Multimodal Fatigue Profiling in Collegiate Male Runners

Yekai Wang's study integrates cardiopulmonary, neuromuscular, and biomechanical data from 20 healthy collegiate male athletes performing high-intensity treadmill exercise. The dataset includes gas exchange, heart rate, perceived exertion, sEMG metrics from four leg muscles, and plantar kinetic measures from in-shoe sensors. It provides a structured framework for analyzing fatigue-related adaptations beyond metabolic indicators.

Use Cases

• Analyze correlations between sEMG metrics (iEMG, RMS, MF) and post-exercise plantar kinetic variables like contact area and vertical ground reaction force.
• Model side-specific load redistribution by comparing left-foot and right-foot vertical ground reaction force data before and after exercise.
• Investigate the relationship between cardiopulmonary variables (gas exchange, heart rate) and neuromuscular fatigue indicators from rectus femoris and biceps femoris sEMG.
• Assess changes in midfoot contact area and mean pressure from plantar kinetics as potential mechanical markers of acute fatigue.

Strengths

• Integrates three distinct data modalities: cardiopulmonary exercise testing, surface electromyography, and plantar kinetic assessment.
• Includes sEMG data from four specific leg muscles: rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius lateralis.
• Reports statistically significant changes in plantar kinetics, including a 12.3% increase in midfoot contact area.

Limitations

• Small sample size of 20 participants limits statistical power and generalizability.
• Dataset is restricted to a specific demographic of healthy collegiate male athletes.
• Correlations between neuromuscular and plantar kinetic measures did not remain significant after false discovery rate correction.
