CONTINUOUS WAVEFORM ANALYSIS OF FORCE, VELOCITY, AND POWER ADAPTATIONS TO A PERIODIZED PLYOMETRIC TRAINING PROGRAM

This study assessed kinetic and temporal adaptations to the countermovement jump in response to a 6 week periodized plyometric training program. Twenty recreationally active women participated in this study (10 training and 10 control). Testing consisted of 3 maximal countermovement jumps on a force platform prior to and after six weeks of training. Analysis of characterizing phases (using a dependent t-test) was performed to assess differences between pre- and post-training sessions. Post-training force, velocity, and power were significantly different (p < 0.05). Periodized plyometric training altered the curves for force, velocity, and power. A combination of greater eccentric velocity and power followed by increased concentric power enhanced SSC and all three variables just before takeoff likely enhancing jump performance.
