This Fatty Acid May Boost Cognitive Function During and After Exercise
Consuming phosphatidylserine (PS) before exercise may increase cognitive function according to a study presented June 25th, 2010 at the 7th Annual International Society of Sports Nutrition (ISSN).
PS is an essential fatty acid that has been linked to reducing memory loss, Alzheimer's and dementia in previous studies.
For the current study, researchers from Texas A & M University recruited 14 males between 18-30 years of age.
The participants were given a supplement containing 400 mg of PS for ten days and their cognitive function was measured before and after a stress inducing exercise session.
Cognitive performance was measured by the serial subtraction test (SST), a well known measurement of cognitive function that involves repeatedly subtracting from 1,579 by intervals of seven.
The researchers found that PS supplementation reduced the total time it took a participant to calculate by 21%, reduced the total amount of errors by 38% and increased the amount of correct calculations per error by 42% prior to exercise.
The researchers say that these findings are helpful for athletes and non-athletes alike because PS supplementation may reduce the risk of potentially harmful errors when exercising.
These findings also build on previous research which shows that PS may benefit cognitive function and reduce the risk of dementia among older adults.
If you are looking to boost cognitive health, previous studies have also shown that omega-3 fatty acids, vitamin E and even caffeine may boost cognitive health and reduce the risk of age-related cognitive decline.
