The present study examined the effects of an attentional intervention strategy on experienced, amateur athletes. The intervention was based on Brick, MacIntyre and Campbell’s (2014) new working model, devised for conceptual clarity. This study focused on one of these dimensions, the internal sensory monitoring strategy. The 10 sessions consisted of a 5000m row carried out on ergometers. A single-subject, multiple-baseline experimental design was utilised in order to assess the participant’s reaction to the intervention individually. Each participant’s time and average splits were recorded, an average heart rate (HR) was calculated and rate of perceived exertion (RPE) was noted at the end of each 5000m. There were no immediate improvements in performance, changes in HR varied across participants and no changes to RPE were noticed as a result of the intervention. Suggesting that, against the majority of literature, this associative condition does not have a superior impact on performance. Realistic applications of these findings are suggested as well as recommendations for future research.
