目的：健康ABC长距离走廊步行（LDCW）旨在通过包括热身和超过400米的计时表现来扩展老年人自定节奏步行测试的测试范围。这项研究比较了LDCW和6分钟步行的表现，以确定LDCW是否鼓励更大的参与者努力。设计：受试者在单次访问中进行LDCW和6分钟步行。测试顺序在受试者之间交替，测试之间有15分钟的休息时间。地点：巴尔的摩退伍军人事务医疗中心。参与者：20名志愿者，年龄70 - 78岁。测量：LDCW包括2分钟的热身步行，然后是400米步行和6分钟的步行测试，在一个畅通的走廊上进行20米长的课程。静息时、散步前后分别记录心率（HR）和血压（BP）。结果：所有20名受试者的400米步行速度均高于6分钟，其中平均步行距离为402米。通过配对t检验，400米步行比6分钟步行的步行速度更快（平均差值= 0.23 m/sec, P < 0.001），结束FIR（平均差值= 7.6 bpm, P < 0.001）和收缩压（平均差值= 8.3 mmHg, P = 0.024）。结果与测试顺序和受试者健康水平无关。结论：提供热身步行和使用目标距离而不是时间鼓励受试者更接近他们的最大能力。这种低成本替代跑步机测试的方法可用于研究和临床环境，以评估健康状况并帮助识别老年人早期功能衰退。
OBJECTIVES: The Health ABC Long Distance Corridor Walk (LDCW) was designed to extend the testing range of self-paced walking tests of fitness for older adults by including a warm-up and timing performance over 400 meters. This study compares performance on the LDCW and 6-minute walk to determine whether the LDCW encourages greater participant effort.DESIGN: Subjects were administered the LDCW and 6-minute walk during a single visit. Test order alternated between subjects, and a 15-minute rest was given between tests,SETTING: The Baltimore Veterans Affairs Medical Center.PARTICIPANTS: Twenty volunteers age 70 to 78.MEASUREMENTS: The LDCW, consisting of a 2-minute warm-up walk followed by a 400-meter walk and a 6-minute walk test were administered using a 20-meter long course in an unobstructed hallway. Heart rate (HR) and blood pressure (BP) were recorded at rest and before and after all walks. RESULTS: All 20 subjects walked a faster pace over 400 meters than for 6 minutes, in which the mean distance covered was 402 meters. From paired t-tests, walking speed was faster (mean difference = 0.23 m/sec; P < .001), and ending FIR (mean difference = 7.6 bpm; P < .001) and systolic BP (mean difference = 8.3 mmHg; P = .024) were greater for the 400-meter walk than for the 6-minute walk. Results were independent of test order and subject fitness level.CONCLUSIONS: Providing a warm-up walk and using a target distance instead of time encouraged subjects to work closer to their maximum capacity. This low-cost alternative to treadmill testing can be used in research and clinical settings to assess fitness and help identify early functional decline in older adults.
