到目前为止,还没有研究研究咖啡因对模仿某些团队运动的长时间间歇性运动表现的影响,并且用于改善间歇性运动表现的咖啡因的合适浓度仍然难以捉摸。本交叉,双盲初步研究的目的是调查低,中,高剂量的咖啡因摄入对间歇性运动表现和认知的影响。10名男性进行了一次熟悉会议和四次实验性试验。受试者在运动前1 h服用安慰剂或咖啡因胶囊(3、6或9 mg/kg),安静休息,然后进行2 × 30 min的自行车运动。自行车运动方案包括每分钟最大功率蹬踏5 s(质量× 0.075 kp),中间为无负荷蹬踏25 s和休息30 s。在摄入胶囊前、摄入后1小时和运动后,参与者完成了Stroop任务。在Stroop任务中测量了平均功率输出(MPO)、峰值功率输出(PPO)和反应时间(RT)。只有3毫克/公斤的咖啡因有积极的影响,平均PPO和MPO; 3毫克/公斤的咖啡因显着降低RT在不一致和一致的条件。这些结果表明,在长时间间歇性运动和认知过程中,摄入低剂量咖啡因对参与者的体力有更大的积极影响,而不是中等或高剂量咖啡因。
To date, no study has examined the effects of caffeine on prolonged intermittent exercise performance that imitates certain team-sports, and the suitable concentration of caffeine for improved intermittent exercise performance remains elusive. The purpose of the present cross-over, double-blind preliminary study was to investigate effects of low, moderate, and high doses of caffeine ingestion on intermittent exercise performance and cognition. Ten males performed a familiarization session and four experimental trials. Participants ingested capsules of placebo or caffeine (3, 6, or 9 mg/kg) at 1 h before exercise, rested quietly, and then performed cycling for 2 × 30 min. The cycling protocol consisted of maximal power pedaling for 5 s (mass × 0.075 kp) every minute, separated by unloaded pedaling for 25 s and rest for 30 s. At pre-ingestion of capsules, 1 h post-ingestion, and post-exercise, participants completed the Stroop task. The mean power-output (MPO), peak power-output (PPO), and response time (RT) in the Stroop task were measured. Only 3 mg/kg of caffeine had positive effects on the mean PPO and MPO; 3 mg/kg caffeine decreased RTs significantly in the incongruent and congruent conditions. These results indicate that the ingestion of low-dose caffeine had greater positive effects on the participants’ physical strength during prolonged intermittent exercise and cognition than moderate- or high-dose caffeine.
