EYE-FIT is a randomized clinical trial with a two-arm parallel design aimed at assessing the impact of performing a structured and supervised physical training program on the different variables associated with glaucoma progression in pharmacologically treated primary open angle glaucoma patients. This intervention will include a supervised 24-weeks concurrent (endurance + resistance) training program comparing its influence to the standard care.
There are claims that more physically active individuals are less likely to glaucoma onset and progression. However, to date, there is not a single randomized controlled clinical trial assessing the impact of performing a structured and supervised physical training program on glaucoma progression. A randomized controlled clinical trial with a two-arm parallel design will be used to determine the chronic effects of a 24-weeks concurrent (endurance + resistance) training program in comparison to a control group (no training prescribed) on the ocular function and physical fitness of primary open angle glaucoma patients. Participants will be randomly divided in one of the two groups (experimental or control [wait-list]), while ocular function and physical fitness will be assessed before and after the intervention by researchers blinded to the group allocation of each participant. In addition, primary open angle glaucoma patients will be subdivided according to their medical treatment in two groups (prostaglandin analogues and combination of prostaglandin analogue and beta-blockers). Therefore, four groups will be considered in this clinical trial. The results of the EYE-FIT clinical trial will provide novel information on the influence of exercise on different markers of glaucoma, and may help to reduce the clinical, economic and social burden of this disease.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| exercise | Experimental | The intervention (endurance + resistance training) group will perform 48 training sessions (24 weeks, twice per week). In each session, they will perform the leg and arm cycling exercises during the first half of the session (15 minutes of leg cycling and 15 minutes of arm cycling) and resistance training exercises involving the lower-body (e.g., squat) and upper-body (e.g., a variety exercises performed against the resistance imposed by elastic bands) during the second half of the session. |
|
| control | No Intervention | The control group will not perform any supervised training program, and will follow standard care. |
