Scheinowitz's lab main research interest focuses on the understanding of the physiological changes associated with exercise testing and training (conditioning/ adaptation) as well as factors that can improve exercise performance and delay fatigue. The main research topics studied are detailed below:
Thermal changes during high intensity exercise
We use thermal infrared (IR) camera to detect temperature changes before, during and after high-intensity short-term exercise, for further investigating the thermogenic aspect of muscle energetics. Also, this study will shed light on fundamental physiological and hemodynamic changes associated with high-intensity exercise.
Developing and evaluating prediction models in complex exercise settings.
Anaerobic capacity is an important measure for athletes. It is measured during short, high-intensity exercise testing such as the Wingate test. Since during aerobic exercise stress test, the anaerobic component significantly contributes to the performance toward the end of the aerobic exercise test, we are interested in extracting the anaerobic mechanical power outputs components (mean and peak power outputs) from the aerobic exercise stress test variables. This will generate aerobic and anaerobic mechanical power output data from a single exercise stress test, which will be highly useful under various sports activities.
The physiological and biomechanical aspects of cycling during standing position.
Cycling is a popular exercise that integrates amateurs and professionals of all ages. Elite cyclists, compared with amateurs one, spend cycling sessions in a standing position, particularly during high-intensity training and competitions. We are studying the physiological and biomechanical aspects associated with standing position specifically on how to improve physiological and/or biomechanical efficiency. The outcome of our study may have a huge impact on the world of cycling by determining the optimal position that generates the highest power output.
Fatigue and performance
Exercise performance is a key element in athletic activities and sports. In our lab we use EMG (electromyogram), a known clinical and scientific method, to monitor the electro-mechanical properties of skeletal muscles during exercise.. We use EMG to monitor and predict overtraining syndrome in athletes. We hope to establish the basis for better understanding of the electro-mechanical / neuromuscular pathways during exercise and fatigue....
The inter relationship between mental and physiological performance
We hypothesize that physical activity, training, and fitness level are independently and collectively, factors that may buffer the detrimental effects of psychosocial stress. Mental resilience may therefore buffer detrimental effects of acute physical stress on performance. We investigate the cross-interaction between physical response to an acute psychosocial stressor and the psychosocial response to acute physical stress among well-trained endurance athletes.
