title: Vocal disinhibition (grunting) does not increase dead lift force in college athletes or nonathletes.
abstract: 31 17-35 yr.-old men (15 college athletes and 16 nonathletes) performed three dead-lifts with and three without grunting, the order of which was randomly assigned. No differences were found across the grunting trials and grunting did not affect maximal force production. Grunting does not appear to increase maximum force production significantly during a large muscle group, force output activity (isometric dead lift).
