Key result
The 2-km walk and 20-m shuttle run tests strongly correlate with measured VO2max in adults.
Why the study?
The study was conducted to analyze the criterion-related validity and reliability of fitness field tests for evaluating cardiorespiratory fitness in adults, across sex, age, and physical activity level.

Are the 2-km walk test and 20-m shuttle run test valid and reliable for evaluating cardiorespiratory fitness in adults?
The 2-km walk test and 20-m shuttle run test are valid and reliable field tests for assessing cardiorespiratory fitness in adults.
Supports field CRF test validity in adults; leaves open prognostic integration pending longitudinal outcome data.
OBJECTIVES: 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. DESIGN: Cross-sectional. METHODS: (by Oja's and Leger's equations) were analyzed. RESULTS: equations showed a high test-retest reliability. CONCLUSIONS: Both tests were valid and reliable for evaluating cardiorespiratory fitness in adults aged 18-64 years, regardless of sex, age, and physical activity level.

Marín‐Jiménez et al. (2023) conducted a cross-sectional in Healthy adults (evaluating cardiorespiratory fitness) (n=410). 2-km walk test and 20-m shuttle run test vs. Treadmill maximal test (measured VO2max) was evaluated on Correlation between measured VO2max and estimated VO2max (r = 0.784 (2-km walk) and r = 0.875 (20-m SRT), p=<0.01). The 2-km walk test and the 20-m shuttle run test demonstrated high criterion-related validity (r = 0.784 and r = 0.875, respectively) and reliability for evaluating cardiorespiratory fitness in adults.
