The purpose of this study is to evaluate the effects of Queens's college step test on cardiorespiratory endurance and body composition during aerobic exercise, and to find out the difference when the interval is modified.
Amongst thirty apparently healthy college students, fifteen were randomly assigned to a group (QCST) performing a normal Queens College step test and another fifteen were randomly assigned to a group (mQCST) performing a Queens college test with modified interval. The experiment was conducted three times a week for four weeks. Findings: Both groups showed positive enhancement in overall cardiorespiratory function and body composition after the experiment. In the QCST group compared to mQCST, there was an increment of 3.90% in FEV1. In the mQCST group compared to QCST group, there was a superior improvement of 1.01% in skeletal muscle mass and 2.41% in body fat percentage.
A short-term experiment was conducted in randomly assigned groups that did not achieve uniform matching where confounding bias cannot be excluded. Future findings for long-term experiments may include further positive outcomes of cardiorespiratory endurance and body composition changes in the mQCST group.
