Objective To analyze the trends on the quality of velocity and endurance among primary and secondary Hui students in Ningxia from 1985 to 2005,and to provide evidence for health promotion of students. Methods The data were collected from the Chinese national survey on students' constitution and health (1985,1991,1995,2000,2005,and 2010),and the grades of students' 50 m dash and endurance running were analyzed. Results From 1985 to 2010,50 m dash among boys decreased by 0.006 s meanwhile decreased by 0.24 s among girls.The score in 2005 was still higher than in 1985,but the score in 2010 was lower than in 1985;Endurance running decreased significantly.50 m×8 to and fro running among 7~12 year-old boys and girls decreased by 7.76 s and 6.68 s (P<0.01),1 000 m running among 13~18 year-old boys decreased by 16.38 s (P<0.01),and 800 m running among 13~18 year-old girls decreased by 15.45 s (P<0.01);From 1985 to 1991,students performed better in 50 m dash and endurance running.But the grade was on the decline from 1991 to 2010.The quality of velocity among urban students was better than rural students while the quality of endurance among rural students was better than urban students. Conclusions Over the past 25 years,the physical function and athletic ability of 7-18 year-old students in Ningxia Hui Autonomous Regions are still not optimistic.Comprehensive and effective measures should be taken to promote the status of students' physical health level.
