Fitness Test

The Modified Canadian Aerobic Fitness Test (mCAFT) is a submaximal fitness test used to estimate aerobic capacity. Participants who were deemed eligible for the mCAFT using the Physical Activity Readiness Questionnaire (PAR-Q) completed the mCAFT once during the study. The mCAFT protocol required participants to complete one or more stages of three minutes of stepping until they reached their predetermined ceiling heart rate for their age. During each three minute stage the participant stepped up and down on two steps at a specific rate. At the end of the test the heart rate was measured for one minute.
