Objective:
The aim of our study is to explore the relationship between physical performance and visual acuity in university students in China.
Methods:
tests of standing long jump, 50-meter dash and pull-ups sit-ups were conducted. The visual acuity was measured using a logarithm of the minimum angle of resolution (logMAR) chart. Pearson correlation was used to test the correlation of physical performance with visual acuity in university students.
Results:
The number of pull-ups was negatively associated with visual acuity in the left eye for male students, while a negative correlation was found between the time of the 50-meter dash and visual acuity in the right eye for female students.
Conclusions:
Our study identified that physical exercise might help improve visual acuity. University students should practice strength exercises to improve physical performance.
