The effects of age on response time, accuracy, and shoulder/arm kinematics during hammering.

Abstract The aim of this study was to investigate the effects of age on response time and accuracy during a hammering task. Older male workers aged 51–69 years (older group: OG, n = 23) and younger male reference individuals aged 25–36 years (younger group: YG, n = 16) performed the experiment. Response time, accuracy, and 3D shoulder/arm kinematics were acquired using motion capture. The effects of age were investigated using linear mixed model analysis. Response times were significantly longer for OG compared with YG (P
