Individual EEG Asymmetry As a Predictor of Hydration Status During Exercise in the Heat

<p>Hydration behavior varies among individuals; continuous and correct fluid consumption behavior prevents decreased physical performance and severe dehydration, especially during extended exercise and hot environments. Therefore, the purpose of the present study was to examine individual frontal alpha electroencephalographic asymmetry index (FAI) score in eu-hydrated, hypo-hydrated, and exercise in well-trained men and assess if there is a correlation between FAI score and individual ad libitum fluid consumption behavior. Subjects were kinesiology major college students ranging from 21 to 29 years of age. Subjects were categorized either approach group (n = 8) with resting FAI score more than 0 or avoidance group (n = 3) with FAI score less than 0. All subjects performed a passive dehydration trial in a hot water bath and exercise trial. While larger sample sizes are needed to verify results, there was a moderate correlation between the higher change in FAI scores to water exposure (closer to the positive value) and the greater desire for fluid consumption at baseline (as expressed by 100-millimeter scale) only in the hydration trial with no significance (<em>r</em> = 0.6; <em>p</em> = 0.05). Also, there was a moderate correlation between the larger change in FAI score (higher affinity) to water exposure and the more ad libitum fluid consumption during exercise in the approach group (<em>r</em> =0.72; <em>p</em> < 0.05). These trends may indicate that changes in FAI score between resting and beverage exposure could provide patterns within individual ad libitum fluid consumption during exercise. However, there was no relationship between post-exercise or dehydration FAI scores and the desire for fluid consumption.</p>
