Acute Effects of PNF Stretching on Maximum Voluntary Contraction in Men

Abstract

This study aimed to investigate the influence of PNF stretching on the peak torque (PT) isokineticleg extension PT at 600° and 180°s-1 in the stretched and unstretched limbs. Twelve college male athletes who wereenrolled in a fitness class volunteered to participate in the study. Pre and post PNF stretching exercises isokineticPT for extension and flexion of the dominant and non-dominant limbs were measured. There was a decrease in thePT for both extension and flexion between the pre- and post-stretching conditions. The reductions in PTexperienced in the present study tentatively support the hypothesis that stretching may change the length-tensionassociation. © Kamla-Raj 2015.
