Effects of linear and diary undulating periodization on strength, power and speed in youngs handball team players

Abstract

The purpose of the present study was to compare if significant differences exist between two different models, linear periodization (LP) and daily undulating periodization (DUP), in eliciting gains in strength, power and speed in adolescent athletes. Twenty six male handball team players of two different teams, with the same competition level in the same club, were assigned to one and another periodization group. The participants were tested for 1-RM back squat and bench press, a countermovement jump (CMJ), a triple jump with both legs, a 20- meters speed test, a standing medicine ball throw, a 7-meters standing throw and a 9-meters jumping throw. Training protocols involves 6 sessions of hypertrophy, 6 of power strength and 4 of explosive strength. There were 2 sessions per week during 8 weeks. LP group performed sessions in this order and DUP group alternated every week two different sessions. Volume and intensity were equated for each training p rogram.
