A Description and Comparison of Cardiorespiratory Fitness Measures in Relation to Pitching Performance Among Professional Baseball Pitchers.

Unlabelled: The purpose of this study is to provide descriptive and comparative information regarding the cardiorespiratory fitness of professional baseball pitchers. Twenty-four ( = 24) major league (ML) baseball pitchers (starters = 14; relievers = 10) over seven seasons (2007⁻2013) were evaluated. A modified Bruce protocol and the CardioCoach™ CO₂ metabolic analyzer were used to estimate VO and anaerobic threshold (AT) at the beginning of each season.
