The Purpose of the Study Was to Find Out the Effects of Callisthenic Training on Selected Physical and Physiological Variables Among Engineering Students With Postural Deformities. to Achieve the Purpose of the Study, Fifty Engineering Students With Postural Deformities Were Selected Randomly from Anna University, Chennai. the Subjects Aged from 18 To22 Years. the Selected Subjects Were Divided into Two Equal Groups Namely Experimental and Control Groups of 25 Subjects Each. the Training Period Was Limited to Eight Weeks and For Six Days Per Week. the Callisthenic Training Was Selected As Independent Variables and Vo2max, Resting Pulse Rate, Flexibility and Balance Were Selected As Dependent Variable and It Was Measured By Vo2max, Cardio Radial Pulse, Sit and Reach, and Stroke Stand. All the Subjects Were Tested Two Days Before and Immediately After the Experimental Period on the Selected Dependent Variables. the Obtained Data from the Experimental Group and Control Group Before and After the Experimental Period Were Statistically Analyzed With Dependent‘T’-Test to Find Out Significant Improvements. the Level of Significance Was Fixed at 0.05 Level Confidences For All the Cases. Significant Improvement Was Found on Vo2max, Resting Pulse Rate, Flexibility and Balance of Experimental Group Due to the Effect of Callisthenic Training When Compared to the Control Group.
