Comparison of Different Methods for Identification of Electromyography Threshold in Resistance Exercise
Objective: This study aimed to identify the Electromyographic Threshold (EMGTh) during the dynamic Resistance Exercise, using visual and mathematical identification techniques.
Methods and Results: We evaluated 14 male subjects (22.6 ± 2.1 years) who accomplished an incremental load protocol (10-10% of 1RM) in a half squat guided exercise. The intra-class correlation coefficient (ICC) was used to compare the EMGTh identification methods, in which high reproducibility value was obtained (0.835), confirmed by a moderately strong correlation of 0.721, in general, and yet a pairwise comparison by the Wilcoxon test, which was not identified any difference between the two methods (p> 0.05).
Conclusion: Therefore, the findings of this study show that both methods, visual and mathematical, used to identify the EMGTh, find the same results.
