Food high in (poly)phenolic compounds, such as anthocyanins, have the potential to improve exercise recovery and exercise performance. Haskap berries are rich in anthocyanins, but no research has examined the potential to improve human performance. The aim of this study was to determine the influence of Haskap berry on parameters of endurance running performance.
Using a double-blind, placebo controlled, independent groups design, 30 male recreational runners (mean ± SD age, 33 ± 7 years; stature, 178.2 ± 7.2 cm; mass, 77.7 ± 10.6 kg; V˙O, 52.2 ± 6.6 mL/kg/min) volunteered to participate. Following familiarisation, volunteers visited the laboratory twice (separated by seven days) to assess submaximal, maximal and 5 km time trial running performance. After the first visit, volunteers were randomly assigned to consume either the Haskap berry intervention or an isocaloric placebo control.
There were modest changes in heart rate and V˙O at submaximal intensities ( < 0.05). Time to exhaustion during the V˙O test was longer in the Haskap group by 20 s ( = 0.031). Additionally, 5 km time trial performance was improved in the Haskap group by ~21 s ( = 0.016), which equated to a 0.25 km/h increase in mean running speed compared to the placebo control; this represented a >2% improvement in running performance.
The application of this newly identified functional food to athletes has the capacity to improve endurance running performance.
富含（多）酚类化合物的食物，如花青素，有可能改善运动后的恢复和运动表现。哈斯帕莓富含花青素，但尚无研究检验其提高人体表现的潜力。本研究旨在确定哈斯帕莓对耐力跑步表现参数的影响。
采用双盲、安慰剂对照、独立分组设计，30 名男性休闲跑步者（平均 ± 标准差年龄 33 ± 7 岁；身高 178.2 ± 7.2cm；体重 77.7 ± 10.6kg；V˙O 52.2 ± 6.6mL/kg/min）自愿参加。在熟悉阶段后，志愿者两次（间隔 7 天）访问实验室，评估次最大、最大和 5km 计时赛跑步表现。第一次访问后，志愿者被随机分配到哈斯帕莓干预组或等热量安慰剂对照组。
在次最大强度下，心率和 V˙O 有适度变化（<0.05）。V˙O 测试中的力竭时间在哈斯帕组延长了 20 秒（=0.031）。此外，5km 计时赛表现也在哈斯帕组中提高了约 21 秒（=0.016），与安慰剂对照组相比，平均跑步速度提高了 0.25km/h；这相当于跑步表现提高了 >2%。
将这种新发现的功能性食品应用于运动员，有可能提高耐力跑步表现。
