The focus on nutrition takes a central role among elite athletes during the Winter Olympics, as it directly affects their ability to achieve maximum performance. According to the scientific journal Scientific American, which uses information provided by nutrition and sports professionals, the physical demands of these professionals imply a need for calories and nutrients that far exceeds that of an average person. Maintaining the balance between energy, recovery, and adaptation to the environment is the axis of their daily diet.
Why are carbohydrates essential for the performance of winter Olympic athletes?
The foundation of the winter Olympians’ diet is carbohydrates. According to Rebecca Hall, a sports nutrition specialist and former member of the nutritional support team for the British Olympic Committee, these molecules are the main source of energy for intense and prolonged activities. During training and competitions, the body uses muscle glycogen stores, which directly depend on a sufficient intake of carbohydrates.To conserve the necessary energy, athletes consume carbohydrates before, during, and after training sessions. This way, performance is maintained, fatigue is delayed, and recovery is facilitated more effectively. Daily caloric intake, according to Hall, can range between 3000 and 8000 calories, depending on the sport, the intensity of the training, and environmental conditions.

What is the role of proteins and fats in the diet of Olympic winter athletes?
In the winter Olympics diet, proteins and fats fulfill distinct and complementary roles. Lucy Mower, a high-performance nutritionist, highlights that protein is essential for muscle repair and development, especially after intense training or competition. Athletes prioritize lean protein sources, such as chicken, fish, eggs, and dairy products, to facilitate recovery and maintain muscle mass during the season. The correct distribution of protein throughout the day is key to optimizing muscle synthesis and adaptation to the training load.
Regarding fats, Mower explains that, although they do not constitute the main source of energy during intense exercise, they are necessary for the absorption of fat-soluble vitamins and the production of hormones. In long-duration sports or under cold conditions, fats can also become a useful energy reserve and contribute to regulating body temperature.What micronutrients are key for high performance?
The contribution of micronutrients is central to the nutrition of winter Olympians. Kerry McGawley, a researcher in physiology and sports nutrition, points out that vitamin D and iron stand out for their impact on the health and performance of athletes. In those who train in cold climates and with little sun exposure, vitamin D contributes to bone and muscle health, while iron is essential for the transport of oxygen in the blood.
