Peak heart rate estimation
FOX
Peak HR measured during each participant’s baseline cardiopulmonary exercise test dictated exercise intensity for that individual’s exercise prescription throughout the 12-week intervention. Data collection for this trial started in Fall 2019. After March 2020, due to COVID-19 research restrictions, we were unable to complete two baseline (and five EOS) cardiopulmonary exercise tests. For these cases, peak HR was estimated utilizing the age-predicted maximum HR equation developed by Fox and colleagues [
