We explored machine learning strategies to model the relationship between the physiological time series, the participant’s anthropometric variables, and the binary outcome variable indicating whether the participant completed the test. All participants could complete the ten bouts at low or moderate-intensity work rates, however, when the bout work rates were high-intensity, 50% refused to begin the subsequent exercise bout before all ten bouts had been completed (task failure). This research examines the use of advanced machine learning methods to predict completion of a test consisting of multiple exercise bouts by a group of healthy children and adolescents. Additionally, until this work no methods have identified which dynamic gas exchange or heart rate responses influence an individual’s decision to start or stop physical activity. Nonetheless, the clinical use of exercise testing remains limited because interpretation of test results requires experience and specialized training. Physiological response to physical exercise through analysis of cardiopulmonary measurements has been shown to be predictive of a variety of diseases. ![]()
