Influence of Handgrip Exercise on Intraocular Pressure
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 2
Abstract
Purpose: The aim of this study is to investigate the effect of handgrip exercise on intraocular pressure (IOP) in young healthy adult males in Tamilnadu population. Background: Several studies support the fact that lifestyle modification like exercise has capacity to lower the intraocular pressure and this effect can be used in the management of glaucoma or ocular hypertension along with medication. Most of the previous studies targeted on effect of whole body Isotonic exerciseon IOP. This study was initiated to assess the effect of isometric exercise on IOP, a simple measure to postpone the development of glaucoma and its complications. Methods: In this quasi experimental study, 44 young healthy adult male subjects of age 18 to 25years were selected, who fulfilled the inclusion and exclusion criteria. Baseline IOP was measured in both eyes using noncontact tonometer. The subjects were instructed to hold Smedley’s handgrip dynamometer with 20% of maximum voluntary contraction in a sustained manner for the period of minimum 2minutes or until fatigue sets in (Isometric exercise). IOP was measured immediately after the isometric exercise. IOP variation was analysed using paired t test. Result: A small but significant decrease in IOP noted immediately after handgrip (isometric) exercise in both eyes with average fall in right eye of 1.70mm of Hg and in left eye of 1.65mm of Hg. Conclusions: This study showed that IOP significantly decreased in both eyes after the Isometric exercise using hand grip dynamometer in healthy adult males which can be extrapolated and clinically applied to treat glaucoma patients and its prevention.
