MULTİDİMENSİONAL ASSESSMENT OF MUSCLE FATİGUE İN SOCCER PLAYERS (MAMF)
MULTIDIMENSIONAL ASSESSMENT OF MUSCLE FATIGUE USING ACCELEROMETER, ELECTROMYOGRAPHY AND MUSCLE THICKNESS DATA
調査の概要
詳細な説明
Muscle fatigue is commonly assessed using surface electromyography (sEMG), particularly through frequency-domain parameters such as median frequency. However, fatigue-related changes are not limited to electrical activity and may also involve alterations in muscle mechanical behavior and morphological characteristics. Accelerometer-derived signals provide information regarding muscle vibrations and mechanical oscillations, while ultrasonographic measurements of muscle thickness provide information about muscle morphology and force-generating capacity.
The purpose of this study was to examine the relationships among muscle thickness, sEMG median frequency, accelerometer-derived mechanical vibration parameters, and isometric force variables during maximal voluntary isometric contractions performed at different knee flexion angles. Healthy male soccer players participated in a laboratory-based assessment protocol including ultrasonography, synchronized sEMG recordings, triaxial accelerometry, and isokinetic dynamometry.
Muscle thickness of the vastus lateralis obliquus (VLO), vastus medialis obliquus (VMO), and rectus femoris obliquus (RFO) muscles was measured using ultrasonography. Participants subsequently performed maximal voluntary isometric contractions at 90°, 60°, and 30° knee flexion angles. Surface electromyography, accelerometer signals, and force-related variables were recorded simultaneously. Median frequency values, acceleration-based root mean square (RMS) parameters, peak torque, mean torque, and time-to-peak torque variables were analyzed.
The study aimed to provide a multidimensional framework for muscle fatigue assessment by integrating morphological, electrical, and mechanical indicators and to explore their associations in healthy athletic populations.

Healthy Male Soccer Players
Healthy male soccer players aged 18-30 years who participated in a cross-sectional observational study.
Participants underwent ultrasonographic muscle thickness assessment, surface electromyography (sEMG), accelerometer-based mechanical vibration measurements, and isometric strength testing during maximal voluntary isometric contractions performed at different knee flexion angles (30°, 60°, and 90°).
|
Participants underwent non-invasive neuromuscular assessment procedures using surface electromyography (sEMG), triaxial accelerometers, ultrasonography, and an isokinetic dynamometer.
Measurements were performed during maximal voluntary isometric contractions at 30°, 60°, and 90° knee flexion angles.
The devices were used exclusively for data collection and assessment purposes.
No therapeutic, pharmacological, behavioral, or rehabilitative intervention was administered.
