磷脂酰丝氨酸（PS）是一种存在于大多数动物和植物细胞膜中的磷脂。PS已被证明可以减轻跑步者、自行车运动员和高尔夫球手的压力并提高其表现。本研究的目的是研究含有PS的制剂在剧烈抗阻运动之前和之后对认知功能、情绪和内分泌反应的影响。18名下半身、阻力训练、大学年龄的男性以随机、双盲、安慰剂对照、交叉方式摄入14天的补充剂（IQPLUS Focus，提供400 mg大豆来源的PS）和安慰剂（PL）。经过14天的补充，参与者进行了一次急性下半身阻力训练。在运动前、运动后5分钟和运动后60分钟测量情绪（情绪状态概况，POMS）和认知功能（连续减法测试，SST）。在运动前和运动后5、15、25、40和60分钟收集静脉血样品。分析血样中的血浆皮质醇和睾酮。使用重复测量ANOVA分析数据。补充PS显著减少了正确计算SST所需的时间20%（每次计算减少1.27 s; PL：6.4 s，PS：5.13 s; p = 0.001），并将错误总量减少39%（PL：1.28 ± 0.69，PS：0.78 ± 0.27，p = 0.53），并且与PL相比，在运动之前或运动响应中，正确计算的量增加了13%（PL：22.1 ± 2.24，PS：24.9 ± 1.52，p = 0.07）。运动后，PS和PL之间的SST评分没有差异。有没有显着的变化方面的情绪或内分泌反应的运动作为一个结果的PS补充。补充PS显著提高了运动前的认知功能。认知功能的改善可以使运动员和非运动员都受益。PS似乎并没有影响情绪或内分泌反应之前或之后的阻力运动。
Phosphatidylserine (PS) is a phospholipid found in cell membranes of most animals and plants. PS has been shown to reduce stress and increase performance in runners, cyclists and golfers. The purpose of this study was to investigate the effects of a PS containing formulation on cognitive function, mood and endocrine response before and after intense resistance exercise. 18 lower body, resistance trained, college aged males ingested 14 days of supplement (IQPLUS Focus, providing 400 mg of soy-derived PS) and a Placebo (PL), in a randomized, double-blind, placebo controlled, cross-over manner. Following 14 days of supplementation, participants performed an acute bout of lower body resistance training. Mood (Profile of Mood States, POMS) and cognitive function (Serial Subtraction Test, SST) were measured prior to, 5 minutes after, and 60 minutes after exercise. Venous blood samples were collected prior to, and 5, 15, 25, 40 and 60 minutes after exercise. Blood samples were analyzed for plasma cortisol and testosterone. Data were analyzed using repeated measures ANOVA. PS supplementation significantly reduced the time needed for a correct calculation on the SST by 20% (reduced by 1.27 s per calculation; PL: 6.4 s, PS: 5.13 s; p = 0.001), and reduced the total amount of errors by 39% (PL: 1.28 + .69, PS: .78 + .27, p = 0.53), and increased the amount of correct calculations by 13% (PL: 22.1 + 2.24, PS: 24.9 + 1.52, p = 0.07) prior to or in response to exercise compared to PL. Following exercise, there was no difference in SST scores between PS and PL. There were no significant changes in regards to mood or endocrine response to exercise as a result of PS supplementation. PS supplementation significantly increased cognitive function prior to exercise. Improved cognitive function could benefit athletes and non-athletes alike. PS did not appear to affect mood or endocrine response prior to or following resistance exercise.
