Description

It has been shown that increased consumption of carotenoids, specifically lutein and zeaxanthin, found in dark leafy green vegetables can improve visual processing speeds and cognitive efficiency. For athletes, this can mean that greater consumption or focus on adding those to one’s diet can possibly improve not just reaction time, but rate of force development as well. My project was a visual-motor reaction time survey study in rock climbers aiming to see if there was a significant difference between visual-motor reaction time (VMRT) between groups of climbers who consumed on average more dark leafy green vegetables throughout their week compared to those who consumed less. This was done through the use of a dynamometer linked to a color changing screen. Participants were instructed to place their hand on the dynamometer, with their thumb on a pressure pad linked to the screen in front. They would press the pad to prime the screen, which would then randomly change color. When the color changed, they would then conduct a maximal effort 3 second pull on the dynamometer. This allowed us to see their VMRT through initial force production in the milliseconds they reacted to the change in screen and lbs generated in that time. With research currently ongoing, the hypothesis would be supported if the higher vegetable intake group is shown to generate a larger percentage of their 3s max force sooner compared to the groups who consume less dark leafy green vegetables.
