BACKGROUND: The purpose of this study was to investigate the effect of undulating periodized plyometric training on power, sprint, and agility performance. Forty-eight amateur male soccer and futsal players volunteered.
METHODS: The pretest included the measurement of squat jump height, countermovement jump height, the Wingate anaerobic test, 20 m sprint test, and Illinois agility test. After the pretest, the subjects were randomly assigned into four groups: a) traditional periodization, b) daily undulating periodization, c) weekly undulating periodization, and d) control. The training program consisted of six weeks, three sessions per week. The volume load of the training programs was matched among groups.
RESULTS: Significant improvement was shown with all periodization models in jumping height, Wingate peak power, sprint, and agility performance. Wingate average power was significantly increased with traditional and weekly undulating periodization. There was no significant difference among the periodization models of plyometric training in Wingate average power. The peak and average power from the jump significantly increased with daily undulating and weekly undulating periodization compared to the control group. Furthermore, daily undulating periodization had a significant increase compared to traditional periodization in jumping peak and average power. In addition, no periodization model had significant effects on minimal power and fatigue index.
CONCLUSIONS: Except for the jumping power, there were no significant differences among the periodization models of plyometric training in the measured variables. Total volume load of plyometric training is more important than the variation of training volume and intensity in order to gain explosive functions.
