Abstract

OBJECTIVE

The purpose of this investigation was to develop a sub-maximal exercise test for estimating VO2max utilizing aerobic dance.

EXPERIMENTAL DESIGN

One hundred females between the ages 18 to 40 yr served as the subjects for test validation. The subjects completed a treadmill test to determine VO2max and were assessed for heart rate (HR) response to a bout of aerobic dance. The data associated with responses to treadmill exercise and the aerobic dance test, in conjunction with descriptive variables (e.g., age, BMI) were utilized in the validation of the multiple regression model.

MEASURES

Reliability was determined by correlation and paired "t"-tests of the aerobic dance routine test and retest trials. The construction of the multiple regression equation, via forward entry analysis, and the cross-validation of the regression equation were completed to ensure the validity and reliability of the protocol in accurately estimating VO2max.

RESULTS

Test, retest reliability for the dance-exercise routine was demonstrated (r = 0.98). Moreover, no significant differences were shown between the HR responses for the test and retest trials. The multiple regression analysis yielded a three variable multiple prediction equation for estimating VO2max (R = 0.84; SEE, 5.5 ml.kg-1.min-1). The three variables were the HR response to four min of aerobic dance (HR4), body mass index (BMI), and age (years). Cross-validation of the aerobic dance test was determined with a second group of 50 female subjects (R = 0.83; SEE, 5.5 ml.kg-1.min-1). Additionally, the application of the validation group regression equation to the cross-validation group yielded a comparable R of 0.82. Comparison of the predicted values for VO2max from both equations also yielded a highly significant invariance coefficient of 0.96. Finally, the results of "t"-tests between the observed and predicted mean values for VO2max revealed no significant difference (p > 0.05). Therefore, the final prediction equation, based on collapsing the means associated with the validation and cross validation samples (n = 150), was: VO2max (ml.kg-1.min-1) = 130.18-(0.38 * HR4)-(0.81 * BMI)-(0.27 * Age); R = 0.84, SEE = 5.5 ml.kg-1.min-1.

CONCLUSIONS

These results indicate that a four minute aerobic dance test provides a valid and reliable sub-maximal protocol for estimating VO2max and providing an index of aerobic fitness in apparently healthy 18 to 40 yr old females.

摘要

目的

本研究的目的是开发一种利用有氧舞蹈进行次最大运动测试以估算最大摄氧量（VO2max）的方法。

实验设计

100名年龄在18至40岁之间的女性作为测试验证的受试者。受试者完成了一次跑步机测试以确定最大摄氧量，并评估了她们对一段有氧舞蹈的心率（HR）反应。与跑步机运动和有氧舞蹈测试反应相关的数据，连同描述性变量（如年龄、体重指数）被用于多元回归模型的验证。

测量方法

通过对有氧舞蹈常规测试和重测试验进行相关性分析和配对“t”检验来确定可靠性。通过向前逐步回归分析构建多元回归方程，并完成回归方程的交叉验证，以确保该方案在准确估算最大摄氧量方面的有效性和可靠性。

结果

有氧舞蹈常规测试的重测可靠性得到了验证（r = 0.98）。此外，测试和重测试验的心率反应之间没有显著差异。多元回归分析得出了一个用于估算最大摄氧量的三变量多元预测方程（R = 0.84；标准误，5.5 ml·kg⁻¹·min⁻¹）。这三个变量是对四分钟有氧舞蹈的心率反应（HR4）、体重指数（BMI）和年龄（岁）。用另一组50名女性受试者对有氧舞蹈测试进行交叉验证（R = 0.83；标准误，5.5 ml·kg⁻¹·min⁻¹）。此外，将验证组回归方程应用于交叉验证组得到的R值为0.82。两个方程预测的最大摄氧量值的比较也得出了高度显著的不变系数0.96。最后，最大摄氧量的观察值和预测值之间的“t”检验结果显示无显著差异（p > 0.05）。因此，基于合并验证样本和交叉验证样本（n = 150）的均值得出的最终预测方程为：最大摄氧量（ml·kg⁻¹·min⁻¹）= 130.18 -（0.38×HR4）-（0.81×BMI）-（0.27×年龄）；R = 0.84，标准误 = 5.5 ml·kg⁻¹·min⁻¹。
