Introduction.  The purpose of this study was to investigate the effects of 6-week Plyometric training program on biochemical and physical fitness parameters. A group of 40 female volleyball players (mean ± SD: age 22.05 ± 1.67 years, height 1.67 ± 0.04m, body mass 58.62 ± 3.73 kg), who participated in inter-college volleyball competition and in the Catch Them Young (CTY) programme volunteered to participate. All participants were informed about the study aim and methodology as well as about the possibility of immediate acceptance at any time of the experimentation.  Subjects agreed to the above conditions in writing. They were randomly assigned into Plyometric (P) and control (C) groups, n=20 each. Written consent, approved by the Directorate of Sport, Guru Nanak Dev University, Amritsar, Punjab, India was obtained from each subject prior to data collection. Group (P) was subjected 6-week Plyometric training program 45 min a day and the control group did not perform any Plyometric training techniques. No Significant between-group differences were found in the Plyometric (P) group, in haemoglobin (t=0.0318), urea (t=1.422), uric acid (t=0.160), total cholesterol (t=1.406), triglyceride (t=1.422) and aerobic capacity (t=0.326) as the analysis of the performed examinations shows that the calculated value of t is less than tabulated value of (t=1.729) for the selected degree of freedom and level of significance whereas significant between-group differences were noted in body composition (t=2.465*) and abdominal strength & endurance   (t=.13.424*), since the calculated value of t is greater than tabulated value of t (t=1.729). No significant changes were found in the control groups.
