概要:

We examined the effects of vitamin C supplementation on neutrophil function during exercise loading.Neutrophil functions, namely the reactive oxygen species （ROS） production capability, neutrophil phagocytic activity（PA） and serum opsonic a … ctivity （SOA） were measured before and after a 2-hour unified loading exercise （ULE）both before and after a 7-day intensified training camp for 22 male judoists. The parameters were assessed neutrophilcount, myogenic enzymes, vitamin C in serum, SOA, PA, ROS production capability, body composition, and so on.Subjects were randomly assigned to two groups; the VC group （daily diet supplementation of 1,500 mg vitamin C）and the Control group （no vitamin C supplementation）. The post-camp pre-ULE vitamin C level was higher in theVC group than in the Control group, though no such difference was seen at pre-camp. As for neutrophil function,although the typical changes seen following a single bout of normal exercise, namely an increase in SOA and ROS,and a decrease in PA, were recorded following the pre- and post-camp ULEs in both groups, significant differencein change rates were not seen between both groups. In conclusion, vitamin C supplementation had no significantinfluence on changes in neutrophil function. 続きを見る
