Assessment of cardiovascular endurance in swimmers and nonswimmers by comparing resting blood pressure.

ABSTRACT

Background and Objective: Swimming is often recommended by various authoritative groups as a mode of exercise for the prevention and treatment of hypertension and cardiovascular disease. Hence the current study compares the cardiovascular functional abilities with respect to Blood pressure in young freestyle swimmers practicing regularly and non-swimmers. Materials and Methods: The present Study was carried out at tertiary health centre of Municipal Corporation of Greater Mumbai on medical students after the informed and written consent. Sixty male medical students of age group 18 – 25 years fulfilling the inclusion criteria were included. The study was carried out by forming 2 groups. One group was the study group, comprising of 30 students who are swimmers, practicing for at least 3 months regularly with one session of 30-60 minutes duration per day and minimum three days in a week were include in the study group. The control group comprised of 30 students who are non-swimmers. Their Blood pressure was measured using sphygmomanometer. The data was recorded and analysed for the statistical significance using student’s‘t’ test. P less than 0.05 were considered the level of significance. Result: The mean resting systolic blood pressure in swimmers is significantly lower than in non-swimmers and is statistically significant (p = 0.000). The mean resting diastolic blood pressure in swimmers is significantly lower than in non-swimmers and is statistically significant. (p = 0.000). Discussion and Conclusion: Finding ways to initiate and maintain a physically active lifestyle, particularly with older adults, is a challenge to the practitioner. Swimming has been recommended as an alternative to land-based activity, particularly for older individuals, those who are obese or those who have limited mobility. Our finding may have important implications for exercise prescription in Younger and Older subjects.
