Cardiovascular Responses to Isometric Handgrip Training in Normotensive Medical Students

ABSTRACT

Background: Dynamic handgrip exercise evaluates autonomicresponses to physical activity. The isometric hand gripexercises training effect on cardiovascular system so thatsimilar benefits if any could also be obtained to same extent insimilar age group if they practice physical training regularly.Though there is a vast knowledge on exercise, but data onexercise and its effects on the cardiovascular system and longterm survival are still limited.Material & Methods: A Randomized cross sectional studydone on 100 MBBS students from Mulayam Singh YadavMedical College Meerut. Subjects were evaluated before andafter the training sessions of isometric handgrip exercise forhemodynamic changes like blood pressure, Pulse rate andmaximum volumetric contraction.Results: In present study the mean value of SBP weresignificant but DBP non- significant (P=0.001, 0.005NSrespectively) in Male and Female (P=0.001, 0.005NSrespectively).Conclusion: Thus the arterial pressure reduction reported inthis study would have an important impact on thesecardiovascular related illnesses. Furthermore, our resultssupport the concept that isometric training is an effectivemodality in the prevention of hypertension.
