The anterior gluteus medius fibers exhibited greater activity during pattern 2 exercises compared with any other type of exercise. [Conclusion] The results suggest that pattern 2 exercises can selectively activate anterior gluteus medius fibers.
