To analyze the criterion-related validity and the reliability of fitness field tests for evaluating cardiorespiratory fitness in adults, by sex, age, and physical activity level.
Cross-sectional.
During 3 weeks, sociodemographic, anthropometric measurements, a treadmill maximal test, the 2-km walk test, and the 20-m SRT were performed in 410 adults aged 18-64 years. Measured and estimated VO (by Oja's and Leger's equations) were analyzed.
Measured VO was associated with estimated VO by the 2-km walk test and 20-m SRT (r = 0.784 and r = 0.875, respectively; both p < 0.01). Bland-Altman analysis showed a mean difference of -0.30 ml* kg * min (p < 0.001, d = -0.141) in the 2-km walk test, and 0.86 ml* kg * min (p = 0.051) in the 20-m SRT. Significant mean differences between test and retest were found in the time to complete the 2-km walk test (-1.48 ± 0.51 s, p = 0.004, d = -0.014) and in the final stage reached in the 20-m SRT (0.04 ± 0.01, p = 0.002, d = 0.015). Non-significant differences were found between test and retest in the estimated VO by Oja's (-0.29 ± 0.20 ml* kg * min, p > 0.05) and Leger's eqs. (0.03 ± 0.04 ml* kg * min, p > 0.05). Moreover, both test results and estimated VO equations showed a high test-retest reliability.
Both tests were valid and reliable for evaluating cardiorespiratory fitness in adults aged 18-64 years, regardless of sex, age, and physical activity level.
分析不同性别、年龄和身体活动水平的成年人心肺适能的现场测试的效标关联效度和可靠性。
横断面研究。
在 3 周内，对 410 名年龄在 18-64 岁的成年人进行了社会人口统计学、人体测量学测量、跑步机最大测试、2 公里步行测试和 20 米冲刺测试。分析了测量和估计的 VO（通过 Oja 和 Leger 方程）。
2 公里步行测试和 20 米冲刺测试的测量 VO 与估计 VO 相关（r 值分别为 0.784 和 0.875，均 p 值 < 0.01）。Bland-Altman 分析显示，在 2 公里步行测试中，平均差值为-0.30mlkgmin（p 值 < 0.001，d 值=-0.141），在 20 米冲刺测试中，差值为 0.86mlkgmin（p 值=0.051）。在完成 2 公里步行测试的时间（-1.48±0.51s，p 值=0.004，d 值=-0.014）和 20 米冲刺测试的最后阶段达到的速度（0.04±0.01，p 值=0.002，d 值=0.015）上，测试和重测之间存在显著的平均差异。在 Oja 方程（-0.29±0.20mlkg*min，p 值>0.05）和 Leger 方程（0.03±0.04mlkg*min，p 值>0.05）估计的 VO 方面，测试和重测之间没有发现差异。此外，两种测试结果和估计的 VO 方程都显示出较高的测试重测可靠性。
对于 18-64 岁成年人的心肺适能评估，两种测试都具有有效性和可靠性，无论性别、年龄和身体活动水平如何。
