41 Objective. To clarify the physiological basis of potential eccrine gland impacts on TDC values. Background. TDC values largely depend on tissue water and are used to assess edema extent and changes. The effect of eccrine glands and their activation on TDC values is unknown. Methods. Major factors whereby eccrine glands may affect TDC values have been investigated and methods for experimental assessment of the likely dependency has been formulated. Results. Whole body has approximately 4 X 10 6 eccrine sweat glands with the forehead containing 360 ± 50 /cm 2 and forearm 225 ± 25 /cm 2 . Eccrine tube length and diameter are on average 5mm and 0.02-0.05mm respectively. Sweat is composed of 99.0-99.5% water with about 75 Mm Na + and Cl - thus is likely to affect TDC values in a pore-density and activation state dependent manner. Pilot measurements on forehead and forearm suggest that heat-induced sweating can elevate TDC-measured estimates of tissue water by as much as 30% and possibly more. To relate such changes to pore-density a method to measure pore-density is needed and is being developed along with a mathematical model to assess the possible range of effects Conclusion. The amount and content of sweat released upon activation appears to have the potential to significantly impact TDC values. The significance of this fact lies in the way such activation may confound TDC measurements aimed at detecting and tracking edema or lymphedema. The future research focus should thus be to characterize TDC value dependency in relation to measured pore-density.

The purpose of these case reports was to do a follow-up investigation of five subjects on a high-protein diet over another 1-year period. Background. The long-term effects of a high-protein diet are not well established particularly in well-trained athletes. Methods. Five healthy resistance-trained men (mean ± SD; age 30 ± 5 yr; height 177.9 ± 5.5 cm) volunteered to continue to consume a high-protein diet (>2.2 g/kg/d over another 12-month period). Subjects came to the lab every 6 months to assess body composition. Subjects continued to provide dietary self-reports via the MyFitnessPal mobile app (>150 diet recalls per year). No other instructions were given. Each subject was provided with protein powder so they could attain their protein intake goals. A basic metabolic panel was assessed in a fasted state. Results. Two years on a high-protein diet have no harmful effects. Conclusion. Consuming a high-protein diet for 2 years in resistance-trained men has no deleterious effects on liver or kidney function. Subjects also demonstrated above average bone mineral density.

Davenport, Ph.D., Associate Professor, Dr. Pallavi Patel College of Health Care Sciences, Nova Southeastern University Objective. This study was conducted to compare the gender related experiences in motivation for male and female adults who regularly engage in online gaming. It explores the variety of experiences between genders and adults of various ages. Background Much of the online gaming research focuses on the male population, providing little
