Effect intensity control of aerobic dance on cardiac function

Abstract

Cardiac function depends on resting heart rate, Blood pressure and efficiency of the lungs. And this is a best indicator of health. The purpose of this study was to find out the effect of Intensity control Aerobic Dance on Cardiac Function. To achieve the purpose, sixty (N=60, age 17±1.3, BMI 22± 2) school students were purposively selected from Jaffna, Sri Lanka, and divided into Group I (Aerobic Dance [(AD)( n=30, practice Aerobic Dance 30 to 60 min / day/ 2 to 3 day / week over the period of eight weeks)], Group II (n=30) Acted as control. The initial intensity was fixed at 60% and 5 % rule was applied to increase intensity in every two weeks. Subjects were measured Resting Heart Rate (RHR) using Palpating the radial artery for full one minute for each subject and blood pressure [Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP)] using Standardized sphygmomanometer and stethoscope. Before taking heart rate the subjects were asked to lie down in the carpet floor and relax. The resting heart rate and blood pressure were taken during early morning hours the collected data were statistically treated by using paired – samples ‘T’ test, 0.05 level of confidence was fixed to test the significance. The result shows that intensity controlled aerobic dance positively influence on RHR, SBP, and DBP than control group. Hence it was concluded that, any form of intensity controlled continues exercise may enhance cardiac functioning status in respect to RHR, SBP, and DBP. From the conclusion it was recommended that exercise in a submaximal work rate can leads to better cardiac function.
