|
Purpose: This study was conducted to determine how manual resistance (MR) and elastic band (EB) resistanceaffect the muscle activity of the tensor fascia latae (TFL), gluteus medius (Gmed), and gluteus maximus(Gmax) during clam exercise.
Methods: The study included 15 men in their 20s. The muscle activity of the Gmed, Gmax, and TLF wasmeasured during clam exercise using an electromyography device. The clam exercise was randomly performedusing three methods (MR method, EB method, and no resistance method). Statistical verification wasperformed using the repeated measures analysis of variance method.
Results: The muscle activities of the Gmed and Gmax significantly increased during the MR method comparedto in the other methods; furthermore, a significant increase was also observed during the use of EB comparedto no resistance (p<.001). The Gmed/TFL and Gmax/TFL ratios were significantly higher during the MR methodcompared to the other methods (p<.001).
Conclusion: Based on our research results, we suggest that providing MR during the clam exercise can moreeffectively increase the Gmed and Gmax muscle activity compared to the EB method.
