Inter-Limb Asymmetry in Force Accuracy and Steadiness Changes after a 12-Week Strength Training Program in Young Healthy Men

The study aimed to investigate the impact of a 12-week strength training program on force accuracy and steadiness changes in lower limbs in young healthy men. Twenty subjects with a dominant right lower limb were included. They performed a force matching task both pre and post strength training prog...

Twenty subjects with a dominant right lower limb were included. They performed a force matching task both pre and post strength training program. The ability to reproduce force was determined by calculating three errors: absolute error (AE), constant error (CE), and variable error (VE). After intervention AE and VE improved in both legs indicating higher improvement in the dominant leg (<i>p</i> = 0.032 for AE and <i>p</i> = 0.005 for VE). However, CE improved only in the dominant leg (<i>p</i> = 0.001). We conclude that strength training improved the accuracy and consistency of force in a force reproduction task. This improvement was more evident in the dominant lower limb. Most likely, the inter-limb asymmetry in changes of force application ability caused by strength training is due to the different mechanisms responsible for the control of voluntary movements in the dominant and non-dominant lower limb.Rafał SzafraniecTadeusz StefaniakDariusz HarmacińskiMichał KuczyńskiMDPI AGarticleforce senseforce matching taskforce reproductionforce errorslower extremitiesresistance trainingMathematicsQA1-939ENSymmetry, Vol 13, Iss 2226, p 2226 (2021)
