摘要

机译:<![cdata [ 背景: 我们检查了摄取了两种预科补充剂(PWSS)对选择性关注和反应抑制的影响,感知运动准备(本文,准备)和锻炼性能相关的参数。 方法: 耐受培训的参与者( n ?=Δ19)被随机分为双盲,交叉(7天洗涤)安慰剂(PLA) - 控制补充(1)PLA的研究; (2)PWS [β-丙氨酸(3.2 ~g),精氨酸α酮戊酸(2.0 ~g),硝酸酯(2.0 ~g),抗坏血酸(500×mg), n - 乙酰酪氨酸(300μmg),咖啡因(300μmg),四甲基硫酸(10×mg), mucuna pruriens 标准化为15%l-dopa(1.0〜g),冬季(10?mg) ,吡哆醛5-磷酸(1.48×mg),叶酸(0.50≤mg)和甲基丙氨酸(1.8〜mg)]; (3)PWS150 AT?150%PWS剂量。主要结果是用于一致性,不一致和干扰任务的Troop测试响应。二次结果是准备和运动性能(板凳和腿部按压/卧室)。通过一般线性模型分析数据,并作为平均值(标准偏差)或平均变化[95%置信区间,CI]。 结果: 对于PWS(6.57,95%CI [1.36-11.8])和PWS150(11.5,95%CI [6.26-16.6 ]),但不是PLA(1.31,95%CI [3.89至6.52])。对于PWS150,观察到速率变化的显着变化(8.1,95%CI [4.52-11.6])和PLA(4.47,95%CI [0.89-8.05]),但不是PWS(2.31,95%CI [?1.26至5.89])。观察到类似的结果。当所有结构域都求和时,PWS150(27.42计数,95%CI [16.08-38.76])和PWS(12.26计数,95%CI [0.92-23.60]显示出显着的改善,但不是PLA(11.26计数,95%CI [ ?0.077至22.60])。另外,没有明显的准备,运动表现或不利变化的重大变化。 结论: 用PWS150观察到选择性注意和反应抑制的一致性改进,但不准备或运动性能。]]>
