Effect of New Zealand Sujon blackcurrant on resting cardiovascular function in triathletes
نویسندگان
چکیده
Background Blackcurrant contains anthocyanin, a component known to induce vasorelaxation and vasodilation in rat aortic rings [1]. In humans, blackcurrant intake has been reported to increase peripheral blood flow [2], with higher anthocyanin intake having beneficial effects on cardiovascular function in women [3]. However, the effect of blackcurrant intake on cardiovascular function in endurance-trained athletes is unknown. We examined the effect of 1-week Sujon blackcurrant powder supplementation on resting cardiovascular function of trained triathletes.

Effect of New Zealand Sujon blackcurrant on cardiovascular responses during cycling in triathletes
Background Anthocyanin is a component known to induce vasorelaxation and vasodilation in rat aortic rings [1] and is present in high amounts in New Zealand Sujon blackcurrant. During typing work in humans, an activity of low intensity, peripheral blood flow was increased by blackcurrant intake [2]. It is not known whether anthocyanin would affect the cardiovascular responses at different exerci...
متن کاملNew Zealand Sujon blackcurrant lowers lactate accumulation during cycling in triathletes
Background Blackcurrant intake has been reported to increase peripheral blood flow in humans [1], potentially by anthocyanin-induced vasorelaxation and vasodilation [2]. Increased peripheral blood flow may affect the exercise intensity at lactate indicators (e.g. onset of blood lactate accumulation (OBLA) at 4 mmol L) and maximum oxygen uptake. We examined the effect of 1-week Sujon blackcurran...

We investigated the inhibitory effect of extracts of blackcurrant (Ribes nigrum L.) from New Zealand and Poland on 4 strains of influenza virus (IFV) by the inhibition of virus adsorption; pandemic flu from 2009-2010 (IFV-AH1pdm), Hong Kong flu (IFV-AH3), oseltamivir phosphate-resistant Russian flu (IFV-AH1tamr) and influenza virus type B (IFV-B). The inhibitory effect of the extracts of blackc...
متن کاملBlackcurrant Alters Physiological Responses and Femoral Artery Diameter during Sustained Isometric Contraction
Blackcurrant is rich in anthocyanins that may affect exercise-induced physiological responses. We examined tissue oxygen saturation, muscle activity, cardiovascular responses and femoral artery diameter during a submaximal sustained isometric contraction. In a randomised, double-blind, crossover design, healthy men (n = 13, age: 25 ± 4 years, BMI: 25 ± 3 kg·m-2, mean ± SD) ingested New Zealand ...

New Zealand blackcurrant (NZBC) extract increased 16.1 km cycling time trial performance. The aim of the present study was to examine the effect of NZBC extract on 2 × 4 km time trial performance. Ten male cyclists (age: 30 ± 12 years, body mass: 74 ± 9 kg, height: 179 ± 7 cm, body fat: 11 ± 3%, V̇O2max: 55 ± 7 mL·kg−1·min−1, mean ± SD) volunteered. Participants were familiarized with the time t...
