作者陆姣姣,安燕,许瑾,陈永强（2019）在《磷脂酰丝氨酸对射击运动员心理应激适应能力及脑内神经递质激活水平的影响》一文中研究指出：目的观察口服不同剂量的磷酯酰丝氨酸(PS)对射击运动员赛前心理应激适应能力和脑内神经递质激活水平的影响。方法将18名手枪射击运动员,随机分为3组,每组6人,分别为空白组、PS-400组(400mg/d)和PS-800组(800mg/d),实验组受试者在比赛前连续服用PS2w,空白组不使用任何营养品。营养干预前和干预后(2w后,比赛开始前),测试所有受试者的血清皮质醇、尿素氮、肌酸激酶值并进行心境状态量表(POMS量表)和匹兹堡睡眠质量指数量表(PSQI表)评分,同时采用脑电测试脑内神经递质激活水平,包括抑制介质(INH)、5羟-色胺(5-H T)、乙酰胆碱(ACh)、多巴胺(DA)、去甲肾上腺素(NE)和兴奋介质(EXC)。结果 18名受试者完成全部实验。2w后,三组受试者的皮质醇均显著升高,PS-800组的皮质醇绝对值和增量均显著低于空白组(P=0.025,P=0.016),PS-400组的皮质醇增量显著低于空白组(P=0.023)。与干预前相比,PS-800组在POMS量表中慌乱值评分显著降低(P=0.038),且干预后显著低于空白组与PS-400组(P=0.027,P=0.016)。两实验组受试者在PS补充2w后,睡眠质量分数均有下降。脑电测试显示,在全脑神经递质中,PS-800组的ACh和DA激活水平较干预前有显著升高(P=0.050,P=0.029),干预2w后与空白组相比,5-HT和DA水平均显著升高(P=0.049,P=0.019)。在各脑区方面,PS-800组的5-HT和DA激活水平在P4、T5、T6三个脑区均出现了显著升高(P<0.05),干预2w后在F4脑区的ACh,F7的ACh、DA,T5的DA激活水平均显著高于空白组(P<0.05),而在F3的INH和F7区的INH、NE激活水平显著低于空白组(P<0.05),兴奋性神经递质ACh和DA与抑制性神经递质INH和NE的激活呈现相反变化,脑电活动趋于同步化,更为协调。这种变化趋势在补充PS 400mg/的实验组中也被观察到,但与空白组的差异较小。结论补充PS 800mg/d能够降低射击运动员赛前血清皮质醇水平,在减轻压力、稳定慌乱情绪及改善睡眠质量方面发挥积极作用,并能够调节脑内中枢神经递质激活水平,从不同层面上提高运动员心理应激适应能力。[营养学报,2019,41(5):439-443]
