Effects of Traditional and Reverse Periodization on Strength, Body-Composition and Swim Performance.

The primary purpose of this research was to compare changes in 100m swim performance (t100c), Muscular Strength and Body-composition values after 14 weeks of training traditional periodization (control) and reverse periodization (treatment). There were 26 volunteer swimmers (16.02±0.6 yrs. 1.72±9.3 cm 64.1±9.3 kg) divided in two groups traditional periodization (TP) and reverse periodization (RP). Results at the 14th week showed significant improvements (p<0.05) in values of t100c (6.9%), Body-weigh (Bweigh 1.8%) and Maximal drag charge (MDC 10.0%) by RP above TP values. Moreover, TP exhibited substantial improvements in body composition decreasing significantly (p<0.05) fat mass. The results demonstrated that reverse periodization is specific and an efficient strategy of training for sprinters at time to economize load volume; traditional periodization is recommended option for improving physical appearance.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articleopen accessEntrenamiento deportivoDeporteInvestigación
