Dietary supplement improves golf game helping golfers hit the ball better
Phosphatidylserine (PS) is a component of the cell membrane; the outer boundary of the cell that controls what goes into and out of your cells. There is evidence that PS, already known for its ability to improve memory and cognitive functions, can help the body bounce back better from intense physical activity and also improves concentration while reducing mental stress.
Scientists at the University of Paderborn in Germany reasoned that PS may be beneficial in golf; a sport requiring high levels of concentration and coordination. They evaluated the performance of 20 golfers whose handicaps ranged from 15 to 40. The golfers were then given either 200mg of PS daily or placebo for 42 days. Before taking PS the golfers averaged 8.3 good ball flights out of 20 tee-offs when aiming at a green 135 meters away (about 443 feet). After the six-weeks of PS supplementation they averaged 10.1 good flights out of 20 and their stress level also improved. This is a statistically significant improvement in good ball flights. The golfers taking placebo had no improvement in ball flights or reduction in stress level.
The findings suggest that the supplement improved concentration by blunting the stress response, thus improving performance. The study is published in the December 4th, 2007 issue of the Journal of the International Society of Sports Nutrition.
