A study presented at the 7th Annual International Society of Sports Nutrition (ISSN) Conference and Expo proved that the consumption of phosphatidylserine (PS) can benefit cognitive function prior to exercise.
Making quick decisions and reducing the amount of errors at the beginning of a competition are crucial to the success in team sports and individual events. Improved cognitive function could benefit athletes and non-athletes in situations of mental and physical stress alike. PS has previously been shown to reduce stress and increase performance in runners, cyclists and golfers.
A randomized, placebo-controlled, double-blind, study led by Prof. Adam Parker, West Texas A&M University, along with co-workers from two universities, involved 14 males aged 18-30, who were involved in an acute resistance exercise bout. The goal of the study was to determine whether 10-day supplementation of 400 mg PS would improve cognitive function prior to and after a stress-inducing resistance exercise bout.
Cognitive performance was measured by the serial subtraction test (SST), a validated method in which subjects repeatedly subtract from 1,579 by intervals of seven. PS supplementation did reduce the time needed for a correct calculation by 21%, reduced the total amount of errors by 38% and increased the amount of correct calculations per error by 42% prior to exercise.
“Athletes get into a rhythm after they have succeeded on their first attempts whereas stage fright increases after first tasks have not been completed successfully,” said Dr. Martin Purpura, Managing Member of Increnovo LLC and co-author of the study. “Having your cognitive functions game time ready at the beginning of a competition or exam is crucial for individual and team success." Additionally, Scott Hagerman, president of Chemi Nutra, sponsor of the study and global leader in production, research, and intellectual property surrounding PS said, “It is well known that PS benefits mental capabilities as well as improves exercise performance, and this study adds to this convincing body of science.”
