Zusammenfassung: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 VO2max (by Oja's and Leger's equations) were analyzed. Measured VO2max was associated with estimated VO2max by the 2-km walk test and 20-m SRT (r = 0.784 and r = 0.875, respectively; both p  0.05). Moreover, both test results and estimated VO2max 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.
