A study conducted with the objective to test the effect of six weeks step aerobic training on selected kinetic (Ground Reaction Force) and Kinematic (Temporal) variables of female. The study was delimited to female subjects only (N=16), age ranging from 18 to 22 years, height of step platform set to 8 inches and intensity of training set to 118 beats per minute. The study delimited to selected kinetic (ground reaction force) variables namely as Peak Force in X-axis on Force Plate 2(PF2X), Peak Force in y-axis on Force Plate 2 (PF2Y), Peak Force in z-axis on Force Plate 2 (PF2Z), Peak Force in X-axis on Force plate 1(PF1X), Peak Force in Y-axis on Force Plate 1(PF1Y), Peak Force in Z-axis on Force Plate 1(PF1Z), Kinematic (Temporal Variables) namely as Time taken to achieve Peak Force in X-axis on Force Plate 2(TPF2X), Time taken to achieve Peak Force in Y-axis on Force Plate 2(TPF2Y), Time taken to achieve Peak Force in Z-axis on Force Plate 2(TPF2Z), Time taken to achieve Peak Force in X-axis on Force plate 1(TPF1X), Time taken to achieve Peak Force i in Y-axis on force plate 1(TPF1Y), Time taken to achieve peak force in Z- axis on force plate 1(TPF1Z). The Data Recording and quantification for pre test and post test were administered by Dynamometric Analysis (force plate recordings) was performed. Collected data were computed with mean, standard deviation and t-test. The variables namely as PF1Y, PF2Y, PF2Z, TPF2X, TPF2Y, TPF2Z and TPF1Y has significantly increased and variables TPF1X, PF1X, PF1Z, PF2X, TPF1Z decreased significantly. Six weeks of step aerobic training were found to be sufficient length of training (training cycle) for biomechanical adaptation. All the selected kinetic (ground reaction force) and kinematic(Temporal) variables supported each other as per the existing literature or research and were found suitable for step aerobic training evaluation.
