Affect of Different Intensities of Queens College Step Tests on Cardiopulmonary Function and Body Composition in Students

Abstract

Objective: 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.
Method: 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 FEV?. 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.
Improvements: 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.
