简要总结
Phosphatidylserine is a phospholipid found in high concentrations in the brain and nervous tissues along with naturally occurring in many foods. It has been extensively studied for its effects on improving cognitive function, learning, memory and alleviating stress. However, more recently it has been proposed that phosphatidylserine could improve exercise capacity. The mechanisms of proposed action are difficult to distinguish because of the limited research and therefore the purpose of this study is to identify the proposed mechanism of action of phosphatidylserine supplementation and to establish whether these mechanisms will have an effect on time trial performance in trained male cyclists.
