Abstract: Objective:To verify the relationship between male university students' 1000m running and aerobic AC/CRF in the National Student Physical Health Standards (NSPHS) .Methods: 45 male university student volunteers were chosen to attend 公式 test directly in laboratory, and 1000 m time running , 3000 m time running, and 12 min running in track and field before receiving 公式test indirectly. Linear regression equation and multiple linear regression equation were applied to test the relationship between 1000m running and 公式; Random Forest Algorithm was used to compare the degree and ranking of three indirect test methods in reflecting 公式. Results:(1) As a one-way independent variable,1000m running can explain 39.7% of the total variation of 公式, and 29.9% of the total variation of 公式; (2) Multiple linear regression equations including the other independent variables in NSPHS can explain 47.6% of the total variation of公式, and 44% of the total variation of 公式. (3) Among the 3 test methods, indirect tests based on 12 min running and 3000 m running are more effective in evaluating the 公式 of male university students. Conclusion: The validity of 1000m running and related tests in NSPHS in evaluating the AC/CRF of male university students is not very effective. 12 min running and 3000m running can better measure the aerobic AC/CRF of male university students. It is recommended to use 12 min running or 3000m running for male university students' health promotion intervention in their physical education curriculum and extracurricular exercise. 12 min running or 2400m running are more accurate and convenient assessment methods.
