Their age ranged from 18 to 25 years. The selected participants were randomly divided into two groups such as group 'A' Bhastrika pranayama practices (n=10) and group 'B' acted as control group (n=10). Group 'A' underwent Bhastrika pranayama practices for alternative three days and each session lasted for an hour for six week. Control group was not exposed to any specific training but they were participated in regular activities. The "nostril clip method" (seconds) was used to measure breath holding time were selected as variables. The pre and post tests data were collected on selected criterion variables prior and immediately after the training program. The pre and post-test scores were statistically examined by the dependent 't' test and Analysis of co-variance (ANCOVA). The level of significant was fixed at 0.05 level. It was concluded that the breath holding time group had shown significantly improved in breath holding time. However the control group had not shown any significant improvement on breath holding time.
