I have chosen to interview a tennis player, “John”. Although not a professional tennis player he competes with family members every other weekend. In addition to eating a well balanced diet and maintaining a healthy weight John keeps himself hydrated by drinking sports drinks, which he believes, gives him an edge. His sports drink of choice is Gatorage Tiger because it has L-Theanine and advanced electrolytes.
L. Theanine is an amino acid, which is found in tea, it claims to help support and maintain mental acuity and focus. Research shows that L-Theanine, directly stimulates the production of alpha brain waves, creating a state of deep relaxation and mental alertness similar to what is achieved through meditation. Second, L-theanine is involved in the formation of the inhibitory neurotransmitter, producing the key relaxation effect resulting in improved memory. There are currently no known side affects.
Gatorade Tiger has 25% more electrolytes than any other sports drink. The hydration requirement, which determined the amount of electrolytes, was done by measuring the sweat rate, sweat electrolyte concentration, fluid and electrolyte balance, energy needs and strategy for hydration. Research has shown that electrolytes are lost during sweating and must be replaced in order to avoid dehydration, which may be caused by exercise.
My interview with the tennis player indicates to me that even a casual athlete is concerned about supplementation and is seeking an edge over the competition, which supplements promise to deliver. Although some research on L-Theanine shows that it cause relaxation and alertness there is no research to support that it helps an athlete with their game. I suggested to John, the tennis player that as long as he stays hydrated during the game eats well-balanced meals and stays away from supplements that should be enough of an edge on his opponent to help him win the game.
