Effect of Different Dance Training on Vital Capacity among Post-Pubescent Girls

Abstract

The pulmonary and circulatory system are responsible for sending blood to lungs and returned to the heart and getting rid of waste products in your blood while helping to distribute blood rich in oxygen. Dance training can help to strengthen and make this system more efficient. The aim of this study was to investigate the effect of different dance training on Forced Vital Capacity. To achieve the purpose ninety (N=90) women students (mean age 17 years) were randomly selected from, Jaffna, Sri Lanka as subjects and divided in to Aerobic Dance (AD), Bharathanatyam Dance (BD) and Kandyan Dance KD) groups. They practice their respective dance for 60±10min / day for 3 days / a week over the period of twelve weeks. Data were collected on Forced Vital Capacity (FVC) by PC based USB Spirometer before and after the intervention programme. Dependent `t' test was used to find out difference between pre and post test. After eliminating the influence of pre-test on post-test means of experimental groups the analysis of variance (ANOVA) was used to find out the mean gain differences. In addition to this, Scheffe's post-hoc test was employed (p=0.05). The results of the study reveal, aerobic (Percentage of Improvement (PI) 48.16), bharathanatyam (PI 37.56), kandyan (PI 32) dance training influenced the forced vital capacity. Further the result of post hoc test shows that there was a significant difference between Aerobic and Bharathanatyam (Mean Gain Difference (MGD) 0.28*), Aerobic and Kandyan dance (MGD 0.41*) groups on Forced Vital Capacity. However in Bharathanatyam dance and Kandyan dance (MGD 0.13) a insignificant difference was observed on vital capacity. From the result it was concluded that Aerobic, Bharathanatyam and Kandyan dance training positively influence on pulmonary function in respect of forced vital capacity.
