• Resumen

  • This study investigated the effects of verbal motivation on isokinetic peak torque knee extension in children with two distinct personality types (introvert versus extrovert). The subjects were tested in three groups without verbal motivation, with verbal motivation from the tester, and with verbal motivation from the tester and the other participants. A 2 x 3 mixed ANOVA was significant for interaction (p < .001). Post-hoc testing for the introverted group revealed that scores without verbal motivation were significantly higher than with verbal motivation, and the extroverted group scores were higher with verbal motivation. T tests revealed that the extroverted group performed significantly better than the introverted group with verbal motivation (p < .05). Results suggest that verbal motivation has a varying effect on isokinetic torque generating capacity in children with different personality types
