Resistance training exercises acutely reduce intraocular pressure in physically active men and women.
Our purpose was to examine the effect of the chest press and leg press exercises on intraocular pressure (IOP) in physically active, college-aged students. Fifteen healthy males and 15 females performed 3 sets of 10 repetitions of the chest press or leg press with 70% 1 repetition maximum (1RM). IOP was measured using applanation tonometry with a Tono-PenXL prior to exercise, following each set and 5 minutes after the third set. Data were analyzed with a repeated-measures two-way analysis of variance and paired t-tests when necessary. A p < 0.05 was accepted as statistically significant. For the chest press, IOP was reduced 8.0% after the first set, up to 14.5% after the second and third sets, and remained depressed 5 minutes post exercise. For the leg press, IOP was reduced 6.9% after the second set and 13.2% after the third set. IOP began to return to the pre-exercise value during 5 minutes post exercise. Males and females had similar IOP responses to the chest press and leg press exercise. Dynamic resistance exercises induce modest postexercise decreases in IOP.
