Hello,
I would like to ask, from approximately what duration of aerobic activity (I understand that each of us is unique) it makes sense to supplement nutrients during sports and how to approach these "snacks." As an example, I think of a 42 km run, and on the other hand, an ultra-endurance cycling race (3 days straight on a bike with rest/sleep of about 1-2 hours per day).
In general, for stress situations lasting up to 2.5-3 hours, it is not strictly necessary to supplement anything other than pure fluids. In some cases, it can even be counterproductive; however, in situations of increased sweating, the fluids should include necessary minerals, which are a common component of electrolyte drinks.
When it comes to extremes, such as ultra-endurance races, the situation becomes more complex, as practice shows that due to extreme physical and mental stress, athletes react individually, and generally presented rules no longer apply. These are situations that athletes are very reluctant to address, because the only meaningful path to optimizing the nutrition system is through gradually gathered personal experiences, which is always a long-term endeavor. At this level, focus on the most important aspects:
1. Establishing regularity and time intervals between individual meals.
This is a challenge in itself, because having a plan is one thing, but then there is what the body says—if it doesn't want food at a given moment, you generally won't get anything into it; conversely, the digestive tract can retaliate with strong protests that significantly complicate subsequent performance. Still, there should be some plan because if you leave everything up to personal feelings, it often happens that an athlete lasts without food for long hours, and at the first break cannot control the ravenous urge caused by accumulated stress and nutrient deficiency, leading to a difficult-to-manage situation in terms of systematic dietary approach.
2. Setting the ratio of macronutrients.
The basis is always proteins, though even under extreme stress, large amounts are not necessary. The key is to allocate the proportions of carbohydrates and fats as energy sources. In recent years, low-carb systems have gained attention among endurance athletes, but based on my own experience, I must say that a high-carbohydrate approach works, and works well (if set correctly, i.e., ensuring enough fiber and polysaccharides).
3. Ensuring sufficient antioxidants and selected adaptogens.

Nutrition educator, lecturer, and author of the educational system and the ZOF learning application.
Mgr. Martin Jelínek has been systematically involved in nutrition education since 1999. He is the founder of ATAC, the educational company behind NutriCourses, and the author of an educational system focused on nutrition, healthy lifestyle, and the practical application of nutrition knowledge.
He graduated from the Faculty of Science at Masaryk University in Brno. Throughout his professional career, he has combined nutrition, education, and the practical application of acquired knowledge. His educational system also includes the ZOF (Zone of Optimal Functioning) learning application, where students turn theory into practical work with meal plans.
In 2007, he launched the first intake of a six-month course focused on the education of nutrition advisors. Over time, this course became the foundation for the further development of the educational system and a range of specialised courses.
