The effects of a mental skills training package of gymnasium triathlon performance

The present study examined the effects of a mental skills training package on gymnasium triathlon performance (in the south of England, UK). Five male participants (mean age 24.2±4.56 years, range=20-32 years) took part in a single-subject multiple baseline across individuals design, which was used to evaluate an intervention package including goal setting, relaxation, imagery, and self-talk. The results of the study indicated the mental skills package to be effective in enhancing triathlon performance for all 5 participants. Additionally, all participants increased their usage of mental skills from baseline to intervention phases. Follow-up social validation checks indicated all participants to have perceived the intervention to be successful and enjoyable, and all were satisfied with the delivery and content of the package. The findings provide further evidence to suggest mental skills training packages to be effective for endurance performance.
