Previous observations demonstrate New Zealand blackcurrant (NZBC) extract to alter cardiovascular responses at rest without prior exercise. However, the prolonged effects of NZBC on blood pressure and heart rate variability following exercise are not known. Participants (n15 [five women], age: 31 ± 9 years, maximal oxygen uptake: 44 ± 9 ml·kg⁻¹·min⁻¹) undertook a control condition of 2 hr of lying supine rest. Subsequently, in a double-blind, placebo (PLA)-controlled, randomized crossover design participants completed 1 hr of treadmill exercise at 50% maximal oxygen uptake followed by 2-hr supine rest with blood pressure and heart rate variability measurement following a 7-day intake of NZBC and PLA. With NZBC, there was an increase in average fat oxidation (NZBC: 0.24 ± 0.11 vs. PLA: 0.17 ± 0.11 g/min, p = .005), and larger high-frequency relative power during the exercise (p = .037). In the 2-hr rest period, delta change for systolic pressure was larger with NZBC than PLA (Control vs. NZBC: −5.6 ± 6.4, Control vs. PLA: −3.5 ± 6.0 mmHg, p = .033) but was not different for diastolic or mean arterial pressure. There were no alterations in heart rate variabilities during the 2 hr following the exercise with NZBC. A 7-day intake of NZBC causes a larger postexercise hypotension response in young, physically active men and women following 1 hr of treadmill exercise at 50% maximal oxygen uptake.

之前的观察表明，新西兰黑加仑 (NZBC) 提取物无需事先运动即可改变休息时的心血管反应。然而，NZBC 对运动后血压和心率变异性的长期影响尚不清楚。参与者（n 15 [五名女性]，年龄：31 ± 9 岁，最大摄氧量：44 ± 9 ml·kg ^-1 ·min ^-1）进行2小时仰卧休息的对照条件。随后，在双盲、安慰剂 (PLA) 对照、随机交叉设计中，参与者以 50% 最大摄氧量完成 1 小时的跑步机锻炼，然后仰卧休息 2 小时，并在 7 小时后测量血压和心率变异性。 NZBC 和 PLA 的日摄入量。使用 NZBC，平均脂肪氧化有所增加（NZBC：0.24 ± 0.11 vs. PLA：0.17 ± 0.11 g/min，p  = .005），并且运动期间高频相对功率更大（p  = .037） 。在 2 小时休息期间，NZBC 的收缩压变化大于 PLA（对照与 NZBC：-5.6 ± 6.4，对照与 PLA：-3.5 ± 6.0 mmHg，p = .033），但没有 差异用于舒张压或平均动脉压。NZBC 锻炼后 2 小时内心率变异没有变化。对于年轻、体力活跃的男性和女性，在最大摄氧量 50% 的跑步机上运动 1 小时后，连续 7 天摄入 NZBC 会导致更大的运动后低血压反应。
