Abstract

This study determined if the generalized equations created for the Rockport Fitness Walking Test were a valid estimation of cardiorespiratory fitness for adults with mental retardation (MR). Subjects included 25 males and females (mean age = 33.3 +/- 7.4 yr) with MR. A maximal treadmill test was administered (mean VO2peak = 29.5 +/- 7.2 ml.kg-1 x min-1; 2.2 +/- 0.62 l.min-1). Subjects' age, weight, sex, walk time, and immediate post-HR were used in the generalized equations for predicting VO2peak (mean VO2peak = 36.5 +/- 7.6 ml.kg-1 x min-1 and 2.7 +/- 0.66 l.min-1). Significant correlations (P < 0.01) were obtained between the measured and predicted peak VO2 levels. However, significant and consistent differences were also observed between the measured and predicted VO2peak values (P < 0.02). Only 28% (l.min-1) and 36% (ml.kg-1 x min-1) of the subjects' measured VO2peak fell within the prespecified value of the predicted VO2peak, thus indicating that the prediction equations overestimated the VO2peak and cardiovascular fitness levels of adults with MR.

摘要

本研究旨在确定为罗克波特健身步行测试创建的通用方程是否能有效估计智力发育迟缓（MR）成年人的心肺适能。研究对象包括25名患有MR的男性和女性（平均年龄 = 33.3±7.4岁）。进行了一次最大跑步机测试（平均峰值摄氧量 = 29.5±7.2 ml·kg⁻¹·min⁻¹；2.2±0.62 l·min⁻¹）。将受试者的年龄、体重、性别、步行时间和运动后即刻心率用于预测峰值摄氧量的通用方程中（平均峰值摄氧量 = 36.5±7.6 ml·kg⁻¹·min⁻¹和2.7±0.66 l·min⁻¹）。实测和预测的峰值摄氧量水平之间存在显著相关性（P < 0.01）。然而，实测和预测的峰值摄氧量值之间也观察到显著且一致的差异（P < 0.02）。只有28%（l·min⁻¹）和36%（ml·kg⁻¹·min⁻¹）的受试者实测峰值摄氧量落在预测峰值摄氧量的预定值范围内，这表明预测方程高估了患有MR的成年人的峰值摄氧量和心血管适能水平。
