BACKGROUND
Previous studies speculated that the Incremental Shuttle Walking Test (ISWT) is a maximal test in children and adolescents, however comparison between ISWT with cardiopulmonary exercise test has not yet performed. Furthermore, there is no regression equation available in the current literature to predict oxygen peak consumption (VO2 peak) in this population. This study aimed to assesses and correlate the cardiorespiratory responses of the ISWT with the cardiopulmonary exercise (CEPT) and to develop and validate a regression equation to predict VO2 peak in healthy sedentary adolescent boys.
METHODS
Forty-one participants were included in the study. In the first stage, the VO2 peak, respiratory exchange ratio (R peak), heart rate max (HR max) and percentage of predicted HR max (% predicted HR max) were evaluated in CEPT and ISWT (n = 26). Second, an equation was developed (n = 29) to predict VO2 peak. In both phases, the VO2 peak, respiratory exchange ratio R and hearth rate (HR) were evaluated. In the third stage, the validation equation was performed by another 12 participants.
RESULTS
Similar results in VO2 peak (P>0.05), R peak (P>0.05) and predicted maximum HR (P>0.05) were obtained between the ISWT and CEPT. Both tests showed moderate significant correlations of VO2 peak (r = 0.44, P = 0.002) e R peak (r = -0.53, P < 0.01), as well as the agreement of these measurements by Bland-Altman analysis (VO2 peak, bias = -0.13; R peak, bias = 0.0). Distance walked was the variable that explained 42.5% (R2 = 0.425, p = 0.0001) of the variance in VO2 peak. The equation was VO2 peak (predicted) = 20.94 + (0.02 x distance walked). The results obtained by the equation were not significantly different compared to the values obtained by the gas analyzer and the Bland-Altman analysis showed agreement (bias = 1.6).
CONCLUSION
The ISWT produced maximal cardiorespiratory responses comparable to the CEPT, and the developed equation showed viability for the prediction of VO2 peak in healthy sedentary adolescent boys.
背景
先前的研究推测递增 shuttle 步行测试（ISWT）是儿童和青少年的最大测试，但尚未对 ISWT 与心肺运动测试进行比较。此外，目前的文献中尚无可用的回归方程来预测该人群的最大摄氧量（VO2 峰值）。本研究旨在评估 ISWT 的心肺反应与心肺运动测试（CEPT）的相关性，并开发和验证预测健康久坐青少年男孩 VO2 峰值的回归方程。
方法
41 名参与者被纳入研究。在第一阶段，在 CEPT 和 ISWT 中评估了 26 名参与者的 VO2 峰值、呼吸交换比（R 峰值）、最大心率（HR max）和预测最大 HR 的百分比（%predicted HR max）。第二，开发了一个方程（n = 29）来预测 VO2 峰值。在两个阶段中，都评估了 VO2 峰值、呼吸交换比 R 和心率（HR）。在第三阶段，通过另外 12 名参与者验证了该方程。
结果
ISWT 和 CEPT 之间 VO2 峰值（P>0.05）、R 峰值（P>0.05）和预测最大 HR（P>0.05）的结果相似。两种测试均显示 VO2 峰值（r = 0.44，P = 0.002）和 R 峰值（r = -0.53，P <0.01）具有中度显著相关性，并且 Bland-Altman 分析也显示了这些测量值的一致性（VO2 峰值，偏差= -0.13；R 峰值，偏差= 0.0）。步行距离是解释 VO2 峰值方差的 42.5%（R2 = 0.425，p = 0.0001）的变量。方程为 VO2 峰值（预测）= 20.94 +（0.02 x 步行距离）。与气体分析仪获得的值相比，方程得到的结果没有显著差异，Bland-Altman 分析显示一致（偏差= 1.6）。
结论
ISWT 产生的最大心肺反应与 CEPT 相当，所开发的方程显示出预测健康久坐青少年男孩 VO2 峰值的可行性。
