Excessive training combined with inadequate recovery time could potentially result in overtraining syndrome (OTS), which is characterized by underperformance and fatigue. There are several methods in assessing overtraining though most if not all of them are retrospective.
In our lab we are interested in assessing acute fatigue as well as chronic condition of over-training, though, prospectively, while the situation emerges. For this purpose, we are measuring the electromechanical properties of skeletal muscles using electromyograph (EMG) electrodes during progressive exercise. In addition, we are looking at multi-variables that can contribute to over-training such as sleeping time and quality (as a measure of recovery), laboratory exercise performance (as a goal for the determination of training intensity), field training data (as a measure of the difference between training intensity goal to that actually performed), as part of a newly developed prediction models and algorithm.
Lastly, we are investigating the role of gut microbiome families of bacteria as potentially contributing to performance enhancement and delaying fatigue via buffering mechanism of lactic acid which is generated during high intensity, prolonged exercise by the working muscles.
The presentation will cover the research performed by our graduate students toward better understanding this complex phenomenon of fatigue and over-training in athletes.
