- Influence of type of movement termination and sport practice on muscle activity during elbow extension movements Raúl Reina Vaíllo Francisco J. Moreno Hernánde Vicente Luis del Campo Rafael Sabido Solana Multidisciplinarias (Ciencias Sociales) karate volleyball elbow joint impact movement Electromyography Twenty participants were tested on rapid elbow extension movements.This experiment examined the effects of the type of termination(pointing vs. impact movements) and sport practice (karatevs. volleyball) on temporary specific electromyographic (EMG) andkinematic measures during elbow extension movements. EMG wasrecorded from triceps (main agonist) and biceps (main antagonist).The analysis of variance on the type of movement showed differenceson the time from onset of EMG activation to peak EMG inagonist and antagonist when these variables are normalized to aproportion of total movement time. Also, correlation analysis showedstrong correlations between the kinematic variables and thetime from onset of EMG antagonist to peak EMG. This variable is theonly EMG variable that presented differences in the analysis betweensport groups. The results allow us to conclude that the delay inthe biceps action expressed in the time from onset EMG activationto peak EMG normalized to a proportion of total movement time isan indicator of the performance level in fast movements. 2008 artículo científico 1885-3137 https://www.redalyc.org/articulo.oa?id=71041206 en http://www.redalyc.org/revista.oa?id=710 RICYDE.
