The application of the Shuttle Walking Test (SWT) to assess cardiorespiratory fitness and the intensity of this test in healthy participants has rarely been studied. This study aimed to assess and correlate the cardiorespiratory responses of the SWT with the cardiopulmonary exercise testing (CEPT) and to develop a regression equation for the prediction of peak oxygen uptake (VO2 peak) in healthy sedentary adult men.
In the first stage of this study, 12 participants underwent the SWT and the CEPT on a treadmill. In the second stage, 53 participants underwent the SWT twice. In both phases, the VO2 peak, respiratory exchange ratio (R), and heart rate (HR) were evaluated.
Similar results in VO2 peak (P>0.05), R peak (P>0.05) and predicted maximum HR (P>0.05) were obtained between the SWT and CEPT. Both tests showed strong and significant correlations of VO2 peak (r = 0.704, P = 0.01) and R peak (r = 0.737, P<0.01), as well as the agreement of these measurements by Bland-Altman analysis. Body mass index and gait speed were the variables that explained 40.6% (R2 = 0.406, P = 0.001) of the variance in VO2 peak. The results obtained by the equation were compared with the values obtained by the gas analyzer and no significant difference between them (P>0.05) was found.
The SWT produced maximal cardiorespiratory responses comparable to the CEPT, and the developed equation showed viability for the prediction of VO2 peak in healthy sedentary men.
穿梭行走试验(SWT)在评估心肺适能及其在健康参与者中的测试强度方面的应用鲜有研究。本研究旨在评估SWT的心肺反应并与心肺运动试验(CEPT)进行相关性分析,同时建立一个回归方程以预测健康久坐成年男性的最大摄氧量(VO₂峰值)。
在本研究的第一阶段,12名参与者在跑步机上进行了SWT和CEPT。在第二阶段,53名参与者进行了两次SWT。在两个阶段中,均对VO₂峰值、呼吸交换率(R)和心率(HR)进行了评估。
SWT和CEPT在VO₂峰值(P>0.05)、R峰值(P>0.05)和预测最大心率(P>0.05)方面获得了相似的结果。两项测试均显示VO₂峰值(r = 0.704,P = 0.01)和R峰值(r = 0.737,P<0.01)之间存在强且显著的相关性,并且通过Bland-Altman分析表明这些测量结果具有一致性。体重指数和步速是解释VO₂峰值方差40.6%(R² = 0.406,P = 0.001)的变量。将该方程得到的结果与气体分析仪得到的值进行比较,未发现两者之间存在显著差异(P>0.05)。
SWT产生的最大心肺反应与CEPT相当,并且所建立的方程在预测健康久坐男性的VO₂峰值方面显示出可行性。
