Participants Sixty-eight subjects (mean age 30.6☙.7 years range 18–52 years) with a wide range of ages and abilities Setting Human Performance Laboratory, University College Chester The subject continued stepping until he/she reached 80% of their maximum predicted heart rate, or reported a rating of perceived exertion of 15 (hard) on the Borg scale, or reached the end of the 10-minutes 5-stage test. The initial step rate was 15 steps per minute and every 2 minutes the tempo increased by 5 steps per minute. During the submaximal step test, subjects were asked to step on to and off a 30-cm step at a rate set by the metronome beat on an audio cassette. Following this, on separate days, subjects then completed the Chester step test (CST) on two occasions (CST1 and CST2). This study investigates the reliability and validity of the Chester step test, a submaximal test for the prediction of aerobic capacity, when compared to maximal oxygen uptake (V̇O 2Max) measured during a treadmill test.ĭesign Participants completed a V̇O 2Max Treadmill Test using a standardised fast incremental ramp protocol designed to elicit exhaustion in 8–12 minutes. Objectives The assessment of cardiorespiratory fitness is becoming more commonplace in both community and occupational health settings.
