Physical performance is associated with visual acuity in university students: results of a school-based study

Abstract

SUMMARY 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.

“…Dear Editor, I was very glad to read the study by Wu et al 1 in which they demonstrated that physical exercise might help improve visual acuity and university students should practice strength exercises to improve physical performance. However, some concerns should be raised in my opinion.…”
