Summary
Aerobic exercise temporarily increases choroidal thickness (CT) and volume (CV) in young adults. Recovery of CV after exercise is influenced by sex and physical activity levels.
Area of Science:
- Ophthalmology
- Exercise Physiology
- Human Physiology
Background:
- Choroidal thickness (CT) and volume (CV) are key indicators of ocular health.
- The impact of acute aerobic exercise on choroidal parameters in young adults is not fully understood.
Purpose of the Study:
- To evaluate changes in choroidal thickness (CT) and volume (CV) after aerobic physical exercise in healthy young adults.
- To investigate the relationship between physical activity levels and choroidal changes post-exercise.
Main Methods:
- Seventy-two healthy young adults (22-37 years) underwent ocular biometry and spectral-domain optical coherence tomography (SD-OCT) with Enhanced Depth Imaging.
- Measurements of CT and CV were taken at baseline and at 3 and 10 minutes post-10 minutes of dynamic physical exercise.
- International Physical Activity Questionnaire assessed participants' physical activity levels.
Main Results:
- Choroidal thickness (CT) increased in subfoveal, nasal, and superior areas at 3 minutes post-exercise.
- Between 3 and 10 minutes post-exercise, CT decreased in all areas, with some falling below baseline.
- Choroidal volume (CV) changes mirrored CT; recovery was linked to sex and physical activity level.
Conclusions:
- Higher habitual physical activity correlates with greater resting CV.
- Healthy young adults exhibit dynamic adjustments in CT and CV during and after aerobic exercise.
- Women and more active individuals showed greater reduction in total CV during recovery.

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
