Effect of Linear and Non-Linear Periodized Resistance Training on Dynamic Postural Control and Functional Movement Screen

Abstract

Periodization is an important component of resistance training programs. It is meant to improve adherence to the training regimen, allow for constant progression, help in avoiding plateaus, and reduce occurrence and severity of injuries. The aim of this study was to investigate the effects of linear per iodized (LP) and nonlinear per iodized (NLP) resistance training on Dynamic Postural Control and Functional Movement Screen. This study was designed as a randomized controlled trial with pretest and post-test model. The subjects were randomly categorize into a control group (n=15) that underwent linear periodization and an intervention group (n=15) submitted to nonlinear periodization training. A 4-week exercise protocol was applied to both groups. The LP program followed a pattern of intensity and volume changes every week. After the trial, both groups presented significant gains in Dynamic Postural Control and Functional Movement Screen. The findings of the current study indicate greater improvement in Functional Movement Screen (p=0.001) and Y Balance Test (p=0.001) scores for the Nonlinear Periodization model. In conclusion, both LP and NLP are effective, but NLP may lead to greater gains in Dynamic Postural Control and Functional Movement Screen over a 4-week training period. However, more research is needed in this area, particularly among trained individuals and clinical populations. Future studies may benefit from using instruments that are more sensitive for detecting changes in outcome measures.
