Purpose This study aimed to evaluate the nutrient intakes and diet quality of national youth badminton players participating in summer camp training in 2016. Methods Total of 40 middle school players and 60 high school players were included in the study. Two players with skipped meals were excluded from the final target. Food intake data for the 3-day using 24-hour recall method were obtained and analyzed using the CAN-pro 5.0 (Web ver. Korean Nutrition Society, Korea). Differences in nutrient intakes and diet quality were compared between middle school players and high school players using independent samples t-test. Results Intakes of vitamin C, vitamin E, vitamin B6, folic acid, calcium, chloride, magnesium, and zinc in both groups were lower than (RNI) recommended intakes of KDRIs. On the other hand, intake of sodium significantly exceeded the recommended nutrient intake (RNI) of KDRIs in both groups. The NARs (Nutrient Adequacy Ratio) of vitamin C, vitamin B6, folate, calcium and zinc were less than 0.75 in both groups. The NAR​s ​of 11 nutrients except for folic acid were significantly lower in high school players. The MAR (Mean Adequacy Ratio) of middle school players was 0.78, significantly higher than 0.64 of high school players. The INQs (Index of Nutritional Quality) of vitamin C, vitamin B6, folic acid, calcium and zinc were less than 0.75 in both groups. The INQs of vitamin A, vitamin B6 and zinc were significantly lower in high school players. On the other hand, the total DDS (Dietary Diversity Score) of high school players was 3.88, significantly higher than 3.29 of middle school players. The DDS of fruit group as well as milk and dairy group were particularly low. Conclusions The results suggest that balanced diet managed by professional dieticians along with nutrition education should be implemented to improve nutrients intake and diet quality of national youth badminton players.

8050-0 83 05v 02 103 POLY(VINYLIDENE FLUORIDE)This project goal was to determine the maximum pyroelectric effect possible from poled poly(vinylidene fluoride) (PVF2). While much else was accomplished, which will be described below, we found no evidence that the pyrolectric coefficient of PVF2 could be made much higher than has already been achieved. AchievementsThe major achievements under this project were:1. High molecular weight PVF2 and copolymers with vinyl fluoride VF were made. Control over molecular weight was S. The melting and annealing behavior of our synthesized PVF 2 was compared to that of commercially produced materials, as our material had little H-H structure and no contaminating material. We found that our materials recrystallized faster than the commercial materials, but annealled Tm's were all close. We postulated that our materials had less branching which allowed them to reach higher Tm's and higher % crystallinity in a short time, compared to commercial He was supported on the DARPA grant until it expired, and has continued the research since.
