    Summary

    Multifractal detrended fluctuation analysis (MFDFA) of surface electromyography (EMG) effectively detected neuromuscular changes after warm-up, revealing increased complexity. Stretching exercises did not further alter these multifractal EMG features.

    Area of Science:

    • Biomechanics
    • Neuroscience
    • Physiology

    Background:

    • Surface electromyography (EMG) is crucial for assessing neuromuscular activity.
    • Understanding neuromuscular adaptations to exercise protocols is vital for performance and injury prevention.
    • Multifractal detrended fluctuation analysis (MFDFA) offers advanced methods for analyzing complex biological signals like EMG.

    Purpose of the Study:

    • To apply MFDFA to surface EMG signals to identify neuromuscular alterations following a warm-up and subsequent stretching exercises.
    • To investigate the sensitivity of MFDFA parameters in detecting changes in muscle activity post-exercise.

    Main Methods:

    • Sixteen volunteers participated in two experimental sessions.
    • Surface EMG was recorded from biceps femoris and semitendinosus muscles during maximal voluntary contractions before and after warm-up and stretching (static or neurodynamic).
    • EMG data were analyzed using MFDFA, focusing on the Hurst exponent and multifractal power spectrum.

    Main Results:

    • The Hurst exponent, maximum α, and peak multifractal spectrum values significantly decreased post-warm-up for both muscles.
    • No significant changes in these parameters were observed after static or neurodynamic stretching compared to post-warm-up.
    • The range, width, and asymmetry of the multifractal spectrum showed no significant differences.

    Conclusions:

    • MFDFA of surface EMG is sensitive to neuromuscular changes induced by warm-up procedures.
    • Warm-up increases the multiscale complexity of EMG signals.
    • Subsequent stretching exercises did not induce further significant alterations in the multifractal characteristics of EMG signals.
