Comparison of Cardiovascular Response between Men and Women to Isometric Exercise of Lower Limb

Hariraja Muthusamy, Salameh Aldajah, Sivanandan Ramar, Akram Omoush.

Background: Isometric exercise remains an important modality in patient’s rehabilitation and also employed in advanced strength and endurance training programs. The average isometric strength is generally about thirty percent greater in men than in women in different muscle groups, and that difference may reflect on the cardiovascular response to isometric exercise
Purpose: To study cardiovascular responses in men and women to isometric exercise.
Methods and Materials:
Thirty male subjects and thirty female subjects were randomly selected.. Isometric exercise to bilateral quadriceps muscles was performed for 2 minutes in supine position. Systolic blood pressure, Diastolic blood pressure and the Heart rate were taken for all the subjects by using Sphygmomanometer.
The post mean of DBP for male was 84.43 and for women was 80.47, it was statistically significant (‘t’ value = 2.27, df =58) at 0.05 level. So the DBP is significantly more among men than women. The post mean of SBP and for male was 125.47 and for women was 120.3, it was statistically significant (‘t’ value = 2.14, df = 58) at 0.05 level. So the SBP is significantly more among men than women. Conclusion:
Hence the results of this studies should be kept in mind while prescribing Cardiovascular patients with Isometric exercise since specific job tasks may require isometric or combined isometric and dynamic activities. This approach to cardiac rehabilitation may facilitate patients who wish to return to a job requiring frequent isometric muscle contraction.

Key words: Cardiovascular, Isometric exercise, Lower limb, men and women, blood pressure
