Objective: To study and compare the effect of graded Isotonic exercise on Ocular Perfusion Pressure (OPP) in obese young adults.
Method: 100 healthy young adult volunteers comprising 50 obese and 50 non-obese of either gender in the age group of 18-21 years were selected among MBBS Phase I students of JSS Medical college, Mysuru. Isotonic exercise was performed using a treadmill of both mild and moderate grade under Bruce protocol. IOP and BP were recorded before and after performing exercise using standard methods. Mean arterial pressure (MAP) and OPP were calculated. Statistical analysis was done using paired t test to test the difference between the groups.
Results: OPP increased by 5.62±0.3 mm Hg after mild isotonic exercise in obese (3.13±0.16 in non-obese) and by 9.75±0.02 mm Hg after moderate isotonic exercise in obese (10.91±1.29 in non-obese). The changes were statistically significant (P< 0.001).
Conclusion: There was a significant increase in OPP after performing both grades of Isotonic exercises in obese individuals. Moderate intensity Isotonic exercise proves to be beneficial for ocular health as well as systemic health as it improves ocular perfusion.
