Summary: Research suggests that there are individual differences in academic achievement among children based on their aerobic fitness. This study examines the indirect effects of executive functions and intelligence in the relationship between aerobic fitness and academic achievement, providing new insights into the cognitive mechanisms underlying this relationship.

Summary: This study empirically investigated the relationship between physical literacy, motivation, satisfaction, and quality of life among university students in Taiwan. Results showed that motivation mediated the relationship between physical literacy and physical education satisfaction, while satisfaction further mediated the relationship between physical literacy and quality of life. Ongoing physical education was suggested to nurture the habit of lifelong participation in physical activity, enhancing quality of life.

Summary: This study compared the effects of resistance training (RT) and concurrent training (CT) with different protein intakes on muscle hypertrophy, strength, and performance. The results showed that a daily protein intake of 1.6g/kg is sufficient to maximize gains in lean mass, muscle strength, performance, and aerobic capacity during both RT and CT without significant effects on kidney and liver function.

Summary: The study found that continuous ingestion of food-derived oligopeptides accelerated total body triglyceride breakdown, non-esterified fatty acid uptake, and fat oxidation during both sedentary and exercise states. Elevated circulating and intracellular free amino acid flux may modulate the selection of substrates for metabolic pathways in conjunction with the release of neuroendocrinological factors that slow down carbohydrate metabolism via acetyl coenzyme A feedback inhibition. This may increase the availability of fatty acids for energy production, with free amino acids supplying more substrates for the tricarboxylic acid cycle. The findings of this study provide novel insight into strategies for promoting lipid metabolism in populations with dyslipidemia-related metabolic disorders such as obesity and for improving physiological functioning during endurance training.

Summary: High-intensity exercise can cause inflammation and affect the immune response. Fucoidans, a type of sulfated polysaccharide, may have anti-inflammatory and pro-immune effects. This study investigated the safety and efficacy of fucoidans on markers of inflammation and immunity after high-intensity exercise. The results showed that fucoidan supplementation had some effects on inflammatory cytokines, but did not influence exercise performance.

Summary: This study found that early absorption sources containing caffeine, such as chewing caffeinated gum and coffee mouth rinsing, have a positive effect on the performance of female table tennis players, particularly in functional and cognitive tests. However, the effect on skill tests was not significant.

Summary: This study aimed to investigate the weight loss practices in female fighters. The results showed that female fighters, regardless of weight divisions, lost an average of 4.5-6.6% of their weight before the official weigh-in.

Summary: The present study aimed to evaluate the effects of dietary supplements on athletic performance in elite soccer players. Caffeine supplementation may improve jump height and sprint ability, particularly in female players. Creatine supplementation may enhance sprint, agility, and jump performance in female players. Protein supplementation can improve sprint and jump performance between matches. Beverages with carbohydrates and electrolytes can be used as part of carbohydrate intake strategies but do not have a direct impact on athletic performance. Tart cherry juice may help maintain athletic performance after matches that cause force loss and muscle damage. Nitrate-rich beetroot concentrate can attenuate performance decrease after matches. Further investigation is needed for sodium bicarbonate supplementation. Yohimbine supplementation and the use of Resurgex Plus & REG; do not improve athletic performance in elite soccer players. More research with elite soccer players is necessary to provide better support and advice on the use of dietary supplements for performance enhancement.

Summary: Based on literature review and analysis, this study concludes that coffee is a complex mixture of compounds with varying effects on physical and cognitive performance. The physiological effects of coffee depend on factors such as dose, timing, habituation, nutrigenetics, gut microbiota differences, sex, and training status. Coffee and its components have been shown to improve performance in various activities, but more research is needed. The optimal dosing of coffee is approximately 2-4 cups, providing a caffeine equivalent of 3-6 mg/kg, 60 minutes prior to exercise.

Summary: This study examined the effects of maslinic acid (MA) supplementation on perceptual fatigue and muscle soreness in water polo athletes. The results showed that MA supplementation significantly reduced perceptual fatigue and muscle soreness during training by decreasing inflammatory factors. Additionally, MA was found to decrease inflammation and oxidative stress in both blood and skeletal muscle.

Summary: This study found that pre-exercise protein consumption does not significantly influence fat oxidation rates during exercise, and intake of 20g and 40g of protein can increase serum insulin levels. Resting energy expenditure is elevated post-exercise, with no interaction for protein dose.

Summary: This study analyzed the lipid profile of mature erythrocyte membranes in female football players and found that there were variations in fatty acid content during the competitive season. Compared to the general population, the athletes had increased levels of polyunsaturated fatty acids in their membrane lipid profile, along with a decrease in a specific omega-6 fatty acid called DGLA, which is involved in immune and anti-inflammatory responses. These findings suggest that membrane lipidomics can be used as a tool to assess the molecular characteristics of elite female football players and provide insights for future personalized nutritional strategies.

Summary: This article summarizes the results of a comprehensive review and critical analysis of the literature on the nutritional concerns of female athletes. The conclusions highlight the importance of tracking hormonal status and individual patterns, achieving adequate energy intake, tailoring carbohydrate intake to hormonal status, consuming high-quality protein close to exercise, and addressing fluid dynamics and electrolyte handling in female athletes. The article also emphasizes the need for more research on sex-specific supplementation and the inclusion of females in research studies.

Summary: This study aimed to determine the effect of repeated coffee mouth-rinsing (CMR) doses on specific performances of futsal players. The findings showed that repeated low and high doses of CMR are useful strategies to improve specific futsal performance, with higher dose CMR having a more profound effect on performance improvement than lower doses.
