Introduction: Changes in echo cardio graphic standard measurements as a consequence of 8 weeks of conditioning 4 weeks of reconditioning and 6 weeks of reconditioning have not been comprehensively studied. Sample: Twenty four residential untrained male subjects (age between 22-24 years) were selected for the study. Methodology: Two-dimensional and  colour Doppler echocardiography studies were performed for measuring left ventricular end systolic volume (LVESV), left ventricular end Diastolic volume (LVEDV), Ejection Fraction (EF), Fractional shortening (FS), Stroke volume (SV) and resting heart rates (RHR) of the subjects. Four times the data were collected from the subjects i.e. before conditioning protocol, at the end of  eight weeks conditioning programme, at the end of four weeks of deconditioning and at the end of six weeks of reconditioning. Analysis of data: Repeated measured design was applied for the study and ‘t’ tests were applied for statistical purpose. The statistical analysis was tested for significance at 0.05 level of confidence. Findings and conclusions : All the parameters except LVESV were significantly changed following conditioning  protocol , only SV, FS, RHR were significantly differ in case of reconditioning  protocol and RHR and HRsub were significantly changed after conditioning,  reconditioning and reconditioning.
