To analyze the status and trends of physical fitness test data among college freshmen with different body mass index (BMI) groups from 2014 to 2024, providing the scientific evidence for monitoring and intervening in college students' physical health.
A census was conducted on all 67 949 freshmen at Civil Aviation University of China from 2014 to 2024. Physical tests included vital capacity, sit-and-reach, sit-ups, 50 m sprint, standing long jump, pull-ups, and 800 m/1 000 m run. Freshmen were divided into underweight, normal weight, overweight and obese groups according to WHO BMI standards. The Kruskal-Wallis H test was used to compare differences in physical fitness indicators across gender and BMI groups, while the Mann-Kendall trend test was employed to detect upward or downward trends in physical indicators over time.
From 2014 to 2024, statistically significant differences were observed in vital capacity, 50 m sprint, standing long jump, and sit-and-reach among different BMI groups for both genders (boy: Z=2 396.40, 4 160.33, 4 662.23, 531.85; girl: Z=593.37, 308.86, 499.37, 128.70). Significant differences were also found in 1 000 m run and pull-ups for boys, and 800 m run and sit-ups for girls across BMI groups (boy: Z=6 574.80, 6 880.48; girl: Z=528.56, 146.18) (P < 0.01). Overall physical test scores showed a declining trend during 2014-2024, particularly pronounced in overweight and obese groups. Male vital capacity in 2014 exceeded national survey data(d=320 mL), with the gap widening to 734 mL by 2019, while the female vital capacity difference increased from 271 mL in 2014 to 576 mL in 2019. Male 1 000 m run times were 23.0 s and 17.5 s faster than national data in 2014 and 2019 respectively, while female 800 m run times were 22.3 s and 21.5 s faster than corresponding national data.
Physical health status among freshmen at this university varies across BMI groups and changes over time. Although overall test scores remain higher than national levels, the declining trend in physical fitness performance requires attention.
