Cardiovascular Response to Exercise: Static v/s Dynamic.

ABSTRACT

Background: Limited research has been carried out to compare acute cardiovascular responses to static and dynamic exercise in older adult. So in our study we compared the responses to static and dynamic exercise in older adults to find out and support the inclusion of resistance exercise as a part of fitness program designed for healthy subjects of older age group. Aims & Objective: The purpose of this study was to compare the acute cardiovascular responses of healthy older adults to static and dynamic exercise. Methods: In the present study 8 healthy normotensive volunteers, recruited in age group of 40-60 years, performed IHG exercise. Their HR and BP were recorded prior to and after one minute of 40% maximum voluntary contraction of the forearm. Then after a gap of two weeks subjects, performed dynamic exercise using ergo metric cycle. Their HR and BP were recorded prior to and after one minute of completion of exercise. All the recordings were compared before and after both types of exercise. Results: Both types of exercise led to significant rise in SBP, & HR. The rise in DBP was significant in subjects who performed static exercise only. From BP and HR responses, it is clear that acute responses to both exercises are almost similar, supporting the inclusion of static exercise in exercise programs for older adults. Conclusion: This study indicates that the press or response is well regulated in both exercise groups. This supports the inclusion of resistance exercise as part of an overall fitness program designed for healthy older adults.
