Recent studies have shown that nitrate (NO3^- ) supplementation via NO3^- rich beetroot juice (BR) preferentially improves vascular conductance and O2 delivery to contracting skeletal muscles. It is unclear, however, whether nitrate supplementation would enhance anaerobic exercise capacity. We examined the effects dietary nitrate on race performance and anaerobic power in the elite female university paddler specializing in kayak single 200m. Kayak paddler and track and field athlete as a control subject were administered BR ( ~ 6.4mmol of NO3^- per 70 ml) for 21 days. Regrettably,it was much difficult to make a fair judgment on the performance between pre and postrace time, as the environmental conditions of the race are greatly different. In kayak paddler, though maximum and mean power during Wingate anaerobic test (WAnT) could be impaired by the repeated WAnT, BR supplementation for 21days could keep them at a constant level to the second WAnT. Though the heart rates at starting point of each WAnT in kayak paddler could be increased by the repeated ergometer exercise, BR could keep it constant from second to forth WAnT. These data therefore provide a putative finding for the dietary inorganic nitrate for 21days induced improvements in anaerobic exercise capacity during WAnT in kayak paddler.}, pages = {230--239}, title = {硝酸塩経口摂取が女子大学生エリートカヌー選手の 無酸素性運動能力に及ぼす影響}, volume = {95}, year = {2020}, yomi = {マツナガ, スミコ and マツナガ, サトシ} }
