摘要

新西兰黑加仑(NZBC)可以提高年轻人的运动表现,可能是通过花青素诱导的心血管功能改变和血流量增加,然而,对老年人血压、功能性运动表现和认知功能的影响尚不清楚。在一项随机、双盲、安慰剂对照、交叉设计中,14名老年人(年龄:69±4岁,身高:172±9厘米,体重:85±12)服用NZBC提取物(600毫克·天-1 CurraNZ™)或安慰剂(PL, 600毫克微晶纤维素)7天(两种情况之间7天的洗脱期)。在第7天、服用胶囊后2小时,测量静息血压、认知功能(剑桥神经心理测试自动电池)和6分钟步行测试表现。摄入NZBC导致了下降(p

Effect of New Zealand Blackcurrant on Blood Pressure, Cognitive Function and Functional Performance in Older Adults.

New Zealand blackcurrant (NZBC) can increase exercise performance in young adults, potentially by anthocyanin-induced cardiovascular function alterations and increased blood flow, however, effects upon blood pressure, functional exercise performance and cognitive function in older adults is unknown. In a randomized, double-blind, placebo-controlled, cross-over design, 14 older adults (age: 69 ± 4 years, height: 172 ± 9 cm, body mass: 85 ± 12) ingested NZBC extract (600 mg·day-1 CurraNZ™) or placebo (PL, 600 mg microcrystalline cellulose) for 7-days (7-day washout between conditions). On day-7, 2-hours following consumption of the capsules, resting blood pressure, cognitive function (Cambridge neuropsychological test automated battery) and 6-minute walk test performance and were measured. Intake of NZBC caused a decrease (p < 0.05) in systolic (PL: 136 ± 14; NZBC: 130 ± 12 mmHg) and diastolic (PL: 84 ± 11; NZBC 78 ± 6 mmHg) blood pressure. There was no effect on 6-minute walk performance or cognitive function variables. Future research should address optimization of intake and examine cardiovascular responses during exercise.

期刊介绍: The Journal of Nutrition in Gerontology and Geriatrics publishes original research studies that are directly relevant to clinical and community nutrition issues that affect older adults. Epidemiologic and community-based studies are suitable for JNE, as are well-controlled clinical trials of preventive and therapeutic nutritional interventions. The Journal of Nutrition in Gerontology and Geriatrics invites papers on a broad array of topics in the nutrition and aging field, including but not limited to studies of: preventive nutrition, nutritional interventions for chronic disease, aging effects on nutritional requirements, nutritional status and dietary intake behaviors, nutritional frailty and functional status, usefulness of supplements, programmatic interventions, transitions in care and long term care, and community nutrition issues.
