At Louisiana State University, undergraduate students are gaining firsthand research experience by using Noraxon technology to study one of the most important topics in human performance: fatigue.
Led by Dr. Xavier Thompson, Assistant Professor of Sports Science in the School of Kinesiology, students are participating in an ongoing research project examining how individuals respond to fatiguing exercise.
A Multi-System Approach to Understanding Fatigue
In the lab, students use Noraxon Ultium EMG sensors placed on the quadriceps muscles while participants perform testing on a CSMI Humac Norm Isokinetic Dynamometer. This setup allows students to examine how muscles behave as fatigue develops during controlled strength assessments
The project also incorporates:
- Near-Infrared Spectroscopy (NIRS) to assess muscle oxygenation
- Subjective ratings of perceived effort
By combining these tools, students can evaluate how muscle activation, oxygen availability, and force output change under different exercise conditions.
Hands-On Learning Through Research
Beyond collecting data, students are actively involved in the full research process. They gain experience with:
- EMG sensor placement and preparation
- Multi-device synchronization
- Live data collection and testing procedures
- Interpreting physiological and performance signals
- Understanding how setup decisions influence outcomes
These experiences help students appreciate that research quality often depends on attention to detail.
Preparing Students for Future Careers
Experiences like this help prepare students for careers such as:
- Physicians
- Allied health professionals
- Researchers
By combining technical skill development with critical thinking, students gain practical experience that extends beyond the classroom.
Learning by Doing
At LSU, undergraduate students are not waiting until graduate school to engage in meaningful research. They are building valuable skills now through applied projects that connect biomechanics, physiology, and performance science.
