Abstract

BACKGROUND

Cardiorespiratory fitness is a well-established independent predictor of cardiovascular health. However, the relevance of alternative exercise and non-exercise tests for cardiorespiratory fitness assessment in large cohorts has not been studied in detail. We aimed to evaluate the YMCA-step test and the Veterans Specific Activity Questionnaire (VSAQ) for the estimation of cardiorespiratory fitness in the general population.

METHODS

One hundred and five subjects answered the VSAQ, performed the YMCA-step test and a maximal cardiopulmonary exercise test (CPX) and gave BORG ratings for both exercise tests (BORGSTEP, BORGCPX). Correlations of peak oxygen uptake on a treadmill (VO2_PEAK) with VSAQ, BORGSTEP, one-minute, post-exercise heartbeat count, and peak oxygen uptake during the step test (VO2_STEP) were determined. Moreover, the incremental values of the questionnaire and the step test in addition to other fitness-related parameters were evaluated using block-wise hierarchical regression analysis.

RESULTS

Eighty-six subjects completed the step test according to the protocol. For completers, correlations of VO2_PEAK with the age- and gender-adjusted VSAQ, heartbeat count and VO2_STEP were 0.67, 0.63 and 0.49, respectively. However, using hierarchical regression analysis, age, gender and body mass index already explained 68.8% of the variance of VO2_PEAK, while the additional benefit of VSAQ was rather low (3.4%). The inclusion of BORGSTEP, heartbeat count and VO2_STEP increased R(2) by a further 2.2%, 3.3% and 5.6%, respectively, yielding a total R(2) of 83.3%.

CONCLUSIONS

Neither VSAQ nor the YMCA-step test contributes sufficiently to the assessment of cardiorespiratory fitness in population-based studies.

摘要

背景

心肺适能是心血管健康公认的独立预测指标。然而，在大型队列中，用于心肺适能评估的其他运动和非运动测试的相关性尚未得到详细研究。我们旨在评估基督教青年会台阶试验和退伍军人特定活动问卷（VSAQ）在一般人群中对心肺适能的评估作用。

方法

105名受试者回答了VSAQ问卷，进行了基督教青年会台阶试验和最大心肺运动试验（CPX），并对两项运动试验给出了BORG评分（BORGSTEP、BORGCPX）。确定了跑步机上的峰值摄氧量（VO2_PEAK）与VSAQ、BORGSTEP、运动后一分钟心跳计数以及台阶试验中的峰值摄氧量（VO2_STEP）之间的相关性。此外，使用逐步分层回归分析评估了问卷和台阶试验除其他与体能相关参数之外的增加值。

结果

86名受试者按照方案完成了台阶试验。对于完成试验者，VO2_PEAK与年龄和性别调整后的VSAQ、心跳计数和VO2_STEP的相关性分别为0.67、0.63和0.49。然而，使用分层回归分析，年龄、性别和体重指数已经解释了VO2_PEAK方差的68.8%，而VSAQ的额外贡献相当低（3.4%）。纳入BORGSTEP、心跳计数和VO2_STEP分别使R(2)进一步增加了2.2%、3.3%和5.6%，总R(2)为83.3%。
