Skilled swimmers maintain performance stability under changing attentional focus constraints.

Focusing attention externally, rather than internally, has generally proved advantageous as it avoids interfering with self-organzing processes. However, some research has suggested that this may not necessarily be the case with highly skilled individuals who by definition possess a greater capacity to either adapt or maintain stability under varied task constraints. This study aimed to address this gap by comparing the performance of skilled athletes under internal and external attentional focus conditions using the swimming dive start as a task vehicle. Using a counterbalanced repeated measures design, skilled swimmers performed dive starts in conditions of differing attentional focus - internal and external attentional focus. Kinetic and kinematic variables were collected and statistical analyses conducted to compare differences between conditions. The results revealed no differences in outcome performance (relative peak power, horizontal velocity, and time to 5 m) between internal and external focus conditions. However, remaining kinematic and kinetic measures revealed that all movement events occurred earlier in the movement sequence, suggesting superior self-organization of movement in the external focus condition. An external focus may be beneficial for the organization of movement control in skilled swimmers, but may not have an immediate impact upon the outcome of the task.
