The ergogenic effect of arginine has been demonstrated in research focusing on its intake before exercise. However, in these studies, the effect of arginine in combination with other various metabolites were assessed. The aim of this study was to determine whether a single oral intake of arginine, without any other compounds, 60 minutes prior to exercise, modifies performance and exercise metabolism during a repeated Wingate anaerobic test.
Six healthy, active, but not highly trained volunteers participated in the study. Subjects performed three 30s all-out supramaximal Wingate Anaerobic Tests (WAnTs) with 4 minute-interval rest periods between WAnTs.
Arginine ingestion before exercise did not influence physical performance. Triple WAnTs resulted in a marked increase in white blood cell (WBC) count, lactate and ammonia concentrations, however there were no differences between arginine and the placebo trials.
Our data indicated that 2 g of arginine ingested in a single dose, neither induced nitrite/nitrate (NOx) concentrations changes, nor improved physical performance.
精氨酸的促力效应已在关注运动前摄入精氨酸的研究中得到证实。然而，在这些研究中，评估的是精氨酸与其他各种代谢物联合使用的效果。本研究的目的是确定在运动前60分钟单独口服精氨酸（不添加任何其他化合物）是否会在重复进行的温盖特无氧试验中改变运动表现和运动代谢。
六名健康、活跃但未经过高强度训练的志愿者参与了该研究。受试者进行了三次30秒全力的超最大强度温盖特无氧试验（WAnTs），每次试验之间有4分钟的休息时间。
运动前摄入精氨酸对身体表现没有影响。三次温盖特无氧试验导致白细胞（WBC）计数、乳酸和氨浓度显著增加，然而精氨酸试验和安慰剂试验之间没有差异。
我们的数据表明，单次摄入2克精氨酸既不会引起亚硝酸盐/硝酸盐（NOx）浓度变化，也不会改善身体表现。
