Comparison of the physiological responses of the Incremental Shuttle Walk test and Glittre-ADL test: complementary instruments for the evaluation of functional capacity

ABSTRACT The aim of the study was to assess and compare the cardiovascular, ventilatory and metabolic responses of the Incremental Shuttle Walk test (ISWT) and Glittre Activities of Daily Living test (Glittre-ADL test). This is a cross-sectional study with individuals. The functional capacity (FC) was evaluated by distance and peak oxygen consumption (VO2peak) in the ISWT and time spent and VO2 in Glittre-ADL test. Thirty individuals went through 656.67 (CI95%:608.8-704.5) meters at the ISWT and performed the Glittre-ADL test in 2.4 (CI95%:2.2-2.6) minutes. The peak VO2 of the ISWT was 27.8 (CI95%.6-29.9) vs. 22.2 (CI95 .5-24.1) mL×kg−1×min−1 (p<0.001) in the steady state (SS) of the Glittre-ADL test. Correlations between distance traveled in the ISWT and the time spent in Glittre-ADL test, VO2 peak of ISWT and VO2 in SS of Glittre-ADL test and HR at the ISWT peak and at the Glittre-ADL test SS were moderate to high magnitude. The Glittre-ADL test has lower metabolic, cardiovascular and ventilatory responses compared to ISWT, despite correlations between variables.

摘要
本研究旨在评估并对比增量穿梭步行试验（Incremental Shuttle Walk test，ISWT）与Glittre日常生活活动能力试验（Glittre Activities of Daily Living test，Glittre-ADL test）的心血管、通气及代谢反应。本研究为针对个体的横断面研究。采用ISWT中的步行距离与峰值摄氧量（peak oxygen consumption，VO2peak）、Glittre-ADL试验中的耗时与摄氧量，对受试者的功能容量（functional capacity，FC）进行评估。
30名受试者在ISWT中完成的步行距离为656.67米（95%置信区间：608.8~704.5），并在2.4分钟（95%置信区间：2.2~2.6）内完成Glittre-ADL试验。ISWT的峰值摄氧量为27.8（95%置信区间：26.6~29.9）mL·kg⁻¹·min⁻¹，而Glittre-ADL试验稳态（steady state，SS）下的摄氧量为22.2（95%置信区间：21.5~24.1）mL·kg⁻¹·min⁻¹，组间差异具有统计学意义（p<0.001）。
ISWT步行距离与Glittre-ADL试验耗时、ISWT峰值摄氧量与Glittre-ADL试验稳态摄氧量、ISWT峰值心率（heart rate，HR）与Glittre-ADL试验稳态心率之间的相关性均为中至高程度。尽管各变量间存在相关性，但相较于ISWT，Glittre-ADL试验所引发的代谢、心血管及通气反应均更低。
