The effects of three and five second maximal isometric contractions on upper body postactivation potentiation

Christopher A Rice, University of Texas at El Paso

Abstract

Postactivation potentiation (PAP) has been shown to occur in both the upper and lower body when one or multiple sets of a resistance exercises are executed at a high intensity before an explosive movement of similar nature. Purpose. To examine PAP in the upper body using three and five second isometric contractions. Methods. Strength and power trained males (n=20) with a minimum three years of training experience completed two testing sessions. All subjects completed three sets of three and five second maximal, isometric bench press contractions over the course of the testing sessions. Three sets of single, explosive push-ups separated by 90 seconds were completed before and after the isometric bench press contractions. Pre- and post-isometric force data were analyzed using a one way ANOVA. Results. Statistical analysis revealed no significant changes in peak force, or rate of force development. Conclusion. The results of the current investigation suggest that isometric contractions of three and five seconds do not produce PAP. ^
