Brief Summary

The purpose of this study is to determine the effects of nooLVL containing arginine and inositol supplementation on executive function and memory prior to and following playing video games.

Detailed Description

Gaming or "E-Sports" has become a very popular activity particularly among younger individuals. It requires quick reactions, executive function, memory and fine motor skill. In E-Sport competitions and tournaments, E-Sport players often play for hours per session over a series of days. Thus, the ability to maintain cognitive and executive function, concentration and fine motor skill is paramount. Two recent studies have evaluated the effects of ingesting bonded arginine silicate (ASI) and ASI with additional inositol on cognitive function. In the first study, ASI supplementation (1,500 mg/d for 3 days and 14 days) significantly improved the ability to perform complex cognitive tests requiring mental flexibility, processing speed and executive functioning. In the second study, adding 100 mg of inositol to the ASI significantly improved cognitive function in gamers after playing video games for one hour. This study is designed to assess the effects of bonded arginine silicate and inositol ingestion on reaction time and cognitive function prior to and following a 1-hour gaming challenge.
