Background: This field experiment investigated the acute effects of brief mindfulness-based intervention (MBI) coupled with carbohydrate (CHO) intake on players’ recovery from half-time break in a simulated soccer competition. Methods: In a single-blinded randomized crossover experiment, 14 male players received 3 treatments (Control: non-carbohydrate solution + travelling introduction audio; CHO: CHO–electrolyte solution + travelling introduction audio; and CHO_M: CHO–electrolyte solution + MBI) during simulated half-time breaks. Vertical jump, sprint performance, mindfulness level, rate of perceived exertion, muscle pain, mental fatigue, blood glucose, and lactate were measured immediately before, during, and after the exercise. Results: (1) MBI significantly increased participants’ mindfulness level (Control vs. CHO_M, p < 0.01; CHO vs. CHO_M, p < 0.01) and decreased mental fatigue for CHO_M condition (pre vs. post, p < 0.01); (2) participants in the CHO_M condition performed better in the repeated sprint tests than in the Control and CHO condition (Control vs. CHO_M, p = 0.02; CHO vs. CHO_M, p = 0.02). Conclusion: Findings of this study provide preliminary evidence of the positive effect of MBI coupled with CHO ingestion on athletes’ recovery from fatigue in the early stage of the second half of a game.

短暂正念干预结合碳水化合物摄入对恢复足球运动员活力的急性影响：随机交叉试验

背景：这项现场实验研究了在模拟足球比赛中，短暂的正念干预 (MBI) 与碳水化合物 (CHO) 摄入相结合对球员中场休息恢复的急性影响。方法：在单盲随机交叉实验中，14 名男性玩家接受 3 种治疗（对照：非碳水化合物溶液 + 旅行介绍音频；CHO：CHO – 电解质溶液 + 旅行介绍音频；CHO_M：CHO – 电解质溶液 + MBI）在模拟的中场休息期间。在运动前、运动中和运动后立即测量垂直跳跃、冲刺表现、正念水平、感知用力率、肌肉疼痛、精神疲劳、血糖和乳酸。结果：（1）MBI 显着提高了参与者的正念水平（对照组与 CHO_M，p < 0.01；CHO 与 CHO_M，p < 0.01），并减少了 CHO_M 条件下的精神疲劳（前与后，p < 0.01）；(2) CHO_M 条件下的参与者在重复冲刺测试中的表现优于对照和 CHO 条件下的参与者（对照与 CHO_M，p = 0.02；CHO 与 CHO_M，p = 0.02）。结论：本研究结果提供了初步证据，证明MBI联合CHO摄入对运动员下半场比赛初期疲劳恢复具有积极作用。
