Research Area Neurophysiology of Exercise

Research into movement variability and into the coordinative structure of movement patterns has gained momentum in recent years as the significance of these aspects of human movement for important functional characteristics, such as motor learning, balance and stability, situation adaptability, or coping with pathologies become more and more apparent.

Our research group investigates sensorimotor integration. We analyze movement variability; the coordinative structure of movement patterns (PCA; “principal movements”); how muscles are activated and how muscle activation is coordinated between muscles (EMG, muscle synergies); and we monitor brain activity (EEG) to link phenomena in the EEG with aspects of movement control.

One focus of our group is postural control research. The ability to accurately control one’s movements and posture is relevant in all stages of life. It’s one of the first things an infant learns and it determines to a large extend health, independence, and quality of life in old age. In sports, balance is highly relevant for performance and for injury prevention. It seems obvious that postural control is related to the coordination of the movements of different segments, however, how exactly does this coordinative structure manifest itself? Is better balance associated with faster, stronger, or better coordinated reaction to perturbations? What exactly changes in the movement characteristics during balance training? Do movement patterns differ between stable and unstable or between young and old subjects? How does fatigue affect balance and coordination? - Our group develops and applies methods examining covariation in segment kinematics to approach questions about balance and coordination from a new angle.

A second research focus is technique analysis in sports. The technique of an athlete is the specific coordinative whole-body movement pattern that the athletes exhibit in standard situations of their sport. On the one hand, the technique of an athlete depends on highly specific factors such as the specific body shape, motor learning history, and abilities of the individual athlete; on the other hand, there are common features in the techniques of athletes that allow an experienced coach to characterize, evaluate, and even suggest improvements to the specific techniques of athletes. Scientifically it is challenging how the techniques of different athletes can objectively be compared and how suggestions for improvements can be derived. We quantify the underlying coordinative structure of movements to quantify and compare the techniques between groups of athletes.

The goal of our neuromuscular system is to either produce or restrict movement. Think of kicking a soccer ball (produce movement) or trying to stand as still as possible on one leg (restrict movement). Either way, we can use 3D motion analysis to record and reconstruct the three-dimensional movements of all body segments during a certain task and find out how successfully the neuromuscular system controlled this movement task. An example could be to measure the body sway during a standing balance task or two record the ankle, knee, and hip joint angles while walking on a treadmill. Our research team uses two different technologies to carry out 3D motion analyses: Vicon and Xsens. During these activities, we might also be interested in how this neuromuscular control is maintained. Related to this, we can measure muscle activity using Electromyography (EMG) or the electrical activity in the brain using Electroencephalography (EEG).

Kinematic Principal Component Analysis (PCA)

One of our more focused research areas is the application of principal component analysis to 3D movement data in order to structure the movement into individual movement components that can be further analyzed. To find out more about the PCA and how to use it, check out the free software developed in our group: The PManalyzer.

Also, check out the video tutorials and explanations related to the application of PCA on movement data.
