The purpose of this study was to find out the effects of asana and core training on breath holding time, vo2 max and resting pulse rate level of middle aged working women. The sample consisting of sixty middle aged women ranging between 35-50 years. They were divided into two groups, consisting control group and experimental group. The control group was not given any treatment and the experimental group was given asana and core training programme was given five days per week for a period of 8 weeks. All the subjects were subjected for pre and post test. Physiological variables of breath holding time, vo2 max and resting pulse rate level. The data collected from the subjects were statistically analyzed with ‘t’ ratio to find out significant difference among experimental group and control group and physiological variables if any. The result indicates that eight weeks of asana and core training programme produced significant improvement in breath holding time, vo2 max and resting heart rate level.
