High-intensity aerobic exercise significantly reduced intraocular pressure in healthy young male adults.
This study sought to determine how aerobic exercise at various intensities affects intraocular pressure (IOP) in young adults.A repeated measures design was adopted. A group of 20 volunteers (mean age: 21.24±1.73 y) took part in this study. IOP was measured with a tonometer (iCare TA01i, Icare Finland, Finland). Subjects completed 4 cycle ergometer sessions. During the first session, power was increased by 60 W every 3 minutes until exhaustion, corresponding to peak power. For the 3 following tests, each lasting 25 minutes, subjects exercised at intensities of 50%, 70%, and 85% of peak power, respectively, and measurements were taken every 5 minutes.
