First established in the landmark 2009 study, brain endurance training (BET) has been shown in fMRI brain scans and numerous peer-reviewed studies to improve athletic performance by targeting the part of the brain responsible for managing fatigue, decision making and the suppression of undesirable impulses aka will power.
Research done in 2015 by Rewire’s scientific advisor, Walter Staiano showed that brain training is highly effective in improving endurance performance when combined with traditional physical training. Those in the brain-training group had a 3x improvement in time to exhaustion (TTE) than the control group (+126% compared to +42%) over a 12 week training period.
In order to measure your performance, the Rewire system records all of the traditional physiological metrics such as average heart rate, average and normalized power, intensity factor (IF), training stress score (TSS), cadence, interval time and total workout time. Additionally, the system also tracks your mental performance including response time, accuracy, RPE, session RPE, and a proprietary metric called your perception gap. Your Perception Gap is the difference between your self-rated RPE (how hard you think you worked) compared with your expected RPE based on how hard you actually worked under the conditions of mental fatigue, using data from the power meter and heart rate monitor. By measuring the difference between your perception vs. your actual physical performance the Rewire system establishes a methodology whereby you can measure your mental performance over time. The goal is to reduce the gap in your perception when training or competing under mentally fatiguing situations so that your mind is not a limiter to achieving your true athletic potential.
