161. Nutritional supplement practices of professional Ugandan athletes: a cross-sectional study (PubMed)

to collect data from 359 professional athletes participating in individual (boxing, cycling, athletics) and team (basketball, rugby, football, netball, and volleyball) sports. The data were categorized, and a Chi-square test was used for statistical analysis.Of the 359 athletes, 48 (13.4%) used nutritional supplements. Carbohydrate supplements, energy drinks, vitamin and mineral supplements, fish oils, and protein supplements were the most common supplements used by athletes. NS use was significantly (...) more common among athletes who played rugby and basketball (X2 = 61.101, p < 0.0001), athletes who had played the sport for 5-10 years (X2 = 7.460, p = 0.024), and athletes who had attained a tertiary education (X2 = 33.377, p < 0.0001). The athletes' occupation had no bearing on whether they used supplements. Nutritionists/dieticians, retail stores and pharmacies were the most common sources of NS products, whereas health practitioners, online media and teammates were the most common sources

162. Evaluation of Dietary Intakes and Supplement Use in Paralympic Athletes (PubMed)

Evaluation of Dietary Intakes and Supplement Use in Paralympic Athletes Dietary intakes and supplement use in Paralympic athletes remains largely unexplored, and specialized recommendations are lacking. The aim of this study was to evaluate nutrient intakes and supplement use in high-performance athletes with physical disabilities using three-day food records and a validated dietary supplement use questionnaire. A secondary aim examined gender differences in nutrient and supplement intakes (...) for vitamin A and folate. Commonly consumed supplements were vitamin D, protein powder, sport bars, and sport drinks. Analysis of diet and supplement use within this population shows several micronutrient deficiencies and irregular use of specific supplements. Athlete support and education is required to optimize nutrition in Paralympic athletes.

163. Acute citrulline-malate supplementation improves maximal strength and anaerobic power in female, masters athletes tennis players. (PubMed)

Acute citrulline-malate supplementation improves maximal strength and anaerobic power in female, masters athletes tennis players. Citrulline-malate (CM) is a precursor to nitric-oxide (NO) in the NO synthase (NOS) pathway and is suggested to increase exercise performance in younger individuals. With age, NO production decreases and augmented NO production may provide beneficial effects on sports performance among masters athletes (MAs).To examine the effects of acute CM supplementation on grip (...) within trials, but no significant differences were observed between trials regarding supplement consumed.These data suggest that consuming CM before competition has the potential to improve tennis match-play performance in masters tennis athletes. However, this study utilized a controlled laboratory environment and research evaluating direct application to on-court performance is warranted.

Decrease in Ionized and Total Magnesium Blood Concentrations in Endurance Athletes Following an Exercise Bout Restores within Hours-Potential Consequences for Monitoring and Supplementation. Magnesium is essential for optimal sport performance, generating an interest to monitor its status in athletes. However, before measuring magnesium status in blood could become routine, more insight into its diurnal fluctuations and effects of exercise itself is necessary. Therefore, we measured the effect (...) performed a 90 min bicycle ergometer test (70% VO2max) between 11:00 and 12:30. Whole blood samples were analyzed for iMg and plasma for tMg concentrations. Both concentrations decreased significantly after exercise (0.52 ± 0.04-0.45 ± 0.03 mmol/L and 0.81 ± 0.07-0.73 ± 0.06 mmol/L, respectively, p < .001) while no significant decline was observed during that time-interval on control days. Both, iMg and tMg, returned to baseline, on average, 2.5 hr after exercise. These findings suggest that timing

Essential Features of Third-Party Certification Programs for Dietary Supplements: A Consensus Statement. The presence of performance-enhancing drugs in dietary supplements poses serious anti-doping and health risks to athletes and military service members.

The study assessed the likelihood that a respondent who reported use of a specific complementary and integrative therapy as their first top therapeutic modality to enhance sport or athletic performance had perceived it helpful compared with those who used it for other non-sport-related reasons. Results • Complementary and integrative therapies were used by more than 14 million adults (20.5%) to improve athletic performance, with 97.6% of them perceiving therapies as helpful. The most used (...) therapies were yoga, herbal supplements, manipulation, and massage. The median age of those reporting specific use to improve athletic performance was slightly less than 38 y, and women were almost 3 times as likely as men to report therapies as helpful. Conclusions • Complementary and integrative therapies were used for improvement of athletic performance by respondents of the 2012 NHIS, with high satisfaction among users.

Combine the two, and you can imagine the ego of the average emergency physician. But underneath (...) all that bravado, we are all human . We all experience stress, and we all respond to stress in distinctly human ways. I like talking about performance under pressure precisely because we don’t talk about it.
