Food Composition for Omnium Cyclists

At Saturday, we are dedicated to amplifying athletic performance by means of strategic nutrition optimization. This approach necessitates a deep comprehension of food composition, factoring in digestibility, nutrient richness, and bioavailability. Even though food composition might not be a direct determinant of athletic prowess, it plays a pivotal role in an omnium cyclist's nutritional status and metabolic efficiency.

Proteins: Deciphering Quality and Digestibility

The assessment of proteins necessitates a thorough examination of their quality and digestibility. Protein quality is primarily determined by the profile of its amino acids. Out of the 20 amino acids, our bodies can produce 11 (non-essential), while the remaining 9 (essential) must be sourced from the diet. Proteins are identified as either complete or incomplete depending on whether they contain all essential amino acids. Nevertheless, by carefully combining different incomplete proteins, a complete protein meeting all essential amino acid requirements can be created. Animal products such as eggs, dairy, and meat offer complete proteins, whereas incomplete proteins like legumes and grains can be paired to offer a full spectrum of amino acids.

The digestibility of a protein, or the proportion of ingested protein that the body can utilize, is another key consideration. The Protein Digestibility Corrected Amino Acid Score (PDCAAS) is an effective tool for measuring protein digestibility, with a scale ranging from 0 to 1.0. Animal-based products typically score high on the PDCAAS, indicating superior digestibility and quality. Conversely, plant-based proteins often exhibit lower digestibility, primarily due to the presence of indigestible cellulose in plant cell walls, which obstructs the total absorption of protein. Hence, it's recommended that a considerable proportion of an omnium cyclist's protein intake come from animal sources, given their high quality and digestibility.

Carbohydrates: Concentrating on Digestion Duration and Nutrient Density

When analyzing carbohydrates, the focus is mainly on two aspects: digestion duration and nutrient density. The Glycemic Index (GI), a scale from 0 (lowest) to 100 (highest), is the reference metric. The GI assesses the speed at which carbohydrates are digested and subsequently absorbed into the bloodstream. Those carbohydrates that are rapidly digested will cause a fast increase in blood glucose, leading to higher GI values, while those that digest more slowly will cause a more gradual increase, thus lower GI values.

Both health and athletic performance are influenced by the GI. Lower GI carbohydrates like vegetables and whole grains often offer additional health benefits, such as fiber, micronutrients, and phytochemicals. However, from a performance perspective, consuming high-GI carbohydrates like simple sugars during exercise can supply glucose to the bloodstream quickly while minimizing gastrointestinal discomfort. A good practice is to opt for lower GI carbohydrates the farther away from training you are.

Fats: Distinguishing the Types

The quality of fat primarily relies on its type: monounsaturated, polyunsaturated (including omega-3 and omega-6), saturated, and trans fats. Although fats form a crucial part of macronutrients, their role in athletic performance is somewhat indirect, primarily focusing on promoting health. Omnium cyclists should aim to incorporate monounsaturated, polyunsaturated, and saturated fats in their diet while restricting or completely avoiding trans fats due to their potential negative health impacts. Foods like nuts, avocados, and canola oil are rich in monounsaturated fats, while polyunsaturated fats can be obtained from fatty fish and chia seeds. Animal-derived products like cream and cheese are sources of saturated fats.

Conclusion

To conclude, while food composition might not be the primary determinant of athletic performance, its impact is considerable. A meticulously planned diet that takes into account the protein quality, carbohydrate GI, and fat type can effectively optimize an omnium cyclist's performance. At Saturday, we will continue to build on this commitment to athletic performance through the strategic optimization of nutrition.
