The study assessed the general endurance status of 08 male athletes aged 16 – 18 years of the Jujitsu youth team of Dong Nai City with more than 02 years of training seniority. Through the synthesis of monographs and interviews with 15 experts and expert coaches, the project sets up a combination of measurement tools including 06 biological function indicators and 05 pedagogical tests to assess general endurance. Pre-experimental data showed that the endurance capacity of the sample system was relatively uniform with a low coefficient of variation in most test standards. However, when compared with the scientific works of domestic and foreign authors, the basic aerobic capacity and cardiovascular response function of the young male athlete Dong Nai currently stand at the low average threshold, not approaching the load norm of modern competition trends.
