High intraocular pressure (IOP) is indicated as the main risk factor for the development of glaucoma. Studies have shown that both aerobic physical exercises and resistance training (RT) can promote significant reductions of IOP in individuals without the diagnosis of the disease. Objective: The objective of the present experimental study was to observe the association of lactate concentrations with intraocular pressure after two different RT protocols in individuals with Primary Angle Glaucoma (GPAA). Method: The study was carried out with 6 individuals with GPAA (2 men and 4 women) aged between 50 and 70 years. The volunteers were submitted to 2 sessions of resistance training consisting of: 3 sets of repetitions until the concentric failure to 60% of a maximum repetition (MRI) with 60s of recovery between the series (S1) and 3 sets of repetitions until the concentric failure to 80% of 1 RM (S2) with 120s of recovery between the series, carried out randomly and on different days, with at least one week between sessions. Nine exercises were performed in the following order: Leg press, Straight supine, Flexor chair, Frontal paddle, Leg presses twin, Adductor chair, Abductor chair, Abdominal machine and lateral elevation. The control group was composed of the same volunteers of the experimental tests, with the data obtained on different days of the training sessions. The lactate was collected in the same moments of measurement of IOP; immediately before the exercises, at the end of the fourth exercise, at the end of the training session, and five minutes after the end of the session. As statistical procedures, one way ANOVA was used with repeated measures to compare the variables according to the moments. The Bartlett test was used to analyze significant data indicated by ANOVA one way. The Tukey test, for the comparisons of the pairs of mean of the population studied. Results: IOP significantly reduced in the two protocols studied in relation to the control group, however, the S1 protocol, which promotes higher concentrations of lactate, has a higher potential reduction. Conclusion: RT protocols that promote greater participation of lactic anaerobic metabolism are more efficient in the reduction of IOP in glaucomatous individuals.
