The average of three blood pressure readings using an Omron M3 blood pressure monitor and an Omron cuff (32–42 cm) while at rest at one-minute intervals was used.
CRF, an index of metabolic and cardiovascular profile, was assessed using the 3 min Step Test [24 (link)] which has been found to strongly correlate with VO2max and have excellent discriminative validity in a pediatric population [25 (link)]. Participants step up and down on a 30.5 cm step at an established rhythm set of 24 steps per minute using a digital metronome KORG Micrometro. Heart rates (HR) are monitored prior to the test, during the 3 min of exercise load (step-test), immediately after, and one minute post [24 (link)] using the electronic analyzer, TM 100 Pro Tech Med Heart Rate Monitor. Post-effort HR values were analyzed and recorded for one minute. Scores were automatically generated based on the arithmetic mean of HR following Jacks et al. formula [26 (link)] to categorize CRF as very poor, poor, satisfactory, good, very good, or excellent.
