The aim of this study was to examine the effects of a notational analysis-based intervention on coaches' verbal behaviour considering their physiological activation during competition and game actions. Verbal behaviour, physiological activation (heart rate), and game actions of 4 handball coaches were recorded for a total of 28 matches. Each coach was recorded in 7 matches, three pre-interventions, two post-intervention, and two retention. Verbal behaviour was assessed using the Coach Analysis and Intervention System (CAIS: Cushion et al., 2012), and game actions were coded as positive or negative depending on their outcome. In total, 15223 verbal behaviours and 3780 game actions were recorded. The intervention programme sought to help coaches to provide constructive information (corrective feedback and instructions) after negative events or actions, encourage players (especially when the team is losing or playing badly), reduce the protests to the referee, and reduce or eliminate punishment to players. Chi-square analysis suggested that the intervention stimulated the intended changes in coaches' behaviour, and that these changes were retained for subsequent games. Verbal behaviour changed depending on the physiological activation. This study suggests that a brief (two-session) notation-based intervention can elicit changes in coaches' verbal behaviour during competition.
