Abstract:
The purpose of the present study was to find out the effect of Aerobics and Zumba on Vo2 max (Predicted) of 20 to 25 years old working women. Total 90 working women participated in the study, out of which 30 subjects were selected at random for the Aerobics group another 30 subjects were selected at random for the Zumba group and other 30 subjects were considered as the member of the control group. The subjects were selected from various non govt. and corporate sectors office of Salt Lake and Newtown area of Kolkata. Queen College test was applied to the subjects. Subject stepped up and down for total duration of Three minutes. Metronome was set at 88 bpm. After competition of 3 minute step up-up-down-down on the stepper at the rate of 22 steps/minutes, all the subjects were directed to stop and seat. Heart beats were counted from carotid artery for 15 second from 5 to 20 second recovery. Predicted Vo2 max was recorded in ml/kg/min. by using the following formula for women. Vo2max. = 65.81 – (0.1847 X step test pulse rate (bpm). [McArdle, Katch and Katch. 1972] Aerobics and Zumba training introduced for three alternative days in a week and for total duration of Twelve weeks. Pre-test and Post-test data were collected. Analysis of Covariance (ANCOVA) was conducted to identify the effect of Aerobics and Zumba on Vo2 max (predicted). Result indicates that there is significant difference between Aerobics and Zumba group because p –value is 0.000 which is less than 0.05 level of significance. As well as there is also significant difference between means of both Aerobics and Zumba with control group (p=0.000), in both the cases p- value is less than 0.05 level of significance. The study concluded that Vo2 max was improved significantly after twelve weeks Aerobics and Zumba treatment. Aerobics group was superior to Zumba group for improving Vo2 max.
