The aim of our work is to highlight nutritional requirements/nutritional assessment, the importance of daily dietary intake in combat players, which increasingly includes a broad range of sports nutrition supplements, and the roles of vitamins, minerals and proteins, combined with antioxidants and strength training, in muscular performance. The main nutrients required in the daily diet of combat players, the mechanisms of action, the main outcomes and possible side effects are summarized. Special attention is paid to natural supplements and their importance and advantages over synthetic ones, along with future trends of development. Copyright Simona Cavalu et al.


The Roles of Antioxidants and Strength Training in Muscular Performance
During exercise, the metabolism is accelerated, oxygen consumption is high and the production of reactive oxygen species (ROS) increases. In addition, after muscle contraction, phospholipase A2 is activated, which initiates a cascade of enzymes, resulting in the formation of ROS. On the one hand, exercise-induced ROS have negative effects, causing altered cellular structure and function and, consequently, muscle damage, immune dysfunction and fatigue. On the other hand, ROS formation after exercise can also have beneficial effects, such as stimulating glycogen resynthesis and reducing susceptibility to infection while initiating and promoting adaptative responses to training, thus enhancing athletic performance.

Nanotechnological Tools for Nutraceuticals and Functional Foods
The individualization of meals based on biometric data has become a significant trend in modern nutrition. This study has been spurred on by technological developments in various domains, including analytical instrumentation, biotechnology, computers and data processing . As a result, personalized dietary gadgets tailored to a particular individual’s requirements could be developed. Personalized diets could advise a person to eat more of certain food groups. On the other hand, several food and nutrition companies work on functional foods and beverages enhanced with specific nutrients or nutraceuticals. Many of these things will be dependent on colloidal delivery technologies, which can incorporate a range of bioactive compounds into foods and beverages. These individualized diets can be adapted to an individual’s needs in various ways, including combining multiple nutrients in a single delivery system or integrating multiple delivery systems containing different nutrients, as we will see later. However, there is presently no information on the appropriate type and concentration of various bioactive components
to distribute to specific individuals, which will have to be discovered when colloidal delivery systems are constructed. As a result, future research should consider this much broader perspective, including advanced development in designing nanostructures with new or significantly improved attributes for the implementation of novel nutraceuticals in sports nutrition.
