Acute effect of trataka on heart rate between university level male and female students: A comparative study
Champak Bhadra, Dr. Kallol Chatterjee
The term yoga is derived from the Sanskrit word ‘yuj’ meaning to unite; the union of the individual self with the supreme self. According to the classical definition by Patanjali, yoga means controlling the modifications of mind. The hatha yoga cleansing processes have been placed into six groups of purification practices known as shatkarmas, the six shatkarmas are neti, dhouti, nauli, basti, kapalbhati, and tratak, trataka is intense gazing of a point developing concentration and cleansing the mind. Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval of the ECG wave. For the present study total 08 university levels students (04 male groups and another 04 female groups) were purposively selected from Dept. of Physical Education, Vinaya-Bhavana, Visva-Bharati University, Santiniketan, Bolpur, West Bengal, India. Their age ranges from 18-22 years. The study was conducted during the year 2017-20118 academic sessions in the institute laboratory. To measured heart rate of the heart, ECG test was used for the study. There were also the experts who helped to conduct the test. Before recording the parameter, the subject was asked to relax physically and mentally for few minutes. ECG was recorded by an ECG machine (BPL 108T-DIGI Single Channel, 12 leads ECG Machine) using standard chest and limb leads and heart rate was calculate from R wave to R wave interval of II lead of ECG graph. Each ECG graph was reported by trained physician. For the collection of data pre and post test was taken. The selected subject underwent an acute effect of 15 minutes trataka programmed at evening sessions, under the instruction and supervision of the supervisor and with the help of others experts. ANCOVA was applied to calculate the collected data at 0.05 level of significance and to identify the significance differences on experimental groups the mean critical difference was used as a post- hoc test. Presently the study clearly shoes that the table value was greater than calculated value ( Tab- F 0.05 = 6.61 > calculated value 1.658) So it was concluded that there was no significant difference on heart rate variability between University level male and female students by the acute effect of trataka practice. But the trataka practice was more affected on heart rate of the female students.
