ObjectivesOur study had two objectives. First, we examined the relationship between dispositional sport-specific mindfulness and rowing performance. Second, we investigated whether dispositional sport-specific mindfulness moderated the moderating effect of conscious processing on the anxiety-performance relationship. DesignCross-sectional field study. Participants took part in a competitive race and completed a survey after the race. MethodRowers (N = 270) completed post-race measures of mindfulness, rowing specific reinvestment, perceived performance, anxiety and demographics. We also determined actual rowing performance. ResultsMindful refocus was positively associated with perceived and actual performance, whilst non-judgemental thinking was only positively associated with perceived performance. Rowing specific Conscious Motor Processing (RS-CMP) moderation effect on the anxiety-performance relationship was attenuated by high levels mindful awareness, this was true for both actual and perceived performance. Rowing specific movement self-consciousness (RS-MSC) moderation effect on the anxiety-performance relationship was moderated by non-judgmental thinking but only for perceived performance. ConclusionOur findings provide initial support that dispositional mindfulness may benefit performance under pressure and that this may be through the attenuation of reinvestment processes. Furthermore, the result demonstrated that mindful awareness and non-judgmental thinking may act on distinct reinvestment processes.
