Changes in Neuromuscular, Perceptual and Cardiorespiratory Responses to Repeated Work-Matched High-Intensity Interval and Constant-Load Cycling Following Short Recovery Periods


We are conducting a research study examining how training load and short recovery periods influence fatigue during high-intensity cycling exercise. In a total of 8 visits, you will perform cycling while receiving muscle stimulations (non-invasive and painless) to measure your fatigue. The training sessions will involve both high-intensity interval training and continuous cycling.
