Abstract
The purpose of the study was to determine the effect of 14 weeks of strength training with linear periodization (LP) and daily undulatory periodization (DUP) in performance by kinematics of the variables stroke rate (SR), stroke length (SL), speed average (SA) and stroke index (SI) in young swimmers of both sexes. Seventeen children (15.18 ± 2.31 years) were divided into two groups (G): GLP (4 males and 4 females) and GDUP (5 males and 4 females). For the results we conclude that DUP is more effective to provide improvements in the kinematic aspects of SA, SI, and shorter distances (up to 50 meters). LP is more efficient in maintaining muscle strength SL and SA variables at greater distances (over 50 meters).
