Association between the focus of attention and brain activation pattern during golf putting task in amateur and novice: A fNIRS study.

PURPOSE

External focus of attention (FOA) has been shown to improve motor performance. However, recent research has found that the effectiveness of FOA is related to the level of expertise. Therefore, this study examined the effects of FOA on putting performance in golfers of different levels of expertise. The neural mechanisms behind FOA were explored in conjunction with fNIRS.

METHOD

A total of 30 participants, including 15 amateurs (M: 23.31(SD = 1.32)years; 15 males) and 15 novices (M: 22.69(SD = 1.55) years; 11 males; 4 females) were recruited. Participants completed EF and IF golf putting at a duration of 3s per time wearing fNIRS for 3 blocks of 30 s interspersed with 10-s rest blocks.

RESULT

Behavioral results showed a significant difference in the putting performance of the amateur group under the EF condition compared to the IF condition (P = 0.019), and relative to novices, the amateur group performed better under the EF condition (P = 0.003). fNIRS results revealed that the amateur group had higher activation levels in the right somatosensory association cortex (RSAC) and right motor cortex (RMC) under the IF condition. In contrast, for the novice group, higher activation levels were observed in the left prefrontal cortex and RMC under the EF condition.

CONCLUSIONS

Our results revealed SAC and MC over-activation in the amateur group under IF conditions with poor golf putting performance. Our findings suggest that the impairment of automated motor neural networks could be a possible mechanism by which IF affects motor performance with SAC and MC over-activation. Guiding novices to focus on task-related factors consciously could be a potential mechanism by which EF enhances motor performance.
