背景/目标:本研究旨在调查三种解决方案的效果,即碳水化合物-电解质-溶液(CES),碳水化合物-电解质-蛋白质溶液(CEPS),和安慰剂(PLA),大学足球运动员的认知功能。
■16名男性大学足球运动员在一项随机交叉研究设计中完成了三项主要试验。在每次主要审判中,参与者完成90分钟Loughborough间歇穿梭试验(LIST)方案,并消耗三种溶液之一.进行认知功能测试;血糖和乳酸浓度,每个试验中还记录了一些主观测量结果.
■与运动前水平相比,快速视觉信息处理测试(RVIPT)的准确性和视觉搜索测试中的响应时间(VST,复杂级别)在CES和CEPS试验中LIST改进后,但在解放军审判中没有。然而,在CES和CEPS试验中,VST(复杂水平)的准确性都有所下降,与PLA试验相比。CEPS消耗提高了VST(简单级别)的准确性,与CES消费相比。在CEPS试验中血糖浓度维持良好,但在CES和PLA试验中没有。
■似乎CES和CEPS消费在香港男性大学足球运动员认知功能的某些方面都显示出一定的益处。然而,这些影响可能特定于所测试的认知领域。
Background/Objectives: The present study aimed to investigate the effects of three solutions, i.e. carbohydrate-electrolyte-solution (CES), carbohydrate-electrolyte-protein-solution (CEPS), and placebo (PLA), on cognitive function of college soccer players.
UNASSIGNED: Sixteen male college soccer players completed three main trials in a randomized cross-over study design. In each main trial, participants completed 90 min Loughborough Intermittent Shuttle Test (LIST) protocol and consumed one of three solutions. The cognitive function tests were performed; blood glucose and lactate concentrations, and several subjective measurements were also recorded in each trial.
UNASSIGNED: Compared with pre-exercise level, the accuracy of Rapid Visual Information Processing test (RVIPT) and the response time in Visual Search Test (VST, complex level) after LIST improved in CES and CEPS trials, but not in PLA trial. However, the accuracy of VST (complex level) decreased in both CES and CEPS trials, compared with PLA trial. CEPS consumption improved accuracy in VST (simple level), compared with CES consumption. Blood glucose concentrations were well maintained in CEPS trial, but not in CES and PLA trials.
UNASSIGNED: It seems that both CES and CEPS consumption show certain benefits on some aspects of cognitive function in male college soccer players in Hong Kong. However, these effects may be specific to the cognitive domain tested.
