During the half time of intermittent team sports, substantial physiological changes relating to acid–base balance and glycemic response affect the second-half performance. Refuel and rehydrate strategy is therefore necessary to be investigated. This field experiment assessed the acute effect of a brief mindfulness-based intervention (MBI) coupled with fluid intake on players’ cognitive function in a simulated soccer game. In a single-blinded, randomized, cross-over experiment, 14 male players received three treatments [Control: noncarbohydrate solution + traveling introduction audio; CHO: Carbohydrate (CHO)–electrolyte solution + traveling introduction audio; and CHO-M: CHO–electrolyte solution + MBI] during a simulated half-time break of a soccer game. Participants’ mindfulness level, blood glucose and lactate, rating of perceived exertion, and cognitive function performance assessed by the Stroop effect task (ST), Corsi block-tapping test (CBT), and rapid visual information processing task (RVIPT) were immediately measured before, during, and after the trial. Repeated measure ANOVA was used for statistical analysis. The results revealed that: (1) in ST, the CHO_M group performed better than the Control group and marginally better than the CHO group; (2) in CBT, both the Control group and CHO-M group responded faster in the posttest than in the pretest; however, the performance of the CHO group remained the same; (3) the CHO group spent less time on missing numbers in post RVIPT compared with the other two groups. In conclusion, findings of this study provided a preliminary evidence of the positive effect of MBI coupled with CHO intake on athletes’ cognitive function, with both positive and negative effect of CHO ingestion.

Key words: Mindfulness, soccer, carbohydrate, team sport

           Key Points
  • This is the first field research to examine the effect of a brief Mindfulness-based intervention during a simulated soccer half-time break on players’ cognitive function performance.
  • Findings provided a preliminary evidence of the positive effect of brief Mindfulness-based intervention coupled with Carbohydrate–electrolyte ingestion on participants’ cognitive performance.
  • Both positive and negative effects on athlete’s cognitive function were found for Carbohydrate ingestion.
