The Study analyzes the difference in the cardiovascular response to isometric upper limb exercises between healthy young males and females.
The study was conducted on young volunteers, 15 males and 15 females, of mean age 20±1 years to study the gender variation in cardiovascular response to isometric exercises. The baseline cardiovascular parameters (HR, SBP, DBP, MAP and RPP) were measured before the exercise. After two sets of three static upper limb exercises for 3 minutes, the parameters were recorded at the end of the exercise and 3 minutes into recovery. An increase in HR, SBP and RPP was seen in both the groups after exercise. This increase was more pronounced in males (p<0.05) than females. DBP and MAP decreased in both the groups, but females showed a greater fall. The RPP showed a significant increase (p<0.05) in males as compared to females. This indicates that the males have higher myocardial oxygen demand during isometric exercise, predisposing them to greater risk of ischemia, if they develop any cardiovascular risk factor compromising the coronary blood flow.
