Abstract: | In this study, a self-modelling video intervention was delivered to four elite youth soccer players over 13 weeks of the competitive soccer season. A multiple-baseline, repeated measures single-subject design was used to explore the impact of the intervention on subcomponents of soccer performance and psychological variables, including self-efficacy and positive/negative affect. Statistical analysis indicated that there were significant changes between pre- and post-intervention scores for two players (1 & 3) on three subcomponents of performance (turns, headers and tackles). The findings of this study highlight the potential benefits of designing individualised pre-match video interventions with elite youth athletes.Lay Summary: Video self-modelling (VSM) is a behavioural intervention in which an athlete views a video of themselves engaged in adaptive behaviour, in order to learn to reproduce it effectively under pressure. In this study, the impact of a self-modelling video intervention is examined within a youth football soccer environment. |
