Background: Managing metabolism for optimal training, performance, and recovery in medium-to-high-level endurance runners involves enhancing energy systems through strategic nutrient intake. Optimal carbohydrate intake before, during, and after endurance running can enhance glycogen stores and maintain optimal blood glucose levels, influencing various physiological responses and adaptations, including transitory post-endurance inflammation. This randomized trial investigates the impact of a high-dose 2:1 maltodextrin-fructose supplementation to medium-to-high-level endurance runners immediately before, during, and after a 15 km run at 90% VO intensity on post-exercise inflammatory stress.

Tissue availability of polyunsaturated fatty acids (PUFA) depends on several factors, including dietary intake, physical exercise, genetic variation, and metabolic turnover. However, there is limited evidence whether running training activity may influence indices associated with PUFA metabolism such as Omega-3 (ω-3) index and arachidonic acid (AA; 20:4ω-6)/eicosapentaenoic acid (EPA; 20:5ω-3) ratio. To examine the association between kilometers (Km) run per week and changes in ω-3 index and AA/EPA ratio.

The aim of this study was to elucidate the effects of dietary supplementation with Delphinol (trademark owned by MNL Chile) standardized maqui berry (Aristotelia chilensis) extract on products of lipid peroxidation in healthy, overweight, and smoker subjects.
Methods: In a double-blind, placebo-controlled design, 42 participants (age 45-65 years) consumed in random order either a standardized extract of maqui berry (162 mg anthocyanins) or a matched placebo, given 3 times daily for 4 weeks.
Overweight and obesity are the most common nutritional disorders in our age and are becoming more and more common worldwide. The most harmful consequences of an incorrect diet leading to overweight or obesity are a series of cardio-vascular diseases often leading to disability and death. In recent years various studies have shown that a reduction in caloric intake is the main factor involved in reduction of pathology risk.
