title: Psychological, muscular and kinematic factors mediate performance under pressure.
abstract: It is well established that performance is influenced by pressure, but the underlying mechanisms of the pressure-performance relationship are poorly understood. To address this important issue, the current experiment evaluated psychological, physiological, and kinematic factors as mediators of the pressure-performance relationship. Psychological, physiological, and kinematic responses to three levels of competitive pressure were measured in 23 males and 35 females during a golf putting task. Pressure manipulations impaired putting performance. Self-reported anxiety, effort, and perceived pressure were increased. Heart rate, heart rate variability, muscle activity, and lateral clubhead acceleration were also elevated. Mediation analyses revealed that effort, muscle activity, and lateral acceleration partially mediated the decline in performance. Results confirmed that pressure elicits effects on performance through multiple pathways.
